Document Type and Number:
WIPO Patent Application WO/2008/154787
Kind Code:
A1
Abstract:
A defective arc protection breaker comprises a signal sampling module(3) provided
with a sampling unit and mounted inside an electric equipment, a microcomputer
control unit(2), a contact switch(1) and a current detecting module(4) mounted
on incoming line terminals of a power grid. The signal sampling module(3) sends
signal of the sampling circuit of a sampling unit(31) to the microcomputer control
unit(2) to process. The microcomputer control unit(2) controls on-off of the
