Description
Technical field
The present invention relates to the valve mechanism on switchgear, the switch cabinet body and switch using the valve mechanism are further related to
Cabinet.
Background technique
Electric system at present operates with moveable high-voltage switchgear, the requirement of repair and maintenance, safe and reliable aspect is got over
Come higher.Existing shutter mechanism of switch cabinet mainly has common valve mechanism and two kinds of self-locking valve mechanism.Common valve mechanism and
Self-locking valve mechanism is upper and lower vertical mechanism, i.e., handcart push-on switch cabinet handcart from testing position to operating position when push away
Into or handcart exited from operating position to testing position when drive guide rod to move above and below by winning in succession above and below, that is, realize it is upper,
The opening and closing of lower valve, handcart can advance into operating position when valve is opened, when valve is closed in shielding contact box
Upper and lower static contact realizes that live part is isolated with handcart.
Common valve mechanism withdraw-type switch cabinet as disclosed in the Chinese patent that Authorization Notice No. is CN202353066U
Valve structure, including the firm banking that the cabinet body with switchgear is fixedly connected, be rotatably equipped on firm banking connecting lever and
Lower connecting lever, upper connecting lever and lower connecting lever pass through corresponding transmission connecting plate respectively and connect with corresponding valve.When handcart enters, handcart pressure
Dynamic upper connecting lever and lower connecting lever are rocked to open position, at this time upper connecting lever and the lower cross-shaped state of connecting lever, and reduction torsion spring stores up during being somebody's turn to do
Can, while driving the up and down valve being assemblied on valve guide plate to open by being driven connecting plate；When handcart exits, upper connecting lever and
Lower connecting lever corresponding valve self gravity and corresponding reduction torsion spring and under the action of open, move to close stance, valve closes automatically
It closes.
Self-locking valve mechanism vacuum circuit breaker switch as disclosed in the Chinese patent that Authorization Notice No. is CN204760852U
Cabinet valve opener, the mechanism are pin hole to be respectively set on upper connecting lever and lower connecting lever, and be correspondingly arranged two night bolts,
Night bolt connects lever by drawstring, and when handcart exits, night bolt is inserted into pin hole, prevents connecting lever from rotating, avoids valve
It is opened, when handcart enters, lever is depressed, and unlock is realized in abjection to night bolt out of pin hole under the affecting of drawstring.For another example
Authorization Notice No. is valve self-locking device for switch cabinet disclosed in the Chinese patent of CN201846002U, pulls slide plate by spring
Fixed upper and lower connecting lever prevents upper and lower valve plate from moving up and down.Self-locking valve mechanism has self-locking function, for moving back in handcart
Valve is limited when out to open, and there is certain anti-misoperation effect, improve security performance.
But power-off to inside contact box structure and static contact overhauled or replace static contact when, it is common living
Door machine structure needs outer power continuous action to keep valve in the open state, and it is outer again that self-locking valve mechanism will first release self-locking
Power continuous action keeps valve in the open state, could contact box inside and static contact be overhauled or be replaced static contact,
It is highly detrimental to installation, maintenance, the maintenance of static contact and its connection inside contact box of high-voltage switch cabinet.
Summary of the invention
