Shenhai ба таркиш тобовар
Дар шароити тачхизоти электрикии фишоровар, мониторинги пайвастаи системаи муҳофизати фишор ҳамчун як қадами муҳим дар нигоҳ доштани хусусиятҳои бехатарии аз таркиш тобовар будани таҷҳизот мебошад. Ин ҷанба хусусияти асосии дастгоҳҳои электрикии фишорро ташкил медиҳад.
Дастгоҳи бехатарии автоматӣ дар дохили системаи муҳофизати фишор, 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 тарканда хатарҳо. Designers must prioritize this factor in their planning.
When integrating explosion-proof automatic safety devices, designers should follow these guidelines:
1. Барои “pb” class pressurized electrical equipment, the automatic safety device’s explosion-proof classification can utilize various types conforming to Ga “Ма” or Gb “Ма” protection levels.
2. Барои “компютер” class pressurized electrical equipment, different explosion-proof classifications can be used for automatic safety devices, each corresponding to varying levels of explosion-proof protection.
Гайр аз ин, it’s crucial to recognize that various automatic safety devices are indispensable components of the pressurization protection system. They must consistently provide reliable
“service” пеш, дар давоми, and after the system operates. Аз ин рӯ, the power source for these safety devices should not coincide with the main circuit. Идеалӣ, it should be placed before the main circuit’s гузариш ба таркиш тобовар or power switch to ensure uninterrupted service, even in the event of a main circuit power outage.
