Embodiment Construction
[0021] The above and other technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.
[0022] refer to figure 1 , the present invention provides a plug-and-play detection method for an intelligent control cabinet, including step S100, step S200, step S300, and step S400.
[0023] In step S100, the power supply state of the power supply of the intelligent control cabinet is obtained, and a corresponding power supply state detection signal is generated, wherein, when the power supply state detection signal is at a low level, it means that the power supply state is abnormal, and when the power supply state detection signal is at a high level, it represents The power supply state is normal; the power state between the aviation plug and the cable distribution frame is also obt...

The invention discloses a detection method for plug and play of an intelligent control cabinet. The method comprises the following steps: 1, the power supply state of a power supply of the intelligent control cabinet is acquired, corresponding power supply state detection signals are generated, the energized state between an aerial plug and a cable distribution frame is also acquired, and corresponding energized state detection signals are generated; 2, according to the power supply state detection signals and the energized state detection signals, the connection state between the aerial plug and the cable distribution frame is detected; 3, one of the aerial plug and the cable distribution frame is loaded with charged particles, and the rest receives the charged particles, and a lightly-abnormal connection state or a heavily-abnormal connection state between the aerial plug and the cable distribution frame is determined; and 4, when the connection state between the aerial plug and the cable distribution frame is determined to be lightly abnormal or heavily abnormal, corresponding prompting is carried out.
Description
technical field [0001] The invention relates to an electric power system, and more specifically relates to a plug-and-play detection method for an intelligent control cabinet. Background technique [0002] Power system status information plays an important role in the operation and analysis of power systems. In fact, state information can be used for many purposes, including system safety and accident analysis, system optimization, and even the creation and operation of electric energy markets. [0003] According to the disadvantages of the wiring method of "control cable + terminal block" for secondary wiring in the existing substation, it can be considered to replace the original control cable with aviation plugs to realize "plug and play" of secondary equipment. The original secondary equipment backplane plug-ins correspond to independent aviation plugs, and each plug-in hole that needs to lead out cables corresponds to a ferrule in an aviation plug. When the secondary e...
