Description

technical field [0001] The invention relates to the technical field of high-voltage measurement and detection, in particular to a fully automatic high-voltage transformer insulation withstand voltage test device. Background technique [0002] The demand for high-voltage transformers is increasing with the further expansion of the market, and the detection of high-voltage transformers is facing increasing pressure. At present, the detection methods for high-voltage transformers are inefficient and the management and control methods are backward, and a set of safe and effective centralized integrated control solutions has not been formed. In the industry at the present stage, the testing devices generally have problems such as single function, separate sets, and incomplete equipment configuration functions, which make it impossible to carry out all the tests required for the insulation withstand voltage test of high voltage transformers. In order to complete all the insulation...

Problems solved by technology

At present, the efficiency of the detection method for high-voltage transformers is low, and the management and control methods are backward, and a safe and effective centralized integrated control scheme has not been formed.

In the industry at the present stage, the testing devices generally have problems such as single function, separate sets, and incomplete equipment configuration functions, which make it impossible to carry out all the tests required for the insulation withstand voltage test of high voltage transformers. In order to complete all the insulation withstand voltage tests, it is necessary to equip various The detection device of the test needs to be manually transported between different detection equipment during the test, which will inevitably increase the cost of equipment purchase and labor costs

At the same time, switching between different tests requires manual disconnection of the wiring repeatedly, which inevitably increases the safety hazards of personnel operations and the test error rate caused by wiring deviations
