Problems solved by technology
The existing judgment method is blind and unpredictable. It can only analyze the possibility of condensation in the current temperature and humidity, and cannot predict the impact of the current control on the temperature and humidity adjustment equipment on the future. The conditions for the occurrence of condensation are very complicated. Blindly choosing to adjust temperature or humidity may have no effect or even be counterproductive, so temperature and humidity control needs to be predictable

Embodiment 1
[0029] A method for intelligently adjusting temperature and humidity of a switchgear, comprising the following steps:
[0030] Step 1: the number of training rounds is set; the last round flag is set to be 0; the number of training rounds is 10 in the present embodiment;
[0031] Step 2: Determine whether the last wheel flag is 1; if yes, go to step 3; otherwise, go to step 4;
[0032] Step 3: Set the accumulative value of temperature and humidity to 0;
[0033] Step 4: Initialize the virtual environment module of the simulated switchgear: the virtual environment module includes a value table, the row label of the value table is state, and the column label is operation; the operation includes the increase or decrease of temperature and humidity; the number of training times is set. In the embodiment, the training times is 20; such as state s 1 =(20,60) refers to temperature T=20℃, relative humidity RH=60%; operation such as temperature increase of 0.1℃; value of value table ...

The invention discloses an intelligent temperature and humidity adjustment method of a switchgear, which includes parameter setting, initialization of a virtual environment module of a simulated switchgear, state inspection, selection operation, evaluation of the possibility of condensation, and temperature and humidity control steps. The present invention establishes a virtual environment state for the temperature and humidity at each moment, simulates the increase and decrease of the actual temperature and humidity for evaluation, and can automatically give the most reasonable temperature and humidity control strategy after multiple trainings, and can adjust in time to reduce the condensation of the switch cabinet problems and improve the stability of power system operation.
Description
technical field [0001] The invention relates to a temperature and humidity adjustment method of a switch cabinet, in particular to an intelligent temperature and humidity adjustment method of a switch cabinet, belonging to the technical field of electrical equipment operation and maintenance. Background technique [0002] Switchgear is an important electrical equipment in the power system, and the corresponding complete sets of equipment have been widely used in substations. However, in recent years, explosion accidents in the switchgear have often occurred, which has brought major challenges to the stable operation of the power system. Work safety factor of personnel. However, due to the closed operation state of the switchgear and the air is not easy to circulate, high temperature and high humidity problems often occur, which is just easy to cause condensation. Condensation may cause short-term partial discharge, which in the long run will cause irreversible damage to the...
