Why does the street lamp controller trip after closing, and it is not short circuited with a multime

Is the gate too small? If the gate is sufficient, it is a place where there is leakage grounding.

Summary. The main reasons are as follows:

1. The switch is overloaded, and the rated current of the switch is not matched.

2. The fire wire on the load side of the switch is grounded, and the neutral line on the load side of the leakage switch is grounded, which will also cause tripping.

3. The switch is damaged or the electrical grounding is short-circuited, whether the neutral line on the load side is mixed with the neutral line of other circuits, and the line insulation is too low.

Leakage switch can not close normally inspection method:

1. Check whether the reset button of the leakage switch is reset. After pressing the reset button, it can be closed normally.

2. Check whether the wiring of the leakage switch is correct. incorrect and rewired.

3. Check the insulation of the line on the load side of the leakage switch, if it is short-circuited and grounded, it needs to be eliminated before it can be closed normally.

The 250W high-pressure sodium lamp of the street lamp is controlled by a leakage switch, and what is the reason for the jump when closing?

Hello, I have seen your question and am sorting out the answer, please wait for a while The main reasons for rubber grip are as follows: 1. The switch is overloaded, and the switch rated current selection does not match. 2. The fire wire on the load side of the switch is grounded, and the neutral line on the load side of the leakage switch is grounded, which will also cause tripping.

3. The switch is damaged or the electrical ground is short-circuited, whether the zero line on the load side is mixed with the zero line of other circuits, and the line insulation refers to too low as drafted. The leakage switch cannot be closed normally Check the method: 1. Check whether the reset button of the leakage switch is reset.

Press the reset button to close normally after filial piety. 2. Check whether the wiring of the leakage switch is correct. incorrect and rewired.

3. Check the insulation of the line on the load side of the leakage switch, if it is short-circuited and grounded, it needs to be eliminated before it can be closed normally.

There are ballasts and triggers that can be controlled with leakage switches.

The circuit breaker is closed, but the hopping light is on, does it affect the operation?

Hello dear <>

After the circuit breaker is closed, the width of the hole can affect the operation when the hopping light is on. The following are the possible causes and effects:1

The fault is not eliminated: the hop light is on to indicate that there is still a fault, which may be a problem such as circuit short circuit and overload. If the fault is not eliminated, the circuit may still not function properly after closing, or it may cause a more serious failure.

2.Signal error: The off-line light is on and may be caused by a signal error.

For example, after the circuit breaker is closed, the hopping light may light up due to a faulty signal line, faulty signaling device, etc. In this case, the hopping light is on does not indicate a problem with the circuit, but it needs to be troubleshooting. 3.

False Hopping: Sometimes the Hopping Light may have a false Hopping phenomenon, that is, the Hopping Light is on, but in fact the circuit is not faulty. In this case, the circuit can operate normally after closing, but it is necessary to confirm the reason why the hopping light is lit to avoid misjudging the fault.

No matter what kind of bright and bright key envy situation, the hopping light may affect the normal operation of the circuit. Therefore, it is necessary to confirm whether the fault has been eliminated or what is the reason for the hopping light to ensure the normal operation of the circuit before closing. At the same time, it is necessary to deal with faults in time to avoid affecting the safety and stable operation of the power system.

The street light switch trips and can't be closed, how to find the leakage point.

Hello coincidentally, your question Xiao Chai teacher has seen it is helping you query the relevant information and sort out the answers, please don't end the consultation when you see this message, the teacher is not a robot, you can add your own questions in this friend code time, I will answer it quickly

Hello, you can 1Use a switch without leakage protection to bury the external power supply, and the light with each phase of electricity is not lit is leakage 2Take off all the lanterns and check the line.

There is no shortcut to repair the street lamp, and it can only be checked one by one.

Summary. 1. What's going on with the electric switch always tripping.

1. Poor installation.

First of all, the first situation is caused by the poor installation of the electric switch, in the case of poor installation of the electric switch, the lead of each pile head will be loose, and with the passage of time, the fuse will soon be oxidized and burned off, resulting in undervoltage of the line, which will lead to the tripping of the electric switch.

2. Excessive power consumption.

If the actual electricity consumption of household appliances is too large, it will also cause the switch to trip, because the rated current of the line is fixed, if it exceeds it, it will automatically lose power if it cannot be loaded. In this case, we need to install a switch with the right amount of electricity used in the home so that it doesn't trip.

Sometimes the lights can be used, but after a while, the switch will trip, and the other lights will be turned off, but the negative main switch is old.

First, the electric switch is always tripping what is going on1, poor installation first of all, the first situation is caused by poor installation of the electric switch, in the case of poor installation of the electric switch, the lead of each pile head will be loose, with the passage of time, the fuse will soon be oxidized and burned off, resulting in undervoltage of the line, which will lead to the tripped of the electric switch. 2. If the actual power consumption of household appliances is too large, it will also lead to the tripping of the electric switch. In this case, we need to install a switch with the right amount of electricity used in the home so that it doesn't trip.

3. Leakage and short circuit, such as the leakage of the line in the house, or the leakage of the electrical appliances will also cause the line voltage to suddenly increase, so that there will be tripping. However, this situation is not easy to detect, so it is best to ask a professional electrician to check the electrical circuits and appliances in your home.

2. How to prevent the electric switch from always tripping 1. When using household appliances, we must pay attention to the fact that the load cannot exceed the rated current, otherwise it will easily cause tripping. Therefore, when making the tease used in a messy way, do not use high-power electrical appliances at the same time, when the load exceeds the normal range, it will cause the problem of mountain stalls. 2. To be reasonable wiring, when we choose the wire specifications, we must also choose according to its load, and we must not use overloaded wires, otherwise it is easy to trip later.

If the electricity consumption is relatively large, then it is necessary to choose a high-power wire.

What happens when the dual-control switch turns off the light? Encountered a strange problem, this light has been used for ten years, today when the light is turned off, suddenly the meter tripped, the switch can be closed in the state of the light, and the light is turned off and the ant tripped. Asking for an explanation?

Hello, glad to answer for you. Dual control switch is a commonly used lamp control method, which realizes the control of the same lamp through two switches in different positions of the barrage. When you have a short circuit when you turn off the lights, there could be several reasons:

1.Wire aging: If the wire is used for too long, it will wear and age, resulting in damage to the wire insulation and the possibility of short circuits.

2.Loose wiring: Dual control switches need to use two control switches and at least one light fixture together, if the wiring of one of the switches or lamps is loose or broken, it will also cause a short circuit.

4.Switch quality problems: The quality of the switch ribbon itself will also affect their durability and safety performance, if the switch quality is poor, it is easy to fail.

In the scenario you described, the meter trip may be due to a short circuit in one or more luminaires, resulting in excessive current, triggering a fuse power loss protection mechanism. It is recommended that you find an electrician to check and troubleshoot the fault to avoid safety accidents.
