Step-up transformer means to start the voltage instantaneously, and the step-up transformer instantaneously starts the step-up ability and the step-up effect is better. The difference is that the non-excitation voltage regulating switch does not have the ability to switch gears with load, because this kind of tap switch has a short-term disconnection process during the shifting of the gears, and disconnecting the load current will cause arcing between the contacts. The tap switch is broken or short-circuited, so the transformer must be powered off when adjusting gears. Therefore, it is generally used for transformers that do not require very strict voltage requirements and do not need to be adjusted frequently. Transformer is a common electrical equipment that can be used to transform a certain value of alternating voltage into another value of alternating voltage with the same frequency. A step-up transformer is a transformer used to transform a low-value alternating voltage into another higher-value alternating voltage with the same frequency. It is widely used in high-frequency fields, such as inverter power supplies.

Compared with oil-type transformers, dry-type step-up transformers do not have oil, so there is no fire, explosion, pollution, etc. Therefore, electrical codes and regulations do not require dry-type transformers to be placed in a separate room. Especially with the new series, the loss and noise have been reduced to a new level, creating conditions for the transformer and low-voltage panel to be placed in the same power distribution room. The safe operation and service life of dry-type step-up transformers largely depend on the safety and reliability of the transformer winding insulation. The winding temperature exceeds the insulation withstand temperature and the insulation is destroyed, which is one of the main reasons that the transformer can not work normally. Therefore, the monitoring of the transformer's operating temperature and its alarm control are very important. According to the characteristics of the use environment and protection requirements, dry type Different housings can be selected for step-up transformers. IP23 protective housing is usually used to prevent solid foreign objects with a diameter greater than 12mm and small animals such as rats, snakes, cats, and birds from entering, causing malignant failures such as short-circuit power failures, and providing a safety barrier for live parts. If you need to install the transformer outdoors, you can choose an IP23 protective enclosure. In addition to the above IP20 protective function, it can also prevent water droplets within a 60° angle to the vertical. However, the IP23 shell will reduce the cooling capacity of the transformer, so pay attention to the reduction of its operating capacity when selecting.
