The single - chip microcomputer control technology has been applied in the system to carry out monitoring and protective functions for the asynchronous motors controlled. combined with suitable peripheral interface, disposition and flexible software, the mcs can measure the current and voltage signals of the motors. based on the measurements, the computation, judgment and decision are made to implement the phase sensitive short circuit, overload, supply over - voltage, supply under - voltage, over - thermal, leakage lock - out and loss of phase protective function
系統採用單片機控制技術，完成所控制電動機的控制功能，並對所控制電動機的電壓、電流等信號進行檢測、計算、判斷和處理，實現短路、斷相、過載、欠壓、過壓、過熱、漏電閉鎖等保護功能，並提供本質安全型輸入、輸出介面，能與煤礦井下監測監控系統聯網運行。 -
According to the present actual underground power system which neutral point is grounded through arc suppression coil in many supper big shaft, the development history and present situation of synthetic protection system used in hv flameproof switchgear are reviewed, and on the basis of analyzing the problems existed in high voltage flameproof switchgear, the selective leakage protective method based on the detecting harmonic direction of zero sequence current as well as the value of zero sequence voltage is proposed in this paper, and at the same time, harmonics extracting schematic and transforming circuit are also designed
