Abstract
The utility model discloses a kind of electromagnetic interlock device, and the operating grip of on-load switch is other is provided with electromagnetic lock, and electromagnetic lock is connected with on-load switch, on-load switch closes a floodgate, and electromagnetic lock is energized, then the intrinsic blocking lever of electromagnetic lock stretches out, run through the groove of operating grip hollow, lock operation handle zero rotates.The utility model has the advantages that easy for installation, simple to operate, safe and reliable; Not only economize on resources, greatly reduce workload, and highly versatile, in all types of on-load switch that can be used for dissimilar high-tension switch cabinet and isolating switch.
Description
Technical field
The utility model relates to a kind of interlock, particularly a kind of for the on-load switch of high-tension switch cabinet and the electromagnetic interlock device of isolating switch.
Background technology
For High-voltage Incoming Cabinet, the existing obvious cut-off point of on-load switch, system load current under normal circumstances can be cut-off again simultaneously, have connecting-disconnecting function large, safe and reliable, the life-span is long, can frequent operation, the features such as few maintenances, but for " five anti-interlockings " requirements mistake drawing switch and mistakenly entering charged chamber then there is no good solution, this is the place of needs improvement.
Utility model content
Technical problem to be solved in the utility model to provide a kind of easy for installation, simple to operate, safe and reliable electromagnetic interlock device.
In order to solve above technical problem, the utility model provides a kind of electromagnetic interlock device, the operating grip of on-load switch is other is provided with electromagnetic lock, electromagnetic lock is connected with on-load switch, on-load switch closes a floodgate, and electromagnetic lock is energized, then the intrinsic blocking lever of electromagnetic lock stretches out, run through the groove of operating grip hollow, lock operation handle zero rotates.
Described electromagnetic lock is provided with emergency release mouth, opens emergency release mouth, screws out blocking lever.
The side of described electromagnetic lock is provided with auxiliary contact, and these auxiliary contact contact with the contact of circuit breaker.
Superior effect of the present utility model is:
1) easy for installation, simple to operate, safe and reliable;
2) not only economize on resources, greatly reduce workload, and highly versatile, in all types of on-load switch that can be used for dissimilar high-tension switch cabinet and isolating switch.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 shows structural representation of the present utility model; Fig. 2 shows end view of the present utility model.As depicted in figs. 1 and 2, the utility model provides a kind of electromagnetic interlock device, the operating grip 1 of on-load switch is other is provided with electromagnetic lock 2, electromagnetic lock 2 is connected with on-load switch, on-load switch closes a floodgate, and electromagnetic lock 2 is energized, then the intrinsic blocking lever of electromagnetic lock stretches out, run through the groove of operating grip 1 hollow, lock operation handle 1 zero rotates.
Described electromagnetic lock 2 is provided with emergency release mouth 7, opens emergency release mouth 7, screws out blocking lever.
The side of described electromagnetic lock 2 is provided with auxiliary contact 6, and these auxiliary contact 6 contact with the contact of circuit breaker.
Operation principle of the present utility model is: after on-load switch closes a floodgate, after the electromagnetic lock 2 be connected with on-load switch is energized, and intrinsic blocking lever puts in operating handle of load switch 1 by the magnetic force that electromagnetic lock 2 facility produces.In the powered normal work period of system, on-load switch cannot deciliter, only after all load transformer system cut-offs, the blocking lever of electromagnetic lock 2 just can indentation body, thus facilitates on-load switch separating brake.In case of emergency, also can open emergency release mouth 7 with the unlock key of customization, carry out emergency release, thus make on-load switch separating brake.
The foregoing is only preferred embodiments of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
