Display and control equipment for man-machine interaction for switch apparatus

Abstract

Display and control equipment for man-machine interaction for a switch apparatus comprises an independent display and control module and an independent handheld module, wherein the display and controlmodule is connected with the switch apparatus for communication; the display and control module is connected with the handheld module in an assembled manner; the handheld module supplies power for the display and control module; or the display and control module is mounted in a cabinet door module, and the cabinet door module is connected with the display and control module and supplies power forthe display and control module; or the display and control module is fixedly connected with the handheld module and then is mounted in the cabinet door module, the cabinet door module is connected with the display and control module and supplies power for the display and control module, and the cabinet door module is connected with the handheld module and charges the handheld module; and the modular display and control equipment can be randomly switched over between the handheld module and the cabinet door mode, and the compatibility of the display and control equipment is improved.

Description

technical field [0001] The invention relates to the field of voltage electrical appliances, in particular to a display and control device for man-machine interaction of switching electrical appliances. Background technique [0002] In many industrial application environments, it is necessary to install a human machine interface (Human Machine Interface, HMI for short) for information and data exchange between users and industrial control equipment and systems. In low-voltage electrical products, to use human-machine interface equipment, it is necessary to provide products with communication functions. Control and Protective Switching Devices (CPS for short), as a control and protection component in a low-voltage electrical appliance, integrates the functions of circuit breaker, contactor, and thermal relay, and also has a communication function with a communication interface. [0003] In the existing technology, low-voltage electrical components such as CPS and motor protec...

AI Technical Summary

Problems solved by technology

[0003] In the existing technology, low-voltage electrical components such as CPS and motor protector can be equipped with communication HMI, which are usually called display and control unit, operation display and control module, operator communication unit, etc. The same display and control device can be used in a single way, portable and hand-held The use and installation of fixed cabinet doors cannot be balanced
