Abstract
The utility model discloses a novel isolation handcart comprising a handcart frame, insulators fixed on the upper part of the handcart frame, a lightening arrester fixed on the middle part of the handcart frame, and a counter, a roll feed mechanism and a valve unlatching mechanism which are fixed on the lower part of the handcart frame. There are two insulators, of which one is arranged on the upper side and the other is arranged on the lower side. Front ends of the insulators are respectively fixed with contact arms with plum-blossom-shaped contacts. A fuse is arranged between the two contact arms so that a conductive loop is formed. The upper end of the lightening arrester is connected with the upper end port of the fuse via conductive wires, and the lower end of the lightening arrester is connected with the counter via grounding wires and then is connected with ground. The novel isolation handcart has characteristics of being low in costs, simple in overall structure, high in structure intensity and easy to promote, etc.
Description
Technical field
The utility model relates to a kind of isolation handcart.
Background technology
The isolation handcart plays an important role in electric power system, but existing isolation handcart space is little, considers the requirement of insulation distance, can't realize that fuse, lightning arrester and counter all are installed on the requirement on the isolation handcart.
Summary of the invention
the problems referred to above that exist for solving existing runner wagon, the utility model provides a kind of novel isolation handcart, its technical scheme of taking is: comprise vehicle frame, be fixed on the insulator on vehicle frame top, be fixed on the lightning arrester at vehicle frame middle part, and the counter that is separately fixed at the vehicle frame bottom, shake into mechanism and valve opener, insulator is two that arrange up and down, their front end is fixed with respectively the contact arm that respectively carries Mume flower contact, consist of the galvanic circle by fuse between two contact arms, the upper end of lightning arrester connects the upper port of fuse by wire, its lower end is by ground connection after the earth connection linkage counter.
The utility model is optimized improvement in original mechanism, the handcart overall space has been strengthened many, therefore fuse, lightning arrester, counter unification can be installed on existing handcart.And this kind structure controlled range is large, and up and down contact die opening can require free adjustment between 350mm ~ 400mm with cabinet.
Therefore the utlity model has overall structure simple, structural strength is high, is easy to the characteristics such as popularization.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figure 1, insulator 3 is fixed on vehicle frame 9 tops, and insulator 3 is two that arrange up and down, and their front end consists of the galvanic circle by fuse 4 between fixing 1, two contact arm 1 of contact arm that respectively carries Mume flower contact 2 respectively.Lightning arrester 5 is fixed on vehicle frame 9 middle parts, counter 6, shake into mechanism 7 and valve opener 8 and be separately fixed at vehicle frame 9 bottoms, the upper end of lightning arrester 5 connects the upper port of fuse 4 by wire, its lower end should the isolation handcart fall vehicle frame 9 integral body by the rear ground connection of earth connection linkage counter 6, shake the 7 whereabouts 200mm into mechanism, adopt the less electric elements of overall dimension, guaranteed insulation distance, the isolation handcart that can satisfy present customer requirements is joined the scheme of fuse+lightning arrester+counter.
