2. All explosion-proof distribution box structure, electrical components assembly, circuit layout must be reliable, easy to operate, maintenance and convenient.
3. Explosion-proof distribution box should be equipped with locks and keys.
4. Explosion-proof power distribution box selection under the line and under the line, and there are outlet holes. Hole size should be based on the engineering drawings of the cable type clear, and should be equipped with a sufficient number of rubber gaskets.
5. Explosion-proof distribution box shell waterproof grade: IP65 (acid, corrosion, moisture).
6. Explosion-proof distribution box should be made of stainless steel (stainless steel material 304 or above), wall thickness of not less than 2.0mm.
7. Actual operation of the power switch, instrumentation and power outlets should be arranged in the box/cabinet of the front panel to facilitate actual operation. Socket box shell and baffle contains the door locking equipment, power socket components should have sufficient impact toughness to bear the normal start-up encountered in the external force; to take anti-corrosion measures to adapt to a wide variety of factory environment.
8. Bus ducts should be selected copper bus, bus to the outgoing terminals and rows of transmission lines should be selected copper transmission lines boxes, cabinets, screens, inside and outside the electrical conductor terminals must meet the normal operating current, the copper current-carrying level should be rated value of 1.5 times the current-carrying capacity, and can withstand not less than the cabinet electrical components of the circuit breakers to withstand the flow of electricity. The box needs to leave enough space for reasonable wiring.
9. Explosion-proof power distribution box air leakage switches and disconnect switches must meet the needs of dynamic and heat resistance.
10. Explosion-proof distribution box in the electrical equipment components should be in line with China's GB3836-2000 IEC standard design, and in the normal start-up environment to maintain the electrical clearance and creepage distance, there are other issues can go to the official website of Ruipai consulting.
