Power supply and CPS measurement and control device

Abstract

The invention discloses a power supply and CPS measurement and control device, which comprises a shell, wherein the shell is provided with a control module, a display module and control keys, is provided with a power supply electric power parameter acquisition input interface and a CPS state parameter acquisition input interface, and is further provided with a CPS control signal output interface,the fixed connection end of the CPS control signal output interface is electrically connected with a corresponding output pin on the control module, the shell is provided with a control display surface, the display surface of the display module is exposed out of the control display surface, the input end of the display module is electrically connected with a corresponding output pin on the controlmodule, the display module is used for displaying the power parameters and CPS state parameters of a dual power supply, and each control key is used for controlling the start and / or stop of one corresponding CPS. The power supply and CPS measurement and control device has the advantages that wiring is easy, a cabinet surface is simple, visual and easy to operate, the manufacturing cost of a motorcontrol cabinet is reduced, and the device has an event recording function and facilitates troubleshooting.

Description

technical field [0001] The invention belongs to the field of motor control devices and instruments, in particular to a power supply and CPS measurement and control device. Background technique [0002] CPS is the abbreviation of "Control and Protective Switching Device" in English, and "Control and Protective Switching Device" in Chinese. CPS is a new type of low-voltage electrical appliances that have appeared in recent years. [0003] CPS adopts a modular single product structure type, integrating the main functions of traditional circuit breakers (fuse), contactors, overload (or overcurrent, phase failure) protection relays, starters, isolators, etc. CPS overcomes the many shortcomings of electrical products (discrete components) with different assessment standards when they are combined together by using different assessment standards (such as circuit breakers, protective relays and contactors). The uncoordinated phenomenon between characteristics and control characteri...

AI Technical Summary

Problems solved by technology

[0005] At present, motor control cabinets using CPS are widely used in the fields of water pumps, fans and fire protection. figure 1 As shown), the quantity is more than 10, multiple instruments and control switches need to be installed on the cabinet door one by one, and each instrument or control button needs to be routed and wired, which will lead to cumbersome and complicated installation procedures and low installation efficiency. It is difficult to lift, which affects the processing and production efficiency of the motor control cabinet

In addition, there are more than 10 instruments and control switches on the cabinet door, which also makes the instructions on the cabinet surface messy and difficult to distinguish, which increases the difficulty of use for users
