真空接触器在煤矿井下的自动化运行中发挥着重要作用,在煤矿的安全生产中,由于真空接触器原因引起的故障在所有机电故障中占有很大比例,严重影响了煤矿的安全生产,同时也增加了投入成本,真空接触器的故障检测尤为重要,提出一种用于煤矿真空接触器的测试仪,并分析其组成结构及其工作原理。
Vacuum contactor plays an important role in the automatic operation of underground coal mine. In coal mine safety production, the failure caused by vacuum contactor accounts for a large proportion of all mechanical and electrical faults, which seriously affects the safety of coal mines. At the same time Increase the input cost, the vacuum contactor fault detection is particularly important, put forward a tester for coal mine vacuum contactor, and analyze the composition of the structure and working principle.
