Description
Technical field
The utility model relates to a kind of electric power vacuum circuit-breaker, and is special relevant with a kind of permanent magnetic actuator vacuum circuit breaker.
Background technology
Its operating mechanism of conventional high-tension vacuum circuit-breaker mainly adopts spring mechanism, many, the complex structure of parts, thereby the source of trouble is many, and long-term frequent operation, the failure rate height, dependability is poor, and maintenance workload is big.Mainly few, the reliable in action of motion parts, combined floodgate characteristic cooperate than advantage such as traditional operating mechanism is better and receive much attention the permanent magnetic actuator vacuum circuit breaker of Chu Xianing with vacuum circuit-breaker with it in recent years.But present permanent magnetic actuator vacuum circuit breaker only depends on a connecting lever in the transmission of power, and efficient is not high, has brought more problem also for simultaneously the control section of permanent magnet mechanism.
The utility model content
The utility model mainly provides a kind of available less exerting oneself and keeps bigger contact confining force, the permanent magnetic actuator vacuum circuit breaker that efficient is higher.
The technical solution adopted in the utility model is: at the big connecting lever right-hand member hinged of permanent magnetic actuator vacuum circuit breaker in flakes, be hinged with two connecting levers on the framework macro-axis, be hinged with a connecting lever in flakes, and each opposite position of circuit breaker is this articulated structure, a hinged connecting plate on another connecting lever, the lower end of connecting plate and another connecting lever and support plate are articulated in a free bearing pin, the right-hand member of this connecting lever is hinged with the bearing pin that is fixed on the framework, the upper end of support plate is hinged with a drive rod, and drive rod can move up and down under the driving of permanent magnet mechanism.Like this insulated tension pole, big connecting lever, form quadric chain with connecting lever in flakes.
The quadric chain permanent magnetic actuator vacuum circuit breaker that the utility model provides is after combined floodgate is finished, a closing retention force part has decomposed on the macro-axis, another part power relies on permanent magnet mechanism to finish, so just improved the efficient of permanent magnet mechanism, the mechanism reliability height, failure rate is low, can frequent operation.
Description of drawings
Fig. 1 is the structural representation of an embodiment of permanent magnetic actuator vacuum circuit breaker when closing position of the utility model band quadric chain;
Fig. 2 is the structural representation when the separating brake position embodiment illustrated in fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, pole 2, insulated tension pole 3, big connecting lever 4, bearing pin 5, link plate 6, tripping spring 7, macro-axis 8, connecting lever 9, connecting plate 10, framework 11, bearing pin 12, connecting lever 13, support plate 14, drive rod 15, connecting plate 16, connecting lever 17, permanent magnet mechanism 18, vacuum interrupter
As shown in the figure, present embodiment is the permanent magnetic actuator vacuum circuit breaker of a band quadric chain, and vacuum interrupter 18 usefulness epoxy resin seal admittedly and form pole 1, are fixed in the bottom of framework 10 by screw thread.Insulated tension pole 2 is positioned at the lower end of vacuum interrupter 18 and uses nut fastening.The left end of big connecting lever 3 is connected with the lower end of insulated tension pole 2, and big connecting lever 3 bodies place in the framework 10, and its middle part is provided with a circular hole.Bearing pin 4 places this circular hole and hinged with framework 10, and big connecting lever 3 can rotate around bearing pin 4.An end of 9 is hinged with the right-hand member of big connecting lever 3 in flakes, and the connecting lever 8 on 9 the other end and the macro-axis 7 is hinged in flakes.Macro-axis 7 is provided with another connecting lever 16 and hinged with the upper end of connecting plate 15, and the left end of the lower end of connecting plate 15 and connecting lever 12, the lower end of support plate 13 are articulated in a free bearing pin.The right-hand member of connecting lever 12 is hinged with the bearing pin 11 that is fixed on the framework 10.The upper end of support plate 13 and drive rod 14 lower ends are hinged, and drive rod 14 can move up and down under the driving of permanent magnet mechanism 17.Be provided with a link plate 5 directly over the right-hand member of big connecting lever 3, the upper end of tripping spring 6 is connected with link plate 5, and the lower end hangs on the big connecting lever 3.
When circuit breaker need close a floodgate, the coil of permanent magnet mechanism 17 is charged, order about drive rod 14 and move downward, drive support plate 13, connecting plate 15 and connecting lever 16 and rotate, the rotation of connecting lever 16 can be ordered about macro-axis 7 and clockwise rotate, the connecting lever 8 that the rotation of macro-axis 7 simultaneously can drive each phase rotates, connecting lever 8 pushes down in flakes 9 downwards, forces big connecting lever 3 right-hand members to move downward, and spring 6 is stretched, big connecting lever 3 left ends move upward, and make the dynamic/static contact closure of vacuum interrupter 17 finish the operation of combined floodgate.Wherein insulated tension pole 2, big connecting lever 3, in flakes 9 and connecting lever 8 formed quadric chain, close a floodgate finish after, a closing retention force part has decomposed on the macro-axis 7, another part power relies on permanent magnet mechanism 17 to finish, and has so just improved the efficient of permanent magnet mechanism.
