eksplosionssikre lamper Omgivelsestemperatur refererer til temperaturen i luften eller et andet medium, der omgiver udstyret eller komponenten.<\/p>\n\n\n\n

\"\"<\/a><\/figure><\/div>\n\n\n\n

Under normale omst\u00e6ndigheder b\u00f8r omgivelsestemperaturen for udstyrets drift v\u00e6re -20 til 40 \u2103. I s\u00e5danne tilf\u00e6lde er der ikke behov for yderligere m\u00e6rkning af omgivelsestemperaturen. Men n\u00e5r udstyret forventes at blive brugt i et milj\u00f8 uden for dette temperaturomr\u00e5de, betragtes det som en s\u00e6rlig situation. M\u00e6rkningen skal omfatte symbolet Ta eller Tamb sammen med de \u00f8vre og nedre gr\u00e6nser for den omgivende temperatur. Hvis dette ikke er muligt, skal symbolet \u201cX\u201d angive de s\u00e6rlige driftsbetingelser, herunder de \u00f8vre og nedre gr\u00e6nser for omgivelsestemperaturen. Det betyder, at kravet til omgivelsestemperatur p\u00e5 -20 til 40 \u00b0C for udstyr typisk ikke beh\u00f8ver at blive markeret p\u00e5 typeskiltet eller det eksplosionssikre certifikat. Men hvis udstyret er beregnet til brug i et andet omgivelsestemperaturomr\u00e5de end dette, skal det markeres p\u00e5 produktets typeskilt og certifikat og specificeres i brugervejledningen.<\/p>\n\n\n\n

Hvad er de s\u00e6rlige krav til omgivelsestemperatur for brandsikkert elektrisk udstyr og eksplosionssikre lamper?<\/p>\n\n\n\n

For det f\u00f8rste har lav temperatur en indvirkning p\u00e5 eksplosionstrykket, og de tilsvarende regler er:<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

N\u00e5r omgivelsestemperaturen er under -20 \u00b0C, skal referencetrykket m\u00e5les ved lavtemperatur- eller fortryksmetoder. Det referencetryk, der opn\u00e5s p\u00e5 denne m\u00e5de, er meget h\u00f8jere end det, der m\u00e5les under normal temperatur og tryk. <\/p>\n\n\n\n

Derfor er styrkekravene til indkapslinger af elektrisk udstyr i lavtemperaturmilj\u00f8er h\u00f8jere, og det skal der tages h\u00f8jde for under designprocessen.<\/p>\n\n\n\n

For det andet indflydelsen af h\u00f8j temperatur p\u00e5 den interne ant\u00e6ndelses-ikke-spredningstest og de tilsvarende regler:<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Det vil sige, at n\u00e5r omgivelsestemperaturen er h\u00f8jere end 60 \u2103, skal den interne ant\u00e6ndelses-ikke-forplantningstest udf\u00f8res ved hj\u00e6lp af h\u00f8j temperatur eller fortryk. Eksplosionstrykket, der genereres p\u00e5 denne m\u00e5de, er st\u00f8rre end det under normal temperatur og tryk. <\/p>\n\n\n\n

Udstyr, der kan best\u00e5 testen under normal temperatur og tryk, kan muligvis ikke best\u00e5 testen for intern ant\u00e6ndelse uden spredning under fortryk. Det stiller h\u00f8jere krav til l\u00e6ngden, mellemrummet og styrken af den flammesikre samlingsoverflade p\u00e5 flammesikkert udstyr, der bruges i h\u00f8jtemperaturmilj\u00f8er. Disse faktorer b\u00f8r tages i betragtning under designprocessen.<\/p>","protected":false},"excerpt":{"rendered":"
