JSJW three-phase recloser distribution automation
The three-phase automatic voltage regulator can quickly detect faults in the power system and make accurate judgments on these faults, thereby isolating the faulty equipment within a short period of time to ensure the normal operation of the system. The working principle of the recloser is based on Faraday's law of electromagnetic induction and Hall effect principle. When a fault occurs in the power system, the fault current will trigger the induction coil inside the recloser, forming an electromagnetic field, which causes the iron core to flip.
Automatic reclosing and fault isolation: It can monitor overcurrent, short circuit, grounding and other faults in three-phase lines in real time. When a fault is detected, it quickly trips to cut off the power supply, and then automatically performs multiple reclosures (usually 1-4 times) according to the preset program. If it is a transient fault (such as lightning strike flashover), power is restored after reclosure; if it is a permanent fault, it remains tripped and locked to avoid the expansion of the fault.
Adapted to the characteristics of three-phase power grids: Designed based on the symmetry of three-phase current and voltage, it can accurately identify asymmetric faults such as single-phase grounding and two-phase short circuit, ensuring the selectivity and reliability of the action, protecting the safety of three-phase lines and downstream equipment, and suitable for complex topological structures such as distribution line branches and ring networks.
Intelligent and autonomous operation: Equipped with a microprocessor, it supports setting of action parameters (such as the number of reclosures, time interval), and can work independently without relying on external control systems; some models have communication functions, which can be connected to the distribution automation system to achieve remote monitoring and parameter adjustment, reducing labor costs for maintenance.
It is widely used in medium and low voltage three-phase distribution networks, and is a key device for improving line power reliability and shortening fault outage time.
