The difference between dry regulator and oil regulator

Oil Regulator: Also known as a non-contact inductive regulator or a smart contactless regulator (only the name of the company's own selling point).

advantage:

1, no contact, maintenance-free, impact resistance (special moment impact, is twice the normal. The reason is that the reaction is slow, it is through oil cooling, to achieve the purpose of heat dissipation, but oil cooling takes time)

2, high power, low price, good overall stability, but high cost of use;

3, no environmental interference, can work in high temperature or humid environment (can work normally at high and low temperatures);

Disadvantages:

1, the loss is large, the reaction speed is slow

2, the noise is large, 60-80 decibels;

3, there are waveform distortion of about 1-3%;

4, not environmentally friendly, large volume (because of the large loss of the oil regulator, most of the lost energy is converted into heat, which requires the oil regulator to have a good heat dissipation effect, which is also oil-type stability The reason for the large volume of the press) is that the temperature rises and is not safe.

Note: The oil regulator is limited to more than 60KVA (in fact, the power of the oil regulator can also be small, but the cost per KVA is not competitive with the dry regulator). The oil regulator is suitable for dusty and sundries, high ambient temperature (above 70 degrees), and places where sealing is required, such as metallurgy industry, stamping industry, furniture industry, glass industry, etc.
Dry voltage regulator (D/SBW compensating voltage regulator, there is a unified standard, the market share of products above 60KVA is over 95%)

advantage:

1. Wide voltage regulation range, high voltage regulation accuracy, high efficiency, low loss, no waveform distortion, energy saving and long life;

2, small size, environmental protection, low noise;

3. When the voltage is fluctuated due to input or load voltage change, it can quickly and automatically maintain the stability of the output voltage, strong impact resistance, can withstand instantaneous overload, and can work continuously for a long time;

4, perfect protection function: over-voltage, under-voltage, over-current, overload, phase loss, phase, phase sequence, short circuit, lightning protection, surge, mechanical failure and other automatic protection devices are complete (the above functions can be selected);

5, input / output voltage in phase, manual / automatic bypass switching, easy to use, safe and reliable operation;

6, the technology is mature and stable, can be customized according to user requirements for three-phase split type, stable and integrated.

Disadvantages:

1. Maintenance is required. Generally, maintenance is carried out once every six months to once a year according to the site environment.

2. Short-term impact resistance and long-term load capacity are not as good as oil regulators.
