For example, the power distribution cabinet 100 may be affected by the ambient temperature inside the power distribution cabinet 100. Therefore, for different external temperatures, different temperature intervals are set, so that the solution efficiency of the power distribution cabinet 100 is improved.
Further, the power distribution cabinet 100 periodically acquires the external environment temperature.

For example, when Tout is 10 ℃, K is 0.7, and Td is-5 ℃, then T1 is 5.5 ℃; t2 ═ 12.5 ℃; t3 ═ 19.5 ℃; t4 ═ 26.5 ℃; t5 ═ 33.5 ℃, the first temperature interval is (∞, 5.5), the second temperature interval is (5.5, 12.5), the third temperature interval is (12.5, 19.5), the fourth temperature interval is (19.5, 26.5), and the fourth temperature interval is (33.5, + ∞).
Preferably, a first temperature range, a second temperature range, a third temperature range, a fourth temperature range, and a fifth temperature range are set according to a temperature look-up table by the external environment temperature detection data.
For example, by presetting a temperature comparison table in the power distribution cabinet, the temperature comparison table can be inquired, and the corresponding first temperature interval, the second temperature interval, the third temperature interval, the fourth temperature interval and the fifth temperature interval can be directly obtained according to the external environment temperature detection data, so that the speed of replacing the temperature intervals is increased, and the response can be conveniently made at the first time.
Specifically, referring to fig. 4, each temperature lookup table includes a plurality of different first temperature data, and a plurality of first temperature interval data, second temperature interval data, third temperature interval data, fourth temperature interval data, and fifth temperature interval data corresponding to the plurality of different first temperature data. For example, when the external environment temperature is-20 ℃, a first temperature interval 1, a second temperature interval 1, a third temperature interval 1, a fourth temperature interval 1 and a fifth temperature interval 1 are corresponded; when the external environment temperature is-19 ℃, a first temperature interval 2, a second temperature interval 2, a third temperature interval 2, a fourth temperature interval 2 and a fifth temperature interval 2 are correspondingly arranged; until the external environment temperature is 50 ℃, a corresponding first temperature interval 71, a second temperature interval 71, a third temperature interval 71, a fourth temperature interval 71 and a fifth temperature interval 71.
Preferably, the external environment temperature and the power distribution cabinet environment temperature are uploaded to the management platform in real time through the intelligent gateway 130. The management platform can detect the information of the power distribution cabinet in real time, and if the power distribution cabinet is abnormal, the power distribution cabinet can also make a first-time reaction.
Further, the intelligent low-voltage power distribution cabinet management method further includes, for example:
step S110, setting a first humidity interval, a second humidity interval and a third humidity interval;
