Background technology
China's power grid construction is quickly grown, and digital transformer substation becomes the hot spot built and studied, the intelligence of primary equipment
Change one of core woollen goods of digital transformer substation.For this particularly important Electric control of breaker and protection equipment,
Its intelligentized realization is of great significance, with the development and application of sensor technology, the intelligent functions of breaker
It is improved and perfect.
The displacement data for reading each phase moving contact of breaker can be facilitated using linear displacement transducer, and broken for vacuum
For the device of road, the structure size of vacuum circuit breaker is smaller, and usual manner installation linear displacement transducer is relatively difficult, needs to borrow
Special sensor installation seat is helped to realize the installation of linear displacement transducer.Existing sensor installation seat is as shown in Figure 1 and 2:
Including pedestal 1 and auxiliary slider 5, the fixed part of linear displacement transducer 2 is fixed on pedestal 1, and auxiliary slider is then installed on
The pedestal supporting surface 4 vertically extended, auxiliary slider tool are provided on the movable part of linear displacement transducer, on pedestal
There is the slider support face 6 being slidably matched with the support of pedestal supporting plane, pedestal supporting surface and slider support face are plane, are used
When, auxiliary slider is made to be connected with measured piece i.e. moving contact, when moving contact moves, straight-line displacement is driven to sense by auxiliary slider
The movable part synchronizing moving of device, so as to fulfill the measurement to moving contact displacement.Figure middle term 3 represents to realize auxiliary slider with moving
The connecting rod 3 that contact is synchronized with the movement.
Existing this sensor installation seat has problems in that:Breaker is when switching on and off acts, the shifting of moving contact
Dynamic is a reciprocating motion, and the stress point of auxiliary slider is different, such as breaker is in making process, auxiliary slider
Stress point is with regard to top, and breaker is during separating brake, and just on the lower, the difference of stress point causes auxiliary to be slided to the stress point of auxiliary slider
Block easily glances off, since slider support plane and the plane contact of pedestal supporting plane coordinate, the auxiliary slider pair after inclination
The force of linear displacement transducer and pedestal is uneven, and not only linear displacement transducer is fragile, and pedestal also deforms seriously, causes to slide
Block cannot neatly be synchronized with the movement with the movable part of linear displacement transducer, so as to be detached with measured piece, displacement be caused to survey
Amount distortion or even the switching on and off action for hindering breaker, cause breaker cannot normal divide-shut brake.
