XZ-B Substation Resonance Test Set

Transformer Gis System Sf6 Switch CT / PT Insulator Busbar Cable Bushing And Other Capacitive Equipment Are The Most Common Primary Electrical Equipment In Substations. According To The Test Regulation Of The Voltage Withstand Of Primary Electrical Equipment In 220kv (or <220kv) Substation The Corresponding Ac / Dc Voltage Withstand Test Equipment Should Satisfy Both The Test Conditions Of High Voltage And Low Current And Meet The Low Voltage And High Current Test Condition The Wide Application Range Is Required The Principle Of Series Resonance Is Adopted Composed By Frequency Power Source Excitation Transformer Reactor And Capacitive Voltage Divider .on The Capacitor Divider The Dc Voltage Withstand Test Can Be Completed By Connected With The Dc Rectifier And The Micro Ammeter. Because The System Has Good Filtering Characteristics After Resonance The Dc Voltage Produced By The System Is Better Than The Dc Voltage Rectified By The Common Test Transformer. It Is An Ideal Withstand Voltage Equipment For Local Municipal And County High Voltage Test Departments And Electric Power Loading Repair And Test Engineering Units.

Product characteristics

1. The Required Power Capacity Is Greatly Reduced. The Power Required For The Test Is Only 1/q Of The Test Capacity.
2. Small Size And Light Weight Generally 1/3-1/5 Of Common Test Equipment.
3. The Resonant Power Is Resonant Filter Circuit Which Can Improve The Distortion Of The Output Voltage And Get A Good Sine Wave Effective Prevention Of The Harmonic Peak On The Test Sample Of The Wrong Breakdown.
4. The Protection Function Of The Frequency Power Is Strong And The Stability Is Good.
5. It Has A Variety Of Working Modes And Convenient Operation.
6. Adopt 220v Or 380v Single-phase Power Supply To Facilitate On-site Power Collection.
7. The Configuration Is Flexible And The Expansion Function Is Strong.
