The invention discloses a permanent magnet switch mobile power supply, and belongs to the technical field of electrical technology. The permanent magnet switch mobile power supply comprises a chargingcircuit, an isolation discharging circuit, a trigger circuit, an energy storage circuit, an external expansion interface circuit and two power supply circuits. One power supply circuit passes throughthe charging circuit and the energy storage circuit to be connected with the external expansion interface circuit, and the other power supply circuit passes through the trigger circuit, the isolationdischarge circuit and the energy storage circuit to be connected with the external expansion interface circuit. An electrolyte capacitor or a thin-film capacitor is arranged in the energy storage circuit, and a discharge interface is arranged outside the isolation discharge circuit, so that the discharge access of different inductive loads is provided. The power supply can be directly compatiblewith the discharge circuit of a circuit breaker driving power supply, the passive situation that the circuit breaker cannot be emergently processed when the circuit breaker power supply breaks down can be effectively avoided only through the interface butt joint, the accident losses are reduced, and the power supply can be widely applied to a permanent magnet type vacuum circuit breaker and is movable and portable and can be just externally connected with an alternating-current and direct-current power supply.
Description
technical field [0001] The invention belongs to the technical field of electrical technology, and in particular relates to a permanent magnet switch mobile power supply. Background technique [0002] In the prior art, when the driving power of the vacuum circuit breaker fails to operate or cannot be charged, the circuit breaker cannot operate in an emergency and needs to be powered off for maintenance, which will cause certain accident losses. Contents of the invention [0003] The invention provides a permanent magnet switch mobile power supply, which has the characteristics of emergency treatment of the passive situation of the circuit breaker and reduction of losses. [0004] In order to achieve the above object, the present invention provides the following technical solutions: a permanent magnet switch mobile power supply, including a charging circuit, an isolated discharge circuit, a trigger circuit, an energy storage circuit, an external expansion interface circuit a...
