AI Technical Summary

Problems solved by technology

[0003] With the development of science and technology, the unattended substation has become the development trend of the future management system; switch cabinets with different voltage levels are installed in the switch room of the substation. The indoor is sealed. When the indoor ambient temperature is too high, the axial flow fan in the switch room cannot work automatically and cannot dissipate heat to the outside. If the fan is switched to manual operation, the cooling fan cannot stop automatically. The long-term operation of the fan may cause damage to the power supply. Waste may also cause the fan to burn out. When the environment is too humid, the above problems also exist in controlling and reducing the humidity in the switch room; as we all know, temperature and humidity have a great impact on the safe operation of primary and secondary equipment. Running in a high temperature and high humidity environment will not only accelerate the corrosion and insulation aging of the primary electrical equipment, but the secondary equipment will be grounded, the terminal row will be corroded, and poor contact will cause malfunction or refusal to operate, and even cause insulation breakdown or fire accidents

[0004] At present, the substation does not have a system for automatic monitoring of the indoor environment, and can only rely on manual start and stop of the fan. During the entire process of being on duty in the substation, the personnel on duty must have a high sense of responsibility and monitor and understand the switch of the substation at any time. Indoor temperature and humidity values, the fan can be switched on and off at any time according to the temperature change, and the dehumidifier can be switched on and off at any time according to the humidity change, so as to control the temperature and humidity in the switch room of the substation within the specified range, which increases the difficulty of substation maintenance; Improvement of temperature and humidity monitoring system in substation
