编辑：admin浏览次数：3342次

在本期的知识大讲堂中，我们将分析讲解“高低压配电”产品中“箱式变电站”这一系列产品。它的适用环境是什么，又有什么样的电气特性呢？让我们走进大讲堂，来了解一下“箱式变电站”吧~

产品简介：

箱式变电站，又叫预装式变电所或预装式变电站。设计标准依据GB17467-2010 《高压、低压预装式变电站》。是一种由高压开关设备、配电变压器和低压配电装置，按一定接线方案排成一体的工厂预制户内、户外紧凑式配电设备，即将变压器降压、低压配电等功能有机地组合在一起，安装在一个防潮、防锈、防尘、防鼠、防火、防盗、隔热、全封闭、可移动的钢结构箱，特别适用于城网建设与改造，是继土建变电站之后崛起的一种崭新的变电站。也称欧式箱变。箱式变电站适用于矿山、工厂企业、油气田和风力发电站、住宅小区、城市公用变、繁华闹市、施工电源等它替代了原有的土建配电房、配电站、成为新型的成套变配电装置。

主要性能与特点：

1. 箱体外壳组成：变电站的箱体是由底座、外壳、顶盖三部分构成。底座一般用槽钢、角钢、扁钢、钢板等，组焊或用螺栓连接固定成形；为满足通风、散热和进出线的需要、还应在相应的位置开出条形孔和大小适度的圆形孔。箱体外壳可以采用碳钢、水泥、复合板等制作。

2. 外观：箱变的表面处里：箱变表面处理在北方大多采用传统的喷漆、烤漆、喷塑等方法进行处理；在中国南方经济发达地区，除采用上述方法外，还在水泥板结构的壳体外贴上彩色瓷砖，或贴面等方法进行表面处理，特别是置于住宅小区的箱变外观，与当地建筑物的风格更加协调、统一。

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.
