OOPR DENSITY > Description These instruments are used to monitor SF6 gas density in sealed tanks. They are applied to provide a signal outputs when the density reaches the set value. At the same time, they reliably output SF6 gas density signal for remote monitoring. They are specifically designed for over 500KV EHV grade application field, adapting multi-level protection and full range of shielding measures to ensure the reliable operation of the products. > Application SF6 Gas Insulated Switchgear (GIS) SFe Insulated Circuit Breakers SFe Insulated Pole-Mounted Switch > Features 1. They adopt highly reliable protection circuit design, multi-level isolation and filtering technology, thus effectively inhibiting the intrusion of conductive interference. 2. They adopt the full-body shield design, stainless steel shielding shell, shielding junction box and military-grade shielding window glass, thus ensuring the ability of anti-electromagnetic radiation interference. 3. They are able to adopt the optic fiber communication backstage, thus avoiding data transmission link from electromagnetic interference. 4. The use of high-precision SF6 density algorithm ensures that the background monitoring data coincides with those field instructions. 5. They are fully compatible with ordinary SF6 remote products. They do not need other modifications in strong interference occasions. 6.The temperature compensation device ensures higher measurement accuracy. 7. Suitable for indoor or outdoor installation 8. Up to Four switch contacts can achieve overpressure alarm, dual alarm or double locking and many other solutions, ensuring the monitoring more secure and reliable SF6 Insulated Transformers SFe Insulated Mutual Inductor SFe Insulated Busbar Systems > Options 1.
