Explosion -proof electrical appliances are a type of electrical equipment used in places with explosive dangerous gases and vapor.Chemical production often encounters various gases and vapor with explosive danger. Where there are these media, in accordance with relevant specifications, standards, and regulations, the appropriate explosion -proof appliances are correctly selected to prevent the surrounding explosive mixture explosion.It is an important measure to ensure safe production, prevent explosion and fire.There are usually necessary explosion -proof signs and technical data on explosion -proof electrical appliances to avoid wrong use.
Explosion -proof electrical model
Explosion -proof electrical models include BAD series, BAX explosion -proof ceiling lights, BayD explosion -proof emergency lights, BAT explosion -proof lamps, Bay56 explosion -proof anti -corrosion full -plastic fluorescent lights, etc.
Principles of explosion -proof electrical appliances
Both explosion -proof electrical appliances must use the wiring box and the main body of the device for electrical connection wiring box is a component for connecting cables or wires to connect to electrical equipment.Class I explosion -type electrical equipment is widely used in explosion -type wiring.The inner wall of the box wiring box should be coated with arc paint, and the explosion -proof coatings on the wiring box and the main cavity should be processed, such as coating rust oil.
Types of explosion -proof electrical appliances
I. The types of explosion -proof control box mainly include the lighting distribution box for controlling the lighting system and the power box for controlling the power system.Most of these products are combined and can control up to 12 circuits. Most of their shells are made of cast aluminum alloy materials, and some are welded with steel plates, and a small part of the insulating material shell.It is mainly composed of components such as circuit breakers, contactors, heat relays, conversion switches, signal lights, buttons and other components. The manufacturer can also be equipped according to user needs.The highest explosion -proof level can reach the highest ⅡCT6 level.By the way, explosion -proof automatic switch, explosion -proof knife switch, and fuses are often used as control power or lighting power distribution systems in some control occasions, but it is just a single piece.Therefore, these products are also placed in such products.Second, explosion -proof startups include manual startups, electromagnetic starters, reversible electromagnetic bootors, auto -coupled pressure hyperthyde, Y — △ transform reduction boosts and feedback switches.As a terminal control device, explosion -proof starter products are generally controlled by a starter to control an electric motor, which is a large -scale large -scale wide -ranging product.Its shell is usually made of aluminum alloy or steel plate.It is generally composed of an contactor (air or vacuum), electric motor protection system, signal lights, buttons, and auto -coupled transformers, and — also has local control, long -distance control and automatic control functions.Some products are installed with circuit breakers as general switches to make the product more complete.
