Abstract
The utility model relates to a low-voltage circuit breaker, one end in the shell is fixed with coil and quiet iron core, fixes on the push rod with coil and quiet iron core complex armature, and it is articulated with the lever that the shell stretches out to the push rod clearance ground, and the other end in the shell is fixed with the permanent magnet that corresponds with armature, the other end of lever articulated with vacuum interrupter's movable contact rod, the one end that is close to vacuum interrupter on the lever has the fulcrum. The driving power is small, the number of parts is small, the structure is simple, and the processing and the manufacturing are easy.
Description
The utility model relates to a kind of low-voltage circuit breaker.
Present domestic and international market, low-voltage circuit breaker mostly adopts the air type circuit breaker to be equipped with the spring electromagnetic mechanism, and its shortcoming is that driving power is bigger, and amount of parts is many, complex structure, the big formation of making current or drop-out current arc light is polluted.
The purpose of this utility model is to design that a kind of driving power is less, amount of parts is few, the low-voltage intelligent bistable permanent magnetic vacuum circuit-breaker of simple in structure, easy processing and manufacturing.
The utility model is achieved in that the end in the shell is fixed with coil and fixed core, the armature that cooperates with coil and fixed core is fixed on the push rod, stretch out shell to the push rod clearance and lever is hinged, the other end in the shell is fixed with the permanent magnet corresponding with armature, the other end of described lever and the movable feeler lever of vacuum interrupter are hinged, and the end near vacuum interrupter on the lever has fulcrum.
The utility model compared with prior art has following advantage: (1), since the vacuum interrupter dielectric strength very high, the arc extinguishing ability is strong, contact travel is little, so driving power is little; (2), few, simple in structure, the easy processing and manufacturing of amount of parts; (3), branch and lock process finish in the enclosed vacuum arc control device, so electric arc does not expose, also do not have the outside splash of gas of heat, do not pollute the environment, and also can not cause fire or blast, can work anywhere; (4), because the vacuum interrupter rate of wear is little, so the life-span is long, is particularly suitable for the place of frequent operation; Because coil is i.e. outage behind combined floodgate, scaling loss has also been saved electric energy so coil differs.
Be elaborated below in conjunction with accompanying drawing.
Accompanying drawing is the utility model structural representation.
Upper end fixed coil and fixed core 5 in the shell 7, the armature 6 that cooperates with coil and fixed core 5 is fixed on the push rod 9, and push rod 9 upwards stretches out shell 7, fixed reset spring 4 between shell 7 and push rod 9 with gap.Push rod 9 stretches out shell 7 and hinged with lever 3 downwards with gap.The fixing permanent magnet 8 corresponding of the other ends in the shell 7 with armature 6.The other end of described lever 3 and buffer 2 are hinged, and the end near vacuum interrupter 1 on the lever 3 has fulcrum.Push rod 11 and buffering spring 10 are arranged in the described buffer 2, and the movable feeler lever of the upper end of push rod 11 and vacuum interrupter 1 is fixed, and the lower end is sitting on the buffer spring 10, and buffer spring 10 lower ends are pressed in the intracavity bottom of buffer 2.During combined floodgate, the power supply of closing coil, coil and fixed core 5 produce magnetic field, with armature 6 magnetization and downward the promotion near permanent magnet 8.Because armature 6 is opposite with the magnetic of permanent magnet 8 contact portions, so armature 6 inhaled fast down and held, and the push rod of fixing with armature 69 also moves down.Meanwhile, lever 3 downward left end of right-hand member under the effect of push rod 9 is upwards slippaged the normally opened contact of vacuum interrupter 1 by buffer 2, and institute's control circuit promptly is switched on.After institute's control circuit promptly was switched on, because the suction-operated of permanent magnet 8, coil can cut off the power supply, and has saved electric energy.Gate separating type, give the coil reverse current, coil and fixed core 5 produce the opposing magnetic field, armature 6 be reversed the magnetization and identical with permanent magnet 8 magnetic, under the acting in conjunction of coil and fixed core 5 and permanent magnet 8, armature 6 and push rod 9 make progress fast, by lever 3 and buffer 2 vacuum interrupter 1 are resetted, and institute's control circuit promptly is disconnected.
