Description

A kind of fixedly cellular-type functional unit of low-tension switch cabinet

Technical field

The utility model relates to a kind of fixedly cellular-type functional unit of low-tension switch cabinet, belongs to the electric connection technique field of low-tension switch cabinet.

Background technology

The functional unit of low-tension switch cabinet has fixedly cellular-type or two kinds of forms of pull-out type, fixedly the element of cellular-type functional unit is hard-wired, with cabinet for fixedlying connected, and the element of draw-out type functional units is installed in the drawer, move with drawer, and be that pull-out type is connected with cabinet, hence one can see that, and two kinds of functional units are different with the connected mode of cabinet, so structurally there is a great difference, so should not adopt simultaneously in same switch cubicle, saying nothing of is to load in mixture arbitrarily.

The inlet wire connected mode of the fixedly separation function unit of existing low-tension switch cabinet is fixedly connected, the inlet wire conductor is connected by bolt with vertical busbar, though this traditional connected mode is simple, also there is open defect in it: must process the hole that matches with the corresponding size in functional unit position on vertical busbar; When the functional unit electric current is big, can't adopt hard bus to connect; And for later on fixedly between the separation function unit or the transformation between two kinds of functional units, all must through fixedly connected loaded down with trivial details disassembly process and run into vertical busbar and the functional unit correspondence position on whether porose, problem that whether hole matches, and this problem directly has influence on the difficulty and the feasibility of transformation, mismatch as atresia or hole and then need on each vertical busbar, punch, cause the down whole vertical bus of necessary dismounting system like this, make improvement project great, complicated loaded down with trivial details, cost improves.

Equally, the fixedly cellular-type functional unit that transform low-tension switch cabinet for the draw-out type functional units with low-tension switch cabinet as also is complicated and infeasible in existing structure, wherein relate to and on each vertical busbar, to punch, cause the down whole vertical bus of dismounting system, the same gigantic project of this operation, complicated loaded down with trivial details, cost improves, and this has just directly limited freely selecting for use of user and has strengthened the difficulty that later switch cubicle is transformed.

So-called switch cubicle transformation; generally be meant because the conversion of protected plant capacity causes the protection capacity of controller switching equipment to need change, such as; the fixedly cellular-type functional unit of a larger capacity is transformed into the less draw-out type functional units of two or more capacity, perhaps opposite change etc.

In addition, because the space is narrow and small in the cabinet, adopt fixedly its element installation of cellular-type functional unit, circuit connection, plant maintenance etc. that certain difficulty is all arranged.

Summary of the invention

Draw-out type functional units mutual alternative during technical problem to be solved in the utility model provides a kind of energy and is installed in drawer, load in mixture, be beneficial to the transformation of switch cubicle and need not on the vertical busbar of low-tension switch cabinet punching and the fixedly cellular-type functional unit of the low-tension switch cabinet of installation and wiring cabinet outside integrally.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of fixedly cellular-type functional unit of low-tension switch cabinet, the inlet wire conductor 6, the outlet conductor 7 that comprise mounting panel 1, be fixed in the primary element 8 of mounting panel 1, be connected with described primary element 8 respectively, described inlet wire conductor 6 is connected by the outer vertical busbar plug of plug-in unit and fixing cellular-type functional unit.

Plug-in unit described in the utility model is an adaptor.

Adaptor described in the utility model is a major loop plug-in unit 2.

By adopting technique scheme, make the fixedly cellular-type functional unit of the low-tension switch cabinet that is provided be replaced to draw-out type functional units, avoided punching and loaded down with trivial details vertical busbar disassembly process on vertical busbar, install and change all simple and reliable, be particularly advantageous in the capacity transformation with switch cubicle of loading in mixture of functional unit.

Embodiment

The utility model is described in further detail by preferred embodiment below in conjunction with accompanying drawing.

Referring to Fig. 1,3, circuit breaker 8 is installed on the mounting panel 1 and connects inlet wire conductor 6 and outlet conductor 7 (this turnover line conductor can be cable or copper bar), current transformer 9 is installed on the outlet conductor 7, major loop plug-in unit 2 is installed on the dividing plate 4 and with inlet wire conductor 6 usefulness bolts and connects firmly, to enter in the switch cubicle from the front as a fixed part with top then, major loop plug-in unit 2 inserted terminals are pegged graft with vertical busbar 13 to put in place, then mounting panel 1 and supporting plate 12 are connected firmly, with dividing plate 4 and switch cubicle central post, vertical bus cover left plate 16 and vertical bus cover right plate 17 connect firmly, after secondary connection is finished, from the switch cubicle rear side with shrouding 5 and switch cubicle central post, vertical bus cover right plate 17 connects firmly and makes outlet conductor 7 to pass the bigger slotted eye of processing in advance on the shrouding 5, then be that major loop adaptor 3 is enclosed within on the outlet conductor 7 and with shrouding 5 and connects firmly, again outlet conductor 7 and major loop adaptor 3 are connected firmly, wherein major loop adaptor 3 plays a part herein is fixing outlet conductor 7, can replace this major loop adaptor 3 with other fixture.So just having finished whole fixedly cellular-type functional unit installs and wiring, certainly, under the prerequisite that does not influence secondary connection, shrouding 5 and major loop adaptor 3 also can be installed on the outlet conductor 7 in advance, and just enter in the switch cubicle from the front as a fixed part integral body and install with top, avoided in the small space of traditional fixedly cellular-type mounting structure, operating, can raise the efficiency.

Major loop adaptor 3 herein also can adopt major loop plug-in unit 2 to replace, and for convenience in the future in the switch cubicle transformation process and the mutual alternative of draw-out type functional units, connector has adopted the structure similar with the draw-out type functional units connector herein.
