The invention aims to: aiming at the problems, the invention aims to provide the wall bushing for the integrated centrally installed switchgear, so that the wall bushing is more convenient to install, and the generation of vortex is reduced.
The technical scheme is as follows: the utility model provides a put cabinet in disjunctor formula and use wall bushing, includes sleeve pipe body, inserts, conducting strip, flange, be equipped with a plurality of integrated into one piece connection's single tube on the sleeve pipe body, single tube interval arrangement, the inserts install in the lumen of single tube, the conducting strip wears to establish the inserts and laminate rather than, the flange with the outer peripheral face of sleeve pipe body is connected.
Further, the insert is in a pad shape, and the outer peripheral surface of the insert is inclined.
Further, an inclined step is circumferentially arranged in the lumen of the single tube, and the inclination of the step is matched with the inclination of the peripheral surface of the insert.
The outer periphery of the insert is inclined, and matched steps are arranged in the official cavity of each single tube, so that the insert is more convenient to install in the official cavity of each single tube.
Further, the through holes penetrating through the conductive bars are formed in the middle of the insert, and the through holes are rectangular, circular and oval in shape.
According to the type of the conducting bar, an insert with a proper through hole is selected and installed in the cavity of the single tube, the structure of the sleeve body is not required to be changed, and the interchangeability is improved.
Further, a plurality of fixing holes are formed in the flange at intervals, and the fixing holes encircle the periphery of the sleeve body.
The bolts are inserted into the fixing holes, and the wall penetrating pipe sleeve is installed on the centrally installed switchgear through the fasteners.
Furthermore, a plurality of single tubes are arranged at intervals to form L shapes, straight shapes and Z shapes.
Most preferably, the lumen of the single tube is oval.
Optimally, the sleeve body is formed by integrally casting epoxy resin.
Most preferably, the material of the insert is a silica gel pad.
The beneficial effects are that: compared with the prior art, the invention has the advantages that: when the wall bushing is installed on the centrally installed switchgear, the detachable inserts are arranged, holes can be directly formed in the centrally installed switchgear, the bushing body is installed firstly, the size of the conductive bars is not required to be considered, and then the appropriate inserts are selected for installation according to the type of the conductive bars, so that the installation is convenient, and the interchangeability is strong; because the sleeve body is integrally formed, the single pipes are not provided with the centrally installed cabinet plates, when the power is on, vortex formed by high current caused by the conduction of the metal plates is avoided, and meanwhile adverse effects such as temperature rise and the like caused by the vortex are reduced; the integral structure makes the installation intensity higher.

Detailed Description
The present invention is further illustrated in the accompanying drawings and detailed description which are to be understood as being merely illustrative of the invention and not limiting of its scope, and various modifications of the invention, which are equivalent to those skilled in the art upon reading the invention, will fall within the scope of the invention as defined in the appended claims.
The utility model provides a wall bushing for disjunctor formula centrally installed switchgear, as shown in fig. 1 ~ 6, including sleeve pipe body 1, inserts 2, the conducting strip 3, flange 4, sleeve pipe body 1 is by epoxy integrative casting molding, sleeve pipe body 1 is equipped with a plurality of intervals and arranges, single tube 11 that the pipe wall is relative, single tube 11 arranges and is L type, in addition, can also arrange and be a style of calligraphy, Z type etc. inserts 2 are the cushion slice, the material is silica gel, inserts 2 are installed in the lumen of single tube 11, inserts 2's outer peripheral face sets up to the slope form, simultaneously, set up inclined step 111 along circumference in the lumen of single tube 11, step 111's inclination matches with inserts 2 outer peripheral face's inclination, make inserts 2 more simple and convenient when packing into single tube 11's lumen, single tube 11's lumen is oval. The middle part of inserts 2 has been seted up through-hole 21, and according to the difference of the model of conducting bar 3, the shape of through-hole 21 can be rectangle, circular, oval etc. and the size of through-hole 21 matches with the size of conducting bar 3, and conducting bar 3 inserts in through-hole 21 and laminating with inserts 2. The flange 4 surrounds the sleeve body 1 and is connected with the outer peripheral surface of the sleeve body 1, a plurality of fixing holes 41 are formed in the flange 4 along the axial direction of the wall bushing at intervals, the fixing holes 41 surround the outer periphery of the sleeve body 1, the fixing holes 41 are used for installing the wall bushing on the centrally installed switchgear, bolts are inserted into the fixing holes 41, and the wall bushing is installed on the centrally installed switchgear through bolt connection.
When the combined installation of the through-wall pipe sleeve is carried out, firstly, only holes matched with the size of the sleeve body are required to be formed in the centrally installed switchgear, and as the sizes of the sleeve bodies 1 are the same, the holes are quite convenient to form in the centrally installed switchgear without considering the structural sizes of the conductive bars, and in addition, as one through-wall pipe sleeve can be provided with a plurality of conductive bars, the arrangement of the sleeve bodies is more convenient and quicker; according to the model size of the conducting bar, an insert with a proper through hole is selected and is filled into a tube cavity of a required single tube, and then the conducting bar is inserted into the through hole of the insert, so that the whole process is very simple, and the installation time is saved; in the later stage, if the conducting bar is required to be replaced, only the existing conducting bar and the inserts are required to be disassembled, the proper inserts are selected again for reinstallation, the through-wall pipe sleeve is not required to be installed on the centrally installed switchgear in a re-perforating mode, the interchangeability is high, and the cost is greatly saved; because the sleeve body is of an integrally formed structure and is made of epoxy resin, metal parts such as a centrally installed switchgear plate and the like do not exist between the single pipes, and therefore, when the conducting bars are electrified, vortex formed by high current caused by the metal parts is greatly reduced, and adverse effects such as temperature rise and the like caused by the vortex are reduced.
