JDZ10-10 3kV 6kV 10kV Single Phase PT Protection Relays Voltage Transformer

Structure of JDZ10-10 single phase voltage transformer

A voltage measurement transformer is a transformer with an iron core. It is mainly composed of primary and secondary coils, iron core and insulation. When a voltage U1 is applied to the primary winding, a magnetic flux φ is generated in the core. According to the law of electromagnetic induction, a secondary voltage U2 is generated in the secondary winding. Changing the number of turns of the primary or secondary winding can produce different ratios of primary voltage and secondary voltage, which can form voltage transformers with different ratios. The voltage transformer converts high voltage into low voltage in proportion, that is, 100V. The primary side of the voltage transformer is connected to the primary system, and the secondary side is connected to measuring instruments, relay protection, etc.; it is mainly electromagnetic (capacitive voltage transformer application Widely), and there are non-electromagnetic types, such as electronic and photoelectric types.

Features of voltage transformer:
1. Small size.
2. Has good insulation and moisture-proof properties.
3. Easy to install, suitable for installation in any location or direction.
4. The technology is mature and the products are relatively stable.

Environmental conditions:
1. The altitude does not exceed 3,000 meters;
2. The ambient temperature should not be higher than +40’C and not lower than -5’C;
3. The relative humidity of the surrounding air is not greater than 65% (20’C);
4. Meet Level II pollution level;
5. There is no corrosive gas in the installation site
