Description
Technical field
The invention belongs to the bracing or strutting arrangement of maintenance power transformer load tap changer internal mechanism.
Background technology
In electric power system, get in touch with electrical network with on load tap changer, but the steady load center voltage improves the electric equipment operation condition and improves the supply power voltage quality.On load tap changer is to guarantee under the situation of not cutting off load current, by the regulator of a tap-change operation to another parted hair.At present, on load tap changer obtains using very widely in electric power system.Because shunting switch needs constantly action and cuts off load current, acts frequently.And shunting switch causes failure rate higher owing to reasons such as manufacturing process, installation, service conditionss, accounts for the large percentage of transformer body fault.Traditional shunting switch mechanism complexity, weight is heavier, causes service work loaded down with trivial details, adopts crane operation usually, and it is more to employ personnel.Simultaneously, because the substation complexity, the vacant lot area is little and equipment is more, indoor transformer particularly, crane usually can't be parked use, therefore causes slowing down, and causes the waste of human and material resources, financial resources.Secondly the difficult control of the strength of crane in case command improperly, might cause the damage of personnel and shunting switch.
Summary of the invention
Technical problem to be solved by this invention provides a kind of on-load tapping switch hanger, is implemented in to carry out the shunting switch maintenance on the transformer body easily, is not subjected to the influence of environment landform, and is simple to operate, shortens maintenance duration, promotes safety in production.
On-load tapping switch hanger of the present invention, it is characterized in that comprising suspension bracket top, supporting leg, pulley, suspension hook, wire grip, described suspension bracket top has a rectangular shape, pulley is installed in the center on suspension bracket top, the position, four angles on suspension bracket top is fixedly connected supporting leg respectively, the bottom of every supporting leg connects a mobilizable leg, wherein a supporting leg top fixedly mounts a pulley, middle part fixed installation wire grip, wirerope is connected with wire grip by the pulley on the suspension bracket top, the pulley on the supporting leg, suspension hook of the terminal connection of wirerope.
Described suspension bracket pushes up a kind of concrete production method: by being the framework that four steel pipes are welded into square shape, weld two steel pipes on the diagonal of framework, form cross frame, pulley is installed in the center of cross frame, weld a fixture on four jiaos of framework respectively, have bolt hole on the fixture, the top of described supporting leg links together by the fixture that bolt and suspension bracket push up on four jiaos.
After product of the present invention assembles, can be transported on the transformer body that has a power failure to be repaiied, four movable legs of supporting leg bottom are fixed on four suspension ring of shunting switch top cover by manpower, check that product is fixed after, can use.During use, at first slowly suspension hook is put down, trigger the steel wire rope that is connected in the shunting switch mechanism by the control wire grip.Before the lifting, guarantee shunting switch and transformer body screw complete removal in succession, check errorless after, can work on.Slowly operate wire grip, shunting switch is slowly sling, in the operating process, carefully check, prevent that the protruding part of switch from propping up body.Be sure not rough power and operate wire grip energetically, in order to avoid cause pulling and device damage of personnel.
The present invention utilizes the design feature (switch dome is stamped the suspension ring of four loading and unloading usefulness, can play support bracket fastened effect) of shunting switch top cover, and the flow process characteristics in conjunction with the work of maintenance shunting switch have designed this product.Use this product, can on the transformer body, carry out the shunting switch maintenance easily, be not subjected to the influence of environment landform; Break away from crane, and this suspension bracket is in light weight, simple to operate, can save human resources, shorten maintenance duration, promote safety in production.Hanger structure is simple, light, flexible, easy Fast Installation.Security performance is reliable, the indeformable (switch weight: 35-75Kg) of vertical tension 400Kg.Be applied to the suspended core of the on-load voltage regulating switch of 220KV, 110KV (MR type, ZY1A type, CV type) main transformer.

Fig. 4 is a structural representation of the present invention.
Among the figure: 1,2,3,4 fixtures, 5 pulleys, 6 cross frames, 7 frameworks, 8 bolts hole, 9 bolts, 10 bolts, 11 pulleys, 12 supporting legs, 13 wire grips, 14 movable leg 15 suspension hooks 16 suspension brackets push up 17 wireropes, 18 supporting legs
Embodiment
Fig. 1～4 are embodiment of the invention structural representation, below in conjunction with the present invention of embodiment description of drawings.
This on-load tapping switch hanger comprises assemblies such as 16,4 supporting legs in suspension bracket top and wire grip 13 and pulley.
As Fig. 1, Fig. 2, the framework on suspension bracket top 16 7 is welded by steel pipe.At first, four steel pipes are welded into square, secondly partly weld two steel pipes, form cross frame 6 at foursquare framework 7 diagonal.This cross frame 6 is a supporting part, but load-bearing 400KG (shunting switch weight is generally 35-75KG).At cross frame center welding top sheave 5, this pulley is a fixed pulley then, must weld firm and slides smooth and easy.Welding four fixtures (fixture 1～4) on four jiaos of square frames are used for connecting four supporting legs at last.The gap of cracking on the thickness of fixture and supporting leg top should coincide, and the slit after the connection should be not excessive, fixes with screw.
As Fig. 3, totally 4 of supporting legs, each supporting leg bottom connects a mobilizable leg 14 (movable shaft type connection).These legs 14 are used for respectively and four suspension hooks on load tap changer top cover top are connected and fixed (fixing by screw).Wherein a set bolt 10 is arranged at supporting leg 12 tops, is used for fixing pulley 11 is installed, and a midleg is wire grip 13 (known technology structure) fixedly, and three supporting legs 18 in addition are not provided with wire grip and pulley.Wire grip 13 is dependent manual operation for promoting the power set of shunting switch, and benefit is that control is accurate, and rising or falling speed is slower, avoids taking place because operate miss and the powerful pulling force of crane cause the serious consequence of device damage.Suspension hook 15 is used to the shunting switch of slinging, and its wirerope 17 is connected with wire grip 13 by pulley 5, pulley 13.
After this product assembles, can be transported on the transformer body that has a power failure to be repaiied, four legs 14 of supporting leg bottom are fixed on four suspension ring of shunting switch top cover by manpower, check that product is fixed after, can use.During use, at first slowly suspension hook 15 is put down, trigger the steel wire rope that is connected in the shunting switch mechanism by the control wire grip.Before the lifting, guarantee shunting switch and transformer body screw complete removal in succession, check errorless after, can work on.Slowly operate wire grip, shunting switch is slowly sling, in the operating process, carefully check, prevent that the protruding part of switch from propping up body.Be sure not rough power and operate wire grip energetically, in order to avoid cause pulling and device damage of personnel.
