The Application of Reclosers and Sectionalizers in Distribution Network Automation

Four Fast 1. Selection of Reclosers and SectionalizersThe selection of reclosers and sectionalizers is crucial for achieving distribution network automation. Sectionalizers cooperate with the upstream circuit breakers on the power supply side. They automatically trip when three conditions are simultaneously met: the fault current exceeds its set - value, the line undervoltage current is less than 300 mA, and the set number of counts is reached. Reclosers are applied in indoor substations or on outdoor pol

What is the automatic recloser fault diagnosis technology?

Four Fast According to statistics, the vast majority of overhead line faults are "transient", with permanent faults generally accounting for less than 10%. Currently, for 10kV distribution network lines, the combined use of automatic reclosers and sectionalizers can quickly restore power supply after a transient fault and isolate the faulty line section in case of a permanent fault. It is necessary to monitor the operating status of the automatic reclosing controller to enhance its operational reliability
