XGT9-12箱型固定式交流金属封闭开关设备

产品概述 Product Features

开关柜母线室与电缆室通过负荷开关{或断路器)本体的金属底架隔成。因此符合LSC2类开关柜的要求;
开关柜配用的负荷开关(或断路器)的每一相所有带电零部件均由单个绝缘套管支撑,结构紧凑;
操作及“五防”联锁机构集成在操动机构箱内,采用应答式操作步骤设计,防误操作直观可靠;
断路器与负荷开关外形尺寸完全相同,便于开关柜的扩展和组合。
开关柜可靠墙安装;
可配装自供电数字继电器。

The bus cabinet and cables cabinet is isolated by the metal frame of the circuit breaker, thus, it conform to the requirements of LSC2 circuit breaker.
The switchgear with the load switch (or the circuit breaker),its live parts in every phase are supported by the single insulated bushing, very firmly;
Operation device and “Five preventions” interlocks mechanism are integrated together inside the operation cabinet, which adopts the response type and design, faultless operation is reliable;
The size of the circuit breaker and the load switch are the same, it is convenient for the switchgear to extend and combine.
Switchgear Wall Installation
Equipped with the self-powered digital relay.
