Description

Technical field: [0001] The invention relates to the technical field of verification of insulation testing equipment for electrical equipment, in particular to a verification device for a fully automatic high-voltage dielectric loss tester. Background technique: [0002] At present, the insulation structure of electrical equipment is composed of various insulating media. Due to the conductance of the media, the friction when the dipole rotates in the polar media, and the air gap discharge in the media, the media under high voltage (or The entire insulation structure) is lossy, and this loss is called dielectric loss, which is an important indicator of the insulation performance of electrical equipment. The dielectric loss tester is an automatic instrument for measuring dielectric loss tangent and capacitance. It can measure the dielectric of various insulating materials, insulating bushings, power cables, capacitors, transformers, transformers and other high-voltage equipmen...

Problems solved by technology

So far, the standard instruments for the domestic verification of dielectric loss testers are standard dielectric loss devices whose gears need to be manually switched. Every time a point is verified, the verification personnel need to enter the test area to switch to the next verification point. It is not only very cumbersome, but also there is a great potential safety hazard in frequent operations in the 10kV test area, which is obviously contrary to the spirit of our increasingly stringent safety production requirements, so all It is very necessary to develop the verification device of the automatic high-voltage dielectric loss tester
