HKJL-606 Fault Decoding Protection Measurement & Control Device
PRODUCT OVERVIEW
The device is suitable for the protection measurement and control of interval units
of 110kv and below voltage levels,with perfect protection,measurement,
control,and communication monitoring functions,providing a complete solution for the protection and control of substations,power plants,high and low voltage power distribution and plant power systems,which can effectively ensure the safe and stable operation of high and low voltage power grids and plant power systems.Can and other protection,The automation equipment together forms the automation system through communication interfaces,it can be installed on a group screen or separately in a high and low voltage cabinet.
Fault delineation protection devices are used more often in hydropower and
Stable operation,large hydropower and thermal power such protective devices are required.When a power station is connected to the grid,it is used to complete the safe and accurate grid connection of the power station (that is,the pressure difference,angle difference,and frequency difference on both sides meet the requirements),When the grid connection is completed,the fault de-column starts to run its own function,detects the voltage and current problems of the grid-connected bus or line,and jumps off the grid-connected point switch after reaching the fixed value.So that the station is separated from the power grid,the delising function is completed,and the grid connection point switch is jumped.
