Abstract
The invention discloses a replacing bracket for a 220kV tubular bus ground knife in an electric fence. The replacing bracket comprises a girder, a plurality of telescopic support rods for supporting the girder, bases fixedly arranged at the lower end of the support rods and connecting devices for connecting the girder with each-phase tubular bus; the support rods are adjusted to be stretched; the girder upwards and downwards moves along with the support rods; and the connecting devices are used for hanging each-phase tubular bus to vertically move together and to be separated from each-phase porcelain bottle, so that the replacement of each-phase tubular bus ground knife can be operated. According to the replacing bracket disclosed by the invention, the replacement of the three-phase tubular bus ground knives can be realized by one-time operation and the problems of low efficiency, high risk and difficulty in operation caused by respective positioning for each phase required by using a crane can be avoided.
Description
Technical field
The tooling device using while the present invention relates to a kind of electrical network maintenance, the support using while being electrical network 220 kV tubular bus grounding knife switch replacing specifically.
Background technology
Electric equipment all has certain useful life, exceedes its health status after the prescribed time-limit running time and declines, and the defect fault of appearance increases thereupon, brings risk to power grid security.Therefore must renovate to long operational time, equipment that failure rate is high.According to the plan of 220kV ramp station comprehensive automation improvement project, former domestic 220kV tube type bus ground cutter need be replaced by import Areva Ta product, and because of two kinds of ground knife structure differences, cutter side supports porcelain vase to change in the lump over the ground.
In tubular bus structure, toughness is poor compared with conventional steel reinforced aluminium conductor, and bending amplitude has strict restriction.After porcelain vase dismounting, due to Action of Gravity Field, tubular bus can drop, and must have and support or pulling force effect maintenance tubular bus level, otherwise tubular bus even ruptures permanent deformation.
Passing 110kV tubular bus grounding knife switch replacing once used hoist lifting hook to draw above tubular bus, because arm beat amplitude is large, can not finely tune, and terrestrial operation personnel was because of distance, are difficult to accurate control, adjustment difficulty was installed larger.
220 kV tubular bus ground knife in electric fence is in tubular bus central authorities, crane is difficult to pendulum position, and tubular bus height is up to 9 meters, because of adjacent tubular bus belt electricity, arm stretches restricted, and it is extremely difficult changing use crane away from road near the cutter medially of charged tubular bus.High pressure place is relatively narrow, can only enter a crane, and every replacing one all needs again to put position mutually, and spended time is longer.
In sum, crane method, operating risk is high, constructional difficulties, time span is wide, easily causes between tubular bus beat fracture, adjacent tubular bus the accidents such as short circuit.Therefore, for reducing risk, increase work efficiency, must study a kind of new instrument and replace traditional crane.
Summary of the invention
Technical problem to be solved by this invention is: a kind of electrical network 220 kV tubular bus grounding knife switch replacing support is provided, reach improve electrical network 220 kV tubular bus grounding knife switch replacing operating efficiency, low-risk object is fallen.
Solving the problems of the technologies described above taked technical scheme is: a kind of electrical network 220 kV tubular bus grounding knife switch replacing support, comprise girder, support girder several telescopic support bars, be fixed on the base of support bar lower end and connect the jockey of girder and each phase tubular bus.
Adjusting support bar is flexible, girder with its upwards, move downward, jockey drives each phase tubular bus upper and lower together, separates with each porcelain vase that originally withstood on each phase tubular bus below, can operate the replacing of each phase tubular bus grounding knife switch simultaneously.
Described jockey comprise be arranged on girder below auxiliary beam, be divided into auxiliary beam two ends for capturing the anchor ear of tubular bus by transiting rod, connecting plate successively.
Wing nut that described support bar can move up and down along screw rod while comprising the screw rod that is vertically fixed on base, rotation, be enclosed within on screw rod and be supported on the steel pipe on wing nut.
The described each base unification that is fixed on support bar lower end is supported on a grade beam.
Described post upper is all fixed with for holding up girder and can preventing the positioner that girder is dislocated, described positioner comprises a base plate, is relatively arranged on the locating piece of plate upper surface, two described locating piece upper center are to having two holes, interspersed a positioning rod in hole, described girder is placed between two locating pieces.
On described each base, be all fixed with the boss being connected with base for strengthening support bar.
Prior art relatively, the present invention has following beneficial effect:
Install after support, operation support bar stretches out, and jack-up girder drives the balance rising simultaneously of each phase tubular bus, with the corresponding porcelain vase separation of being located at each phase tubular bus below, can operate the replacing of three-phase ground cutter simultaneously, and efficiency is high; Meanwhile, closely operate support bar flexible, contribute to accurate control, safety.
