BF50/10 реле на Бухолц - Газовата защита на трансформатори
Газовата защита на трансформатори е позната в практиката като Бухолц реле. При някои повреди в трансформаторите често протичат малки токове, на които диференциалната и токовата защита не реагират.
The Buchholz relay is an important protection and monitoring device for insulating liquid filled-transformers with conservators and choke coils. It also allows separate monitoring of oil-filled bushings or cable terminal boxes.
It is mounted in the cooling cycle of the appliance to be protected and responds to faults such as gas generation, loss of insulating liquid and excessively high flow rates of the latter.
Buchholz relays are available in a number of types which comply with norms and standards and meet special customer requirements. The type of relay to be used depends on the nominal rating and construction features of the appliance to be protected.
EMB Buchholz relays comply with DIN EN 50216-2 and are known for their easy operation, high reliability and extremely long life"
