A self-supporting quick-installation impulse voltage generator and its installation method

Abstract

The invention provides a self-supporting and fast-installing impulse voltage generator and its installation method. The impulse voltage generator includes an impulse voltage generator stage module and a hydraulic system; the hydraulic system supports the impulse voltage generator stage by lifting the bracket modules, so that the impulse voltage generator level modules move in the vertical direction; the impulse voltage generator level modules are stacked and cascaded in sequence in the vertical direction under the force of the hydraulic system to form the impulse voltage generator body. The technical solution provided by the invention adopts a hydraulic mechanism to change the installation method of the traditional impulse voltage generator from top to bottom, and can realize the installation of the quick-mounted impulse voltage generator without the help of hoisting equipment; on the one hand, it can save the cost of the impulse voltage generator body The time and cost of installation and disassembly can reduce the requirements for on-site layout, and realize the on-site impulse voltage assessment of power equipment in a relatively small range.

Description

Technical field[0001]The present invention relates to an impact voltage generator and a mounting method thereof, specifically, relating to a self-reliable fast-stock impact voltage generator and its mounting method, which is provided in the field of high voltage test.Background technique[0002]In order to assess the insulation of the power equipment, the power equipment is required to compress the pressure test after the maintenance is completed, and the pressure resistance under the overvoltage and lightning overvoltage is an important part of the insulation performance of the equipment. The impact voltage generator is a major test device that generates an operation impact voltage and a lightning shock voltage. Since the power transmission engineering voltage has reached a high pressure level, the voltage tolerance level of the power equipment has been very high, and the voltage requirements of the test equipment are also very high. In order to carry out special high pressure level ...

AI Technical Summary

Problems solved by technology

Due to the complex conditions of the field equipment, the distance between the power equipment to be tested and the surrounding objects may be relatively close, and it is difficult to leave enough space for the lifting equipment and the impulse voltage generator, which brings great difficulties to the field test

At the same time, the parts of the impulse voltage generator lifted by the lifting equipment are transferred at a high altitude, there is a possibility of collision between the equipment to be tested and other devices, and there are potential safety hazards. In severe cases, the equipment will be damaged and cause failure, which will bring immeasurable economic losses.
