વિસ્ફોટ-પ્રૂફ ઇલેક્ટ્રિકલ ઇક્વિપમેન્ટ ઓપરેટિંગ પર્યાવરણ

GB3836.1—2010 મુજબ “વિસ્ફોટક વાતાવરણનો ભાગ 1: સાધનસામગ્રી સામાન્ય જરૂરિયાતો,” વિસ્ફોટ-પ્રૂફ વિદ્યુત ઉપકરણો વાતાવરણીય વાતાવરણમાં કામગીરી માટે રચાયેલ છે. લાક્ષણિક વાતાવરણીય પરિસ્થિતિઓમાં સમાવેશ થાય છે:

1. થી વાતાવરણીય દબાણ શ્રેણી 0.08 પ્રતિ 0.11 MPa;

2. એન ઓક્સિજન concentration of 21% (વોલ્યુમ દ્વારા) પ્રમાણભૂત હવામાં, with other inert gases like nitrogen constituting 79% (વોલ્યુમ દ્વારા);

3. An ambient તાપમાન between -20°C and 60°C.

The operational environment of electrical equipment is vital for its safety. દાખલા તરીકે, 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, ગંભીર કિસ્સાઓમાં, ખામી. Specifically for વિસ્ફોટ-પ્રૂફ ઇલેક્ટ્રિકલ સાધનો, exceeding the prescribed temperature range could compromise the explosion-proof integrity of certain types.

તદુપરાંત, the air’s oxygen content significantly affects the safety of explosion-proof electrical devices. Operating equipment intended for વિસ્ફોટક components in an “oxygen-rich” setting may pose risks. આવા વાતાવરણમાં, the altered દહન properties of flammable gases can challenge the normal function of equipment designed for standard conditions.
