Problems solved by technology

The disadvantage of this kind of distribution box is that the insulation performance is not good, and it will cause serious safety hazards when the line is short-circuited, and the product is relatively heavy and inconvenient to install.
In recent years, plastic distribution box shells have been developed, which have good insulation properties and are light in weight, but have poor mechanical properties, corrosion resistance and thermal conductivity, and cannot withstand large impact forces, nor can they be placed in the distribution box. Discharge of the heat generated during power-on may easily cause high temperature in the distribution box and bring potential safety hazards

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a community low-voltage power grid integrated distribution box and its application. Background technique [0002] The community low-voltage power grid connects various households and is related to people's quality of life, including components such as transmission cables, poles, and distribution boxes. The distribution box is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high-voltage switchgear, and then the low-voltage side of the transformer is stepped down to lead to low-voltage The distribution box and the low-voltage distribution box are connected to each power distribution panel, control box, and switch box. Inside, some switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices are ...
