Shanghai DemEs Power Technology Helps Pingmei Shenma Tianyuan New Energy Build Power Physical & Chemical Testing Laboratory

Shanghai Demiks Power Technology Co., Ltd. has completed the delivery, on-site installation and commissioning of a batch of power physical, chemical and equipo de prueba de alto voltaje for Pingmei Shenma Group Tianyuan New Energy Co., Ltd., helping Tianyuan New Energy establish a standardized power equipment testing laboratory. The full equipment package includes a transformer oil chromatography analysis system, a complete set of power frequency withstand voltage test device and supporting gas generation equipment. The lab can carry out self-inspection of core items such as power insulation and oil physical & chemical properties for new energy power stations, ensuring the long-term safe and stable operation of new energy power equipment for photovoltaic and wind power projects.

1. Core Delivered Equipment List & Product Introduction

1.1 DSP-206A Transformer Oil Chromatograph (Main Analysis Unit)

As the core testing instrument of the laboratory, this unit is equipped with DSP-206A-QF hydrogen generator, DSP-206A-KF air generator and carrier gas cylinders.

Aplicación: Perform gas chromatography analysis on insulating oil of oil-filled electrical equipment such as power transformers and reactors. It detects dissolved gas components in oil including methane, ethane, ethylene, acetylene, hydrogen, carbon monoxide and carbon dioxide. By tracking changes in gas concentrations, technicians can predict latent internal faults of transformers in advance, such as local overheating, arc discharge and insulation moisture. It serves as a core tool for condition-based maintenance of oil-immersed power equipment.

Escenarios de aplicación: Periodic preventive tests, fault diagnosis and equipment access testing for substations, box-type transformers and main transformers at Tianyuan New Energy power stations.

1.2 Complete Power Frequency Withstand Voltage Test Device (Transformador de prueba + Intelligent Control Console)

This complete set consists of an intelligent numerical control console and oil-immersed transformador de prueba fitted with grading rings and high-voltage insulating cylinders. It is the primary high-voltage insulation withstand testing equipment.

Aplicación: Apply power frequency high voltage to insulating components of power equipment including high-voltage switchgears, instrument transformers, cables, insulators and transformer windings. It assesses insulation withstand capacity and identifies insulation defects, moisture or damage. The power frequency withstand voltage test is a mandatory test for factory acceptance, handover and preventive tests of electrical equipment.

Escenarios de aplicación: Withstand voltage handover tests and annual preventive tests for booster stations, box transformers, high-voltage cables and insulating tools in new energy power plants.

1.3 Supporting Constant Temperature Equipment

The matched constant-temperature device dedicated to chromatography provides stable temperature control for sample preprocessing and constant-temperature degassing of oil chromatography samples. It improves gas release efficiency from oil samples and guarantees repeatability and accuracy of chromatographic test data.

The whole system is integrated with computers and data acquisition software. Test data can be automatically collected, stored and used to generate test reports, complying with power industry standards and supporting routine testing operations in enterprise in-house laboratories.

2. Business Background of Tianyuan New Energy & Necessity of Building an In-house Testing Laboratory

Pingmei Shenma Group Tianyuan New Energy Co., Ltd. specializes in new energy operations and manages power generation assets including photovoltaic power stations and wind farms. Its power stations are equipped with a large number of oil-filled high-voltage electrical equipment such as box transformers, main transformers, high-voltage cables and switchgears.

Power equipment at new energy stations runs under harsh outdoor operating conditions with drastic day-night temperature shifts and variable ambient humidity. Equipment insulation tends to age and absorb moisture, which may lead to insulation degradation and internal discharge risks. Once faults occur, power generation will be interrupted, resulting in substantial economic losses.

Dissolved Gas Monitoring in Transformer Oil: Early internal transformer faults do not trigger immediate shutdowns but produce characteristic gases. Transformer oil chromatography analysis is the only testing method capable of detecting latent internal faults without power outages. It enables condition-based maintenance and prevents catastrophic accidents such as sudden explosions and power failures.

Prueba de tensión soportada a frecuencia industrial: A mandatory procedure for handover tests before equipment commissioning and annual preventive maintenance. It can detect hidden insulation defects and verify the insulation strength of high-voltage equipment to avoid breakdown and short-circuit after commissioning.

Before building its own lab, most tests had to be outsourced to third-party testing agencies. This brought obvious pain points: long testing cycles, high costs and inability to conduct rapid detection for on-site emergency faults. After adopting the full set of testing equipment from DEMIKS Power, Tianyuan New Energy can independently complete insulation withstand voltage tests of on-site high-voltage equipment and transformer oil chromatographic testing. It shortens testing cycles, realizes regular condition monitoring of station equipment, cuts outsourcing testing costs and enhances rapid fault diagnosis and response capacity. The lab meets the mandatory requirements of power safety codes for equipment operation, maintenance and testing for new energy power producers.
