Automatic Circuit Recloser (ACR) is an intellectual protective device capable of interrupting fault current and which purpose is to increase distribution system reliability. Their function is to automatically disconnect a section of feeder in the event of fault, such as a short circuit. After a certain period of time, the recloser makes a specified number of attempts to re-energize the line to restore power supply to consumers.
Recloser is an automatic high-voltage switchgear, which can be divided into three-phase recloser and single-phase recloser. Used in overhead power distribution networks to detect and interrupt transient faults. When the circuit fails (such as a short circuit), the power is cut off to protect the circuit from damage and ensure the stability of the power grid system. At the same time, the operation status of the recloser can also be controlled and monitored through the mobile phone and SCADA system.
Automatic Circuit Recloser adopts the most advanced solid insulation technology in the world, and deeply integrates the voltage sensor, current sensor, zero sequence current sensor, vacuum interrupter, etc. with the main circuit inside the insulation pole, which is a fusion of integrated solid insulation vacuum circuit recloser.
Recloser can be used with intelligent terminals to meet the requirements of reclosers, automatic sectioning devices, contact switches and user boundary switches on distribution network lines. At the same time, it can also be connected to the central master station through GPRS, optical fiber, Ethernet and other communication methods to form a distribution network feeder automation.
When the line is short-circuited, the recloser will automatically cut off the power supply, after a period of time (return to the original state) and automatically closes. If the line fault is not cleared, the recloser will continue to open the line, and after a period of time, it will automatically close. If the fault is permanent, after 3 repetitions, the recloser will be locked out. Electricity personnel are then required to perform on-site troubleshooting to repair the line to supply power.
According to the number of phase, it can be divided into: three-phase recloser and single-phase recloser
Single-phase reclosers are used to protect single-phase lines such as branches or taps of a three-phase feeder. When one of the lines fails, the other two phases can work normally.
Three-phase reclosers are used on three-phase circuits to improve system reliability.
According to the driving method, it can be divided into: the spring operation mechanism type and the permanent magnet mechanism type
And can choose to work with the recloser controller(FTU) to achieve the function of remote control. The recloser controller has the ability to sense overcurrent, select timed operation, time trip and recloser functions, and eventually lock out. At the same time, it can be controlled and monitored through mobile phone and SCADA system. View event records (such as power (A, W, VAR), voltage (V) or frequency (f) values.) from your mobile phone to easily troubleshoot line faults.
It can save a lot of time and cost for power companies, reduce the number of on-site operations of operation and maintenance personnel, quickly restore power supply, and avoid changes caused by frequent power outages.
