STS静态切换开关

　　1 概述Overview：

　　STS静态切换开关是由电子开关（SCR、GTR）实现双路输入一路输出的快速切换装置，通过两路输入互为备份快速切换的工作状态，来保障重要负载不掉电。

　　The Static switching switch（STS） is a rapid switching device that utilizes electronic switches (SCR, GTR) to achieve dual input and single output. It ensures that critical loads remain powered by rapidly switching between two input paths, with each serving as a backup for the other.

　　7 STS使用说明STS User Manual

　　7.1 STS投运说明STS commissioning instructions：

　　7.1.1 STS使用时，1路输入、2路输入、输出，均需加断路器，以实现分闸和合闸状态。

　　When using STS, circuit breakers are required for both 1 input, 2 input, and output to achieve the open and closed states.

　　7.1.2 STS接好通电导线，合上1路输入、2路输入、输出断路器，STS即刻运行，断路器合闸不分先后顺序。

　　Connect the STS to the power lead, close the circuit breakers for 1-way input, 2-way input, and output, and the STS will start running immediately. The closing of circuit breakers does not have a specific order.

　　7.1.3 用户可以通过‘优先级按键’自行设置主、备供电状态。

　　Users can set the main and backup power supply statuses themselves through the‘priority button'.

　　7.1.4 STS运行时，液晶触摸屏、指示灯均会显示其工作状态。

　　When STS is running, both the LCD touch screen and indicator lights will display its working status.

　　7.1.5 如遇异常，液晶触摸屏会显示其故障状态及信息、相应指示灯会转为红色显示故障状态，并伴有声音报警。

　　In case of an abnormality, the LCD touch screen will display its fault status and information, the corresponding indicator light will turn red to indicate the fault status, and an audible alarm will sound.

　　7.1.6 在异常状态下，声音报警90s后自动消除，或人为按‘消音键’消除，但液晶触摸屏和指示灯仍会显示故障信息和故障状态。异常消除后，液晶触摸屏显示正常运行状态和显示正常运行信息，指示灯转为绿色正常运行状态。

　　In abnormal conditions, the audible alarm will automatically cease after 90 seconds, or can be manually silenced by pressing the‘mute button'. However, the LCD touch screen and indicator lights will still display fault information and fault status. After the abnormal condition is resolved, the LCD touch screen will display the normal operating status and information, and the indicator lights will turn green to indicate normal operation.
