Background technique
Contact transmission is the indispensable structure of high voltage electric appliance, and in 110kV GIS tooling, bus mainly uses three
Phase common box bus, then A/B/C three-phase is closed by moving contact.The transmission of existing product moving contact mostly uses mechanism to pass greatly
Dynamic, design is complicated.Field test tooling requires small in size, is readily transported, while requiring easy to operate, often does one of them insulation
Test, in addition two phase ground, the frequent commutation wiring of test process needs are comparatively laborious.
After searching and discovering the prior art, existing mainstream producer uses the device of 110kV GIS three phase isolated test
Seldom, and internal drive structure is in technology blockage state, can not popularize use.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of contacts to move along a straight line
Drive mechanism.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of contact moves along a straight line drive mechanism, including moving contact, guide part and transmission shaft, is equipped in the guide part
Penetrating sliding cavity, the transmission shaft are moved back and forth across sliding cavity, and the moving contact is located at sliding cavity one end, moving contact
Place opposite with transmission shaft is flexibly connected, and the other end is connect with high voltage bus and insulation experimental provision；
When transmission shaft is connect with moving contact, moving contact movement is drawn by transmission shaft, to switch the test of high voltage bus
State.
Moving contact place opposite with transmission shaft is connected together.
Described moving contact one end is equipped with slot, and one end of the transmission shaft is equipped with pin, the pin and slot
Cooperation, after pin is aligned with slot and enters slot, transmission shaft rotation is stuck in pin in slot, transmission shaft can push away at this time
Pull contact movement.
The pin and transmission shaft interference fit connect.
The transmission shaft is connect with sliding cavity wall by rolling bearing.
The transmission shaft end is equipped with drawing pull bar, and the drawing pull bar is vertical with transmission shaft.
The drawing pull bar is bolted with transmission shaft.
The sliding cavity wall is embedded with sealing ring.
The sealing ring is y-type seal ring.
Compared with prior art, the present invention has the following advantages that：
(1) when transmission shaft is connect with moving contact, moving contact movement is drawn by transmission shaft, switches the test shape of high voltage bus
State mutually can arbitrarily switch between Earth Phase two states in test, while only need manual hand manipulation that can meet test
Process occupies little space without cumbersome patching operations, and structure is simple.
(2) moving contact place opposite with transmission shaft is connected together, and not additional components are easily operated.
(3) pin and transmission shaft interference fit connect, and pin is not easily to fall off.
(4) transmission shaft is connect with sliding cavity wall by rolling bearing, and when sliding rubs small, and stabilized structure, service life are long.
(5) drawing pull bar is set, force is facilitated；Drawing pull bar is bolted with transmission shaft, easy to disassemble.
(6) sliding cavity wall is embedded with y-type seal ring, increases robust motion, and frictional resistance is small, and resistance to pressure is good, is applicable in pressure
Power range is wide.
