Shenhai leherketa-froga
Presiozko ekipo elektrikoen testuinguruan, Presurizazioa babesteko sistema etengabe kontrolatzea ezinbesteko urratsa da ekipoen leherketa-frogaren segurtasun-ezaugarriak mantentzeko.. Alderdi honek presiodun gailu elektrikoen ezaugarri nagusi bat osatzen du.
Presurizazioa babesteko sistemaren barruan dagoen segurtasun-gailu automatikoa, 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 lehergailua arriskuak. Designers must prioritize this factor in their planning.
When integrating explosion-proof automatic safety devices, designers should follow these guidelines:
1. Izan ere “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. Izan ere “ordenagailua” class pressurized electrical equipment, different explosion-proof classifications can be used for automatic safety devices, each corresponding to varying levels of explosion-proof protection.
Gainera, it’s crucial to recognize that various automatic safety devices are indispensable components of the pressurization protection system. They must consistently provide reliable
“service” before, during, and after the system operates. Horregatik, the power source for these safety devices should not coincide with the main circuit. Egokiena, it should be placed before the main circuit’s eztanda aurkako etengailua or power switch to ensure uninterrupted service, even in the event of a main circuit power outage.
