摘要： This application provides a power supply end, a wireless power supply system, a power supply method, and a computer storage medium, to improve wireless power supply efficiency. The power supply end includes a transceiver and a plurality of radiation circuits. The transceiver is configured to: generate a charging signal including an electromagnetic wave of at least one frequency band, and separately provide the charging signal for the plurality of radiation circuits. Each of the plurality of radiation circuits can transmit an electromagnetic wave of one or more target frequency bands. The plurality of radiation circuits include a first radiation circuit and a second radiation circuit. One or more target frequency bands included in an electromagnetic wave transmitted by the first radiation circuit are different from one or more target frequency bands included in an electromagnetic wave transmitted by the second radiation circuit. Each of the plurality of radiation circuits is configured to: filter the charging signal, and if a target electromagnetic wave is filtered out, transmit the target electromagnetic wave, where a frequency band corresponding to the target electromagnetic wave is included in one or more target frequency bands corresponding to an electromagnetic wave that can be transmitted by a corresponding radiation circuit.

摘要： This application discloses a current detection apparatus, an electric energy detection apparatus, and a method for controlling a current detection apparatus. The current detection apparatus includes a first transformation unit, a power supply unit, a current detection unit, and a processing unit. The first transformation unit includes a hollow part, a detected cable passes through the hollow part, and the first transformation unit is configured to generate a first induction electrical parameter and a second induction electrical parameter based on an actual current on the detected cable. The power supply unit is connected to the first transformation unit. The current detection unit is connected to the first transformation unit, and converts a current in the second induction electrical parameter into a first current. The processing unit is connected to the power supply unit and the current detection unit, and calculates a current value on the detected cable. Based on the apparatus provided in this application, an installation location of the detection apparatus can be prevented from being limited by an electrical connection point. When the current on the detected cable is detected in real time, a production compliance level of the detection apparatus can be increased, and costs can be reduced. In addition, no additional power supply needs to be configured for the detection apparatus, thereby eliminating a limitation of the power supply on installation of the detection apparatus.

摘要： This application provides a control circuit used for a circuit breaker, and an electronic device. The control circuit includes a first coil, a second coil, a switch module, and an adjustable current supply module. A first end of the switch module is coupled to one end of the first coil, the other end of the first coil is coupled to one end of the adjustable current supply module, the other end of the adjustable current supply module is coupled to a second end of the switch module, a third end of the switch module is coupled to one end of the second coil, and the other end of the second coil is coupled to a fourth end of the switch module. The switch module can control a direction of a first current. The adjustable current supply module can change a magnitude of the first current. The first current is used to excite the first coil to generate a first magnetic field and excite the second coil to generate a second magnetic field, and the first magnetic field interacts with the second magnetic field, to control closing or opening of the circuit breaker. According to this application, the circuit breaker can be controlled to be quickly open, and a service life of the circuit breaker can be further improved.

摘要： This application provides a box and an electronic device. The box includes a box body, a cover, and a plurality of explosion venting assemblies The box body has an opening. The cover seals the opening of the box body, so that enclosed space is formed inside the box body. The plurality of explosion venting assemblies are disposed at spacings in a circumferential direction along an edge of the opening of the box body. Each explosion venting assembly includes a fastener and a sleeve covering the fastener. The fastener is configured to fasten the cover and the box body, and fit with the box body and the cover to press against the sleeve. The sleeve has critical buckling load. The explosion venting assemblies of the box utilize a linear buckling property of the sleeves. When the box experiences an explosion, after the cover is separated from the box body for explosion venting, the opening of the box body can be re-sealed, so that there is no opening or only a quite small opening between the cover and the box body. This improves explosion-proof performance of the box, reduces a probability of personal injury when the box experiences an explosion, and improves safety of using the box.
