Description
Technical field
The present invention relates to whole group of a kind of 66kV isolating switch and change special hanger.
Background technology
At present, the method of known replacing 66kV isolating switch has two kinds, a kind of is to use crane to carry out whole group of lifting, but requisite space is larger, is only suitable for operation in the large and newly-built transformer station of power failure range, also having a kind of is to adopt the artificial pole of erectting to carry out the replacing of single-phase isolating switch, but will play four bracing wires on the top of pole, pole is fixed, also is limited to power failure range, need mobile pole during operation simultaneously, operating efficiency is low, waste time and energy, and increased again the dangerous spot in work.At the actual 66kV of transformer station isolating switch, changing in operation, is substantially all the single loop power failure operation, faces mutually interval all charged, no matter adopts which kind of method all to have great potential safety hazard.
Summary of the invention
For the unfavorable safety that overcomes existing two kinds of construction methods and the drawback of inefficiency, the invention provides whole group of a kind of 66kV isolating switch and change special hanger, this suspender installation, simple to operate, coefficient of safety is high, only need four-player can in two hours, complete more changing jobs of one group of 66kV isolating switch, high efficiency.
The technical solution adopted for the present invention to solve the technical problems is:
Whole group of replacing special hanger of 66kV isolating switch, include support, arm, controller, electric reducer, assembly pulley and hook, arm is rack-mount, assembly pulley is arranged on arm, one end of assembly pulley is connected with hook, the other end of assembly pulley is connected with electric reducer, and electric reducer is connected with controller by cable.
The junction of described support and arm is provided with steering rod.
Described assembly pulley is comprised of fixed pulley, fixed block, movable pulley and steel wire rope, and an end of steel wire rope is fixed on arm, and the other end of steel wire rope is connected with electric reducer after walking around successively movable pulley, fixed block and fixed pulley.
Be provided with the switch bracket fixture on described support, described switch bracket fixture is comprised of L50 angle steel and 100mm channel-section steel.Advantage and effect that the present invention has are:
The present invention adopts two 100mm channel-section steels to make the switch bracket fixture, use diameter two and half coating steel pipes to make support, adopt 3 cun coating steel pipes of diameter to make arm, use threephase motor to drive the dynamical system of worm-gear type reductor as suspender, actuating is partly that positive and negative the transferring of controlling motor with reversible magnetic starter reaches the operation that disconnecting link hoists and lands, lifting rope adopts the steel wire rope of diameter 8mm, adopt movable pulley to alleviate steel wire rope stressed, improved reliability, and the suspender overall package is very convenient, built-up time is about 10 minutes.High efficiency, saving personnel and manpower, reduce power failure range, only needs this loop to have a power failure and can meet operating condition, improved power supply reliability.Can guarantee at power failure range less (only when space before have a power failure), charged position nearer, can't use in the situation of crane, use this special hanger to complete whole group of work of changing of 66kV isolating switch, and assembling, easy to operate, save manpower and time, increase work efficiency, can also guarantee operation field safety.
