Abstract
The invention relates to a transformer binding post guide rod connector threading die hitching method and a special hitching device and belongs to the technical field of power supply repair and maintenance. According to the technical scheme, the special hitching device comprises a sleeve (2), a threading die hitching device (6) and a rotating wrench (1). The sleeve is of a hollow steel cylindrical structure (3), the rotating wrench is welded to the side surface of the upper portion of the sleeve so as to be convenient to rotate, an observation groove (4) is arranged on the middle lower portion of the sleeve, the observation groove is arranged longitudinally and communicated with a hollow portion in the sleeve, a fixed ring (5) is arranged at the lower end of the sleeve, an annular positioning groove (7) is arranged on the threading die hitching device and matched with the fixed ring at the lower end of the sleeve, the fixed ring is inserted in the positioning groove, and the fixed ring and the positioning groove are fixedly connected together through bolts. The transformer binding post guide rod connector threading die hitching method and the special hitching device have the advantages of being simple to operate and convenient to use, prolonging service life of a guide rod, eliminating accident threads, avoiding tedious and complicated replacement of the guide rod, being suitable for field service, shortening operation time and power-off time, and improving working efficiency.
Description
Technical field
The present invention relates to a kind of transformer connection post rod coupling screw die hitch method and special-purpose hitch device, belong to power supply repair and maintenance technical field.
Background technology
During the transformer operation, the binding post rod coupling is overheated, and the phenomenon that causes the guide rod screw-socket to damage generally takes place.When this just requires not damage fully, must change guide rod, because this number transformer is huge, not have accident potential if do not change, background technology can only be changed guide rod, necessary power failure operation, and the time is long, and it is loaded down with trivial details to work, and reduces power supply reliability.When guide rod also damages fully, do not use, can eliminate the work that this hidden danger can avoid changing guide rod again.
Summary of the invention
The object of the invention provides a kind of transformer connection post rod coupling screw die hitch method and special-purpose hitch device, when guide rod also damages fully, do not use, can eliminate safe hidden trouble, can avoid changing the work of guide rod again, do not need long-time power failure, solve the problems referred to above that background technology exists.
Technical scheme of the present invention is:
The special-purpose hitch device of a kind of transformer connection post rod coupling comprises sleeve pipe, screw die hitch device and rotary spanner, and sleeve pipe is the hollow steel column structure, and the sleeve pipe upper side is welded with rotary spanner, is convenient to rotation; The sleeve pipe middle and lower part is provided with the observation groove, observing groove vertically arranges, hollow penetrating with in the sleeve pipe, the convenient transformer guide rod situation of observing, the lower end of sleeve pipe is provided with retainer plate, screw die hitch device is provided with annular positioning groove, the retainer plate of annular positioning groove and sleeve pipe lower end is complementary, and retainer plate inserts locating slot, and is bolted to connection together, bolt connects, and conveniently changes and repair screw die hitch device at any time.
Described rotary spanner is two handles, and symmetry is fixed on the sidewall of upper cartridge respectively.
Described observation groove is two, is symmetricly set on the sidewall of sleeve.
A kind of transformer connection post rod coupling screw die hitch method adopts above-mentioned special-purpose hitch device to carry out, when the maintenance repair of carrying out transformer is safeguarded, find that transformer connection post rod coupling screw-socket produces burr, have a power failure, transformer connection post rod coupling nut is unclamped, take off connection cable; The screw die hitch device of sleeve lower end is installed on the rod coupling, observes the rod coupling situation of sleeve the inside by observing groove; With the hands the rotary spanner on rotational sleeve top is twisted several times clockwise, the rod coupling screw-socket is produced burr twist, and prolongs the service life of guide rod; Cable is put back on the rod coupling,, fastening nut is finished the work.
Good effect of the present invention: be installed on the transformer guide rod, rotate rotary spanner and can make screw die hitch device and guide rod friction, easily burr is twisted, simple to operate, easy to use, prolong guide rod service life, both eliminate accident potential, avoided the replacing guide rod of very complicated again, be fit to on-the-spot the use, shorten activity duration and power off time, improved operating efficiency.
