What is called explosion-proof electrical equipment: A type of electrical equipment used in places where there is a risk of explosion of gases and vapours. Chemical production often encounters various gases and vapours that are dangerous to explode. In places where these media are present, proper explosion-proof electrical appliances (explosion-proof electrical apparatus) are properly selected in accordance with relevant regulations, standards, and regulations, so as to prevent the explosion of surrounding explosive mixtures. . It is an important measure to ensure safe production, prevent explosions and fires. Explosion-proof signs and technical data are usually necessary on explosion-proof appliances to avoid misuse.
Explosion-proof electrical appliances are mainly divided into: explosion-proof lighting, explosion-proof electrical equipment, explosion-proof pipe fittings, explosion-proof anti-corrosion electrical equipment, dust explosion-proof electrical appliances, stainless steel explosion-proof electrical appliances.
Explosion-proof electrical appliances are mainly divided into the following categories (excluding explosion-proof lighting appliances):
Explosion-proof control switch
The market demand for this type of product is relatively large, so the manufacturer is also more, mainly including the lighting switch, transfer switch (combination switch), limit switch, pull switch and other small explosion-proof products. The explosion-proof grades of these products can reach IICT6 level. The explosion-proof housing shell is usually a composite structure made of cast aluminum alloy die-casting, and a few manufacturers use other material shells. These products are characterized by their small size, single internal components, low technological content, simple structure, and easy fabrication.
Explosion-proof main controller
A master device is a switching device that is used to close or open a control circuit to issue a command or program control. Such explosion-proof electrical appliances mainly include control buttons and operating columns. Explosion-proof control button housing is generally made of polycarbonate, glass fiber reinforced unsaturated polyester resin or ABS plastic injection molding, and a small amount is cast aluminum die casting. The general structure is an increase-safety enclosure with flame-proof components. It can also achieve anti-corrosion function and the explosion-proof grade can reach Class IIC. The operating column is mainly composed of a main tank, a junction box and a pillar. Its main box and junction box are made into one body, and some are made into separate bodies, each with its own characteristics. Its material is basically made of cast aluminum alloy material. The interior consists of various instruments, switches, buttons, and signal lights. Can be combined according to different needs.
Explosion-proof starter <br> <br> Such products include manual starter, explosion-proof electromagnetic starter reversible magnetic starters, auto decompression starter, Y-Δ conversion and the feed voltage starter switch, and other products. Explosion-proof starter products as terminal control equipment, generally a starter to control a motor, belonging to a wide range of products. Its casing shell is usually made of cast aluminum alloy or steel plate. The inside is generally composed of contactors (air or vacuum type), motor protection systems, signal lights, buttons and auto-transformation OS and other components, and generally have local control, remote control and automatic control functions. In some products, circuit breakers are installed as master switches to make the products more perfect.
Explosion-proof junction box
In use, electrical equipment must be connected to a power supply network via wires or cables to form a system to perform its functions. However, the connecting wire or cable cannot be infinitely long, and there are many places in the connection process that require wire tapping in series and in parallel. This will inevitably cause external filtration of the joint part, which will easily lead to accidents. Explosion-proof junction box products are products that are manufactured to solve such problems in order to further ensure safe production. Such products include junction boxes, junction boxes, thread boxes, hanging boxes, distribution boxes and other products, and its shell is mainly made of cast aluminum alloy. According to requirements, there are a lot of incoming and outgoing lead-in devices, and the boxes are equipped with connecting terminals for connecting or tapping. Most of these products are made of flameproof or increased safety, the volume some small, quite different, explosion-proof grade up to grade â…¡C <br> <br> proof control box (explosion-proof distribution box)
It mainly consists of a lighting distribution box for controlling the lighting system and a power box for controlling the power system. Most of these products are modular and can control up to 12 circuits. Most of their shells are made of cast aluminum alloys. Some of them are welded by steel plates, and a few are insulated. Its internal main circuit breakers, contactors, thermal relays. The switch, signal light, button and other components constitute the manufacturer can also choose to deploy the user needs. Explosion-proof grade up to IICT6 level. Incidentally, explosion-proof automatic switches, explosion-proof knife switches, and fuses are also often used as control power or lighting distribution systems in some control applications, but only as a single piece. Therefore, these products are also classified as such products.
