Abstract
The utility model relates to a clamping device for the live replacement of two insulators at one end of a 500kV power line. A hinged hanging plate (3) is hinged with a twin plate (2). A row of hanging holes (6) are formed on the bottom surface of the twin plate (2). A dedicated twin plate clamping device (1) is a shaped plate. Connection holes (7) are respectively formed at both ends of the dedicated twin plate clamping device, wherein the connection hole at one end thereof is connected with the hanging hole of the twin plate via bolts and the other end thereof is detachably connected with a double-thread rod plate (8). The double-screw rod plate is hinged to the right end of a double-thread rod (5). The left end of the double-thread rod is connected with the intermediate hole of the twin plate (2). The clamping device has the advantages of time-saving, labor saving, safe and reliable operation process.
Description
Technical field:
The utility model belongs to the extra high voltage network live line working, and charged for replacement 500kV strain insulator four the 33rd, 34 of strings are the special-purpose yoke plate jig of two insulators in termination apparatus structure technical field.
Technical background: the transmission line long-time running is in the field, the insulator of circuit is because of the effect of bearing power-frequency voltage, atmospheric over-voltage, switching overvoltage and mechanical load for a long time and the influence of external environment, null value, low value can appear in various degree or by lightning stroke flashover, reduce the insulation level of circuit, influenced safety, the stable operation of transmission line.
For improving the insulation level of transmission line, need null value and flashover insulator are changed.The 33rd, 34 (just the termination is two) insulators of charged for replacement 500kV circuit tension resistant four-serial are difficult problems always how convenient and strength-savingly, the at present domestic operational method of still not having the successful experience of the 33rd, the 34th insulator of charged for replacement 500kV circuit tension resistant four-serial, unformed special-purpose yoke plate instrument, not having maturation.
Summary of the invention:
The utility model is combined by special-purpose yoke plate jig, two yoke plates, hinged link plate, insulator monolithic card, double lead, its jig apparatus structure is: hinged link plate and two yoke plates adopt and are hinged, below two yoke plates, offer row's hanging hole, special-purpose yoke plate jig is a stripe board, two ends at special-purpose yoke plate jig offer connecting hole respectively, this connecting hole of one end adopts nut to be connected with the hanging hole of two yoke plates, the other end and double lead yoke plate flexibly connect, and the double lead yoke plate is hinged with the double lead right-hand member again; The double lead left end is hung with the interstitial hole of two yoke plates and is connected.
The beneficial effects of the utility model are, with special-purpose yoke plate jig and insulator monolithic card, double lead combination, the carrying out of success the charged for replacement of 500kV strain insulator four the 33rd of string, 34 insulators.Operation process is time saving and energy saving, has novelty, fail safe and reliability.
Further set forth the utility model content below in conjunction with drawings and the specific embodiments.
Description of drawings:
Fig. 1 is the utility model structural representation.
