Abstract
The utility model discloses wire inlet and outlet terminals of a high-voltage alternating-current demarcation circuit breaker, which include an extension type three-phase wire inlet terminal and an extension type three-phase wire outlet terminal. The extension type three-phase wire inlet terminal and the extension type three-phase wire outlet terminal are respectively arranged on two sides of a case, and extending sections of the three-phase wire inlet terminal and the three-phase wire outlet terminal are respectively radially arranged from the two sides of the case outwards. The air insulation distance between the wire inlet terminal and the wire outlet terminal is greatly increased, and accordingly safety of the high-voltage alternating-current demarcation circuit breaker is improved.
Description
Technical field
The utility model relates to a kind of binding post, relates in particular to a kind of three-phase parallel type of high-voltage alternating demarcation circuit breaker that is applicable to into and out of line terminals.
Background technology
Be respectively arranged with the three-phase that stretches out in the casing both sides of high-voltage alternating demarcation circuit breaker into and out of line terminals, adopt the parallel mode of connection to be connected respectively into and out of line terminals with line cord, owing to be subjected to casing self size restrictions, into and out of comparatively compact between the line terminals, cause into and out of air insulation close together between line terminals, fail safe can not get guaranteeing.
Summary of the invention
Goal of the invention: the purpose of this utility model is to address the above problem, and provides a kind of three-phase parallel type that is applicable to the high-voltage alternating demarcation circuit breaker into and out of line terminals, can improve greatly into and out of the air insulation distance between the line terminals.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme: a kind of high-voltage alternating demarcation circuit breaker is into and out of line terminals, comprise reach three-phase input terminal and three-phase outlet terminal that the casing both sides are set respectively, the section of stretching out of described three-phase input terminal and three-phase outlet terminal outwards is radial setting from the casing both sides respectively.
Wherein, described three-phase input terminal is identical with the structure of three-phase outlet terminal, described three-phase input terminal or three-phase outlet terminal comprise conducting rod, front end at conducting rod is provided with the cable connecting rod, outside at conducting rod coats the installing ring oxysome, coats cast silicon rubber body in the outside of installing ring oxysome.
Wherein, described cable connecting rod is flat, is provided with installing hole on the cable connecting rod.
The utility model has the advantages that: adopt radial setting into and out of line terminals, the exposed part of adjacent two terminal sections of stretching out is apart from being improved greatly, thereby guaranteed to have improved the fail safe of high-voltage alternating demarcation circuit breaker into and out of the air insulation distance between the line terminals; The front end of conducting rod is provided with the cable connecting rod, and conducting rod is connected by the bolted mode with line cord, and is easier for installation, and wiring is more firm.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of single binding post of the present utility model.
Fig. 3 is the vertical view of Fig. 2.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in Figure 1, a kind of high-voltage alternating demarcation circuit breaker of the present utility model comprises reach three-phase input terminal 2 and the three-phase outlet terminal 3 that casing 1 both sides are set respectively into and out of line terminals, the section of stretching out of described three-phase input terminal 2 and three-phase outlet terminal 3 outwards is radial setting from the casing both sides respectively, arrangement can make the end-to-end distance of the section of stretching out of adjacent two terminals from being improved greatly like this, thereby guaranteed to have improved the fail safe of high-voltage alternating demarcation circuit breaker into and out of the air insulation distance between the line terminals.
Shown in Fig. 2 and 3, described three-phase input terminal 2 is identical with the structure of three-phase outlet terminal 3, described three-phase input terminal 2 or three-phase outlet terminal 3 comprise conducting rod 4, front end at conducting rod 4 is provided with the cable connecting rod 5 that is flat, be provided with two installing holes 8 at cable connecting rod 5 middle parts, coat one deck installing ring oxysome 6 in the outside of conducting rod 4, coat the undulatory cast silicon rubber of one deck body 7 in the outside of installing ring oxysome 6 again.During wiring, adopt the bolted mode that the cable connecting rod 5 and the end coupling of line cord are fixed, compare with original mode of connection that needs to adopt cable clip to clamp, easy for installation, and also wiring is more firm.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
