摘要

为了满足电网中对252 kV罐式断路器三相机械联动的要求

需要对原LW24-252分相罐式断路器进行改进

利用原LW24-252产品的灭弧室结构

对传动部分进行改进。文中介绍了一种三相机械联动的设计方案

经测试

各项特性曲线包络线和原分相断路器进行比较

特性均相符要求

并通过型式试验验证

现已经在工程上得到应用。

Abstract

To meet the requirements of power grid for three-phase mechanical transmission of a 252 kV tank circuit breaker

conventional LW24-252 phase-separation tank circuit breaker was improved by amending its power train section but retaining its structure of arc-suppressing chamber. The measured characteristic curves of the improved circuit breaker were in accordance with those of the conventional products. Now the improved circuit breaker has passed through the type test and has been applied to engineering.
