Aiming at the defect of the design of the original motor control cabinet in the background technology, the utility model leads to the failure detection efficiency and the risk of erroneous judgment when the motor fails. In this way, the outsourcing touch screen is adopted to carry out communication connection with the PLC controller, and the program of the PLC in the original device is redesigned through the edit configuration of the touch screen, so that once the motor fails to start, the touch screen can display and alarm, and the reason of the failure to start and the follow-up conditions can be clearly recorded, thereby greatly facilitating the judgment and processing of operation and maintenance personnel after the failure to start the motor. Based on the design principle, a control system for perfecting the starting of a high-voltage motor is provided.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a perfect control system that high-voltage motor starts, includes the motor control cabinet of installing at the scene, installs the PLC controller in it for control the start-stop of each motor, still including outsourcing touch-sensitive screen, the communication port of touch-sensitive screen pass through the data line with the communication interface of PLC controller is connected to realize the exchange of data, the touch-sensitive screen is used for the order and the time that take place for each motor interlocking condition of record and demonstration, the outer power supply line of drawing on the motor control cabinet binding post is connected with air circuit breaker's input, air circuit breaker's output is connected with DC power supply's input through the electric wire, DC power supply's output passes through the electric wire connection the touch-sensitive screen is supplied power.
As a further supplementary explanation of the above technical scheme, a fixed plate is installed in the motor control cabinet, the touch screen is embedded on the fixed plate, and the air circuit breaker and the direct current power supply are respectively installed on the fixed plate.
As a further explanation and limitation of the above technical solution, the type of the touch screen is MT6103iP.
Compared with a control system of a high-voltage motor which is not good, the utility model has the following advantages:
1. the utility model is connected with the original built-in PLC controller through the touch screen, can completely and clearly record the conditions of the interlocking condition of the high-voltage motor control system during starting and the fault reasons of the high-voltage motor during starting failure, can visually display and accurately find the fault reasons, saves time, and is greatly convenient for operation and maintenance personnel to comprehensively know each condition during starting and stopping of the high-voltage motor. 2. The touch screen with the core component is mature in technology and can be well adapted to the PLC with the core component of the high-voltage motor control system. 3. The power supply required by the touch screen is low in requirement, the power consumption is low, and the common commercial power can meet the requirement under the condition of ensuring the power supply reliability.
