Test system of multifunctional gas-liquid state monitoring device and performance test method thereof

Abstract

The invention provides a test system of a multifunctional gas-liquid state monitoring device and a performance test method thereof, which belong to the technical field of simulation tests of power equipment monitoring devices. The test system comprises a tank body, the upper end of the tank body is connected with a cover body in a sealed mode, and a plurality of installation holes are formed in the tank body and can be used for installing sensors; the test system further comprises a heating assembly which is arranged at the lower end in the tank body, a temperature monitoring assembly which isarranged in the middle of the tank body, a gas-liquid regulation and control assembly which is arranged on the tank body and can be used for regulating the density of gas and / or the volume of liquidin the tank body, and a discharge simulation assembly which is arranged in the tank body and is used for simulating discharge in the liquid in the tank body; and the discharge simulation assembly cangenerate an electromagnetic field. The test system can be used for realizing an assessment test on an insulating medium, can be used for carrying out an insulating medium performance test, has the advantages of adjustable temperature, liquid level and gas density, capability of carrying out discharge simulation and simultaneously carrying out tests on precision, sensitivity and accuracy of varioussensors, and is convenient to install and move.

Description

technical field [0001] The invention belongs to the technical field of simulation tests of power equipment monitoring devices, and in particular relates to a system for carrying out simulation tests on power equipment insulation medium performance monitoring devices and a method for testing the test system. Background technique [0002] Power equipment is internally insulated by filling insulating gas, insulating oil, etc. With the long-term operation of power equipment in the system, the monitoring of insulating medium performance indicators is particularly important. At present, the pressure, temperature, micro-water content and oil content of insulating gas / liquid On-line monitoring devices for indicators such as gas content in the gas have been gradually developed, but there is a lack of simulation tests for monitoring devices. [0003] The monitoring device may be affected by pressure, temperature, and the state of the environment, resulting in large errors in the measu...
