Product Details
Explosion proof lighting power distribution box for chemical plantProduct Features
1. The shell materials include cast aluminum, carbon steel, and stainless steel, which are welded using automatic protective gas welding. After welding, the surface is specially polished for a beautiful appearance, suitable for various strong corrosive environments;
2. Equipped with CN65, NC100H high breaking miniature circuit breakers, contactors, thermal relays, buttons and indicator lights, various instruments and other components, it can be used for lighting and power motor control purposes;
3. Equipped with overload and short circuit protection functions;
4. Modular structure, various circuits can be freely assembled according to needs;
5. Customized according to user requirements, such as installing electrophoresis protectors, ammeters, voltmeters, etc;
6. We can provide on-site technical services to assist users in product selection or design based on the on-site operating environment, in order to meet the requirements of national symbol standards.
7. Steel pipe or cable wiring.
When installing the explosion-proof lighting power distribution box, the cables need to be threaded through sealing rings, metal washers, and tightened with compression nuts to ensure sealing and prevent the cables from loosening. Unused wiring ports should be sealed with sealing rings and metal washers; This product is a composite explosion-proof structure. The switch box adopts an explosion-proof structure, and the busbar box and junction box adopt an increased safety structure; With the rapid development of modern heavy industry, distribution boxes are no longer able to meet the needs of modern heavy industry, resulting in what we call explosion-proof distribution boxes, explosion-proof lighting distribution boxes, and explosion-proof power distribution boxes today. Let's talk about the differences between explosion-proof lighting distribution boxes and explosion-proof power distribution boxes. Wiring methods include steel pipes, cables, and explosion-proof hoses
Explosion proof lighting power distribution box for chemical plantproduct structure
1. For the explosion-proof structure, the steel plate is welded with a shell and the surface is electrostatically sprayed with plastic;
2. Equipped with high breaking miniature circuit breakers or molded case circuit breakers, AC vacuum contactors, motor protectors, voltmeters and other components, it has overload, short circuit, undervoltage, phase loss, leakage and other protection functions.
3. Both incoming and outgoing lines are equipped with spark free explosion-proof plug-in devices and have clear equipment tag number indicator boards.
4. The explosion-proof surface adopts special processing methods, embedded with oil resistant aging silicone "0" - shaped sealing rings, to achieve a protection level of IP65 for the box body, in order to solve the problem of rainwater entering the traditional explosion-proof box for outdoor use, and to eliminate the complex and ineffective measures of traditional rainproof covers.
5. All fasteners are made of corrosion-resistant 304 stainless steel fasteners.
6. It can be installed in a hanging or vertical manner according to on-site needs.
7. Specific functions and appearance can be customized according to user requirements.
After the assembly of the explosion-proof lighting power distribution box is completed, clean the surface of the box and use foam plastic for moderate packaging to avoid damaging the box structure and surface coating during transportation and installation. Explosion proof junction boxes are generally made of cast metal. Its function is to work in an explosive gas environment. Even if there are circuit sparks inside the box or some explosive gases penetrate the box, a small-scale explosion may occur under the action of sparks. The box can withstand such situations and will not leak fire to the environment due to its weak structure or rupture, causing an explosion in the larger environment. Overcurrent protection, short circuit protection, overvoltage protection, undervoltage protection, instantaneous power outage protection, and phase failure protection. In locations with low explosion risk or far distance from the release source, consideration should be given to laying electrical circuits. For example, when the explosive gas or vapor is heavier than air, electrical circuits should be laid at high places, and cables should be directly buried underground or filled with sand in cable trenches. When the explosive gas or vapor is lighter than air, electrical circuits should be laid at a lower location, and cables should be laid in cable trenches.

Features:
1. Cast aluminum alloy shell, surface sprayed with plastic.
1. Cast aluminum alloy shell, surface sprayed with plastic.
2. The direction and specifications of the inlet can be freely selected by the user.
3. Both steel pipes and cables can be used for wiring.
4. When selecting, users should clearly specify the specifications, quantity, and orientation of the inlet and outlet lines
Gas mixture hazardous areas: Zone 1, Zone 2. 2. Gas mixture: IIA, IIB, IIC.
The product can be equipped with (main switch) plastic case circuit breakers, small circuit breakers (with overload and short circuit protection functions), AC contactors, thermal relays, signal lights, buttons, switches, and other components such as Schneider, Chint, Delixi, ABB, etc. It has reliable explosion-proof and electrical performance.
The internal wires of the explosion-proof lighting power distribution box are cold pressed with OT terminal blocks and insulated with sleeves. The terminal blocks are fastened with special anti loosening tile pads to ensure the stability and safety of electrical performance.
The switch box of this product adopts an explosion-proof structure, and the busbar box and outlet box adopt an increased safety structure; The frequency conversion speed control box for electric motors can adjust the speed of ordinary three-phase asynchronous motors by changing their output frequency, in order to meet the requirements of production processes or achieve energy-saving purposes. The energy-saving rate can reach 30%~60%. It can also be used as a soft start controller for electric motors, or as a closed-loop speed control system composed of sensors, transmitters and other control circuits. The installation and operation are simple, the starting balance has no impact current (soft start), the power capacity is greatly reduced, the power factor is constant, and it also has various functions such as fault display. As the core component of the speed control frequency converter is a single-chip microcomputer, it has strong functions. The introduction of the output direction is: upward and upward, downward and downward (which can be unrestricted according to customer requirements). The control switch has multiple specifications to choose from, and the signal light has red, green, yellow, etc. There are four types, including white, and the instrument can be optionally equipped with an ammeter, Voltage meter, temperature controller, tachometer, etc. The entry and exit lines are flexible and versatile, and can be freely selected according to user requirements, enabling on-site operation and remote control. Customized according to user requirements
Explosion proof cable reels, like other cable reels, have leakage protectors. The explosion-proof cable reel is equipped with a small leakage switch. If an accidental leakage occurs, changing the leakage protection switch will cut off the power within 0.03 seconds. At the same time, in order to prevent explosion hazards such as sparks and static electricity, all configurations of explosion-proof cable reels, including sockets, plugs, handles, etc., are made of aluminum and have undergone spray coating treatment; The pin housing and turntable are made of aluminum alloy, which is both sturdy and durable, as well as safe and reliable. The dust-proof ability can prevent trace dust from entering the equipment from affecting its normal operation, , IIA, IIB, IIC gas environment or combustible dust environment;
