Description
Technical field
The present invention relates to a kind of switch cubicle and switch cabinet handcart and transmission mechanism for valve.
Background technology
It is due to handcart interchangeability, versatility preferably, in switch cubicle to use switch cabinet handcart in high-tension switch gear more.
Switch cabinet handcart type is more, relatively conventional such as circuit breaker cart, in use, circuit breaker cart is spread in advance along along switch cubicle
If good guide rail turnover switch cubicle, to meet normal experiment, job requirement.According to different voltage class and installation requirement,
Circuit breaker cart in switch cubicle is essentially divided on two major classes, the handcart moving direction and breaker of a kind of circuit breaker cart
Moving contact divide-shut brake direction is identical, if application publication number is the shifting disclosed in CN104917091A Chinese invention patent application
Open type ac metal closing switch gear, handcart moving direction and the moving contact division on breaker of another circuit breaker cart
Lock direction is perpendicular, as Authorization Notice No. for CN203617555U Chinese utility model patent disclosed in switch cubicle and its
Major loop structure.In fact, either which kind of form, to improve security performance, is provided with and static contact in respective switch cabinet
Corresponding valve, before circuit breaker cart is moved into place, static contact is closed in after valve, when handcart is moved into place,
Valve is opened, and the passage that the moving contact on breaker is formed after being opened through valve is contacted with static contact realizes closing operation, when
Moving contact separating brake and when handcart is exited, valve is re-closing off.
In the prior art, switch cabinet handcart and transmission mechanism for valve are realizing that the kind of drive that valve is turned on and off has company
The structures such as bar transmission, chain link transmission and gear connecting rod transmission.In gear drive, the active on switch cabinet handcart
Gear passes through the keying of corresponding transmission mechanism control valve as power intake.Applied when by this gear drive
When Authorization Notice No. is in the switch cubicle disclosed in CN203617555U Chinese utility model patent, circuit breaker cart level
Move into place, driving gear engages the driving force for being inputted to chain drive and forcing valve to be opened with driven gear, valve is opened
Open, the moving contact of breaker is moved up, with static contact grafting after the passage formed after being opened through valve, when needs will be disconnected
When road device handcart is exited, moving contact is moved down to be separated with static contact, and circuit breaker cart is displaced outwardly to exit switch cubicle,
Driving gear is separated with driven gear during circuit breaker cart is exited, and valve is closed.
In fact, engaged for this by driving gear with driven gear and for the type of belt drive of transmitting forces,
Because the axial direction of driving gear is consistent with handcart moving direction, when there are slight vibrations in handcart, the transmission of this gear engagement
, because driving gear movement causes Gear Contact part to be reduced, more there will be severe de- tooth, damaging gear easily occur in form
And the problem of axle, reduce transmission mechanism service life.
