Field high-voltage dielectric-loss test vehicle for power equipment

Abstract

The invention discloses a field high-voltage dielectric-loss test vehicle for power equipment, which comprises a chassis, a driving cab, and a rear carriage provided with a door at the tail of the rear carriage, wherein the rear carriage is divided into an operating control room for putting a variable frequency test power supply, a high-voltage dielectric loss tester, an operating platform and a control PC, and a test equipment room for putting an exciting transformer, a resonant reactor, a high-voltage standard capacitor, a compensating capacitor, a signal transfer box and auxiliary tools; and a testing platform which can be drawn out of the rear carriage by test equipment is arranged in the test equipment room, and the exciting transformer, the resonant reactor, the high-voltage standard capacitor and the compensating capacitor are arranged on the testing platform. When the vehicle of the invention arrives at a testing site, after the door of the rear carriage of the vehicle is opened and the testing platform is automatically stretched by a driving mechanism, test data can be obtained in a short time only by carrying out simple connection so as to complete the dielectric loss measuring task in a rated voltage at a time.
