Description
Technical field
The present invention relates to electrical protection apparatus field, in particular to a kind of throwing of electic protection pressing plate move back detection circuit and
Electic protection pressing plate.
Background technique
Electic protection pressing plate is also named protection in flakes, the tripping of electrical protective relaying device is judged for electrical maintenance personnel
Circuit state.It is the modular design of existing protection pressing plate as shown in Figure 1, usually there is connection plug and insulation knob, pass through
Connection plug is plugged in the metal consent of pressing plate pedestal or two insulation of oblique cutting to chassis side is inserted by the rotation of knob
In mouthful, realize that operation is moved back in the throwing of pressing plate, for example, in example disclosed in No. 2013202650382 Chinese invention, but it is such
There is very big security risk or inconvenience in protection pressing plate, behaviour is moved back in the throwing for being particularly due to existing protection pressing plate in use
It is largely dependent upon the manual operation of service personnel, on the one hand due to negligence, may be forgotten after having overhauled extensive
Multiple conducting connection causes electronic equipment not work, and on the other hand, moves back conducting since the damping design of protection pressing plate itself causes to throw
Position is not in place, and turn-on effect can not be protected, at this time if the serious consequence such as burning by will lead to if high current.
In the prior art this is proposed to solve, such as No. 2017208739167 are invented being arranged outside connection sheet for proposition
Light emitting diode, when circuit formation is connected, LED lighting is to characterize current throwing location status, when diode extinguishes,
Indicate that circuit disconnects, current is to move back location status.But this needs to do the internal structure of entire connection sheet change design, Er Qiezeng
Add LED lighting circuit itself to be located on pressing plate, interference is be easy to cause to circuit；In addition, being invented at No. 2017108795602
A kind of identified using two dimensional code to carry out identification and determinations is to put into and exit state, but the program is proposed in patent application
It needs to scan and recognize by the hand mobile terminal (mobile phone) of user, there is inconvenience in practical applications, and increase maintenance
The operation of personnel can also forget scanning recognition, still be unable to monitor if forgetting to restore investment.
