Description
Technical field
The utility model relates to technical field of electric power transmission, specifically relates to a kind of for the universal insulator bottle-holding rack of lightweight during charged for replacement 330kV tension double-string bunch of insulator.
Background technology
At present, when electric transmission line hot-line changes 330kV tension double-string bunch of insulator, the bottle-holding rack type used is many, weight is large, transport, installation difficulty.One of electric power enterprise production and operation target is exactly reduce the interruption duration of power equipment, improves power supply reliability and the economic benefit of company.At present, in company 330kV transmission line, the strain tower of nearly 95% is had to adopt twin insulator sub-connection mode, the existing whole string of live-line replacing strain duplex mainly adopts plain edition and reinforced bottle-holding rack, because the standby multiple supporting bottle-holding rack of teams and groups' need respectively overhauls in the difference province Jian Xiu company of line insulator string sheet number (22 ~ 24) and insulator string length (3.42 ~ 3.72m), and traditional bottle-holding rack quality large (30 ~ 40 Kg), in addition the existing tools for live working complex structure used, has made this work operations difficulty large; In addition, when line span and wire tension less time, insulator string can form comparatively the Nature stretched wire and bend, constituent parts use plain edition and reinforced bottle-holding rack be all level design, cannot be in place, this makes the live line working on 330kV strain insulator twin insulator strings very difficult at all.Mainly there is the deficiency of following several respects:
1, versatility is not possessed.The strain insulator kind of transmission line use is many inside the province,
Have plain edition porcelain insulator, anti-pollution type insulator, three umbrella insulators, composite insulator etc., insulator model is many, kind is many, and in order to can normally carry out the work, the insulator of each model only
Can use the bottle-holding rack that matches, not only infusion of financial resources is large, and manage, transport, use very inconvenient.
2, the larger insulator string of flexibility cannot be changed.Existing bottle-holding rack substantially all uses pipe
Type insulating material and metal material is supporting assembles, bottle-holding rack integrated straight type designs, nothing
The insulator string that flexibility in the less shelves of wire tension such as method replacing terminal tower is larger.
3, weight is large.Existing bottle-holding rack weight is generally at tens kilograms, and transport is inconvenience all very, because weight is very large, installs and is difficult to put in place, there is certain security risk.
For above problem, develop a kind of lightweight, universal bottle-holding rack, for charged for replacement 330kV strain tower strain insulator-string duplex bunch of insulator.
Summary of the invention
The technical problems to be solved in the utility model is the deficiency existed for prior art, provides a kind of lightweight, universal bottle-holding rack, for the universal insulator bottle-holding rack of lightweight of charged for replacement 330kV strain tower strain insulator-string duplex bunch of insulator.
A kind of lightweight of the utility model universal insulator bottle-holding rack is achieved by following technical proposals: the universal insulator string bottle-holding rack of a kind of lightweight comprises closed fixture, turns to connector, epoxy resin board, balancing pole, described closed fixture two ends are connected with epoxy resin board upper end is vertical by turning to connector, and described epoxy resin board lower end is by turning to connector and balancing pole level connection joint.
A kind of lightweight of the utility model universal insulator string bottle-holding rack has following beneficial effect compared with prior art: the universal insulator string bottle-holding rack of the utility model lightweight is rectangular frame type, during use, closed fixture is arranged on the steel cap place at insulator string side of wire the 3rd insulator place, and easily operate during the installation of the utility model closed fixture, the installation span of bottle-holding rack is little, only has the length of three insulators, not by the impact of insulator string flexibility.With the utility model bottle-holding rack with the use of coaster be arranged on insulator string side of wire connecting plate bent plate card, lifting rope tail end is through fastening on the lifting rope baffle plate of bottle-holding rack lower end balancing pole after the pulley of the pulley on electric power pylon cross-arm and coaster, and lifting rope head end hangs down to ground through after the hand being arranged on column foot.After insulator string throws off connecting plate, ground handling operator slowly decontrols lifting rope, and insulator string will slowly decline in naturally drooping state.The single present situation of method when a kind of lightweight of the utility model universal insulator bottle-holding rack will change charged for replacement or interruption maintenance 330kV tension double-string bunch of insulator in Qinghai Electric Power Corporation's system, and the problem such as when can solve charged or interruption maintenance 330kV tension double-string bunch of insulator, bottle-holding rack weight used is excessive, the scope of application is limited, transportation and storage is difficult.Reach the intensity alleviating staff, increase work efficiency, the object reduced costs.
A kind of bottle-holding rack that is lightweight, charged for replacement 330kV tension double-string bunch of insulator that the scope of application is wide, easy and simple to handle of the utility model can substitute the function of traditional plain edition bottle-holding rack and reinforced bottle-holding rack charged for replacement 330kV strain insulator duplex bunch of insulator completely, meets the requirement that live line working and interruption maintenance can use.
The utility model bottle-holding rack has the following advantages:
(1) Work tool transport is convenient to.The utility model lightweight bottle-holding rack can be contained in any motor vehicles, and it is very convenient to transport.
(2) manpower transport is convenient to.The most tower erection of lines is in high mountain high hill, and in service work, vehicle is often difficult to arrive tower position, and this just needs to go down the hill to transport Work tool by manpower, and the utility model lightweight bottle-holding rack quality only has 7Kg, transports quite light.
(3) the utility model portability, universal bottle-holding rack be not by the restriction of insulator string flexibility.The utility model portability, universal bottle-holding rack only need cross-over connection three insulators due to middle installation, and therefore not by the restriction of insulator string flexibility, no matter level insulation substring, or the larger insulator string of flexibility all completes replacing task.
(4) the utility model portability, universal bottle-holding rack have good general feature, do not limit by insulation sub-pieces number.As long as the utility model lightweight bottle-holding rack one pair can change different sheet number and length insulator string.
(5) the utility model portability, universal bottle-holding rack can be convenient for changing different tonnage insulator string.What 330kV strain insulator tonnage was conventional has 160KN and 210KN two kinds, because parameter is different, insulator steel cap size is also inconsistent, when using the utility model lightweight bottle-holding rack to change different tonnage insulator, only need change supporting closed fixture, and the different each grass-roots unit of tonnage closed fixture all there is ready-made configuration.
(6) Work tool protection against the tide is conducive to.The utility model lightweight bottle-holding rack because of length short, volume is little, can be loaded directly into vehicle case inner, can not by the impact of special weather.
(7) processing safety can be improved.The utility model portability, the main stressed member of versatility bottle supporting have employed closed fixture, be provided with reliable locking device, and be positioned at side of wire yoke plate place because of hoisting rope suspension centre, insulator string can not occur with tower material to rub and collide in dropping process, can ensure the safe and reliable of operation in the overall process used.
