Withstand voltage and error calibrating device for metering low-voltage current transformer

Abstract

The invention relates to a withstand voltage and error calibrating device for a metering low-voltage current transformer. The withstand voltage and error calibrating device for the metering low-voltage current transformer comprises a universal foundation platform (1), a supporting grounding module (2), a secondary wiring module (3), a primary guide clamping module (4) and a center penetrating mechanism (5), wherein the center penetrating mechanism (5) is arranged on the upper surface of the universal foundation platform (1), the secondary wiring module (3) is erected on the two sides of the center penetrating mechanism (5), the supporting grounding module (2) is arranged on the secondary wiring module (3), and the primary guide clamping module (4) is arranged on the upper surface of the universal foundation platform (1) and located beside the center penetrating mechanism (5). Compared with the prior art, the withstand voltage and error calibrating device for the metering low-voltage current transformer has the advantages of being simple in structure, flexible, reliable, high in universality and the like.

Description

technical field [0001] The invention relates to a device for checking current transformers, in particular to a device for checking insulation withstand voltage and error of low-voltage current transformers for metering. Background technique [0002] The current transformer used in the power grid is to reduce the large current in the primary line to the small current required by the secondary measurement circuit, and mainly realize the functions of electrical isolation and proportional measurement at both ends of the high and low voltage. The current transformer for metering is one of the main measuring instruments used in the settlement of electric energy trade, and it belongs to the national compulsory verification specification. Each metering current transformer needs to pass the initial verification and periodic verification before it can be used normally. [0003] On the existing current transformer verification assembly line, generally speaking, each detection station ...

Problems solved by technology

[0003] On the existing current transformer verification assembly line, generally speaking, each detection station is equipped with a corresponding matching detection device. Due to the large number of transformer detection items, multiple sets of different equipment are required for verification. When performing these verifications It takes a lot of time to manually connect and disconnect the wires, which has become the main bottleneck to improve the efficiency of transformer verification
