The Consequences Of Not Choosing A Surge Protector Are Really Terrible!
I believe many people know about surge protectors, but many users think that surge protective device only have the function of lightning protection, and lightning strikes are low-probability events in life, so the choice of surge protection device is irrelevant. Therefore, when selecting lightning protectors for some project construction, no requirements are made, resulting in a large number of inferior lightning protectors being used in various projects, and at the same time burying major safety hazards for the operation of the power grid.
1. In 2005, an SPD caught fire at a railway station in Yingtan, Jiangxi, burning more than 1 million equipment.
2. In March 2009, a lightning protection company's product in Shishi, Fujian caught fire in the power supply of clothing factory equipment, causing nearly 1.5 million yuan of equipment damage.
3. In 2011, my country's SPDs at two communication base stations in India caught fire and suffered huge claims.
From the above cases, we can see that once the surge protector is not selected well, the subsequent electrical equipment will be directly damaged by lightning, and in severe cases, the entire distribution box will catch fire. And when the accident occurs, it will not only cause monetary losses, but also casualties. So what kind of surge protector is qualified? First of all, we need to look at the manufacturer's qualifications and certification reports, and secondly, we need to look at the cases and performance they have done, as well as whether the product's structural solution meets the requirements of the project (such as poster height, leakage current, follow-up current and other parameters).
