Current Control of High Current Test for Explosion-proof Electric Apparatus

Based on the analysis of capacity and power characteristics of power supply network in coal mine underground, the explosion proof electric current protection performance test device is researched and developed. And, the flow control system is added in the device to improve the stability of the test current so as to improve the accuracy of the explosion proof electric current protection performance test, and to ensure the safety production of coal mine by using explosion proof electric apparatus.
