What are the advantages and characteristics of explosion-proof junction boxes? The explosion-proof junction box is an explosion-proof and highly sealed connector for circuit laying. From the outside, it looks like a closed box. When the cable passes through it, it enters and exits and is connected by the lock nut, thus effectively avoiding the occurrence of sparks in the connection place. And its shell is usually made of aluminum alloy, and in order to make it better fire-resistant and corrosion-resistant, its surface is often sprayed with plastic.
The junction box is composed of a box cover, a box body, terminal blocks, diodes, connecting wires, and connectors. The shell must have strong anti-aging and UV resistance, and meet the requirements of outdoor harsh environmental conditions; the self-locking function makes the connection method more convenient and firm; the terminal installation must be firm, and have good weldability with the confluence. Connectors and connecting wires: have good insulation properties, and the male and female plugs have a self-locking function, which makes the solar panel and electrical connection more convenient and reliable.
1. Explosion-proof junction box: performance characteristics
1. Explosion-proof explosion-proof grade, it can be used safely in various flammable and explosive dangerous places. High-intensity gas discharge lamp is used as light source, which has high luminous efficiency and long service life, with an average service life of more than 10,000 hours.
2. The transparent parts have been optimized and designed, the light is soft, the illumination is uniform, and there is no ghosting, which can effectively avoid eye discomfort and fatigue of construction workers.
3. The shell is made of light alloy material and treated with high-tech spraying, which is wear-resistant, anti-corrosion, waterproof and dustproof, and can be used outdoors for a long time.
4. Exquisite structural design, good heat dissipation performance, effectively reducing the temperature of the lamp body and improving the service life of the lamp. It has good electromagnetic compatibility and will not cause interference to the surrounding environment.
5. Light weight, small size, compact and beautiful, simple and convenient operation.
2. Explosion-proof junction box: wiring requirements
Customers who have used explosion-proof junction box products should know that there are binding posts inside the explosion-proof junction box, so should we use binding posts when wiring? Is the binding post necessary? Is there any wiring requirement in this regard?
Explosion-proof junction boxes are used for lighting threading connections in explosion-proof areas. Some customers will remove the internal terminals and use the internal terminals. The cables are directly wrapped with insulating tape for insulation. Generally, the terminal is used for wiring. If the terminal is used, the key is to tighten it, and the insulating tape is used instead of the post. After a winter and a summer, the insulating tape may fall off and cause a short circuit accident.
3. Explosion-proof junction box: function
Explosion-proof junction boxes are generally made of cast metal. Its function is to work in an explosive gas environment. Even if there is a circuit spark in the box, or some deflagration gas is infiltrated in the box, a small range of deflagration will occur under the action of the spark. The box can withstand this kind of situation and prevent the junction box from being damaged. The sparks caused by the internal short circuit will affect the hazardous area of the site.
