Low-voltage capacitance compensating cabinet

Abstract

The invention relates to a low-voltage capacitance compensating cabinet, which comprises a stand body consisting of a plurality of stands. The left side stands and the right side stands are respectively provided with a plurality of beams every certain distance from the top to the bottom. The rear side stand is provided with a core plate which is equipped with a bended copper bar connected with an incoming line knife fuse. A drawer-type module of the core plate is provided with a capacitor with certain capacity, an electric reactor, a contactor or a thyristor switching module, a vertical busbar and a fuse. The modules are connected with each other by special bus clampers. The low-voltage capacitance compensating cabinet can conduct the modularized design on the structures such as the capacitor, the electric reactor, the contactor or the thyristor switching module, the vertical busbar, the fuse and the like arranged in the cabinet with the guarantee of the performance of the capacitance compensating cabinet; compared with the traditional fixed arrangement, the capacity of the single cabinet can be improved by at least one time, and the cabinet can be easily matched with various cabinets of different types and can generate various capacities and progression according to the needs; and the maintenance and the updating of the cabinet are convenient and safe.

Description

technical field [0001] The invention relates to a power distribution cabinet, in particular to a low-voltage capacitor compensation cabinet. Background technique [0002] In the prior art, some low-voltage filter compensators are mainly composed of electronic components such as reactors, switching units, unit fuses, and knife fuses. Among them, the reactors, switching units, and unit fuses are arranged in multiple groups. And installed in a fixed distribution cabinet. The cabinet body of this type of power distribution cabinet is usually hollow and rectangular. There are cabinet doors at the front and back of the cabinet body, which are the front cabinet door and the rear cabinet door respectively. The switching unit, reactor and knife fuse switch are placed in layers, and the reactor It is set above the switching unit and the unit fuse, and the knife fuse switch is set near the top of the cabinet, but the distribution of each floor of this power distribution cabinet is rel...

AI Technical Summary

Problems solved by technology

The cabinet body of this type of power distribution cabinet is usually hollow and rectangular. There are cabinet doors at the front and back of the cabinet body, which are the front cabinet door and the rear cabinet door respectively. The switching unit, reactor and knife fuse switch are placed in layers, and the reactor It is set above the switching unit and unit fuse, and the knife fuse switch is set near the top of the cabinet, but the distribution of each floor of this power distribution cabinet is relatively tight, which may easily lead to poor working conditions of the switch

Therefore, the capacitors, reactors, contactors or thyristor switching modules, vertical busbars, fuses, etc. inside the existing low-voltage capacitor compensation cabinet are all installed in a distributed manner. very messy and unsightly
