Problems solved by technology
The CB level is generally operated by a motor to realize the closing and opening functions of the switch. This kind of mechanism has a complex structure. Due to the relatively large dust and humidity in the early use environment of the automatic transfer switch, it is easy to cause some parts of the complex mechanism to be stuck by dust. , causing the switch to fail to operate normally, resulting in a power failure, which greatly reduces the reliability of the automatic transfer switch
