Oil Regulator: Also known as non-contact inductive regulator or intelligent non-contact regulator (only the name of the company's own selling point).
Forte:
1. No contact, no protection, impact resistance (especially instantaneous impact, 2 times of normal.) The reason is that the response is slow, it is cooled by oil to achieve the purpose of heat dissipation, but oil cooling takes time)
2. High power, low price, good overall stability, but high cost;
3. No environmental disturbance, able to operate in a high temperature or humid environment (normal operation in uneven temperature);
Shortcoming:
1. Large loss and slow response
2. High noise, 60-80 decibels;
3. There is about 1-3% waveform distortion;
4. It is not environmentally friendly and large in size (due to the large loss of the oil regulator, most of the electrical energy lost is converted into heat, which requires the oil regulator to have a good heat dissipation effect, which is also the reason for the large volume of the oil regulator), the temperature rises, and it is unsafe.
Note: The oil regulator is only limited to more than 60KVA (in fact, the power of the oil regulator can also be small, but its cost per KVA is high, and the dry regulator is not competitive). The oil regulator is suitable for dust, sundries, high ambient temperature (above 70 degrees), and places that require sealing, such as metallurgical occupation, stamping occupation, furniture occupation, glass occupation, etc.
Dry voltage regulator (D/SBW compensating voltage regulator, with consistent standards, more than 95% of the market share of products above 60KVA)
Forte:
1. Wide voltage stabilization scale, high voltage stabilization accuracy, high efficiency, low loss, no waveform distortion, power saving and energy saving, and long life;
2. Small size, environmental protection, low noise;
3. When the voltage fluctuation is caused by the change of input or load voltage, it can quickly and actively adhere to the stability of the output voltage, has strong impact resistance, can withstand instantaneous overload, and can operate continuously for a long time;
4. Perfect protection function: overvoltage, undervoltage, overcurrent, overload, phase loss, phase error, phase sequence, short circuit, lightning protection, surge, mechanical fault and other active protection devices are complete (the above functions can be selected);
5. The input/output voltage is in the same phase, manual/active bypass switching, easy to use and install, safe and reliable operation, etc.;
6. The skills are proficient and stable, and the three-phase sub-modulation type and the integrated type of stability and change can be customized according to the requirements of users.
Shortcoming:
1. The short-term impact resistance and long-term load capacity are not as good as those of oil regulators.
2. It needs to be protected, and it is generally maintained and protected once a year from half a year to the on-site environment.
