Abstract

The invention provides a switch cabinet alternating current and direct current voltage regulation test vehicle capable of being remotely controlled, which is characterized by comprising a voltage output circuit, a voltage output control circuit and a remote control circuit, wherein the voltage output circuit comprises a three-phase voltage regulator, wherein the input end of the three-phase voltage regulator is connected with a three-phase four-wire alternating current power supply after passing through a master air switch; the three-phase voltage regulator is provided with two output ends; one of the two output ends is a three-phase alternating current voltage regulating output end, and the other one is connected with a three-phase bridge rectifying and capacitor filtering loop and outputs adjustable direct current voltage, the voltage output control circuit is connected with the voltage output circuit through a relay; and the remote control circuit and the voltage output control circuit carry out control mode switching through a change-over switch. The test vehicle can save the time of an inspector, reduce the walking distance of the inspector when carrying out power transmissionat the test vehicle, debugging in front of the switch cabinet, and finally returning to the test vehicle for power-off, and the timely power-off of sudden conditions in the test process can be ensured.

Description

technical field [0001] The disclosure relates to the field of switchgear voltage regulation test, in particular to a remote-controlled switchgear AC and DC voltage regulation test vehicle. Background technique [0002] The switchgear voltage regulation test vehicle is the necessary equipment for the manufacturer to conduct power-on tests on various indicators of the switchgear before leaving the factory. It can provide various AC and DC power sources to test the switchgear. The power-on test of the switchgear often needs to manually open and close the power supply of each phase on the test vehicle, but remote control cannot be performed, and it is inconvenient to use. In order to save the time of the inspectors and reduce the walking distance of the inspectors from the test vehicle to the test vehicle for debugging, and finally to return to the test vehicle to cut off the power. It can also ensure a timely power outage in the event of an unexpected situation during the test...
