The purpose of this utility model can be reached by following measure: a kind of Portable low-pressure nuclear phase insulating bar, it is characterized in that it includes front insulating bar, rear insulating bar and lengthened insulative bar, these three insulating bars are column type, length is all higher than 35cm, front insulating bar is flexibly connected with copper contact by the testing terminal of insertable, two ends are inserted in testing terminal with the Insulation Test line head end of needle-type plug, and the anglec of rotation between copper contact and front insulating bar has-90 degree adjusting range to+90 degree;The rear end of front insulating bar and the front end of rear insulating bar are respectively equipped with symmetrical front link slot and rear link slot, it is flexibly connected with the one end being connected fastening block by bolt at the front link slot of front insulating bar rear end, being flexibly connected with the other end being connected fastening block by bolt at the rear link slot of rear insulating bar front end, front insulating bar all has-180 degree adjusting range to+180 degree with the anglec of rotation being connected between fastening block, connect between fastening block and rear insulating bar;The rear end of rear insulating bar is provided with threaded groove, and the front end of lengthened insulative bar is provided with and threadeds the threaded card convex that groove matches, and rear insulating bar is threaded connection groove, threaded card convex is threadeded with lengthened insulative bar.
This utility model can produce following good effect compared with the prior art: in this utility model can effectively solve power distribution station, low pressure carries out the work inconvenience of cabinet bus bar nuclear phase, the problem that potential safety hazard is big, it is to avoid easily cause the generation of the situations such as electric shock, phase fault in part model low voltage incoming line cabinet.It has:
1, simple in construction, easy to operate.Two sections of rear insulating bar and lengthened insulative bar is connected, front insulating bar and rear insulating bar angle adjustment are also fixed, copper contact and front insulating bar angle adjustment are also fixed, two ends are inserted in testing terminal with the Insulation Test line head end of needle-type plug, and two ends can use in the Insulation Test line end insertion pen meter of universal meter jack with needle-type plug.
2, convenient disassembly, it is simple to carry.Rear insulating bar and lengthened insulative bar convenient disassembly, dismounting is the most collapsible.There is occupation of land little, the feature that quality is little.
3, applied widely.The requirement of nuclear phase work all can be met for different vendor's different model low-voltage cabinet.
4, safety work is ensured.By angle between the front insulating bar of Reasonable adjustment and rear insulating bar during use, it is ensured that human body and electro-mechanical part column pitch are more than 35cm (operating personnel's range of activity and electrical body safe distance during 10kV), and safe distance is ensured.
5, working performance is improved.Ensure safe distance during nuclear phase operation, can avoid using the auxiliary security Work tool such as insulating boot, insulating glove etc..
