Mobile power-frequency contamination test power supply system

Abstract

The invention relates to a mobile power-frequency contamination test power supply system which is composed of a container, an operation table, a low-voltage switch cabinet, a voltage regulator, a power-frequency transformer, a protection resistor, a power-frequency voltage divider, and a power-frequency lead-out casing. The mobile power-frequency contamination test power supply system is characterized in that the requirement of mobile field test can be met by installing a power-frequency test power supply in the container, the container is of a design structure in which a container body and a container base can be separated, and the container body and the container base are fixed by 24 quick container buckling locks. According to the mobile power-frequency contamination test power supply system of the invention, a 50Hz power-frequency power supply is adopted to acquire high voltage, and the 50Hz power-frequency power supply has good quality and large capacity and can meet the requirement of contamination test research. A container movement design is adopted, so that rapid layout can be realized in a site to conduct test, and the workload of the site is reduced. The system can be powered by a generator, and can be used in regions without power supply.

Description

technical field [0001] The invention relates to a mobile power frequency power supply system for power frequency pollution test, which integrates power frequency test power into a container and belongs to the technical field of electric high voltage test. Background technique [0002] Power frequency test power supply is the main test equipment for power frequency AC withstand voltage test. AC withstand voltage is the most effective and direct method to identify the insulation strength of electrical equipment. It can judge whether the equipment can continue to operate, and also to ensure the insulation level of electrical equipment. An important means to avoid insulation accidents. The external insulation design of high-voltage power transmission mainly depends on two aspects, one is the problem of air gap, and the other is the pollution performance of the insulator under the working voltage. The external insulation problem of the line pollution is usually the key control f...

AI Technical Summary

Problems solved by technology

At present, the pollution external insulation test of insulators is usually carried out in the laboratory, through the simulation test of artificial pollution method, but there are still differences between this test and the natural situation, and the actual characteristics of different polluted areas cannot be verified.
