Make so that the connecting rod driving switch is closed or disconnects, to generate a signal, i.e. power supply signal.The production of the power supply signal
It is raw to indicate that the conductive moving component 13 is detached with the conducting connecting part 110 and/or the conducting connecting part 120.For
Ensure that the reliability of detection, first detection part could be provided as two or more and (be provided in Fig. 2 and Fig. 3
Two limit switches 16), the only described first processor has received the power supply signal of these first detection parts generation,
First power supply is controlled according to the power supply signal to be powered to the target device by the leading-in end 11.
In practical applications, first detection part can also be microswitch or sensor etc..The microswitch,
Also known as sensitive switch, operation principle is similar to the limit switch of the contact, outer mechanical force by actuated element (push-piece,
Button, lever, idler wheel etc.) power is acted on action reed, snap action is generated when acting reed and being displaced to critical point, is made
Act movable contact and fixed contact quick-make or the disconnection of reed end.The sensor can be displacement sensor, laser
Sensor etc., institute's displacement sensors are used to detect the distance that the conductive moving component 13 moves, if mobile distance reaches pre-
If distance, then signal is generated, indicates that the conductive moving component 13 is connected with the conducting connecting part 110 and/or the conduction
Fitting 120 detaches；The laser sensor can be arranged in predeterminated position, be used cooperatively with laser emitter, when the conduction
When moving component 13 moves to predeterminated position, the laser that the laser emitter is sent to the laser sensor is sheltered from, this
When laser sensor can generate signal, indicate that the conductive moving component 13 is and the conducting connecting part 110 and/or institute
State the separation of conducting connecting part 120.
In practical applications, when enter powering mode after, need for target device it is lasting high-voltage electricity is provided so that equipment
It can work normally.But if continue when the high-voltage electricity, when and disconnect, target device may can not work normally, sternly
It is possible that fire or other is caused to cause the situation of security threat to people and equipment in the case of weight, it is therefore desirable in power supply mould
Further ensure that the power supply of high-voltage electricity is safe and reliable under formula.In order to realize that the target, the power supply unit can also include
Second detection part and second processor (being not shown in Fig. 2 and Fig. 3).Second detection part is used in the powering mode
Under, detect whether the driving mechanism 14 drives the conductive moving component 13 in the conducting connecting part for leaving the leading-in end 11
110 and/or the exit 12 conducting connecting part 120 after be maintained at predeterminated position, if so, being considered at safe power supply
In；If not, then it is assumed that power supply is dangerous, needs to send power-off signal to the second processor at this time.The second processor,
The discharge mode is entered by the powering mode for controlling the driving mechanism 14 according to the power-off signal, that is, described
Driving mechanism 14 drive the conductive moving component 13 respectively with the conducting connecting part 110 and the conducting connecting part 120 into
Row contact, to discharge high-voltage electricity, avoids it to be constituted discharge loop with the leading-in end 11 and the exit 12
Security threat is caused to equipment and human body.

It touches, and triggers the microswitch 17 and generate signal.Signal is generated in addition to triggering the microswitch 17, the compressing is with refitting
Setting 19 also can have another effect, that is, be insufficient to allow the armature 141 in the suction that the electromagnet 140 generates
It drives the conductive moving component 13 to be moved to predeterminated position, or is not enough to that the armature 141 is driven to trigger first detection
When component, it can be helped using the compressing gravity of itself of counter weight device 19.
In practical applications, second detection part can also be that limit switch, sensor etc., the present invention are not done specifically
It limits.The testing principle of second detection part is similar to first detection part, and details are not described herein again.In addition, in order to
The reliability for further increasing second detection part detection, can be arranged at least two second detection parts (such as
There are two microswitches 17 for setting in Fig. 2 and Fig. 3), only when the second processor all receives described at least two second
The power-off signal of detection part just controls the driving mechanism 14 described in powering mode entrance according to the power-off signal
Discharge mode.
Referring to Fig. 3, under the discharge mode, the electromagnet 140 is no longer generated because of power-off to the armature 141
Suction, the elastic force apparatus during reinstatement by the armature 141 and the conductive moving component 13 upwards
It boosts, it is described to draw until the conductive moving component 13 is contacted with the conducting connecting part 110 and the conducting connecting part 120
Enter end 11 and discharge loop is formed by the conductive moving component 13 and the exit 12, high-voltage electricity is imported into the earth.In order to
The high-voltage electricity is quickly imported into the earth, the power supply unit can also include release resistance 20.The release resistance 20
Resistance value can be depending on the length of voltage release time, and if desired release finishes within a short period of time, then the release resistance
20 resistance value is smaller；If desired it discharges for a long time, then the resistance value of the release resistance 20 is larger.
In addition, while the armature 141 is bounced, also drives the compressing counter weight device 19 to leave the fine motion and open
Close 17.
In practical applications, the power supply unit can also include power relay, and the power relay includes first
Contact, first contact portion is between first detection part and the first processor.
First detection part is specifically used for detecting whether the conductive moving component connects with the conductive of the leading-in end
The conducting connecting part of fitting and/or the exit detaches, if so, sending power supply signal to first contact.If described
First contact is normally opened contact, then first contact, for being closed according to the power supply signal, so that the first processor
First power supply is controlled according to closure signal to be powered to the target device by the leading-in end；If described first touches
Point is normally-closed contact, then first contact, for being disconnected according to the power supply signal, so that the first processor is according to disconnected
ON signal controls first power supply and is powered to the target device by the leading-in end.
