ENTERPRISE BRIEF INTRODUCTION

HKGD-601 Anti Islanding Device

PRODUCT OVERVIEW

The device is suitable for the protection,measurement and control of high And low voltage interval units of new energy power generation at various voltage levels,and has perfect protection,measurement,control and communication monitoring fundtions,providing a complete solution for the protection and control of new energy power generation systems, which can effectively ensure the safe and stable operation of high and low voltage power grids and plant power systems.

Together with other protection and automation equipment,and automation system,can be formed through communication interfaces.All devices can be installed centrally on the screen,or installed in the high and low voltage switchgear. At same time,it is widely used in distributed photovoltaic power stations,when the photovoltaic side or any side of the grid side loses power,the anti-island protection device will quickly issue a command to the grid-connected switch,let it trip,thereby Ensuring the life safety of maintenance personnel on both sides of the photovoltaic,The device has a loss of voltage tripping,detection with pressure automatic closing function,when the fault is lifted,both sides of the photovoltaic are in a normal state.

And the the lone bind protection device will detect the relevant signal.Automatically close the grid-connected switch to make it work normally,eliminatingthe tedium of manual grid-connection
