NAME:Jszw-10fr three-phase five-column anti-ferromagnetic resonance type voltage transformer.
Detailed introduction:

 Overview

 

This product is a three-phase five-column anti-resonance voltage transformer, which can effectively prevent the ferromagnetic resonance from burning the transformer. This product can still operate normally for a long time when the system has 100% ground fault, and the protection winding (da.dn) is generated. 100V voltage makes the relay action; it is suitable for voltage measurement and relay protection in AC 50Hz, rated voltage 10kV power system.

 

Executive standard:

 

l  GB20840.3-2013 "Transformers - Part 3: Supplementary technical requirements for electromagnetic voltage transformers"

l  JJG314-2010 "Testing Procedures for Voltage Transformers for Measurement"

l  GB311.1-2012 "Insulation coordination of high voltage power transmission and transformation equipment"

 

Conditions of Use:

 

l  The ambient temperature is between -5 ° C and 45 ° C, and the daily average temperature does not exceed 35 ° C;

l  Relative humidity: the daily average does not exceed 95%, and the monthly average does not exceed 90%

l  The altitude is not more than 1000 meters (please provide altitude when using at high altitude);

l  Installation type: indoor installation;

 

Technical Parameters:

 

l  Rated insulation level: 12/42/75kV;

l  Power factor cosΦ=0.8 (hysteresis);

Wiring schematic: 



 

 One N point is directly grounded, and the secondary winding (da, dn) is used for relay or microcomputer monitoring. This product is not allowed to repeatedly access the harmonic elimination device and the secondary microcomputer harmonic elimination device, otherwise the PT will be burned.

     Do not ground other points except one marked grounding point, otherwise the PT will be burned.
