Description
Technical field
The present invention relates to high-voltage board to power peripheral equipment field, relate to a kind of isolating switch overhaul working platform and manufacture craft thereof specifically.
Background technology
10kV high-voltage board due to run the time limit for a long time, the reason such as ageing equipment and frequent operation, unavoidably switching winding will be caused to burn, and then need the problem of emergency opening.
At the 10kV high-tension switch cabinet of transformer station's erection, the reasons such as the time limit is permanent owing to running, ageing equipment, often occur that separating brake process burns switching winding, cannot the urgent defect of normal distant place separating brake.If now switch internal or outside line break down again, protection act but cannot separating brake, and switch will be caused to explode, and bypass the immediate leadership and jump 10kV mother and main transformer switch, the power grid accident of 10kV bus loss of pressure, therefore must take the measure of emergency opening.Have a power failure the switching winding more renewed, and transfer switch to inspecting state as early as possible, distant place control loop breaks, can only pass through scene manual brake separating on the spot.On-load Manual local separating brake on the spot, electric power safety code does not allow, and has certain danger, if now switch cubicle fault causes inseparable or short circuit, closing vacuum will be caused to steep explosion, cause huge loss of life or personal injury and power grid accident.Had a power failure by whole section of bus if each, then replacing switching winding that fault high-voltage board is had a power failure, suppose that each bus stops power transmission operation and needs 3 hours, on average relate to 15 10kV circuits, the average power transmission load of every bar circuit is 0.433 ten thousand kW at every turn.If there is above-mentioned situation, serious impact will be caused on residential electricity consumption, maintainer therefore must be arranged to overhaul to scene.
As shown in Figure 1, this figure is current high-tension electricity erecting structure, is to be formed by bolt erection by some U-type groove steel plates 6, and unsettled in the middle of platform, the steel plate of upper lateral is liftoff at least 3 meters, even reaches the height of more than 10 meters.The daily repair and maintenance work must carrying out the parts such as junction block, dynamic/static contact, fingertip conducting rod, insulator, grounding switch, base assembling on the narrow framework channel-section steel of isolating switch of maintenance teams and groups, task is quite heavy, service position is narrow, staff's foothold of standing is less, lacking is the position of hanging safety belt, cannot exert a force, dismounting inconvenience.When high-tension apparatus breaks down, maintainer is by standing on the steel plate that set up, overhauling high-tension apparatus, although there is safety line in maintainer system, in moving process, its foothold is just walked up and down between steel plate, be very easy to drop, threat to life safety.Therefore, maintainer is when to this isolating switch debugging and maintenance, both inconvenient, has again certain danger.
Summary of the invention
For the deficiency in above-mentioned technology, the invention provides a kind of isolating switch overhaul working platform and manufacture craft thereof, this overhaul working platform is layed on framework channel-section steel, adopts right angle hook bolt to fix, and anti-sliding stop, turns over and sticks up.

Further, the hook recess gauge lattice in the middle part of described corrosion resistant plate are the elongated hole of Φ 11*100mm, and hook groove is made up of the semicircle at rectangle and rectangle two ends.
Further, described spud pile is square lath, and its length is identical with maintenance sheet width.
Further, also comprise right angle hook bolt, this hook-type bolt thread place, right angle cover has wing nut.
Further, on described right angle hook bolt, also cover has meson, and this meson is placed in inside wing nut.
A manufacture craft for isolating switch overhaul working platform, is characterized in that following steps:
1), select anti-skidding resin plate, anti-skidding resin plate is made into the cuboid that specification is long 1600 mm, wide 500 mm, thick 30 mm, this rectangular flat plate is maintenance flat board;
2), by above-mentioned steps 1) in maintenance planar bottom surface follow closely two spud piles, spud pile is perpendicular to the dull and stereotyped long limit of maintenance, and two spud piles divide the broadside distance of taking leave of maintenance dull and stereotyped to be 300mm, and described spud pile specification is long 500mm, wide 50mm, thick 50mm;
3), make the dull and stereotyped mounting groove of maintenance, this mounting groove through hole, specification is Φ 11*100mm, and the rectangle is namely long is 100mm, and half circular diameter on both sides is 11mm;
4), along mounting groove groove rafter fix a reinforcement corrosion resistant plate, this reinforcement corrosion resistant plate specification is long 160mm, wide 60mm;
5), in maintenance dull and stereotyped central region, safety belt hanger rod is installed, this safety belt hanger rod height 1300mm, specification are overall diameter 65mm × thick 6mm, the stainless steel tube of top tape fixing hole, its bottom welding on one piece of square stainless steel faceplate, then is fixed on maintenance flat board by square head bolts;
6), by right angle hook bolt wing nut outward winding, take out meson, then by threaded for right angle hook bolt one end through mounting groove, be inserted in meson, finally wing nut screwed in screw thread.
The invention has the beneficial effects as follows:
1. utilize overhaul working platform of the present invention, the line service of 110kV isolating switch was reduced to 1 hour used time by double 2 hours of average used time, the defect processing work of 110kV isolating switch was reduced to 4 hours used times by double 8.4 hours of average used time.
