What are the three major parts of Street Light Pole Top Box installation?

We know that family is a warm haven. Outside, household appliances also occupy a large part of our lives. When it comes to electricity, we can think of distribution boxes. What should the manufacturer pay attention to during the installation of Street Light Pole Top Box? Next, the Street Light Pole Top Box factory will explain the three major parts of distribution box installation:

1. Phase to phase short circuit, turn to turn short circuit or winding to core short circuit inside the Street Light Pole Top Box.

2. Oil level drops or leaks. The protection of power distribution box generally includes gas protection, pressure release protection and temperature protection.

3. Poor contact of tap switch or poor welding of wire. It can protect all kinds of faults in the Street Light Pole Top Box and can not fully reflect the faults of the distribution box. It needs to cooperate with the differential protection to complete the protection task of the distribution box. The distribution box manufacturer introduces the characteristics of pressure relief protection: when the pressure inside the distribution box exceeds the pressure relief device due to fault, the pressure relief device should also act to release the internal pressure to prevent explosion of the distribution box.

Here, the manufacturer of low-voltage distribution cabinet reminds users to know the characteristics of temperature protection: when the Street Light Pole Top Box is overloaded, the air cooler fails or when there is a fault inside the distribution box, the temperature of the distribution box will rise. When the temperature of the distribution box rises beyond the allowable range, the temperature protection device will alarm or trip to protect the distribution box.
