The use of non-explosion-proof electrical equipment is an important factor in the causes of petrochemical accidents. For example, non-explosion-proof electrical switches are prone to sparks when they are opened or closed, which provides a source of ignition for the deflagration of the volatile gas of the cleaning agent, and provides a source of ignition for fire and explosion. Accidents create hidden dangers. Therefore, explosion-proof electrical equipment has become the equipment that petrochemical enterprises must focus on purchasing every year. In fact, there are many similar high-risk environments around us. In order to ensure normal work and improve work efficiency, walkie-talkies are usually used. So what environment needs to use explosion-proof intercom?
1. What is an explosion-proof intercom?
Explosion-proof intercoms refer to walkie-talkies that can work in explosive gas environments. Unlike civilian walkie-talkies, explosion-proof intercoms do not refer to intrinsically safe walkie talkie that can resist explosions themselves, but to walkie-talkies that can work in explosive gas environments. The appearance of explosion-proof intercoms is no different from ordinary walkie-talkies, but the materials and physical properties used are very different from ordinary models. It is suitable for environments with harsh environments and dangerous flammable gas or dust such as petrochemical, coal mine, chemical, thermal power, food processing and other industries.
We know that walkie-talkies rely on electromagnetic waves to transmit signals, and the transmission of electromagnetic waves relies on the continuous conversion of electric and magnetic fields, and sparks are easily generated during this conversion process. The explosion proof walkie talkie has been shielded where sparks may be generated during the conversion process because its lines are specially treated. Explosion-proof explanations are suitable for environments with harsh environments and dangerous flammable gases or dust, such as petrochemical, coal mine, chemical, thermal power, food processing and other industries.
2. What environment needs to use explosion-proof intercoms?
Everyone knows that in the production, transportation and storage of fuel or chemicals, chemical plants, oil tanker holds, gas stations, flour mills, flax mills and coal mills and other hazardous areas of operation with a large amount of combustible dust, safety is the most important, generally these places are prohibited from using mobile phones, because the mobile phone will generate electric sparks during the communication process, which may cause an explosion. In the above environment, in order to ensure normal work and improve work efficiency, what communication tools do staff use to communicate more safely? Use walkie-talkies, but not ordinary walkie-talkies, but professional explosion-proof intercoms.
