The invention discloses a
solid-insulated closing
assembly for a high-
voltage alternating-current
vacuum switch cabinet, comprising a fixing-sealing spine made of an insulating material as well as an irregular conducting rod, a first conducting plate, a second conducting plate, a one-phase vacuum
circuit breaker and an end seat thereof, a vacuum isolation switch and an end seat thereof, a vacuum grounding switch and an end seat thereof, a
lightning arrester and an end seat thereof, a
voltage transformer end seat and an interbus end seat which are fixedly sealed in the fixing-sealing spine. The moving contact of the vacuum isolation switch and the first conducting plate as well as the moving contact of the vacuum
circuit breaker and the second conducting plate are movably connected via a middle
sliding contact respectively. The
solid-insulated closing
assembly has the following advantages that the traditional separate high-
voltage components are integrated in the fixing-sealing spine, and all the electrified parts are packaged by adopting the
solid insulating material and isolated from outside air, so that an
electric shock hazard is avoided, and the use is
safer. The overall size, weight,
consumables and equipment floor area are reduced, and the solid-insulated closing
assembly is convenient to connect and suitable for being used in all working conditions and high-altitude conditions.
