specific Embodiment 1

[0023] Specific embodiment 1: As shown in Figures 1 and 2, the low-voltage power distribution cabinet with a display control panel still has the same rectangular housing 1 as the traditional low-voltage power distribution cabinet, and an air switch 6, a current transformer 2, and an air switch 6 are installed inside. The lightning circuit breaker 4, the three-wire power switch 3 and the fuse 7 are also equipped with a graphic display system, which includes a graphic display device and a central processing unit. The central processing unit takes the microprocessor with the control program as the core, reads the data of the instruction input unit and the data acquisition unit under the control of the internal control program, and outputs the corresponding display data to the graphic display device after processing for graphic display device display; such as image 3 As shown, the central processing unit includes: an instruction input unit for inputting instruction information and...

specific Embodiment 2

[0024] Specific embodiment 2: Certainly, in order to improve processing speed, simplify circuit, central processing unit also is provided with two microprocessors respectively as real-time data acquisition processing unit and display and communication processing unit core, as Figure 4 As shown, the display and communication processing unit includes: an instruction input unit for inputting instruction information and an input memory for storing information input through the instruction input unit; The graphic storage of the symbolic image and the text library of the text; the display buffer memory for storing the real-time display content; A comparator for comparing the contents of the input memory and a comparison memory for storing the output result of the comparator; and a selector controlled by the output signal of the comparator, which selector is based on the content of the comparison memory Make the following choices: keep the content of the display buffer memory unchan...

Abstract

The power distributing cabinet in low voltage includes cabinet, air switch in cabinet, current transformer, and breaker etc. Characters are that the power distributing cabinet also contains graphics and text display device including data acquisition unit for collecting real time state information of distribution system, and CPU. Under control of CPU, data acquisition unit obtains real time state information of distribution system, and the text display device displays each switching value in the power distributing cabinet as well as state information and data value. Convenience is supplied by the invention for monitoring maintenance.

Description

technical field [0001] The invention relates to a low-voltage power distribution cabinet, in particular to a low-voltage power distribution cabinet capable of displaying internal power distribution structures and working states in the form of graphics, text and animation. Background technique [0002] The development of modern industrial technology has put forward higher requirements for the reliability of low-voltage power distribution system operation and its intelligent management, and the wide application of microprocessor technology and the substantial improvement in the reliability of computer systems have made intelligent low-voltage electrical components With the rapid development, the intelligent low-voltage electrical management system came into being. Compared with the development of comprehensive protection and system monitoring (SCADA system) of 6kV and above medium and high voltage systems and its application in power systems, as a low-voltage switchgear direct...
