The APD series medium-voltage switchgear partial discharge monitoring device monitors partial discharge signals during the operation of electrical equipment through ultra high frequency (UHF)sensors, transient earth voltage (TEV)sensors, and acoustic emission (AE)sensors, thereby determining whether there are insulation risks inside medium-voltage electrical equipment and providing early warning.
Main Feature
l Collect the operation data of the switch cabinet, enabling centralized monitoring and management, and uploading the data to the monitoring system for the maintenance personnel to refer to.
l Achieve one-click sequential control conversion operations for the "operation - hot standby - cold standby - maintenance" four states in coordination with various devices.
l Unctions such as pre-prepared operation tickets, automatic execution of operation ticket sequences, and anti-misoperation verification.
l Lremote control functions for circuit breakers, pressure plates, and handles, and has anti-misoperation double verification.
l L2 Ethernet interfaces and 6 RS485 serial ports.
l Supports Mod Bus-RTU, Mod Bus-TCP protocols, and IEC60870-5-104 protocol.
l Supports a graphical interface and can simultaneously adjust about 200 inverter groups.
