Steel plate explosion-proof distribution box is assembled according to electrical wiring requirements switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or screen, constitute a low-voltage distribution device. During normal operation, the circuit can be switched on or off by means of a manual or automatic switch. In the event of malfunction or abnormal operation, the circuit or alarm is cut off by means of a protective appliance. Measurement instruments can be used to display various parameters in operation, and certain electrical parameters can be adjusted to indicate or signal deviations from normal operating conditions.
Explosion-proof housing design According to the national standard GB3836-2010, explosion-proof housing structure, can be made up and down the explosion-proof cavity, a single explosion-proof cavity, can be made of quick-open door structure, explosion-proof housing can be customized according to customer drawings requirements, can also provide the required size , From my company drawings to the customer to confirm the production, the number of explosion-proof outlet of the explosion-proof enclosure, the size of the explosion-proof outlet, the explosion-proof button on the cover of the box, the number of signal lamps can be based on the customer's requirements, the observation window on the cover, also According to customer requirements size hole, the company will provide explosion-proof glass explosion-proof treatment.
Flameproof surface adopts special processing methods and is embedded with oil-resistant and aged silicone “0†shaped sealing ring, which is suitable for explosive dangerous environment such as oil exploitation, storage, chemical industry, medicine, textile, printing and dyeing, military industry and military facilities. The protection level of the cabinet is IP65, which solves the problem of using rainwater in the traditional explosion-proof box for outdoor use, and bans the traditional measures of using a rain cover to prevent rain from being complicated and invalid.
Explosion-proof mark/protection level:
ExdIIBT6 is equivalent to II2GEExdIIBT6 (European standard) IP54
ExdIICT6 is equivalent to II2GEExdIICT6 (European standard) IP54
ExeIIT6 is equivalent to II2GEExeIIT6 (European standard) IP65
Customized Explosion-proof Boxes for Welding of Steel Plates Explains the number and size of holes in the cabinet panel, the size and quantity of outlet openings, etc. The requirements must be confirmed before drawing and production can not be changed after ordering.
1. The electrical components in the steel plate explosion-proof cabinet/cabinet shall comply with the relevant regulations and maintain the electrical clearance and creepage distance under normal use conditions; the exposed live conductors and terminals in the box shall have electrical clearance and creepage distance. The impact withstand voltage or at least should comply with the relevant regulations of the electrical components directly connected to it.
2. Copper busbars shall be used for the busbars, and copper wires shall be used for the busbars to the outlet terminals and outlets. Explosion-proof boxes, cabinets and screen inner external conductor terminals must meet the normal operating current, the copper row's current carrying capacity should be more than 1.5 times the rated current capacity, and can withstand no less than the short circuit withstand current of the electrical components in the cabinet. Leave enough space for wiring.
3, steel plate explosion-proof box operation switches, meters and sockets should be arranged on the front panel of the box / cabinet, easy to operate; explosion-proof socket box shell and partitions including the door locking device, socket parts should have sufficient mechanical strength to Can withstand external forces encountered during normal use; anti-corrosion measures should be taken to suit the plant environment.
4, using the next line, under the outlet, and has a knock hole, the size of the knock hole is determined by the cable model in the drawing, and equipped with a sufficient number of rubber washers.
5, body protection rating: IP55 (anti-acid anti-corrosion waterproof).
6, using stainless steel box (stainless steel is Baosteel 304 or more), the color is stainless steel, the box thickness is not less than 2.0mm.
7. The structure of all explosion-proof steel panels, installation of electrical components, and layout of circuits must be safe, reliable, easy to operate, and easy to maintain.
9, the internal air switch, disconnector must meet the dynamic and thermal stability requirements.
10. All electrical components in the steel plate explosion-proof cabinet meet IEC309-1 and IEC309-2 and DIN EN60309, CEE17 international standards, and GB11918-2001 and GB11919-2001 standards.
