A permanent magnetic operation mechanism is used to be directly linked with the three vacuum interrupters through a vertical insulation pull rod. Or three moving contacts are uniformly arranged on the same circumference. Three static contacts are arranged above the three moving contacts. The permanent magnetic operation mechanism is used to be directly linked with the three moving contacts through the vertical insulation pull rod. Then, an insulation outer casing is used to seal the permanent magnetic operation mechanism, the three static contacts and the three moving contacts to be pumped into vacuum. Compared with the present permanent magnetic circuit breaker, the permanent magnetic switching circuit breaker has the advantages of strong rigidity, improved reliability, simplified structure, reduced volume and prolonged service life.
Description
Technical field
The utility model relates to a kind of power circuit breaker, and particularly a kind of permanent magnetism open-close type circuit breaker belongs to the power switch technology.
Background technology
Because the permanent-magnet operating mechanism part is few, and is simple in structure, service speed is fast, and energy consumption is very little, and the reliability height becomes the magneto circuit breaker so the gear lock button of traditional circuit breaker and electromagnetic type operating mechanism are replaced by permanent-magnet operating mechanism just gradually.Existing high-voltage permanent magnet type circuit breaker, its permanent-magnet operating mechanism mostly is connected in the lever mode with vacuum interrupter (the inside is a dynamic/static contact), especially drive three vacuum interrupters (every chamber Guan Yixiang) with a permanent-magnet operating mechanism, with a synchronous connecting rod three vacuum interrupters are linked together, be connected with permanent-magnet operating mechanism by leverage again, such breaker structure is compact inadequately, and a little less than this high-voltage permanent magnet type circuit breaker rigidity, volume is big.
Summary of the invention
The utility model purpose is to improve the rigidity of existing high-voltage permanent magnet type circuit breaker, thereby improves reliability, while simplified structure, reduced volume, life-saving.
The utility model is realized by following technical scheme.
Adopt me to obtain the driving mechanism of the permanent-magnet operating mechanism (its name is called " permanent magnetism closing device ", and the patent No. is ZL200520147440.6) of Chinese patent as described permanent magnetism open-close type circuit breaker.Primary cut-out requires contact (the moving iron core by permanent magnet mechanism drives) that higher just-off speed is arranged, and " permanent magnetism closing device " can satisfy this requirement well, and moving iron core is little to the base plate impulsive force during separating brake.First scheme: three vacuum interrupters are evenly arranged on the same circle, directly connect by vertically insulated pull bar with three vacuum interrupters with a permanent-magnet operating mechanism; Second kind of scheme: on same circumference, evenly arrange three moving contacts, three fixed contacts are directly over three moving contacts, directly connect by vertically insulated pull bar with three moving contacts with a permanent-magnet operating mechanism, with insulation crust they are all sealed then and be evacuated, such three-phase breaker becomes a big vacuum interrupter.
Useful effect:
1. the utility model is made driving mechanism with " permanent magnetism closing device ", moving unshakable in one's determination 6 interaction force of three moving contacts of circuit breaker and " permanent magnetism closing device " is distributed on moving unshakable in one's determination 6 upper surface simultaneously by top board 8 and push rod 10, the moving unshakable in one's determination 6 square effects that do not stress.If with other permanent-magnet operating mechanism, need a synchronising (connecting) rod will move iron core and directly be connected with the pull bar of moving contact or connect by leverage, so, synchronising (connecting) rod will be subjected to three moving contact reaction forces, so synchronising (connecting) rod will bear moment; If synchronising (connecting) rod is by leverage and moving unshakable in one's determination the connection, moving iron core also will bear moment loading, makes axis unshakable in one's determination axis tilt with respect to permanent-magnet operating mechanism, and this is harmful to permanent-magnet operating mechanism, and is also unfavorable to the interlock part of circuit breaker.So make driving mechanism than more excellent with other permanent-magnet operating mechanism with " permanent magnetism closing device ".
2. first kind of structure of described permanent magnetism open-close type circuit breaker, the pull bar 18 of its vacuum extinction chamber enclosure and moving contact is by bellows (not drawing among the figure) sealing that is flexible coupling, when circuit breaker is operated, bellows follows pull bar 18 up and down being pulled to lose the life-span of consuming oneself, so the life-span of vacuum interrupter is short.Second kind of structure of described permanent magnetism open-close type circuit breaker, remove the shell of vacuum interrupter, do not need bellows, three pairs of dynamic/static contacts and permanent-magnet operating mechanism are sealed in the vacuum, although what manufacturing cost might be than first scheme is higher, but its rigidity is higher, volume is littler, structure is simpler, and the life-span is long, is worthy to be popularized.
Generally speaking described two kinds of scheme moving contacts all directly connect with permanent-magnet operating mechanism by vertically insulated pull bar, than little, simple in structure, the low cost of manufacture of rigidity height, volume of existing high-voltage permanent magnet type circuit breaker.
