Before installing the LED lights, check that the basic technical data listed on the nameplate meets the actual conditions of use. There is an equivalent diameter φ10mm-φ14mm cable lead-in, which is introduced through the rubber sealing ring and connected to the terminal block. The cable is pressed tightly with a compression nut to seal it and prevent it from pulling out. Before use, check whether the wiring is correct and whether the fastening screws (bolts) on the housing are tightened. The cable grounding wire should be reliably grounded. Do not open the lid with power during maintenance and do not touch or damage the rubber gasket. In the course of maintenance, if there is any deterioration in the sealing ring or gasket of the induction device, it should be replaced in time to ensure the protection performance.
Cast aluminum alloy shell, exterior spray; Die-cast molding, compact layout, beautiful shape; preferred imported chips, with excellent lumen maintenance and high luminous efficiency; well-designed honeycomb light layout, the use of constant power to improve the efficiency of the lamp power , With short circuit, overvoltage protection function; drive power selection of plastic sealing technology to ensure that the components are not corrosive; carefully designed three-cavity independent layout to ensure the stable operation of various electronic components; selection of IIC explosion-proof layout, and IP66 protection grade, with excellent Explosion-proof protection function; use high borosilicate tempered glass, can withstand the impact of high energy. With main switch, overload, short circuit protection function, can be equipped with leakage protection according to user requirements; there are a variety of outlets, easy access to maintenance power; cable or pipe wiring; can be tailor-made according to user requirements. BXX52 Explosion-proof maintenance socket box installation and maintenance, socket box before installation, should check the distribution box technical parameters and use conditions are consistent. The outlet box should be reliably landed.
Energy-saving LED explosion-proof lamp in the maintenance should pay attention to what
The explosion-proof type lamp housings are generally made of metal materials, have good heat dissipation, high strength and durability, and are very popular with users. Moreover, many increased safety explosion-proof lighting components, such as lamp holders, interlock switches, etc., are also flameproof structures. An electrical device with a flameproof enclosure is called a flameproof electrical device. If the explosive gas mixture enters the flameproof enclosure and is ignited, the flameproof enclosure can withstand the explosive pressure of the internal explosive gas mixture and prevent the internal explosion from propagating to the explosive mixture around the enclosure. This is a kind of clearance explosion-proof principle, that is, a structure designed by using the metal gap to prevent the propagation of the explosion flame and cool down the temperature of the explosion product, achieve flame extinction and temperature reduction, and suppress the expansion of the explosion principle. In the AC 50Hz, voltage 380V or DC 220V, rated current to 32A line, for the use of power plug.
