Cache venovana nejmohutnejsim elektrickym stozarum v CR.
Cache dedicated to the biggest pylons in the Czech Republic
[CZ] Souradnice uvedene v zahlavi ukazuji na jeden ze stozaru.
Rozvodna Chodov byla vystavena jako jeden z uzlu napajecich Hlavni mesto Prahu. Pri vystavbe se pocitalo s omezenym mistem a proto je Rz Chodov zapouzdrena (s izolacnim plynem SF6). Jednim ze zajimavych momentu je fakt, ze privedeni vedeni zvlaste vysokeho napeti do rozvodny trvalo bezmala 3 roky, protoze majitel pozemku, pres ktery mela vedeni vest, si narokoval cenu takovou, jako by si na tom miste postavil hotel a ten mu 50 let vydelaval. Vysledkem bylo nejenom zpozdeni pripojeni rozvodny na okolni napetovou soustavu, ale pro nas hlavne zajimavy vznik 4 stozaru, na kterych jsou povesena vedeni 400kV z rozvoden Reporyje, Cechy Stred a Kocin a navic jeste vedeni 220kV mezi rozvodnami Cechy Stred a Milin, ktere bylo nutne prelozit na tyto stozary.
A nyni k souradnicim; ty naleznete po vypocteni nasledujici jednoduche rovnice. Informace jsou v listingu nebo na adrese: informacni brana :-)
N: N/(A*B) + C + D/(C*F)
E: [(E+360)*F-G+19*D]/(A*B)+D
A U Rz
B Us / Uf (dve desetinna)
C f
D pocet vodicu na stozaru vcetne zemnicich lan (svazek lan spojenych spojkami pocitejte jako jeden vodic)
F hranice nn
G napeti prurazove bleskojistky pro verejne pristupna mista
Dulezite upozorneni: pri hledani neni nutne vstupovat na oplocene pozemky a hlavne na stozary elektrickeho vedeni. Neznale kacery upozornuji, ze bezpecna vzdalenost od vodicu zvlaste vysokeho napeti je 4 metry!!! Pri prvnim zjisteni pokusu o zdolavani stozaru cache zrusim bez nahrady. Nejedna se o komin, kdy pri padu zabijete jenom sami sebe. Pri elektrickem vyboji (podobnem blesku), ktery vznikne jen priblizenim k vodicum, Vas to pravdepodobne nezabije hned. Budete popaleni tak na 80% tela, protoze vyboj prejde po povrchu Vasi kuze. Po padu na zem z Vas bude horici skvarek, ktery i pri rychlem zasahu zdravotniku a super kvalitni peci umre udusenim za par hodin. Kdyz budete mit stesti, tak Vas tohle nepotka, jenom se zabijete pri padu z vysky
No a ted uz konec straseni a hura na lov.
Cache vracejte na puvodni misto

[EN] The header coordinates show the one of pylons only. Chodov substation was built as one of main network nods feeding Prague. There was no place for traditional substation therefore Chodov is GIS one (isolated with SF6 gas). An interesting point is that the substation was built with no lines connected to. The connection was delayed for 3 yrs by the landlord who asked the price for the land as if he had a hotel there and planned income for 50 yrs. The output is interesting group of 4 big towers with three 400kV lines from substations Reporyje, Cechy Stred a Kocin and one 220kV line betweeen substations Cechy Stred a Milin which was necessary to hang on theese pylons.
You can find the coordinates easily after calculating the following formula. The necessary information is in the listing or on the following adress: information entrance :-)
N: N/(A*B) + C + D/(C*F)
E: [(E+360)*F-5*G+19*D]/(A*B)+D
A Substation nominal voltage
B Phase to phase voltage / Line to neutral volage (two decimal places)
C f US – 10
D number of conductors on the pylon including grounding ones (count a pack of wires connected by a coupler as the one)
F HV limit
G LV limit
Warning: do not enter enclosure, do not climb the pylons
Well... good luck.
Return the cache to the right position, please
