| Protection level of terminal blocks Add Time：2022/03/14 |
|
| With the beginning of our country 3C approval, the national security of electrical products, electromagnetic compatibility requirements proposed higher requirements, which relates to the safe project mainly include: mechanical structure, shell protection, insulation, heating, fire test, shock proof, safety signs and safety instructions. Mechanical safety requirements of terminals in the moving parts of the chemical and structural materials and charged to ensure personal safety, such as edges and corners of the shell, metal burrs, and parts of the connecting strength, even in movement under the condition of the stability of the products, above all is pair of terminals required mechanical structure for electric power industry. Protection requirements of the shell is mainly for the protection of the provisions, it is mainly divided into two sides, one is the solid foreign body protection level, another is the water damage to the equipment and products. Insulation requirements mainly according to the materials, working voltage and environmental pollution level, selecting reasonable electrical clearance and creep age distance, so as to protect the safety of staff and work product, and make the product will not occur insulation damage in over voltage. | |
