 Nowadays, whether it is a refrigerator in the living room, or a first-class electrical appliance in the kitchen of the dining room is not strange, with their requirements getting higher and higher, more new product selection appliances should be born from time to time, but no matter what kind of product, his occurrence is to better deal with everyone's life problems. I don't know if you have heard of it, but now there is a new word, called inverter governor, so what is inverter governor? What should be paid attention to in the process of using inverter governor?

   What is a variable frequency governor?

1. Inverter governor is an electrical equipment used to change the frequency of alternating current. In addition to this, it also has the function to change the operating voltage of the AC current.

2. In the past, inverter governors were generally included in electrical equipment such as motor generators and rotary converters. With the birth of semiconductor material electronic products, we have been able to produce and manufacture the most advanced frequency converter.

3. For the frequency converter that requires a large number of calculations, such as closed-loop control frequency conversion governor, sometimes a CPU and some corresponding power supply circuits that carry out rotation distance calculation are also required, and the AC motor speed regulation is to change the number of times the power supply system of the rotor winding of the motor to achieve the effect of speed change.

Precautions for the use of inverter governor?

1. Be sure to use the frequency converter reasonably

2. Read the product manual carefully, and wiring, installation and application in accordance with the provisions of the manual.

3. The frequency conversion governor equipment should be reliable grounding device to suppress radio frequency interference and avoid electric shock caused by the frequency conversion governor due to electric travel.

4. Use the frequency conversion governor to control the motor, and the temperature and noise of the motor will be higher than that of the power grid (DC) when the speed ratio is high: when running in low speed gear, due to the low speed ratio of the fan blades of the motor, attention should be paid to ventilation and refrigeration and its moderate load relief, so as to prevent the motor from heating up beyond the specified value.

5. The characteristic impedance of the power supply line should not be too small. When the volume of the distribution transformer exceeds 500KVA or the volume of the distribution transformer exceeds 10 times the capacity of the frequency conversion governor, or when the frequency conversion governor is connected to a place very close to the distribution transformer, because the impedance of the control loop characteristics is small, the capital investment will cause a very large surge protection to the frequency converter in an instant, and the rectifier components of the frequency conversion governor will be destroyed.

6. When the three-phase voltage unbalance rate of the power grid exceeds 3%, the relatively high value of the input current of the frequency conversion governor is very large, which will lead to the overtemperature of the frequency conversion governor and the connection or damage to the electronic components. In particular, when the transformer is a V-shaped wiring method, it is more serious, in addition to modifying the reactor on the AC side, it is necessary to modify the DC reactor on the DC side.
