讲到双电源自动转换开关调试的方法，我们继续讲关于双电源自动转换开关使用注意事项有你哪些及安装方法。
We talk about the method of adjusting the dual power automatic switching switch. We continue to tell you what and how to install it.
一、首先让我们了解下它的作用是什么？
First, let us know what is the function of it.
当因事故停电，且在较短时间内无法恢复供电时，必须启用备用电源。
When power supply is not restored in a short time due to a blackout of the accident, a standby power supply must be enabled.
步骤：
Step:
切除市电供电各断路器(包括配电室控制柜各断路器，双电源切换箱市供电断电器)，拉开双投防倒送开关至自备电源一侧，保持双电源切换箱内自备电供电断路器处于断开状态。
The circuit breaker (including the switchboard, the control cabinet, the circuit breaker, the double power switch box, the city power supply breaker) is cut off, and the double switch anti switching switch is opened to the side of the self powered power supply, so that the self powered electric circuit breaker in the dual power switch box is in a state of disconnection.
启动备用电源(柴油发电机组)，待机组运转正常时，顺序闭合发电机空气开关、自备电源控制柜内各断路器。
To start the standby power supply (diesel generator), when the standby unit operates normally, the air switch of the generator and the circuit breakers in the self-contained power control cabinet are closed.
