SERGI CONSERVATOR SHUTTER Type TL
Essential fire protection for transformer safety
When transformers explode after short-circuits, the SERGI CONSERVATOR SHUTTER Type TL isolates the conservator when an abnormal flow is detected for preventing the conservator oil to feed the consecutive oil fire.​
The SERGI CONSERVATOR SHUTTER Type TL is a flow sensitive shutter valve:​
- Rapid Isolation: Quickly and effectively isolates the oil in the conservator tank when abnormally high oil flow is detected. This can be caused by a ruptured transformer tank, an open valve, a significant pipe leak, or a damaged radiator.​
- Bidirectional Flow: Allows oil to flow in both directions when transformers are in normal operation with oil temperature and volume variations due to transformer power or outside temperature changes.​
Characteristics of the SERGI CONSERVATOR SHUTTER Type TL:​
- Market-Exclusive Testing: The only shutter on the market tested under transformer insulation rupture conditions. Live test certificates are available upon request.​
- Self-Contained and Mechanical: Fully mechanical design requires no external power source.​
- Commissioning-Free: Ready to operate immediately without any need for commissioning settings.
- Integrated Alarm System: Equipped with a magnetic switch that sends an alarm to the plant control room when the TL closes.​
The SERGI CONSERVATOR SHUTTER Type TL use is frequently recommended on electric utilities in earthquake and hurricane-prone areas, where movement often leads to ruptured or leaking transformer conservator pipes.​
