The old high voltage shore power power supply that can run is also to have very big potential safety hazard.
Utility model content
The purpose of this utility model be to propose it is a kind of it is safe and reliable, high voltage shore power power supply normal operation can be ensured
A kind of high voltage shore power power safety protector.
The technical solution of the utility model is：A kind of high voltage shore power power safety protector, including master control borad and outer
Peripheral equipment, there is single-chip microcomputer on master control borad, ancillary equipment includes high pressure sampling plate, direct current sampling plate, cabinet door travel switch and electromagnetism
Cabinet door lock, the master control borad respectively with high voltage shore power power supply, high pressure sampling plate, direct current sampling plate, cabinet door travel switch and electromagnetism
Cabinet door lock is connected, and the high pressure sampling plate, direct current sampling plate, control panel are connected with high voltage shore power power supply.
Further, the high pressure sampling plate is that the magnitude of voltage collected is converted into 0~5V voltages letter using high-tension resistive
Number and be transmitted to master control borad.
Further, the DC voltage value collected is converted into 0~5V voltage signals by the direct current sampling plate using resistance
And it is transmitted to master control borad.
Further, the travel switch is fixed in cabinet door, and travel switch will be touched now by shutting cabinet door rack metal plate
Travel switch acts, and travel switch is normally open, and travel switch is normally closed after shutting up the door carefully, and the action of travel switch can pass through
24V voltages send master control borad to.
Further, there are mechanical lock part and electromagnetic lock part, electromagnetic lock part locking cabinet door inside the electromagnetism cabinet door lock
It will be unable to open using mechanical lock, only electromagnetic lock, which receives the unlocking signal that master control borad is sent, could open cabinet door.
The utility model has following technique effect：If the utility model is real-time to cabinet door to monitor equipment cabinet before activation
Door, which does not shut master control borad and will send cabinet door, is not turned off signal to high voltage power supply, now high voltage shore power power supply be can not be to input
Combined floodgate power transmission.
The utility model is that can not open cabinet door in high voltage shore power power supply running, if opening cabinet door control by force
Plate will send alarm command high voltage shore power power supply by autostop and send alarm.
The utility model each power cell internal DC voltage of real-time sampling under high voltage shore power power supply stopped status, such as
The too high control panel of fruit internal dc voltage will continue to send locking cabinet door signal, be also now that can not open cabinet door to prevent to pacify
Full accident, if alarm command will also be sent by opening cabinet door control panel by force.

Fig. 2 is utility model works flow chart.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
As shown in Figure 1-2, a kind of high voltage shore power power safety protector, including master control borad and ancillary equipment, master control
There is single-chip microcomputer on plate, ancillary equipment includes high pressure sampling plate, direct current sampling plate, cabinet door travel switch and electromagnetism cabinet door lock, described
Master control borad is connected with high voltage shore power power supply, high pressure sampling plate, direct current sampling plate, cabinet door travel switch with electromagnetism cabinet door lock respectively
Connect, high pressure sampling plate, direct current sampling plate, control panel are connected with high voltage shore power power supply, main for collection voltages value and current value
Whether control plate is shut by the open and-shut mode detection device cabinet door of travel switch, and judges whether high voltage shore power power supply needs to disconnect
Input circuit breaker trip high input voltage is simultaneously emitted by alarm.
There is single-chip microcomputer on master control borad described in the utility model, primary control program programming is entered in single-chip microcomputer, primary control program will divide
High pressure sampling plate, direct current sampling plate, cabinet door travel switch and electromagnetism cabinet door lock are analysed to parameter out.
High pressure sampling plate described in the utility model is that the magnitude of voltage collected is converted into 0~5V voltages using high-tension resistive
Signal is simultaneously transmitted to master control borad.
The DC voltage value collected is converted into 0~5V electricity by direct current sampling plate described in the utility model also with resistance
Pressure signal is simultaneously transmitted to master control borad.
Travel switch described in the utility model is fixed in cabinet door, shut cabinet door rack metal plate will touch travel switch this
When travel switch act, travel switch is normally open, shutting up the door carefully after travel switch be it is normally closed, the action of travel switch can lead to
Cross 24V voltages and send master control borad to.
There are mechanical lock part and electromagnetic lock part, electromagnetic lock part locking cabinet inside electromagnetism cabinet door lock described in the utility model
Goalkeeper can not utilize mechanical lock to open, and only electromagnetic lock, which receives the unlocking signal that master control borad is sent, could open cabinet door.
Utility model works flow is whether master control borad is shut by the open and-shut mode detection device cabinet door of travel switch,
Master control borad, which sends cabinet door and shut, under cabinet door closed state allows switching signal to give high voltage shore power power supply, and now high voltage shore power power supply can
Operate input to close a floodgate, master control borad transmission cabinet door does not shut signal and gives high voltage shore power power supply under the non-closed state of cabinet door, now high
Pressure shore electric power sends alarm and can not closed a floodgate.
The signal that master control plate analysis high pressure sampling plate provides determines whether high voltage shore power power input has high pressure, magnitude of voltage
It is how many and exports to master control borad, input has master control borad under high pressure conditions to send semaphore lock cabinet door and send electrification in high voltage
Signal gives high voltage shore power power supply.
Master control borad is not turned off signal, high voltage shore power by cabinet door is sent when cabinet door is opened in high voltage shore power power supply running status
Power supply, which receives signal automatic emergency stop and disconnects input circuit breaker trip high input voltage, is simultaneously emitted by alarm.
The high voltage shore power power supply signal that master control borad provides real-time monitoring direct current sampling plate under stopped status determines to be
Whether system is internal has residual voltage, if residual voltage master control borad continues to send semaphore lock cabinet door, when master control borad detects
Unlocking signal is exported during internal system noresidue voltage and states of cabinet door is issued high voltage shore power power supply master control.
