YN-1200 Island Protection Device

The Isolation Protection and Control Device is primarily applicable to small power supply systems for 35KV, 10KV and below electric photovoltaic power stations and wind power stations. In the event of an islanding phenomenon, it can act as a backup protection to quickly disconnect the distributed island power source. This protection device features low-frequency, high-frequency, sudden frequency change, low voltage, high voltage, reverse power, line voltage trip, voltage closure, and combined trip protection functions.

Product Features

When the islanding phenomenon occurs, immediately cut off the power supply to ensure the safety of equipment and maintenance personnel.

Ensure stable and reliable power supply: The island protection device can effectively prevent local overloads in the power grid, avoiding any impact on the overall stable operation of the grid, thereby guaranteeing the stability and reliability of power supply.

Prevent Fault Escalation: In the event of a local fault within the power grid, the anti-islanding protection device can quickly disconnect that section of the grid, preventing the fault from spreading and affecting the entire grid, thereby effectively reducing the losses caused by the fault.

Enhance safety: The anti-islanding protection device monitors the grid's operational status, promptly detecting and addressing potential issues, thereby increasing the grid's safety and ensuring the stable operation of the power system.

Independent sampling circuit and separate channel: The anti-islanding protection device features an independent sampling circuit and separate channel, ensuring monitoring accuracy and anti-saturation performance for protection, facilitating the deployment and withdrawal of protection.

Self-protection and Alternativeness: Each circuit breaker corresponds to an operational circuit with a breaker trip and close coil protection function, and can replace the protection of conventional relays, reducing maintenance.
