Photovoltaic automatic reclosing circuit breaker--solar automatic reclosing breaker-- has overload, short circuit and under-voltage protection function, can protect line and power equipment from damage, at the same time, photovoltaic automatic reclosing circuit breaker can provide indirect contact protection for people.It can also provide protection for the long-existing grounding fault that cannot be detected by overcurrent protection and may cause fire hazard.
Most overhead line faults are transient in nature, such as an insulator or a spark gap flashover or a temporary contact with foreign objects or animals.
The majority of these faults is due to weather conditions and typically results from thunderstorms, heavy wind or extreme snow and ice conditions together with high temperature changes.
If these faults are not self-clearing, they result in trippedof the circuit breaker to isolate the fault spot, and they do not recur when closing the circuit breaker, that is ,re-energizing the feeder after a short-time delay.
For the clearing of this type of faults,automatic reclosing(AR)is employed.
After the occurrence of a fault, the circuit breaker will be tripped by the protection functionality of the protected feeder followed by an automatic reclosing or an AR(circuit recloser)-shot, which is a function where the circuit breaker is automatically reclosed after a set time delay.
PV Auto Reclosing--solar automatic reclosing breaker-- greatly improves the reliability of power supply and reduces the number of power outages, especially for single-circuit lines with one-side power supply.
