Problems solved by technology

[0004] The purpose of the present invention is to design an operating device and its operating method for the opening and closing operation of low-voltage switchgear, which is used to effectively solve the problem that the existing low-voltage switchgear operating device for operating personnel cannot open and close the circuit breaker at one time. If the switch operation is in place, the circuit breaker cannot be opened and closed accurately, which may easily cause technical problems such as circuit breaker burnout and bus power loss.

Abstract

The invention belongs to the technical field of power equipment operation, and particularly relates to an operating device for switching-on and switching-off operation of a low-voltage switch cabinetand an operating method of the operating device. The operating device comprises an operating rod, a fixing pin and an operating base, wherein the operation base is composed of fixed side plates, a fixed front plate, a fixed lower plate, a fixing hole and a fixed top plate; the fixed lower plate and the fixed top plate are fixedly connected through the fixed front plate; the fixing side plates arefurther connected to the periphery of the fixing top plate, and the fixing hole is formed in the upper surface of the fixing top plate; a fixing nail is fixed on the operating rod; and the operating rod is inserted into the fixing hole in the upper surface of the fixed top plate through the fixing nail.

Description

technical field [0001] The invention belongs to the technical field of power equipment operation, and in particular relates to an operating device and an operating method for opening and closing operations of a low-voltage switch cabinet. Background technique [0002] Low-voltage switchgear is an important part of the power supply system of a nuclear power plant. In units 1, 2, 3, and 4 of the nuclear power plant, most of the low-voltage switchgears use MNS type switchgears. Due to the different loads, the capacity and volume of the low-voltage switchgear are also different, so the size of the circuit breaker in the switchgear is also different. For reasons of reasonable distribution and operational safety, large-capacity low-voltage switchgears are installed at the bottom of the entire row of switchgears, and in order to prevent the operating handles from contacting the ground, resulting in the inability to open and close the switchgears, large-capacity switchgears are equi...
