Shenhai rezistent la explozie
În contextul echipamentelor electrice sub presiune, monitorizarea continuă a sistemului de protecție împotriva presiunii reprezintă un pas vital în menținerea caracteristicilor de siguranță anti-explozie ale echipamentului. Acest aspect formează o caracteristică cheie a dispozitivelor electrice sub presiune.
Dispozitivul automat de siguranță din cadrul sistemului de protecție împotriva presiunii, tasked with monitoring and managing the system’s operational status, must not become an ignition source for combustible gases. It should either meet specific explosion-proof standards or be located in areas free from exploziv pericole. Designers must prioritize this factor in their planning.
When integrating explosion-proof automatic safety devices, designers should follow these guidelines:
1. Pentru „pb” class pressurized electrical equipment, the automatic safety device’s explosion-proof classification can utilize various types conforming to Ga „Ma” or Gb „Ma” protection levels.
2. Pentru „pc” class pressurized electrical equipment, different explosion-proof classifications can be used for automatic safety devices, each corresponding to varying levels of explosion-proof protection.
în plus, it’s crucial to recognize that various automatic safety devices are indispensable components of the pressurization protection system. They must consistently provide reliable
„service” înainte, în timpul, and after the system operates. Prin urmare, the power source for these safety devices should not coincide with the main circuit. Ideal, it should be placed before the main circuit’s comutator antiexplozie or power switch to ensure uninterrupted service, even in the event of a main circuit power outage.
