1. To carry out work in all and part of the energized panels, the equipment should be overhauled and separated from the operating machinery and equipment with obvious markings.
2. The secondary winding of the voltage transformer and the transformer should have reliable grounding maintenance.
3. When working on the secondary circuit of the running voltage transformer, the following safety precautions should be taken:
4. Stop the current circuit from being cut off.
5. In order to reliably short-circuit the secondary solenoid coil of the voltage transformer, it is necessary to select short-circuit defect pieces and short distances, and prohibit the transmission line surrounding.
6. Do not do any work on the control circuit and transmission line between the voltage transformer and the short-circuit faulty terminal.
7. Insulating things should be selected, insulated things should be worn, and if it is necessary to stop using relevant relay maintenance before operation.
8. When connecting the temporary load, it must be equipped with a special power switch and circuit breaker.
9. During the secondary circuit plug-in experiment, in order to prevent the secondary side from the primary reverse transformer, in addition to breaking the secondary circuit, the next circuit breaker should also be selected.
10. Before the secondary circuit is plugged in or the AC withstand voltage test, the maintenance workers and relevant personnel should be notified, and soldiers should be sent to guard the scene, check the control circuit, and confirm that no one is working before it can be charged.
11. Check the relevant staff of power-off maintenance and secondary circuit, and stop any reverse operation without the consent of the staff.

Low-voltage cabinet for capacitance compensation – Wienal
Capacitor compensation is indispensable in low-voltage cabinets, so what is the effect of capacitor compensation. The meaning of this is that it acts as a capacitor. Let's take a look at the principle of capacitor compensation first, when the capacitor is compensated, the capacitor and the load are connected in parallel, and the capacitor is like a bin. When the load increases, the power supply has internal resistance, so that ...
