Switchgear Room Temperature
As an illustration the diagram below shows simple room layout consisting of a 22 kv switchboard some dc and scada panels click for a larger image.
Switchgear room temperature. Design criteria for room ventilation. The high humidity level in a switchgear room causes several damaging effects. Switchgear heat emissions and temperature rise is something of a snake and mongoose affair between switchgear manufacturers and designers clients a small dx split aircon unit often serves to eliminate any unseemly arguments after the fact regards oms let the wind blow you across a big floor. Each switchroom is unique and needs to be considered in relation to the specific equipment which will be installed.
What affects the operating temperature within lv switchgear photo credit. Dust content may also be set. As a general guidance rule the temperature within the low voltage switchgear should not exceed 50 55ºc. It results in condensation of moisture on the switchgear surfaces when there is a sudden change in temperature because of outside weather or inside air conditioning factors.
If switchroom or plant room ambients are typically considered to be up to 25 c this relates to a 25 30k rise above ambient. In order to design a good ventilation of switchgear and transformer rooms the air in the room must meet various requirements. The condensed moisture on the switchgear surface is detrimental to switchgear.
