Abstract
The invention discloses a modularized bus bar chamber for a switch cabinet. The modularized bus bar chamber for the switch cabinet comprises an independent shell of a box structure. Wall bushings are fixed to the shell, wherein each wall bushing is arranged through a corresponding hole formed in the side wall of the shell in a penetrating mode and is used for corresponding to one main bus bar. Each main bus bar coaxially and correspondingly penetrates through an inner hole of the corresponding wall bushing to enter the shell. Isolation fixed contacts are fixed to the bottom wall of the shell, wherein each isolation fixed contact corresponds to one main bus bar and comprises a bus bar connection conductor and a contact conductor, and each contact conductor is used for being matched with a corresponding isolation movable contact arranged outside the bas bar chamber in an on-off mode. Due to the fact that the modularized bus bar chamber for the switch cabinet is provided with the independent shell, the bus bar chamber can be installed to be an integrated module and then is in butt joint with the rest of the switch cabinet, and the bus bar chamber can be directly installed on a workbench. In this way, the problem that an existing bus bar chamber for the switch cabinet needs to be installed in a high cabinet body is solved, installation is convenient, flow line production of the modularized bus bar chamber can be achieved, and the improvement in the production efficiency is facilitated.
Description
Technical field
The present invention relates to the bus-bar room for distribution switchgear cabinet.
Background technology
Metal enclosed switchgear (being called for short " switch cubicle ") has occupied middle pressure for the absolute market in panel switches field with its integrated high unique advantage.Switch cubicle on market is generally comprised of several compartments such as control room, bus-bar room, breaker chamber, cable vaults.During manufacture, all first to produce a whole cabinet shell, then adopt dividing plate to be divided into above-mentioned several independently compartment, bus-bar room is positioned at the top of cabinet, and general height is more than 2 meters, comparatively inconvenience when inner installation main bus bar and other part, when particularly switch cubicle rated current is larger, main bus bar is heavier, and what often adopt is that bolt connects, not only be difficult for installing, and installation personnel is also existed to certain potential safety hazard.The main bus bar of existing switch cubicle generally vertically adopts " one " word arrangement or " product " word arrangement from the top down in addition, then main bus bar adopts bolt to be connected with branch bar, branch bar is connected with external isolation fixed contact by contact box again, and main bus bar also needs supporting insulator to be fixed on cabinet simultaneously.This structure cause busbar branches more, fixing loaded down with trivial details, waste material and bus-bar room height increased.
Summary of the invention
After the object of the present invention is to provide a kind of can independently assembling, be installed to again the switch cubicle modularization bus-bar room on switch cubicle.
Technical scheme of the present invention is: a kind of switch cubicle modularization bus-bar room, comprise main bus bar, also comprise the independently shell of body structure, on shell, be fixed with by the respective aperture on side wall of outer shell, install for the wall bushing corresponding with each main bus bar, wall bushing has the endoporus with the coaxial setting of main bus bar, the coaxial correspondence of described main bus bar penetrates the endoporus of wall bushing and enters shell, on the diapire of shell, be fixed with the isolation fixed contact corresponding with each main bus bar, isolation fixed contact comprises that the bus connection conductor that is connected conducting with main bus bar of upper end cut-offs with the isolation moving contact for bus-bar room outside being connected with bus connection conductor the contact conductor coordinating, on the diapire of shell, offer the hole that supplies described contact conductor or adaptive isolation moving contact to pass.
The endoporus of described main bus bar and wall bushing extends along left and right horizontal direction, main bus bar have three-phase and in the horizontal direction before and after be arranged in juxtaposition.
The periphery of described wall bushing is provided with the sidewall of ring flange and shell and fixes with bolt.
Described bus connection conductor is platy structure, main bus bar is that two semicylinders are two D shape buses of two D shapes to the synthetic cross section perpendicular to axis, and the platy structure of bus connection conductor is clamped and use by two semicylinders of main bus bar the bolted radially installing.
Described contact conductor is established axis to the circular pipe type structure of the jack of downward-extension in being, bus connection conductor and the contact conductor of isolation fixed contact are upper and lower integral structure, on the top of contact conductor, in the place, both sides of bus connection conductor, leave the through hole that the jack inner with it communicates.
Described outer casing bottom side is processed with for adopting the fixing installing hole of bolt with switch cabinet remainder.
Described contact conductor outside is provided with the insulating case being cast for it on whole diapire that is fixed on bus-bar room, and one end of described main bus bar is supported on wall bushing, the other end is supported on insulating case by bus connecting piece and contact conductor.
Described insulating case passes bus-bar room downwards by the respective aperture on bus-bar room diapire, the inner corresponding isolation moving contact through hole that pass, that communicate with the jack of contact conductor leaving for switch cubicle of edge cover.
Switch cubicle of the present invention has independently shell with modularization bus-bar room, therefore after bus-bar room can being installed as to an integral module, dock with switch cubicle remainder again, therefore directly just energy installation on workbench of this bus-bar room, having solved existing switch cabinet bus need complete in higher cabinet, make to install more convenient, bus-bar room after modularization can be realized streamline production simultaneously, is beneficial to and enhances productivity.
Further, in bus-bar room of the present invention, three-phase main bus bar is along cabinet horizontal direction, and front and back level " " font is arranged, can be reduced bus-bar room height.
Further, main bus bar of the present invention is directly supported and fixed on the isolation fixed contact of bottom pouring insulating case, has save supporting insulator and branch bar, has saved cost, makes fixed form simplify simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of modularization bus-bar room of the present invention;
Fig. 2 is the schematic perspective view of the embodiment of modularization bus-bar room of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, the embodiment of modularization bus-bar room of the present invention, this bus-bar room is a standalone module, the shell 1 that comprises body structure, shell 1 has roof, diapire and surrounding sidewall, and adaptive main bus bar 2 ecto-entads penetrate in shell 1, the sheet-metal type body structure that described shell 1 is sealing, by adopting after sheet metal bending, bolt is assembled to be made, and each face of shell can be dismantled separately, and inner components can be installed easily.Main bus bar 2 have three-phase and in the horizontal direction before and after be arranged in juxtaposition, each main bus bar 2 axis extend along left and right directions, on shell 1, be fixed with the wall bushing corresponding with each main bus bar 7 installing by the respective aperture on sidewall, wall bushing 7 has and the coaxial endoporus extending along left and right horizontal direction arranging of main bus bar 2, the periphery of wall bushing 7 is provided with the sidewall of ring flange and shell 1 and fixes with bolt, and the coaxial correspondence of main bus bar 2 penetrates wall bushing 7 endoporus and enters shell 1.On the diapire of shell 1, be fixed with the isolation fixed contact corresponding with each main bus bar, isolation fixed contact comprises that the bus connection conductor 3 that is connected conducting with main bus bar 2 of upper end is connected with bus connection conductor 3 and to the contact conductor 4 of downward-extension.
