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(chǎn)化美式箱變。該產(chǎn)品作為電纜化配電網(wǎng)中重要的供電單元，集高壓控制、保護(hù)、變電、以及配 電設(shè)備于一體的成套預(yù)裝產(chǎn)品，廣泛應(yīng)用于城鄉(xiāng)配電網(wǎng)之中。該產(chǎn)品將高壓負(fù)荷開關(guān)、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(jié)構(gòu)形式。油箱采用全密封結(jié)構(gòu)，配有油溫表、油位表、壓力表、壓力釋放閥、放油閥等元件監(jiān)測變壓器運(yùn)行狀況。該產(chǎn)品分為環(huán)網(wǎng)型、終端型及電 源型供電方式。為了使此種產(chǎn)品更適合于我國電網(wǎng)的實(shí)際要求，華電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(jù)低壓 饋出要求的復(fù)雜程度，此產(chǎn)品分為標(biāo)準(zhǔn)型、加強(qiáng)型和綜合型三種外殼形式，使用戶和設(shè)計單位在選型時，做到更靈活、更經(jīng)濟(jì)。

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, HUADIAN 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.
