What is the difference between vacuum switch and air switch, which is suitable for the home

Due to the relatively small electrical load in the family, even when the most serious short circuit occurs, as long as the rated current is suitable for the air switch can meet the requirements, if you choose the circuit breaker with leakage protection function, it is more safe and reliable, the vacuum switch is mostly used in power generation and distribution and industrial electricity, usually the ability to flow and cut off the current and the ability to extinguish the arc is much better than the air switch suitable for use in the family, and the special material used in the vacuum switch makes its insulation performance very high, which can be used in the high-voltage circuit. In addition, at present, because vacuum switches are mostly used in high-current and high-voltage systems, vacuum switches with small rated current suitable for household use are usually not designed and manufactured, and some are overused.

Supplement: The use of air switches with leakage protection function in the family, as long as the selected rated current is appropriate, it is enough to meet the safe and reliable electricity consumption, and it is not necessary to estimate and find a suitable vacuum switch for home use.

Vacuum switches are generally used for high voltage or high currents, as the name suggests, the contacts cut off the current in a vacuum to avoid the ionization of the air and arcing.

I haven't heard of vacuum switches, only air switches, safety is a comprehensive thing, and you can buy it in major shopping malls.

Vacuum switch and air switch are both switches, but the arc extinguishing medium is different; The air switch relies on air for arc extinguishing, so it is suitable for low-voltage systems; The vacuum switch encloses the switch in a container (such as a glass bubble), and then pumps into a vacuum, and relies on the vacuum to extinguish the arc, and the arc extinguishing effect is good, so it is used in high-voltage systems;

Of course, our family uses low-voltage electricity, so we have to choose low-voltage air switches.

The air lift switch is particularly important in our daily life, and in the process of use, there is a problem, which has a great impact on the safety of the family. As for the model selection of air switches, have you ever learned about it? Today I will introduce to you the model selection of air switches and what are the characteristics of household air switches.

Model selection for the air switch.

1. At present, most of the air switches used in our families are DZ series, and this kind of air switch has the design of a small circuit breaker, which can better protect the safety of electricity and prevent leakage. There are many models, briefly to introduce a few, such as C16, C25, C32, C40, C60 and so on, of which C refers to the jumping current of the fan, which plays a good role in protecting the electricity at home.

2. The air switch that is often used in the industry is completely different from the household air switch, and the power circuit is usually DW model, or DZ model, and the model is divided into etc., in A. The rated current of this kind of air switch, less than a few amperes, more than 100 amperes, the key is to see where it is used, like the ordinary DZ47-63 series of air switches, its maximum current is set at 63A. For different types of air switches, the maximum current is different.

What are the characteristics of household air switches.

1. The air switch we often use in the family not only protects the total power supply, but also protects the power supply of each fulcrum, when a branch of the home is short-circuited, the air switch will react, trip immediately, and cut off the power supply, so that it can effectively protect other electrical appliances from being damaged, and prevent the occurrence of some serious situations.

2. The air switch used at home belongs to the 2P model, and the single pole is used to protect the circuit of the branch. If the rated current in the air switch will be small, it is very easy to cause the air switch to trip, which will cause indoor power failure at every turn; However, if the rated current of the air switch is too large, then it will not be able to protect the safety of electricity, so when installing the air switch, it is necessary to pay attention to the selection of the rated current.

3. If it is a small air switch, then its rated current is generally from a few amperes to hundreds of amperes, and you need to choose the specifications suitable for your own use, so as to be able to play the real role of air opening and closing.

Dear Kiss I am happy to answer for you, my answer is as follows: choose the air switch according to the following method: The air switch for home use belongs to the C-curve.

Therefore, when it comes to air switches for household use, we choose C-curve air switches. The air switch of the C curve is our common C10A, C16A, C20A, C25A, C32A and other different models, where the number represents the rated current, and the letter C represents the type of trip curve. 2.

The rated current of the air switch must be selected according to the calculated current of the load circuit of the air switch. For example, if the calculated current in the loop is 10A, then it is selected according to the multiplication of 10, which is 12A.

The air switch is a necessary electrical safety protection device in our life, and its function is a special safety device to protect the circuit through the relevant electrical energy reaction. Everyone should know that the greater the electrical energy, the greater the heat and heat energy generated, so it is more prone to danger, therefore, the air switch can automatically implement the power-off function when we overload the electrical energy, to ensure the overall safety of the circuit.

In the circuit protection device, the fuse and fuse device are very popular in the past, the fuse is a kind of wire with slightly larger resistance and lower melting point, when the current through the circuit exceeds the load, it will produce strong heat energy due to the resistance, resulting in the fuse blowing and causing the circuit to be broken and protect the circuit.

Compared to fuses, air switches are reusable and have a higher level of safety, which is why air switches are now widely used in various fields. Generally speaking, air switches are roughly divided into three types and three types of open circuits.

Magnetics space:

First of all, the first type of air switch is a protective device that uses an electromagnetic type to break the circuit. Similarly, when the current in the circuit exceeds or reaches the rated value, the magnetic circuit breaker of the air switch will generate a strong enough magnetic force to attract the switch to reset the operation, so as to achieve the circuit break. The magnetic air switch is also the easiest for us to understand its working principle of a type of air switch, and its range of use is also relatively wide, but we all know that since it will produce a magnetic effect, then when the air switch works normally, it will generate a magnetic field around it, and the magnetic field is harmful to the human body.

Therefore, the safety of the air switch is relatively low.

