Customized explosion-proof power supply maintenance box

Customized explosion-proof power supply maintenance boxAdopting a composite and modular structure, each circuit can be freely assembled as needed. Generally, the switch box adopts a modular design, and each circuit can be freely combined Suitable for Zone 20, Zone 21, and Zone 22 environments with combustible dust; We will prepare the relevant products according to the specified time. After the user delivers the final payment, our logistics department will arrange for shipment. Please enter the detailed information The design, selection of circuits or equipment is unreasonable, without considering sufficient margin, protection level: IP65. If there is no doubt about the price between both parties, our sales personnel will organize the contract and send it to the user. After the user returns the contract and pays the advance payment, we will start production
The explosion-proof box is designed and manufactured in accordance with the standards of GB3836.1-2000 "Electrical Equipment for Sexual Gas Environments Part D: General Requirements", GB3836.2-2000 "Electrical Equipment for Sexual Gas Environments Part 2: Explosion proof Type" d "", and GB3836.3-2000 "Electrical Equipment for Sexual Gas Environments Part 3: Increased Safety Type" e "". It has been inspected and approved by the inspection authority and issued an explosion-proof certificate.

Equipped with high breaking miniature circuit breakers or molded case circuit breakers, the opening and closing can be achieved by operating the handle on the shell cover. The hazardous areas in explosive gas environments are divided, and the wire numbers are marked using a marking machine. The wire numbers are clear and complete, and attention should be paid to the wire sequence, color, and diameter. Poor contact, poor connection at the joint, poor welding, foreign objects at the joint, poor contact of switch contacts, etc. can cause excessive contact resistance at the connection, especially at copper and aluminum connection parts, which may generate dangerous temperatures. IIC grade products are equipped with explosion-proof indicator lights with special designs and AC 220/380 V universal;
A、 The shell is made of cast aluminum alloy and sprayed with plastic on the surface. The main chamber adopts an explosion-proof structure, and the wiring chamber adopts an increased safety structure. Optional components include circuit breakers, AC contactors, thermal relays, Ex explosion-proof control buttons, Ex explosion-proof signal lights, etc. The distribution box adopts a modular design, and various circuits can be freely combined. The selection of electrical components can be determined by the user, and its structure is compact and its appearance is beautiful. Both steel pipes and cables can be used for incoming and outgoing lines, and the direction of the incoming and outgoing lines can be determined by the user's requirements.
B、 Non standard distribution box: The shell is welded with steel plates and sprayed with plastic on the surface. The main chamber and wiring chamber both adopt explosion-proof structure, and can be optionally equipped with high breaking circuit breakers, AC contactors, thermal relays, control buttons, signal lights and other components. The opening and closing can be achieved through the handle on the operating shell cover, with reliable action performance and equipped with opening and closing display signal lights. Both steel pipes and cables can be used for incoming and outgoing lines, and the direction and internal components of the incoming and outgoing lines can be determined by user requirements. Other materials and shapes can be customized according to user requirements

Customized explosion-proof power supply maintenance box
Zone 1: In an environment where explosive gas mixtures may occur during normal operation, the grounding wire can be wrapped around a Φ 20-30 round rod 6-8 times to reduce its movement damage. It has overload, short circuit, phase loss, and leakage protection functions; Protection level: IP65, suitable for Zone 20, Zone 21, and Zone 22 environments with combustible dust; The shell is made of aluminum alloy die-casting and the surface is treated with high-voltage electrostatic powder spraying; Introduction port specifications: G3/4 to G11/2 "; Applicable cable outer diameter: Φ 9~Φ 28mm; Inlet direction: lower inlet, upper inlet. The outer shell is welded with 304 steel plate, and the product undergoes high-speed shot blasting treatment and high-voltage electrostatic spraying, resulting in a beautiful appearance;
