Study on the Setting Scheme of DC Breaker of Railway Leaky Coaxial Cable
摘要
Abstract
To solve the problem of damages to DC breaker of leaky coaxial cable(LCX) due to improper setting and installation of DC breaker in electrified railways,setting schemes of DC breaker are studied. Firstly, the electrostatic induction voltage and electromagnetic induction voltage are calculated, and examples are presented. Secondly, the necessities and functions of DC breaker are analyzed. Finally, recommended setting scheme is proposed after comparison. One DC breaker is installed at one end of the LCX each every 500~750 meters to prevent DC and low frequency current from passing through the LCX and to avoid the electromagnetic induction of the LCX exceeding the limit specified in the corresponding standards. The other end is grounded to prevent and eliminate electrostatic induction for the protection of people and equipment.关键词
