Power plant protection

The auxiliary class protection device refers to some unusual protection devices with auxiliary function,the main products are 961 communication management control device, 962 spare automatic inlet wire input protection and control device, 963 spare automatic inlet wire input protection and control device, 964 capacitor automatic feeding cutting protection and control device, 965 busbar Pt protection and control device, 966 bus Pt parallel protection and control device, 966J busbar Pt parallel protection and control device, 967 low pressure reducing load protection measurement and control device, 968 low cycle reducing load protection measurement and control device, 969 voltage reactive power automatic switching protection and control device.Most of these protection devices are used in the national network project and some very important projects,one of the few can produce these productive protection in domestic manufacturers,This kind of protective device produced by us has been used in many important projects both in domestic and abroad, its high cost performance and perfect protection function have won the Unanimous praise
  • 1208 automatic synchronization device

    1208 automatic synchronization device

    The 1208 microcomputer automatic synchronization device is applicable to various types of hydraulic power plant, thermal power plant, also suitable for substation, it can fully meet the needs of grid connected automatic of power plant and substation ,the 1208 microcomputer automatic synchronization device use frequency tracking AC sampling technology, continuous monitoring of voltage, and frequency of the system and generator, according to the frequency difference, pressure difference created a narrow pulse adjusting different frequency difference, until the pressure difference can meet the requirements.

  • 9690D Anti islanding protection relay

    9690D Anti islanding protection relay

    The 9690D photovoltaic anti islanding protection relay is mainly suitable for 110KV, 66KV, 35KV, 10KV and low voltage 380V photovoltaic power station small power grid connected power supply system,In the occurrence of the phenomenon of island, it can quickly disconnected grid connected switch, so ensure the safety of the entire power plant and related maintenance personnel.The anti islanding protection relay has the functions of over voltage, low voltage, high frequency, low frequency, reverse power, Peripheral switches trip together, frequency mutation and other protection.it is a high performance, cost-effective PV power plant anti island protection relay
