105 lateral surface of electrical verification luffer boards is provided with handle 107, and handle 107 is corresponding with the position of hanging buckle 111, in electrical verification luffer boards 105 in the open state, and handle 107 is snapped connection with hanging buckle 111, and electrical verification luffer boards 105 can pass through postive stop baffle after opening Hanging buckle 111 on 110 tangles handle 107, keeps the opening state of electrical verification luffer boards 105.

Five anti-lock 109, for being extracted from jack 106 by limiting bolt 108, electrical verification luffer boards 105 and cabinet door 102 are locked It is fixed, electrical verification luffer boards 105, which are opened, after five anti-lock 109 lockings needs first to input password unlock five anti-lock 109.Five anti-lock 109 unlocks need Meet five anti-conditions, and receives the control command that control chip 116 issues.Five anti-lock 109 can be used but be not limited to one kind High-tension switch gear lock.Five anti-lock 109 forced service personnel carry out just electrical equipment according to set safe handling procedures True operation sufficiently meets " five is anti-" and requires to avoid the generation of misoperation fault.

Password Input module 112 is set to 101 outside of cabinet body, and Password Input module 112, control chip 116 and five are anti- Lock 109 is sequentially connected electrically, and encrypted message is sent to control chip for inputting encrypted message by Password Input module 112 116。

Whether the encrypted message and pre-stored encrypted message that control chip 116 is used to judge to receive are consistent, work as reception When the encrypted message arrived is consistent with pre-stored encrypted message, anti-lock 109 unlock of control five, after five anti-lock 109 unlocks, jack Bolt 108 in 106 can be extracted, and after extracting bolt 108, electrical verification luffer boards 105 are openable.

As shown in figure 3, tongue tube 113, circuit board 117 and groove body 118 are equipped on the inside of electrical verification luffer boards 105, in cabinet door 102 Side and 113 corresponding position of tongue tube are equipped with magnet 114.

Key corresponding with mechanical lock 104 is placed with built in groove body 118.

Tongue tube 113 is used to generate state-change according to 114 distance change of magnet, and state-change is sent out Give control chip 116.

Control chip 116 is also used in the encrypted message for not receiving encrypted message or receiving and pre-stored password Information it is inconsistent and receive tongue tube 113 transmission state-change when, to Alarm Unit 115 send trigger signal.

Alarm Unit 115 is electrically connected with control chip 116, after receiving the trigger signal that control chip 116 issues Alarm prompts operation lack of standardization, there is leakage risk.

Alarm Unit 115 includes alarm, digital regulation resistance, power module and switching tube；Switching tube include first electrode, Second electrode and control electrode, second electrode ground connection；Digital regulation resistance includes potentiometer anode, potentiometer cathode, input terminal and defeated Outlet；Potentiometer anode is electrically connected with power module；Potentiometer cathode ground connection；Input terminal is electrically connected with control chip 116；Output End is electrically connected with the control electrode of switching tube；One end of alarm is electrically connected with power module；The other end and switching tube of alarm First electrode electrical connection.

Alarm can be used but be not limited to buzzer siren or combined aural and visual alarm.

Alarm Unit 115 and control chip 116 are integrated in circuit board 117, are set to 105 inside of electrical verification luffer boards.

As shown in figure 4, control chip 116 do not receive encrypted message or the encrypted message received be pre-stored it is close When code information is inconsistent, five anti-lock 109 unlocks will not be controlled, when again control chip 116 receives the state of the transmission of tongue tube 113 Variable signal, control chip 116 control Alarm Unit 115 and alert, prompt operation lack of standardization, there is leakage risk.

The working principle of switchgear 100 provided in this embodiment：When needing to turn on the switch cabinet 100, five anti-lock the last 109 Operations staff processed is correctly operated according to set safe handling procedures, to electrical equipment, to avoid misoperation fault Generation, sufficiently meet after " five anti-" require, Password Input module 112 inputs encrypted message, and encrypted message is sent to control Coremaking piece 116, control chip 116 judge whether the encrypted message that receives and the encrypted message being pre-stored are consistent, when receiving Encrypted message it is consistent with pre-stored encrypted message when, anti-lock 109 unlock of control five, after five anti-lock 109 unlocks, jack 106 In bolt 108 can extract, extract bolt 108 after, electrical verification luffer boards 105 are openable, and operations staff can be examined by electroscopy equipment Whether line inspection trackside charges, such as not charged, then can take out the key in groove body 118, opens mechanical lock 104, closes earthing knife-switch 103, open cabinet door 102；Control chip 116 does not receive encrypted message or the encrypted message received and pre-stored password When information is inconsistent, five anti-lock 109 unlocks will not be controlled, when again the state that control chip 116 receives the transmission of tongue tube 113 becomes Change signal, control chip 116 controls Alarm Unit 115 and alerts, prompts operation lack of standardization, there is leakage risk.

In summary：Firstly, five anti-lock 109 forced service personnel are according to set safe handling procedures, to electrical equipment It is correctly operated, to avoid the generation of misoperation fault, sufficiently meets " five is anti-" and require.Secondly, increasing electroscopic window Mouthful, operations staff can direct electrical verification, increase safety, reduce electrification and close the probability that the pernicious maloperation event of earthing knife-switch occurs. Finally, opening electrical verification luffer boards 105 by force when there is personnel not according to program, control chip 116 controls Alarm Unit 115 and alerts, mentions Show that operation is lack of standardization, has leakage risk, to reduce the probability of casualties, equipment damage.

The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
