Description
Technical field
The utility model relates to a kind of interlock limiting circuit breaker and isolating switch operating sequence when operating.
Background technology
Interlock object between circuit breaker and isolating switch is the proper operation order ensured between circuit breaker splitting or integrating lock and isolating switch splitting or integrating lock, avoids operate miss accidents caused, ensures the person and device security.Most high-tension switch cabinet device interrupt road device and isolating switch installation site are arranged nearer, interlocking realizes convenient, and when the spacing of circuit breaker and isolating switch is inevitably arranged far away, chain conversion links between it can correspondingly increase, the complexity of interlocking certainly will be added, reduce reliability
.
Utility model content
The purpose of this utility model is to provide with interlock between a kind of circuit breaker and isolating switch, when solving distant between circuit breaker and isolating switch, and the problem that interlocking is complicated, reliability is low.
For achieving the above object, the utility model is by the following technical solutions: with interlock between a kind of circuit breaker and isolating switch, comprise baffle plate, operating axis, breaker mechanism, closing magnet master part, closing locking device, cam, making electromagnet push rod, circuit breaker transmission macro-axis, baffle plate is positioned at the front end of operating axis, circuit breaker transmission macro-axis and closing magnet master part are located on breaker mechanism, closing locking device is connected with closing magnet master part, cam rests on closing magnet master part, making electromagnet push rod is right against the front of closing magnet master part, it also comprises the slide rail of fixed dam, with baffle plate interlock interlock plate, spacing connecting lever, transmission crank arm, baffle plate is connected by connecting rod with interlock plate, spacing connecting lever and transmission crank arm coaxial sleeve are located on circuit breaker transmission macro-axis, spacing connecting lever is equipped with pin, interlock plate and closing locking device pass through pinned connection, interlock plate rests on spacing connecting lever.
The beneficial effects of the utility model: limit the operating sequence between circuit breaker and isolating switch, i.e. " point circuit breaker-point isolation-close isolation-conjunction circuit breaker ", namely need during cutoff circuit first to divide circuit breaker, separate isolating switch afterwards, circuit breaker could be closed after first closing isolating switch when connecting loop, and possess blocking function in operation, namely can not disconnecting switch operation when circuit breaker is in "on" position, otherwise isolating switch can not operating breaker at open position, improve the fail safe of operation.Simple, convenient but achieve the function of operating sequence and mutually locking, structure is simple and clear, amount of parts is few.The utility model utilize a kind of simple interlock realize circuit breaker and isolating switch installation site far away time proper operation order, improve the unfailing performance of product.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
With interlock between a kind of circuit breaker and isolating switch, comprise baffle plate 1, operating axis 6, breaker mechanism 15, closing magnet master part 8, closing locking device 14, cam 13, making electromagnet push rod 7, circuit breaker transmission macro-axis 11, baffle plate 1 is positioned at the front end of operating axis 6, circuit breaker transmission macro-axis 11 and closing magnet master part 8 are located on breaker mechanism 15, closing locking device 14 is connected with closing magnet master part 8, cam 13 rests on closing magnet master part 8, making electromagnet push rod 7 is right against the front of closing magnet master part 8, it also comprises the slide rail 2 of fixed dam 1, with baffle plate 1 interlock interlock plate 4, spacing connecting lever 10, transmission crank arm 12, baffle plate 1 is connected by connecting rod 3 with interlock plate 4, spacing connecting lever 10 and transmission crank arm 12 coaxial sleeve are located on circuit breaker transmission macro-axis 11, spacing connecting lever 10 is equipped with pin 9, interlock plate 4 is connected by bearing pin 5 with closing locking device 14, interlock plate 4 rests on spacing connecting lever 10, interlock plate and baffle plate synchronously slide up and down, spacing connecting lever 10 can rotate with circuit breaker transmission macro-axis 11, transmission crank arm is connected with circuit breaker major loop by mechanical connecting structure.The following side of interlock plate 4 is provided with crimp 17, and crimp 17 is positioned at immediately below pin 9.
The utility model specific works principle is as follows: Fig. 3 and Fig. 4 shows circuit breaker and be in "on" position: breaker mechanism making electromagnet push rod 7 promotes closing magnet master part 8, closing magnet master part 8 turns to position shown in dotted line in figure, the cam 13 stopped thereon is thrown off, cam 13 turns to dotted line position in figure immediately, knock transmission crank arm 12 in rotation process, transmission crank arm 12 rotating band is moved the rotation of circuit breaker transmission macro-axis 11 and is made breaker closing.Rotate A position to figure with the coaxial sheathed fixing spacing connecting lever 10 of transmission crank arm 12, the crimp pushing down correspondence position on interlock plate 4 by the pin 9 on it makes it can not upward sliding.Because the interlock plate 4 coupled baffle plate 1 blocking isolator operation macro-axis 6 that can not slide just can not be moved, thus reach circuit breaker can not the object of disconnecting switch operation at closing position.
Fig. 5 and Fig. 6 shows circuit breaker and is in gate-dividing state: circuit breaker circuit breaker transmission macro-axis 11 when gate-dividing state rotarily drives the sheathed spacing connecting lever 10 be fixed thereon and rotates position to Fig. 5, the crimp of correspondence position on interlock plate 4 no longer pushed down by pin 9 on spacing connecting lever 10, make interlock plate 4 can upward sliding, because the interlock plate 4 coupled baffle plate 1 blocking isolator operation macro-axis 6 that can slide just can upwards promote, thus operating grip 16 can insert isolator operation macro-axis 6 enterprising line operate is opened by isolating switch, realize the order of " point circuit breaker---point isolation ", baffle plate 1 can not fall due to the stop of operating grip 16, interlock plate 4 position be connected by connecting rod 3 with baffle plate 1 keeps motionless, breaker closing locking device 14 is lifted to the blocking function of shown position due to circuit breaker design by interlock plate 4 lower end bearing pin 5, now the position of closing magnet master part 8 is limited, cam 13 is stopped can not rotate, transmission crank arm 12 can not be knocked, circuit breaker transmission macro-axis 11 can not be driven to rotate thus circuit breaker can not be closed a floodgate, thus reach isolating switch can not the object of operating breaker at operating position.Realize the order of " closing isolation-conjunction circuit breaker " simultaneously.Generally speaking realize the operating sequence of " point circuit breaker---point isolation-conjunction isolation-close circuit breaker ".
