Title:
CIRCUIT INTERRUPTER AND CURRENT TRANSFORMER THEREOF, AND HOUSEHOLD APPLIANCE INCLUDING CIRCUIT INTERRUPTER
Document Type and Number:
WIPO Patent Application WO/2019/056812
Kind Code:
A1
Abstract:
Disclosed are a circuit interrupter and a current transformer thereof, and a household appliance including the circuit interrupter. The current transformer comprises: a housing (3), a zero-sequence mutual coil (2), a current mutual coil (5), a phase line conductor (6) and a neutral line conductor (8), wherein the zero-sequence mutual coil and the current mutual coil are accommodated in the housing in a mutually superposed manner; a sensing portion (65) of the phase line conductor simultaneously passes through the zero-sequence mutual coil and the current mutual coil, so that the zero-sequence mutual coil and the current mutual coil share the phase line conductor; and a sensing portion of the neutral line conductor passes through the zero-sequence mutual coil. According to the solution, two transformer housings are changed into one, thereby reducing one transformer housing and saving on safety space, on a PCB, between housings of a current transformer and a zero-sequence transformer, so that the area occupied by the transformers on the PCB is reduced by more than half.
