1.The explosion-proof power distribution box is a low-voltage power distribution device that assembles switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on the screen according to the electrical wiring requirements. During normal operation, the circuit can be switched on or off by means of manual or automatic switches. In the event of failure or abnormal operation, the circuit can be cut off or alarmed by means of protective appliances. By means of measuring instruments, various parameters in operation can be displayed, and some electrical parameters can also be adjusted to prompt or send signals for deviations from the normal working state. It is often used in various hair, distribution and substations.
2. Purpose of explosion-proof distribution box: Reasonable distribution of electric energy, convenient opening and closing of circuits. It has a high safety protection level and can visually display the conduction state of the circuit. It is easy to manage, and it is helpful for maintenance when a circuit failure occurs.
3. With the rapid development of petroleum, chemical, mining and other industries, distribution boxes are more and more widely used, and there are more and more varieties. How to prevent the accidental explosion of the distribution box in the explosive gas dangerous place has become a very important issue. Since electrical sparks are inevitably generated by the distribution box during work, once they meet the explosive gas mixture in the place, it will lead to an explosion accident, directly endangering the safety of national property and citizens' lives.
