Da diferencia ya ya hingi explosivas, Ar adhieren varios requisitos únicos:
1. Categoría ntsa̲ explosiones, 'Mui, and Temperature Group: These are defined by national standards.
2. Types of Explosion-proof Protection:
There are five main types – Ininflamable, Aumento ar Ts'ut'ubi, Presión positiva, antichispas, and dust explosion-proof. They can also be a combination of these types or be of a composite or special kind.
3. Mfa̲ts'i bi eléctricas:
Classified into three categories – I, II, ne III. The purpose is to prevent electric shocks from accessible parts or conductors at different potentials, which might ignite explosivo Mezclas.
Ar klase I: Based on basic insulation, conductive parts that are normally non-live and accessible are connected to a protective earth conductor in the fixed wiring.
Ar klase II: Uses double or reinforced insulation as safety measures, without Ha̲i.
Ar klase III: Operates on a safe voltage not exceeding 50V and doesn’t produce higher voltages.
Ar klase 0: Relies solely on basic insulation for protection.
Most explosion-proof lighting fixtures fall under Type I, with a few being Type II or III, such as all-plastic explosion-proof lights or explosion-proof flashlights.
4. Ar 'ba̲ts'i jar carcasa:
Various protection methods for the enclosure are used to prevent the ingress of dust, solid objects, ne ar dehe, which could lead to sparking, short-circuiting, or compromising the electrical insulation. Characterized by “IP” followed by two digits, the first digit represents protection against contact, sólidos, or dust (nä'ä da ndezu̲ 0-6), ne ar mfe̲tsi kontra ar dehe (nä'ä da ndezu̲ 0-8). As sealed fixtures, explosion-proof lights have at least a level 4 dust protection.
5. Material of Mounting Surface:
Indoor explosion-proof lights might be mounted on ordinary combustible surfaces like wooden walls and ceilings. These surfaces must not exceed a safe Tsoxpa due to the light fixtures.
Based on whether they can be mounted directly on ordinary combustible materials, they are categorized into two types.
Summary – “How are explosion-proof lights different from regular lights?”: Regular lights are used in non-hazardous locations without inflamable gases wa ya polvo. Unlike explosion-proof lights, they lack explosion-proof grades and types. Regular lights mainly serve illumination purposes, while explosion-proof lights not only provide illumination but also offer explosion protection, ensuring the safety of personnel and preventing property damage.
