magnetic voltage regulator is widely used in hot working industry. Do you know how a magnetic voltage regulator works? Why do we need magnetic type voltage regulators?
l What is a magnetic voltage regulator
l How does magnetic voltage regulator work?
l What is the characteristic of magnetic voltage regulator?
magnetic voltage regulator is a kind of no mechanical transmission, no contact voltage regulator, can drive the load for smooth stepless pressure regulation. Voltage regulation is controlled by DC current, can be open loop manual control, can also be realized according to different control signals closed-loop automatic control, it is the executive element of automatic control system.
1. The magnetic type voltage regulator is composed of transformer and saturated reactor. Its working process is to change the distribution ratio of the supply voltage in the transformer primary winding (WB1) and the reactor reactance winding (WG) by using the adjustable characteristic of saturated reactance, so as to achieve the purpose of adjusting the secondary output voltage.
2. The voltage regulation range of the magnetic voltage regulator is for the rated load resistance, if the actual use of the load resistance is not equal to the rated value, the voltage regulation range of the voltage regulator will change, especially in the lower limit area of voltage regulation, therefore, the general magnetic voltage regulator is not suitable for no-load voltage regulation.
3. The magnetic voltage regulator contains a saturated reactor. Due to its current limiting effect, the magnetic voltage regulator can obtain better drop characteristics, but the load voltage waveform of the magnetic type voltage regulator is distorted.
1. Due to the role of saturated reactor inside the magnetic modulation, the reactance device has limited current function, so it can obtain better falling external characteristics, overload capacity is strong, especially the load short-circuit capacity is incomparable to other transformers;
2. Magnetic modulation as the actuator, the time constant is large, so that the system is very stable, has a high anti-interference ability;
3. As a voltage regulating power supply equipment, under the condition of reasonable use, reliable and stable performance, can be regarded as permanent equipment;
4. Can be open loop manual control, can also be realized according to different control signals closed-loop automatic control;
5. Simple operation, high control precision, easy maintenance. Manual voltage regulation only need to rotate the potentiometer on the control box, you can adjust freely, temperature rise start fast, good thermal insulation effect, furnace temperature fluctuation in linear state, thus improving product quality, improve production efficiency.
We should pay attention to the above matters in the selection of magnetic voltage regulator, so as to avoid unnecessary trouble. If you are looking for a supplier of high quality magnetic voltage regulator at a reasonable price ,boyuan special transformer Co., Ltd. is a very good choice.
