[0002] With the improvement of human living standards and the widespread application of electricity and electrical equipment, many places have strict requirements on power supply continuity and do not allow long-term power outages. Most of them use automatic transfer switches to ensure continuous power supply; automatic transfer switches automatically switch the load power supply circuit from an abnormal power supply to a normal second power supply (backup power supply), which is of great significance to the continuity and reliability of power supply.
[0003] There are some vulnerable components inside the existing transfer switches, such as micro switches, travel switches and other devices. These vulnerable components are usually dispersed or gathered and fixed inside the transfer switch by bolts and other parts. When the transfer switch electrical equipment undergoes transportation, construction, power installation, testing, including some temporary bridge lines of the construction power party, or due to damage to the quality of the product itself, it is easy to cause failure of vulnerable parts, which will be faced with maintenance and after-sales, especially for large-frame transfer switch electrical appliances, which can only be troubleshooted on-site after-sales.
[0004] In the prior art, vulnerable components inside the transfer switch are usually dispersed or aggregated and fixed inside the transfer switch by bolts and other parts. When vulnerable parts fail, the problem faced is how to conveniently, quickly and safely repair and replace some vulnerable components. However, the vulnerable parts are directly fixed inside the transfer switch, which makes the maintenance process cumbersome and difficult. Therefore, a modular transfer switch auxiliary box is proposed. Utility Model Content
