Abstract
The invention relates to an inspection device for a transformer on-load voltage regulation switch. The inspection device is composed of a cross bar, a hoisting assembly suspension unit, bracing frames, bottom feet, annular hoops, fixed plates, obliquely-drawing units, a pallet bracing frame and a maintaining pallet. A fixed base plate on each bottom foot is designed in a way that the fixed base plate is arc-shaped and is matched with the top of a transformer, and therefore the installing surface is relatively more suitable and stable; by arranging the obliquely-drawing units, shaking during the hoisting process is avoided, and safety of the on-load voltage regulation switch and maintenance personnel are effectively protected; by arranging the maintaining pallet, oil on the on-load voltage regulation switch which is hoisted falls into the pallet and enters the transformer, the environment is effectively protected, and the risk that during the maintaining process, components fall into the transformer is avoided; by arranging a screen mesh in the maintaining pallet, oil which flows into the transformer is clean; and the inspection device for the transformer on-load voltage regulation switch is simple in structure and convenient to use, and can hoist stably, and is provided with great practical value and popularization value.
Description
Technical field
The present invention relates to a kind of for overhauling device during on-load voltage regulating switch in transformator, specifically a kind of on-load tap-changer of transformer apparatus for examination and repair。
Background technology
Through retrieving relevant patent documentation, not yet retrieve a kind of on-load tap-changer of transformer apparatus for examination and repair identical with present configuration at present。The dynamic/static contact of inside transformer on-load voltage regulating switch, transition resistance, fastening bolt are carried out maintenance and be necessary for hanging out on-load voltage regulating switch in transformator, one is that maintainer stands on the transformer by after upper cover dismounting, transformator is carried away after tying down on-load voltage regulating switch with rope, heavier plus on-load voltage regulating switch, have to the 3rd people switch is held after overhaul, due to limited space on transformator, tap changer is very easily caused to topple the injury of damage and personnel once praise people's carelessness；Two is take crane to lift by crane, and due to limited space in transformer station, crane is difficult to arrive position resolver and lifts by crane, and uses crane costly, easily causes the damage of switch during lifting；Three is lift by crane with small-sized hoisting platform, owing to the base of small-sized hoisting platform is made relatively larger, cannot be placed on transformator and lift by crane, owing to just hanging out, the on-load voltage regulating switch of transformator there is oil, during maintenance, oil easily splashes, cause the pollution of environment, it is therefore necessary to a kind of on-load tap-changer of transformer apparatus for examination and repair of design, be actually needed to meet。
Summary of the invention
The invention aims to provide a kind of simple in construction, lifting is a kind of on-load tap-changer of transformer apparatus for examination and repair smoothly。
The present invention is technically characterized in that a kind of on-load tap-changer of transformer apparatus for examination and repair being designed to be made up of cross bar, lifting assembly suspension arrangement, bracing frame, footing, hoop, fixed disk, oblique drawing device, tray support frame, maintenance pallet on the basis that performance easy to use, safe is high, lifting assembly suspension arrangement is sleeved on cross bar, and can move axially along cross bar；Bracing frame is respectively equipped with footing, fixed disk；Oblique drawing device is connected with cross bar by bolt；Cross bar forms door frame by hoop with bracing frame；Tray support frame is arranged on bracing frame；Tray support frame is provided with maintenance pallet。
Described footing is made up of mounting base, floor, and mounting base is the plate body of an arc-shaped structure matched with transformer top, and is provided with bolt fixing hole。
Described hoop is the hoop of " U " the type version adopting double threaded screw to make。
Described oblique drawing device is made up of steel wire tow line, tension regulating part, retainer ring, is provided with tension regulating part on steel wire tow line；It is fixed with retainer ring at the two ends of steel wire tow line。
Described maintenance pallet is made up of disk body, screen cloth, oil outlet, is provided with oil outlet on disk body；In disk body, oil outlet place is provided with screen cloth；Disk body is a pyramidal structure form disk body adopting anti-rust metal material to make。
During use, take the connection of transformer top apart, with bolt, bracing frame is arranged on the top of transformator, again through hoop, cross bar is fastened on bracing frame and forms door frame, oblique drawing device is installed, steel wire tow line one end on oblique drawing device is connected with cross bar, the other end is connected with transformer top, under the effect of tension regulating part, steel wire tow line is strained, the door frame making bracing frame and cross bar composition will not swing, lifting assembly suspension arrangement has hung up hanging piece, when on-load voltage regulating switch is from after hanging out in transformator, maintenance pallet is placed on the tray support frame on bracing frame, the oil now flowed down on on-load voltage regulating switch will drop in maintenance pallet, and flow back in transformator by the screen cloth in pallet through oil outlet, the parts taken apart are prevented by maintenance process in maintenance pallet, thus avoiding on-load voltage regulating switch parts when slinging maintenance to fall into the danger of transformator。
The invention have the advantage that owing to adopting cross bar and bracing frame to assemble, consequently facilitating carry, easy for installation；Owing to the fixing back-plane design on footing becomes the arc-shaped structure form matched with transformer top, so that installed surface is more fitted, more steadily；Owing to being provided with oblique drawing device, thus avoiding rocking in lifting process, it is effectively protected the safety of on-load voltage regulating switch and maintainer；Owing to being provided with maintenance pallet, enter in transformator after in dish thus the oil on the on-load voltage regulating switch after lifting falls into, be effectively protected environment, and avoid parts when maintenance and fall into the danger of transformator；Owing to being provided with screen cloth in maintenance pallet, thus the cleaning of oil in ensure that inflow transformer；Due to simple in construction, easy to use, lifting is steady, so there being very big practical and popularizing value。
