The core advantage lies in the exclusive dry-type transformer test module. The built-in temperature rise load test system can simulate the actual operating conditions of dry-type transformers and accurately detect the winding temperature distribution. The partial discharge test module optimizes the detection algorithm for the insulation structure of dry-type transformers, effectively shielding environmental electromagnetic interference and improving test accuracy. It adopts an integrated design, without the need for additional temperature test equipment, and can complete multiple core performance tests of dry-type transformers in a single test. The equipment supports batch test presets for dry-type transformers, quickly switching test parameters for different types of dry-type transformers, adapting to batch detection needs of transformer manufacturers, and supports generating industry-standard dry-type transformer test reports.
Detailed specifications include: maximum output DC withstand voltage: 35kV; partial discharge detection sensitivity: ≤1pC; temperature rise load test capacity: 30kVA; temperature test accuracy: ±0.5℃; DC resistance test accuracy: ±0.2%; turns ratio test range: 1~10000; equipment weight: 650kg; equipment dimensions: 1600×1000×1400mm; support for docking with dry-type transformer temperature online monitoring system; operating environment temperature: 0℃~40℃; relative humidity: 30%~80%; standard dry-type transformer special test electrodes and cables.
It is mainly applicable to ex-factory quality inspection of dry-type transformers, preventive tests of dry-type transformers in substations, commissioning and inspection of new energy cabinet transformers and performance evaluation of repaired dry-type transformers by power maintenance companies. Typical usage scenarios include batch finished product testing of dry-type transformer manufacturers, acceptance inspection of dry-type transformers supporting urban rail transit, and annual operation and maintenance testing of dry-type transformers in data centers, meeting the exclusive detection needs of dry-type transformers.
