Underground working condition environment simulation test system and test method

Abstract

The invention relates to an underground working condition environment simulation test system and a test method. The underground working condition environment simulation test system comprises a main box body, and a circulating air device, a refrigerating device, a pulverized coal generating device, a pulverized coal detecting device, an ultrasonic humidifying device and an integrated monitoring device which are arranged on the main box body. According to the underground working environment condition simulation system and the test method, various underground environments can be simulated in the same space; the precision of the pulverized coal generation and detection device is higher; the real-time monitoring system is arranged to more intuitively and effectively monitor the internal pulverized coal accumulation condition; the underground working environment condition simulation system does not need a heating device to balance the temperature in a low-temperature state, and is environment-friendly and energy-saving; the problems of low temperature and high humidity in the pulverized coal environment are solved.

Description

Technical field: [0001] The invention relates to the technical field of testing and testing of underground explosion-proof electrical appliances in coal mines, in particular to an environment simulation test system and a test method for underground working conditions integrating temperature, humidity and coal powder. Background technique: [0002] Downhole explosion-proof electrical equipment is a type of electrical equipment used in places with explosive gas and dust. It is a special equipment for underground working conditions that combines ordinary electrical equipment and explosion-proof performance. Under the influence of temperature change-humidity change-coal pulverized concentration and other coupling stresses under complex underground working conditions, the electrical reliability, durability and explosion-proof performance of explosion-proof electrical equipment will have complex effects different from those in ordinary environments. In order to study and test the ...

AI Technical Summary

Problems solved by technology

In order to study and test the influence of temperature, humidity and pulverized coal concentration changes on underground explosion-proof electrical equipment under the underground environment, it is necessary to solve the problem that the environmental simulation conditions are single and the space is generally small, and the underground equipment with larger volume cannot be tested; it needs to be solved The environmental simulation system cannot meet the limitations of simulating multiple underground environments in the same space; the test simulation is not realistic enough for underground mines, and the conclusions drawn from the test are not rigorous enough
