Overview

Low-voltage anti-isolated island protection device  is a 380V voltage level distributed power generation launched after a large number of market research, configuration scheme demonstration on the basis of the company's accumulation of years of research and development, production of digital protection measurement and control device, its function
setting according to the national distributed power grid related standards and specifications. Integrated switch equipment,
protection, measurement and control, communication and other functions required by the grid connection of distributed power supply, meet the requirements of isolated island detection of distributed power access, automatic safety grid connection, protection and safety isolation, and the occasions where the self-generated surplus power can not be connected to the Internet.
The device realizes the integration and simplification of the equipment needed for the network connection of distributed power supply, and realizes the plug and play of distributed power supply connecting to the distribution network. Main Function of Anti-Island Protective Device 1. When the power grid side loses power, maintenance personnel need to repair it. At this time The local side is still in the normal power generation state, and the anti-island protection device will be merged The network switch sends out an order to make it trip, thus ensuring the photovoltaic power supply and power supply. Life safety of side maintenance personnel. 

2. When the frequency, voltage or When overloaded, the anti-island protection device will also quickly send out to the grid-connected switch Order, let it trip, so that the main equipment on both sides is well guaranteed not to be injured Harmfulness to avoid further expansion of accidents. 3. When the fault is lifted, both sides of the photovoltaic are in a normal state. At this time, anti-isolation The island protection device will detect the relevant signal and automatically close the grid-connected switch Let it work normally, save the tedious manual grid connection Brake, check pressure automatic closing function, etc.
