Description
Technical field
The utility model relates to a kind of oil immersed type transformer binding post tool specially for attaching and detaching.
Background technology
For the oil immersed type transformer series products equipment of power system 110kV and above electric pressure, the nut crimping is used in the sealing of secondary side binding post.The crimping nut is subjected to running environment and equipment transformer self vibrates, influence of temperature variation, and it is loosening easily to be in operation, and causes seepage oil.When handling herein seepage, need clamp nut, in this process, screw rod is very easy to work day and night, and causes inner winding leads short circuit, causes protection malfunction, Secondary Winding scaling loss, measures serious consequences such as inaccurate, has had a strong impact on the safe and stable operation of electrical network.
The utility model content
The technical problems to be solved in the utility model provides a kind of oil immersed type transformer binding post tool specially for attaching and detaching, and it has characteristics such as simple in structure, easy to use.After having used the binding post tool specially for attaching and detaching, by screwing depression bar head jacking concentric shafts (guide rod) top, play fixation, concentric shafts (guide rod) is no longer worked day and night when fastening.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Comprise box spanner, it also comprises the guide rod hold down gag, the guide rod hold down gag comprises the hollow skeleton that has internal thread hole, pinch grip is fixedly arranged at hollow skeleton top, screwing depression bar is connected with hollow skeleton internal thread, screw the depression bar top and be provided with rotating handles, be provided with the skeleton connecting hole with the sleeve concentric at the sleeve top, hollow skeleton bottom cunning is assigned in the skeleton connecting hole of sleeve.
The utility model further improves and is:
Box spanner is connected to form by sleeve and ratchet spanner.
Screw the depression bar bottom and be " one " word sphenocephaly.
The beneficial effect that adopts technique scheme to produce is:
After having used the binding post tool specially for attaching and detaching, by screwing depression bar head jacking concentric shafts (guide rod) top, play fixation, concentric shafts (guide rod) is no longer worked day and night when fastening.Stop the generation that transformer secondary side concentric shafts (guide rod) is worked day and night effectively, and can fasteningly also can become flexible screw by the control pin of ratchet spanner, very convenient.Save lot of manpower and material resources, guaranteed construction speed and promoted the stable operation of system.It has simple in structure, easy to use, characteristics such as be easy to carry.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, hollow skeleton; 2, pinch grip; 3, screw depression bar; 4, rotating handles; 5, sleeve; 6, ratchet spanner.
The specific embodiment
By embodiment shown in Figure 1 as can be known, comprise box spanner, it also comprises the guide rod hold down gag, the guide rod hold down gag comprises the hollow skeleton 1 that has internal thread hole, pinch grip 2 is fixedly arranged at hollow skeleton 1 top, screws depression bar 3 and is connected with hollow skeleton 1 internal thread, screws depression bar 3 tops and is provided with rotating handles 4, be provided with the skeleton connecting hole with sleeve 5 concentrics at sleeve 5 tops, hollow skeleton 1 bottom cunning is assigned in the skeleton connecting hole of sleeve 5.
Box spanner is connected to form by sleeve 5 and ratchet spanner 6.
Screw depression bar 3 bottoms and be " one " word sphenocephaly.
Using method:
Concrete use is in proper order: earlier hollow skeleton screw end is screwed in fixedly concentric shafts (guide rod), twist and screw depression bar, by jackscrew head jacking concentric shafts (guide rod) top, play fixation, concentric shafts (guide rod) is no longer worked day and night when fastening.After locating, box spanner is enclosed within on the crimping nut, uses the ratchet spanner just can clamp nut.And can fasteningly also can become flexible screw by the control pin of ratchet spanner, very convenient.
Range of application: oil immersed type transformer binding post tool specially for attaching and detaching is applicable to that all have the oil-immersed type power equipment of binding post structure, can be generalized to the industrial system that all use oil-immersed type power equipment.
