VACUUM VOLTAGE BREAKER OVER RANGE FROM MIDDLE TO HIGH

摘要

A vacuum voltage breaker over the range from middle to high comprises a body (1) at least one pole member for location one vacuum insertion (2) wherein a pair of corresponding electric contacts are installed (3, 4), where a stationary electric contact (3) is electrically united with upper end (5) of the polar member body (1), an axial electrical contact (4) is electrically connected to a low end (6) of the body (1) of the polar member and is moved by an insulation pusher (7); herein, the insulation pusher (7) passes through a screen plate (8) installed on low body hole (1) of the polar member. A screen plate (8) is made of solid flexible insulation material, at least one sealing ring (9; 9a,9b) made of flexible material is formed on HYPERLINK "http://www.multitran.ru/c/m.exe?t=1166_1_2&s1=%EF%E5%F0%E8%F4%E5%F0%E8%FF" periphery of the screen plate (8).
