Hoewel blikseminslagen verantwoordelijk zijn voor sommige pieken, wordt het merendeel veroorzaakt door schakelhandelingen, motoren of storingen binnen het elektriciteitsnet zelf. Dat is waar een Type 2-overspanningsbeveiliging van pas komt.<\/p>\r\n<p data-start=\"632\" data-end=\"883\">Type 2 SPD's (Surge Protective Devices) worden ge\u00efnstalleerd in de hoofdverdeelkast of stroomopwaarts van UPS-systemen. Hun taak is het beperken van voorbijgaande overspanningen en het veilig omleiden van stootstromen naar aarde, waardoor uw gevoelige apparaten veilig blijven.<\/p>\r\n<p data-start=\"885\" data-end=\"1235\">In deze handleiding leggen we stap voor stap uit hoe u een Type 2-overspanningsbeveiliging installeert. Je leert de tools die je nodig hebt, veiligheidscontroles, bedradingsschema's en testmethoden. En we gaan dieper dan de meeste blogs voor beginners: we verwijzen naar de IEC 61643-normen, best practices op het gebied van bedrading en praktische technische tips die u zullen behoeden voor kostbare fouten.<\/p>\r\n\r\n<h2 data-start=\"1242\" data-end=\"1280\">Wat is een type 2 overspanningsbeveiliging?<\/h2>\r\n<p data-start=\"1281\" data-end=\"1394\">A <a href=\"https:\/\/www.britecelectric.com\/nl\/product-category\/ac-power-surge-protection\/type-2-surge-protective-device\/\" target=\"_blank\" rel=\"noopener\"><strong data-start=\"1283\" data-end=\"1297\">Type 2 SPD<\/strong> <\/a>is ontworpen om stootstromen als gevolg van indirecte blikseminslag en schakelhandelingen op te vangen.<\/p>\r\n\r\n<ul data-start=\"1396\" data-end=\"1718\">\r\n \t<li data-start=\"1396\" data-end=\"1520\">\r\n<p data-start=\"1398\" data-end=\"1520\">Waar het naartoe gaat: Ge\u00efnstalleerd in het hoofdverdeelbord (consumentenunit) of aan de ingangszijde van UPS-systemen.<\/p>\r\n<\/li>\r\n \t<li data-start=\"1521\" data-end=\"1621\">\r\n<p data-start=\"1523\" data-end=\"1621\">Waartegen het beschermt: ge\u00efnduceerde bliksemstoten, schakeltransi\u00ebnten, netstoringen.<\/p>\r\n<\/li>\r\n \t<li data-start=\"1622\" data-end=\"1718\">\r\n<p data-start=\"1624\" data-end=\"1718\">Zo werkt het: Door de stootspanning vast te zetten (Up) en energie naar de aarde af te leiden (PE).<\/p>\r\n<\/li>\r\n<\/ul>\r\n<p data-start=\"1720\" data-end=\"1762\"><strong data-start=\"1720\" data-end=\"1760\">Belangrijkste parameters gedefinieerd door IEC 61643:<\/strong><\/p>\r\n\r\n<ul data-start=\"1763\" data-end=\"2155\">\r\n \t<li data-start=\"1763\" data-end=\"1866\">\r\n<p data-start=\"1765\" data-end=\"1866\">Uc (Max Continuous Operating Voltage): De maximale RMS-spanning die de SPD continu aankan.<\/p>\r\n<\/li>\r\n \t<li data-start=\"1867\" data-end=\"1960\">\r\n<p data-start=\"1869\" data-end=\"1960\">Omhoog (Voltage Protection Level): Het klemniveau dat aan de beschermde kant blijft.<\/p>\r\n<\/li>\r\n \t<li data-start=\"1961\" data-end=\"2067\">\r\n<p data-start=\"1963\" data-end=\"2067\">In (nominale ontladingsstroom): stootstroom die de SPD herhaaldelijk kan weerstaan \u200b\u200b(golfvorm van 8\/20 \u03bcs).<\/p>\r\n<\/li>\r\n \t<li data-start=\"2068\" data-end=\"2155\">\r\n<p data-start=\"2070\" data-end=\"2155\">Imax (maximale ontladingsstroom): de grootste piek die de SPD kan overleven.<\/p>\r\n<\/li>\r\n<\/ul>\r\n<p data-start=\"2157\" data-end=\"2228\">Bijvoorbeeld die van ons bedrijf <a href=\"https:\/\/www.britecelectric.com\/nl\/product-category\/ac-power-surge-protection\/type-2-surge-protective-device\/\" target=\"_blank\" rel=\"noopener\"><strong data-start=\"2184\" data-end=\"2213\">SLP40-275\/3S+1 Type 2 SPD<\/strong><\/a> wordt gewaardeerd op:<\/p>\r\n\r\n<ul data-start=\"2229\" data-end=\"2294\">\r\n \t<li data-start=\"2229\" data-end=\"2246\">\r\n<p data-start=\"2231\" data-end=\"2246\">Uc = 275 V AC<\/p>\r\n<\/li>\r\n \t<li data-start=\"2247\" data-end=\"2261\">\r\n<p data-start=\"2249\" data-end=\"2261\">In = 20 kA<\/p>\r\n<\/li>\r\n \t<li data-start=\"2262\" data-end=\"2278\">\r\n<p data-start=\"2264\" data-end=\"2278\">Imax = 40 kA<\/p>\r\n<\/li>\r\n \t<li data-start=\"2279\" data-end=\"2294\">\r\n<p data-start=\"2281\" data-end=\"2294\">Tot \u2264 1,5 kV<\/p>\r\n<\/li>\r\n<\/ul>\r\n<p data-start=\"2296\" data-end=\"2409\">Dit maakt het ideaal voor residenti\u00eble, commerci\u00eble en industri\u00eble verdeelborden, evenals voor UPS-bescherming.<\/p>\r\n\r\n<h2 data-start=\"2416\" data-end=\"2459\">Veiligheidsmaatregelen v\u00f3\u00f3r installatie<\/h2>\r\n<p data-start=\"2460\" data-end=\"2553\">Het installeren van een SPD betekent werken in een live distributiepaneel.

Door de juiste installatieregels te volgen (korte bedrading, juiste geleiderdoorsnede, betrouwbare aarding en back-upbescherming) zorgt u ervoor dat uw SPD precies presteert zoals ontworpen.<\/p>\r\n<p data-start=\"8451\" data-end=\"8610\">Een UPS alleen is niet voldoende om gevoelige systemen te beschermen. Door hem te koppelen aan een correct ge\u00efnstalleerde Type 2 SPD, krijgt u de veerkracht waar moderne faciliteiten om vragen.<\/p>\r\n<p data-start=\"8612\" data-end=\"8947\">De SPD's uit de SLP40-275\/3S+1- en BR-30FU-serie van ons bedrijf zijn ontworpen voor eenvoudige installatie op DIN-rail, ingebouwde veiligheidsvoorzieningen en naleving van de IEC 61643-normen. Of u nu een woonbord, een commercieel kantoor of een industrieel UPS-systeem beschermt, deze oplossingen zorgen voor betrouwbaarheid en gemoedsrust op de lange termijn.<\/p>","protected":false},"featured_media":2158,"parent":0,"menu_order":123,"template":"","meta":{"_acf_changed":false},"blog_category":[8],"class_list":["post-2171","blog","type-blog","status-publish","has-post-thumbnail","hentry","blog_category-company-news"],"acf":{"des":"This guide explains how to install a Type 2 surge protector step by step, with wiring diagrams, safety checks, and IEC-compliant best practices.
