High-voltage cabinet convenient for wiring

Abstract

The invention discloses a high-voltage cabinet convenient for wiring. The high-voltage cabinet comprises a high-voltage cabinet main body, a wiring assembly, a rolling door assembly, a ventilation andheat dissipation assembly, first connecting rods, a hanging ring and a door handle, wherein the wiring assembly is fixed on the inner wall of one side of the high-voltage cabinet main body; the rolling door assembly is fixed on the outer wall of the high-voltage cabinet main body on the other side of the wiring bottom plate; the ventilation and heat dissipation assembly is fixed on the inner wall, which is below the wiring side plate, of the high-voltage cabinet main body; and the first connecting rods are symmetrically in threaded connection with the outer wall of the top end of the high-voltage cabinet main body. According to the high-voltage cabinet, an instrument empty wiring scheme in the cabinet is adopted, BV6 plastic-covered copper wires are used for connection of the wires, lateral connection and reversed connection can be carried out, the wiring is convenient, and the reduction of the overall height of the high-voltage switch cabinet and the reduction of the manufacturing cost of a small bus are facilitated. In addition, the high-voltage cabinet does not occupy limited space when the cabinet door is opened by adopting the rolling door device, so that the space utilization rate is improved. The high-voltage cabinet further adopts the ventilation and heat dissipation device, so that the reduction of the temperature in the cabinet is facilitated.

[0002] High-voltage power distribution cabinets refer to electrical products that are used for on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption, and the voltage level is 3.6kV-550kV, mainly including high-voltage circuit breakers, high-voltage Isolation switch and grounding switch, high-voltage load switch, high-voltage automatic reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear, etc.; high-voltage switch manufacturing is an important component of power transmission and transformation equipment manufacturing Part, occupies a very important position in the entire electric power industry, but the existing high-voltage cabinet wiring method generally carries out wiring inside it, connects the external wires to the inside of the high-voltage cabinet, and then connects them to electrical components. The wiring is long and complicated, which is not conducive to the maintenance of the staff. Moreover, due to the replacement of the circuit breaker, the operating current of the small busbar decreases accordingly, and does not require such a large current. Moreover, the door of the cabinet generally adopts a double-leaf opening mode, so that when it is opened , takes up a lot of space, which is not conducive to the installation of high-voltage cabinets, and the ventilation and heat dissipation effect of the current voltage cabinets is not good, so that the electrical components work for a long time, and the temperature generated by themselves cannot drop, which may cause damage to the electrical components.
