The invention provides a multi-loop intelligent control circuit, a multi-loop intelligent control terminal, a power distribution cabinet and a multi-loop power distribution control method, the multi-loop intelligent control terminal comprises an upper shell and a lower shell, the upper shell and the lower shell are connected to form a cavity, and the multi-loop intelligent control terminal furthercomprises a voltage acquisition interface, a DC24V interface, a communication interface and a debugging interface; wherein the upper shell is arranged above the lower shell, the lower shell is detachably connected with the upper shell, and the upper shell is provided with a switch butt joint socket, a switch mounting port, a voltage acquisition interface, a DC24V interface, a communication interface and a debugging interface. The invention has the beneficial effects that the structure is simple, the design is reasonable, the switch butt joint socket and the switch mounting port are arranged,the switch can be conveniently installed, a loop detection function is achieved through the arrangement of the voltage collection interface, the requirements of flexible and changeable on-site use environments can be met, loops can be randomly selected for combined detection, maintenance and transformation are convenient when a load or a use requirement changes, and the terminal is suitable for adistribution box or a distribution cabinet with more loops.

Description

technical field [0001] The invention belongs to the technical field of distribution boxes, and in particular relates to a multi-loop intelligent control circuit, a multi-loop intelligent control terminal, a power distribution cabinet and a multi-loop power distribution control method. Background technique [0002] The traditional distribution box has no detection function, or only has the detection function of a specific circuit, which cannot meet the flexible and changeable use environment on site, cannot randomly select circuits for combined detection, and is not maintainable and retrofittable when the load or usage requirements change. Especially for distribution boxes with many circuits, it is difficult to upgrade and modify, and the upgrade and maintenance costs are high. [0003] In the face of complex and diverse power distribution parameter sampling requirements, the original simple power distribution parameter monitoring and control system that operates independentl...
