Abstract
The utility model discloses a simulation fuse which comprising a middle connecting rod. A button through hole is arranged on one side of the middle connecting rod. A button rod is arranged in the button through hole. Mounting sleeves are respectively arranged on both ends of the middle connecting rod. An impactor is arranged in the mounting sleeve close to the button rod. The impactor is connected with one end of the middle connecting rod. A first spring is arranged in the middle connecting rod. The first spring is connected with the impactor. According to the utility model, the provided simulation fuse has the advantages of simple structure and convenient operation; the operation reliability of a switch cabinet is improved; the workload of operation staff and maintenance staff can be reduced; the fault incidence rate of the switch cabinet is greatly reduced; and the reliability of equipment power supply and the electricity utilization of a user can be ensured.
Description
Technical field
The utility model relates to a kind of simulation fuse.
Background technology
XGN68-12 type switch cubicle is widely used in power grid construction.And the feeder clearance of XGN68-12 type switch cubicle (vacuum load switch-pull-out type fuse rotation isolation plug-in strip combined electrical apparatus cabinet) does not generally configure microcomputer or relay protection, and adopt XRNT-12 type high-voltage and current-limitation fuse as overcurrent protection high voltage fuse.During high-voltage wire iron-melting fusing, top striker (striker) ejects, by breaker open operation.When checking experiment is carried out to XGN68-12 type switch cubicle in scene, in cabinet, equipment component can be tested one by one, but even jumping device generally can only carry out the work such as visual examination, cleaning, rotating property inspection, therefore for potential safety hazard is buried in the normal use of XGN68-12 type switch cubicle.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of simulation fuse, it is simple in structure, easy to operate, not only improve switch cubicle reliability of operation, reduced operations staff and maintainer's workload, and greatly reduce switch cubicle rate of breakdown, the reliability of support equipment power supply and user power utilization.
The utility model is the object that reaches above-mentioned, and the utility model adopts following technical scheme:
A simulation fuse, comprises middle brace rod, and a side of described middle brace rod offers button pass through hole, in described button pass through hole, button spindle is installed; Described middle brace rod two ends are separately installed with installation sleeve, in the described close installation sleeve of button spindle one side, striker is installed, and described striker are connected with one end of middle brace rod; The first spring is installed in described middle brace rod, and described the first spring is connected with striker.
Described button spindle is socketed with the second spring outward.
Described middle brace rod is threaded with installation sleeve.
The beneficial effects of the utility model are: the utility model provides a kind of simulation fuse, it is simple in structure, easy to operate, not only improve switch cubicle reliability of operation, reduced operations staff and maintainer's workload, and greatly reduce switch cubicle rate of breakdown, the reliability of support equipment power supply and user power utilization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the present embodiment provides a kind of simulation fuse, comprises middle brace rod 1, and a side of described middle brace rod 1 offers button pass through hole, and button spindle 2 is installed in described button pass through hole; Described middle brace rod 1 two ends are separately installed with installation sleeve 3, in the described close installation sleeve 3 of button spindle 2 one sides, striker 4 is installed, and described striker 4 are connected with one end of middle brace rod 1; The first spring 5 is installed in described middle brace rod 1, and described the first spring 5 is connected with striker 4.Outer second spring 6 that is socketed with of described button spindle 2.Described middle brace rod 1 is threaded with installation sleeve 3.
A kind of simulation fuse described in the present embodiment, it is simple in structure, easy to operate, has not only improved switch cubicle reliability of operation, has reduced operations staff and maintainer's workload, and greatly reduce switch cubicle rate of breakdown, the reliability of support equipment power supply and user power utilization.
