Abstract
The utility model provides a permanent magnetic mechanism for outdoor pole -mounted circuit -breakers, including running through permanent magnetic mechanism's drive shaft, with the left end board, right end board and the upper head plate that move iron core and symmetric distribution both sides about the drive shaft of drive shaft joint, drive shaft, left end board, right end board and upper head plate surround into an accommodation space the permanent magnet and the solenoid that link to each other with the upper head plate surface set gradually in the accommodation space in left end board to right end board direction solenoid is close to left end board one side and still is provided with quiet iron core respectively. The beneficial effects of the utility model are that need not mechanical dropout, locking device, permanent magnetic mechanism that the fault source is few, the reliability is high.
Description
Technical field
The utility model belongs to power distribution automation equipment technical field, especially relates to a kind of Standard type circuit breaker permanent magnet mechanism.
Background technology
Because permanent magnet mechanism has, structure height simplifies, energy-conservation and high reliability, and the electromagnetism actuating, the permanent magnetism that can be good at pressure vacuum switchgear in meeting keep and Electronic Control requirement, thus obtains comparatively general application.Nonetheless, the space that traditional permanent magnet mechanism still has greatly improved, the permanent magnet mechanism as traditional needs that mechanical trip and locker, the source of trouble are more, dispersion operate time and uncontrollable etc.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of without the need to mechanical trip, locker, the permanent magnet mechanism that the source of trouble is few, reliability is high.
The technical solution of the utility model is: a kind of Standard type circuit breaker permanent magnet mechanism, comprise run through described permanent magnet mechanism driving shaft, with the dynamic iron core of driving shaft clamping and be symmetrically distributed in the first member plate of the upper and lower both sides of driving shaft, right end plate and upper head plate, described driving shaft, first member plate, right end plate and upper head plate are encircled into an accommodation space, in described accommodation space, on first member plate to right end plate direction, be disposed with the permanent magnet and solenoid that are connected with superior endplate surface, be also respectively arranged with static iron core at described solenoid near first member plate side.
Further, described first member plate, right end plate and upper head plate adopt aluminium sheet material to make.
Further, the below of described right end plate is provided with banking pin.
The advantage that the utility model has and good effect are: the utility model is simple and reliable for structure, and electric control loop is simple, and compared with prior art, the life-span is longer, and cost is lower, and interchangeability is good.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
As shown in Fig. 1-Fig. 2 the utility model structural representation, the utility model provides a kind of Standard type circuit breaker permanent magnet mechanism, comprise the driving shaft 1 running through described permanent magnet mechanism, with the dynamic iron core 2 of driving shaft 1 clamping, and be symmetrically distributed in the first member plate 3 of driving shaft about 1 both sides, right end plate 4 and upper head plate 5, described driving shaft 1, first member plate 3, right end plate 4 and upper head plate 5 are encircled into an accommodation space, on first member plate 3 to right end plate 4 direction, the permanent magnet 6 and solenoid 7 that are connected with upper head plate 5 surface is disposed with in described accommodation space, static iron core 8 is also respectively arranged with near first member plate 3 side at described solenoid 7.Described first member plate 3, right end plate 4 and upper head plate 5 adopt aluminium sheet material to make.The below of described right end plate 4 is provided with banking pin 9.
The course of work of this example: the Standard type circuit breaker permanent magnet mechanism that the utility model provides, be in gate-dividing state at the beginning as shown in Figure 1, when carrying out electric switch-on, solenoid 7 is energized, the magnetic field produced and permanent magnet 6 magnetic field superposition, dynamic iron core 2 produces thrust under field drives, due to dynamic iron core 2 and driving shaft 1 clamping, so dynamic iron core 2 drives driving shaft 1 to release forward, the traction casing arranged by driving shaft 1 front end is promoted deciliter swing arm and carries out closing operation, also compressed energy-storage is carried out to energy-stored spring simultaneously, combined floodgate puts in place as shown in Figure 2, solenoid 7 power-off.After combined floodgate puts in place, dynamic iron core 2 contacts with right end plate 4, together with cylinder body, permanent magnet 6 and static iron core 8 together form closed magnetic circuit, magnetic gap is zero, only the magneticaction of permanent magnet 6 just can make both adhesive self-lockings, and the separating brake power that this power produces much larger than energy-stored spring, thus a deciliter swing arm is locked to "on" position, when carrying out electronic separating brake, solenoid 7 is oppositely energized, magnetic field and permanent magnet 6 magnetic field offset, permanent magnetism self-lock force disappears, under the earth pressure release effect of energy-stored spring, sub-switching operation is carried out in deciliter swing arm, after separating brake puts in place, deciliter swing arm is pressed in banking pin 9 place by energy-stored spring, be locked in separating brake shape.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
