Three-path high-voltage switching module, in particular for the public distribution substation of a high-voltage supply network in accordance with a so-called multipoint-ring, looped or dual-tapped arrangement

摘要

Three-path high-voltage switching module comprising a leaktight enclosure 1, made of an insulating material which is filled with an insulating fluid, and which contains three breaker switches 4, 5 and 6. The enclosure 1 consists of two moulded shells 1a and 1b assembled together in a leaktight manner. A first 4 and a second 5 of the three breaker switches 4, 5 and 6 are arranged side by side in a first 1a of the two shells whilst the third breaker switch 6 is arranged in the second shell 1b. A conducting bar 10, common to the three breaker switches and a fixed contact part 8 or 26 of each of the three breaker switches 4, 5 and 6 are carried by a support plate 9 made of an insulating material which is mounted in the enclosure 1 in proximity to the junction between the two shells 1a and 1b. <IMAGE>
