Shenhai Pagsabog-Patunay
Sa konteksto ng pressurized electrical equipment, Patuloy na pagsubaybay sa sistema ng proteksyon ng pressurization ay nakatayo bilang isang mahalagang hakbang sa pagpapanatili ng mga tampok ng kaligtasan na patunay ng pagsabog ng kagamitan. Ang aspeto na ito ay bumubuo ng isang pangunahing katangian ng mga pressured na de koryenteng aparato.
Ang awtomatikong aparato ng kaligtasan sa loob ng sistema ng proteksyon ng pressurization, 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 pasabog na Mga Panganib. Designers must prioritize this factor in their planning.
When integrating explosion-proof automatic safety devices, designers should follow these guidelines:
1. Para sa “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. Para sa “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.
Bukod pa rito, it’s crucial to recognize that various automatic safety devices are indispensable components of the pressurization protection system. They must consistently provide reliable
“service” bago pa man, sa panahon ng, and after the system operates. Kaya nga, the power source for these safety devices should not coincide with the main circuit. Ideal na, it should be placed before the main circuit’s switch na patunay ng pagsabog or power switch to ensure uninterrupted service, even in the event of a main circuit power outage.
