Abstract

The invention provides an integrated voltage regulating device. The device comprises a voltage regulator and a test voltage transformer which are integrated in a box body, the input end of the voltageregulator is connected with an external power supply, the output end of the voltage regulator is electrically connected with the input end of the test voltage transformer, the instrument end of the voltage regulator is electrically connected with the instrument end of the test voltage transformer, and the grounding end of the voltage regulator is electrically connected with the grounding end of the test voltage transformer; the grounding end of the voltage transformer is grounded; the high-voltage output end of the test voltage transformer is arranged on the outer surface of the box body, andthe high-voltage output end is used for connecting the test voltage transformer with the switch cabinet through a high-voltage test line. When voltages need to be applied to a 10kV switch cabinet oneby one to troubleshoot partial discharge points, only the high-voltage output end needs to be connected with the 10kV switch cabinet through the high-voltage test line, the wiring process of the high-voltage test transformer device is effectively simplified, and the troubleshooting efficiency of the partial discharge points of the switch cabinet is improved.

Description

technical field [0001] The present invention relates to the technical field of electric power equipment, and more specifically, to an integrated voltage regulating device. Background technique [0002] During the partial discharge live test during the operation of the 10kV switchgear, when the test value exceeds 40dB, it needs to be powered off. At present, the high-voltage test transformer device is mainly used to pressurize the 10kV switchgear phase by phase, and to check phase by phase and find the partial discharge point during the pressurization process. However, the fault location of the discharge point in the 10kV switchgear is unplanned and has the characteristics of uncertainty and contingency. If the high-voltage test transformer device is used to pressurize the discharge point to find the discharge point, there are the following disadvantages: the tester needs to work outside Five test wires are used to connect the voltage regulating box and the test voltage tran...
