DESCRIZIONE dell'invenzione industriale avente per titolo: CAPOCORDA CON MISURATORE DI CORRENTE DESCRIPTION of the industrial invention having as title: TERMINAL WITH CURRENT METER
RIASSUNTO SUMMARY
Campo di applicazione: impianti industriali B.T.; installazioni di uso domestico. Field of application: LV industrial plants; domestic use installations.
TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION
Entro un tubo metallico T.M. scorre un pistone P di ottone con filettatura di avanzamento al centro. Fuori asse c'è una vite di regolazione della pressione del; contatto elettrico V.C.I. Nella parte sinistra del .pistone c'è saldata una treccia di rame flessibile T.F. l'altra estremità va al punto di misura dello stru- ; mento portatile e allo stesso tempo al raccordo esterno della linea elettrica da misurare. All'estremità ; sinistra va collegato il conduttore esterno di linea tramite una vite di serraggio V.S.I. e internamente va saldata la treccia flessibile T.F. Un tubo isolante di plexiglass T.P. va inserito esternamente a quello metallico, essendo più lungo di 1 cm.di quest'ultimo .Al1'estremità destra va inserito il capocorda con vite di serraggio V.S. 3. Il perno conduttore filettato P.C. ha una rondella elastica che impedisce lo scorrimento del perno stesso. Ruotandolo si ottiene l'avanzamento del pistone di una corsa pari a 40 mm. La parte non filettata del perno attraversa l'estremità cilindrica destra, dove va inserita una manopo-, la di regolazione M.R. con rondella bloccante. La portata ottenuta varia da 1 a 100 A.sia in C.C. che in C.A. La taratura viene effettuata inserendo il capocorda in un carico R.C. costante con un amperometro sulla linea principale e un millivoltmetro ai punti di misura P.M. Il rapporto ottenuto è di 300 volte costante sia per la min. che per la max. corrente. _ A messa a punto ultimata si serrano a fondo le viti di pressione dei contatti elettrici V.S.2. e V.S.3 Within a metal tube T.M. a brass piston P with feed thread in the center slides. Off axis there is a pressure adjustment screw; electrical contact V.C.I. On the left side of the piston there is a flexible T.F. the other end goes to the measuring point of the instrument; portable and at the same time to the external connection of the electrical line to be measured. At the end; the external line conductor must be connected by means of a V.S.I. and internally the flexible T.F. An insulating tube of plexiglass T.P. it must be inserted externally to the metal one, being 1 cm longer than the latter. 3. The P.C. it has an elastic washer that prevents the pin from sliding. By rotating it, the piston advances by a stroke of 40 mm. The non-threaded part of the pin crosses the right cylindrical end, where a knob is inserted, the adjustment knob M.R. with lock washer. The flow obtained varies from 1 to 100 A. both in C.C. that in C.A. Calibration is done by inserting the cable lug into an R.C.load. constant with an ammeter on the main line and a millivoltmeter at the measuring points P.M. The ratio obtained is 300 times constant for both the min. that for the max. current. _ Once the adjustment is complete, tighten the pressure screws of the electrical contacts V.S.2. and V.S.3
