Product Description

JDZ-10 voltage transformer is a special transformer, which has the triple function of transformer voltage transformation, impedance transformation and electrical isolation. The relay protection device realizes the functions of measurement, metering and protection.

product advantages:

1. Small size.
2. It has good insulation performance and moisture-proof performance.
3. Easy to install, suitable for any location and any direction.
4. The technology is mature and the products are relatively stable.

Structure
The voltage transformer mainly adopts epoxy resin fully enclosed casting structure, and the primary winding, secondary winding and iron core of the transformer are poured together.

The structure of JDZ-10 voltage transformer double-winding and three-winding voltage transformer:

The voltage transformers used for measurement are generally made into a single-phase double-winding structure. When the insulation levels at both ends are the same, they can be used in single-phase or combined for three-phase use. The main technical requirement for this voltage transformer is to ensure the necessary accuracy level.

The voltage transformer for ground protection also has an auxiliary secondary winding, which is called a three-winding voltage transformer. The three-phase auxiliary secondary winding forms an open triangle. Once the neutral point is displaced when the system is single-phase grounded, a zero-sequence voltage will appear on the auxiliary secondary winding, so the auxiliary secondary winding is now called a zero-sequence voltage line group.

Three-winding voltage transformers are generally made into single-phase, and when made into three-phase, a three-phase five-column (three-phase three-column side-choke) core should be used, and the voltage is 10kv and below, which is to provide zero-sequence magnetic flux. circuit. For this kind of voltage transformer, the accuracy level of the zero-sequence voltage winding is not high, generally 3B or 6B, to ensure that the voltage of the open triangle terminal is within a certain range, but it is required to have certain overexcitation characteristics.
