Abstract
The utility model belongs to the high-voltage switchgear, relating to a middle-provided switch cabinet contact shade door control device, which includes a shade door component which is able to slide up and down on the guide post, a push rod which is arranged on the dolly of a circuit breaker and a transmission mechanism which is provided on the cabinet body. The transmission mechanism includes a pair of gears which are mutually joggled, namely a drive gear and a driven gear. An initiative arm is fixedly connected with the drive gear and able to rotate in the same axis. The end part of the initiative arm is arranged with a horizontal roller and the side of the roller is opposite to the front end of the push rod. The driven gear is fixedly connected with a passive arm. A connecting rod is provided between the passive arm and the shade door component. One end of the connecting rod is hinged with the shade door component and the other end is hinged with the end part of the passive arm. The utility model is provided with low cost, high movement reliability, compact structure and small spatial distance required by the movement.
Description
Technical field
The utility model belongs to high voltage switchgear, relates to a kind of intermediate switchgear cabinet contact cover door control device.
Background technology
Intermediate switchgear cabinet generally comprises one and can pass in and out the circuit breaker dolly of cabinet and be installed in the interior fixed contact of cabinet, and fixed contact is installed in the Contact Cover.When the circuit breaker dolly pushes service position in the cabinet, require the curtain door of Contact Cover to open automatically, the moving contact on the circuit breaker can be pegged graft with fixed contact, and when the circuit breaker dolly withdraws from cabinet, require contact cover door to close automatically again.The curtain controlling device for doors structure of existing intermediate switchgear cabinet Contact Cover is generally complicated, and cost is higher, and reliability is relatively poor, and in order to settle drive disk assembly, generally requires the spacing between the dynamic and static contact bigger, and this has just influenced the size and the layout of cabinet.
Summary of the invention
Technical problem to be solved in the utility model is, provides that a kind of cost is low, reliable in action height, compact conformation, intermediate switchgear cabinet contact cover door control device that the desired space length of action is little.
Intermediate switchgear cabinet contact cover door control device of the present utility model includes by a plurality of contact cover doors and combines as a whole and the curtain door assembly that constitutes, the curtain door assembly is installed on the vertical guide pillar, and can be on the guide pillar, lower slider, make the curtain door open or close Contact Cover, this device also comprises push rod that is installed on the circuit breaker dolly and the transmission mechanism that is installed on the cabinet, described push rod level is vertically fixed on the vehicle frame of circuit breaker dolly, it can move forward and backward with the circuit breaker dolly, described transmission mechanism includes a pair of pitch wheel, be driving gear and driven gear, there is a master arm to fixedly connected with driving gear, and can coaxially rotate, the roller bearing of a level is installed in the end of master arm, the front end of the above-mentioned push rod of side subtend of roller bearing, described driven gear is fixedlyed connected with a passive arm, and a connecting rod is arranged between passive arm and the curtain door assembly, one end and the curtain door assembly of connecting rod are hinged, and the end of the other end and passive arm is hinged.For further increasing the reliability of curtain door action, above-mentioned push rod, transmission mechanism and connecting rod can have two covers, and they are placed in the cabinet both sides respectively, simultaneously action.
The utility model is simple in structure, the reliable in action height; Because the stroke of curtain door lifting can recently be controlled by the transmission of master, driven gear, the circuit breaker dolly only need move than short distance and can realize the unlatching of curtain door or cut out, thereby can shorten the cabinet length of switch cubicle; In addition, because these device parts are few, and the overwhelming majority can adopt metal plate punching spare, reduced manufacturing cost.
Description of drawings
Fig. 1 is that the circuit breaker dolly is pushed into structural representation of the present utility model before the service position;
Fig. 2 is the view that the circuit breaker dolly is pushed into transmission mechanism behind the service position.
Embodiment
As shown in Figure 1, fixed contact 2 and Contact Cover 3 are installed on the cabinet 1 of switch cubicle, and a plurality of contact cover doors 4 are coupled to each other and constitute curtain door assembly 5, and the curtain door assembly can upper and lower slip on guide pillar 6, with opening and closing curtain door, its action is by push rod 7, transmission mechanism 8 and connecting rod 9 controls.
When needs curtain door is opened, circuit breaker dolly 10 moves forward, in moving process, push rod 7 front ends that are installed on the circuit breaker dolly withstand the roller bearing on the master arm 11 12 in the transmission mechanism 8, master arm 11 and driving gear 13 are turned clockwise, driving driven gear 14 and passive arm 15 is rotated counterclockwise, the connecting rod 9 hinged with passive arm 15 correspondingly moves up, drive curtain door assembly 5 and open the curtain door to maximum position, roller bearing 12 arrives on the top edge of push rods 7 at this moment, master arm 11 no longer rotates, roller bearing 12 can not fall yet, realize self-locking (as shown in Figure 2), and circuit breaker dolly 10 continues reach, make moving contact 16 enter Contact Cover 3 and peg graft to put in place with fixed contact 2;
In the time will withdrawing from circuit breaker dolly 10, move behind the dolly, after moving contact 16 left Contact Cover 3, roller bearing 12 also broke away from stopping of push rod 7, and this moment, curtain door assembly 5 freely fell under the effect of gravity, and the curtain door is closed, and whole device is returned to state shown in Figure 1.
In order to increase the reliability of curtain door action, push rod 7, transmission mechanism 8 and connecting rod 9 are provided with two covers, and they are placed in the cabinet both sides respectively, simultaneously action.
