6 FAQs about [Requirements for explosion-proof enclosure of wind power energy storage device]
Which applications require explosion proof equipment?
There are many applications which require explo-sion proof equipment. During the over 100 years of electrical explosion protection, principles and techniques have been developed which allow the use of electrical measuring technology, even where, for example in reaction vessels, an explosive atmos-phere is permanently present.
How safe is explosion proof equipment?
In many cases, a possible concentration ≤ 10 % of this value is con-sidered to be safe. Explosion proof equipment is able to exclude one of the preconditions for an explosion - the ignition source - and is in that way an important contribution to explosion protection.
What are explosion-proof enclosures?
Explosion-proof enclosures, also known as “IS” cabinets by Spike Electric, are designed to prevent internal explosions or fires from spreading to the surrounding area. They ensure the safety of the facility and personnel working in it.
Why is an explosion proof cabinet necessary?
In hazardous environments with explosive gas or vapor mixtures, an explosion proof cabinet is necessary to prevent dangerous pressure buildup and protect electrical equipment.
What is explosion proof/intrinsic safety?
Explosion proof/intrinsic safety are two technologies which guarantee that under no circumstances will equipment emit energy to cause an explosion. The objective of this document is to describe how to do the mechanical and electronic design for electrical/electronic equipment deployed in a hazardous environment.
Which industrial facilities use explosion proof enclosures?
Explosion-proof enclosures are used in various industrial facilities such as oil refineries, feed mills, chemical plants, plastic plants, and fireworks factories. Their primary purpose is to protect industrial equipment and devices against internal explosions.
