Requirements For Monthly Average Environmental Parameters Of High Voltage Disconnect Switches

This indicator is typically used to describe the relative humidity of the installation or operating environment. For example, in the operating conditions of product High Voltage Disconnect Switch, the monthly average ambient humidity must not exceed 90%.

Excessive humidity can lead to a decrease in insulation performance, thereby affecting the reliability and safety of the switch. Maintaining the monthly average humidity below 90% helps maintain the long-term stable operation of the equipment.

This regulation also applies to requirements regarding environmental factors such as dust, pollution levels, corrosive gases, and chemical impurities. For example, in the environmental conditions of some power distribution equipment, in addition to humidity, there are also restrictions on pollution levels and chemical corrosion.
