Which brand of indoor high voltage vacuum circuit breaker is good?

If you don't have a bad money, it is recommended to use ABB, and there is only one switch factory with a recall mechanism in the Chinese market.

The switch produced by domestic manufacturers can be regarded as a good thing if the material is sufficient, and it cannot compete with international brands in terms of technology and performance.

This is divided into domestic and foreign, and now the domestic vacuum circuit breaker is also relatively stable in terms of performance, and there is a vacuum circuit breaker that is doing better.

Cooper (Ningbo) Electric****.

VN3-12E is cost-effective **or preferred for use.

ABB price is high quality, poor after-sales. Jiangsu Senyuan can be selected in China, and the quality can be, and the key is that the after-sales service is guaranteed.

Anhui Senyuan's is also very good.

The circuit is often used in people's lives, but it also has great risks, especially in a specific environment, the risk factor is extremely high, and industrial production is inseparable from a variety of seepage macro and high voltage operations, in order to ensure the safety of operation, people have created a high voltage vacuum circuit breaker. High-voltage vacuum circuit breaker is only suitable for specific places, and is used more frequently in industry, it is precisely because of its important role that the quality of high-voltage vacuum circuit breaker needs to be very good.

There are many models of high-voltage vacuum circuit breakers, we need to choose the corresponding models according to the environment used, and the current size and voltage are important bases for choosing high-voltage vacuum circuit breakers. High-voltage vacuum circuit breaker may not be common in our lives, but its role in the industry is still very large, a high-quality manufacturer can ensure its quality, but also to ensure our safety in industrial use, then we should be extra cautious when choosing manufacturers, as far as possible to choose the best.

The top ten high-voltage vacuum circuit breaker brands include Shaanxi Taikai Electrical Equipment **** and other enterprises! The Company's products include 35kV column vacuum circuit breakers and others.

Domestic high-voltage vacuum circuit breakers have done well: Shaanxi Taikai high-voltage switch manufacturing: Shaanxi Pinggao intelligent electric. Hope it helps.

The top ten high-voltage vacuum circuit breaker brands are Shaanxi Taikai high-voltage switch manufacturing.

Domestic vacuum circuit breakers are all the same, from product accessories to assembly, are according to customer requirements. Take CHINT's VS1 as an example, it is exactly the same as what we do from the exterior to the internal accessories. But if you are greedy for small and cheap and buy low, it is all old for new, the unspoken rules of the industry, and the switch of the thrift market every day is dragged away by the manufacturer.

Another problem is the choice of vacuum tube, if the customer is willing to pay, we will choose Schneider Baoguang's vacuum tube, but the first pressure there, the difference in the price of a vacuum tube is hundreds, and the cost of a vacuum tube is more than 1,000. Wucheng Electric's vacuum circuit breaker can be disassembled to see, and the manufacturer's accessories can also be specified.

VSV series circuit breaker is Senyuan's main series, with a mechanical life of up to 30,000 times.

The difference between "circuit breaker" and "vacuum circuit breaker" is that the principle is different, the "vacuum circuit breaker" arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum, while the "circuit breaker" is not.

1. Circuit breaker.

Circuit breaker refers to a switchgear that can close, carry and break the current under normal circuit conditions, and can close, carry and break the current under abnormal circuit conditions within a specified time.

Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use, and the division of high and low voltage boundaries is relatively blurred, and generally more than 3kV is called high-voltage electrical appliances.

The circuit breaker can be used to distribute electric energy, start the asynchronous motor infrequently, protect the power supply line and the motor, and automatically cut off the circuit when they have serious overload or short circuit and undervoltage and other faults, and its function is equivalent to the combination of fuse switch and over/underheat relay. In addition, it is generally not necessary to change the parts after the fault current is switched off.

In the generation, transmission and use of electricity, power distribution is an extremely important link. The power distribution system includes transformers and various high and low voltage electrical equipment, and the low voltage circuit breaker is a kind of electrical appliances that are widely used.

2. Vacuum circuit breaker.

The vacuum circuit breaker is named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; It has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance for arc extinguishing, and is widely used in the distribution network.

Vacuum circuit breaker is an indoor power distribution device in 3 10kV, 50Hz three-phase AC system, which can be used for the protection and control of electrical equipment in industrial and mining enterprises, power plants and substations, especially suitable for the use of places requiring oil-free, less maintenance and frequent operation, and the circuit breaker can be configured in the central cabinet, double-layer cabinet and fixed cabinet as a control and protection of high-voltage electrical equipment.

Circuit breaker is an abbreviation of what people call pole circuit breaker. The circuit breaker is also a vacuum circuit breaker, and compared with ordinary vacuum circuit breakers, the material of the package is different. However, when it comes to a deeper level of technical issues, circuit breakers are very different from ordinary vacuum circuit breakers.

The circuit breaker is encapsulated by pouring epoxy resin outside the original vacuum bubble. Compared with the traditional assembled pole, the number of parts of the pole is greatly reduced, the structure is simple, the installation is convenient, the manufacturing process of the circuit breaker is simplified, and the reliability and stability of the circuit breaker are greatly improved.

Since the vacuum interrupter is embedded in the epoxy resin insulation material, it turns the original surface insulation into volume insulation, so it does not need to do any further treatment, and the solid sealing pole can achieve high dielectric strength, which is more conducive to the miniaturization design of circuit breakers and switchgears.

The vacuum interrupter and related conductive parts are embedded in the epoxy resin solid insulating material at the same time, shielding the influence of the external environment, and it is completely maintenance-free during the service life of the product, so that it has strong adaptability and can be widely used in various occasions such as chemical industry, metallurgy, mining, etc.

Although it is relatively expensive to produce, the main circuit in which the low-resistance vacuum interrupter and outlet seat are enclosed in epoxy resin improves the insulation level and anti-fouling ability, and eliminates the effect of condensation.

Circuit breakers are collectively referred to. It includes vacuum circuit breakers, such as high-voltage circuit breakers, leakage circuit breakers, molded case circuit breakers, small circuit breakers, composite circuit breakers, etc., all of which belong to circuit breakers, and circuit breakers generally play short circuit and overload protection functions. You can take a look here.

According to the different insulation properties, the vacuum circuit breaker is insulated by vacuum bubble, which has good insulation performance; Others, such as molded cases and frame circuit breakers, are air-insulated.

Circuit breaker is a general term, vacuum circuit breaker is one of the products, as well as molded case circuit breaker and miniature circuit breaker.
