The principle of intrinsically safe explosion-proof technology
Intrinsically safe explosion-proof technology is actually a low-power design technology. For example, for hydrogen (IIC) environment, the circuit power must be limited to about 1.3W. It can be seen that intrinsically safe technology can be well applied to industrial automation instruments. In view of the fact that electric spark and thermal effect are the main detonation sources of explosive dangerous gas explosion, intrinsically safe technology realizes explosion protection by limiting the two possible detonation sources of electric spark and thermal effect.
Under normal working and fault conditions, when the energy of the electric spark or thermal effect generated by the instrument is less than a certain level, it is impossible for the low-altitude meter to ignite the explosive dangerous gas and cause an explosion. It is actually a low power design technique. The principle is to start with the limitation of energy, and reliably limit the voltage and current in the circuit within an allowable range, so as to ensure that the electric spark and thermal effect generated by the instrument will not Causes an explosion of hazardous gases that may be present in its surroundings. Usually for the hydrogen environment, which is the most dangerous and explosive environment, the power must be limited to less than 1.3W. The International Electrotechnical Commission (IEC) stipulates that only Ex ia level intrinsically safe explosion-proof technology can be used in zone 0, the most dangerous hazardous location. Therefore, intrinsically safe explosion-proof technology is the safest, most reliable, and most widely applicable explosion-proof technology. Intrinsically safe instrumentation equipment can be divided into Ex ia and Ex ib according to the degree of safety and the place of use. The explosion protection level of Ex ia is higher than that of Ex ib.
Ex ia level intrinsically safe instruments will not explode in circuit components under normal working conditions and when there are two faults in the circuit. In type ia circuits, the operating current is limited to less than 100mA, which is suitable for zone 0, zone 1 and zone 2.
Ex ib level intrinsically safe instrument is under normal working condition and when there is a fault in the circuit, the circuit components will not ignite and explode. In type ib circuits, the operating current is limited to less than 150mA, which is suitable for zone 1 and zone 2.
