电是清洁、高效、方便的能源,它的应用,给人类带来了巨大的好处,但如果使用不当,也会发生电器过载、电击(触电)或火灾等事故,造成人身伤亡或重大经济损失。 1.合理的电气设计是电气安全保护的基础 (1) 配电系统 低压配电线路保护是为了在电气故障时,能够防止人身遭到电击、电气线路损坏和电气火灾。合理的配电系统能够保证故障时迅速地、有选择性地切断故障点电源,避免事故扩大并造成损失。
Electricity is a clean, efficient and convenient source of energy. Its application has brought great benefits to human beings. However, if it is not used properly, accidents such as electrical overload, electric shock (electric shock) or fire may occur, resulting in personal injury or death or significant economic loss . 1. Reasonable electrical design is the basis of electrical safety protection (1) Distribution system Low-voltage distribution line protection is to prevent personal electrical shock, electrical damage and electrical fire. Reasonable distribution system to ensure that failure promptly and selectively cut off the power point of failure, to avoid accidents and cause damage.
