When being measured using the utility model insulation resistance measuring device to insulaion resistance, due to insulation measurement just Probe and negative probe are all fixed settings, therefore just will pop one's head in and bear probe without supernumerary and keep fixing;And just pop one's head in, Connecting wire between negative probe and Insulation Resistance Tester is wound up with automatic winder, is carrying out insulation measurement When, positive probe and the negative great free degree of probe are given, that is to say can put Insulation Resistance Tester one horizontal position Put, by by connecting wire from automatic winder it is stretched come, you can with realize measure insulaion resistance over long distances, reduce Measurement error.
As a kind of improvement of the present utility model, the positive wire and cathode conductor are located in a spaghetti, described Spaghetti is wrapped on automatic winder.
As it is of the present utility model it is a kind of improve, the front end of the positive probe and negative probe opposite to each other to the outside lateral bend in ground, Form the ring contact with opening.
As it is of the present utility model it is a kind of improve, before the positive probe and negative probe are fixed on mounting seat in an inclined manner End, front wide and rear narrow Y type fork shape is formed between positive probe and negative probe.
Compared with prior art, the utility model has advantages below:
Positive probe of the present utility model and negative probe are all fixed settings, therefore just will pop one's head in and bear spy without supernumerary Head keeps fixing, and improves measurement efficiency;And just pop one's head in, bear to pop one's head in and used certainly the connecting wire between Insulation Resistance Tester Dynamic winder is wound up, and when carrying out insulation measurement, gives positive probe and the negative great free degree of probe, that is to say can So that Insulation Resistance Tester is put on a horizontal position, by by connecting wire from automatic winder it is stretched come, It can realize and measure insulaion resistance over long distances, reduce measurement error.
