RTQC-60 SF6 Gas Vacuumizing Device

The RTQC-60 vacuumizing device is mainly used for vacuumizing and vacuum measurement during installation, operation, and maintenance of porcelain-clad SF6 circuit breakers, transformers, and other SF6 electrical equipment. The RTQC-60 is a compact SF6 gas charging and vacuumizing device. The entire charging and vacuumizing device is mounted on a very sturdy metal cart frame, allowing it to move freely even on gravel roads.

This device complies with the DL/T662-1999 standard "Sulfur Hexafluoride Charging and Recovery Device". It consists of a vacuum pump, pointer vacuum gauge, regulating valve, gas pipeline, and necessary valves and instrument control components for maintaining SF6 circuit breakers. It has the following main functions:

1. Vacuumizing and vacuum measurement for SF6 electrical equipment;

2. Charging SF6 electrical equipment.

 

1. Keep the device and its surrounding environment clean and dry at all times.

2. Regularly check the vacuum pump oil level, keeping it at the center of the oil gauge. For new pumps, it is recommended to change the oil after 100 hours of operation, and thereafter every 500-1000 hours. (The common oil grades for vacuum pumps are SY1634-701, or HJ-45, HJ-50. It is recommended to use PRO-100 high-speed vacuum pump oil as the lubricant.)

3. Over time, the vacuum degree may gradually decrease due to contamination of the pump oil with condensable gases, oil cracking and deterioration, and aging of rubber parts. This can be resolved by changing the oil or replacing rubber parts.
