Abstract
The utility model discloses a wrench special for a transformer on-load voltage regulation device. The wrench comprises an operating handle, a round operating head is arranged at one end of the operating handle, an oval hang hole is formed in the other end of the operating handle, grooves are formed in the inner surface of the round operating head, the grooves are two in number and vertically symmetric, and the round operating head and the operating handle are fixedly welded together. According to the wrench special for the transformer on-load voltage regulation device, before vertical splitting and connecting positions of the on-load voltage regulation device are adjusted, the grooves formed in the inner surface of the round operating head are aligned with protruded clamping points arranged on the outer side of the on-load voltage regulation device transmission pillar and then clamp the convex clamping points, so that the wrench special for the transformer on-load voltage regulation device solves the problem in the prior art that a movable wrench slips off easily and eliminates potential safety hazard on operating personnel and equipment.
Description
Technical field:
The utility model relates to a kind of transformer maintenance instrument, particularly relates to a kind of transformer on-load voltage regulating device special spanner.
Background technology:
High-power transformer generally all will carry out test operation to the transformer all parts before installing at the scene, with the overall performance of comprehensive test transformer.For the transformer with on-load voltage regulating device, on-load voltage regulating device need to carry out on-the-spot pendant-core examination test, in process of the test, needs on-load voltage regulating device is carried out to upper and lower tap position adjustment, to reach best test effect.Taking off post as cylindrical standing shape of on-load voltage regulating device, in the outside of cylinder, one convex stuck point is arranged vertically, generally with monkey wrench, be stuck in on-load voltage regulating device during current test operation and take off post above, regulate spanner card distance, regulated the test of on-load voltage regulating device tap position.But there is following shortcoming in this operation: 1., in adjustment process, monkey wrench is slippage very easily, has certain unsafe factor; 2. often slippage easily causes the take off post wearing and tearing of convex stuck point of on-load voltage regulating device, brings certain potential safety hazard.
The utility model content:
Technical problem to be solved in the utility model is: a kind of simple in structure, easy to operate, transformer on-load voltage regulating device special spanner that can not slippage is provided.
The utility model is that the technical scheme that the technical solution problem is taked is:
A kind of transformer on-load voltage regulating device special spanner, comprise operating grip, and described operating grip one end is provided with circular operating head, and the other end is provided with oval suppending hole; Described circular operating head inner surface is provided with groove.
Described circular operating head and operating grip are fixed and welded together.
Described groove is two, upper and lower symmetrical.
The utility model is before to on-load voltage regulating device, upper and lower tap position is adjusted, first by circular operating head inner surface, set groove is aimed at the take off post convex stuck point in the outside of on-load voltage regulating device, then block the convex stuck point, solve monkey wrench in prior art and held eely problem, eliminated the potential safety hazard that may bring to operating personnel and equipment.
The utility model operating grip other end is provided with oval suppending hole, while not using, is suspended on assigned address, the convenient classification, the phenomenon can not find while not there will be urgent need.
The accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
The top view that Fig. 2 is Fig. 1.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1 and Fig. 2, a kind of transformer on-load voltage regulating device special spanner, comprise operating grip 3, and operating grip 3 one ends are provided with circular operating head 1, and the other end is provided with oval suppending hole 4; Described circular operating head 1 inner surface is provided with groove 2, and groove 2 is two, and upper and lower symmetrical, circular operating head 1 and operating grip 3 are fixed and welded together.
Before to on-load voltage regulating device, upper and lower tap position is adjusted, first by circular operating head 1 inner surface, set groove 2 is aimed at the take off post convex stuck point in the outside of on-load voltage regulating devices, then blocking the convex stuck point prevents from coming off, efficiently solve monkey wrench in prior art and hold eely problem, eliminated the potential safety hazard that may bring to operating personnel and equipment.
