Description
Technical field
The utility model relates to a kind of high voltage isolator.
Background technology
In power transmission and transformation system, the separating brake of isolating switch or earthed switch and combined floodgate are finished by operating mechanism.At present the operating mechanism of isolating switch all is by motor output basically, through multi-stage speed-reducing mechanism, is connected on the isolating switch driving shaft, and the rotating by motor realizes isolating switch deciliter.Running for distant place control motor, need secondary cable is caused control flow, deciliter aided location of isolating switch is finished by mechanical contact switch, the monitoring of its state also needs secondary cable is caused control flow, and concerning secondary control system, during the required isolating switch state of different devices, need state-detection position signalling cable is caused different places, so traditional switch operating mechanism secondary connection is very many, complex structure, reliability is low.And existing isolating switch can't be monitored the position of moving contact, can't understand the operation conditions of current isolating switch.
The utility model content
The purpose of this utility model provides a kind of high voltage isolator, to realize the monitoring to isolating switch moving contact position.
For achieving the above object, the technical scheme that adopts is, a kind of high voltage isolator, comprise moving contact, decide contact and controlling organization, controlling organization comprises drive motors and intelligent control unit, and drive motors is by the drive shaft moving contact, realize with decide contact deciliter, it is characterized in that on the driving shaft of described drive motors displacement transducer is installed, displacement transducer is connected with intelligent control unit.
Described intelligent control unit is provided with communication interface, and this interface is by the information communication of signal transmssion line or radio transmission apparatus realization and monitor terminal.
