Abstract
The utility model relates to the technical field of vacuum circuit breakers, in particular to an interlocking mechanism of a permanent magnet vacuum circuit breaker, which comprises a connecting plate, a rotary shaft, a crank arm, a push plate, an interlocking plate and a chassis. One end of the push plate is connected with a rotary plate on the chassis through a rotating pin, the other end of the push plate is rotatably connected with the crank arm which is fixed to the rotary shaft and capable of rotating along with the rotary shaft, the connecting plate and the crank arm are both connected with the interlocking plate via interlocking pins, the interlocking plate is fixed onto a support plate through a pin and capable of rotating around the pin, the other end of the interlocking plate extends to the position of an input crank arm below a permanent magnet and is capable of interfering with the input crank arm in a crossing manner. The interlocking mechanism is simple in structure and reliable in performance and meets the requirement of versatility.
Description
Technical field
The utility model relates to a kind of vacuum circuit-breaker technical field, especially a kind of interlocking device of permanent magnetism vacuum circuit-breaker.
Background technology
The electric misoperation of high-voltage switch gear causes accidents such as power equipment damage, system blackout even casualties easily.Existing interlocking realize with regard to require machinery and electric aspect require all to realize that the scheme of interlocking has a lot, function also can meet the demands, but the interlocking gear of existing handcart-type permanent magnetism vacuum circuit-breaker is to lean on the mode of electrical equipment control to realize substantially, if electric elements damage or line fault causes accident easily, therefore, we adopt a kind of novel interlocking device, and breaker mechanism is connected with advancing handcart, make it increase mechanical interlocking control, it is complete that its function is able to.
The utility model content
Be better meeting the market requirement, the utility model provides a kind of interlocking device of handcart-type formula vacuum circuit-breaker, can realize handcart-type permanent magnetism vacuum circuit-breaker mechanical anti-misoperation function, complete realization the machinery and the interlock of electric aspect.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of interlocking device of permanent magnetism vacuum circuit-breaker, this mechanism is mainly by connecting plate, rotating shaft, connecting lever, push pedal, interlock plate, the chassis car is formed, push pedal one end links to each other by rotatable pin with rotating disk on the car of chassis, and the other end and connecting lever are rotationally connected; Connecting lever is fixed in the rotating shaft, can rotate with rotating shaft, and connecting plate all adopts rotatable pin to be connected with connecting lever and interlock plate; Interlock plate can rotate around pin by on the pin fixed support plate, and the other end of this interlock plate extends to the input connecting lever place of permanent magnet below, but chiasma interference.
Described connecting lever is a L shaped right angle connecting lever.
The beneficial effects of the utility model are: handcart-type permanent magnetism vacuum circuit-breaker adopts the utility model interlocking device, and is simple in structure, dependable performance, and it satisfies the requirement of complete function.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structure chart: circuit breaker can not close a floodgate, and the chassis car can seesaw;
Fig. 2 is the utility model structure chart: but the circuit breaker on/off switch, and the chassis car can not seesaw.
Among the figure: 1. connecting plate, 2. rotating shaft, 3. connecting lever, 4. push pedal, 5. rotating disk, 6. permanent magnet, 7. input connecting lever, 8. interlock plate, 9. pin, 10. chassis car.
Embodiment
As shown in Figure 1, 2, a kind of interlocking device of permanent magnetism vacuum circuit-breaker, this mechanism be mainly by connecting plate 1, rotating shaft 2, connecting lever 3, push pedal 4, interlock plate 8, chassis car 10 is formed, and rotating disk on push pedal 4 one ends and the chassis car 10 5 links to each other by rotatable pin, and the other end and connecting lever 3 are rotationally connected; Connecting lever 3 is fixed in the rotating shaft 2, can rotate with rotating shaft 2, and connecting plate 1 all adopts rotatable pin to be connected with connecting lever 3 and interlock plate 8; Interlock plate 8 can rotate around pin 9 by on pin 9 fixed support plates, and the other end of this interlock plate 8 extends to input connecting lever 7 places of permanent magnet 6 belows, but chiasma interference.
Described connecting lever 3 is a L shaped right angle connecting lever.
As shown in Figure 1, when chassis car rotating disk 5 clockwise rotates certain position, drive push pedal 4 and upwards rotation of connecting lever 3, thereby impel connecting plate 1 to move right, cause interlock plate 8 to be rotated counterclockwise to permanent magnet 6 belows, prop up input connecting lever 7, circuit breaker can not close a floodgate, and the chassis car can drive circuit breaker and shook into and shake out this moment;
As shown in Figure 2, after circuit breaker is shifted the fixed position onto, when chassis car rotating disk 5 is gone to the below, pulling push pedal 4 and connecting lever 3 rotate, thereby impel connecting plate 1 to be moved to the left, and cause interlock plate 8 whiz permanent magnets 6 belows, but input connecting lever 7 knee-actions, circuit breaker can carry out the on/off switch operation.
