Description
Izolatory przepustowe, stosowane w produkcji prostowników rteciowych, musza byc odporne na dzialanie temperatury. Wskutek procesów, zachodzacych w czasie odprezania izolatorów przepustowych pod wplywem temperatury nie wszystkie z nich, jakkolwiek uprzednio zbadane i uznane jako dobre, nadaja sie do zainstalowa¬ nia w rekawach anodowych kolby prózniowej prostownika, ze wzgledu na brak wystarczajacej odpornosci na dzialanie temperatury.The bushings used in the production of mercury rectifiers must be resistant to temperature. As a result of the processes taking place during the stress relieving of bushings under the influence of temperature, not all of them, although previously tested and found to be good, are suitable for installation in the anode sleeves of the rectifier vacuum flask, due to the lack of sufficient temperature resistance.
Jak wykazala dotychczasowa praktyka wiele z tych izolatorów po zamontowaniu, w czasie formowania prostowników ulegalo peknieciu i nalezalo je wymienic.As has been shown by the previous practice, many of these insulators, after assembly, cracked during the forming of the rectifiers and had to be replaced.
Chcac uniknac dodatkowych kosztów, wynika¬ jacych tak z powtórnego zamontowania izolato¬ rów przepustowych, jak równiez z powtórnego formowania prostowników rteciowych, przed za- *) Wlasciciel patentu oswiadczyl, ze wynalaz¬ ca jest inz. Antoni Matusiak w Lodzir montowaniem na stale nalezy kazdy izolator przepustowy poddac próbie wstepnej na dziala¬ nie temperatury. Do tego celu sluzy uwidocznio¬ na schematycznie na rysunku lawa termiczna wedlug wynalazku, skladajaca sie z 6-ciu grzej¬ ników 2 o mocy 1000 W kazdy, wykonanych z drutu oporowego,'zainstalowanego w obudowie z szamotu w ksztalcie cylindra. Do wnetrza ta¬ kiego cylindra wklada sie badany izolator prze¬ pustowy 1.In order to avoid additional costs, resulting both from the reassembly of the bushings, as well as from the remodeling of mercury rectifiers, before the purchase *), the patent owner stated that the inventor is Eng. Antoni Matusiak in Lodzir, all Pre-test the bushing against temperature. For this purpose, the thermal lava according to the invention, shown schematically in the drawing, is provided, consisting of 6 heaters 2 with a power of 1000 W each, made of a resistance wire, installed in a casing made of fireclay in the shape of a cylinder. Inside the cylinder is placed the bushing to be tested 1.
Sama zasada dzialania lawy termicznej polega na tym, ze zawiera ona dwa obwody elektrycz¬ ne. Pierwszy obwód 5 — 6 — jest to obwód grzejny, zasilany z sieci pradu zmiennego 220 V i majacy na celu wytworzenie wewnatrz grzej¬ nika, w którym umieszczony jest badany izola¬ tor temperatury, zblizonej do temperatury oto¬ czenia, w jakiej izolator znajduje sie podczas normalnej pracy prostownika.The very principle of thermal lava operation is that it contains two electric circuits. The first circuit 5-6 is a heating circuit, powered from a 220 V alternating current network and intended to create, inside the heater, a temperature insulator to be tested, close to the ambient temperature in which the insulator is located. during normal operation of the charger.
Drugi obwód 7 — 8 jest to obwód pradowy, za¬ silany pradem stalym, plynacym z katody pro-atpwpljkp w czacie formowania pp£ pkclai£njeii) 1 i>r2eplywaiacyni przez Mzenie 3 izolatorów przepustowychf umieszczonych w lawie termicz¬ nej, wedlug wynalazku polaczone ze soba szere¬ gowo przy pomocy zlacz aluminiowych 4 i od¬ powiednich srub. W ten sposób przez rdzen kaz¬ dego izolatora przed jego zamocowaniem zostaje przepuszczony prad o znacznie wiekszym nate¬ zeniu (od 0 do 450 A), niz przeplywa w czase jego normalnej pracy. Izolatory przepustowe, które zdaly pomyslnie egzamin próbny, gwaran¬ tuja niezawodnosc ich uzycia podczas normal¬ nej pracy prostownika, natomiast wszystkie sla¬ be izolatory zostaja w ten sposób wykryte i od¬ dane do powtórnego odlewu.The second circuit 7-8 is a current circuit, powered by a direct current flowing from the cathode pro-atpwpljkp in the chat forming pp. Pkclaiinjeii) 1 and r2eplating through the milling of 3 bushings f placed in the thermal lava, connected according to the invention with each other in series by means of aluminum couplings 4 and the appropriate screws. In this way, a current of much greater intensity (from 0 to 450 A) than during normal operation is passed through the core of each insulator before it is fitted. Successful proofing bushings ensure that they are reliably used during normal rectifier operation, and all weak insulators are thus detected and sent for re-casting.
Z a s t r z e z ja ni e p a-vt e n t o w e Lawa termiczna do badania izolatorów prze¬ pustowych, znamienna tym, ze posiada dwa ób- wody elektryczne, z których jeden, zasilany pradram zmienfnyrjm, ^awipra grzejniki elek'try ne, sluzace do wytwarzania w otoczeniu ba¬ danych izolatorów temperatury, zblizonej do ich temperatury roboczej, natomiast drugi, zasilany pradem stalym, zawiera rdzenie badanych izo¬ latorów, przez które przepuszcza sie prad o na¬ tezeniu znacznie wiekszym od nominalnego.Thermal lava for testing bushing insulators, characterized by the fact that it has two electric water sources, one of which is powered by a variable electric current, and electric heaters for production in the environment of the tested insulators, the temperature close to their operating temperature, while the second, supplied with direct current, contains the cores of the tested insulators, through which a current of a voltage much higher than the nominal value is passed.
