Abstract
The utility model relates to a no operation and misoperation preventing device for electric power high voltage switches. A mercury switch is arranged on a main operating handle which is provided with a computer lock and the stroke of 120 DEG to 180 DEG pulling from top to bottom. The ' on ' and ' off ' of the mercury switch can be used for indicating the variation of the operating status and positions of the main operating handle. The variation can be added in the control program of the computer key to effectively prevent the no operation of the misoperation. The utility model has the advantages of simple and reliable structure and low cost.
Description
The utility model belongs to field of electrical equipment, is the power equipment auxiliary equipment.
Present existing high-voltage switch gear anti-misoperation apparatus has adopted the lock of computer key control, but how can not solve antiaircraft operational issue, even antiaircraft operating mechanism is arranged, also is complicated mechanical formula structure.
The purpose of this utility model is that a kind of manufacture craft of design is simple, is used for existing computer lock anti-misoperation apparatus, effectively solves the antiaircraft operational issue in the anti-misoperation.
Design of the present utility model is that it has public hole with lock (4) main operation handle (8), the lock body (6) of charged brain key socket (7), be subjected to computer key locking bar (5) control, that can insert lockhole (4), it also has the mercoid switch (1) that is installed on the main operation handle, and two binding posts (2) of this mercoid switch are connected on the socket (7) of computer key.This programme is applicable to that the main operation handle is from pulling to the equipment that 120～180 degree operational modes are arranged down.
The utility model has the advantages that simple in structurely, cost of manufacture is low, has effectively solved the antiaircraft operational issue in the computer lock anti-misoperation apparatus.

The utility model is described in further detail with following embodiment.
Embodiment 1, the air defense of high voltage isolator, anti-misoperation mechanism.
The main operation handle of high voltage isolator is as the operational mode shown in Fig. 1～4.To " closing " lock state of inductive switch, at this moment, mercoid switch is set is called one state when handle makes progress for " conducting ".Handle pulls 180 downwards when spending, and corresponding to isolating switch " branch " lock state, at this moment, mercoid switch becomes " disconnection " and is called " 0 " state.Two binding posts of mercoid switch are connected on the socket of computer key, make computer key can know that mercoid switch is to be in " conducting " or " disconnection ", or become " disconnection " by " conducting ", or become " conducting " by " disconnection ".That is to say and to know that mercoid switch and main operation handle are to be in one state or " 0 " state, or become " 0 " state, or become one state by " 0 " by " 1 ".This information is added in the program of computer key typing operation, just can effectively realizes the purpose of anti-do-nothing operation.Said " do-nothing operation " is meant, after the computer key release, do not have to carry out the operation to the main operation handle that promptly the state of main operation handle does not change.Operating process from four kinds of view of Fig. 1～4 can illustrate that how antiaircraft fool proof present embodiment is.Main operation handle among the figure is the main operation handle 1 of present embodiment isolating switch just, when it pulls to the top, and " combined floodgate " state of corresponding isolating switch, when pulling to the below, " separating brake " state of corresponding isolating switch.
Fig. 1 is the isolating switch state that " closes locking " just.Main operation handle (3) upwards is in " closing " position.Locking bar (5) inserts in the lockhole (4).Mercoid switch " conducting ", expression main operation handle is an one state.At this moment, the isolated switch main operating grip is locked, can't pull.
If there is order to need the isolating switch of above-mentioned " closing locking " is carried out " separating brake " operation, step is as follows:
[1] record there is the computer key of operation sequence inject in the computer key socket, locking bar (5) can be pulled out lockhole (4), Here it is " closing release " state shown in Figure 2, at this moment, handle still up, mercoid switch still is " conducting ", handle still is in one state, computer key is stuck, and can not take out.
[2] the main operation handle is pulled to the below " branch " position, mercoid switch becomes " disconnection ", and promptly the main operation handle becomes " 0 " state by " 1 ".Isolating switch " branch release " state of Here it is Fig. 3.
[3] again locking bar (5) is pushed in the lockhole (4), become isolating switch shown in Figure 4 and " divide and lock " state, just can take out computer key.
Finished aforesaid operations, computer key could take out, and carries out next command operation, and key is in the control program of computer key, the information of main operation handle state variation to be arranged, and just can carry out the operation of Next Command.This has just effectively prevented do-nothing operation (a kind of form of misoperation).
The antiaircraft anti-misoperation of the switching mechanism of embodiment 2. high voltage installation pocket doors.
Because of the main operation handle of the switching mechanism of pocket door how identical with the form shown in Fig. 1～4, then available design of the present utility model, on its main operation handle, adorn a mercoid switch, its binding post is received on the socket of computer key, and mercoid switch " led to " " breaking ", variation corresponding to " 1 " " 0 " signal is added in the control program of computer key, can effectively realize the antiaircraft anti-misoperation problem to pocket door, and its step and embodiment 1 are identical.
Claims (2)
1, a kind of power high voltage switch air defense, anti-misoperation apparatus, it has: the main operation handle in hole with lock, the locking bar that can insert lockhole that controlled by computer key, it is characterized in that: it also has the mercoid switch that is installed on the main operation handle.
2, power high voltage switch as claimed in claim 1 air defense, anti-misoperation apparatus is characterized in that: two binding posts of mercoid switch are connected on the socket of computer key.
