Recently, the high-voltage capacitor vacuum pressure oil impregnation equipment project undertaken by our company completed its final commissioning at the customer's site. It successfully passed the acceptance inspection by the customer's expert team and has been officially delivered for operation. The achievement of this significant milestone not only validates our company's profound strength in the fields of high-end fluid processing and vacuum applications but also adds a brilliant chapter to our track record in the power electronics manufacturing equipment industry.
The vacuum pressure oil impregnation equipment delivered this time is core process equipment specifically used for manufacturing high-voltage power capacitors and energy storage capacitors. This equipment requires a high-vacuum environment to perform strict drying, degassing, and pressure impregnation on the capacitor elements, ensuring low dielectric loss, high insulation performance, and a long service life for the capacitors.
As a leading domestic power equipment manufacturer, the customer set extremely high technical specifications regarding vacuum pumping speed, ultimate vacuum level, temperature uniformity, and process traceability. Facing complex process flows and a tight delivery schedule, our project team rose to the challenge and designated this as a key project.
The delivered equipment achieved multiple technological breakthroughs during its design and manufacturing process:
Superior Vacuum and Pressure Stability: The equipment is equipped with high-performance vacuum units. Combined with our unique anti-backstreaming and sealing structure design, it ensures long-term vacuum retention capability, fully meeting the deep impregnation requirements of metallized film capacitors.
Fully Automatic Closed-Loop Control System: Featuring an industrial intelligent control software, it automates the entire process from evacuation, heating, oil filling, pressurization, to oil return. The system possesses historical data traceability functionality, capable of recording and exporting process curves for each batch of products in real-time, truly achieving "transparency" and "standardization" in the manufacturing process.
Energy Saving and Safety Assurance: The equipment utilizes an efficient thermal oil circulation heating system and multi-layer thermal insulation structure, significantly reducing production energy consumption. Simultaneously, it integrates multiple pressure protection mechanisms, liquid level monitoring, and emergency pressure relief devices, ensuring personnel and equipment safety under high-pressure operating conditions.
During the on-site installation and commissioning, our engineering team overcame challenges such as extensive on-site cross-operations and spatial constraints, demonstrating a high level of professionalism. At the delivery site, the customer's technical team highly praised the equipment's operational stability, user-friendliness, and ease of maintenance.
The successful delivery of this project not only meets the urgent needs of the customer's capacity expansion but also serves as a concentrated manifestation of our company's technological accumulation in the field of capacitor manufacturing equipment.
