在了解高压开关柜之前,首先我们要了解到,环网柜是开关柜的一种,而开关柜因为电压的不同,被分为高压与低压,高压的开关柜又因为其功能的不同,有被分为高压环网柜、高压中置柜等,其中高压环网柜又被分为很多种,高压环网柜是为提高供电可靠性,使用户可以从两个方向获得电源,通常将供电网连接成环形。这种供电方式简称为环网供电,而进线柜均所指为变压器低压10kV环网柜河南体彩快赢481走势图。即由变压器低压侧输出连接至10kV母线的初始端的第一个柜:称为进线柜,也称为变低进线柜。

环网柜的原理

是为了实现线路互供,即不同的线路从不同的变电站出来后,互相拉手,正常情况下联络断开,各自运行,但一旦某个变电站停电,就可以把停电的变电站的由变电站线路断开,把联络合上,让另一个变电站带原本由原变电站带的负荷。或者某个线路或变电站带负荷过高,而另一个带负荷过低,则可以有选择性的从某个联络点断开,由负荷较低的线路或变电站来带分担一部分负荷,这样既保证了供电的可靠性,也保证了电网的稳定运行。

环网柜的应用环境分类

环网柜根据应用的环境可以分为户内环网柜和户外环网柜。户内环网柜是用于高压侧的配电,必要时户内环网柜也可以安装断路器,以保证电网的顺利安全通断。户内环网柜主要由进线柜、计量柜、PT柜、变压器出线柜等组成。
