    摘要: A circuit breaker and a power distribution system are provided. The circuit breaker includes a housing and an internal element disposed inside the housing. The housing includes a front panel and a rear panel that are disposed opposite to each other, the front panel is disposed with a button, a status display unit, and a power wiring port, and the rear panel is disposed with a power interface and a signal interface. The power wiring port and the power interface are connected to a circuit of a power distribution system. The signal interface is internally and electrically connected to the button, the status display unit, and the internal element, and the signal interface is externally configured to be electrically connected to a control unit disposed outside the housing. A control signal of the control unit implements working of the button, the status display unit, and the internal element.

    摘要: A magnetic sensor includes a printed circuit board and a tunnel magneto-resistance element. The printed circuit board includes a target trace. When the tunnel magneto-resistance element is installed, the tunnel magneto-resistance element is installed right above or right below the target trace, and a ratio of a distance D between a detection unit in the tunnel magneto-resistance element and an edge on a side of the target trace closest to the tunnel magneto-resistance element to a width W of the target trace is between 3.0% and 20.0%.

    摘要: A reverse power connection preventing circuit includes a diode and an actuation unit that are connected in series between a positive input terminal and a negative input terminal of a circuit breaker. A positive electrode of the diode points to the negative input terminal of the circuit breaker, and a negative electrode of the diode points to the positive input terminal of the circuit breaker. When a power supply is forward connected to the circuit breaker, the diode is cut off, there is no current on the actuation unit, and the reverse power connection preventing circuit is in a power-off state. When the power supply is reversely connected to the circuit breaker, the diode conducts, and the actuation unit is configured to prevent closing of the circuit breaker, and/or the actuation unit is configured to perform an alarm prompt, to perform an early warning.

    摘要: A power distribution system includes a backplane communication busbar and a circuit breaker. The backplane communication busbar includes at least one slot, and a first interface is configured in each slot. Each first interface is connected to a first resistor R1 having a different resistance value. A second interface of each circuit breaker is connected to a second resistor R2, and when the second interface of the circuit breaker is plugged in any first interface, a preset voltage interval corresponding to a resistance value of the first resistor R1 is uniquely determined by using a series circuit including the first resistor R1 and the second resistor R2.
