Abstract

The invention provides a gas insulation state simulation test device and a gas insulation state test method. The gas insulation state simulation test device comprises a bin, a heating element and a temperature detection unit; wherein a bin chamber is formed in the bin and provided with gas holes; the heating element is arranged in the bin chamber; the temperature detection unit is mounted on the bin and used for detecting the temperature of the heating element. Using the gas insulation state simulation test device can test decomposition products of insulating gases at a high temperature, and the insulation state simulation test device is capable of simulating real gas insulation equipment so as to directly apply test results to fault detection of the gas insulation equipment. During test, to-be-tested insulating gas is filled into the bin chamber through the gas holes, the heating element is enabled to heat, the temperature detection unit detects the temperature of the heating element, and the gas in the bin chamber is sampled for test through the gas holes at a preset temperature.

Description

technical field [0001] The invention relates to the field of electrical insulation, and more specifically, to a gas insulation state simulation detection device and a gas insulation state detection method. Background technique [0002] Sulfur hexafluoride gas is widely used as an insulating medium in electrical equipment such as GIS, circuit breakers, and transformers. These equipment are called gas-insulated equipment. At present, how to judge the internal insulation state of gas-insulated equipment is still a major technical problem, so it is of great significance to find an effective method to evaluate the internal insulation state of gas-insulated equipment. [0003] In the prior art, the insulation state of the gas-insulated equipment can be judged by analyzing the decomposition products of sulfur hexafluoride gas. By analyzing the decomposition products of sulfur hexafluoride gas, the method of judging the insulation state of gas-insulated equipment has the advantages...
