Paglalarawan:
Ang device na RWB-300 digital microcomputer protections ay maaring gamitin sa small current small resistance grounding system ng 3kv at ibaba, na nagbibigay ng mga function tulad ng protection, control, communication, at monitoring. Ang device ay gumagamit ng ideya ng component programmable design upang bawasan ang maintenance workload at spare parts, na maaaring pumaligid sa mga pangangailangan ng iba't ibang aplikasyon, at ito ang pinakamahusay na substitute para sa traditional electromagnetic relay protection.
Pagpapakilala sa pangunahing function:
Pangunahing function ng protection relay: tatlong yugto ng phase-current protection, zero-sequence current protection, negative sequence current protection, inverse-time protection, overload component, reclosing, frequency protection, undervoltage/overvoltage protection, zero sequence phase overvoltage protection, motor start fast break protection, negative sequence overcurrent, at overheat protection.
Control functions: circuit-breaker control.
Monitoring Functions: primary currents para sa Phases at Zero sequence current, primary PT Voltage, Frequency, Binary Input/Output status, Trip circuit healthy/failure, Time and date, Fault records, Event records, Switching monitoring.
Communication functions: Gumagamit ng RS485 interface ng device na nagbibigay ng Modbus RTU Communication protocol link sa SCADA system; naka-enable ang Events\Faults at Measurands viewing, remote command execution, Time synchronizing, Viewing and Changing Settings.
Data Storage functions: Event Records, Fault Records, Measurands.
Remote signaling, remote measuring, at remote controlling function ay maaaring i-customize ang address.
