Advantages
Compact and Portable Design
Bubble Free Online Oil Refilling Machines feature a small footprint and lightweight construction, mounted on a specialized lifting platform with casters. This design facilitates easy loading, unloading, and mobility across different job sites.
High-Efficiency Dehydration & Degassing
It utilizes a unique large-area three-dimensional flash evaporation technology. This system rapidly separates moisture and gases from the oil, ensuring high purification efficiency.
Precision Filtration with Auto-Detection
Equipped with a sophisticated filtration system capable of effectively removing mechanical impurities. Crucially, it includes an automatic detection function for filter contamination, alerting operators when maintenance is needed.
Comprehensive Safety Interlocks
The machine ensures operational safety through a complete interlock system connecting the oil discharge, vacuum, and heating systems. It also features protection against electric leakage, overload, phase loss, and incorrect phase sequence to prevent motor damage and accidents.
Stable Heating & Low Noise Operation
The heating system uses an optimized pipeline design to ensure uniform oil temperature stability. Additionally, the use of high-quality pumps results in low noise levels and a long service life.
Advanced Control & Live-Line Capability
The equipment supports online operation (live-line oil processing) to minimize power outage losses. It offers flexible control options, including simple relay control or advanced PLC intelligent control for automatic or manual operation.
Application
Bubble Free Online Oil Refilling Machines are widely applied in power plants, power stations, power enterprises, power transmission and transformation, metallurgy, petrochemical, machinery, transportation, railway and other industries.
FAQ
Q: What is the primary application of the XJY Bubble-free Online Oil Refilling Machine?
A: It is primarily used for online, bubble-free oil refilling and purification in oil-immersed transformers across power plants, substations, metallurgy, petrochemical, and transportation industries. It ensures uninterrupted transformer operation by maintaining optimal oil levels without causing dielectric breakdown or safety hazards.
Q: How does the machine prevent bubbles during oil refilling?
A: It employs a unique large-area 3D flash evaporation system combined with precision filtration and vacuum degassing. This technology rapidly removes moisture and gases from the oil before refilling, ensuring no air bubbles are introduced into the transformer tank during operation.
Q:Can this machine operate while the transformer is energized?
A: Yes, it supports live-line, online oil refilling without shutting down the transformer. This feature minimizes power outages and economic losses, making it ideal for critical infrastructure where continuous operation is mandatory.
Q:What safety features are included to protect operators and equipment?
A: The machine includes comprehensive interlock protection between oil discharge, vacuum, and heating systems; automatic shutdown for phase loss, overload, or leakage; and a built-in anti-static device on the oil outlet pipe. It also features PLC intelligent control for automatic or manual operation with real-time status monitoring.
Q: How is the filtration system maintained, and does it have self-diagnostic capabilities?
A: It uses high-quality filter cartridges with multi-stage precision filtration and includes an automatic contamination detection system. When filters reach saturation, the machine triggers a stop signal and displays a replacement indicator, ensuring consistent filtration performance without manual guesswork.
Q: What are the key technical specifications for flow rate and vacuum level?
A: Bubble Free Online Oil Refilling Machines offer a flow rate of 10–20 L/min and achieves a working vacuum degree of -0.08 to -0.098 MPa. It operates at 380V/50Hz (3-phase 4-wire) and has a total power consumption of 8 kW, making it suitable for both small-scale maintenance and large industrial applications.
