Abstract

The utility model discloses a clamping fixture for exchanging a paired gang insulator with an opening current. The clamping fixture for exchanging paired gang insulator with an opening current takes the method of a stringing pull plate to exchange a straight-line paired gang insulator on the supertension line of 500 kv, mainly including a tightener, the stringing pull plate, a joint, and the clamping fixture of a yoke plate. Tensile forces are tightened by the tightener, which enables wire tension bore by a string of insulators in paired insulator strings to divert on the stringing pull plate and the clamping fixture of a yoke plate, and the string of insulators are changed into a relaxed state, which obtains the goal of exchange. The clamping fixture of the utility model can be a split mounting type. The utility model has the advantages of small size, light weight, less operators, and convenient hot-line work. The clamping fixture for exchanging a paired gang insulator with an opening current makes up the insufficiencies of general public known devices for exchanging straight-line paired gang insulators with opening currents.

Description

The present invention relates to a kind of on 500 kilovolts of supertension lines charged for replacement straight line duplex bunch of insulator jig.
The device volume of general known charged for replacement straight line duplex bunch of insulator is bigger, and heavy, the machinery and the auxiliary facility that need during live line working are more, needs the operating personnel of usefulness also more, brings many inconvenience to live line working.
Task of the present invention is, a kind of 500 kilovolts of supertension line charged for replacement straight line duplex bunch of insulator jigs that are applicable to are provided, and it has in light weight, and volume is little, and is easy to operate, needs with advantages such as operating personnel are few.
Adopting charged for replacement duplex bunch of insulator of the present invention is with stringing arm-tie method.Charged for replacement duplex bunch of insulator jig mainly is made up of wire grip, stringing arm-tie, joint and yoke plate jig.Tighten up tension force by wire grip, the wire tension that the insulator string in the twin insulator strings is born is transferred on stringing arm-tie and the yoke plate jig, so that this insulator string becomes relaxed state, reaches the purpose of replacing.
The invention will be described in further detail below with reference to accompanying drawing.
Fig. 1 is a structure assembling schematic diagram of the present invention.
Fig. 2 is the front view of yoke plate jig.
Fig. 3 is the sectional drawing that Fig. 2 upper edge I-the I line is cut open.
Fig. 4 is the sectional drawing that Fig. 2 upper edge II-the II line is cut open.
Fig. 5 is the horizontal view of yoke plate jig.
With reference to Fig. 1, charged for replacement duplex bunch of insulator jig is by wire grip (1), cross-arm carrier base (2), and joint (3), stringing arm-tie (4), yoke plate jig parts such as (8) are formed.Stringing arm-tie (4) is connect with bearing pin (7) and screw (6) by joint (3) with yoke plate jig (8), and stringing arm-tie (4) is connect with screw (6) by joint (3) with wire grip (1).Wire grip (1) is fixed on jig of the present invention on the tower head cross-arm (13) by cross-arm carrier base (2).Yoke plate jig (8) is made up of two of front and back.
With reference to Fig. 2~5, yoke plate jig (8) respectively has a circular hole on two hangers (14 and 18) that stretch out, be respectively (15 and 19), there is a semicircle gap (20) at yoke plate jig (8) middle part, circular hole (16) locates to have on the plate body triangular flanges (23), circular hole (21) locates to have on the plate body triangular flanges (22), circular hole (16 and 19) centre-to-centre spacing is 210 millimeters, circular hole (19 and 21) centre-to-centre spacing is 230 millimeters, the arc radius of gap (20) is 55 millimeters, it is 75 millimeters that gap (20) is located plate body (17) wide, and gap (20) end is 36 millimeters to hanger (18) base portion distance, and yoke plate jig (8) plate body length is 724 millimeters.Each one that the front and back of yoke plate jig (8) are two is measure-alike, is that two corresponding flanges (22,23) overlap after falling face processing.
When adopting the present invention to carry out charged for replacement straight line duplex bunch of insulator on 500 kilovolts of supertension lines, its working method is as follows:
The wire grip (1) of the charged for replacement straight line duplex bunch of insulator jig that assembled is fixed on the tower head cross-arm (13) by cross-arm carrier base (2), by the equipotential electrician yoke plate jig (8) is fixed on the lead gold utensil on the thick stick yoke plate (10) with bolt (9,11).Afterwards, the earth potential electrician tightens up wire grip (1) on the tower, upwards promotes by the afterbody of stringing arm-tie (4) with yoke plate jig (8), at this moment, the load transfer that the insulator string that is replaced (12) is born is to stringing arm-tie (4), and this insulator string is in relaxed state.Equipotential electrician breaks away from insulator string (12) and lead, and the earth potential electrician has held the carriage (5) of insulator string (12) by the tackle pulley pulling on the tower, and insulator string (12) is pulled to horizontal level under the cross-arm (13), changes the insulator operation.
Link plate clamping tool of the present invention (8) is by aluminum alloy materials, such as LC4,L C9,L D5Make, perhaps made by titanium alloy material, a whole set of charged for replacement duplex insulator clamp apparatus weight is little, easy to use, assemble type, be convenient to 500 kilovolts of workings on live ultrahigh tension power lines, need the operating personnel of usefulness also less, remedied the deficiency of general known electrified replacing linear duplex bunch of insulator device.
