zamykanie załącznika zwarciowego Explanation: Czasopismo Przegląd Elektrotechniczny Tytuł artykułu Badanie dynamiki ruchu styków załącznika zwarciowego EN Analysis of the movement dynamics of contacts and contact- set of the making switches > PL W artykule przedstawiono analizę charakterystyk dynamicznych ruchu styku ruchomego podczas zamykania szybkiego łącznika wysokiego napięcia, przy zastosowaniu technik poprawy pracy łącznika. Celem badań było ustalenie wpływu istotnych cech konstrukcyjnych układu stykowego załącznika zwarciowego, na proces niejednoczesności łączenia styczek oraz na wartość czasu zamykania łącznika. Przedstawione zostały dane pomiarowe oraz ich analiza. EN The article presents an analysis of the dynamic characteristics of moving contact during closing fast high-voltage switch using techniques to improving the work of switch. The aim of this study was to determine the effects of significant design features of switch contact system on the process of non-simultaneous contacts junction and on value of scatter closing time of switch. The study used specialized measurement laboratory. Measurement data and their analysis were presented. |

Reference: make/making Reference information: 7. Make Switch: The making switch or making device, as the name indicates, is employed to ensure that the short-circuit currents are applied correctly at the desired moment. The equipment is characterised by close making time and high making capacity. However, the breaking capacity is negligible as the making device is not used for circuit interruption. At the moment of making, the backup CB and the test CB are already closed. As such on closure if there is even a slight contact rebound the contacts might get burnt or even welded together. In order to ensure, that the contact separation is minimum on closure, a high air pressure is maintained in the chamber. The closing speed is also so high that the contacts are fully closed before the short-circuit current attains its peak value. http://www.engineeringenotes.com/electrical-engineering/circ... |
