Because circuit breaker manipulation handle is tilt under gate-dividing state, so, when considering the vertical distance between manipulation handle and control model change lever, be as the criterion with the vertical distance manipulated between " root " of handle and control model change lever.So-called " root of manipulation handle ", refers to the position of manipulation handle near circuit breaker front.In addition, because manipulation tang portion self has certain vertical thickness, namely there is four edges edge up and down, so, when considering the vertical distance between circuit breaker manipulation handle and control model change lever, be as the criterion with the vertical distance manipulated between " the root top edge " of handle and control model change lever.
The present invention has the following advantages and effect:
One, before equipment box carries out testing or overhauling, can by two breaker open operations, control model change lever is pulled to the manual mode position on the left side, then snap close piece is latched in before two circuit breakers and control box, the left facade plate of snap close piece is made to abut in the front of control box, control model change lever then passes forward the first spacing hole and the second spacing hole, left plate and right plate laterally clamp control box protruding parts, left lockhole aims at right lockhole, the dead bolt of the second lockset protrudes upward and inserts right lockhole and left lockhole, and key is transferred to the second lock core of the second lockset, thus the locking realized circuit breaker and control box.After locking, because snap close piece just clamps trapezoidal control box protruding parts, therefore snap close piece can not move forward and backward, can not move left and right, the vertical position of snap close piece is then limited fixing by control model change lever, in a word, no longer can move in any direction after snap close piece locking, and after locking, control model change lever must be locked in manual mode position, therefore two circuit breakers can not carry out electric operating, and left facade plate and right facade plate hide fixing for the handle hole in control box front, therefore can not insert control lever and manual operation is carried out to two circuit breakers, and the manipulation handle of two circuit breakers is locked in open position, therefore guarantee in equipment box maintenance process, equipment box can not be charged.
Two, before equipment box overhauls, need to use key and open equipment box chamber door, mean that needs extract key from the second lock core of snap close piece, if now the operation of " by two breaker closings " is not just in case obtain implementing or operate miss, namely two circuit breakers wherein any one is in "on" position, after then hanging up snap close piece, the vertical position of snap close piece first spacing hole and the second spacing hole is inevitable higher than control model change lever, make control model change lever can not insert the first spacing hole and the second spacing hole, the end of control model change lever leans the inner surface of the left facade plate at snap close piece, force whole snap close piece biased forwards, and control box protruding parts is trapezoidal (lateral dimension of control box protruding parts is wider more forward), therefore the lateral separation between left plate and right plate can be forced to widen, and then make left lockhole can not aim at right lockhole, namely the dead bolt of the second lockset cannot protrude upward, second lockset cannot be locked, key cannot pull out away from the second lockset, therefore key can not be utilized to open equipment chamber door overhaul.Equally, before equipment box overhauls, if the operation of " manual mode position is pulled in control model change lever " is not just in case obtain implementing or operate miss, namely control model change lever is in automatically controlled mode position, when then hanging up snap close piece, left lockhole can not aim at right lockhole equally, and the second lockset cannot be locked, key cannot pull out away from the second lockset equally, key therefore can not be utilized to open equipment chamber door and overhaul.In a word, if any one of two circuit breakers is in "on" position, or control model change lever is in automatically controlled mode position, then " the second lockset can not be locked ", and linkage relationship reliability is high.The more important thing is, the present invention is before repair apparatus case, do not need to pay close attention to, implement multiple controlling unit, only should be noted and implement a controlling unit (this controlling unit is " whether the second lockset can be locked "), just can guarantee " overhaul front two circuit breakers separating brake, that control model change lever is positioned at manual position, control hole is covered ".Need owing to only having a controlling unit to implement, therefore control mode is very easy, alleviates the attentiveness burden of controllers, and significantly reduces the possibility of the error such as misoperation, erroneous judgement.
Three, in equipment box maintenance process, because equipment chamber door must be in open mode, mean that the door lock of equipment chamber door is in open mode, key is limited on the door lock of equipment chamber door, therefore the 3rd people can not utilize key to open the second lockset of snap close piece, the state of " overhaul separating brake, the control model change lever of front two circuit breakers and be positioned at manual position, control hole by left (right side) vertical panel covers " is made to there is no fear of being changed, linkage relationship reliability is high, guarantees maintenance process safety.
Above-mentioned 3 summaries are got up, and are exactly that the present invention can realize three guarantees: 1, ensure that equipment box is when only duplicate supply all disconnects at its upstream and circuit breaker is in manual mode just allows to open chamber door and carry out inspection operation; When 2, ensureing that equipment box carries out inspection operation, the key of snap close piece can only stay equipment chamber door; When 3, ensureing that equipment box carries out inspection operation, do not have the 3rd people of key upstream power supply cannot be closed a floodgate.In addition, snap close piece of the present invention is easy to use, the link of its working control has four (two circuit breakers, control hole, mode transitions handles), but need the control point paid close attention to diligently and definitely implement to only have one (" can the second lockset be locked "), and snap close piece operational motion is quite easy, when snap close piece being buckled control box, control model change lever only need be made to aim at the first (two) spacing hole, and do not need the aligned relationship requirement having other position again.

