　　BXX explosion-proof maintenance power boxStructure and characteristics of explosion-proof maintenance socket box

This explosion-proof box is designed in accordance with GB3836.1-2000 "Electrical Equipment for Explosive Gas Atmosphere Part: General Requirements" and GB3836.2-2000 "Explosive Gas Atmosphere

Electrical equipment Part 2: Explosion proof type "d", GB3836.3-2000 "Electrical equipment for explosive gas environments Part 3: Increased safety type" e "standard equipment

Designed and manufactured, it has been inspected and approved by the national inspection agency and issued an explosion-proof certificate.

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, transformers, fuses, Ex explosion-proof control buttons, signal lights, and transfer switches. 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 explosion-proof box: The shell is welded with steel plates and sprayed with plastic on the surface.

1. The main chamber and wiring chamber are both designed with explosion-proof structures, 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 indicator 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.

2. Main technical parameter models: rated voltage (V), main circuit rated current (A), number of branches, branch rated current (A)

3. Explosion proof grade

4. The assembly method can be determined according to user requirements and designed based on the circuit diagram provided by the user.
