焊管高频电力设备的继电保护问题与改进建议

Relay Protection and Improvement Suggestion for HF Electrical Equipment of the Welded Pipe

我国焊管高频电力设备在继电保护技术方面重视不够。有的不设置标准过流保护装置 ,有的只设置简单的二相式二只电流继电器过流保护装置 ,这样往往起不到过流保护作用 ,从而损坏设备 ,影响企业的生产。分析了目前存在的现状 。

Enough stress is not laid on the relay protection technique for HF electrical equipment of the welded pipe in our country. Some do not set up the reference over-current protection units, some only install a simple two-phase type two current relay over-current protection units, which of them can not function for the over-current protection , and damage equipment and affect the enterprise production. This paper analyses the existing problems at present and makes several improvement suggestion.
