Abstract
The utility model relates to an intelligent high-voltage cabinet with an up-down-linkage-structure valve, comprising a cabinet body, an upper valve and a lower valve, wherein fixed pulleys are respectively arranged on side plates at the right and left sides of the cabinet body; a first steel wire rope and a second steel wire rope respectively winds the fixed pulleys on the side plates at two sides, and are respectively coordinated with sliding of the fixed pulleys; one end of the first steel wire rope is fixedly connected with the left end of the upper valve; the other end of the first steel wire rope is fixedly connected with the left end of the lower valve; one end of the second steel wire rope is fixedly connected with the right end of the upper valve; the other end of the second steel wire rope is fixedly connected with the right end of the lower valve; two ends of the lower edge position of the lower valve are respectively provided with a valve draw bar; and the lower end of each valve draw rod is connected with the corresponding valve motion control mechanism in the cabinet body. The intelligent high-voltage cabinet with an up-down-linkage-structure valve is connected with the upper and lower valves through the steel wire ropes and the pulleys, and has the advantages of being simple in structure, being stable and reliable in motion, realizing synchronous motion of the upper and lower valves by only controlling the lower valve due to utilization of the upper and lower valve linkage, and simplifying a scissors board structure driving the valves.
Description
Technical field
The utility model belongs to the valve field of high-tension switch cabinet, relates to the valve telecontrol equipment that a kind of fixed contact high-tension switch cabinet blocks and exposes, and is specifically related to a kind of intelligent high-voltage board with linkage from top to bottom structure valve.
Background technology
Generally use high-tension switch cabinet and handcart type breaker to cooperate in the electric power system as electric control appliance; Its basic structure is exactly after the moving contact interlock of fixed contact and circuit breaker is set in switch cubicle, deciliter realization through circuit breaker to Circuits System deciliter.
And after circuit breaker was extracted switch cubicle out, the fixed contact in the switch cubicle possibly still have high-tension electricity, electric power operation and maintenance personal is had touch the fixed contact that has high-tension electricity, produced the possibility of Danger Electric shock risk.Therefore need realize cooperating when circuit breaker exposes fixed contact with the moving contact of circuit breaker when introducing the service position through valve system, valve falls automatically and blocks fixed contact after circuit breaker is drawn, and prevents to produce the possibility of touching electrified body generation Danger Electric shock risk.
The valve of present employing be mostly through circuit breaker when leading in/out, drive the switch cubicle both sides on the lower scissors plate structure, last lower scissors plate drives opening and closing of valve motion realization stationary contact head-room up and down respectively through connecting rod again.This structure up and down valve is controlled respectively, and so just feasible when circuit breaker and switch cubicle mismatch error are big, valve action is asynchronous up and down, opens the stroke different defects, and side scissors plate structure complicacy takes up room bigger.
The utility model content
The purpose of the utility model; Provide a kind of intelligent high-voltage board with linkage from top to bottom structure valve; This design can solve the valve control respectively up and down of present employing; Be easy to generate that up and down valve action is asynchronous, open the stroke difference, the side scissors plate structure complicacy bigger problem that takes up room.
The technical scheme that adopts is:
A kind of intelligent high-voltage board with linkage from top to bottom structure valve comprises cabinet, goes up valve and following valve;
Be respectively arranged with fixed pulley on the side plate of cabinet and arranged on left and right sides; First steel wire rope and second steel wire rope are walked around the fixed pulley on the side plate of both sides respectively; And be slidingly matched with fixed pulley respectively, an end of first steel wire rope is fixedly connected with the left end of last valve, and the other end of first steel wire rope is fixedly connected with the left end of following valve; One end of second steel wire rope is fixedly connected with the right-hand member of last valve; The other end of second steel wire rope is fixedly connected with the right-hand member of following valve, and the lower edge two ends of following valve are respectively arranged with the valve pull bar, and corresponding valve motion control mechanism links to each other in the lower end of valve pull bar and the cabinet.
Above-mentioned cabinet internal structure is known technology.
After last valve and following valve were fixed together through steel wire rope, steel wire rope was walked around fixed pulley, and the weight of last valve is designed to enough greatly; Purpose is for when upwards decontroling the valve pull bar; Can rely on the following valve of deadweight drive of valve to be synchronized with the movement, so just realize that following valve is directly by downward pulling when spurring the valve pull bar downwards; Open down the stationary contact head-room, will go up valve through steel wire rope simultaneously and be pulled upwardly and open the upper static contact chamber; Otherwise when upwards decontroling the valve pull bar, last valve falls by self gravitation and closes the upper static contact chamber, and valve moves upward and closes down the stationary contact head-room under driving simultaneously, has realized the valve structure of upper and lower valve synchronous interaction.
The advantage of the utility model is:
1, with pulley upper and lower valve is connected through steel wire rope, simple in structure, move reliable and stable.
2, adopt upper and lower valve interlock, action is synchronous and stroke is consistent.
3, only need control down valve can realize that upper and lower valve moves simultaneously, simplified the scissors plate structure that drives valve.
