[0003] However, if the current that the cable can withstand is less than the rated current of the circuit breaker, then when the current on the circuit breaker is slightly lower than the rated current, the circuit breaker will not be disconnected and the cable will heat up sharply, causing the outer insulation layer of the cable to accelerate. Aging, or even melting of the insulation layer, causing a short circuit and causing a fire

The application discloses a circuit breaker, a current matching method, an electronic device, and a computer-readable storage medium. The circuit breaker includes: a circuit breaker assembly, a detection assembly, and a control assembly, wherein the circuit breaker assembly includes a terminal, and the terminal is used to connect with a cable The detection component is connected to the terminal to generate an electrical signal related to the wire diameter of the cable; the control component is electrically connected to the detection component to receive the material of the cable connected to the terminal and the electrical signal fed back by the detection component, And determine the wire diameter of the cable according to the electrical signal, and determine the first safe current corresponding to the cable based on the material and wire diameter of the cable; wherein, the control component is also used to obtain the rated current corresponding to the circuit breaker, based on the first safe current and The rated current determines the second safe current corresponding to the circuit breaker. The above solution can reduce the probability of overloading of the circuit breaker and the cables connected to the circuit breaker, and improve the safety of the circuit breaker.
Description
technical field [0001] The present application relates to the technical field of electrical equipment, in particular to a circuit breaker, a current matching method, electronic equipment and a computer-readable storage medium. Background technique [0002] Today's society is inseparable from terminal power distribution and power consumption, and circuit breakers play a vital role in power safety. Existing circuit breakers usually automatically disconnect when the current is too large to protect the safety of the circuit. There are also some intelligent circuit breakers that can collect current, voltage, leakage, temperature and other data in real time and report them to the platform, so that the platform can remotely control the disconnection of the circuit breaker. Realize overload protection. [0003] However, if the current that the cable can withstand is less than the rated current of the circuit breaker, then when the current on the circuit breaker is slightly lower th...
