دھماکہ پروف برقی آلات آپریٹنگ ماحول

GB3836.1—2010 کے مطابق “دھماکہ خیز ماحول کا حصہ 1: سامان کی عمومی ضروریات,” دھماکہ پروف برقی آلات کو ماحول کے ماحول میں کام کرنے کے لیے ڈیزائن کیا گیا ہے۔. عام ماحولیاتی حالات میں شامل ہیں۔:

1. سے ایک وایمنڈلیی دباؤ کی حد 0.08 کو 0.11 ایم پی اے;

2. ایک آکسیجن concentration of 21% (حجم کے لحاظ سے) معیاری ہوا میں, with other inert gases like nitrogen constituting 79% (حجم کے لحاظ سے);

3. An ambient درجہ حرارت between -20°C and 60°C.

The operational environment of electrical equipment is vital for its safety. مثال کے طور پر, 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, شدید صورتوں میں, خرابیاں. Specifically for دھماکہ پروف برقی آلات, exceeding the prescribed temperature range could compromise the explosion-proof integrity of certain types.

مزید, the air’s oxygen content significantly affects the safety of explosion-proof electrical devices. Operating equipment intended for دھماکہ خیز components in an “oxygen-rich” setting may pose risks. ایسے ماحول میں, the altered دہن properties of flammable gases can challenge the normal function of equipment designed for standard conditions.
