Ako umiestniť zásuvku v kúpeľni a pri umývadle?

Pri projekcii a následne pri revízii elektrickej inštalácie v kúpeľni sa vykonáva kontrola umiestnenia zásuviek a vypínačov v kúpeľni a v zóne podľa nasledovných podmienok: v zóne 0 sa nesmie inštalovať žiadny spínač alebo príslušenstvo, v zóne 1 sa nesmú inštalovať žiadne spínacie zariadenia ani príslušenstvo s výnimkou spínačov obvodov SELV napájaných striedavým napätím max. 12 V, alebo jednosmerným nezvlneným napätím max. 25 V. Zdroj SELV musí byť inštalovaný mimo zón 0, 1, 2, v zóne 2 sa nesmú inštalovať žiadne spínacie zariadenia, príslušenstvo so vstavanými spínačmi alebo zásuvkami. Výnimku tvoria: – spínače a zásuvky obvodov SELV (zdroj SELV je inštalovaný mimo zón 0, 1, 2), – osobitné zdroje napájania (napr. pre holiace strojčeky, fény), ktoré vyhovujú STN EN 60742, v zóne 3 sa môžu použiť zásuvky len vtedy, keď sú: napájané oddeľovacím transformátorom, napájané pomocou SELV, chránené samočinným odpojením od zdroja s použitím prúdového chrániča s citlivosťou 30 mA,…

Fotovoltická elektráreň: rady a typy

In cooperation with the daibau.sk portal, we have prepared an article in which we try to advise customers what to look out for. The full article can be found at this address: daibau.sk 1. What are photovoltaic power plants and what types are there, what does your company offer when it comes to photovoltaics? Photovoltaics in Slovakia are mainly divided according to their power output into small sources up to 10.8 kW, which are mainly intended for households and are also supported by the subsidy system Green Households. For companies and commercial entities a local source is used, this is from 10.8 to MRK. The latter is further subdivided without dispatchable control (up to 100 kW) and with dispatchable control (above 100 kW). PV is a great resource, but it needs to be properly designed. In particular, the design needs to take into account the consumption of the customer site and design it in such a way that its production also replicates consumption. In that case, it also has a very fast financial payback. Our company realizes all...

Service and maintenance of substations

Inspection and maintenance of the substation - what is to be done in the inspection and maintenance of the high voltage substation? If your company or business has a transformer station on its property, it is imperative that it is looked after and it is important that all the necessary inspection and maintenance work is carried out to ensure that it is working properly. Our company places a high value on comprehensive maintenance and inspection of all equipment to determine the exact condition and prevent breakdowns. Essential activities include: - inspection of the transformer - checking for leaks, insulators, temperature and correct setting of fuse values; - inspection of HV distribution - checking HV switchgear, accessories, fuses, section switch and other components; - inspection of LV distribution - checking low voltage switchgear, fusing, junction temperature; - checking earthing; - checking safety warnings and warning signs; - checking documentation; - checking Local Operating Regulations; - many other activities to verify the condition of the substation.
