Having affected, this can cause institute's Monitoring Data inaccurate, makes current difference not reflect in time, and is monitored circuit relatively
Few, cause needing multiple monitoring device to current monitoring, not only monitor complex circuit, also expend substantial amounts of expense, therefore, pin
The problems referred to above are proposed a kind of current difference monitoring device.
Utility model content
Having problems for above-mentioned prior art, this utility model provides a kind of current difference monitoring device, uses electric current mutual
Sensor faradic current is abnormal, and is connected with sliding support by current transformer, can be adjusted its position, controllability
The best, this device can arrange multiple current transformer device, solves problem present in background.
For achieving the above object, the technical solution adopted in the utility model is: a kind of current difference monitoring device, including housing with
And it is arranged on the current transformer of described housing tip；Described surface of shell arranges rectangular patch hole, and described rectangular patch hole one
End arranges signal projector；Inside described rectangular patch hole, binding post is set；Described current transformer bottom arranges sliding support,
And described sliding support surface configuration regulation bolt；Described housing side arranges guide-track groove, and described shell one end arranges wiring hole；
Described surface of shell arranges switch, and described switch one end arranges wave filter；Described wave filter one end arranges electronic displays.
Further, described binding post and described electronic displays are two, and described binding post with in described electronic displays
Portion is electrically connected with.
Further, inside described sliding support with guide-track groove outside distance be 2-3mm.
Further, described regulation bolt is two, and described regulation bolt diameter of section is less than guide-track groove width 1-2mm.
Further, described current transformer is hollow cylindrical structure, and described current transformer width is more than described case width,
And described current transformer inside diameter is 30-40mm.
Further, described electronic displays is internal with described signal projector is electrically connected with.
The beneficial effects of the utility model are: this kind of current difference monitoring device uses current transformer faradic current extremely,
And being connected with sliding support by current transformer, can be adjusted its position, controllability is the best, and this device is permissible
Multiple current transformer device is set, adds the adjustability of device.
