The HSR361E photovoltaic box-type transformer protection and monitoring device is a highly intelligent product independently developed by our company in response to the characteristics of photovoltaic grid-connected power generation and the extensive requirements of customers for protection, measurement and control, as well as communication of box-type transformers. This device integrates a communication management unit, an optical fiber ring network switch, and complete protection and measurement control functions of box-type transformers.
The HSR362E box-type transformer protection and control device is a highly intelligent product independently developed by our company in response to the characteristics of photovoltaic grid-connected power generation and wind farms, as well as the extensive requirements of customers for transformer protection, measurement and control, and communication. This device integrates a communication management unit, an optical fiber ring network switch, and complete protection and control functions for the transformer box, responsible for collecting data information from the transformer box and other equipment, and then transmitting it reliably to the substation monitoring system via self-healing Ethernet/fiber ring network, enabling remote monitoring of the transformer box by the substation, thus meeting the requirements of remote monitoring and intelligent management of the power station.
The HSR363E islanding protection device is applicable to low-frequency, high-frequency, low-voltage, overvoltage, zero-sequence overvoltage separation protection, and three-phase inter-phase overcurrent protection in substations or power plants of various voltage levels. This device can be installed locally in the switch cabinet or grouped in a centralized panel, and it provides communication interfaces. It can also be integrated with other protections and automation equipment through communication interfaces to form an automation system.
The HSR360E distributed power grid connection interface device is mainly used in distributed photovoltaic power stations to achieve the collection and protection, operation and control of distributed photovoltaic power generation information. This device is generally installed at the 10kV photovoltaic connection point.
