1. Project Overview

The Automatic Distribution Transformer Test System delivered by Nanke Electric to Jiangsu Shuangxin Transformer Co., Ltd. has been officially put into operation.

Jiangsu Shuangxin Transformer Co., Ltd. is a specialized intelligent manufacturing base for high-efficiency, energy-saving transformers rated up to 220 kV and integrated energy storage converter units. The company focuses on new power systems and the renewable energy distribution network sector. Its main products include high-efficiency oil-immersed and dry-type distribution transformers rated up to 35 kV, 110–220 kV power transformers, integrated energy storage converter units, and supporting power transmission and distribution equipment. To meet the factory testing requirements for transformers, Nanke Electric delivered an Automatic Distribution Transformer Test System for the project, covering testing of both oil-immersed and dry-type transformers.

4. Project Highlights

1. Compatibility with Multiple Transformer Types

The project includes both oil-immersed and dry-type transformer test stations. The system is compatible with testing different types of transformers, covering 10 kV and 35 kV voltage levels and meeting the testing requirements of oil-immersed transformers from 30 kVA to 10000 kVA and dry-type transformers from 30 kVA to 6300 kVA.

2. Automated Testing, Reduced Repetitive Wiring, and Improved Testing Efficiency

The project adopts an Automatic Distribution Transformer Test System. After transformer parameters are registered, operators can click “Automatic Test Start” and view the test interface through the control console, enabling automated control of the testing process and real-time monitoring of test data. The automated testing process reduces repetitive wiring between different test items and manual operations, simplifies the testing process, improves transformer testing efficiency, and allows test reports to be customized according to customer requirements.

3. Integrated Testing Functions, Reduced Labor Costs

The system integrates multiple transformer testing functions. Through the automated testing process, it reduces manual operations, data recording, and repetitive work, thereby reducing the labor input required for testing and related labor costs.

4. Professional Configuration, Balancing Performance and Cost Efficiency

The system is equipped with professional instruments such as a digital power analyzer and a multi-channel digital comprehensive partial discharge analyzer according to the project's testing requirements. While meeting the requirements of multiple transformer testing items, the configuration also takes into account actual application needs and equipment requirements.
