Single-phase contact voltage regulator

Overview of Contact Voltage Regulator:

The contact voltage regulator is wound with an imported silicon steel sheet ring iron core, which is wound with a single pressure. Several carbon brushes installed on the brush holder closely coincide with the polished surface of the coil under the spring pressure. The motor drives the carbon brush to slide on the polished surface of the coil for voltage adjustment. If automatic voltage regulation is required, a voltage value (a fixed point can be set arbitrarily within the adjustment range) can be preset. A potentiometer can be adjusted to the required voltage point. The set voltage value can be observed through an external voltmeter. After the voltage value is set, the voltage regulator will automatically adjust to the set voltage. If the external voltage fluctuates, it can also automatically adjust the stable voltage. The intelligent voltage regulator * * It is equipped with a voltmeter and ammeter, which can monitor the operation status in real time. It is also equipped with manually adjusted step-up and step-down buttons, which is convenient to use, low loss, high efficiency Small magnetic leakage, low noise, strong instantaneous overload capacity, and no waveform distortion make it an ideal choice for scientific research, testing, and other equipment.

Basic principles
A voltage regulator is an autotransformer with continuously adjustable turns ratio. When the voltage regulator brush slides along the polished surface of the coil with the help of the handwheel spindle and brush holder, the turns ratio can be continuously changed, thereby smoothly adjusting the output voltage from zero to * * value

Product Features
1. High magnetic conductivity oriented straight silicon steel sheets are used, resulting in low losses.
2. Mechanical automatic winding is adopted, with even turns between turns, and each line is straightened and parallel, resulting in a smooth contact surface.
3. Use heat-resistant resin materials to coat, cure, and make the regulator more heat-resistant.
4. Use mechanical grinding to make the contact surface smooth like a mirror.
5. Adopting traditional multi carbon brush design increases the contact surface of the brushes, reduces the current borne by each brush, and lowers temperature rise.
6. Use high-performance electric brushes to increase conductivity and eliminate sparks.
7. Copper surface welding is used to reduce contact resistance and temperature rise.
8. Using heat-resistant elastic metal materials to ensure long-term stability of mechanical pressure and reduce temperature rise during contact.
