Flame Proof Motors For Hazardous Environment JHX
troduction The use of electrical motors in potentially explosive atmospheres is quite frequent these days. These motors have to be constructed in such a way that there is no risk of an explosion. An Explosion occurs when the following situations occur: presence of potentially explosive atmosphere existence of a source of ignition possibility of transmission of the explosion Classification of Hazardous Environment: According to IS: 2, Hazardous areas are classified in the following ways depending on the degree of probability of the presence of hazardous atmosphere. Zone 2 Abnormal Conditions Presence of explosive atmosphere only by accident, but not during normal duty ( H per year) Temperature Classes: Combustible gas or vapour and explosionprotected electrical equipment are divided into temperature of the gas or to T with regard to the ignition temperature of the gas or vapour and the maximum surface temperature of the component. Temperature Ignition Maximum permitted class temperature temperature of for the gas / electrical vapour C equipment C T1 >40 40 T2 >0 <40 0 T3 >0 <0 0 T4 >13 <0 13 T >0 <13 0 T > <0 1 Flame proof motors, type "d" Zone Zone 0 Zone 1 Zone 2 Criteria presence of gas Zone 1 Occasionally cidental presence of explosive atmosphere during normal duty ( 00 H per year) Continuously of very long period Present in normal operations Zone 0 Continuously Permanent presence of explosive atmosphere ( > 00 H per year) Unlikely, but if present, only for a short time ABB motors of flame proof design (type JHX) are TEFC, 3 phase squirrel cage induction motor (as per IS:2 04) for operation in hazardous location classified as Zone 1 and Zone 2 areas as per IS:2 Note: Other frame sizes are available on request. The motor enclosure has been designed in such a way that no internal explosion can be transmitted to the explosive atmosphere surrounding the machine. The enclosure must withstand, without damage, any pressure levels caused by an internal explosion, the shape, length and gap of part assembly joints at shaft opening, cable entries, etc.., shall be designed to allow for throttling and cooling of hot gases escaping outside. The standard emphasise the impact of an explosive atmosphere (for instance, explosion pressure) over constructional requirements of such apparatus. Range:0.2... 1kW, 0.33...hp Frame:JHX1...JHX0 Pole:2... Zone 0, no electrical motors can be installed. Most common motor for Zone 1 is the flameproof design, but it can also be used in Zone 2. Application Groups: Depending on the intended use, explosionproof electrical operating equipment is divided into two major groups: Group I Group II Group II II A II B II C Equipment for coal mines (only specially designed motors for mines can be used) Electrical equipment for use other than mines (surface industry) motors with flameproof enclosures are still further divided into gas groups: Propane Ethylene Hydrogen Features: 1. Motors suitable for high ambient temperature 0ºC. 2. Keeps an explosion which takes place inside the enclosure from propagating through gaps to the ambient. 3. Withstands the explosion pressure created inside the enclosures. 4. Benefits when dealing with special operating modes such as heavy stars and special applications.. All surface temperatures are selected to comply with the temperature class.. Suitability for use in temperature classes T1 tot4.. Can be used both in Zone 1 and Zone 2.
