基于JZ20-2平台SF6断路器使用安全性及改进措施分析

Security Analysis and Improvement Measures of SF6 Circuit Breakers Based on the JZ20-2 Platforms

为提高海上平台高压配电间安全性,减少SF6气体泄漏引发的人身伤害,分析JZ20-2中北平台配电间SF6高压断路器的使用现状及安全性,特别是SF6断路器泄漏气体特性及对人员危害性,指出平台现有SF6断路器配电间所存在的安全隐患,提出安全性改进意见,引进SF6气体在线监测系统,实现对配电间内SF6气体在线监测,保证平台人员人身安全。

The status and safety of SF6 circuit breakers on the JZ20-2 platforms are analyzed, especially with the character- istics and its damage of gas leakage of SF6 circuit breaker. The hidden dangers of SF6 circuit breaker in MCC are pointed out. The safety improvements are proposed for the existing situation and Introduced the concept of online monitoring of SF6 circuit breakers. The gas leakage of SF6 circuit breaker can greatly improve the safety factor in MCC and also reduced the personal injury.
