A circuit breaker electronic controller and its power supply method

Abstract

The invention discloses an electronic controller of a circuit breaker and a power supply method of the electronic controller. The electronic controller comprises a control unit, and a display unit and an input unit, which are respectively coupled with the control unit, wherein the electronic controller of circuit breaker further comprises a battery unit used for supplying power to the control unit and the display unit. The battery unit is integrated in the electronic controller of circuit breaker disclosed by the invention to directly supply power to the controller, parameters can be set at the non-working state of the circuit breaker, and no auxiliary power supply is necessarily carried, so that the application is more convenient.

Description

technical field [0001] The invention relates to the field of power distribution control of low-voltage electrical appliances, and more specifically relates to an electronic controller of a circuit breaker and a power supply method thereof. Background technique [0002] Existing electronic low-voltage circuit breakers generally use dial switches, rotary coding switches, etc. to set parameters for the electronic circuit breakers. This setting method is simple and can be set without the electronic circuit breaker being in working condition. But this setting method is not intuitive enough, and can only be counted according to the position of the file, and the resolution of the number setting is poor. At present, there is also an electronic circuit breaker parameter setting method with a liquid crystal display and a keyboard. This setting method is friendly and intuitive, and parameters can also be set arbitrarily according to needs, but the electronic circuit breaker needs an e...

But this setting method is not intuitive enough, and it can only be counted according to the gear position, and the resolution of the counting is poor

At present, there is also an electronic circuit breaker parameter setting method with a liquid crystal display and a keyboard. This setting method is friendly and intuitive, and parameters can also be set arbitrarily according to needs, but the electronic circuit breaker needs an external auxiliary power supply in the non-working state. It is extremely inconvenient for users to set up, and the auxiliary power supply is used as an accessory. In some circulation links, it cannot be delivered to end users, which makes this kind of application less common.
