Product Description

Three Phase Recloser Description

The three-phase recloser is an intelligent device. It can automatically detect the current passing through the main circuit of the recloser. Once it determines that it is a fault current, it will automatically cut off the fault current for a certain period of time according to inverse-time protection, and can perform multiple automatic reclosures as required to restore power supply to the line.

Why use three-phase reclosers

The recloser provides an important foundation for achieving high safety and reliability of medium-voltage overhead lines outdoors. It is regarded as an important power equipment by power companies all over the world for realizing feeder automation. It detects and interrupts fault currents, and automatically resumes service after a temporary power outage. Transient faults include transient circuit abnormalities caused by lightning strikes, fallen branches, wind-blown wires, bird contact, etc., but these can be automatically eliminated. 
The intelligent distribution recloser is a flexible outdoor vacuum switchgear that can be installed on utility poles or on structures. When a temporary line fault occurs, it can trip and reclose multiple times (usually set to 3 to 4 times). If the fault is permanent, the recloser will lock after a preset number of reclosures, isolating the faulty components from the main components of the system to prevent the expansion of the fault area. 
The overlap device saves a great deal of time and money in power operation and maintenance. It can minimize the need for staff to go to the site for inspection and maintenance, minimize the area affected by power outages, help staff quickly locate the problem and restore power supply. It ensures stable power supply for residences, businesses, industries and public facilities, and avoids significant losses caused by frequent power outages. 
It can adapt to every application field and meet all the requirements for outdoor use. It combines cutting-edge technology with high-quality engineering expertise to provide the best solutions, leading the medium-voltage power grid towards digitalization and intelligence. 
The pole-mounted recloser is a high-performance distribution switch. In coastal environments with high air salinity, high humidity, severe pollution and a large number of birds, its advantages are more evident in ensuring the safe operation of the equipment.
