Therefore, in order to reduce the interference of dust to the low-voltage power distribution cabinet, an intelligent low-voltage power distribution cabinet power distribution control system is selected for use so as to reduce dust accumulation in the low-voltage power distribution cabinet.

In the above steps, the intelligent low-voltage power distribution cabinet power distribution control system provided by the embodiment integrates the high-precision sensor, and can continuously and real-timely monitor the dust accumulation degree inside the low-voltage power distribution cabinet. Once the dust accumulation reaches the preset critical value, the system can automatically trigger a cleaning program, and the advanced dust collection or blowing technology is utilized to efficiently and thoroughly remove dust accumulation in the cabinet, so that the dust is prevented from corroding precise electronic elements and electrical connection points in the power distribution cabinet, the service life of equipment is obviously prolonged, the failure rate caused by the dust is reduced, the intelligent control on the low-voltage power distribution cabinet is realized, and the overall operation efficiency and stability are improved. Meanwhile, an advanced algorithm is adopted by a built-in judging module of the system, so that the current dust accumulation degree can be accurately compared with a preset standard accumulation degree threshold value. And conversely, if the dust amount is below the safety level, cleaning is not performed, so that excessive or unnecessary cleaning operation is avoided, precious energy resources are saved, manual intervention in the maintenance process is reduced, and the operation and maintenance efficiency is greatly improved.

In one embodiment, the detection area is set at key parts such as bus lap joint terminal, connector, dense wire arrangement position, etc. according to GB/50303-2015.
Specifically, when the light wave emitted by the light source emitter encounters dust particles on the surface of the internal bus bar, interaction can occur, so that the light wave deviates from the original propagation direction, light with the same frequency as the incident light is emitted in all directions, but the intensity is weakened compared with the emitted light, so that light scattering is generated, and when the reflected light receiver receives the light scattered by the dust on the surface of the internal bus bar, the dust thickness can be reversely calculated, so that the accurate acquisition of the dust accumulation degree on the surface of the internal bus bar of the low-voltage power distribution cabinet is realized.
In practice, the light source emitter may be implemented by a laser emitter in the prior art, and the reflected light receiver may be implemented by a photoelectric sensor in the prior art, which is not described herein.
In detail, the dust accumulation degree can be obtained through analysis by the light-emitting scattering method, and can also be obtained from a filter membrane sampling method or a clustering analysis algorithm and an analytic hierarchy method in the prior known technology, and it is noted that the dust layer with the thickness exceeding 50mm can affect the normal operation of the power distribution cabinet according to the standard of GB/12476.1-2013, so that when the dust accumulation degree is obtained, the obtaining precision is adjusted to be 1mm so as to ensure that the accurate value of the dust accumulation thickness can be accurately captured.

As the preferable technical scheme of the power distribution control system of the intelligent low-voltage power distribution cabinet, the judging module compares the dust accumulation degree and the standard accumulation degree which are obtained by the detecting module;
If the dust accumulation degree is greater than the standard accumulation degree, the judging module sends a cleaning instruction to the cleaning module;
If the dust accumulation degree is less than the standard accumulation degree, the judging module keeps silent;
the standard accumulation degree is related to the output voltage of the low-voltage power distribution cabinet.
In detail, the output voltage of the low-voltage power distribution cabinet used in daily work is 220V-660V, dust is accumulated on the surface of a device in the low-voltage power distribution cabinet, insulation strength is easily reduced, discharge is caused, particularly, a circuit board is easily damaged under the condition that moisture or micro-condensation exists at the same time, and a control system is easily damaged or malfunctioned, wherein the dust can corrode a printed wire in the circuit board, metal pins of electronic components and the like, even mold break, and control is invalid or does not work. The larger the output voltage of the low-voltage power distribution cabinet is, the larger the influence of dust on equipment is caused, so that the standard accumulation degree is 40 mm-50 mm according to the output voltage of the low-voltage power distribution cabinet. For example, the output voltage of the low-voltage power distribution cabinet is 480V, and the standard accumulation degree is 45mm.
