Due to their special type, many explosion-proof electrical products are not a single explosion-proof type, but a combination of two or more explosion-proof types. Such as lighting fixtures, there are explosion-proof, increased safety, and sealed types; For explosion-proof and intrinsic safety products, common ones include network base stations, signal collectors, explosion-proof and intrinsic safety power supplies (which are commonly used in coal mines), etc.

Base station products come with many communication interfaces, such asRJ45，RS232，RS485Wait, there are still some to bringPOEFor interfaces, there is a greater or lesser risk of excessive energy during use. Therefore, if pure intrinsic safety is considered, isolation measures such as adding safety barriers should be taken, which will have a certain impact on product performance. So it can be considered to use explosion-proof enclosures for protection, with all communication interfaces inside the enclosure, and signal lines led out through Zhongnuo detection explosion-proof type introduction devices, connected to gateways or acquisition devices placed in safe areas. But with the use of a flameproof casing, wireless signals cannot be transmitted, and by placing the antenna part externally and making it cost-effective, this problem can be effectively avoided.

For power products, such as explosion-proof power supplies, an explosion-proof box is added outside the power supply to mainly supply power to explosion-proof equipment. And intrinsic safety power supply ensures that the electrical sparks and thermal effects generated by the output circuit under normal operation or specified fault conditions cannot ignite, usually supplying power to intrinsically safe equipment. Explosion proof and intrinsic safety explosion-proof power supply has the characteristics of both, and meets the requirements of explosion-proof power supply and intrinsic safety Zhongnuo detection explosion-proof power supply. It is widely used in dangerous places such as mines containing flammable and explosive substances, providing stable power supply for equipment in these placesSource.
