Various explosion-proof electrical appliances and lamps have designated light sources, which are not allowed to be changed at will. Users should correctly select the light source according to the nameplate and operating instructions of the explosion-proof electrical lamps and lanterns. The design and selection of light sources for explosion-proof electrical appliances and lamps should be based on the principles of safety, efficiency and economy.
Safety
Electric light source is the most important heating element in explosion-proof electrical lamps and lanterns. Explosion-proof electrical lamps and lanterns should select the light source and design the explosion-proof type based on the heating condition and working principle of the light source.
The discharge elements inside the gas discharge lamp must be analyzed to see if they contain active and unstable chemical elements, their quantity and their properties in the cold state. For example, there are a sufficient number of unstable chemical elements in the cold state of the light source. , once the light source is broken, the active chemical elements in the lamp will react chemically with the moisture in the environment to generate heat, which may ignite explosive mixtures in the environment. This type of light source is strictly prohibited from use in explosion-proof electrical lighting fixtures.
Under abnormal conditions in which high-pressure lamps, high-pressure sodium lamps, metal halide lamps and ordinary fluorescent lamps are broken and damaged, the discharge tube or filament can still form an electrical circuit, causing the explosive gas and the hot discharge tube or filament to contact the machine. Larger, therefore, increased safety explosion-proof electrical lamps cannot use these light sources.
3. The light sources allowed for the increased safety explosion-proof lamps are: fluorescent lamps with a single plug without a starter, ordinary incandescent lamps and self-ballasted fluorescent high-pressure lamps. These light sources will be damaged even if the bulb is broken. Can break the circuit instantaneously. Among the above three types of light sources, the fluorescent light source without starter with a single plug has low surface temperature, high light efficiency, and good applicability in explosive and hazardous environments.
The same light source used in different explosion-proof lamps will have different temperature groups. For example, for incandescent lamps, when used in increased safety explosion-proof electrical lamps, the temperature group of the lamp is determined by the high temperature of the light source surface. Generally, it can only be set as , while when used in explosion-proof explosion-proof electrical lamps, the lamp shell is used It is possible to achieve 3 high surface temperatures in a fixed temperature group.
Efficiency
Efficiency mainly refers to high luminous efficiency. Choosing a light source with high luminous efficiency can reduce the number of lamps used and reduce energy consumption.
3. Reduce the temperature group of welding-proof lamps
On the premise of ensuring safety, reduce the temperature group of explosion-proof electrical lamps as much as possible to improve the applicability of explosion-proof electrical lamps. Giving full play to the performance of explosion-proof electrical appliances and lamps is a more practical issue in the design of explosion-proof electrical lamps and lanterns.
