Outdoor high voltage AC SF6 circuit breaker
LW36-126 户外高压交流六氟化硫断路器

概述 /Overview

LW36-126/3150-40 型自能式交流高压六氟化硫断路器为户外型产品，适用于海拔不超过
2000 米 ( 可设计海拔 3000 米以上产品 )，环境温度不低 -40℃，污秽等级不高于 IV 级地
区的交流 50Hz，最高电压为 126kV 的电网中，用以切断额定电流、故障电流或转换线路，
实现对电力系统的控制和保护，也可作为联络断路器使用。
该产品以 SF6 气体作为灭弧和绝缘介质，采用了国际最先进的自能式灭弧技术，配用新型
的弹簧操动机构，具有电寿命长、操作功小、噪声低、可靠性高等特点，其结构简单、体积小，
不检修周期长，在目前电力设备趋向无油化、大容量的进程中，可完全替代同类型的进口
产品。
LW36-126/3150-40 self-energizing AC high voltage sulphur hexafluoride circuit
breaker is an outdoor product, suitable for altitudes up to 2000 meters (can be
designed for products above 3000 meters above sea level), ambient temperature is
not lower -40℃ , pollution The level is not higher than the AC 50Hz in the IV level, and
the maximum voltage is 126kV. It is used to cut off the rated current, fault current or
conversion line to realize the control and protection of the power system. It can also
be used as a contact breaker.
The product uses SF6 gas as arc extinguishing and insulating medium. It adopts the
most advanced self-energy arc extinguishing technology in the world, and is equipped
with a new spring operating mechanism. It has long electrical life, small operating
power, low noise and high reliability. The utility model has the advantages of simple
structure, small volume and long maintenance period. In the current process of power
equipment becoming oil-free and large-capacity, it can completely replace the same
type of imported products.
