Substation reactive voltage automatic control device

Abstract

The invention belongs to the field of reactive voltage automation. The invention relates to a transformer substation reactive voltage automatic control device. The outdoor temperature reaches-dozens of DEG C in winter in northern severe cold regions; electronic components in the VQC device can be changed due to low-temperature operation; the problem that normal use requirements cannot be met is solved; proposed now is the following scheme, the device comprises a device body, a first groove and a second groove are symmetrically formed in the inner wall of the device body, the first groove and the second groove are of a square structure, the structures of the first groove and the second groove are the same, a clamping groove is formed in one side of the inner wall of the first groove, and the clamping groove is disposed on the device body. The device is reasonable in structure, temperature transmission can be blocked through the heat insulation pad, so that normal work of the device bodyat a low temperature is guaranteed, and the power utilization safety of a transformer substation can be guaranteed; and meanwhile, the heat insulation pad can be rapidly disassembled, normal heat dissipation of the device body is prevented from being influenced at a normal temperature, and the use requirement is met.

Description

technical field [0001] The invention relates to the field of reactive voltage automatic technology, in particular to a substation reactive voltage automatic control device. Background technique [0002] A substation is a place in a power system that transforms voltage and current, receives electric energy and distributes electric energy. The substation in the power plant is a step-up substation. Its function is to boost the electric energy generated by the generator and feed it to the high-voltage power grid. The VQC device is often used in the operation of the substation. The basic function of the VQC device is to continuously sample the substation. Reactive power, power factor and voltage equivalent value during operation, and make a reasonable judgment based on this, automatically switch capacitor banks and adjust the gear position of the tap changer, so that the reactive power of the system is balanced on the spot, and the voltage is always at an appropriate setting. With...
