Abstract

The invention relates to a combined electrical appliance. The combined electrical appliance consists of a double-vacuum bubble immobilized pole high-voltage load switch unit, a fuse box, an operating mechanism and a novel cabinet body. Compared with the prior art, the combined electrical appliance has the following advantages that: 1, the epoxy resin immobilization and connection of the high-voltage load switch unit and the fuse box is realized; 2, the horizontal layout of the high-voltage load switch unit and a fuse under the condition of not changing the width of a high-voltage load switch is realized; 3, the tripping state of the fuse is very easy to observe intuitively and obviously through a cabinet door observation window, and the influences of troubles and reliable factors caused by performing secondary simulation are avoided; and 4, a tripping mode is that a tripping semiaxle in the operating mechanism is directly pushed by adopting a pull rod, the design is simple and the operation is reliable.

Description

Technical field [0001] The invention relates to a high-voltage load switch+fuse combined electric appliance and power distribution equipment in high-voltage switchgear, belonging to the field of high-voltage power transmission and distribution in power systems. Background technique [0002] In response to the "Tokyo Protocol" to reduce greenhouse gas emissions, replace SF with high-voltage load switches for vacuum interrupters 6 Insulated high-voltage load switches have become a common consensus; in the field of high-voltage switchgear transmission and distribution, high-voltage load switches and their switchgear are used for incoming and outgoing line units in the field of power transmission and distribution, and usually, transformer protection units choose high-voltage Load switch + fuse combination electrical unit. [0003] The combined high-voltage load switch and its high-voltage switchgear developed by our company applied for an invention patent in January 2008. In or...
