JDZX9-35 voltage transformer (indoor)

Brand: US General Electric Company
Origin: USA United States
Advantages: Vacuum
features:
JDZX9-35 single-phase voltage transformer, indoor, fully enclosed dry-type products, the use of a set of three, JDZXs35 of Yo / Yo / C connection .JDZXFs-35 is Yo / Yo / Yo / connection. Rated frequency 50Hz or 60Hz, rated voltage of 35kV electrical metering energy power system for voltage monitoring and relay protection.
Second, conditions of use
1. altitude of not more than 3000 meters
2. The ambient temperature is not higher than + 40'C, not less than -5'C;
3. The ambient air relative humidity not more than 85% (20'C);
4. meet grade II;
5. Install non-corrosive gas sites
Third, the structure Introduction
JDZX9-35 voltage transformer for the indoor full vacuum casting epoxy structure, its surface creepage distance is greater than 25mm / kVe magnetic material with high permeability silicon steel surround, annealed. JDZX9-35 voltage transformer when the system is used to access Yo / Yo / C wiring, each need three, each transformer having a secondary winding two groups, one group was 0.2 (1a-1n) for metering. Another group made an auxiliary winding (da-dn), then an opening triple triangle, do grounding protection. JDZXF9-35 voltage transformer when the system is used to access Yo / Yo / Yo / C wiring, each need three, each combined transformer secondary winding having three groups, one group was 0.2 (1a-1n) for metering. Another group was 0.5 (2a-2n) for monitoring and control. Another group made an auxiliary winding (da-do), then into three triangular openings, do grounding protection. Measurement, monitoring, protection separately without disturbing each other, safe and reliable.
