Buchholz Relay type eBR |
| COMEM’s eBR is equipped with a digital interface for easy connection to the smart grid and it can be integrated into a single system via a central control unit.The eBR can work in standalone mode or integrated into a single system, which is compatible with the most common international communication protocol standards. COMEM’s eBR provides improved monitoring of the gas inside the Buchholz relay and the oil flow speed. |
| Construction |
| The new COMEM Buchholz relay with analog and digital output is an assembly of high strength components which ensures a perfect oil seal. The main body of the relay is fitted with tempered glassinspection windows with graduated scale markings in cubic centimeters to indicate the internal volume. The oil drain plug is located at the bottom of the main body. The top cover hold the frame which contains the moving parts of the relay. The two floats and their associated reed switches reed and magnets, two calibrated flow valves. The cover also: • A gas discharge valve with G1/8" in male thread with protective cap • A valve for pneumatically testing the alarm and insulation circuits, with protective cap • A push rod for mechanical verification of the reed switch with protective cap • A terminal box |
| Advantages |
| • Continuous gas monitoring of the gas inside the Buchholz relay; • Settable alarm and trip thresholds for the oil flow speed; • Double oil flow threshold (alarm and trip); • Thanks to the dedicated and independent contacts for both floats and flow vane, in case of failure, there is a clear identification of the main cause; • Contact output for the gas discharge valve opening; • Analog Output and Digital Control. |
