As an electrical product, no matter what the application, the main assessment index is how the electrical performance, especially explosion-proof electrical products, due to its structural particularity, so its higher electrical performance requirements. There are many companies that tend to focus only on explosion-proof structures and neglect electrical performance indicators. This is dangerous. In China, there have been many accidents caused by poor electrical performance, which led to arc short circuit, burned through the steel shell or caused damage to the shell. The end result of these accidents was caused by poor electrical performance. The electrical performance of explosion-proof electrical products should be given enough attention in the following aspects.
Explosion-proof electrical appliances its most important assessment indicator is how electrical performance
At present, explosion-proof electrical products sold on the market do not go down to dozens or even hundreds, and for so many product manufacturers, there are not many manufacturers that can come up with a complete design file for a certain product. Explosion-proof electrical products are related to people's lives and property safety, and product design work is the basis of explosion-proof electrical products. Some of our manufacturing plants need not be designed, and even the most basic explosion-proof knowledge and requirements are not understood, and manufacturing is started. Needless to say, product tests, product drawings, and documents. Some manufacturers often buy a prototype, make products according to the painting and scoop, put it on the market, as product standards, drawings, explosion-proof certificate, test report, etc. simply do not. If it is really needed, it should be dealt with by means of copying, fraudulent use, and borrowing. This product is definitely not qualified. As the manufacture of explosion-proof electrical products, there is a complete production system, which will never be reduced due to the entry into the market economy. It is only in the market economy that these tasks are done faster and in less time. Some companies use their nameplates or use other manufacturers' products to use their own nameplates. The reason for this is that they do not have the technical ability to do basic guarantees and cannot meet the basic requirements for the production of explosion-proof electrical products. The temptation of interest is quite risky. Some companies neglected to understand the integrity of product design data, and other product files were incomplete, improper use of technical personnel or simply no technical management personnel, leaving the product with many problems. To give a simple example: The product specification and product are marked with explosion-proof rating IIBT6, while the product standards and test reports, product certificate of conformity is marked as IIBT4. Errors like this can be seen everywhere. Other products found problems in the tests, but they were temporarily processed and the problems still existed in production.
