Abstract

The invention discloses a comprehensive transformer testing system which comprises an insulation resistance tester, a voltage ratio and connection group test, a direct-current resistance test, a no-load loss and no-load current percentage test, a load loss and short circuit impedance percentage test, an induction voltage withstand test and a power frequency withstand voltage test, wherein the insulation resistance tester can measure insulation resistance values. A PLC is adopted as a core control device, and stable test operation software is adopted, and the operation is simple and convenient.The PLC is adopted as a core control device, stable test operation software is adopted, the operation is simple and convenient, and the CT/ PT does not need to be manually shifted, and voltage and current are automatically tested and monitored. Lifting speed can be automatically adjusted according to the magnitude of the voltage and current. The temperature rise test of a transformer adopts a wireless temperature sensor, and the temperature rise change is automatically monitored, the temperature is recorded in real time, the test circuit is simplified, and the transmission efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of transformer equipment, and in particular relates to a transformer comprehensive testing system. Background technique [0002] With the development and progress of science and technology, automation technology is becoming more and more mature. Traditional manual transformer testing equipment can no longer meet the social needs of high efficiency, and automated testing systems are highly recommended by users. [0003] However, in the field test and use, the usual transformer comprehensive test system still has problems such as low automation level, prominent equipment operation safety problems, accident analysis and operation system are limited by technical conditions, etc., which raises the user's technical requirements for operators and running costs. Contents of the invention [0004] The purpose of the present invention is to provide a transformer comprehensive testing system to solve the problems r...