Thermal element air switch:

Thermal element air switch is a kind of air switch that uses heat to cause switch deformation to complete circuit breaking, usually it will be used in conjunction with magnetic air switch to achieve the function of double insurance. When the current in the circuit reaches the rated value but the magnetic switch is not broken, the thermal switch will be deformed due to the amount of heat, and the circuit will be disconnected to ensure the safety of the circuit.

Duplex trip air switch:

The tripping mechanism is a linkage device in an air switch. The tripping method of the thermal element principle mentioned above for the break-circuit operation is an inverse time limit action, that is, the heat generated by the electrical energy causes the bimetal sheet to bend and cause the tripper to act. In addition, this tripping method also has an instantaneous operation mode, the iron core and the related iron mechanism are connected, and when the current reaches the rated value, it will prompt the tripper to move to break the circuit.

In terms of circuit opening mode, air switches are generally divided into these three types, of course, in order to ensure the functional integrity and safety of air switches to the greatest extent, the current air switches are basically operated with each other in these three ways. , you can get it for free

What is a vacuum switch? Let's introduce the vacuum switch from several aspects.

The vacuum switch is an automatic measurement and control system of pressure, using the principle of pressure sensor, built-in high-precision sensor design to prevent the pressure in the system from being too high or too low, output the switch signal, to ensure the accurate and stable operation of the equipment under unattended controller. A vacuum switch is a pressure protection automatic controller for vacuum systems. When the vacuum pressure in the system is greater than the set point, the controller will automatically cut off the circuit and send a signal to ensure the normal operation of the system.

Negative pressure pressure switch, also known as vacuum switch, is an intelligent instrument integrating negative pressure measurement, display and control, which has the characteristics of simple operation, easy installation, high precision and strong function.

The pressure switch has the functions of reverse control, delay control, leakage protection, password protection, one-key error clearing, and a variety of pressure switching, which can be used for the measurement of various vacuum levels, and can be used with various vacuum pumps.

The working principle of the vacuum switch.

A vacuum switch is a pressure protection automatic controller for vacuum systems. When the vacuum pressure in the system is greater than the set point, the controller will automatically cut off the circuit and send a signal to ensure the normal operation of the system. When the pressure in the system is higher or lower than the safety pressure, the pressure sensor in the controller immediately acts, so that the contacts in the controller are connected or disconnected, and the equipment stops working at this time; When the pressure in the system returns to the safe range of the equipment, the pressure sensor in the controller immediately resets, so that the contacts in the controller are connected or disconnected, and the equipment works normally.

Mechanical vacuum switches are purely mechanical deformation resulting in a micro-switch operation. When the pressure increases, the vacuum switch acts on different sensing pressure and fighting force components (diaphragm, bellows, piston) to produce deformation, which will move upward, and finally activate the micro switch at the top through the mechanical structure such as the railing spring, so that the electrical signal is output. The mechanical pressure switch setting method is continuous displacement type in terms of functional principle, and the set point can be set at a single point and up to 3 different set points.

Main features of vacuum switches:

1. It adopts inch pipe threaded quick connector or copper pipe welded installation structure, which is flexible in installation, easy to use, and does not need special installation and fixation.

2. The plug-in wire connection can be selected by the user.

3. The sealed stainless steel inductor is safe and reliable.

4. Within the pressure range, it can be manufactured according to the pressure value arbitrarily selected by the user.

There are two types of pressure switches: mechanical and electronic, and there are many kinds of mechanical pressure switches and electronic ones.

Vacuum switch function.

1. It can realize the function of stopping the upper limit and starting the lower limit; (It can also be reversed).

2. The starting delay can be set to prevent the frequent opening of the motor from causing damage and noise;

3. KPA, BAR, PSI multiple pressure unit switching;

4. One-key clearing function;

5. It has the function of pipeline leakage protection;

6. Low power consumption, not exceeding;

7. Shock-resistant, anti-interference, fast response and stable performance.

Hello, air switch and switch are two different types of electric rolling front gas components.

A switch is an electrical component used to control the switch of the circuit base, and is usually used to control the switch of electric lights, electrical appliances and other circuits. The switch usually consists of a movable metal sheet and a fixed metal sheet, when the switch is in a closed state, the two metal pieces are in contact and the circuit is energized; When the switch is in the open state, the two metal pieces do not touch, and the circuit is de-energized.

An air switch is an electrical component used to control high-voltage circuits, usually used to control the switches of the power system. Air switches are similar in structure to switches, but they have a large disconnection distance between metal sheets, usually a few centimeters to tens of centimeters, and are able to withstand higher voltages and currents. Air switches are usually gas-insulated and are able to maintain stable insulation performance at high voltages.

Therefore, the difference between an air switch and a switch is its purpose and structure. Switches are usually used for the control of low-voltage circuits, while air switches are used for the control of high-voltage circuits. The structure of the air switch is more complex, and it needs to be gas-insulated, which can withstand higher voltages and currents.

1.The biggest difference between an air switch and a normal switch is what it does.

A normal switch simply turns the circuit on or off, while an air switch disconnects a high-current circuit for a short period of time.

2.Air switches have a different design and structure from ordinary switches due to the need to disconnect high-current circuits in a short period of time.

Air switches generally have an adjustable thermal element, and when the current exceeds the rated value, it causes the heat to rise, activating the trigger, thus disconnecting the circuit.

3.Air switches are widely used in high-voltage and high-current circuits, such as circuit breakers in power transmission and distribution systems, but they are less commonly used in Puxiang call-through homes.

Ordinary switches are commonly used in various electrical equipment in daily life, and are often used to turn on or off lights and electric fans in the hall.

In conclusion, the main difference between an air switch and a normal switch is in aspects such as its function, design, and scope of use.
