householdCircuit breaker万彩网100线路Also known as household residual current circuit breaker, Weikewei Technology has summarized some common problems with household circuit breakers today, hoping to be helpful to you.

1、 How to solve the problem of tripping a household residual current switch when it thunders?

1. Due to rain, thunder, and humid air, the relative insulation performance decreases and the leakage current increases. As a result, the leakage protection system occasionally trips, and the rated safe leakage current of the leakage protection system is adjusted;

万彩网100线路 3. Reduce the power consumption of electrical loads;

4. Replace the relative leakage protector!

2、 Why does the leakage protector trip when the submersible pump is tripped?

Why does the leakage protector trip when the submersible pump is tripped? When electrical equipment experiences leakage, two abnormal phenomena occur: one is that the balance of three-phase current is disrupted, resulting in zero sequence current; Secondly, the metal shell that is not charged normally has a ground voltage (normally, both the metal shell and the ground are at zero potential).

3、 What is the reason why the leakage protector trips when connected to the neutral wire?

There are many reasons for the tripping of a leakage circuit breaker when it is connected to the neutral wire. That is to say, even if the circuit does not leak electricity, it is still possible that the circuit cannot be closed. Because the leakage switch does not have a brain, it does not know whether you are leaking water or electricity, it will only work according to its own principles.

4、 Why doesn't the leakage air switch have a neutral wire?

Why does the leakage air switch not have a neutral wire? There are two types of leakage protectors used in three-phase power circuits, three pole and four pole. Three pole is used for three-phase electrical appliances that do not require a neutral wire, while four pole is used for three-phase electrical equipment that requires a neutral wire.
