Abstract
The utility model discloses left and right side plate manholes of a switch cabinet enclosing bus bridge. The manholes are arranged on left and right side plates (3). In addition, left and right side sealing plates (4) which are provided with shutters (10) are fixed on the left and right side plates (3) through riveting nuts (6). During installation and overhauling, the left and right side sealing plates (4) are opened and then the installation and the overhauling can be performed. At present, when cabinet top and roof spaces are small, the used bridge can not be installed and overhauled. By using the manholes of the utility model, the above problem is solved. The installation and the overhauling are more convenient and rapid.
Description
Technical field
The utility model relates to the enclosed busbar crane span structure in the electrical power distribution system switchgear.
Background technology
Nowadays, power distribution cabinet has been widely used in the electric power occasions such as low-voltage-powered control centre and motor control center of industries such as the power plant of big single-machine capacity, extensive petrochemical industry.Adopt the contact of enclosed busbar crane span structure form between the contact cabinet, between cabinet and the transformer.Its installation and manhole are generally the upper sealing plate maintenance, and it is a design that its left side plate generally adopts monnolithic case.In practical application, this form runs into when distance is smaller between roof and the cabinet top to the user scene, receives spatial constraints, and the installation and maintenance personnel can't be from top installation and maintenance, and this has had a strong impact on installation and maintenance.Particularly there were many in recent years and carried out the switch cubicle transformation, and the user of motionless old switchgear house, so this has become pressed for the problem of consideration today especially.
The utility model content
The utility model is a switch cubicle enclosed busbar crane span structure left side plate manhole structure of designing a kind of and installation, convenient disassembly.
The technical scheme of the utility model is: a kind of switch cubicle enclosed busbar crane span structure left side plate manhole is characterised in that on left side plate, have manhole, other has the left and right sides shrouding that is equipped with shutter to be fixed on the left side plate with riveting nut.
The switch cubicle enclosed busbar crane span structure left side plate manhole that the utility model provides; Bus and other parts thereof directly are installed in the crane span structure from left side plate; Bus is installed and is not received extraneous spatial constraints; And installation, convenient disassembly have overcome the former upper sealing plate that is used in and have installed, overhauled the many drawbacks of space-constrained.
Description of drawings
Fig. 1 is the structural representation of the utility model switch cubicle enclosed busbar crane span structure left side plate manhole;
Fig. 2 is the structural representation of the utility model switch cubicle enclosed busbar crane span structure left side plate manhole shrouding.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure: 1, frid 2, upper sealing plate 3, left side plate 4, left and right sides shrouding 5, bus 6, riveting nut 7, base plate 8, bus pillar 9, bolt 10, shutter
Shown in accompanying drawing, the utility model switch cubicle enclosed busbar crane span structure left side plate manhole is on left side plate 3, to have manhole, and other has the left and right sides shrouding 4 usefulness riveting nuts 6 that are equipped with shutter 10 to be fixed on the left side plate 3.
The utility model switch cubicle enclosed busbar crane span structure left side plate manhole; Install, when overhauling open left and right sides shrouding 4; Just can install, overhaul, it is little with roof space that the formula left side plate of crane span structure that has solved present use effectively runs into the cabinet top, the problem that can't carry out installation and maintenance; The original history to carry out installation and maintenance from the upper sealing plate of gantry top only that is through with makes the installation and maintenance of later switch cubicle crane span structure convenient, quick.
