Abstract

The utility model discloses a vehicular variable-frequency resonant withstand-voltage testing apparatus which comprises a supply bay or a power box and a high-voltage rack. The apparatus is characterized in that unit components of the whole apparatus are divided into two parts, i.e., a power supply part mainly consisting of a variable-frequency power source and an exciting transformer and a high-voltage part mainly consisting of an electric reactor and an attenuator; the two parts are respectively fixed on two underframes to form the supply bay and the high-voltage rack, or the power supply part is installed and fixed in a container so as to form the power box and the high-voltage part is installed and fixed on one or two underframes to form the high-voltage rack. When the apparatus is to be used, the supply bay or the power box and the high-voltage rack are hung on a vehicle and respectively bound on the vehicle with one behind the other or are respectively bound on two vehicles; the supply bay or the power box and the high-voltage rack are not unloaded from the vehicle on site, wiring of systems is finished on the vehicle, and wires are led to an on-site power supply and a to-be-tested object so as to realize testing. Thus, convenience of on-site testing is improved through a simplest vehicular manner, work efficiency is enhanced, labor intensity is lowered down, and potential safety hazards are reduced.

Description

A kind of vehicular changing resonant withstand voltage testing device

Technical field

The utility model relates to the AC voltage withstand test complete equipment of power equipment, especially vehicular changing resonant withstand voltage testing device.

Background technology

Before electric system puts into operation or after the maintenance, all to test to the state of insulation of force device or equipment.Wherein, ac voltage withstanding is a basic and important test.Jumbo AC voltage withstand test complete equipment are huge numerous and diverse, and are all pretty troublesome from being shipped to the Assembling line.Along with the epoch are progressive, require in the industry testing equipment not get off to the scene, directly draw high pressure from car and test to test specimen, thereby the cry of increasing work efficiency, reduce labour intensity are day by day surging.

Summary of the invention

The purpose of this utility model is to provide a kind of vehicular changing resonant withstand voltage testing device, adopts the method short form test of prepackage and Integral lifting to prepare and power cut-off.For achieving this end, the utility model is divided into two parts to the unit block of package unit, namely take variable-frequency power sources and exciting transformer as main power unit with take reactor and voltage divider as main high-pressure section, be fixed on respectively and form power bay and high-pressure frame on two underframe, or power unit is fixed in the container forms power supply box, high-pressure section is fixed on one or two underframe forms high-pressure frame.Arrange binding before and after hanging on the car during use to power bay or power supply box and high-pressure frame, or hang on the two cars respectively and bind, do not unload to the scene, completion system line and going between can be tested to field power supply and test specimen onboard.So, increase the convenience of site test in the simplest vehicle-mounted mode, increase work efficiency, reduce labour intensity and reduce potential safety hazard.
