Abstract
A short circuiting line with a fuse comprises two short-circuit pens and an insulated conductor (5) connected with the two short-circuit pens; insulators (2) are coated at one ends of metal probes (1) to form the short-circuit pens; the sides of the insulators connected with the metal probes adopt hollow bodies; and a fuse (3) is arranged in the cavity of one of the hollow bodies. According to the short circuiting line provided by the utility model, during secondary inspection and repair, and debugging of the transformer station and other operations, the debugging personnel and equipment are ensured to be safe due to the AC short circuit and DC short circuit; and besides, the fuse can be disassembled and replaced, and the purpose of reusability is achieved.
Description
Technical field
It is the used short circuit tool construction technical field of short circuit voltage that the utility model relates in substation secondary maintenance and the debugging.
Background technology
At present in work such as substation secondary maintenance, debugging, realize contact conducting, relay adhesive for short circuit voltage or break off, when reaching purpose such as remote signalling is checked, function on, often use single-core line as shorting stub.If the commissioning staff causes the AC and DC short circuit accidentally when short circuit, moment just can produce very big short circuit current, thereby produces huge heat.This moment, heat had little time to pass, will scaling loss equipment, and cause power source trip, even possibly cause the power supply overstep tripping, and influence the normal operation of substation equipment, the commissioning staff also possibly burn in the time of seriously.In recent years, the commissioning staff's that burns accident happens occasionally because short circuit voltage causes the AC and DC short circuit.
Summary of the invention
The purpose of the utility model is in order to solve the problem that prior art exists, to provide a kind of when the AC and DC short circuit takes place, can breaking off the shorting stub of the band fusing insurance of shorting stub, protection commissioning staff and device security rapidly.
The purpose of the utility model realizes through following scheme.
A kind of shorting stub with the fusing insurance; Comprise two by insulator coated metal pop one's head in an end short circuit pen that forms and the insulated conductor that is connected two short circuit pens; The inner side of joining with metal probe of insulator is a ducted body, in the cavity of ducted body, is provided with the fusing fuse.
A short circuit pen of the utility model is fixedlyed connected with insulated conductor, and another short circuit pen is connected by threaded connector with insulated conductor.
The said fusing fuse of the utility model is a tube fuse.
When using the shorting stub generation AC and DC short circuit of this band fusing insurance; Short circuit current is behind the load current value that reaches the fusing fuse, and fuse fuses immediately, and shorting stub is broken off; The AC and DC short circuit phenomenon disappears, thereby protects the safety of commissioning staff and equipment to the full extent.
The utility model has not only guaranteed in work such as substation secondary maintenance, debugging; Do not form the infringement that the AC and DC short circuit phenomenon causes commissioning staff and equipment because of short circuit; And owing to a short circuit pen is connected through threaded connector with insulated conductor; The detachable fuse of changing can be reused.
The utility model structural principle is simple, practical, and cost is cheap, is convenient to extensive use.
Further set forth the utility model content below in conjunction with Figure of description.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in the figure, the utility model comprises two by the insulator 2 coated metals short circuit pen and the insulated conductor that is connected two short circuit pens 5 that 1 one ends form of popping one's head in, and has constituted a shorting stub.The handgrip part of short circuit pen during as short circuit.The inner side of joining with metal probe of insulator is a ducted body, in the cavity of ducted body, is provided with fusing fuse 3.The fusing fuse can be selected all kinds of fuses of prior art, and present embodiment is selected tube fuse.A short circuit pen of the utility model is fixedly connected with insulated conductor, and the insulator of another short circuit pen is connected through threaded connector 4 with insulated conductor.Through the threaded connector of outwarding winding is the detachable insulator of opening the short circuit pen, so that place and change tube fuse.
Claims (3)
1. shorting stub with the fusing insurance; It is characterized in that; Comprise two by insulator (2) coated metal probe (1) one end short circuit pen that forms and the insulated conductor that is connected two short circuit pens (5); The inner side of joining with metal probe of insulator is a ducted body, in the cavity of ducted body, is provided with fusing fuse (3).
2. a kind of shorting stub with the fusing insurance according to claim 1 is characterized in that a short circuit pen is fixedly connected with insulated conductor, and another short circuit pen is connected through threaded connector (4) with insulated conductor.
