Explosion-proof surveillance cameras set new standards and advance with the times

China is a big producer of coal mines and petrochemicals, and it is also a country with many production accidents in such industries. In order to ensure safe production, the explosion-proof standards formulated by China are also more stringent. Wang Guangming, product manager of Tianjin Ya’an Technology Co., Ltd. stated: In terms of explosion-proof fields, China has always been at the forefront of the world, including a series of explosion-proof standards formulated by the state. The explosion-proof grades correspond to the explosion-proof grade standards of major countries in the world, and many parameters are higher than those of European and American countries; Explosion-proof product management system. '

After nearly 30 years of development of the explosion-proof industry, standards are constantly being formulated and strictly adhered to. The standard of the national standard GB3836-2000 is still widely used, but for the past two years, the frequency of safety accidents, the state of which The first, second, third, fourth, eighteenth, and nineteenth parts were revised, and the new national standard was officially implemented on August 1, 2010: GB3836-2010. Based on the original standard, the standard has formulated a more rigorous plan. After Feng Yuzhou, Sales Director of Changzhou Zoan Electric Co., Ltd. concluded, the changes in the new standard are mainly reflected in the following aspects:

· Regular inspection of the specifics: the original standard did not specify the inspection period and under what conditions the inspection was made, but the new standard made explicit requirements for this;

· Emphasizes protection against dust and water: The original standard does not require protection grades for explosion-proof products, while the new standard does detailed requirements for protection grades for explosion-proof products. At present, manufacturers use more IP67 standards that are more difficult, and IP65, some manufacturers even reached the IP68 protection level;

· Strictly auditing the qualifications of manufacturers: The original national standard's production licenses for manufacturers ("National Industrial Product Production License <Explosion Proof Electrical Appliances>", "Explosion-proof Certificates," and "Coal Mine Product Safety Certificates") are ambiguous and require manufacturers to now Obtaining production licenses, manufacturers without production licenses or incomplete licenses are absolutely not allowed to produce;

· Increased criminal liability: The original standard categorizes unlicensed operations as illegal operations, and now categorizes them as illegal operations, which has increased supervision and review efforts from the law.

According to Zhang Jun, Deputy General Manager of Changzhou Shenghe Electronics Co., Ltd., “At present, there is no uniform standard and classification for riot cameras. Explosion-proof cameras, as special industrial television equipment used in dangerous places, are strictly divided and are generally used in Mine Class I equipment and Class II equipment used in petrochemical companies. 'States and industries not only set standards for explosion-proof applications, but also clearly classify applications, strengthen supervision and management efforts, and strive to ensure the reliability of products from the source.
