Why does the knife trip? 5. Why does the knife trip?

If the load in the circuit is exceeded, such as a large power consumption, or if the circuit is short-circuited, the protection device of the switch will be activated and tripped.

If there is leakage in an electrical appliance or circuit, when a person touches the leaking circuit, the current enters the ground through the human body instead of the wires. In this case, the electrical switch acts as a protective device to protect the safety, resulting in tripping.

In short, the switch will trip to better protect the user, or to protect the appliance from damage. You need to troubleshoot the fault first, and then press the reset button of the switch to resume normal use.

1.In the process of using the knife, it is necessary to strictly follow the relevant requirements to ensure that the circuit current is within the working range and cannot exceed too much, otherwise the use will be limited.

2.Before pulling out or lifting the cutter, it is necessary to check the closed position of the switch. The operation can only be carried out after the number is checked.

3.Remotely operated knives cannot be operated manually in a live state, and the actual position needs to be checked after the operation is completed. If it is a phase-splitting control knife, you need to pull it to the middle phase first, and then to the edge phase.

4. Manual closing must be decisive and fast in operation, and pay attention to no impact at the end. Manual switching, to follow the slow, gear, slow process. And check whether the three phases are disconnected or closed at the same time, and make sure that the operating handle is locked and the tangent point is normal.

Where the current is large, or there is leakage, or there is a short circuit, check the line yourself

Like a human being, if you can't beat it, you have to run, if you can't eat, you have to stop it, it can't stand it, the current is too big, and it jumps.

If the current is too large, that is, where the electrical appliance that generates a large current is on or has a short circuit, try to unplug the electrical power that can be turned off and try again.

The original cause of the knife tripping: (1) overload. If the power consumption is too large or there is a short circuit, the protection device of the electric brake trips; (2) There is leakage of electrical appliances or lines, or people touch electricity, and the current is directly entered into the ground without the zero line, and the electric switch is aware of the leakage and the protection device trips.

In conclusion, tripping is to protect people and electrical appliances. After draining and debugging, the reset button must be pressed down to restore the original position.

There is a difference in answers, power outage refers to a sudden power failure and instantaneous call, power outage and power call occur almost instantaneously, power trip may cause damage to electrical appliances, trip is the safe operation of the traction power supply system that supplies power to the electric locomotive should be guaranteed. In the event of an accident, the relay protection device installed in the traction substation (opening and closing station, partition pavilion) will be activated by the short-circuit current generated by the accident, and the circuit breaker that supplies power to the accident point will be automatically disconnected, so as to reduce the scope of the accident and ensure the safe operation of other equipment and the normal power supply to the non-accident line. This action of automatically disconnecting the circuit breaker due to an accident is customarily called "tripping".

"Tripping" is commonly known as "tripping", that is to say, there will be an electric shock leakage protector in the place where electricity is used, when there is leakage or ** in some places, its current flow will become larger, and he will automatically cut off the total power supply to ensure safety. This is called "tripping".

Check the load and cable used, and then check the situation without load and switch.

It is advisable to check the relevant electricity terminals.

A short circuit means that the neutral wire and the live wire are directly connected together without passing through the electrical appliance. This fault phenomenon is to trip immediately after closing. Check the wires in your home for any damage to the insulation.

Overload is the use of electrical appliances that exceeds the rated current of the air switch The rated current is indicated on the electrical appliances How much is the working current of all the electrical appliances in the home Calculate whether the simultaneous use exceeds the rated current of the air switch Because not all electrical appliances are usually used at the same time, the rated current of the air switch is allowed to be slightly lower than the total current How much current will the electrical appliances that are often used at the same time If the rated current of the switch is exceeded, it must be replaced.

If the connection is connected at the connection of the switch, even if the current does not exceed the rated current of the switch, it will cause the switch to trip, please check and deal with it.

1) Overload. If the power consumption is too large or there is a short circuit, the protection device of the electric brake trips;

2) There is leakage of electrical appliances or lines, or people touch electricity, and the current is directly into the ground without the zero line, and the electric switch senses the leakage and protects the Xianyu slip device from tripping.

In conclusion, tripping is to protect people and electrical appliances. After troubleshooting, the reset button must be pressed to restore the original position. Brother.

The blade will not trip, nor can it be opened, if it encounters a short circuit, it will only blow the fuse, if the fuse is blown, there must be a short circuit.

Summary. Hello, we are happy to answer for you, the load in the circuit exceeds the standard, such as the power consumption is relatively large, or the circuit has a short circuit, then the protection device of the electric switch will be activated, and there will be a tripping situation. If there is leakage in the electrical appliance or circuit, when the person touches the leakage circuit, the current does not pass through the wire, but enters the ground through the human body.

All in all, the switch will trip in order to better protect the user, or to protect the appliance from damage. You need to troubleshoot the fault first, and then press the reset button of the electric switch to resume normal use.

Hello, we are glad to answer for you, the load in the circuit exceeds the standard, such as the power consumption is relatively large, or the circuit has a short circuit, then the protection device of the electric switch will start the number of cores, and there will be a tripping situation. If there is leakage in the electrical appliance or circuit, when the person touches the circuit of the leakage, the current does not pass through the wire, but enters the ground through the human body. All in all, the electric switch will trip, in order to better protect the user, or to protect the Tukai appliance from damage.

You need to troubleshoot the fault first, and then press the reset button of the electric switch to resume normal use.

The load in the circuit is excessive, such as the power consumption is relatively large, or the circuit has a short circuit, then the protection device of the electric switch will be activated, and the situation of tripping will occur. If there is leakage in the electrical appliance or circuit, when the person touches the leakage circuit, the current is not through the wire, but Qinghe enters the ground through the Yutong staring at the human body, in this case, the electric switch in order to protect the safety wheel spike, and play a protective device, the phenomenon of tripping. All in all, the switch will trip in order to better protect the user, or to protect the appliance from damage.

You need to troubleshoot the fault first, and then press the reset button of the electric switch to resume normal use.

Household appliances have short-circuit faults, frequent tripping is the first reason for leakage protection, is to check household appliances, if it has not been tripped, but now it is frequently tripped, it must cause enough attention to attack, at this time it should be a certain electrical appliance failure, but also collapse wheel is what we call the short circuit phenomenon, but the fault group letter is not obvious, but it also causes leakage, frequent tripping is leakage protection.
