<\/figure><\/div>\n\n\n\nSet\u0103rile firului de \u00eemp\u0103m\u00e2ntare pentru echipamentele electrice trebuie tratate diferit \u00een func\u021bie de diferitele zone periculoase \u0219i tipuri de echipamente electrice. Carcasele metalice ale tuturor echipamentelor electrice din medii explozive, indiferent dac\u0103 sunt instalate sau nu pe structuri metalice \u00eemp\u0103m\u00e2ntate, trebuie s\u0103 fie \u00eemp\u0103m\u00e2ntate. Cerin\u021bele relevante sunt urm\u0103toarele: <\/p>\n\n\n\n
1) Tuturor echipamentelor electrice din mediul exploziv Zona 1, Zona 20 \u0219i Zona 21, precum \u0219i tuturor echipamentelor electrice, cu excep\u021bia corpurilor de iluminat din mediul exploziv Zona 2 \u0219i Zona 22, trebuie s\u0103 li se adauge fire dedicate de \u00eemp\u0103m\u00e2ntare. Not\u0103: Dac\u0103 firul de \u00eemp\u0103m\u00e2ntare dedicat este pus \u00een aceea\u0219i conduct\u0103 de protec\u021bie ca \u0219i firul de faz\u0103, acesta trebuie s\u0103 aib\u0103 acela\u0219i nivel de izola\u021bie ca \u0219i firul de faz\u0103. <\/p>\n\n\n\n
2) Pentru corpurile de iluminat din mediul exploziv Zona 2 \u0219i Zona 22, un sistem fiabil de conducte metalice de conectare electric\u0103 poate fi utilizat ca fir de \u00eemp\u0103m\u00e2ntare, dar conductele pentru transportul substan\u021belor periculoase explozive nu pot fi utilizate. <\/p>\n\n\n\n
3) Firele de \u00eemp\u0103m\u00e2ntare dedicate pentru echipamentele electrice \u0219i corpurile de iluminat trebuie s\u0103 fie conectate separat la re\u021beaua principal\u0103 de \u00eemp\u0103m\u00e2ntare (re\u021bea), iar firul neutru de lucru din circuitul electric nu trebuie utilizat ca fir de \u00eemp\u0103m\u00e2ntare de protec\u021bie. <\/p>\n\n\n\n
4) Conexiunea dintre echipamentele electrice din medii cu pericol de explozie \u0219i firul de \u00eemp\u0103m\u00e2ntare ar trebui s\u0103 utilizeze de preferin\u021b\u0103 fire flexibile cu mai multe toroane, cu suprafa\u021ba minim\u0103 a sec\u021biunii transversale a firului de cupru nu mai mic\u0103 de 4 mm\u00b2. Tuburile de protec\u021bie ar trebui s\u0103 fie instalate la p\u0103r\u021bile predispuse la deterior\u0103ri mecanice. <\/p>\n\n\n\n
5) Atunci c\u00e2nd cablurile blindate sunt introduse \u00een echipamentele electrice, firul de \u00eemp\u0103m\u00e2ntare trebuie conectat la \u0219urubul de \u00eemp\u0103m\u00e2ntare din interiorul echipamentului; banda de o\u021bel \u0219i carcasa metalic\u0103 trebuie conectate la \u0219urubul de \u00eemp\u0103m\u00e2ntare extern\u0103 a echipamentului. <\/p>\n\n\n\n
6) \u0218uruburile utilizate pentru \u00eemp\u0103m\u00e2ntare sau conexiune zero \u00een medii explozive periculoase trebuie s\u0103 aib\u0103 dispozitive antitensionare; \u00eenainte de str\u00e2ngerea firului de \u00eemp\u0103m\u00e2ntare, terminalele de \u00eemp\u0103m\u00e2ntare \u0219i elementele de fixare trebuie acoperite cu unsoare de putere. <\/p>\n\n\n\n
Exist\u0103 multe cerin\u021be de \u00eemp\u0103m\u00e2ntare pentru echipamentele electrice din medii cu pericol de explozie. \u00cen procesul de proiectare \u0219i instalare, pe l\u00e2ng\u0103 \u00eendeplinirea cerin\u021belor de mai sus, trebuie respectate \u0219i standardele relevante.<\/p>","protected":false},"excerpt":{"rendered":"
