Abstract
The utility model discloses a vacuum circuit breaker cubical switchboard valve opening mechanism improves structure aims at providing a simple structure, convenient operation, safe and reliable's high tension switchgear valve opening mechanism. It including fix guide rail and guide bar in the cabinet body, establish between two guide bars last valve and down the valve, fix support in the cabinet body, articulate through two round pin axles on this support by last turning arm and down two scissors turning arms constituting of turning arm, respectively fix selling epaxial and do not fix torque spring on two corresponding turning arms, articulate last turning arm under and the short connecting rod between the valve and articulate under the turning arm and last valve between long connecting rod, fix the turning arm self -lock device in the cabinet is personally experienced sth. Part of the body, guide rail (16) below has lever (14), and this lever passes through the stay cord and is connected with turning arm self -lock device (8). The utility model discloses it is a high tension switchgear valve opening mechanism's improvement thoroughly to have avoided because of the potential safety hazard that the maloperation caused the accident.
Description
Technical field
The utility model relates to a kind of high-tension switch cabinet valve opener, particularly relates to a kind of high-tension switch cabinet valve opener modified node method.
Background technology
As everyone knows, high-pressure metal closed switch cabinet (KZN28-12) is generally made up of cabinet and handcart two large divisions.Circuit breaker in cabinet is installed on telescopic handcart, and fixed contact to be fixed in cabinet and to be connected with high-tension line; Generally be divided into two rows, connection or the disconnection of moving contact and fixed contact can be realized by advancing or pull out handcart.
At present conventional high-tension switch cabinet valve structure primarily of two slideways, be arranged on upper valve between two slideways and lower valve, be hinged on upper connecting lever in described cabinet and lower connecting lever by support, be fixed on bearing pin and two ends are separately fixed at torque spring on described two connecting levers, are hinged on short connecting rod between upper connecting lever and described lower valve, are hinged on the formations such as the long connecting rod between lower connecting lever and described upper valve, the connecting lever self-locking device be fixed in cabinet; Although fairly simple, all first must unlock connecting lever self-locking device during each operation, then handcart could be pushed, not only cumbersome, but also the potential safety hazard that there is misunderstanding lock and cause the accident.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model aims to provide simple, easy to operate, the safe and reliable vacuum breaker switch cabinet valve opener modified node method of a kind of structure.
To achieve these goals, the utility model is by the following technical solutions: it comprises and is fixed on two guide rails in cabinet and guide post, be located at the upper valve between described two guide posts and lower valve, be fixed on the support in described cabinet, by two hinge on this support by two scissors connecting levers forming of connecting lever and lower connecting lever, be separately fixed on described bearing pin and two ends and be separately fixed at torque spring on corresponding two connecting levers, be hinged on the short connecting rod between connecting lever and described lower valve, and the long connecting rod be hinged between lower connecting lever and described upper valve, be fixed on the connecting lever self-locking device in cabinet, have the lever be bearing in cabinet below guide rail, this lever is connected with connecting lever self-locking device by stay cord.
The below of lever has by the backing pin of Electromagnetic Drive; The both sides of upper valve and lower valve are respectively fixed with the pulley suitable with guide post.
Compared with the prior art, the utility model is owing to have employed technique scheme, lever is added in the below of guide rail, therefore connecting lever self-locking device is driven to unlock when handcart advances by stay cord, thus facilitate circuit breaker to open upper and lower valve by connecting lever and linkage, realize breaker closing.In addition, owing to adding by the backing pin of solenoid actuated in the below of lever, have the obstruction of backing pin in the power-off state, therefore handcart can not push combined floodgate; Thoroughly avoid the potential safety hazard caused the accident because of misoperation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A direction view in Fig. 1.
In figure: moving contact 1, upper valve 2, fixed contact 3, long connecting rod 4, lower valve 5, short connecting rod 6, guide post 7, connecting lever self-locking device 8, lower connecting lever 9, night bolt 10, support 11, electromagnet 12, backing pin 13, lever 14, handcart 15, guide rail 16, bearing pin 17, roll sleeve 18, upper connecting lever 19, pulley 20, torque spring 21.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Fig. 1 ~ 2: two guide rails 16 and two guide posts 7 are fixed in cabinet (not shown), between two guide posts 7, there are the upper valve 2 and lower valve 5 that can move up and down along this guide post; Support 11 is fixed with in described cabinet, two scissors connecting levers are hinged on this support respectively by bearing pin 17, each scissors connecting lever is made up of the upper connecting lever 19 be hinged on this bearing pin and lower connecting lever 9, upper connecting lever 19 and lower connecting lever 9 there is roll sleeve 18, torque spring 21 one end be enclosed within respectively on bearing pin 17 is fixed on connecting lever 19, the other end is fixed on lower connecting lever 9; Lower valve 5 is hinged with the upper connecting lever 19 of respective side respectively by the short connecting rod 6 being positioned at its both sides, and upper valve 2 is hinged with the lower connecting lever 9 of respective side respectively by the long connecting rod 4 being positioned at its both sides.Be fixed with connecting lever self-locking device 8 in cabinet, two night bolts 10 of this connecting lever self-locking device insert in the pin-and-hole of connecting lever 19, lower connecting lever 9 respectively.Have the lever 14 be supported on below guide rail 16 in cabinet, this lever is connected with connecting lever self-locking device 8 by stay cord.Connecting lever self-locking device 8 is traditional resilient pin device, and its concrete structure is eaten this again and repeated no more.
In order to more safe and reliable, there is the backing pin 13 driven by electromagnet 12 in the below of lever 14.
In order to ensure upper valve 2, lower valve 5 moves freely, is respectively fixed with the pulley 20 suitable with guide post 7 in the both sides of upper valve 2 and lower valve 5.
Operation principle: when handcart 15 advances to the right, lever 14 is depressed by handcart wheel, and two night bolts 10 of connecting lever self-locking device 8 are deviate from respectively and realize unlocking under the affecting of stay cord from the described pin-and-hole of two connecting levers; Meanwhile, handcart 15 moves on and touches the roll sleeve 18 of two connecting levers, thus promotes upper connecting lever 19 and rotate clockwise around bearing pin 17, promote lower connecting lever 9 and rotate counterclockwise around bearing pin 17; So, upper connecting lever 19 drive lower valve to move down by short connecting rod 6 and open, lower connecting lever 9 drives upper valve to move up by long connecting rod 4 and opens, realize closing a floodgate until moving contact 1 inserts in fixed contact 3.
When after device powers down, backing pin 13 stretches out because of electromagnet 12 dead electricity, thus hinders lever 14 to press down, and handcart 15 can not advance, and therefore can not close a floodgate.
