This moulded case circuit breaker's theory of operation with electric leakage prompt facility:
when the leakage detection circuit breaker is used, the protective shell 201 and the breaker body 1 are in a closed state, the operation condition of the breaker body 1 is monitored in real time through the leakage detection chip 301, after the leakage detection chip 301 monitors the leakage condition, a signal is transmitted to the PLC control board 302 in time, the buzzer 306 and the alarm lamp 308 are enabled to sound and light through the starting of the buzzer 306 and the alarm lamp 308 connected to one side of the PLC control board 302 control circuit board 304, so that the leakage condition is informed to a user, when the user overhauls, the push rods 2021 on the two sides are firstly turned over to be collinear with the movable rod 2023, then the two push rods 2021 are simultaneously pushed inwards, the movable rod 2023 drives the first clamping block 2024 to move inwards, the first spring 2025 contracts, the first clamping block 2024 is separated from being in contact with the connecting block 207 after pushing for a short distance, then the armrest 206 is lifted, so that the armrest 206 drives the protective shell 201 to turn over by taking the connecting block 207 as a central axis, after the protective shell 201 is turned over to a certain angle, the push rod 2021 and the protective shell 201 are released, the protective shell 201 is kept fixed by the damping feeling between the connecting block 207 and the inner wall of the connecting groove 208, the first clamping block 2024 is driven by the first spring 2025 to abut against one side of the connecting block 207, in the process of turning over the protective shell 201, the pressing block 307 is separated from the contact with the connecting switch 305, the circuit board 304 is in a closed state, the buzzer 306 and the alarm lamp 308 are turned off, then the two detection probes of the electric leakage detector 701 are sequentially connected with the electric appliance circuit, the specific position of electric leakage can be quickly detected, the electric leakage detector 701 and the circuit are arranged and returned after the maintenance is finished, then the protective shell 201 is covered to return the connecting block 207, the first clamping block 2024 is clamped with the connecting block 207 under the driving of the first spring 2025, the pressing block 307 abuts against the connecting switch 305, and the circuit board 304 is kept in an operating state, finally, the push rod 2021 is turned over into the storage tank 210.
The specific models and specifications of the leakage detecting chip 301, the PLC control board 302, the circuit board 304, and the leakage detector 701 are determined according to actual use conditions.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
