Detailed description of the invention
This utility model preferred embodiment is provided, to describe the technical solution of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the axonometric chart of the schematic diagram of overall cabinet in this utility model.Fig. 2 is the axonometric chart of the structural representation at the middle door back side.As illustrated in fig. 1 and 2: this utility model provides lock support 3 to be arranged on the middle door 2 of switch device cabinet bodies 1, and middle door 2 is arranged on global switch equipment cabinet 1, is provided with handcart circuit breaker 4, handcart circuit breaker 4 is provided with latch hook 5 in switch device cabinet bodies 1.
Fig. 3 is the axonometric chart of the lock support at the middle door back side.As illustrated in fig. 1 and 2: the lock support 3 in this utility model includes: cross section is the metallic plate of " L " shape, the one side of metallic plate is close to middle door, another side vertical centering control door, the face 302 of vertical centering control door is fixed with lock 304, it is close on the face 301 of door porose 303, in the implementation process that this utility model is concrete, hole 303 is generally screwed hole, adopts Bolt through holes 303 to be fixed on middle door in the face 301 being close to middle door.
In concrete utilization process, latch hook 5 and lock 304 support the use.In the implementation process that this utility model is concrete, whole lock support 3 adopts one block of plate one-body molded, not only easy to make, and total intensity is high.
Fig. 4 is the left view of overall cabinet, and Fig. 5 is the view in the A-A direction of Fig. 4, and Fig. 6 is the view in the B-B direction of Fig. 4.As Figure 4-Figure 6: the handcart circuit breaker 4 in this utility model is arranged on the position in switch device cabinet bodies 1 near middle door.
Fig. 7 is the handcart circuit breaker structural representation in testing position.Fig. 8 is the handcart circuit breaker structural representation in operating position.As can be seen from Figures 7 and 8, the relative position of handcart circuit breaker 4 and chassis 6 has movement, and in Fig. 8, the position of handcart circuit breaker 4 more keeps left, and during operating position, handcart circuit breaker 4 is away from middle door 2.
Fig. 9 is handcart circuit breaker chassis inside top figure, Figure 10 is the E place enlarged drawing of Fig. 9.
As shown in Figures 9 and 10: " A " place in Fig. 9 and 10, now latch hook 5 is expressed as latch hook released state (when handcart circuit breaker is in testing position)." B " place in Fig. 9 and 10, now latch hook 5 represents latch hook blocking (when handcart circuit breaker is in operating position)." C " place in Fig. 9 and 10, is now travel switch released state (when middle door is closed, handcart can shake into shaking out)." D " place in Fig. 9 and 10, is now travel switch blocking (when middle door is opened, handcart can not shake into shaking out).
Middle door 2 is closed when putting in place, and middle door face board top pressure travel switch unlocks, and now handcart circuit breaker operation handle is operated by hole 201, rotates handcart and shakes and make handcart circuit breaker testing position retreat to testing position to operating position or operating position into shaking out handle；Travel switch reset lockout state when middle door is opened, handcart circuit breaker shakes into shaking out locked, and operation handle can not be operated by hole and shake into shaking out chopper (can not make handcart circuit breaker testing position to operating position).
Figure 11 is when handcart circuit breaker is when testing position, and middle door is by carrying the structural representation of door in a mechanism lifts.Figure 12 is the structural representation that handcart circuit breaker latch hook is in the locked position.Join the handcart type breaker (chassis of handcart type breaker must be equipped with and the latch hook of cabinet gate interlock) of metal armored withdrawal-type switching device, when handcart circuit breaker is when testing position, the middle door of Ti Men mechanism is by carrying door in a mechanism lifts, see Figure 11, now the latch hook of circuit breaker cart is unlocked position (failing to hook lock support), middle door is closed the lock pin dropping place putting and making middle door in place in the groove of left and right protective plate, middle door is closed and is put in place, shake now by the handle hole 201 of middle door and handcart circuit breaker is in operating position into shaking out handle, now handcart circuit breaker latch hook is in the locked position (latch hook hooks lock support) and sees Figure 12, now door cannot be opened.
This utility model provides door in the locking anti-misoperation of switchgear shift mechanism, coordinates one to join metal armored removal type sealed switch equipment shift mechanism locking anti-misoperation gate interlock structure；Solve lever gear door structure handcart circuit breaker and shelter-clad removal switch cabinet cabinet interlocking problem smoothly, enhance switch cubicle " 5 prevent " Interlock Function, enhance reliability and safety.