2.
Principle and the process of above-described embodiment formation linkage relationship are as follows:
Before needs to be tested equipment box or are overhauled, two breaker control handles 5 can be pivotally lowered into open position, control model change lever 66 is pulled to the manual mode position on the left side simultaneously, as shown in Figure 7, then snap close piece is latched in before two circuit breakers and control box, as Figure 20, Figure 21, Figure 22, shown in Figure 23, the left facade plate 11 of snap close piece is made to abut in control box front 62, left plate 12 and right plate 22 clamp control box protruding parts 61, left wing plate 13 abuts in the front of left side circuit breaker 4, right wing plate 23 abuts in the front of the right circuit breaker 4, control model change lever 66 then passes forward the first spacing hole 110 and the second spacing hole 210, left lockhole 140 aims at right lockhole 240, the dead bolt 28 of the second lockset 27 protrudes upward and inserts right lockhole and left lockhole, and key 74 is transferred to the second lock core 29 of the second lockset, thus the locking realized two circuit breakers 4 and control box 6.After the second lock core 29 key 74 being transferred to the second lockset, key 74 just can be utilized to open equipment box chamber door 71(door lock 72) overhaul.After snap close piece is locked, because snap close piece just clamps trapezoidal control box protruding parts 61, therefore snap close piece can not move forward and backward, can not move left and right, the vertical position of snap close piece then limits fixing by control model change lever 66, in a word, no longer can move in any direction after snap close piece locking, and after locking, control model change lever 66 must be locked in manual mode position, therefore two circuit breakers can not carry out electric operating, and left facade plate 11 and right facade plate 21 hide fixing for the handle hole 63 in control box front, therefore can not insert outer supporting control lever and manual operation is carried out to two circuit breakers, and manipulation handle 5 root of two circuit breakers is just by left wing plate 23, right wing plate 24 press against and can not upwards pull, be locked in open position, therefore guarantee in equipment box maintenance process, equipment box can not be charged.
Two, before equipment box 7 overhauls, need to use key 74 and open equipment box chamber door 71, mean that needs extract key from the second lock core 29 of snap close piece, so, if now the operation of " by two breaker closings " is not just in case obtain implementing or operate miss, namely two breaker control handles 5 wherein any one is in "on" position, namely a control handle 5 is in higher vertical position, after then hanging up snap close piece, the vertical position of the lower limb line 130 of left wing plate 13 or the lower limb line 230 of right wing plate 23 is inevitable higher than normal position, the vertical position of the first spacing hole 110 and the second spacing hole 210 is inevitable higher than control model change lever 66, make control model change lever 66 can not insert the first spacing hole 110 and the second spacing hole 210, the end of control model change lever 66 leans the inner surface of the left facade plate 11 at snap close piece, this will force whole snap close piece biased forwards (relative to normal latched position biased forwards), as shown in figure 24, and because control box protruding parts 61 is in trapezoidal (lateral dimension of control box protruding parts is wider more forward), therefore snap close piece biased forwards, the lateral separation between left plate and right plate can be forced to widen (for normal lock-out state), and then make left lockhole 140 can not aim at right lockhole 240, namely the dead bolt 28 of the second lockset cannot protrude upward, second lockset 27 cannot be locked, key 74 cannot pull out away from the second lockset, therefore can not take key away to open equipment chamber door and overhaul.Equally, before equipment box overhauls, if the operation of " manual mode position is pulled in control model change lever " is not just in case obtain implementing or operate miss, namely control model change lever 66 is in the automatically controlled mode position on the right, when then hanging up snap close piece, right fastener 2 is forced to depart from latched position to the right, as shown in figure 25, left lockhole can not aim at right lockhole equally, second lockset cannot be locked, key cannot pull out away from the second lockset equally, key therefore can not be utilized to open equipment chamber door and overhaul.In a word, if the operation of first does not obtain implementing or error, any one of i.e. two circuit breakers is also in "on" position, or control model change lever is also in automatically controlled mode position, then " the second lockset can not be locked ", therefore, the present invention is before repair apparatus case, do not need to pay close attention to, implement multiple controlling unit, only need implement a controlling unit (this controlling unit is " the second lockset can be locked "), just can guarantee " overhaul front two circuit breakers separating brake, that control model change lever is positioned at manual position, control hole is covered ".Need to pay close attention to owing to only having a controlling unit to implement, therefore alleviate the attentiveness burden of controllers, significantly reduce the possibility of the error such as misoperation, erroneous judgement.Even so, even if this uniquely needs the controlling unit paid close attention to not implemented, key also can only be followed at the second lockset, overhauls so also can not open equipment chamber door.
Three, in equipment box 7 maintenance process, because equipment chamber door 71 must be in open mode, mean that the door lock 72 of equipment chamber door is in open mode, key 74 is limited on the first lock core 73 of the door lock of equipment chamber door, therefore the 3rd people can not utilize key 74 to open the second lockset 27 of snap close piece, the state of " two circuit breakers separating brake, control model change lever are positioned at manual position, control hole by left (right side) vertical panel covers " that confirmed before making maintenance there is no fear of changing, further formation linkage relationship, guarantees maintenance process safety.
