Description
Technical field
The present invention relates to a kind of switchgear and switch cabinet handcarts and transmission mechanism for valve.
Background technique
In high-tension switch gear, since handcart interchangeability, versatility are preferable, switch cabinet handcart is mostly used in switchgear.
Switch cabinet handcart type is more, relatively conventional such as circuit breaker cart, in use, circuit breaker cart is spread in advance along switchgear
If good guide rail passes in and out switchgear, to meet normal test, job requirement.According to different voltage class and installation requirement,
Circuit breaker cart in switchgear is essentially divided into two major classes, on a kind of handcart moving direction of circuit breaker cart and breaker
Moving contact divide-shut brake direction is identical, such as the shifting disclosed in the Chinese invention patent application that application publication number is CN104917091A
Open type ac metal closing switch gear, the handcart moving direction of another circuit breaker cart and the moving contact division on breaker
Lock direction is perpendicular, as Authorization Notice No. be CN203617555U Chinese utility model patent disclosed in switchgear and its
Major loop structure.Which kind of in fact, either form, to improve security performance, it is equipped in respective switch cabinet and static contact
Corresponding valve, before circuit breaker cart moves in place, static contact is closed in after valve, when handcart moves in place,
Valve is opened, and the moving contact on breaker passes through the channel formed after valve is opened and contacts realization closing operation with static contact, when
Moving contact separating brake and when handcart exits, valve is re-closing off.
In the prior art, switch cabinet handcart and transmission mechanism for valve have company in the kind of drive for realizing that valve opens or closes
The structures such as bar transmission, chain link transmission and gear connecting rod transmission.In gear drive, by the active on switch cabinet handcart
Gear passes through the opening and closing of corresponding transmission mechanism control valve as power intake.It is applied when by this gear drive
When Authorization Notice No. is in the switchgear disclosed in the Chinese utility model patent of CN203617555U, circuit breaker cart is horizontal
Mobile driving gear engages the driving force for forcing valve to be opened to chain transminssion mechanism input with driven gear in place, and valve is opened
Open, the moving contact of breaker moves up, after passing through valve and opening behind the channel that is formed with static contact grafting, when needing will to break
When road device handcart exits, moving contact is moved down to separate with static contact, and circuit breaker cart is displaced outwardly to exit switchgear,
Driving gear is separated with driven gear during circuit breaker cart exits, and valve is closed.
In fact, for this driving form for engaging transmitting forces with driven gear by driving gear,
Since the axial direction of driving gear is consistent with handcart moving direction, when there is slight vibration in handcart, the transmission of this gear engagement
Form is easy to appear causes Gear Contact part to be reduced because driving gear is mobile, and more serious will appear de- tooth, damage gear
And the problem of axis, reduce transmission mechanism service life.
