在本期的知識大講堂中，我們將分析講解“高低壓配電”產(chǎn)品中“箱式變電站”這一系列產(chǎn)品。它的適用環(huán)境是什么，又有什么樣的電氣特性呢？讓我們走進大講堂，來了解一下“箱式變電站”吧~

產(chǎn)品簡介：

箱式變電站，又叫預(yù)裝式變電所或預(yù)裝式變電站。設(shè)計標(biāo)準(zhǔn)依據(jù)GB17467-2010 《高壓、低壓預(yù)裝式變電站》。是一種由高壓開關(guān)設(shè)備、配電變壓器和低壓配電裝置，按一定接線方案排成一體的工廠預(yù)制戶內(nèi)、戶外緊湊式配電設(shè)備，即將變壓器降壓、低壓配電等功能有機地組合在一起，安裝在一個防潮、防銹、防塵、防鼠、防火、防盜、隔熱、全封閉、可移動的鋼結(jié)構(gòu)箱，特別適用于城網(wǎng)建設(shè)與改造，是繼土建變電站之后崛起的一種嶄新的變電站。也稱歐式箱變。箱式變電站適用于礦山、工廠企業(yè)、油氣田和風(fēng)力發(fā)電站、住宅小區(qū)、城市公用變、繁華鬧市、施工電源等它替代了原有的土建配電房、配電站、成為新型的成套變配電裝置。

主要性能與特點：

1. 箱體外殼組成：變電站的箱體是由底座、外殼、頂蓋三部分構(gòu)成。底座一般用槽鋼、角鋼、扁鋼、鋼板等，組焊或用螺栓連接固定成形；為滿足通風(fēng)、散熱和進出線的需要、還應(yīng)在相應(yīng)的位置開出條形孔和大小適度的圓形孔。箱體外殼可以采用碳鋼、水泥、復(fù)合板等制作。

2. 外觀：箱變的表面處里：箱變表面處理在北方大多采用傳統(tǒng)的噴漆、烤漆、噴塑等方法進行處理；在中國南方經(jīng)濟發(fā)達(dá)地區(qū)，除采用上述方法外，還在水泥板結(jié)構(gòu)的殼體外貼上彩色瓷磚，或貼面等方法進行表面處理，特別是置于住宅小區(qū)的箱變外觀，與當(dāng)?shù)亟ㄖ锏娘L(fēng)格更加協(xié)調(diào)、統(tǒng)一。

Brief introduction :

Box type transformer substation, also called the pre-installed substation or prefabricated substation. It is designed according to the standard GB17467-2010 “high pressure, low pressure pre-installed substation”. It is a by the high voltage switchgear, distribution transformer and low voltage power distribution device, according to a certain wire connection scheme, factory prefabricated indoor and outdoor compact type distribution equipment. That is, the substation makes step-down transformer, low-voltage power distribution and other functional devices organically combined together and put all in a moisture-proof, rust proof, dust proof, fire prevention, anti-theft, heat insulation and fully enclosed movable steel structure box, especially used in urban network construction and reconstruction. The box type substation, also known as European box, has become a new set of power transformation and distribution device and is widely used in mines, factories and enterprises, oil and gas fields and wind power station, residential quarters, public facilities in city, the bustling downtown, construction power supply which replaces the former civil power distribution room and power distribution station.

Main performance and features :

1. Box shell composition:Transformer substation box is composed of three parts: base, shell and cover.Base with channel steel, angle steel, flat steel, steel plate etc., group welding or bolt connection fixation and forming; to meet the ventilation, heat dissipation and inlet and outlet wires need, should open strip holes and moderate size of circular holes in the corresponding positions. Box shell can be made of carbon steel, cement, composite plate and etc..

2. Appearance: Surface treatment: Most areas of North China, the traditional paint spraying, baking finish, plastic-sprayed processing are used; in the economic developed areas of South China, in addition to the above-mentioned methods, also color tiles or veneers pasted on cement plate structure are used, especially the box placed in the residential quarters, which makes the appreance of the box more coordinated and unified with local style buildings.
