Abstract
The utility model relates to a secondary plug interlocking device of a central-positioned switch cabinet. The device comprises a secondary dynamic plug connected on a breaker handcart and a secondary static plug fixed on a cabinet body, and the secondary static plug is installed on the sidewall of the cabinet body sideward the breaker handcart; the sidewall of the cabinet body is fixedly provided with a guide groove, and a guide rod can swing up and down in the guide groove; a rear end of the guide rod is connected with a baffle plate; when the rear end of the guide rod swings upwardly, the baffle plate can shield the front of the secondary static plug; when the rear end of the guide rod swings downwardly, the baffle plate can escape the front of the secondary static plug; a front end of the guide rod is hinged to an upper end of a swing arm, and the center of the swing arm is hinged to the cabinet body; an extension spring is connected between an upper segment of the swing arm and the cabinet body, and an extension spring force can drive the upper segment of the swing arm to swing forwardly; and one side of the breaker handcart is provided with a driver board, and the driver board can drive a lower end of the swing arm to enable the upper segment of the swing arm to move backwardly when the breaker handcart moves from a test position to a work position. The secondary plug interlocking device is simple in structure and reliable in interlocking and improves the operation reliability.
Description
Technical field
The utility model relates to a kind of parts of middle high-pressure switchgear, specifically a kind of intermediate switchgear cabinet secondary plug interlock.
Background technology
In the intermediate switchgear cabinet, circuit breaker cart can or shift out at cabinet middle part shift-in, on the handcart except circuit breaker is set and be used for moving contact that the cabinet upper static contact cooperates, also be provided with the moving plug of the secondary that connects by cable, the moving plug of secondary can be pegged graft with the quiet plug of secondary that is arranged in the cabinet, realizes the connection of secondary circuit.Handcart has test position and service position in cabinet, operator or the moving plug of secondary is inserted on the quiet plug of secondary when test position operates and do not allow that when handcart moves forward to the service position from test position after the dynamic and static plug of secondary is carried out plug.In the existing intermediate switchgear cabinet, the secondary static socket is arranged on the cabinet wallboard in handcart the place ahead usually, when handcart is positioned at the service position, because stopping of handcart car body can't plug operation to the dynamic and static plug of secondary, thereby realizes interlocking.But the defective that this structure exists is: because the quiet plug of secondary is positioned on the traffic direction of handcart, after the moving plug of secondary inserted, the dynamic and static plug of the stube cable of secondary plug and secondary all easily because the movement of handcart damages, had affected the reliably working of equipment.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of simple in structure, easy to operate, intermediate switchgear cabinet secondary plug interlock that reliability is high is provided.
Intermediate switchgear cabinet secondary plug interlock of the present utility model includes by cable and is connected to the moving plug of secondary on the circuit breaker cart and is fixedly mounted on the quiet plug of secondary on the cabinet of switch cubicle, and described secondary is quiet to be installed on the cabinet sidewall of circuit breaker cart side at hand; Be fixedly installed a guide groove with parallel sidewalls on the sidewall of described cabinet, guide rod passes guide groove and can swing up and down in guide groove; Described guide rod rear end is connected with a baffle plate; Baffle plate can block the front of the quiet plug of secondary when the guide rod rear end upwards swings, and the moving plug of secondary can't be plugged; When the guide rod rear end during to lower swing baffle plate can avoid the front of the quiet plug of secondary, the moving plug of secondary can be plugged; Described guide rod front end is hinged on the upper end of a swing arm, and the swing arm middle part is hinged on the cabinet; Be connected with an extension spring between swing arm epimere and the cabinet, extension spring power can spur the swing arm epimere and swing forward; Described circuit breaker cart one side is provided with a drive plate, and the lower end that described drive plate can drive swing arm when circuit breaker cart was moved to the service position by test position swings the swing arm epimere backward.
Described drive plate has the confined planes of a level and is positioned at the downward-sloping guiding incline of confined planes front end, and the lower end edge guiding incline that moves forward swing arm described in the process at circuit breaker cart is moved upwards up on the confined planes, and the swing arm epimere is swung backward.
The utility model is simple in structure, interlocking is reliable, because the quiet plug of secondary is arranged on the cabinet sidewall, after the quiet plug plug of secondary is pegged graft, be difficult in the circuit breaker cart moving process the dynamic and static plug of secondary and stube cable are produced damage, improved reliability of operation.

Embodiment
As shown in the figure, this intermediate switchgear cabinet secondary plug interlock includes by cable and is connected to the moving plug of secondary on the circuit breaker cart and is fixedly mounted on the quiet plug of secondary on the cabinet of switch cubicle, and described secondary is quiet to be installed on the cabinet sidewall of circuit breaker cart side at hand; Be fixedly installed 3, one guide rods 4 of guide groove with parallel sidewalls on the sidewall of described cabinet and pass guide groove 3, and can in guide groove, swing up and down; Guide rod 4 rear ends are connected with a baffle plate 5; The front that baffle plate 5 can block the quiet plug of secondary when guide rod 4 rear ends upwards swing can't plug the moving plug of secondary; When guide rod 4 rear ends during to lower swing baffle plate can avoid the front of the quiet plug of secondary, the moving plug of secondary can be plugged; Guide rod 4 front ends are hinged on the upper end of a swing arm 6, and swing arm 6 middle parts are hinged on the cabinet; Be connected with an extension spring 7 between swing arm 6 epimeres and the cabinet, extension spring power can spur swing arm 6 epimeres and swing forward; Circuit breaker cart one side is provided with a drive plate 8, and the lower end that described drive plate 8 can drive swing arm 6 when circuit breaker cart was moved to the service position by test position swings the swing arm epimere backward.
When circuit breaker cart was in test position, as shown in Figure 1, the effect of extension spring 7 swung forward swing arm 6 epimeres, drove guide rod 4 rear ends to lower swing, made baffle plate 5 avoid the front of the quiet plug of secondary, and the moving plug of secondary can insert;
When circuit breaker cart moved forward to the service position, as shown in Figure 2, drive plate 8 drove swing arm 6 and swings backward, drives guide rod 4 rear ends and upwards swings, and makes baffle plate 5 stop the dynamic and static plug of the secondary of having pegged graft, and it can not be plugged, and realizes interlocking.
Drive plate 8 has the confined planes 9 of a level and is positioned at the downward-sloping guiding incline 10 of confined planes front end, and the lower end edge guiding incline 10 that moves forward swing arm 6 in the process at circuit breaker cart is moved upwards up on the confined planes 9, and swing arm 6 epimeres are swung backward.
