Background technology
Along with development of city, electricity need load is more and more concentrated, and this has just proposed requirement for the large-scale substation entering area, down town of 110kV and above voltage class.Because area, down town land used is nervous, so generally adopt the construction method of indoor substation.
Indoor substation has land used to be economized, and plant maintenance is easy, moistureproof windproof characteristics such as good, but also exist building once to build completion by final layout, and construction investment is big, and it is high that equipment quality requires, and the installation place is little, problems such as scrap build difficulty.
Particularly, in the past, because the space is limited in the indoor substation building, large-scale construction equipment such as crane can't use, and therefore when building designs, was necessary for to install to reserve suspension centre and passage.
For example, main transformer is an equipment the heaviest in the substation, should place it in the position of one deck, and the adjacent street of face, is convenient to transportation; Clear headroom in the transformer chamber should be not less than the twice of main transformer height; The one side in face street adopts open type, treats that main transformer installs the back and seals with movable cement plate or steel plate door, is convenient to carry out overhauling reform work after the operation.
In addition; The GIS of 110kV and above voltage class (gas insulated metal enclosed swit chgear) facility location is when indoor; Should by equipment the weight requirement of heavy unit a single-beam loop wheel machine is installed, the effective range of operation of the suspension hook of this loop wheel machine should be than each big one unit length about GIS installation site, each 1m of front and back; Lifting rope height that the maximum sling height of suspension hook must not require less than GIS equipment producer (when lifting rope is chevron pointing, lambdoid angle must not greater than 60 °) and the vacant height sum of 30cm.The turnover gate of GIS equipment should be by 2 times of GIS device height, and width designs by the size that plant width adds 2m; Handling dead zone between crane and the indoor loop wheel machine should dwindle as far as possible, prevents to cause that disc insulator damages owing to will haul GIS.
As when the outdoor primary equipment of indoor installation 110kV and above voltage class, because the porcelain insulator of this kind equipment is longer, size is bigger, can not break transportation, therefore must above the installation site, reserve hoisting ring, answers one one mutually.
Because the high-tension apparatus volume is big, Heavy Weight, most of parts are super-long and super-wide spare, generally can't transport required floor by elevator, so need reservation equipment handling platform on each floor of building.Door on the platform should and highly respectively increase 1m by packing measurement width the wideest in this building and the highest equipment to be considered, considered equipment is at indoor turn radius when mobile simultaneously; Should reserve equipment removal path around the building, guarantee that full size vehicle and slingcart can directly reach under the hoisting platform.
