箱式变电站(简称箱变)是一种高压开关设备、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,即将高压受电、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、可移动的钢结构箱体内,机电一体化,全封闭运行,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。根据产品结构不同及采用元器件的不同,分为欧式箱变和美式箱变两种典型风格。 箱式变电站是一种高压开关设备、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,即将高压受电、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、可移动的钢结构箱体内,机电一体化,全封闭运行,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。 另箱式变电站(简称箱变)是一种把高压开关设备配电变压器,低压开关设备,电能计量设备和无功补偿装置等按一定的接线方案组合在一个或几个箱体内的紧凑型成套配电装置。它适用于额定电压10/0.4KV三相交流系统中,作为线路和分配电能之用。适用于工厂、矿山、油田、港口、机场、城市公共建筑、居民小区、高速公路、地下设施等场所。 根据产品结构不同及采用元器件的不同,分为欧式箱变和美式箱变两种典型风格。 我国自70年代后期,从法国、德国等国引进及仿制的箱式变电站,从结构上采用高、低压开关柜,变压器组成方式,这种箱变称为欧式箱变,形象比喻为给高、低压开关柜、变压器盖了房子。 从90年代起,我国引进美国箱式变电站,在结构上将负荷开关,环网开关和熔断器结构简化放入变压器油箱浸在油中。避雷器也采用油浸式氧化锌避雷器。变压器取消油枕,油箱及散热器暴露在空气中,这种箱变称为美式箱变,形象比喻为变压器旁边挂个箱子。 从体积上看,欧式箱变由于内部安装常规开关柜及变压器,产品体积较大。美式箱变由于采用一体化安装体积较小。 从保护方面,欧式箱变高压侧采用负荷开关加限流熔断器保护。发生一相熔断器熔断时,用熔断器的撞针使负荷开关三相同时分闸,避免缺相运行,要求负荷开关具有切断转移电流能力。低压侧采用负荷开关加限流熔断器保护,美式箱变高压侧采用熔断器保护,而负荷开关只起投切转换和切断高压负荷电流的功能,容量较小。当高压侧出现一相熔丝熔断,低压侧的电压就降低,塑壳自动空气开关欠电压保护或过电流保护就会动作,低压运行不会发生。 从产品成本看,欧式箱变成本高。从产品降价空间看,美式箱变还存在较大降价空间,一方面美式箱变三相五柱铁心可改为三相三柱铁心,另一方面,美式箱变的高压部分可以改型后从变压器油箱内挪到油箱外,占用高压室空间。 箱变的型号 预装(组合、箱式)变电站 1 6(10)/0.4(0.7)kV预装(组合、箱式)变电站 2 矿用组合(箱式)变电站 3 6(10)/0.4kV预装(组合、箱式)变电站 4 35/6(10)kV组合(箱式)变电站组合式变压器 组合式变压器首先由美国有关电气公司开发。在美国叫基座式变压器,英文名称为Padmounted transformer,在国内也称美式箱变。这种变压器的熔断丝、多工位环网负荷开关、无励磁调压分接开关都作为变压器的部件装在变压器油箱内,在油箱外很容易更换熔断丝或操作负荷开关而改变变压器的运行工况。高压侧由可以带负荷插拔的肘形电缆输入电能,油箱外另装低压出线仓,仓内有空间可按要求而加装保护装置与测量仪表。所有带电部位都在箱内,无裸露带电部分。因为主要部件都在油箱内,故我们称它为组合式变压器,而不称它为箱式变电站。但组合式变压器也具有箱式变电站的功能。高压侧装有六个电缆插座,可使变压器接入环网供电系统中,与柜式环网箱或电缆分支箱组成环网供电系统。所以,组合式变压器、基座式变压器,或简称的美式箱变都是指同一种产品,主体是变压器,而不是变电站。 组合式变压器为框架结构,用型钢焊接而成,框架外蒙铝合金板,并涂专用漆层,使之具有较强的机械性能、耐侯性能、防腐蚀性能。组合式(箱式)变电站为整体结构时,箱内用钢板隔成三个相对独立的小室即高压室、变压器室和低压室。各室照明均随门的开启而自动关停。
有这种组合的,节约空间
Volume sealed type transformer core is developed in recent years a new generation of low noise, low-loss transformer, the core of seamless, large reduction of the load loss and no-load current, so that no load current by 60% to 80%, high and low voltage winding around the pillar on the continuous system, winding tight, concentric. 10 dB above the noise down. As the core continuous winding, full use of the orientation of silicon steel, making the no-load loss reduced by 20% to 30%, which is a new generation of high-tech energy-saving environmentally friendly products. Sealed-type distribution transformers with non-suspended core structure, so internal and external fuel tank completely isolated, no storage cabinet, the transformer in the operation of thermal expansion changes in the elastic wave from the tank to do film shrinkage compensation, transformer oil and insulation conditions and outside air, water separation, transformer oil and thus slow down the aging rate of insulation parts. Seal oil tank with high-performance rubber, can be suspended in the field do not guarantee the core inspection run for 20 years, reducing operating maintenance costs and will help maintain the inconvenience of the place.
