Ni ibamu si GB3836.1-2010 “Awọn ibẹjadi Atmospheres Apá 1: Equipment General awọn ibeere,” Awọn ohun elo itanna-ẹri bugbamu jẹ apẹrẹ fun iṣẹ ni awọn agbegbe ayika. Awọn ipo oju aye aṣoju pẹlu:
1. Iwọn titẹ oju aye lati 0.08 si 0.11 MPa;
2. An atẹgun concentration of 21% (nipa iwọn didun) ni boṣewa air, with other inert gases like nitrogen constituting 79% (nipa iwọn didun);
3. An ambient otutu between -20°C and 60°C.
The operational environment of electrical equipment is vital for its safety. Fun apẹẹrẹ, explosion-proof electrical devices are often specified to operate in temperatures between -20°C to 40°C. Lower atmospheric pressure, which implies thinner air, can adversely affect the cooling efficiency of electrical devices. Likewise, fluctuations in atmospheric temperature influence cooling performance, directly affecting the device’s operational efficiency.
When electrical equipment’s designed environment diverges from the actual atmospheric conditions, it’s crucial to adjust the parameters, particularly for high-power devices, to maintain safety standards.
The designated operational environment temperature, set during the design phase, outlines the permissible temperature range for the equipment’s operation. This environment temperature forms the foundation for all the equipment’s performance indicators. Discrepancies between the actual and designed environments can lead to underperformance or, ni awọn iṣẹlẹ ti o lewu, aiṣedeede. Specifically for bugbamu-ẹri ẹrọ itanna, exceeding the prescribed temperature range could compromise the explosion-proof integrity of certain types.
Jubẹlọ, the air’s oxygen content significantly affects the safety of explosion-proof electrical devices. Operating equipment intended for bugbamu components in an “oxygen-rich” setting may pose risks.
