箱式变压器并不只是变压器,它相当于一个小型变电站,属于配电站,直接向用户提供电源。包括高压室,变压器室,低压室;高压室就是电源侧,一般是35千伏或者10千伏进线,包括高压母排(High voltage busbar)、断路器或者熔断器、电压互感器、避雷器等,变压室里都是变压器,是箱变的主要设备,低压室里面有低压母排(Low voltage busbar)、低压断路器、计量装置、避雷器等,从低压母排上引出线路对用户供电。
Box transformer is not just a transformer, it is equivalent to a small substation, belongs to the distribution station, directly provide power to users. Including high-voltage chamber, transformer chamber, low-voltage chamber; high-voltage chamber is the power side, usually 35 kilovolt or 10 kilovolt incoming line, including high-voltage bus bar, circuit breaker or fuse, voltage transformer, arrester, etc., transformer chamber is the main equipment of box transformer, low-voltage bus bar, low-voltage circuit breaker and meter are in low-voltage chamber. Measuring device, lightning arrester and so on, from the low-voltage bus line out of the power supply to users.
箱式变压器的保护是专门保护变压器的,是集开发研制的集保护、监视、控制、通信等多种功能于一体的电力自动化高新技术产品,是构成智能化箱式变压器的理想电器单元。该产品内置一个由二十多个标准保护程序构成的保护库,具有对一次设备电压电流模拟量和开关量的完整强大的采集功能(电流测量通过保护CT实现)。
The protection of box transformer is specially designed to protect transformer. It is a high-tech product of power automation, which integrates protection, monitoring, control, communication and other chengde.75ix.cnwww.xiangsuhejin.cnwww.handanbaojie.net.cnwww.chengdebanjia.cnfunctions. It is ceshiyig.89ix.comfeidianlan.07858.netan ideal electrical unit of intelligent box transformer. The product has built-in a protection library composed of more than 20 standard protection programs, which has a complete and powerful acquisition function for voltage and current analog and switching quantities of primary equipment (current measurement is realized by protective CT).
