Entirely, play isolation voltage.In substation equipment maintenance process, need disconnecting switch moving to designated position realization electricity
The folding on road, thus disconnecting switch movement in place whether directly determine that can circuit normal operation.In view of substation line
Voltage is up to hundreds of kilovolts, and electric current maximum can reach tens kilo-amperes, and disconnecting switch movement is not in place to be caused equipment greatly
Damage, not only results in great economic loss, the major industrial accidents such as personal injury more likely occurs.
Currently, whether disconnecting switch is moved in place generally in such a way that motor signal judges cooperation eye-observation,
Judge whether disconnecting switch moves in place by the travel switch of motor rotation in mechanical actuation device, passes through human eye later
Observation carries out secondary-confirmation.This method there is a problem of larger in actual use：First, mechanical device itself exists
Various gaps, abrasion caused by processing, installation and long-time service, motor rotation angle can not with disconnecting switch movement angle
Reach fully synchronized, therefore will appear motor and be rotated in place and disconnecting switch the case where not moving in place, decision error rate is high；Its
