Many of our clients doubt how to regulate voltage for unexcited Oil immersed transformer, now let us check how to regulate voltage for unexcited Oil immersed transformer clearly.
When adjusting the gear of the oil immersed unexcited transformer, it is necessary to cut off the power first, which is also for the safety of life. After the power distribution is disconnected, a load will occur on its low-voltage side. At this time, we can directly pull the fuse through the insulating plate and do a good job. security measures. Find the protective cover of the tap changer, try to unscrew it, and then adjust it to the neutral position. Then adjust the gear position according to the output voltage value, adjust the tap switch, and turn it to the designated position. If the output voltage of the transformer is lower than the allowable value, the position of the switch needs to be adjusted from the first gear to the second gear, that is to say, it needs to be upgraded, and the second gear can also be adjusted to the third gear. If the voltage sent to the low-voltage electrical appliances is relatively low, it can be adjusted to a high position at this time, and vice versa.
