Pangangalagaang aparato ng digital na mikrokompyuter na may device na RWB-300

Paglalarawan：

Ang device na RWB-300 digital microcomputer protection ay applicable sa small current small resistance grounding system ng 3kv at ibaba, na nag-integrate ng proteksyon, kontrol, komunikasyon, monitoring, at iba pang mga function. Ang device ay gumagamit ng ideya ng component programmable design upang mabawasan ang maintenance workload at spare parts, kaya ito ay maaaring mapayabong na sumunod sa mga pangangailangan ng iba't ibang aplikasyon, at ito ang pinakamagandang substitute para sa traditional electromagnetic relay protection.

Pagpapakilala sa pangunahing function：

• Pangunahing relay functions: 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, overheat protection.

• Kontrol 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: Gamit ang RS485 interface ng device passing Modbus RTU Communication protocol link to SCADA system; realizable Events\Faults at Measurands viewing, executing remote command, Time synchronizing, Viewing at Changing Settings

• Data Storage functions: Event Records, Fault Records, Measurands.

• Remote signaling, remote measuring, remote controlling function can be customized address.
