FAQ
Q:What is the primary function of the ZJJ-I Series Machine?
A: The ZJJ-I Series is an Online Vacuum Oil Filling Machine (also known as a Bushing Oil Machine). Its primary function is to perform automatic vacuum evacuation and on-load oil filling for Current Transformers (CT) and Potential Transformers (PT). It is specifically designed to adjust oil levels after periodic sampling or testing without needing to shut down the equipment.
Q: How does this machine improve upon traditional manual oil filling methods?
A: Traditional manual methods often introduce air bubbles into the CT/PT coils or cause "illusory oil levels" due to residual air, which can be dangerous. The ZJJ-I machine solves this by using a high-efficiency vacuum pump to ensure a bubble-free injection process. This guarantees accurate oil levels and prevents air absorption by the internal coils, ensuring the safety and reliability of the transformer.
Q:Can the ZJJ-I machine operate while the transformer is still running?
A: Yes, absolutely. As an "Online" oil filling machine, it is designed to operate while the CTs and PTs are energized and in service. There is no need to stop the PT/CT during the oil filling process, which significantly improves maintenance efficiency and grid reliability.
Q:What are the key technical specifications of this unit?
A: According to the technical parameter list:
Oil Filling Capacity: 0.5-2 L/min (Adjustable)
Working Vacuum: ≤ -0.075 MPa
Filtration Precision: ≤ 1μm (β₁≥1000)
Total Power: 0.8 Kw
Noise Level: 60 dB(A)
Weight: 35 kg
Q:Is the machine portable and easy to use in substations?
A: Yes. The machine features a compact design (Dimensions: 600×350×375 mm) and is lightweight (35 kg), making it highly portable for field work in various power substations. It is equipped with a handle for easy transport and offers both manual and fully automatic control modes for convenient operation.
Q: What safety and protection features are included?
A: ZJJ-I Series Online Vacuum Oil Filling Machine is equipped with several safety mechanisms to ensure reliable operation:
System Over-pressure Protection: Prevents damage from excessive pressure.
Automatic Constant Temperature Heating & Dehydration: Ensures the oil is treated safely without overheating.
High-quality Filters: Ensures the oil cleanliness meets strict standards (≤1μm).
