El 19 de novembre els alumnes de 3r A d’ESO van visitar la central hidroel\u00e8ctrica de Sant Quint\u00ed (Ripoll).<\/p>\n

El fill del propietari, en Salvador Vaquer, ens va ensenyar les instal\u00b7lacions de la central i ens va explicar la hist\u00f2ria de l’empresa i algunes curiositats sobre la generaci\u00f3 d’electricitat i la seva distribuci\u00f3. Ens va explicar que l’aigua es captava 700 metres m\u00e9s amunt amb una resclosa, es desviava per un canal i quan arribava a la central s’havia aconseguit que el salt fos de 5 metres. All\u00e0 feia girar dues turbines, connectades cadascuna d’elles a un alternador. Els dos alternadors junts tenen 250 kW de pot\u00e8ncia. Tamb\u00e9 ens va ressaltar que l’energia el\u00e8ctrica \u00e9s molt dif\u00edcil d’emmagatzemar,\u00a0 l’electricitat que es consumeix s’est\u00e0 generant en aquells moments a una central o una altra i que totes elles estan connectades a una mateixa xarxa de distribuci\u00f3.<\/p>\n

\"\"<\/a><\/p>\n

Aquesta central \u00e9s la m\u00e9s antiga del Ripoll\u00e8s (en aquell moment ja hi havia alguna f\u00e0brica que tenia alternador per\u00f2 el feien servir per consum propi). Gr\u00e0cies a ella, Ripoll va ser la quarta poblaci\u00f3 catalana que va disposar de llum el\u00e8ctrica per il\u00b7luminar els carrers.<\/p>\n

 <\/p>\n

Des de 1892, doncs, aquesta empresa ha estat subministrant energia als ripollesos. A finals dels anys 20 i fins que es va connectar a la xarxa general de distribuci\u00f3, quan tenien m\u00e9s demanda que la que podien subministrar amb el salt, engegaven un motor de vaixell que estava connectat a un tercer alternador. De vegades, fins i tot havien de trucar algun industrial perqu\u00e8 desconnect\u00e9s una estona la maquin\u00e0ria perqu\u00e8 no podien donar l’abast.<\/p>\n

El dia ens va acompanyar, va fer molt de sol, gens de fred, les explicacions d’en Salvador van interessar tothom i nom\u00e9s ens va saber greu que el grup de 3r B estiguessin confinats i no haguessin pogut venir.<\/p>\n

El dijous 3 de desembre els alumnes ens explicaran la sortida a la Veu de Sant Joan.<\/p>\n
