Distribution station simplified electrical high - voltage has three channels, in particular the distribution station of a network of supplying high - voltage chart according to a so-called cut-off artery or loop

摘要

This three-path high-voltage electrical distribution substation comprises a breaker switch 9 which is connected between the first and second paths 3 and 4 so as to allow their direct coupling/decoupling, and an inverter 10 with central neutral point, which is connected to the three paths 3, 4 and 31 so as to allow the coupling of the third path 31 to any one of the first and second paths 3 and 4. Preferably, the breaker switch 9 and the inverter 10 are arranged in a single housing 7 made of an insulating material and filled with an insulating fluid and consisting of two shells assembled together in a leaktight manner, the breaker switch and the inverter each containing an operating spindle which passes in a leaktight manner through the wall of the housing 7.
