Advantages
Highly Intelligent and Automated Control
Equipped with Schneider Electric components and PLC intelligent control, the system supports both automatic and manual operation, real-time oil pressure monitoring, and human-machine interaction. This makes the transformer sealing test smarter and more versatile.
Convenient Construction with Cost and Efficiency Benefits
The compact, lightweight, and user-friendly design simplifies the construction process. It eliminates the need for large-scale construction machinery on-site, thereby reducing operational risks and significantly saving both labor and construction costs.
Comprehensive Safety Interlocks and Electrical Protection
The system features multiple interlocking safety protections (including liquid level-pressure interlocks, anti-backflow devices, and dry-run prevention). It also includes overload, phase loss, and phase sequence protection, along with emergency stop functions, strictly adhering to IEC/GB electrical safety standards.
Versatile Operating Modes and Precise Control
The equipment supports four operating modes: oil storage, circulation, constant pressure, and emptying. The oil pump motor utilizes frequency conversion technology and is equipped with a flowmeter, allowing for precise adjustment of the oil flow rate to meet actual needs.
Efficient and Stable Fluid Transfer System
High-quality oil pumps are used to ensure low operating noise and a long service life. Quick couplings are applied to the oil inlet and outlet ports for reliable sealing and fast operation. Additionally, the low flow rate design effectively prevents static electricity generation during oil transfer.
Reliable Automatic Liquid Level and Pressure Management
An automatic liquid level control system and an automatic pressure protection system are integrated to ensure high-performance equipment operation. These systems prevent adverse effects caused by misoperations and guarantee safety during oil injection and external replenishment.
Application
Transformer Manufacturing & Factory Testing: BBS Series transformer test bench Used for pre-shipment sealing inspections to ensure compliance with IEC/GB standards.
On-site Installation & Maintenance: Ideal for field testing after installation or repair, eliminating the need for heavy machinery and reducing operational risks.
Corrugated Tank Transformers: Specifically designed for sealing tests on corrugated (internal oil) type oil storage tanks.
Key Accessories Testing: Verifies the sealing integrity of critical components like Buchholz reliefs, pressure relief valves, and oil level indicators.
Routine O&M & Condition Assessment: Helps evaluate the remaining lifespan of aging seals in long-term operation, supporting predictive maintenance planning.
FAQ
Q: What is the primary application of this equipment?
A: The BBS series equipment is primarily used for transformer body sealing tests. It detects potential leaks by injecting oil or gas into the transformer tank and maintaining a constant pressure, ensuring the sealing performance meets the required standards.
Q: What operating modes does the equipment support?
A: The device features four main operating modes to meet various testing needs:
Oil Storage Mode: Transfers oil into the storage tank.
Circulation Mode: Circulates oil internally within the storage tank to eliminate air bubbles.
Constant Pressure Mode: Maintains a steady pressure to perform the sealing test on the transformer body.
Emptying Mode: Drains the oil out of the equipment after the test is completed.
Q:What are the features of the control system?
A: The equipment utilizes advanced PLC control technology with a touch screen for human-machine interaction. Operators can easily set parameters, select menus, and run self-checks via the screen. The system monitors the transformer's oil pressure in real-time and automatically stops oil injection to begin the pressure holding timer (typically 24 hours) once the set pressure is reached.
Q: What are the advantages over traditional methods?
A: This equipment is compact, lightweight, and mobile (equipped with casters). It significantly reduces labor intensity and simplifies the construction process compared to traditional methods. Additionally, it lowers labor and construction costs while featuring high-quality vacuum and oil pumps for low-noise, high-efficiency operation.
Q: How is safety ensured during operation?
A: The device is designed with multiple safety mechanisms. It includes interlocking safety protections to prevent adverse effects from misoperation (e.g., the oil discharge system is interlocked with liquid level pressure). The oil pump motor has an overload shutdown device, and the electrical system complies with IEC/GB standards, featuring phase sequence and phase loss protection.
Q: What are the key technical parameters?
A: BBS Series transformer test bench based on the technical parameter list (taking the BBS-I model as an example):
Flow Rate: 0-5 L/min (Adjustable)
Working Vacuum Degree: -0.04 ~ -0.07 Mpa
Working Pressure: 0-0.55 Mpa
Power Supply: AC220V/50Hz
