Distribution box manufacturerssaid,In recent years, with the rapid development of science and technology at the level of substation equipment, the demand for substation equipment is getting higher and higher. The distribution box manufactured by the distribution box manufacturer is an indispensable part of the substation equipment, and it is also very important to update and transform it. In order to adapt and facilitate the knowledge of electricity safety, the distribution box looks very important. All aspects of the distribution box must be improved. The improvement of the distribution box starts from the following aspects:

1. For the power transformer distribution box with volume of 100kV ± 6 ± 1A and above, the temperature control solenoid valve and axial flow fan shall be assembled on the left shell above the control electrical board at the outer side of the heat exhaust window in the box, so that the exhaust fan can be automatically operated to forcibly discharge the heat when the box reaches a certain ambient temperature.

2, the selection of short-circuit protection to avoid the distribution box power supply system when the external line fault. Select the intelligent phase loss protector with relatively small volume. For example, DA88CM-II motor phase loss protection module can be selected and installed in the distribution box to avoid burning the motor due to low voltage phase failure operation.

3. Improve the connection method of the power capacitor team of the original distribution box, and change its installation method from the pile cap on the DC contactor to the middle of the low voltage incoming line of the distribution box and the electric energy meter. Avoid errors in the measurement verification of the metering device due to the common failure of the power supply circuit of the power capacitor during operation or the destruction of the capacitor. In addition, the selected model and specification of power capacitors should be the main product of BSMJ to ensure the stable quality and safe operation of components.

4, distribution box should be how to achieve a good state, if the new column distribution equipment assembly platform, in the design of distribution box casing can choose 2mm thick stainless steel plate, and appropriate proportional distribution to enlarge the distribution box specifications (in the agricultural reform project used in the JP4-100/3W type premise, in the original shell total width direction specifications to expand about 100mm.

Distribution box manufacturersHint: Because the distribution box electric bakelite powder bakelite has problems such as large ductility, easy aging and easy cracking. The shell and stainless steel distribution box have major safety risks due to their poor insulation performance, easy corrosion and pipeline sealing level, resulting in electric shock injuries and frequent safety accidents. Accidents of home destruction and death caused by distribution box materials often occur, which leads to a large number of litigation cases and makes government departments very headache. Mainstream media have made many reports on such matters.

The potential safety hazards in the distribution box need to be inspected by themselves or by the maintenance staff of the residential area to prevent safety accidents such as fire accidents. Safe fire fighting and safe operation of the distribution box have safety protection for themselves and their families.
