YDTC Series Cascade Dry-Type Test Transformer
1. YDTC-150/375I Series Dry-Type Test Transformer
• Model Meaning:
◦ YDTC: Y (Test), D (Voltage), T (Transformer), C (Cascade), represents a modular cascade dry-type test transformer.
◦ 150/375I: Rated voltage 150 kV, rated capacity 375 kVA. It is a two-stage cascade structure (single stage 75 kV, two stages combined can reach 150 kV).
• Core Structure:
The epoxy resin-filled insulation cylinder has high insulation strength and no local discharge characteristics, making it suitable for conducting local discharge tests.
The large-diameter metal cover at the top is a high-voltage pressure equalizing cover. The annular pressure equalizing ring in the middle is used to optimize the electric field distribution and suppress corona and local discharge.
• Main application:
It provides high-amplitude power frequency high voltage for power equipment, which is used for power frequency withstand tests and partial discharge detection of insulators, transformers, cables, etc. It is a key device for verifying insulation levels and detecting internal defects.
2. Equipment with a pressure equalization ring on the left side: High-voltage capacitor voltage divider
• Structural feature: Multi-level metal equalizing ring + red insulating support column, connected to the high-voltage terminal of the test transformer through high-voltage leads.
• Core Function:
Divide the high voltage of several thousand kilovolts into lower voltage signals at a fixed ratio, output which can be measured, precisely record the amplitude and waveform of the test voltage, simultaneously improve the electric field distribution of the measurement circuit, suppress interference, and ensure the accuracy of the test data.
