Human beings pay attention to health, products pay attention to environmental protection, now the distribution box products also pay more and more attention to environmental protection.Waterproof distribution box design into environmental protection elements is a development trend of new distribution box, waterproof distribution box environmental protection from the coating.
outdoor abs waterproof Distribution box itself is not harmful to human body, and the coating in the distribution box panel is likely to be harmful to human body.Environmental protection distribution box is from the coating, the good environmental protection of the first pass, with RTV antifouling flash coating, the coating surface between the force of water molecules is less than the water molecules themselves direct cohesion, is water on the SURFACE of RTV presents isolated water droplets, it is difficult to form a continuous water film - this is hydrophobic, when the RTV surface accumulation of pollution,The free hydrophobic group of RTV diffused to the dirty layer and formed hydrophobic and hydrophobic migration characteristics on the dirty surface.
outdoor abs waterproof Distribution box when RTV coating by long-term immersion or rain erosion, coating hydrophobicity temporarily weakened or disappeared, natural dry placed for a period of time, RTV internal hydrophobicity group and gradually spread outward, the surface hydrophobicity and gradually restore - hydrophobicity.RTV coating surface hydrophobic groups and RTV coating all hydrophobic groups in the number of comparison is very small, RTV hydrophobic life is very long, this coating on the waterproof distribution box itself also plays a certain protective role, can prolong the service life of the waterproof distribution box.
Distribution box cleaning and maintenance requirements and methods:
1, distribution box wiring insulation copper wire should not be less than 4mm2, RS485 loop wire should not be less than 0.5mm2.
2, the distribution box should use insulation flame retardant wire, color code should be: phase line for yellow, green and red; The null line is black; The PE line is yellow and green.
3. Auxiliary terminals for collectors should be configured in the incoming switch room of the distribution box.
4, the distribution box is also used in the trough wiring, the inlet and outlet lines are separated independently, the wiring design is reasonable, the process is passed.
5. Each distribution box location shall be numbered, and "property right demarcation point" shall be marked on the entrance line at the outlet end of the meter.
6. The creepage distance of the incoming unit of the distribution box is greater than 12mm, the electrical interval is greater than 10mm, and the creepage distance of the outgoing unit is greater than 8mm.
