Abstract
The invention relates to a commutation block for a low-voltage circuit breaker. The commutation block comprises an insulation shell, an insulation plate, two curved connecting plates and a straight connecting plate; the insulation plate is arranged on the inner upper part of the insulation shell; the middle part of the straight connecting plate is arranged on the middle-lower part of the insulation shell in a penetrating manner along the front-rear direction; each curved connecting plate is a Z-shaped structure consisting of a vertical plate and two horizontal plates, the two horizontal plates are formed by horizontally extending the lower edge of one end and the upper edge of the other end of the vertical plate, the vertical plate of each curved connecting plate is arranged in a front-rear space of the inner upper part of the insulation shell, and the two horizontal plates respectively penetrate through the front end surface and the rear end surface of the insulation shell to extend to the exterior. Connecting conductive wires on the commutation block are not laminated, so that no abrasion is produced among the conductive wires in the installation process, and the short-circuit fault among the conductive wires can be avoided; moreover, the appearance structure is regular. In addition, the commutation block also has the advantages of simplicity and compactness in structure, small occupied space, low cost, convenience in installation and use and the like.
Description
Technical field
The invention belongs to low voltage electrical apparatus technology field, particularly relate to a kind of low-voltage circuit breaker commutation piece.
Background technology
Some particular places in distribution system application need to be changed power phase, mostly traditional mode is to adopt the mode that the connection wire of commutation piece on low-voltage circuit breaker is overlapped to realize, so not only can make the surface structure of product seem in disorder, and between wire, easily produce and wear and tear in installation process, thereby while causing using,, because long-term fever makes wire insulation hydraulic performance decline, result causes the fault of leading short-circuit between conductors.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of low-voltage circuit breaker commutation piece.
In order to achieve the above object, low-voltage circuit breaker provided by the invention is arranged on low-voltage circuit breaker end of incoming cables or leading-out terminal with commutation piece, and it comprises insulation crust, insulation board, two curved joint covers and a straight type joint cover; Wherein insulation crust is cuboid case structure; Insulation board is vertically set on the internal upper part of insulation crust, two spaces before and after thus the top of insulation crust being divided into; Straight type joint cover is horizontally disposed with, and the middle and lower part that is arranged on insulation crust is run through at middle part along fore-and-aft direction, and two ends are formed with respectively a wiring hole; Curved joint cover is by vertical panel and two zigzag structures that level board forms, two blocks of level boards horizontally outward extend and form from one end lower edge and the other end top edge of vertical panel respectively, and on each level board, be formed with respectively a wiring hole, two curved joint covers are symmetrical arranged, wherein the vertical panel on every curved joint cover is separately positioned in the space, front and back of insulation crust internal upper part, and two blocks of level boards run through respectively the front/rear end of insulation crust and extend to outside.
Described insulation board is laminated epoxy glass-cloth board.
Connection wire on low-voltage circuit breaker use commutation piece provided by the invention is non-overlapping each other, so between wire, can not produce wearing and tearing in installation process, thereby can avoid leading the fault of short-circuit between conductors, and surface structure is neat.In addition, this commutation piece also have simple in structure, compact, take up room little, cost is low, the advantage such as easy to install.

Embodiment
Below in conjunction with the drawings and specific embodiments, low-voltage circuit breaker provided by the invention is elaborated with commutation piece.
As Figure 1-Figure 5, low-voltage circuit breaker provided by the invention is arranged on low-voltage circuit breaker end of incoming cables or leading-out terminal with commutation piece, and it comprises insulation crust 1, insulation board 2, two curved joint covers 3 and straight type joint covers 4; Wherein insulation crust 1 is cuboid case structure; Insulation board 2 is vertically set on the internal upper part of insulation crust 1, two spaces before and after thus the top of insulation crust 1 being divided into; Straight type joint cover 4 is horizontally disposed with, and the middle and lower part that is arranged on insulation crust 1 is run through at middle part along fore-and-aft direction, and two ends are formed with respectively a wiring hole; Curved joint cover 3 is by vertical panel and two zigzag structures that level board forms, two blocks of level boards horizontally outward extend and form from one end lower edge and the other end top edge of vertical panel respectively, and on each level board, be formed with respectively a wiring hole, two curved joint covers 3 are symmetrical arranged, wherein the vertical panel on every curved joint cover 3 is separately positioned in the space, front and back of insulation crust 1 internal upper part, and two blocks of level boards run through respectively the front/rear end of insulation crust 1 and extend to outside.
Described insulation board 2 is laminated epoxy glass-cloth board; Insulation crust 1 adopts PBT material to make.
Now low-voltage circuit breaker provided by the invention is described below by commutation piece using method: end of incoming cables or the leading-out terminal that can use it for low-voltage circuit breaker all can, realize the function that need to change phase sequence, as shown in Figure 6, by input A, B, C mutually three wires is connected to the level board wiring hole that is positioned at three joint covers on insulation crust 1 front end face, simultaneously by output C, B, A mutually three wires is connected to the level board wiring hole that is positioned at three joint covers on insulation crust 1 rear end face, after the conversion of this commutation piece, the A of input, B, C will become the C of output, B, A phase.
