Abstract
The utility model relates to a permanent-magnetic operating driving mechanism, which is a driving mechanism for switch circuit devices of breakers, etc. An existing operating mechanism has the disadvantages of complicated structure, lower operational reliability, difficult maintenance and large energy consumption for operating, such as a spring type structure, an electromagnetic structure, etc. The utility model adopts a structure combining a permanent magnet and an electromagnetic device; the structure is very simple; the utility model has only one moving member; the failure rate is low; the operational reliability is high; the energy consumption for operating is low; thereby, the utility model is especially suitable for a vacuum circuit breaker body; the utility model is also suitable for assembling into various new high-voltage circuit breakers, automatic reclosing devices, etc. which can run without maintenance. The utility model can brings the convenience and high reliability for units using switching devices.
Description
Permanent-magnet manipulating mechanism described in the utility model is the driving mechanism that device for switching equipment such as a kind of circuit breaker is used.
At present, the driving mechanism that device for switching equipment is used has spring mechanism, electromagnetic type mechanism etc., the spring mechanism complexity, movable member more or less a hundred, the source of trouble is many, reliability is low, bring a lot of difficulties to care and maintenance, the required operation energy consumption of electromagnetic mechanism is very big, is difficult to be applied to occasions such as on-pole switch, and these two kinds of mechanisms all need machinery to take off locker, easily initiating failure.Therefore, design a kind of simple in structurely, high reliability is easy to safeguard that the novel operating mechanism that energy consumption is low is very necessary.
In view of above-mentioned existing in prior technology problem, the purpose of this utility model be the design a kind of simple in structure, operation energy consumption is low, the novel permanent magnetic operating mechanism of reliable operation, the utility model adopts two operation principles, and reliability increases greatly, to the also reduction greatly of requirement of transmission mechanism.
Permanent-magnet manipulating mechanism described in the utility model is characterized in that being made up of upper end cover, static iron core, moving iron core, drive link, permanent magnet, coil and bottom end cover; Upper and lower end cap is installed on the upper and lower side of static iron core respectively, moving iron core is positioned at the inner chamber of static iron core and can moves up and down, the periphery of moving iron core is surrounded with permanent magnet, drive link is being fixed in the center, and drive link stretches out from end cap center up and down respectively, and and end cap between be provided with guide pin bushing, one end of drive link links to each other with transmission mechanism, be provided with the coil around moving iron core in the static iron core, coil links to each other with power supply, is provided with pad in the middle of moving iron core and the bottom end cover.Permanent-magnet manipulating mechanism described in the utility model is characterized in that coil can be set to unicoil, also can be set to twin coil.Permanent-magnet manipulating mechanism described in the utility model is characterized in that the dynamic and static iron core of end cap is the ferromagnetism ferromagnetic material up and down, and pad and drive link are non-strong magnetic material.
Permanent-magnet manipulating mechanism described in the utility model has fundamentally solved the existing complex structure of operating mechanism in the past, the shortcoming that operation energy consumption is big and mechanism is not easy to safeguard, provide a kind of reliable operation for device for switching equipment effectively, novel permanent magnetic operating mechanism simple in structure, that operation energy consumption is low.This product movable member have only one, the source of trouble is few, reliable operation, operation energy consumption is very low; This product adopts two formula operation principles, and its functional reliability is more increased, and in addition, this product requires very low to transmission mechanism, and the machinery that need not easy initiating failure takes off, lock, buckle device.
Accompanying drawing two width of cloth Fig. 1 of the present utility model: permanent-magnet manipulating mechanism Fig. 2 of single coil structure: among the permanent-magnet manipulating mechanism figure of two coil configuration: 1, upper end cover 2, fixed core 3, moving iron core 4, drive link 5, permanent magnet
6, coil 7, bottom end cover 8, guide pin bushing 9, pad
The specific embodiment of permanent-magnet manipulating mechanism described in the utility model is as shown in drawings: its structure is made up of upper end cover 1, static iron core 2, moving iron core 3, drive link 4, permanent magnet 5, coil 6 and bottom end cover 7; Upper and lower end cap 1,7 is installed on the upper and lower end of static iron core 2 respectively, drive link 4 is fixed in the moving iron core 3, the periphery of moving iron core 3 is surrounded with permanent magnet 5, moving iron core 3 is positioned at the inner chamber of static iron core 2, drive link 4 stretches out from upper and lower end cap 1,7 centers respectively, and and being provided with guide pin bushing 8 between end cap, an end of drive link 4 links to each other with transmission mechanism; Be provided with the coil 6 around moving iron core 3 in the static iron core 2, coil 6 is fixed in recess on the static iron core 2, and coil 6 links to each other with power supply, moving iron core 3 and the bottom end cover 7 middle pads 9 that are provided with.Coil 6 can be unicoil or two coil configuration, and upper and lower end cap 1,7 and dynamic and static iron core 2,3 are the ferromagnetism ferromagnetic material, and pad 9 and drive link 4 are non-strong magnetic material.
When the utility model is done closed procedure, coil 6 energising, moving iron core 3 moves upward under the force action in magnetic field that hot-wire coil produces and permanent magnet 5 magnetic fields.When arriving make position, coil blackout, moving iron core 3 is inhaled in make position under permanent magnet 5 the action of a magnetic fields.When doing breaking operation, to single coil structure, logical reverse current in the coil 6 is to two coil configuration, logical reverse current in another coil, the magnetic field that coil 6 is produced is opposite with permanent magnet 5 magnetic directions, and permanent-magnetic field weakens, and suction reduces, to activate iron core 3 under the effect of transmission mechanism medi-spring, get back to open position, a duty cycle is finished in coil 6 outages.
