Description

technical field [0001] The invention relates to the technical field of high-voltage equipment testing, in particular to a multifunctional high-voltage equipment safety performance testing device. Background technique [0002] With the progress and development of science and technology, high-pressure technology has been widely used in scientific research and industrial production. The working pressure of high-voltage equipment is very high, and the energy stored in the equipment is very large, which is extremely dangerous. As far as high-pressure equipment with liquid medium is concerned, the compressibility of liquid under high pressure is significantly improved, and the compression ratio is significantly increased. For example, the compression ratio of water at 1000MPa can reach about 20%, so the energy stored in high-pressure equipment is very large, which has great potential. potential danger, once a sabotage accident occurs, the consequences will be disastrous. Therefo...

Problems solved by technology

[0003] At present, most of the existing domestic high-voltage equipment performance testing devices and testing machines have relatively single functions, usually using manual operation, and cannot perform stress test analysis.

Chinese patent ZL99215552.5 provides an ultra-high pressure test station, which is composed of high-pressure pumps, valves, pressure gauges and pipelines, etc. It is used to measure the sealing and compressive strength of high-pressure equipment and parts. The system adopts manual operation. There is a single way of supercharging, and pulse supercharging operation cannot be realized. The system does not have an automatic control system, and functions such as overpressure automatic shutdown and unloading, data collection and stress test analysis cannot be realized.

Chinese patent CN200410155199.1 provides a pressure vessel hydraulic fatigue test system, which is a system specially used for pressure vessel fatigue test composed of oil circuit pressurization, pressure maintaining, pressure relief device and measurement control system, although computer Automatic control, but the boost rate cannot be adjusted, and the system does not have the functions of withstand voltage test and burst test

Chinese patent ZL93246639.7 provides a pressure testing machine, which is composed of a hydraulic control circuit, a pressure cylinder and a distribution valve. It is only used to test the compressive strength of the pressure-bearing equipment and cannot perform fatigue tests. The testing machine uses hydraulic oil as power source, the boost rate is relatively slow, manual operation is adopted, and automatic control cannot be realized
