Is there a leakage protection or a circuit breaker in the main switch of the distribution box?
After a short circuit occurs in the home circuit, individual will take the initiative to disconnect to maintain the circuit insurance of the whole family. Leakage protection is leakage maintenance. After the human body contacts the leakage, it will take the initiative to disconnect and maintain the safety of the human body. There are two ways to open the main switch of individual distribution box with leakage maintenance. One is to use the circuit breaker with leakage maintenance function as the main switch. This 1p circuit breaker is used for air conditioners and individual sockets, so that no matter which line has a problem, the circuit breaker can directly maintain the home circuit. Moreover, if you always open it without leakage protection, you will feel that it does not have maintenance function. If there is a problem, you have to find the property to open the meter box control cabinet for you for troubleshooting. If you take the missing insurance, you may control it yourself.
1. Box body itself: the materials are distinguished from individual steel plates. We adopt steel plate. DC01 cold plate of Benxi Steel has high strength, is not easy to deform, and is not easy to have cracks during bending. There are thickness differences between steel plates. We adopt 1.0 standard cold-rolled steel plates. The steel plates also need to undergo pickling, phosphating, passivation, electrostatic painting, high-temperature baking and other process processes. These materials and processing processes determine the cost of the box;
2. Panel data: the materials used are new ABS plastics and modified plastics, as well as domestic and foreign manufacturers. The material and processing technology determine the panel cost; Our distribution box panel adopts imported engineering plastic ABS, which has good rigidity, high impact strength, heat resistance, low temperature resistance, excellent mechanical strength and electrical function, and good nominal luster. For many years, the current panel is still as bright as new.
- Double folding edge and bubble point process: double folding edge is adopted for the height and left and right of the distribution box. In order to save cost, some manufacturers usually only adopt high and low folding edge, which greatly reduces the firmness of the box and easily leads to the deformation of the box when the pressure is too high. The bubble point may make the box more firm, and the deformation caused by the impact of the box can be effectively reduced in the process of transportation. At the same time, the bubble point is also an examination of the bending process. If the bending fails, it will not be stuck, making the bending process more strict.
