Popis: For problems that high temperature caused by bad contact of isolator of mine-used high-voltage distribution equipment usually leads to faults and the faults are hardly detected, a design scheme of on-line monitoring system for temperature of isolator contact of mine-used high-voltage distribution equipment was put forward and software designs of lower computer program and on-line monitoring program based on LabVIEW of the system were introduced emphatically. The test result showed that the system can monitor temperature of isolator contact of mine-used high-voltage distribution equipment real-timely and remotely with error less than 1 ℃, which can meet requirement of actual project. Besides, the system has functions of fault diagnosis and early warning according to monitored temperature signal.
