Abstract
The utility model discloses an emergency tripping gear used for a switch cabinet. The emergency tripping gear comprises a starter gear disposed on a cabinet door, and a push rod used to start a trip push button of a breaker. The starter gear comprises a rotation handle disposed outside the cabinet door and a linkage rod which is rotatably connected with the cabinet door through a lead screw. The linkage rod extends into a support frame which is disposed on an inner side of the cabinet door and used to support the push rod. The linkage rod is disposed opposite to the push rod. The device is simple in structure and convenient in operation. When electric tripping cannot normally operate caused by secondary failure and manual tripping is needed, the manual tripping can be completed without opening the cabinet door, thereby ensuring safety of an operator, and ensuring safety of the circuit and device.
Description
Technical field
The utility model relates to switch cubicle field, is specifically related to a kind of emergency tripping device for switch cubicle.
Background technology
Along with the fast development of China's economy, as basic power industry, also obtained for a long time development fast, as one of visual plant in power construction, the market demand of switch cubicle is very large, also high voltage switchgear is had higher requirement simultaneously.The middle-placed switch cabinet of extensive use in the market; can meet various instructions for use; wherein; requisite circuit breaker is for distributing electric energy; power circuit and motor etc. are carried out to protection; can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And after disjunction fault current, generally do not need to change parts.At present, obtain a wide range of applications.But when there is electric leakage situation, circuit breaker is normal operation not, does not disconnect, and may be the reason of circuit breaker own, and residual action current has uprised, and has exceeded specified scope, now just need to, by emergency trip button, allow circuit breaker disconnect.Emergency tripping device of the prior art, complex structure, inconvenient operation.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, provides a kind of simple in structure, easy to operate, can in the situation that not opening cabinet door, complete the action of threading off, and guarantees personal security.
For achieving the above object, the technical solution of the utility model is to provide a kind of emergency tripping device for switch cubicle, comprise the starting drive that is arranged on cabinet door and for starting the push rod of the trip push button of circuit breaker, described starting drive comprises and is arranged on described the cabinet swing handle of portion and the trace being rotationally connected by leading screw and described cabinet door outdoors, described trace extend to be arranged on described cabinet door inner side for supporting in the bracing frame of push rod, the setting corresponding to described push rod of described trace.
Preferably technical scheme is, described connecting rod and described push rod can be structure as a whole, and can be also Split type structures, and integrative-structure transmission is good, easily manufactured; Split type structure flexibility is high, convenient disassembly.
Convenient in order to use, transmission is better, and preferred technical scheme is in support frame as described above, to be provided with back-moving spring.
For conserve space, make structure compacter, and convenient installation, preferred technical scheme is that support frame as described above is modular construction, by supporting bracket, is bolted to connection on described cabinet door inwall.
More accurate in order to locate, preferred technical scheme is in cabinet, to be provided with the gathering sill for localization handspike.
For easy for installation, preferred technical scheme is that described gathering sill is fixedly installed on cabinet base plate.
Advantage of the present utility model and beneficial effect are: the utility model is simple in structure, easy to operate, when secondary failure cannot electronic dropout cannot work while needing hand tripping, do not need to open cabinet door and just can complete, ensure operator safety, and guaranteed the safety of circuit and equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection range of the present utility model with this.
As shown in Figure 1, a kind of emergency tripping device for switch cubicle, comprise the starting drive that is arranged on cabinet door 1 and for starting the push rod 6 of the trip push button 3 of circuit breaker 2, described starting drive comprises and is arranged on described the cabinet swing handle 4 of portion and the trace 5 being rotationally connected by leading screw and described cabinet door 1 outdoors, described trace 5 extend to be arranged on described cabinet door inner side for supporting in the bracing frame 7 of push rod 6, described trace 5 and the corresponding setting of described push rod 6.

On the basis of embodiment 1, the utility model preferably technical scheme also comprises, is provided with back-moving spring 8 in support frame as described above 7, and this spring one end is spacing by the sidewall of bracing frame, and one end arranges a limiting plate 9, and limiting plate 9 is dismountable is fixed on push rod for this.
Embodiment 4
On the basis of embodiment 3, the utility model preferably technical scheme also comprises, support frame as described above 7 is modular construction, by supporting bracket, is bolted to connection on described cabinet door 1 inwall.
On the basis of embodiment 4, the utility model preferably technical scheme also comprises, is provided with the gathering sill 10 for localization handspike 6 in cabinet.
On the basis of embodiment 5, the utility model preferably technical scheme also comprises, described gathering sill 10 is fixedly installed on cabinet base plate.
Handle is arranged on cabinet outdoors, and during emergency trip, swing handle, drives door inner push-rod to move horizontally the trip push button pushing up on breaker body, and hand tripping button completes emergency trip, and push rod is by spring automatic retraction.When secondary failure cannot electronic dropout cannot work while needing hand tripping, do not need to open cabinet door and just can complete, ensured operator safety.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
