Compared with the traditional trunking intercom technology, the biggest advantage of public network explosion-proof intercom is that it uses the mobile communication network of telecommunication operators with wide area coverage, which solves the problems of communication distance, user capacity and dedicated frequency. However, in use, due to high-frequency electromagnetic waves, radio frequency sparks can be generated, friction sparks can be generated due to friction, and ordinary public radios can explode when used, and become a source of ignition. They cannot be easily exposed to oil, gas, etc. It is used in flammable and explosive areas, but the explosion-proof public network cluster walkie-talkie has very different materials and physical characteristics from ordinary models. It is designed and produced according to the intrinsically safe electrical explosion-proof national standards.
Use of public network explosion-proof walkie-talkies
Explosion-proof public network cluster walkie-talkies cannot be used in areas that exceed the specified explosion-proof level, otherwise a safety accident may be caused because the explosion-proof level does not meet the requirements. Explosion-proof public network walkie-talkies should be used to maintain the identifiability and integrity of the signs. At the same time, the integrity of the public network walkie-talkie machine's own information signs must be ensured to determine the unique identity of the machine. It should be noted that the explosion-proof public network walkie-talkie should not be charged in an explosive gas environment, and the battery should not be replaced in an explosive gas environment. It is liable to cause a safety accident. Colleagues should not store explosion-proof public network walkie-talkies for a long time in humid and high-temperature places.
The public network explosion-proof walkie-talkie itself has a battery control circuit. Once the current is too large during charging or power supply, the fuse on the circuit board will blow in time. If the walkie-talkie is used for a long time, the circuit inside the walkie-talkie is prone to overload and short circuit, and the battery will explode due to thermal expansion. In addition, during the battery replacement process, electric sparks are also easily generated.
Explosion-proof public network walkie-talkies can be applied in oil, coal, gas and other scenarios, but not in underground mines. If there is physical damage, it is not allowed to use in explosive environment, otherwise it may cause explosion or fire.
