Protection circuit and equipment, i.e. tear-away when fault current reaches 30mA, safety is higher, and inductor is detached from device and surge
Electric current isolation, avoids by surge damage, better reliability and 18mm/P can accomplish 25kA (level-one) and 100kA (second level), body
Product is small, and through-current capacity is big, installation more easily electric leakage induction type SPD backup protection breaker.
(2) technical solution
A kind of electric leakage induction type SPD backup protection breaker of the utility model, including electric leakage induction type back-up protection are disconnected
Road device and surge protector, are equipped with actuating mechanism inside the described electric leakage induction type backup protection breaker, the actuating mechanism with
Induced current buckle releaser is connected, which is equipped with secondary winding, and the secondary winding is connected with magnet ring, on the magnet ring
Side is equipped with switch, and overcurrent is equipped with inside the surge protector and is released device, after power supply line first passes through electric leakage induction type SPD
Standby protective breaker is connected with surge protector SPD again, when the overcurrent of any phase in SPD device of releasing deteriorates
When, the electric current for flowing through this phase line just will increase, and when increasing to certain value, leak electricity induction type SPD backup protection breaker
In magnet ring will generate the variation of magnetic flux, secondary winding induces sufficiently large electric current, and induced current acts buckle releaser, from
And trigger action mechanism, switch separating brake is driven, to make to be detached from the slave circuit of the surge protector SPD safety deteriorated.
Further, the electric leakage induction type SPD backup protection breaker and surge protector SPD series connection and end
End ground connection.
Further, the electric leakage induction type SPD backup protection breaker primary path uses pure copper wire material.
Further, the electric leakage induction type SPD backup protection breaker 18mm/P can accomplish 25kA (level-one) and
100kA (second level).
(3) beneficial effect
Compared with the prior art, the utility model has the following beneficial effects: the utility model uses pure copper wire, instead
Short between seasonable, residual voltage is low, and better protection circuit and equipment, i.e. tear-away when fault current reaches 30mA, safety is higher,
Inductor is detached from device and surge current and completely cuts off, and avoids by surge damage, better reliability and 18mm/P can accomplish 25kA (one
Grade) and 100kA (second level), small in size, through-current capacity is big, and installation is more convenient.
