Row, which is powered, to be illuminated.It is intended that the further simulating grid of extinguishing suddenly with illuminator 0233 is occurred by accident impact
Power failure.
Operating unit 0300 is grounded for the maloperation for the safe simulation live connection of ground wire 0330 of operator, with touching
Send out the warning consequence of maloperation.Ground connection operating unit 0300 is including the insulation body of rod 0310 and is set to insulation 0310 one end of the body of rod
Wire 0320, wire 0320 pass through 0330 dead earth of ground line.Wherein, wire 0320 can be iron wire.
When demonstration, operator must wear insulating glove, insulating boot, safety cap etc. and carry out demonstration operation, to guarantee to grasp
Make the personal safety of personnel.0330 surface is grounded by wrapped with insulation, avoids leaking electricity.
Exemplarily, live connection of ground wire body-sensing device 1000 further includes that demonstration area is isolated with what extraneous holding was dielectrically separated from
0400, three-phase conducting wire 0110 is all set in metal end 0120 is isolated demonstration area 0400, guarantee the personal safety of operator with
The property safety of other equipment.Exemplarily, isolation demonstration area 0400 is protected by insulation floor (such as electro-insulating rubber is made) and insulation
Column surrounds.
Before demonstration, closes air switch and give route power transmission, is i.e. metal end 0120 remains powered on state, at this time indicator light
0212 bright expression route electrification.Alternating-current normally-open intermediate relay 0221 is powered, and normally-closed contact disconnects, at this time illuminator 0233
Bright, demonstration power grid operates normally.
Operator be grounded the wire 0320 of operating unit 0300 and a certain metal end 0120 (such as with A phase 0111
Corresponding metal end 0120) it contacts, wire 0320 will generate electric spark, enhance visual effect.
Meanwhile the electric current of the metal end 0120 increased dramatically, and disconnect corresponding air switch tripping.Since network loses
Pressure, o-volt protection relay 0211 start and make that the conducting of sound/light alarm circuit 0220, to exchange normally closed intermediate relay 0232 disconnected
It opens.Correspondingly, sound/light alarm circuit 0220 issues sound-light alarm, and exchanging the normally closed disconnection of intermediate relay 0232 makes illuminator
0233 extinguishes, simulating grid tripping effect.
In all examples being illustrated and described herein, any occurrence should be construed as merely illustratively, without
It is as limitation, therefore, other examples of exemplary embodiment can have different values.
It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, does not then need that it is further defined and explained in subsequent attached drawing.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to the scope of the utility model.It should be pointed out that for the ordinary skill of this field
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection scope of utility model.Therefore, the protection scope of the utility model should be determined by the appended claims.
