Control method for intelligent load controller for power distribution branches

Abstract

The invention discloses an intelligent load controller for power distribution branches and a control method for the controller and relates to an electronic technology controller and the controlling method for the controller. The controller comprises a control center, a power supply unit, a drive unit, an execution unit, a data input controller and an alarming and display unit. Output ends of the power supply unit and the data input controller are connected with an input end of a programmable logic controller (PLC) control center. Input ends of the drive unit and the alarming and display unit are connected with an output end of the control center. An input end of the execution unit is connected with an output end of the drive unit. The control method comprises that a control center determines whether loads are matched with currents according to input electrical load poser and currents and decides whether to connect the power distribution branches to achieve selection training on wires and switch equipment of a power supply and distribution system. The intelligent load controller can be used as a support device for 'an intelligent low-voltage power supply and distribution training system' and an upgrading and updating product for an intelligent examination answering apparatus of a machine tool circuit, and a physical platform is provided for professional skill training of various vocational schools.

Description

technical field [0001] The invention relates to an electronic technology controller and a control method thereof, in particular to an intelligent load controller of a distribution branch circuit and a control method thereof. Background technique [0002] In the existing distribution operation training of power supply and distribution system, it is generally only required to complete the wiring work according to the design plan of the system, that is, to connect the wires, and there is no need to consider the power of the load, wires and switch specifications. This just ignores the basic theoretical issues in the course of "Power Supply and Distribution Technology", that is, to reasonably select the specifications of wires and switchgear according to the size of the load. In actual production and life, there are many design and installation problems in low-voltage power supply and distribution. Non-standard problems, on the one hand, tripping and blown fuses often occur due t...

Problems solved by technology

The controller has the following disadvantages: it can only control the on-off of the circuit according to the fault number. In actual operation, as long as the on-off of each branch is measured, the fault number is determined according to the fault table, and then the corresponding fault number is input. The circuit can be connected, and the controller obviously cannot complete the matching judgment function of load and current.

[0004] Similarly, in the training assessment of machine tool circuit on-off control, the machine tool circuit intelligent assessment clicker also has a fatal flaw, that is, once the fault number is leaked, even if the operator does not understand the circuit principle at all, he only needs to key in the corresponding key in the input device. fault number, the fault will be easily resolved, and the real evaluation of the power distribution control technology mastered by students cannot be realized
