Abstract
The invention relates to a permanent magnetism mechanism, which comprises an upper case body and a lower case body, wherein, a movable core is arranged between the upper case body and the lower case body; the upper part of the movable core is provided with three upper guide levers. Both sides of the upper guide lever positioned at the middle are provided with a tripping spring and a tripping spring adjusting screw. The upper part of the upper guide lever is provided with an insulator and a contact spring. The position where the lower part of the movable core corresponds to the upper guide lever is provided with a hand trip gear, and both sides of the movable core are provided with a closing coil and a permanent magnet. The invention has the advantages that linear drive is realized on a three step switch tube and the synchronicity and the operability of the three step action are more reliable; the adjustment of the speed of a trip also can be realized; the structure is simple; the cost is low. The invention can be widely used for a breaker and a contactor of a mine feed system, and the environment of the mine feed system is vile, and the mine feed system has high requirement for the reliability. Because the invention only adopts one closing coil, the space of the closing coil is increased. The number of turns of the closing coil can be increased on the premise that the coil diameter is the same or greater than the diameter of the primary coil. The invention can realize frequent electrification for a long time and can not be burnt under the condition that ampere-turn is invariable or the ampere-turn is properly enhanced.
Description
Technical field
What the present invention relates to use in high, medium and low voltage breaker, the contactor in a kind of electric power system is provided with by same moving iron core and many unicoil permanent magnet mechanisms that switching tube linearly drives.
Technical background
The permanent magnet mechanism that uses in high, medium and low voltage breaker, the contactor in the electric power system at present generally is that every switching tube is realized Synchronization Control or realized a plurality of switching tubes of driven in synchronism by a permanent magnet mechanism by rotating connecting lever by a permanent magnet mechanism linear drives and by electronic technology.The former technical difficulty is big and technology is also immature, can't use in the occasion that product price is lower; The latter need increase guider could realize linear drives, and so not only complex structure, energy loss are also very big, and functional reliability, stability are far away from linear drives.
In order to address the above problem, provide a kind of " permanent-magnet breaker " in the Chinese patent of " 200620023760.5 " in the patent No..Owing to adopt combined floodgate solenoid and separating brake solenoid in the permanent-magnet breaker upper and lower part, the design of closing coil mostly is instantaneous duty, make the power and the structure space of closing coil limited, closing coil can't be designed to the solenoid of long-term work under the prerequisite that produces same electromagnetic intensity.At frequent operation or the situation that closing coil is burnt under some failure condition occurs and happen occasionally, especially under the mine explosion-suppression situation, use and give the very big influence of ordinary production like this.
Summary of the invention
The objective of the invention is to solve the problem that prior art exists, a kind of applied widely, simple in structure, dependable performance, cheap is provided, but frequent operation and do not damage the permanent magnet mechanism of coil.
The present invention is achieved in that it comprises upper shell 2 and lower house 6, between upper shell 2 and lower house 6, be provided with moving unshakable in one's determination 3, be provided with guide post 1 on three on moving 3 tops unshakable in one's determination, guide post 1 both sides are provided with tripping spring 13 and sluice separating spring adjustment jackscrew 11 in the middle of being positioned at, on last guide post 1 top insulator 9 and contact spring 10 are installed, be provided with hand trip gear 7 in moving 3 bottoms unshakable in one's determination with last guide post 1 correspondence position, its special character is: be provided with a closing coil 4 and permanent magnet 5 in moving 3 both sides unshakable in one's determination.
Above-mentioned permanent magnet mechanism, described hand trip gear 7 are one and corresponding with last guide post 1 position in the middle of being positioned at, and owing to having cancelled two following guide posts, can make that structure is simpler, cost is cheaper.
Advantage of the present invention is: make the synchronism of three grades of actions, operability more reliable when the three step switch pipe is realized linear drives, make microscler moving iron core stress balance and can realize the adjustment of opening velocity; And simple in structure, with low cost, can be widely used in environment abominable, to circuit breaker and contactor in the higher mining feed system of reliability requirement.Owing to only adopt a closing coil, close a floodgate during logical forward electricity, during logical oppositely electricity with tripping spring acting in conjunction realization separating brake; The closing coil space increases, and under identical or prerequisite greater than former line footpath, can increase coil turn, has realized long-term frequent energising under the situation of or suitable raising constant at number of ampere turns and does not burn coil, so dependable performance, and saved copper material, save the space.

Embodiment
As shown in the figure, the present invention includes upper shell 2, lower house 6, be provided with the moving iron core 3 of strip in upper shell 2, lower house 6, be fixed with three top guide bars 1 on moving iron core 3 tops, top guide bar 1 is passed by upper shell 2; Top guide bar 1 bilateral symmetry in the middle of being positioned on the moving iron core 3 is provided with two tripping springs 13, and tripping spring 13 upper ends are connected with tripping spring jackscrew 11, tripping spring 13 can be adjusted locking by tripping spring jackscrew 11; On moving iron core 3, be set with closing coil 4,4 times permanent magnet 5 be housed, more than form the basic element of character of permanent magnet mechanism at closing coil.On last guide post 1, insulator 9 and contact spring 10 are installed by bearing pin 12, guide post 1 correspondence position is equipped with hand trip gear lower guide rod 8 and hand trip gear 7 in moving 3 bottoms unshakable in one's determination and in the middle of being positioned at, and complete driving is closed, the permanent magnet mechanism of separating brake thereby form.
During work, move and compress tripping spring 13 when iron core 3 moves upward and switch is closed a floodgate, under tripping spring 13 and reverse electromagnetic force acting in conjunction, make the switching tube separating brake by top guide bar 1 and insulator 9 when moving downward by top guide bar 1, contact spring 10 and insulator 9.
