Abstract
The utility model belongs to the technical field of a high -voltage electrical equipment technique and specifically relates to a 252kVGIS earthing switch is insulation system for moving contact, including casing, turning arm box, moving contact and joint, in the moving contact stretched out the casing and stretches into the turning arm box, its characteristic was connected through connecting to the moving contact with the turning arm: set up ground terminal and ground connection insulator between turning arm box and casing, ground terminal draws and works a telephone switchboard outside the moving contact, and the moving contact passes ground terminal and the ground connection insulator stretches into in the turning arm box. The utility model discloses a when being earthing switch mechanical characteristic test, can directly acquire the fracture signal, the signal is stable, characteristics that data are accurate.
Description
Technical field
The utility model relates to a kind of high voltage electric equipment technical field, specifically a kind of 252kVGIS moving contact of grounding switch insulation system.
Background technology
Moving contact is widely used in high voltage electric equipment, it plays a part separating brake or the combined floodgate of equipment, one of parts important in electric equipment, require that there is good mechanical performance and conductive performance, in traditional 252kVGIS earthed switch, ground connection moving contact and housing insulate by arranging insulating flange.This kind of version is when doing earthed switch mechanical characteristic test, earthed switch moves side part cannot directly obtain fracture signal, need get fracture signal, the fracture jitter that this mode obtains from earthed crank arm box side, and three-phase shares a fracture signal, is not easy to make mechanical characteristic test.
Summary of the invention
In order to overcome above-mentioned defect, the utility model provides a kind of moving contact insulation system, can realize when doing earthed switch mechanical characteristic test, and can directly obtain fracture signal, signal stabilization, data are accurate.
The technical solution adopted in the utility model is: a kind of 252kVGIS moving contact of grounding switch insulation system, comprise housing, Crankarm box, moving contact and joint, moving contact stretches out housing and extend in Crankarm box, moving contact is connected with connecting lever by joint, its feature: earth terminal and ground insulation are set between Crankarm box and housing, earth terminal is drawn and wiring outside moving contact, and moving contact extend in Crankarm box through earth terminal and ground insulation.
As a kind of preferred structure of the present utility model, described earth terminal is flange tubulose, monolithic construction is formed by body and ring flange, the ring flange of earth terminal is arranged on hull outside, body extend into enclosure interior, and ground insulation is the discoid of middle part band through hole, and ground insulation is separately positioned between earth terminal and Crankarm box and between earth terminal and housing, moving contact passes the through hole of body and ground insulation, extend in Crankarm box.
The utility model is ground insulation and earth terminal by the moving contact arranged outside of 252kVGIS earthed switch, ground insulation can be utilized to insulate to the outer setting such as housing and Crankarm box, the earth terminal ground switch that can achieve a butt joint is utilized to move side part when carrying out mechanical test, moving contact is directly measured, direct acquisition fracture signal, signal stabilization, data are accurate.
Accompanying drawing explanation
Fig. 1 is the utility model ground insulation minor structure schematic diagram.
Embodiment
Now by reference to the accompanying drawings the utility model is described further, Fig. 1 is one example of the present utility model, comprise housing 1, connecting lever 5 box 2, moving contact 3 and joint 4, moving contact 3 stretches out housing 1 and extend in connecting lever 5 box 2, moving contact 3 is connected with connecting lever 5 by joint 4, in the utility model, earth terminal 6 and ground insulation 7 are set between connecting lever 5 box 2 and housing 1, earth terminal 6 is drawn and wiring outside moving contact 3, and moving contact 3 extend in connecting lever 5 box 2 through earth terminal 6 and ground insulation 7.In the present embodiment, described earth terminal 6 is in flange tubulose, monolithic construction is formed by body and ring flange, the ring flange of earth terminal 6 is arranged on outside housing 1, it is inner that body extend into housing 1, and ground insulation 7 is the discoid of middle part band through hole, and ground insulation 7 is separately positioned between earth terminal 6 and connecting lever 5 box 2 and between earth terminal 6 and housing 1, moving contact 3 passes the through hole of body and ground insulation 7, extend in connecting lever 5 box 2.All be arranged with an independent earth terminal 6 outside each moving contact 3 in the utility model, get fracture signal for mechanical characteristic test and use.
Due to the utility model by moving contact 3 arranged outside of 252kVGIS earthed switch ground insulation 7 and earth terminal 6, outer setting such as ground insulation 7 pairs of housings 1 and connecting lever 5 box 2 etc. can be utilized to insulate, the earth terminal 6 ground switch that can achieve a butt joint is utilized to move side part when carrying out mechanical test, moving contact 3 is directly measured, direct acquisition fracture signal, signal stabilization, data are accurate.
The utility model is in order to keep moving contact 3 divide-shut brake invariant position, insulating case and insulation cushion can be installed additional between moving contact 3 and joint 4, use bolt is fixed, and makes moving contact 3 and joint 4 SI semi-insulation like this, reaches the object that moving contact 3 insulate with earthed crank arm 5 box 2.
As can be seen here, the utility model achieves when doing earthed switch mechanical characteristic test, can directly obtain fracture signal, signal stabilization, the accurate feature of data.
