General

 

PV automatic reclosing mini circuit breaker for AC 50Hz, rated working voltage to 400V, rated current to 80A,  the line for long-distance automatic closing, sub-gate control or automatic signal control closing gate, at the same time On the line from the role of overload and short circuit protection, you can also support the use of voltage off the use of power off the sub-gate, call automatic closing function. At present, widely used in photovoltaic grid-connected AC distribution box, and personnel difficult to close the occasion, maintenance personnel can not be in place in time, unattended occasions, power supply continuity requirements of the higher occasions.

(1) During normal operation, the automatic reclosing device shall be operated when the circuit breaker is tripped by relay protection action or other reasons.

(2) Automatic reclosing should not be started when the circuit breaker is disconnected by manual operation or by remote control.

(3) Relay protection action After the removal of the fault, automatic reclosing device should be issued as soon as possible reclosing pulse.

(4) automatic reclosing device action should meet the pre-set requirements.

(5) The automatic reclosing device shall be capable of accelerating the relay protection before or after reclosing in order to accelerate the removal of the fault.

(6) in the bilateral power lines to achieve reclosing, the reclosing should meet the same period closing conditions.

(7) When the circuit breaker is in an abnormal state and does not allow reclosing, the automatic reclosing device should be latched.
