Further, sensor body also comprises: back up pad, offer through hole on the back up pad, and back up pad is arranged on a side of insulation support body, and second end of signal wire passes through hole.
Further, signal receiving device is an antenna.
Further, it is rectangular-shaped that insulation support body is, and insulation support body has first side away from back up pad, and antenna is near first side.
Further, insulation support body is in the form of annular discs, and insulation support body has first side away from back up pad, and antenna is near first side.
Further, antenna and back up pad parallel.
Further, magnet is arranged in the insulation support body and near first side.
Further, magnet is a plurality of, a plurality of magnet be arranged on equably antenna around.
Further, magnet is embedded in the inside of insulation support body, and perhaps magnet connects or is embedded on the outside surface of insulation support body.
Further, magnet is strong magnet.
In the technical scheme of the utility model, sensor comprises: sensor body and magnet.Wherein, sensor body comprises: insulation support body, and signal receiving device and signal wire, signal receiving device are arranged on the inside of insulation support body; First end of signal wire links to each other with signal receiving device, and second end of signal wire passes insulation support body.Magnet is arranged on the insulation support body.The utility model is through being provided with magnet on sensor body; Sensor body is adsorbed on the switchgear with ferrous material shell; Prevented the error that the artificial origin produces when measuring; When realizing that the inner shelf depreciation of switching devices is effectively accurately measured, guaranteed relevant device and tester's safety again.
