Abstract: In recent years, the traditional breaker and switch in substation are face to renew and replace. So the electric equipment mechanism box need to be dismantled and replaced. Formerly, the mechanism box replacement needs four workers to cooperate by manual. It wastes time and energy and It's dangerous. Design a substation equipment mechanism box which can control the levelness. It's an intelligent device with four corner levelness monitoring function. It's small size and light weight. It supports automatic lifting. It adopts crawler-type lifting and easy to install. It's easy to operate and obtains good application results.
