As a new type of electrical protector, auto reclosing circuit breaker has been widely used in power supply industry. For example, some railway, airport, traffic lights and other automatic power supply have gradually begun to use auto reclosing circuit breaker. Auto reclosing circuit breaker can be widely used so quickly because it has air circuit breaker and leakage circuit breaker. All the functions of these two circuit breaks also have the function of detecting and protecting the electric energy. As long as the electric energy in the circuit breaks down, the automatic reclosing circuit breaker can be automatically switched off at the first time without special supervision. Only when the fault is completely removed can the power supply be switched on. The whole process is automatic, which greatly reduces the worker's burden.
Of course, in order to achieve the above mentioned automatic operation, auto reclosing circuit breaker should abide by some basic operations in use, according to the instructions for use. Here we will explain some matters needing attention in the use of auto reclosing circuit breaker.

At first, we need to connect the device before using automatic reclosing circuit breaker. After connecting the output end of the product with the device, we can check carefully and confirm that the circuit breaker is correct before closing the circuit breaker for the next electrical test.
After we turn on the power supply for 3 seconds, the automatic reclosing circuit breaker automatically closes, and the output indicator lights shine. This shows that the automatic reclosing circuit breaker is normal in this respect. It can confirm that the power has been turned on. Press the experimental button on the automatic reclosing circuit breaker, cut off the circuit and cause circuit failure. See whether the automatic reclosing circuit breaker will automatically close and give an alarm. If there is no such change, it means that this auto reclosing circuit breaker is not qualified and needs to be manufactured again. If it happens normally, we will see if the auto reclosing circuit breaker will be automatically closed after the next 30 seconds.
The general automatic reclosing circuit breaker is designed as the first 30 seconds automatic closing. If the circuit is still faulty, it will be reclosed until the second closing takes place after 30 minutes. Then if the circuit has not been restored to normal, it will be the third closing after 60 minutes. If the fault still exists, the self-locking operation will be carried out after the trip. As a result, we can't do automatic closing. We can only wait for us to remove the fault and turn on the automatic reclosing circuit breaker to restore the power supply. If all the experiments are normal, it shows that the auto reclosing circuit breaker is qualified for closing and closing in case of failure.
Of course, if we remove the fault within 30 seconds after the first circuit cut-off and the auto reclosing circuit breaker closes automatically, the number of faults will be cleared if the auto reclosing circuit breaker recloses successfully, which can make the auto reclosing circuit breaker more flexible in use, very convenient in real life, and do not need too many operators to do it. Maintenance.
In addition, when we use the auto reclosing circuit breaker, we should also understand what the five indicators above the auto reclosing circuit breaker refer to. The five indicators are running, voltage, leakage, short circuit, output from the left. Here we will discuss the difference of the five indicators of the auto reclosing circuit breaker in the process of using the auto reclosing circuit breaker in turn.
Firstly, the running indicator is that the auto reclosing circuit breaker will flicker frequently when it is in normal operation.
1. Voltage, indicating that the indicator has entered the overvoltage protection when it is on for a long time, and when the voltage indicator flashes, it means entering the undervoltage protection. That is to say, once the voltage indicator lights up, the automatic reclosing circuit breaker is to trip and cut off the power supply.
2&3. Leakage, short circuit, is the same, as long as the light on the auto reclosing circuit breaker has leakage and short circuit fault, need to be repaired in time.
4. Output means whether the automatic reclosing circuit breaker is on, green means that the automatic reclosing circuit breaker is on normally, and extinguishing means that the automatic reclosing circuit breaker is off.

This is some instructions for the use of auto reclosing circuit breaker. I hope it will be helpful to you.
