Internal structure of induction voltage regulator

The induction voltage regulator usually consists of two parts: the main magnetic circuit and the secondary regulating winding. The main magnetic circuit is composed of one or more magnetic cores, and the secondary regulating winding is wound on the main magnetic circuit. The internal structure of the induction voltage regulator is as follows:

1. Main magnetic circuit: The main magnetic circuit is the core part of the induction voltage regulator, which consists of one or more magnetic cores. The material of the magnetic core is usually silicon steel sheet or sendust. The main magnetic circuit includes a main winding. After the induction voltage regulator is turned on, the main winding is excited by the AC power supply to form a magnetic flux in the main magnetic circuit.

2. Secondary regulating winding: The secondary regulating winding is a winding wound on the main magnetic circuit, usually composed of a live torch. When the main winding starts to receive the current feedback signal in the secondary regulating winding, the magnetic flux of the main winding will be controlled to control the output voltage.

3. Capacitors: Inductive regulators sometimes use capacitors to maintain a stable output voltage. When the load changes suddenly, the capacitor can provide additional short-term energy to stabilize the voltage.

4. Control circuit: The inductive voltage regulator also includes a control circuit to ensure that the inductive voltage regulator can work correctly. The control circuit usually includes some sensors and comparators, as well as rheostats or other electronic components for regulating voltage and current.

In short, the internal structure of the induction voltage regulator is relatively complex, mainly including the main magnetic circuit, secondary regulating winding, capacitor and control circuit, etc. Each part plays a very critical role and is indispensable in the function of the entire induction voltage regulator.

Working conditions of induction voltage regulator

Under the following conditions, the product can operate continuously for a long time.

1. The altitude shall not exceed 1,000 meters;

2. The ambient medium temperature is not higher than +40℃ and not lower than -25℃;

3. The relative humidity of the air shall not exceed 85℅;

4. In an environment without chemically corrosive gases and steam;

5. In a gas environment without explosion hazard;

6. Temperature rise standards are: oil surface temperature rise 55°C (when the ambient medium temperature is 40°C, the maximum oil surface temperature is not allowed to exceed 95°C), winding temperature rise 65°C, and core temperature rise 80°C.

Inductive voltage regulator function

The inductive voltage regulator has two main functions:

1. Adjust output voltage: The induction voltage regulator mainly adjusts the output voltage by changing the magnetic flux of the main magnetic circuit. When the main winding in the induction voltage regulator is connected to the power supply, a magnetic field is generated. At this time, the current induced in the secondary regulating winding in turn affects the main magnetic circuit, thereby changing the magnetic flux and magnetic field strength, so that the output voltage can be adjusted to the required value.

2. Control the starting current: The induction voltage regulator can control the starting current of the motor when it starts, so that the motor can avoid damage and noise caused by impact current during operation.

Inductive voltage regulators are widely used for voltage stabilization and starting of equipment such as motors, chillers, material conveyors, pumps and industrial fans. Compared with power electronic technology equipment such as silicon-controlled rectifiers and inverters, inductive voltage regulators are low-cost, easy to install, and do not generate electromagnetic interference, so they have special advantages in some special scenarios.
