Embodiment Construction

[0025] The concrete technical scheme of the present invention will be further described below in conjunction with embodiment:

[0026] like Figure 1 ~ Figure 2 As shown, the embodiment given by the present invention is a three-phase linkage drop-type sectionalizer, which includes an insulator, a conductive part consisting of an upper and lower moving contact, an upper and lower static contact using a multi-piece brush structure, and a middle conductive rod. 1. The detection part and the trip reset mechanism, which are composed of the sensor on the upper part outside the conductive tube and the electronic controller installed in the conductive rod tube, are the same as the prior art except that the trip reset mechanism has been greatly improved. The labels in the figure are: 1. Insulator, 2. Crossarm, 3. Interlocking insulator, 4. Two connecting plates, 5. Conductive rod, 6. Tripping automatic reset mechanism, 7. Detachable linkage mechanism, 8 .Linked reset pull ring.

Abstract

The related drop-off sectionalizer for self reset of a column mechanism comprises: a lower connection frame capped on the lower end of a conductive bar, a separate-brake spring, a slide block, a close-brake spring, a reset bump bar, which the last four members cap on the tripping connection rod of the conductive bar; a separation latch with front end hooked the pin of the lower movable contact and back end blocked the slide block, and a reset baffle on the lower supporting frame, wherein the column slide slot on a rotary slot side wall blocks the convex column on the slide block, and the breaking joint of the lower connection frame connects the former contact. This invention reduces labor strength and improves work efficiency.

Description

technical field [0001] The invention relates to a drop-type sectionalizer, which can realize the automatic reset of the mechanism on the column after breaking off in case of a fault. The utility model is a supplement to the existing drop-type sectionalizer varieties, and belongs to the technical field of high-voltage power distribution devices. Background technique [0002] At present, in the outdoor AC high-voltage distribution lines, most of the protection methods at home and abroad adopt the cooperation of reclosers and sectionalizers or the cooperation of circuit breakers with reclosing functions and sectionalizers. Therefore, sectionalizers are used as the main Switches have been widely used. However, because the structure of the sectionalizer is relatively complicated and the price is very expensive, people have done a lot of work on simplifying the structure of the sectionalizer, such as the "drop-type sectionalizer" given by the Chinese utility model patent No. 9220...
