Using Methods and Attention Matters

1.Check the test transformer measuring winding rated output voltage, and make it match the operation box correctly.

2. Connect the line between test transformer and operation box according to the wiring diagram.

3. Switch on the power supply, then close the knife switch, and the power indicator light, finally set the work time of relay.

4. Make the pressure regulator display zero, press the start button, the clockwise rotation of the hand wheel, until it reaches the required value.

5. Start the timing switch, timing begins, the electric bell will alarm automatically when it reaches the setting time(artificially controlled time if there is on alarming function), then break off the timing switch.



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.
