In addition, like Fig. 6 or shown in Figure 8, according to a preferred version of the present disclosure, released strip assembly fixture 322 provides parts that can assemble secondary locking released strip 323 and the front side portion that can be arranged on supporting base 320.Released strip assembly fixture 322 can form integral body with supporting base 320, or combines through link and the supporting base 320 like screw.Released strip assembly fixture 322 has lower support pedestal and upper opening portion with assembling secondary locking released strip 323; And be set to the side of adjacent support pedestal 320; Thereby secondary locking released strip 323 is by the side support of supporting base 320, thereby can be formed with the front openings member.
With reference to figure 6 or Fig. 8, according to a preferred version of the present disclosure, the door interlock that is used for vacuum circuit-breaker can comprise further that secondary locking released strip 323 is to allow the user mutual with it in the position of adjacent support pedestal 320.
Secondary locking released strip 323 is assemblied on the released strip assembly fixture 322.In addition, when door was opened, secondary locking released strip 323 contacted with the bar main part 312 of securing rod 310, thereby the parts that can securing rod 310 be urged to the off-position are provided.
In other words; Open but because the external high pressure power circuit is not connected to support terminal 100a or breaker body 10 is in open position and therefore can guarantees under the state of user security at door 110; When the user hoped that breaker body 10 is transformed into link position (run location), secondary locking released strip 323 can be to be used for the parts that the artificially is urged to securing rod 310 off-position.
Simultaneously; With reference to figure 3 or Fig. 4; Thereby lock release lever 120 can be fixed and be arranged on door and 110 sentence towards locking mechanism 300 driven locking mechanisms 300, when door 110 is closed, locking mechanism 300 being contacted with the off-position, and when door 110 is opened, makes said locking mechanism 300 separation.
Simultaneously, below with main reference Fig. 9 and Figure 10 and subsidiaryly describe operation according to the door interlock that is used for vacuum circuit-breaker of a preferred embodiment of the present disclosure with reference to other accompanying drawings.
Suppose and describe such situation: be in breaker body 10 under the state of open position or test position, the user is transformed into run location with breaker body 10.
At first, at the door interlock that is used for vacuum circuit-breaker according to a preferred embodiment of the present disclosure, if door 110 is opened, then as shown in Figure 9, through the elastic force of bias spring 330, securing rod portion 313 is moved down into restriction site.
Therefore, barrier assembly 230 is positioned at the primary importance that connects the periphery of end 223 around the front end handle, thereby the front end handle that prevents axle 220 connects being connected between end 223 and the control crank (seeing the symbol H among Fig. 5).As a result, can not allow to connect end 223 and breaker body 10 is transformed into another position, therefore fundamentally protect the user to avoid the electrical safety accident through control crank H being connected to the front end handle.
Otherwise; At the door interlock that is used for vacuum circuit-breaker according to preferred embodiment of the present disclosure; If door 110 is closed; Then as shown in Figure 10, when the securing rod portion 313 of securing rod 310 moves up simultaneously when contact and being locked on the lower surface S that release lever 120 is squeezed in bar main part 312 with lock release lever 120, securing rod 310 moves to the off-position.
Therefore; If barrier assembly 230 is pushed by control crank H; Then barrier assembly 230 moves on direction backward to be positioned at the second place, exposes and the front end handle is connected end 223, thereby allows the front end handle of axle 220 to connect being connected between end 223 and the control crank H.As a result, the front end handle that control crank H is connected to axle 220 connects end 223, thereby allows breaker body 10 to be transformed into run location.
In the case, the user is by door 110 shielding, therefore, even externally high-voltage electric power circuit is connected to support terminal 100a and when being in conduction state, still can protects the user to avoid security incident safely.
