Scope of application of explosion-proof distribution box
1. Applicable to hazardous locations in Zone 1 and Zone 2 of explosive gas environments.
2. Suitable for Class IIA and IIB explosive gas environments.
3. Applicable to areas 21 and 22 with combustible dust environment.
4. Widely used in dangerous environments such as oil exploration, oil refining, chemical industry, and military industry, as well as offshore oil platforms, tankers and other places
Explosion-proof distribution box product features
1. This product has an explosion-proof structure, a steel plate welded shell, and the surface is electrostatically sprayed;
2. Built-in high-breaking small circuit breaker or molded case circuit breaker, AC vacuum contactor, motor protector, voltmeter and other components, with overload, short circuit, undervoltage, phase loss, leakage and other protection functions.
3. Both incoming and outgoing lines adopt non-sparking explosion-proof plug-in devices, and have clear equipment number indication boards. The indicator boards are bent and formed from 304 stainless steel plates, polished, and the appearance is beautiful, generous and practical.
4. The explosion-proof surface adopts special processing methods and is embedded with an oil-resistant and aging silicone "0"-shaped sealing ring, so that the protection level of the box reaches IP65. This solves the problem of rainwater entering the traditional explosion-proof box when used outdoors, and eliminates the traditional use of rainproof covers to prevent the explosion. Rain complicated and ineffective measures.
5. All fasteners are made of 304 stainless steel fasteners that are resistant to strong corrosion.
6. Specific functions and appearance can be customized according to user requirements.
Explosion-proof distribution box ordering instructions
When ordering, the user must indicate the number of circuits, circuit current and poles of the circuit breaker of the distribution box. If it is equipped with a main switch, the switching current and number of poles must be indicated, as well as the direction, quantity and size of the inlet and outlet. If lighting, power, leakage, etc. are mixed, a schematic diagram must be provided.
How to use explosion-proof distribution box
1. According to the actual lighting needs of the work site, determine the installation location and method of the lamp, and then prepare a three-core cable of corresponding length according to the distance between the lamp and the 220V power contact (if steel pipe wiring is used, introduce the three-core cable into the steel pipe to Lighting installation location).
2. First remove the fixing screws on the wiring cavity, pull out the wiring part of the wiring box; take out the sealing ring and connector (with set screws) from the packaging box, and insert the cables in sequence; then connect one end of the three-core cable respectively After accessing the "L", "N" and grounding points in the box, use a cable clamp to compress the cable and fix it with fastening screws. Then tighten the connector, tighten the sealing ring, and tighten the fastening screw from the side.
3. Screw the components in step 2 into the steel pipe, install the set screws from the side and lock them, then install the lamp body along the guide rail of the junction box, and then tighten the screws on the panel.
4. Finally, connect the other end of the three-core cable to the 220V power supply according to the requirements of the explosion-proof distribution box.
5. When replacing the light bulb, first cut off the power supply, then use an Allen wrench to remove the set screw on the casing, use a large screwdriver or other tool to loosen the lamp cover 6 turns, then carefully remove the lamp cover slowly by hand, and unscrew the lamp cover. Remove the old light bulb and replace it with a new one.
6. The shell of the explosion-proof lighting distribution box is made of high-quality aluminum alloy. It is equipped with a high-breaking small circuit breaker or molded case circuit breaker, a power indicator light and terminal blocks; the circuit breaker is equipped with an operating handle externally, which is flexible in operation and has reliable explosion-proof performance; for outdoor use A rain cover or protective cabinet can be installed.
Our main products are: Electromagnetic flowmeter, Energy meter, Vortex flowmeter, Pressure transmitters, Level gauge, Magnetic flap level gauge.
