概述 Outline

本智能型一體化變電站是華電電氣公司推出的國產化美式箱變。該產品作為電纜化配電網中重要的供電單元，集高壓控制、保護、變電、以及配電設備于一體的成套預裝產品，廣泛應用于城鄉配電網之中。該產品將高壓負荷開關、高壓熔斷器置于變壓器油中，具有與變壓器身共箱或分箱兩種結構形式。油箱采用全密封結構，配有油溫表、油位表、壓力表、壓力釋放閥、放油閥等元件監測變壓器運行狀況。該產品分為環網型、終端型及電源型供電方式。為了使此種產品更適合于我國電網的實際要求，榮爾公司又推出了插拔型干式熔斷器，熔絲的熔斷不影響變壓器油的性能。根據低壓饋出要求的復雜程度，此產品分為標準型、加強型和綜合型三種外殼形式，使用戶和設計單位在選型時，做到更靈活、更經濟。

This intelligent integrated transformer substation is a nationalized type American box substation developed by HUADIAN ELECTRIC Company. As an important power supply unit in the cable distribution network, it is an in tegrated prefabricated product of high voltage control, protection, power transformation and power distribution, whichis widely used in the urban and rural distribution network.The high voltage load switch and high voltage fuse are put into the transformer oil, so this product has two structure forms of one box and divided box with the transformer body. The oil box is of full-sealed structure with oil temperature indicator, oil level gauge, pressure gauge, pressure relief valve and oil drain valve to monitor the operation condition of the transformer. This kind of products has three types of power supply modes ring network type, terminal type and power type. In order to make the product meet the actual demands of the power grid in China better, Ronger Company promotes plug-pull dry type fuse and the fusing of the fuse wire has no effect to the performance of transformer oil. According to the complicated degree of low voltage outgoing demands, this product has three types of enclosure - standard type, reinforced type and integrated type, as a result, the clients and design agents have more choices.
