Abstract

The invention discloses a novel integrated combined electrical appliance. The novel integrated combined electrical appliance comprises a three-station disconnecting switch, a vacuum breaker or a load switch or a load switch-fuse combined electrical appliance which is matched with the three-station disconnecting switch, and an operating mechanism, wherein the three-station disconnecting switch is arranged on the upper side of the integrated combined electrical appliance and distributed in the sequence of front, middle and back; other electrical elements are embedded into epoxy embedded poles and arranged below the disconnecting switch; the epoxy embedded poles are spliced together to form a partition plate so as to separate a bus room from a switching cable room; in addition, the upper outgoing lines of the other electrical elements form the disconnecting link rotating pivots of the three-station disconnecting switch; the operating mechanism is a novel difunctional spring operating mechanism and is arranged at the front end of the integrated combined electrical appliance; a torsional spring energy storage mechanism at the upper end of the operating mechanism drives the rotating shafts of the three-station disconnecting switch to act so as to open and close; and a spring winding energy storage mechanism at the lower end of the operating mechanism drives the other electrical elements to operate. Current sensor installing rooms and line slots are reserved at the lower ends of the epoxy embedded poles, so that the novel integrated combined electrical appliance has a compact structure and is safe in use, room and fault sources are reduced, and cost is lowered.

Description

Technical field:

[0001] The present invention relates to an electric appliance, which is related to a combined electric appliance, especially a new combination of an innovative three-position isolating switch and an innovative vacuum circuit breaker (load switch, load switch-fuse combined electric appliance) related to electrical appliances. Background technique:

[0002] A group of switch cabinets is formed by the arrangement and combination of different design schemes, and the main electrical components used in different design schemes are also different. Usually, the incoming line cabinet and contact cabinet use isolating switch + circuit breaker + grounding switch; At present, there are two kinds of switch cabinets commonly used: one is a removable middle cabinet with A, B, C arranged left, middle, and right, and the other is a box-type fixed cabinet with A, B, and C rear, middle, and front arranged. . The appearance of the removable type is larger, and the appearance...
