                產品結構

                Product Structure

                YBM-40.5預裝式變電站是將35KV高壓電氣、35/10KV、6KV、0.4KV電力變壓器,10KV、6KV、0.4KV開關柜,直流電池屏、繼電保護屏,按預定方案成套組合在一起的高低壓變電裝置,有整體式和分體式兩種結構,分體式變壓器置于室外,并通過一定的防護間隔形成變壓器安裝區,變壓器至兩開關柜之間通過架空母線或電纜線連接。


                YBM-40.5預裝式變電站箱體一般采用優質鋼板經表面防腐和噴涂處理后組成或采用彩鋼復合板、鋁合金板、不銹鋼板,中間施以隔熱材料。還可選用玻璃纖維增強特種水泥板的非金屬殼體。電力變壓器的散熱采用自然通風和強迫通風相結合,高、中壓室、低壓室可采用空調和防凝露裝置來控溫控濕。各功能室及通道都裝有照明燈,便于操作和觀察。


                YBM-40.5預裝式變電站35KV高壓側可選用XGN-40.5箱式固定開關柜,或KYN-40.5型鎧裝移開式開關柜或ABB公司GIS-ZX140. 5KV型開關柜。


                YBM-40.5 prefabricated substation is a high and low voltage substation device to combine 35KV high-voltage electrical equipment, 35/10KV、6KV power transformers, 10KV, 6KV and 0.4KV switch cabinets, DC battery screen and relay protection screen together in accordance with the scheduled program. There are two structures of integral type and split type. The split type of transformer is installed outside of the room and forms the installation area for transformer through some protection intervals. The transformer and the two switch cabinets are connected by overhead buses or cables.


                YBM-40.5 prefabricated substation box generally adopts high quality steel plate composed after surface antisepsis and spraying treatment, or uses colored steel composite board, aluminum board, stainless steel plate, with heat insulating materials put in the middle. In addition, non-metal shell of glass fiber reinforced special type of cement board can also be selected. Heat dissipation of power transformer adopts the combination of natural ventilation and forced ventilation, and high and medium pressure chamber and low pressure room can respectively adopt air conditioning and anti-condensation device to control temperature and moisture. Each function room and passage are equipped with illuminative lights, which is convenient for operation and observation.


                Respecting the 35KV high voltage side of YBM-40.5 prefabricated substation, XGN-40.5 box-type fixed switch cabinet or KYN-40.5 armored moving style switch cabinet or the GIS-ZX140.5KV switch cabinet of ABB Company can be selected.
