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 sliding block and a screw guiding rod are suited at the leading-out end of the moving iron core guiding rod, an upper sliding block is connected with the screw guiding rod in a screwed connection way, a baffle block is arranged corresponding to the upper sliding block, two guiding tracks are arranged on the supporting plate which matches with the lower sliding block, a shifting rod is equipped at the tail part of the lower sliding block through a pin, 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 upper and lower slide block that agrees with mutually, utilize sliding block along guide wheel movement jack-up top shoe, thereby drive moving iron core guide rod, 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 at moving iron core guide rod exit, sliding block, the screw thread guide pin bushing, the top shoe that is threaded with the screw thread guide pin bushing, the block of corresponding setting with top shoe, on supporting bracket, be provided with two guide rails that are complementary with sliding block, driving lever is installed in the afterbody of sliding block by pin, at described driving lever tail end back-moving spring is installed; Described sliding block, top shoe 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.

Embodiment

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

Embodiment 1: as shown in the figure, a kind of permanent magnet mechanism mechanical type manual switching-off device, comprise permanent magnet mechanism 1 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 2 at moving iron core guide rod 7 exits, sliding block 4, screw thread guide pin bushing 8, the top shoe 5 that is threaded with screw thread guide pin bushing 8, with corresponding two hex nuts 6 using as block that are provided with of top shoe 5, top shoe 5 just is fixed on by two hex nuts 6 and screw thread guide pin bushing 8 and moves on the iron core guide rod like this; Be provided with two guide rails 3 that are complementary with sliding block 4 on supporting bracket, driving lever 9 is installed in the afterbody of sliding block 4 by pin, and driving lever 9 also is provided with a fulcrum and rotates to make things convenient for driving lever 9 on guide rail, at described driving lever tail end back-moving spring 10 is installed; Described sliding block 4, top shoe 5 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 sliding block 4 by driving lever 9 and slide along guide rail, thus jack-up top shoe 5, two hex nuts 6 that top shoe 5 jack-up are used as block, thereby the moving iron core guide rod 7 of drive moves upward, and the moving iron core of moving iron core guide rod 7 tractions moves upward, and makes the air gap of iron core adhesive face generation greater than 0.5mm, the suction-combining force is fallen sharply, separating brake under the effect of tripping spring.
