Class II explosion proof lighting weather proof and dust proof

Description:

LED explosion-proof lighting, which belongs to a kind of electrical equipment used in special industries, mainly solves lighting problems. It includes a lamp housing, a lamp cover disposed at the front end of the lamp housing, an illuminator and a battery disposed inside the lamp housing, and a switch disposed on the surface of the lamp housing. , which is characterized by:
The illuminant is a high-power LED module, and a wide voltage input driving circuit is arranged between the illuminant and the battery; the wide voltage input driving circuit comprises a constant current chip, the constant current chip and the battery form a power module, and the LED module is connected at a constant On the flow chip, the power module and the LED module are glued together; ultrasonic welding is performed between the lamp cover and the lamp housing.

Class II locations are those that are hazardous because of the presence of combustible dust. These environments include:

Grain elevators and bulk handling facilities
Manufacture and storage of magnesium
Manufacture and storage of starch
Fireworks manufacture and storage
Flour and feed mills
Areas for packaging and handling of pulverized sugar and cocoa
Facilities for the manufacture of magnesium and aluminum powder
Some coal preparation plants and coal handling facilities
Spice grinding plants
Confectionery manufacturing plants

The dust site is divided into three areas: 20, 21 and 22:

Zone 20: Combustible dust continuously or frequently occurs during normal operation in an amount sufficient to form a mixture of flammable dust and air and/or a location and container interior that may form an uncontrollable and extremely thick dust layer.

Zone 21: During normal operation, there may be a place where the amount of dust is sufficient to form a mixture of flammable dust and air but not zoned 20. This area includes locations directly adjacent to the charge or discharge of dust, where dust layers and flammable concentrations of flammable dust and air may be produced under normal operating conditions.

Zone 22: Under abnormal conditions, flammable dust clouds occur occasionally and are only present for a short period of time, or flammable dust occasionally accumulates or may present a dust layer and produce a flammable dust air mixture but not zoned into Zone 21. If it is not guaranteed to exclude flammable dust accumulation or dust layer, it should be divided into 21 zones.
