Abstract
The utility model relates to a gear positioning device for transformer tapping switch contacts. The gear positioning device comprises an insulator, a switch seat, static contacts circumferentially arranged in the insulator, a main shaft penetrating through the switch seat, fixed contacts arranged on the main shaft through a supporting member, and mobile contacts corresponding to the static contacts. The gear positioning device is characterized in that a positioning disc is arranged on the switch seat, positioning pits or bosses corresponding to the gear positions of the contacts are arranged on the periphery of the positioning disc, and an axial resilient sliding sleeve is sleeved on the main shaft above the positioning disc. The lower end of the axial resilient sliding sleeve is provided with positioning pits or bosses, which are corresponding to the positioning pits or bosses on the positioning disc. Installation and debugging accuracy is greatly raised, the use performance of the switch is improved, and the operation stability is enhanced. Testing the performance of the semi-finished switch and transformer is convenient. Moreover, the gear positioning device is reasonable in structure. The positioning disc and the axial sliding sleeve are made of nonmetals, which improves the safety use performance of the switch.
Description
Technical field
The utility model relates to a kind of contact gear positioner that is used for the sub-connecting switch of transformer body part, is the further improvement to existing product.
Background technology
Existing single-phase drum-shaped shunting switch mainly is made of insulating cylinder, switch base, main shaft and dynamic/static contact, and the gear conversion is to locate by the contact matching of dynamic and static contact in the structure usually.For strengthening the accuracy and the stability of location, had and on switch base, set up contact gear positioner, this positioner is made of ring flange that positioning pit is set and the keeper of installing hoodle, keeper and main shaft connect firmly, when operating mechanism drives the main shaft rotation, the drive keeper leaves a positioning pit and slides on ring flange, the initial moment of operation has feel greatly, when reaching another positioning pit, keeper reaches another hole of corresponding next gear automatically under hoodle pressure, have than the rival and feel, be that switch reaches another service position from a service position, when the operating mechanism operation of transformer outside, can feel comparatively obvious, improve the installation and debugging precision to a certain extent.But, increase day by day along with transformer capacity, the electric current of switch is also increasing, switch moment increases thereupon, the staring torque of this contact gear positioner is big and have the advantage of certain feel to be weakened relatively, and the metal dust that produces in the switch gearshift procedure of elasticity pearl and ring flange also can bring certain hidden danger to transformer in addition.Also there are similar drawback in heterogeneous drum switch, switch cylinder and tubular switch on the market.
Summary of the invention
Technical problem to be solved of the present utility model is to avoid the deficiency of above-mentioned prior art existence and the sub-connecting switch of transformer contact gear that a kind of structure is provided with rationally, serviceability is more excellent positioner is provided.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include insulator and switch base, the edge circumferentially is installed on fixed contact in the insulator, install main shaft in the switch base, main shaft is installed by supporter and is decided contact, moving contact and fixed contact phase configuration, it is characterized in that on switch base, installing positioning disk, positioning disk is provided with positioning pit or positioning boss along circumferential corresponding contact gear, suit one axial elasticity sliding sleeve on the main shaft of (or below) above the positioning disk, axial elasticity sliding sleeve lower end is provided with locating convex block or location pit, with the positioning pit or the positioning boss phase configuration of positioning disk.
Press such scheme, described positioning pit is along the upper surface that circumferentially is installed in positioning disk, and the positioning pit pitted surface is arc surface or taper seat.
Press such scheme, described axial elasticity sliding sleeve comprises the axial sliding sleeve that is sleeved on the main shaft, upper end at axial sliding sleeve is installed on the compression spring, in the lower end of axial sliding sleeve locating convex block is set, and the locating convex block correspondence of axial elasticity sliding sleeve lower end is set to circular arc projection or circular cone projection.
Press such scheme, offer axial slide on the described axial sliding sleeve, axial slide and the alignment pin phase configuration of crossing main shaft.
Press such scheme, described positioning disk and axial sliding sleeve are made by nylon or engineering plastics.
The beneficial effects of the utility model are: it is strong that 1, axial elasticity sliding sleeve elasticity is set, the initial moment of switch gear shift operation has feel greatly, also has very rival's sense when arriving another gear, can obviously feel when on the operating mechanism of transformer outside, operating like this, especially when installing, operating mechanism feels the accuracy of positioned internal from external energy, increase substantially the installation and debugging precision, optimized the serviceability of switch, strengthen the stability of operation, also be convenient to the semi-finished product Performance Detection of switch and transformer.2, structure is provided with rationally, adopts nonmetal making positioning disk and axial sliding sleeve, can avoid the metal removal powder to pollute transformer, has improved the safe application performance of switch.3, the utility model can be used for cydariform, tubular and tubular switch, comprises single-phase, heterogeneous shunting switch, especially is adapted to operating mechanism and does not become whole split type switch in Switch main body.
