The invention relates to the technical field of production of high-voltage electric switchgears, and aims to provide a high-voltage switch air box for an outdoor compact intelligent transformer station, and solve the problems that in the prior art, switchgear components on a center pillar are large in type and distributed in a scattered manner, so that the integration level is low, the running and the maintenance are inconvenient. The high-voltage switch air box comprises a box body, operating mechanisms, high-voltage melting bins, high-voltage extending inner cones, a high-voltage lightning arrester sleeve, high-voltage outgoing line inner cones, a voltage reducing kit, hoisting kits, a high-voltage three-position switch and the like, wherein the high-voltage three-position switch is arranged at the inner upper part of the box body; the high-voltage melting bins are arranged in the middle of the box body; the openings of the high-voltage melting bins are on the left side of the box body; the A-phase, the B-phase and the C-phase of the openings of the high-voltage melting bins are arranged longitudinally. The high-voltage switch air box has the advantages that the structural design is integrated and combined; the air box is sealed; sulfur hexafluoride gas is insulated; the surface is shielded. Therefore, personnel safety and equipment running safety are guaranteed sufficiently.
Description
technical field [0001] The invention relates to the technical field of high-voltage electrical switchgear manufacturing, in particular to a high-voltage switch gas box used in an outdoor compact intelligent substation of a power distribution network. Background technique [0002] In my country's distribution network, there are still a large number of pole-mounted switchgears. Especially in the rural 10kV distribution network, the substation system composed of high-voltage switches on the column, high-voltage drop-out fuses on the column, high-voltage surge arresters, transformers on the column, and low-voltage distribution boxes is the main power supply mode of the distribution network. The equipment in this system is scattered on the high platform on the column, and the electrical equipment is exposed to the air, which makes it difficult to solve the problems of equipment corrosion, aging and vulnerability to external force damage. The live conductor is exposed in the air,...
