Q&A:
What is the difference between a control box and a box-type transformer
The control box has only control functions. It is a control unit. Its main function is to issue instructions to control the rapid breaking of the circuit breaker in the box substation; it is a component in the box substation.
The box-type transformer generally refers to the box-type substation, which integrates the functions of power transformation, power distribution, control, and protection.
