The Introduction of Energy Meter’s Part-Transformer
The electric power system is a complex system that produces and provides electric energy and meets the social demand for electric power.The power generation, transmission, distribution and electricity use links adopt different voltage levels, and the transformation and connection between voltage levels are realized through the transformation link. Among them, transmission and transformation link uses high voltage equipment, distribution link uses medium voltage equipment, civil link uses low voltage equipment.
Transformer is a device, which uses the principle of electromagnetic induction to change the ac voltage. The main components of Transformer are the primary coil, the secondary coil and the core (magnetic core). Its main functions are: voltage, current, impedance, isolating voltage regulator (magnetic saturation transformer), etc.
Transformers can be divided into: sealed transformer, PIN transformer, flyback transformer, combined transformer, dry transformer, oil-immersed single-phase transformer, electric furnace transformer, rectifier transformer and so on. Today we mainly talk about the transformer in the application of electricity meters:
1. Sealed transformer: This series of transformers are widely and mainly used in a variety of high-end high-precision small instruments and meters, such as: electric meter instrument controller.
Particularly recommended fully sealed power transformer (epoxy potting, plastic shell) imported cold rolled silicon steel sheet material, with high efficiency, low consumption, reliable operation, nice appearance of environmental protection, low noise, insulation performance is good, have the effect of the moisture proof, water proof and dust proof. Therefore it can be widely used in all kinds of high precision small instrument which leads to the foot can be directly welded on the PCB, this series of products using professional fully automatic winding machine, and vacuum filling and sealing machine batch production, ensure the stable quality of product performance and consistency.
2. Pin transformer: It can be composed of independent standard lamination circuit or small multi-layer PCB board components, or integrated into the power multi-layer PCB board PCB plane transformer has a small shape and volume, excellent heat dissipation performance, very low leakage, excellent performance repeatability.
3.High Frequency Flyback Transformer is a power transformer whose working frequency exceeds that of intermediate frequency (10kHz). It is mainly used for high-frequency switching power transformer in high-frequency switching power supply. It is also used for high-frequency inverter power supply and high-frequency inverter welding machine to make high-frequency inverter power transformer in high-frequency switching power supply.
