Abstract
The utility model discloses a low-voltage switchgear. A switchgear body is composed of a top plate, a pedestal, a panel, a rear door plate and a rear chamber side plate which are all fixed to a frame and are mounted on the top, the bottom, the front, the back and the side surface of the frame, respectively. The panel is fixed in the front portion of the frame via a door hinged mounted on the frame. The frame is connected by three-way pieces from different directions. The inner part of the frame is divided into three spaced chambers: a unit assembly chamber, a bus chamber and a cable inlet and outlet chamber. The unit assembly chamber, the bus chamber and the cable inlet and outlet chamber are successively arranged from the back of the frame to the front of the frame. The unit assembly chamber is dispose in front of the bus chamber and free combination can be provided so that the low-voltage switchgear is highly applicable and can change flexibly. The compact arrangement enables space and cost to be saved, thus meeting needs of various projects. Meanwhile, through adoption of the three-way pieces, symmetry of installation is guaranteed, and the switchgear body is effectively prevented from heating due to eddy current generated by heavy current.
Description
Technical field
The utility model relates to a kind of low-tension switch cabinet.
Background technology
Low-tension switch cabinet is all generally for industries such as power plant, oil, chemical industry, gold metallurgy, skyscrapers, as transmission of electricity, distribution and electric energy conversion, use, and in actual use, usually many low tension switches are coupled together by main bus bar, realize the demand for control to distinct device.And, because main bus bar is in operation, often have huge electric energy to pass through, thereby cross section is also wider, is commonly called as electricity row, it is generally to consist of the copper bar of more difficult bending or aluminium row, can take more space.If the structural design of arranging is unreasonable, for the safety of switch cubicle, the accommodation that cost reaches a project, all can have a huge impact, cabinet also can produce very large heat because of the excessive generation eddy current of electric current simultaneously, and switch cubicle is produced to very large hidden danger.
The utility model content
In order to address the above problem, the utility model provides a kind of low-tension switch cabinet, solved the problem of heating heat radiation of the switch cubicle of prior art, and the design in the reasonable arrangement switch cubicle makes whole switch cabinet structure compactness, but the unit block independent assortment be applicable to multiple project demand.
The utility model specifically is achieved through the following technical solutions:
A kind of low-tension switch cabinet, cabinet is comprised of the other plate in top board, base, panel, Rear Door and rear storehouse be fixed on framework, top, bottom, front, back and side that they are arranged on respectively framework form, described panel is fixed on described framework front by the hinge be arranged on framework, between the framework of different directions, by three-way piece, be formed by connecting, described framework inside is respectively unit block chamber, bus-bar room and the turnover cable vault at three intervals, and described unit block chamber, bus-bar room and turnover cable vault are arranged in order to back-end framework by frame front end.
Be provided with interlock between the circuit breaker of described unit block chamber and door;
Described bus-bar room is installed main bus bar and distribution bus, and described main bus bar level is installed, and distribution bus is vertically installed;
Be provided with burst disk between described bus-bar room and turnover cable vault;
Described burst disk is provided with louvre;
The other plate in the top board of described framework, base, Rear Door and rear storehouse all is provided with louvre.
The useful effect that the utility model produces is: the utility model is arranged on the bus-bar room front end by the unit block chamber, can independent assortment, highly versatile, variation flexibly, and arrange the compact cost of having saved space-saving, can meet various project needs, adopt three-way piece to connect simultaneously and both guaranteed the symmetry of installing, also can effectively place the fever phenomenon that cabinet causes by producing eddy current because of large electric current.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
