Status information is transferred in programmable logic controller (PLC) main website 21, and state letter is shown to control panel status indicator lamp by controller again
23 and monitoring display device 20 man-machine interface in.Operation button 22 is by cable connection to programmable logic controller (PLC) main website simultaneously
In 21, division operation can be carried out to front end earthing isolator by the man-machine interface of operation button 22 and monitoring display device 20,
Treatment, analysis by controller to information, the division for meeting various conditions is instructed and reversely exported, by wireless parties
Formula sends control command to visualization earthed switch cabinet 1.
Normal ground switch remote operation process is as follows：Meet when septum primum leaves pass barring condition, it is high in open position
Less than the operable powered value of regulation, i.e. block signal 13, electrification in high voltage signal 14 has the pressure zone electricity powered value of display electroscope inspection
Signal input to programmable logic controller (PLC) substation 11, substation data are transferred data to by the network switch and wireless bridge
In programmable logic controller (PLC) main website 21, when condition meets, the control instruction to cabinet electromagnetic lock 16 is exported, electromagnetic lock is now solved
Lock, it is ensured that now without high-tension electricity, can open cabinet door carries out the operation of division on the spot to earthed switch to earthed switch cabinet；Work as electromagnetism
After lock unblock, cabinet door is opened simultaneously, and control instruction of the output to cabinet intraoral illumination lamp 15 so that illumination lamp ignition facilitates division to grasp
As when have enough brightness.When there is block signal 13, after electrification in high voltage signal 14, just combined floodgate behaviour can be carried out to earthed switch
Make, i.e., so-called hanging earthing conductor, now there are three kinds of modes that closing operation is carried out to earthing isolator 18, first is by ground connection
The local switch knob operation of the operator input signal 12 in switch cubicle 1；Second is shown by the monitoring in background monitoring center 8
Showing the man machine operation interface of device 20 carries out remote switching operation；3rd is by the mid-game control operation button 22 of background monitoring center 8
Carry out remote switching operation；The instruction of these three closing operations is required to by being passed in programmable logic controller (PLC) main website 21,
When the condition that satisfaction operation is received in main website is, can be by programmable logic controller (PLC) to the instruction of these three control inputs
Stand 11 switching value output module for its cable connection the output control of operation motor 17 instruction, motor is by mechanically connecting bar
It is connected in earthing isolator 18, the division action of earthed switch is reached by controlled motor rotating.For be grounded every
The division state for leaving pass 18 has three kinds of dispaly states, and first is the monitor in real time earthing isolator 18 of infrared hemispherical camera 9
Division status image；Division image is stored by network hard disk video recorder 10, and by wireless transmission method to video figure
As being uploaded, the division image of earthing isolator 18 is shown in the man-machine interface in background monitoring display 20 in real time；
Second is to programmable logic controller (PLC) substation 11, by wireless transmission method by the spacing information Store of the division of earthed switch 18
To be read in the incoming programmable logic controller (PLC) main website 21 of status information, in the man-machine interface in background monitoring display 20 and divided
Conjunction state information；3rd it is same the spacing information of division reached into programmable logic controller (PLC) main website 21 first, and by cable
Connecting valve amount output module and disk control status indicator lamp 23, read division status information, while also may be used by status indicator lamp
Block signal 13 and electrification in high voltage signal 14 are read with by status indicator lamp 23.So connect and can compile by wireless transmission method
Journey logic controller substation 11 and main website 21, complete the reception of signal and issuing for control command so that the remote behaviour of earthed switch
