Abstract
Provided is a manual interlocking mechanism of a locking device of a disconnector used for a high voltage switch cabinet. The defects that the conventional high voltage disconnector employs manual operation so that the operating force is large, the switching-on and switching-off are not in place, and the operation is complicated, time-consuming and labor-consuming are overcome, and the manual interlocking mechanism interlocked with an electric mechanism is provided to allow the disconnector of the high voltage switch cabinet to have an electric operation function. The manual interlocking mechanism is characterized in that a baffle is arranged at the inner side of a large bending plate via limit sleeves, pin shafts and torsion springs, the large bending plate is connected with a small bending plate via a connecting plate, the small bending plate is fixedly connected with an electromagnetic lock, the front end of an operation handle is provided with a keyway connected with an electric mechanism in a key manner, and when the manual interlocking mechanism is in use, the keyway at the front end of the operation handle is connected with a key at an end of a worm and gear deceleration transmission mechanism of the electric mechanism. The beneficial effects of the manual interlocking mechanism of the locking device of the disconnector used for the high voltage switch cabinet are that the interlocking of electric operation and manual operation is realized, the electric operation and the manual operation can both be performed, the operation is safe and reliable, the time and the labor are saved, the accuracy is high, the overhauling is convenient, and manual maloperation can be prevented.
Description
Technical field
The utility model belongs to high voltage electrical apparatus technical field, and the particularly operating means of indoor high-voltage isolating switch is a kind of manual interlocking device of the separation switch lock device for high-tension switch cabinet specifically.
Background technology
High voltage isolator is applicable to the power on/off of indoor high-voltage switch cabinet administration of power supply, be installed on indoor, for 7.2 ~ 40.5kV, in 50Hz three-phase alternating current single busbar connection or single busbar connection band bypath system and double-bus, accept and distribute electric energy, be mainly arranged in fixed type metal enclosing switch device.In prior art, high voltage isolator adopts operation manually, exist operating physical force large, point and not in place, complex operation and the defect that wastes time and energy; If switch is deciliter not in place when manual operation, to cause switch contact loose contact, after long-time transmission operation, exist the hidden danger that burns out high-tension switch cabinet, manual operation simultaneously also exists mistake and divides, closes by mistake the problem that causes major accident with on-load operation, therefore, along with the development of intelligent switchboard system, require the isolating switch of high-tension switch cabinet to possess electrically operated function, the manual interlocking device with the interlocking of motor drive mechanism interlocking need to be provided.
Summary of the invention
Technical problem to be solved in the utility model is, overcome the deficiencies in the prior art part, provide the one can electric operating, again can manual operation, and the interlocking of electric operating and manual operation interlocking, in order to realize a kind of manual interlocking device of the separation switch lock device for high-tension switch cabinet of isolating switch separating brake and closing operation.
The technical solution adopted in the utility model comprises large bent plate and operating grip, by stop collar, bearing pin and torsion spring, baffle plate is installed in large bent plate inner side, on large bent plate, connect little bent plate by connecting plate, on little bent plate, be fixedly connected with electromagnetic lock, be provided with at described operating grip front end the keyway being connected with motor drive mechanism key, when use, the utility model is connected by the key on the worm and gear reduction gearing mechanism termination on the keyway of operating grip front end and the motor drive mechanism of separation switch lock device.
Compared with prior art, the beneficial effects of the utility model are to have realized the interlocking of electric operating and manual operation interlocking, can electric operating, again can manual operation, and handling safety is reliable, and time saving and energy saving, accuracy is high, and maintenance is convenient, and can prevent manual misoperation.

Embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in FIG. 1 to 3, the utility model comprises large bent plate 1 and operating grip 8, by stop collar 2, bearing pin 3 and torsion spring 5, baffle plate 4 is installed in large bent plate 1 inner side, on large bent plate 1, connect little bent plate 6 by connecting plate 9, on little bent plate 6, be fixedly connected with electromagnetic lock 7, be provided with at described operating grip 8 front ends the keyway being connected with motor drive mechanism key.
As shown in Figure 4, when use, the utility model is connected with the cabinet panel of high-tension switch cabinet by connecting plate 9, the keyway of operating grip 8 front ends is connected with the key on worm and gear reduction gearing mechanism 10-1 termination on the motor drive mechanism 10 of the separation switch lock device of high-tension switch cabinet, rotating operation handle 8, the worm and gear reduction gearing mechanism 10-1 getting final product in driving electric mechanism 10 rotates.
When normal work, the cabinet panel that baffle plate 4 relies on torsion spring 5 to be close to high-tension switch cabinet blocks handle hole; Disconnect electromagnetic lock 7, electromagnetic lock 7 tapered ends are upwards lifted, and expose handle hole, and operating grip 8 puts in handle hole and coordinates with the worm shaft of worm and gear reduction gearing mechanism 10-1 front end, turn clockwise 40 circle isolating switches and close a floodgate, and turn counterclockwise 40 circles, isolating switch separating brake; Draw out operation handle 8, baffle plate 4 relies on torsion spring 5 to be close to cabinet panel and blocks handle hole, when normal isolating switch combined floodgate work, this baffle plate sealing, the electromagnetic lock of front end closes a floodgate and locks, and handle hole is blocked, operating grip 8 can not put in handle hole, thereby can prevent manual misoperation.
