Abstract

The invention discloses an integrated test device and method for testing electrical performance of a voltage transformer for a distribution network, relates to the field of transformer performance test, and aims at solving the problems that electrical performance test for the voltage transformer for the distribution network in China cannot detect the transformer in a standard, intelligent and convenient way due to the defects that existing detection equipment are diversified and discrete, processes are complex, manual operation links are too much and the detection efficiency is low. Accordingto the integrated test device and method, only one set of equipment is used to complete test for key electrical performance of the voltage transformer, the test efficiency is high, the intelligent degree is high, and the test device and method are especially suitable for test of the voltage transformer of the distribution network.

Description

technical field [0001] The invention belongs to the technical field of voltage transformer performance tests, and in particular relates to an integrated test device and method for electrical performance tests of voltage transformers used in distribution networks. Background technique [0002] The voltage transformer for distribution network plays the role of high-voltage isolation and voltage transformation according to the ratio, and is used to provide voltage signals with an accurate proportional relationship with the primary circuit for electrical measurement, electric energy metering, and automation devices. At the same time, it is also used to provide signals and high-voltage isolation for instruments and relay protection, so the reliability, stability, and accuracy of voltage transformers for distribution networks play a vital role in the safe operation and marketing measurement of power systems. effect. [0003] Due to the low technical and capital thresholds of dist...
