Detailed Description

Referring to the drawings, (taking three sensing media A, B, C as examples) a non-contact sensing type high-voltage electrified display device, the structure of the non-contact sensing type high-voltage electrified display device comprises a sensor and a display; wherein the sensor is connected to the display by a shielded connection.

The display consists of a power indicator lamp 1, L2 and L3, a self-checking button 3, a locking signal lamp 4, a nuclear phase interface 5, a standard USB butt joint interface 6, a shielding line A item interface 7, a shielding line B item interface 8, a shielding line C item interface 9 and a grounding wire 10; the power indicator lamp 1 is arranged at the left upper corner of the main panel of the display, the L1, L2 and L3 display lamps 2 are arranged on the right side of the power indicator lamp 1 in parallel, the self-checking button 3 is arranged at the right upper corner of the main panel of the display, the locking signal lamp 4 is arranged below the self-checking button 3, the nuclear phase interface 5 is arranged below the L1, L2 and L3 display lamps 2, the standard USB docking interface 6 is arranged at the left lower corner of the main panel of the display, and the shielding wire A item interface 7, the shielding wire B item interface 8, the shielding wire C item interface 9 and the grounding wire 10 are arranged at the rear side of the display.

The sensor consists of a shielding wire 11, a plastic insulation box 12, a wire passing terminal 13, a wire fixing screw 14, a wire pressing push plate 15, a reset spring 16 and a stop screw 17; one end of the shielding wire 11 is connected to the plastic insulation box 12 through a fixing wire on the wire passing terminal 13 by using a screw 14, the other end of the shielding wire 11 bypasses the induction medium, penetrates through a shielding wire hole reserved in the plastic insulation box 12 and is fixed to the plastic insulation box 12 through a wire pressing push plate 15, a stop screw 17 is connected with the wire pressing push plate 15, and a reset spring 16 is located above the stop screw 17 and is connected with the wire pressing push plate 15.

In actual operation, the three sensors are respectively in butt joint with three items 18 of the induction medium A, B, C through the shielding wires 11, and when the sensors receive high-voltage charged body electric field signals, the signals are transmitted to a display for comparison and judgment; when the three items of the detected induction medium A, B, C18 are electrified, the electrified display 2 is L1, L2 and L3, the display lamp is on, the forced locking signal lamp 4 is on, and the power supply display lamp 1 is on; when the three items of the sensing medium A, B, C to be tested 18 are not electrified, the electrified display 2 is that the L1, L2 and L3 display lamps are turned off, the forced locking signal lamp 4 is also turned off, and the power supply display lamp 1 is turned off.
