HSR361E Photovoltaic Box Transformer Protection and Monitoring Device
Scope of Application
HSR361E PV Box-type Substation Protection and Monitoring Device is a highly intelligent product independently developed by our company, mainly targeting the characteristics of PV grid-connected power generation and customers' extensive requirements for box-type substation protection, measurement, control and communication. The device integrates a communication management unit, optical fiber ring network switch and complete box-type substation protection and monitoring functions. It is responsible for collecting data from box-type substations, combiner boxes, inverters and other equipment, and then reliably transmitting the data to the booster station monitoring system via self-healing Ethernet/optical fiber ring network, realizing remote monitoring of PV power generation units by the booster station, so as to meet the requirements of remote monitoring and intelligent management of PV power stations.
