As soon as the explosion-proof control button shell is used, a small amount is made of cast aluminum die-casting.
Explosion-proof lighting and explosion-proof control switches, the market demand for these products is relatively large, so there are many manufacturers, mainly including lighting switches. The composite structure made of cast aluminum alloy die-casting is selected, which is simple in structure and easy to manufacture. Explosion-proof industrial and mining lamps are the main electrical appliances. The main electrical appliances are switching electrical appliances that disconnect the control circuit to announce or process. This type of explosion-proof electrical appliances mainly includes control buttons and operating columns. As soon as the explosion-proof control button shell is used, a small amount is formed by die-casting of cast aluminum. Generally, it is an increased safety shell with explosive components inside, and can achieve anti-corrosion function. It is composed of a junction box and a pillar. Some of the main junction boxes are made of one piece, and some are made of a body, each with its own characteristics. Its material is basically made of cast aluminum alloy material, and there are various instruments inside, which can be combined according to different needs.
What are the main contents of the electrical structure in the explosion-proof LED lamp cavity 1． The electrical components meet the national requirements, can withstand the temperature of the lamp cavity, provide electrical parameters that match the light source, and meet the requirements of various specific explosion-proof types of explosion-proof lamps. The planning of the structure and size of the wiring chamber must meet the specific explosion-proof functional requirements, and it should also be convenient for wiring, leaving a space suitable for the bending radius of the wire to ensure that the electrical clearance and creepage interval meet the relevant standard requirements after correct wiring, and the inner wall of the wiring chamber and normal work The inner walls of metal casings that may generate sparks must be painted with arc-resistant paint.
Since LED is a solid-state cold light source, it has the advantages of high electro-optical conversion efficiency, low heat generation, low power consumption, low operating voltage and long service life. Therefore, high-power white light LED is an explosion-proof lamp, especially a portable explosion-proof lamp. Very ambitious electric light source. There are two types of explosion-proof housings fastened with bolts for explosion-proof lighting: flat and non-stop. Regarding the plane structure, the bolts not only perform the tightening operation, but also ensure the plane space. Regarding the stop structure, when the explosion-proof surface only considers the cylinder part, the bolts only play a tightening effect; when the explosion-proof surface needs to consider the cylinder plus the plane, the bolts not only perform the tightening operation, but also ensure the empty space effect of the plane part. Care must be taken when tapping directly on the housing.
