Abstract
The invention provides a GIS (gas insulated switchgear) mounting method in a 220kv transformer substation room and relates to the field of transformer substations. The GIS mounting method includes steps of (1) transporting a GIS into the transformer substation room by a hydraulic trailer; (2) unloading the GIS to the ground from the hydraulic trailer; (3) hanging a chain block on a hanging bracket, lifting a bus by the chain block and mounting the bus. The combined appliance mounting method in the 220kv transformer substation room is simple, practical, safe and firm, cost is saved in the integral process, and post maintenance investment and labor cost are reduced.
Description
Technical field
The present invention relates to transformer station field, be specifically related to the installation method of the indoor GIS combination electric appliance of 220kv transformer station.
Background technology
GIS combination electric appliance is the abbreviation of gas-insulating and fully-enclosed combined electrical apparatus, is made up of circuit breaker, isolating switch, earthed switch, instrument transformer, lightning arrester, bus, connector and outlet terminal etc.The indoor GIS combination electric appliance of 220kv transformer station belongs to large electric equipment, and factory building domestic demand is equipped with driving lifting machine, needs large scale hoisting machinery just can finish the work in installation process.In present transformer station, GIS combination electric appliance has been in maturing, universalness, the GIS combination electric appliance Maintenance free of normal operation, driving in factory building is in idle state relatively, must safeguard every year according to large scale hoisting machinery, detect, the factors such as a large amount of expense and workload need be produced, therefore a lot of transformer station has just cancelled driving lifting machinery equipment when designing, this has just brought a lot of inconvenience to installation.Such as, due to objective condition restriction, when transformer station's area is less, under nothing driving design conditions, crane also cannot enter transformer station indoor.
Summary of the invention
The object of this invention is to provide the installation method of the indoor GIS combination electric appliance of a kind of 220kv transformer station, the method is simple and practical, safety is firm, to whole engineering economy cost, decrease the maintenance fund in later stage and the expenditure of labour.
Object of the present invention adopts following technical scheme to realize.
The installation method of the indoor GIS combination electric appliance of 220kv transformer station, comprises the steps:
(1) adopt hydraulic trailer that GIS combination electric appliance is transported to transformer station indoor;
(2) GIS combination electric appliance is unloaded to ground from hydraulic trailer;
(3) on suspension bracket, hang zipper calabash, to sling bus with zipper calabash, bus is installed.
4 5t hydraulic trailer carrying 20tGIS combined electrical apparatuses are adopted in step (1).
The concrete grammar of step (2) is: be positioned over by sleeper below GIS combination electric appliance, extracts hydraulic trailer out, then turns with machinery and withstand on below GIS combination electric appliance, lay down sleeper, GIS combination electric appliance is positioned over ground.
The described crossbeam that comprises forms with the A font supporting leg be connected to below crossbeam.
Described A font supporting leg is made up of two steel pipe legs and buttress brace, the welding of described two steel pipe leg one end, and the two ends of buttress brace are connected with two steel pipe legs respectively; Described two steel pipe leg welds are connected with described crossbeam.
Universal wheel is equipped with in the lower end of described steel pipe leg.
Do not design the difficulty of the GIS combination electric appliance indoor location of driving lifting machinery equipment: when the mobile heavy weight electric equipment of interior length distance, do not have other dynamic power machines to replace using; When indoor lifting is installed, lifting machine cannot enter indoor hoisting.Indoor in the 220kv transformer station not designing driving lifting machinery equipment, adopt the inventive method that GIS combination electric appliance is installed, indoor transporting have employed 4 5t hydraulic trailer carryings, lifting during installation adopts suspension bracket, simple and practical, safety is firm, to whole engineering economy cost, decrease the maintenance fund in later stage and the expenditure of labour.
Accompanying drawing explanation
The front view of Fig. 1 suspension bracket, wherein 1-crossbeam, 2-A font supporting leg.
The end view of Fig. 2 suspension bracket, wherein 1-crossbeam, 3-steel pipe leg, 4-buttress brace.
Embodiment
embodiment 1
1. GIS combination electric appliance before assembly, first GIS combination electric appliance is transported to 220kv outside transformer substation.Adopt the GIS combination electric appliance of 4 5t hydraulic trailer carrying 20t, GIS combination electric appliance is transported to 220kv transformer station indoor design position.With hydraulic trailer transport, equipment overhead only has 10 centimetres, can not fall, tilt, and very steady time mobile, fail safe is high.
2. the sleeper of 4 10 cm thicks is positioned over below GIS combination electric appliance, extracts hydraulic trailer out, then turn with machinery and withstand on below GIS combination electric appliance, lay down sleeper, GIS combination electric appliance is positioned over ground.
3. on suspension bracket, hang zipper calabash, to sling bus with zipper calabash, bus is installed.The A font supporting leg 2 that suspension bracket comprises crossbeam 1 and is connected to below crossbeam.A font supporting leg 1 is made up of two steel pipe legs 3 and buttress brace 4, and the upper end of described two steel pipe legs is weldingly connected, and the two ends of buttress brace are connected with two steel pipe legs respectively.Two steel pipe leg welds are connected with described crossbeam by channel-section steel.Because the setting height(from bottom) of bus is 2.5m, so select the steel pipe leg of long 3.5m, ￠ 50,12 channel-section steels that crossbeam selects 2.5m long.Suspension bracket must can carry the weight of 300kg.Can load onto universal wheel steel pipe leg lower end (relative with crossbeam connecting place), to move accurate counterpart when installing, the zipper calabash landing of crossbeam hanging 1 1t uses.So just can accomplish that multi-azimuth tridimensional adjusts.
Miscellaneous part in GIS combination electric appliance conventionally according to.
