Abstract
The invention discloses a general-purpose substation totally enclosed switchgear busbar canister cross ladder. The general-purpose substation totally enclosed switchgear busbar canister cross ladder comprises a collapsible cross bridge portion and a retractable cross ladder portion. The collapsible cross bridge portion comprises four collapsible cross bridges, a metal support riser and four collapsible metal support transverse plates, wherein the adjacent two collapsible cross bridges and the collapsible metal support transverse plates are connected through a unidirectional rotating hinge respectively, and metal support rods are arranged between the collapsible metal cross bridges and the collapsible metal support transverse plates and respectively connected to the collapsible metal cross bridges and the collapsible metal support plates. The retractable cross ladder portion comprises cross ladder single sections and rotating communication valves, wherein the adjacent two cross ladder single sections are connected together through the rotating communicating valve and the top cross ladder single section is fixedly welded to the metal support riser. The general-purpose substation totally enclosed switchgear busbar canister cross ladder satisfies all arrangement forms of a busbar canister, so that an operation maintainer can easily pass through the busbar canisters directly rather than passing back and forth from both ends of the busbar canister, and accordingly the operating time of operation maintenance is reduced.
Description
Technical field:
The present invention relates to a kind of bus bar canister across ladder device, particularly relate to a kind of universal transformer station fully closed combined electric unit bus bar canister across ladder, belong to electric power apparatus examination and safeguard aid, be applicable to transformer station's fully closed combined electric unit repair and maintenance and use.
Background technology:
Fully closed combined electric unit (being called for short GIS) adopts SF6 gas as dielectric, and all component of high voltage electrical apparatus (bus, circuit breaker, isolating switch, current transformer, voltage transformer, lightning arrester, earthing isolator etc.) are sealed in the high voltage distribution installation in grounded metal cylinder.Fully closed combined electric unit GIS compares with traditional open type high-voltage power distribution equipment has following obvious advantage: compact conformation, and the occupation of land space of whole device greatly reduces; Not by the impact of external environment, operational reliability is high, and the time between overhauls(TBO) is long.Along with the development of transformer station's technology, fully closed combined electric unit has now been widely used in transformer station.Fully closed combined electric unit bus bar canister is the important component part of GIS, because bus is often longer, and centre not breaking, can only detour from bus bar canister two ends so want to be cross over opposite side from bus bar canister side in operation, tour process, compare and waste time and energy.
In actual repair and maintenance work, power transformation operation maintenance personnel needs are often maked an inspection tour fully closed combined electric unit, safeguard, are operated, and inevitably will arrive bus bar canister both sides in real time and observe equipment or operate.Through investigation, find that the disposing way of current transformer station GIS bus bar canister has three kinds of modes, two kinds of height, see Fig. 6 (Fig. 6 is the side sectional view of three kinds of bus bar canister disposing ways).In order to meet the needs of the various disposing ways of bus bar canister, needing to design a kind of height-adjustable, the contractile universal insulation of bridge across ladder, the needs of all disposing ways of bus bar canister can be met.
Summary of the invention:
Technical problem to be solved by this invention is: the universal transformer station fully closed combined electric unit bus bar canister providing a kind of structure simple, reasonable in design, across ladder, can meet the needs of all disposing ways of bus bar canister.
The technical scheme that the present invention takes for technical solution problem is:
A kind of universal transformer station fully closed combined electric unit bus bar canister is across ladder, comprise collapsible bridge part and scalable across terraced part, described collapsible overbridge part divides the collapsible bridge comprising upper end, the metallic support riser on both sides and the collapsible metallic support transverse slat of lower end, described collapsible bridge and collapsible metallic support transverse slat are four pieces, between adjacent two pieces all by single direction rotation gemel connection together, metallic support rod is provided with in the middle of collapsible bridge and collapsible metallic support transverse slat, described metallic support rod is linked together with adjacent collapsible bridge and collapsible metal profile respectively by connection hinge, describedly scalablely to comprise across terraced single-unit and adjacent across the rotational communication valve between terraced single-unit across ladder part, adjacent two are linked together by rotational communication valve across terraced single-unit, the metallic support riser across terraced single-unit and collapsible bridge part both sides is topmost fixed and welded together.
State between metallic support riser and collapsible bridge, collapsible metallic support transverse slat and linked together by movable adapter.
Described collapsible bridge and all have high density epoxy resin insulation material to process across terraced single-unit.
Structure of the present invention is simple, reasonable in design, by collapsible bridge part and scalable folding or stretching across ladder part, can meet the needs of all disposing way height of bus bar canister and width.
Use time-division following several situation:
1. double-bus is discharged (see Fig. 6 part A) side by side with layer:
Use front expansion: side the present invention being moved to totally-enclosed bus bar canister, by the strength of metallic support rod, collapsible bridge part is stretched to both sides, makes it launch completely; Tilt across ladder, make one end bay ladder leg be cross over bus bar canister opposite side.
Use rear folding: tilt across ladder, make its two legs be cross over bus bar canister the same side, by the strength of metallic support rod, upwards push away collapsible metallic support transverse slat, make it completely folding.
2. double-bus discharges (see Fig. 6 part B) up and down side by side:
Use front expansion: side the present invention being moved to totally-enclosed bus bar canister, by the strength of metallic support rod, collapsible bridge part is stretched to both sides, makes it launch completely; Tilt across ladder, make one end bay ladder leg be cross over bus bar canister opposite side.Then, height as required, connects adjacent two by rotational communication valve and makes it lengthen afterwards in steady status across terraced single-unit.
Use rear folding: tilt across ladder, make its two legs be cross over bus bar canister the same side.Disassembled lengthened below across terraced single-unit by rotational communication valve; Inwardly push away the collapsible metallic support transverse slat of bridge plate bottom, inwardly push away collapsible bridge both sides simultaneously, make it completely folding.
3. single busbar connection (see Fig. 6 C part):
Occupation mode with situation 1..
Launch before use of the present invention to make an inspection tour in operation maintenance personnel or carry out in preoperative preparation.Convert mode and the position of expansion according to bus bar canister disposing way in operating process.
The present invention can make operation maintenance personnel directly pass through bus bar canister very easily, need not detour back and forth and flog a dead horse, thus decrease the operating time of operation maintenance, reduce working strength, provide the reliability of supply line from bus bar canister two ends.
The present invention is that universal transformer station fully closed combined electric unit bus bar canister is across ladder, bridge part and all can adjusting according to length with highly across ladder part, height-adjustable, width are scalable, meet the pose pattern that bus bar canister is all, applied widely, be easy to promotion and implementation.
