Abstract

The utility model discloses a permanent-magnet mechanism mechanical type manual switching off device, which comprises a permanent-magnet mechanism casing. A moving iron core and a switching in loop are arranged in the permanent-magnet mechanism casing, a moving iron core guiding rod is equipped at the end of the moving iron core, a supporting plate, a lower screw sliding block, an upper screw sliding block and a thrust bearing are orderly suited at the leading-out end of the moving iron core guiding rod, a baffle block is arranged on the moving iron core guiding rod being corresponding to the thrust bearing, a locking clip is suited on the screw sliding block, a shifting lever threaded sleeve is welded on the locking clip, a shifting lever is connected with the shifting lever threaded sleeve, and a returning spring is equipped at the tail end of the shifting lever; the lower screw sliding block matches the upper screw sliding block. The utility model has the advantages that the device switching off force is small, the structure is simple, the operation is easy, the applicability is wide and the operation is reliable.

Description

A kind of permanent magnet mechanism mechanical type manual switching-off device

Technical field

The utility model relates to a kind of switching-off device, relates in particular to a kind of permanent magnet mechanism mechanical type manual switching-off device that high-low pressure circuit breaker, contactor are used in the electric power system.

Background technology

The permanent-magnet manipulating mechanism used of the high and low pressure switch of Chu Xianing is simple in structure with it in recent years, parts are few, the reliability advantages of higher successfully is applied in the electric power system, but which kind of permanent magnet mechanism all must possess urgent manual brake separating, when control system has a power failure or breaks down can not electronic separating brake the time, just need be with the manual brake separating powder operation device separating brake of meeting an urgent need, traditional permanent magnet mechanism mechanical type manual switching-off device: as forms such as crank mechanism, screw thread liftings, complex structure, manual brake separating is all more than tens kilograms, and the separating brake instrument takes up room very big.

The utility model content

The utility model is to overcome the defective that prior art exists, purpose is to provide a kind of permanent magnet mechanism mechanical type manual switching-off device, this device is by being provided with a pair of following spiral pieces, the last spiral pieces of agreeing with mutually, utilize driving lever to stir the spiral pieces rotation, driving moving iron core guide rod moves upward, realized the purpose of separating brake dexterously, this device separating brake power is little, simple in structure, be convenient to operation, solved the problem of existence of the prior art.

The utility model is to achieve the above object by the following technical programs: a kind of permanent magnet mechanism mechanical type manual switching-off device, comprise a permanent magnet mechanism housing, in the permanent magnet mechanism housing, be provided with moving iron core and closing coil, in moving core ends moving iron core guide rod is installed, be set with supporting bracket successively at moving iron core guide rod exit, following spiral pieces, last spiral pieces, thrust bearing, corresponding thrust bearing place is provided with block on moving iron core guide rod, be sleeved on the tight locking button on the spiral pieces, on tight locking button, be welded with the driving lever swivel nut, driving lever is threaded with the driving lever swivel nut, at described driving lever tail end back-moving spring is installed; Described following spiral pieces, last spiral pieces agree with mutually.

Described link stopper is two hex nuts.

The beneficial effects of the utility model: this device separating brake power is little, simple in structure, be convenient to operation, applied widely, reliable operation.

Description of drawings

Fig. 1 is the structural representation of the permanent magnet mechanism mechanical type manual switching-off device among the utility model embodiment 1;

Fig. 2 is the structural representation of the last spiral pieces of the permanent magnet mechanism mechanical type manual switching-off device among the utility model embodiment 1;

Fig. 3 is the structural representation that the upper and lower spiral pieces of the permanent magnet mechanism mechanical type manual switching-off device among the utility model embodiment 1 agrees with;

Fig. 4 be the following spiral pieces among Fig. 3 A to structural representation;

Among the figure: 1-moves the iron core guide rod; The 2-tight locking button; The last spiral pieces of 3-; Spiral pieces under the 4-; The 5-supporting bracket; The 6-permanent magnet mechanism; The 7-hex nut; The 8-thrust bearing; 9-driving lever swivel nut; The 10-driving lever; The 11-back-moving spring.

Embodiment

The utility model is further elaborated by embodiment below in conjunction with accompanying drawing:

Embodiment 1: as Fig. 1,2,3, shown in 4, a kind of permanent magnet mechanism mechanical type manual switching-off device, comprise permanent magnet mechanism 6 housings, in the permanent magnet mechanism housing, be provided with moving iron core and closing coil, in moving core ends moving iron core guide rod is installed, be set with supporting bracket 5 successively at moving iron core guide rod 1 exit, following spiral pieces 4, last spiral pieces 3, thrust bearing 8, corresponding thrust bearing 8 places are provided with two hex nuts 7 and make block usefulness on moving iron core guide rod 1, be sleeved on the tight locking button 2 on the spiral pieces 3, on tight locking button 2, be welded with driving lever swivel nut 9, driving lever 10 is threaded with driving lever swivel nut 9, at described driving lever tail end back-moving spring 11 is installed; Described following spiral pieces 4, last spiral pieces 3 agree with mutually.

When control system has a power failure or breaks down can not electronic separating brake the time, with the manual brake separating powder operation device separating brake of meeting an urgent need, stir driving lever, drive upward spiral pieces 3 rotations by driving lever 10, two hex nuts 7 by thrust bearing 8 jack-up are used as baffle plate move upward thereby drive moving iron core guide rod 1, the moving iron core of moving iron core guide rod 1 traction moves upward, make the air gap of iron core adhesive face generation, the suction-combining force is fallen sharply, separating brake under the effect of tripping spring greater than 0.5mm.

Claims

1, a kind of permanent magnet mechanism mechanical type manual switching-off device, comprise a permanent magnet mechanism housing, in the permanent magnet mechanism housing, be provided with moving iron core and closing coil, in moving core ends moving iron core guide rod is installed, it is characterized in that: be set with supporting bracket (5) successively at moving iron core guide rod (1) exit, following spiral pieces (4), last spiral pieces (3), thrust bearing (8), go up corresponding thrust bearing (8) at moving iron core guide rod (1) and locate to be provided with block, be sleeved on the tight locking button (2) on the spiral pieces (3), on tight locking button (2), be welded with driving lever swivel nut (9), driving lever (10) is threaded with driving lever swivel nut (9), at described driving lever tail end back-moving spring (11) is installed; Described following spiral pieces (4), last spiral pieces (3) agree with mutually.
