Description
Technical field
The present invention relates to electric power facilities, especially easy replaceable GW16/17 type disconnecting switch movable contact spring.
Background technique
GW16/17 type disconnecting switch is common a kind of disconnecting switch in electric system, quiet during disconnecting link opening and closing
Feeler lever and movable contact spring will generate arc discharge during contact, it is often found that stationary contact bar and movable contact spring contact portion have obviously
The sign of ablation will significantly affect the electric conductivity of entire disconnecting switch after the partial ablation,
In maintenance, it can usually rotate stationary contact bar and change the relative position contacted with movable contact spring, ablating part is avoided to contact, and
Movable contact spring is then needed to disintegrate and dismantles entirely upper conductive arm and could replace due to being connected with Promotion From Within bar.
Current method has the following disadvantages and drawback:
1. GW16/17 type disconnecting switch used at present, whole movable contact spring has silver coating, but contact point only has a point, such as
Scaling loss at fruit is single then needs to replace whole movable contact spring, can not use other positions.
2. replacement movable contact spring needs body disassembly entirely upper conductive arm, take a substantial amount of time, and dismantle and return and load onto conduction
It is more that arm is related to part, has higher technical difficulty, it is unreliable that installation fault will lead to disconnecting link work
In view of the deficiencies in the prior art, technical problem to be solved by the invention is to provide a kind of easily replaceable GW16/17 type every
Pass movable contact spring is left, the upper conductive arm of disconnecting link is unloaded without disassembling body, can be replaced by simple means, it is not only reasonable in design,
And it is efficiently convenient.
Summary of the invention
The present invention proposes easily replaceable GW16/17 type disconnecting switch movable contact spring, can when movable contact spring generates ablation fast velocity modulation
Whole movable contact spring position or replacement movable contact spring.
The present invention uses following technical scheme.
Easy replaceable GW16/17 type disconnecting switch movable contact spring, the switch movable contact piece (6) include movable contact spring pedestal (1), lead
Electric piece (2), conductive strips (3)；The movable contact spring base position is equipped with multiple bolts hole；The conductive sheet is removably solid with fastener
At movable contact spring bolt of lower base hole (7)；Fixed bit of the conductive sheet on movable contact spring pedestal can be connected by change conductive sheet
The bolt of lower base hole that connects adjusts.
The spiral shell connecting with striking fingertip (4) and lift lever (5) is respectively arranged at the top and bottom of the movable contact spring pedestal
Keyhole.
The cross section of the movable contact spring pedestal and conductive sheet is U-shaped, and the conductive sheet of the U-shaped is placed on the dynamic touching of U-shaped
On piece pedestal.
The fixed bit that three bolt of lower base holes form conductive sheet is respectively equipped at the two sides of the movable contact spring the middle of the base.
The conductive strips are flexible circuit；Bolt hole is equipped at the top of conductive strips.
The movable contact spring forms electric interface with the silver coating on surface；When the scaling loss position of scaling loss at single occurs in electric interface
When, it prevents from being in electrical contact in scaling loss position by adjusting fixed bit of the conductive sheet on movable contact spring pedestal.
When the scaling loss position of many places scaling loss occurs in electric interface, prevent from connecing in scaling loss position progress electricity by replacement conductive sheet
Touching.
Compared with prior art, the invention has the following advantages: in disconnecting switch maintenance, without disintegrating in disassembly
Conductive arm only needs the relative position for changing changeable type conductive sheet and movable contact spring pedestal for the first time, can be solved because contact surface is burnt
The problem of erosion causes disconnecting link electric conductivity to decline, again after ablation, it is only necessary to dismounting and change changeable type conductive sheet part, it is high
It is convenient to imitate, can effectively save maintenance cost, have broad application prospects.
