The switch cubicle anti-misoperation locking device is arranged on switch cubicle, it is necessary to operational grounding disconnecting link or opening door of switch cabinet
When, operation key 3000 is inserted into the key solution lockhole of switch cubicle anti-misoperation locking lockset 4000, obtains equipment live information,
When operation key 3000 detects no electricity, the operation button 130 on push key 3000, you can it is anti-error to open switch cubicle
Lock set 4000；Meanwhile operate key 3000 and record electrical verification and unlocking information, by these information transmissions to host computer 1000.
During specific works, switch cubicle anti-misoperation locking lockset is arranged on high-voltage switch cabinet door or grounding switch operating mechanism
It is upper, it is necessary to operational grounding disconnecting link or when opening cabinet door, key 3000 will be operated be inserted into the unblock of switch cubicle anti-misoperation locking lockset
In mechanism, operation key 3000, which authorizes, obtains equipment live information, when detecting equipment live, operates the behaviour on key 3000
Make button 130 to be withstood by the solenoid 140 in operation key, operation key 3000 can not press the operation button 130, so that can not
Release the locking of equipment；, can be with the operation button 130 of push on the key, anti-misoperation locking dress when detecting equipment without electricity
Put the locking released to equipment.
In the square groove 31 of the unlocking mechanism 3 of the switch cubicle anti-misoperation locking lockset can according to scene need install or
Wireless code sheet is not installed.Preferably, installation is wireless in the square groove 31 of the unlocking mechanism 3 of the switch cubicle anti-misoperation locking lockset
Chip.
Preferably, during unblock, the square groove 31 on the insertion anti-misoperation locking device of reading terminal 113 of the operation on the key
In.
Working method：
As shown in Figure 11, Figure 12, it is necessary to operational grounding disconnecting link or open cabinet door when, operation key 3000 insert switch cubicle prevents
By mistake after lock set, the latch release shaft 111 operated on the key is connected with the unblock rotary head 32 on anti-misoperation locking device, and operation is on the key
Electrode axis 112 be connected with the electrode stem 33 on anti-misoperation locking device, operate reading terminal 113 on the key and insert anti-misoperation locking dress
In the square groove 31 put, so as to which operation key 3000 be linked together with switch cubicle anti-misoperation locking lockset.Such as Fig. 5, by
