摘　　要：继电保护开关电源主要应用于恶劣环境,因此与普通电源相比具有更高的设计标准和更特殊的设计要求。继电保护开关电源的特殊性决定了必须要有相应的策略来保障其安全。继电保护开关电源本身是为了保护电力传输不受外界干扰,如果出现故障,将会引发一系列问题,如大型停电事故。但是,继电保护开关电源在使用中难免会出现一些问题。作为一种特殊的开关,它的故障原因也存在特殊性。如何避免这些故障和在故障出现后如何解决这些问题对,电力行业的发展至关重要。因此,分析继电保护开关中的常见故障,并提出了相关的改进建议。Relay protection switching power supply is mainly used in harsh environment.Therefore,compared with ordinary power supply,relay protection switching power supply has higher design standards and more special design requirements.The particularity of available switching power supply for relay protection determines that corresponding strategies must be adopted to ensure the safety of relay protection switching power supply.Relay protection switch power supply itself is to protect the power transmission from external interference,if the relay protection switch power supply fails,it will cause a series of problems,such as a large power outage.But in the use of relay protection switch power supply will inevitably appear some problems,as a special switch,relay protection switch power supply fault causes also have special characteristics,how to avoid these faults and how to solve these problems after the failure has an important impact on the development of the power industry.This paper will analyze the common faults in relay protection switches and give some Suggestions on how to improve these faults.
