Scope of Application

The regulator is an autotransformer whose output (end) voltage can be adjusted. There are two types of cores: the ring type and the column type. Column cores are similar to general transformers in that they are laminated with silicon steel sheets; ring cores are rolled with silicon steel tape. In the structure of the loop auto-regulator, the winding is wound on the ring core with a single layer of insulated copper wire. The surface of the coil part is ground away from the insulating layer to form a smooth surface, and a carbon brush made of copper-graphite composite is in contact with it. The carbon brush can be rotated on the surface of the wire by means of a hand wheel to change the output voltage. Current capacity greater than 10A, with two or more carbon brushes in parallel. Auto-connected regulators are generally made of self-cooled, dry type. In occasions with particularly large capacity or special use environments, there are also oil-immersed self-cooling systems. Three ring-type single-phase auto-coupling regulators are fitted together to form a three-phase auto-coupling voltage regulator.
Series LW-TDGC, TSGC2 single/three-phase voltage regulator series products are the fourteenth batch of energy-saving products for the electromechanical industry. Used in pressure regulating, temperature control, speed regulation, dimming, power control and other places, the use of a wide range, the product has a waveform is not distorted, small size, light weight, high efficiency, easy to use, reliable operation and other characteristics of its performance For superiority.
The coil is the main component of the regulator and it has the following properties:
1. The use of high magnetic permeability oriented steel, so the loss is small.
2. Using mechanical automatic winding, even between 匝 and ,, each line is straight and parallel, so the contact surface is flat.
3. Use a heat-resistant resin material to dip paint and cure to make the pressure regulator more heat-resistant.
4. Use mechanical grinding to make the contact surface smooth like a mirror.
5. With the traditional multi-carbon brush design, the contact surface of the carbon brush is increased, the current per brush is reduced, and the temperature rise is reduced.
6. Use high-performance carbon brushes to increase electrical conductivity and eliminate fire extinguishing.
7. Use copper surface welding to reduce contact resistance and reduce temperature rise.
8. The use of heat-resistant, elastic metal materials allows long-term stability of the mechanical pressure and reduces the temperature rise of the contact.
