Quick access method for low-voltage drawer type emergency power supply
The invention discloses a quick access method for a low-voltage drawer type emergency power supply. An emergency power supply interface is fixedly arranged in a drawer unit; the emergency power supply door is provided with a lock consistent with a wire inlet frame circuit breaker, two locks and one key of the wire inlet frame circuit breaker and the emergency power supply door are achieved, the key is inserted into the wire inlet frame circuit breaker in a normal power supply state and cannot be pulled out, and operation cannot be conducted; the emergency power supply door is provided with a lock consistent with an operating handle of the molded case circuit breaker, so that the molded case circuit breaker and the emergency power supply door are locked by two locks and one key, and the molded case circuit breaker is in a switching-off state and the key is inserted into the operating handle in a normal power supply state. The emergency power supply interface device is modularized and standardized, can be quickly replaced or overhauled, and ensures power supply; the door of the emergency power supply room cannot be operated in a normal power supply state of a low-voltage system, so that tripping without reasons in the normal power supply state is avoided; a protection device is arranged between the emergency power supply and the power supply system main loop.
本发明公开了一种低压抽屉式应急电源快速接入方法，将应急电源接口固定设置在抽屉单元内；通过应急电源门配置与进线框架断路器一致的锁，实现进线框架断路器与应急电源门两锁一钥匙，正常供电状态下钥匙插在进线框架断路器上无法拔出、无法操作；通过应急电源门配置与塑壳断路器操作手柄一致的锁，实现塑壳断路器与应急电源门两锁一钥匙，正常供电状态下塑壳断路器处于分闸钥匙插在操作手柄上。本发明应急电源接口装置模块化、标准化，可快速替换或者检修，保证电力供应；在低压系统正常供电状态下无法操作应急电源室的门，避免正常供电状态下无故跳闸；在应急电源与供电系统主回路之间设置保护装置。
