Abstract
The utility model relates to a switch cabinet, in particular to a combined type integral structure of a ring main unit. The combined type integral structure of a ring main unit is structurally characterized by comprising frame upright columns with modularization holes, frame crossbeams, mounting crossbeams, frame corner connecting parts, a compartment partition board and a panel. The frame upright columns are connected via the frame corner connecting parts to form an integral ring main unit frame, the frame crossbeams and the mounting crossbeams are fixed in the frame upright columns, the panel is fixed out of the frame upright columns, and the compartment partition board which is in close fit with a load switch in the ring main unit separates a cable chamber from a bus chamber. The combined type integral structure of the ring main unit has the advantages that the frame upright columns with modularization holes, the frame crossbeams, the mounting crossbeams, the frame corner connecting parts and the compartment partition boards are organically connected to form the combined ring main unit, and the combined ring main unit is easy to realize production, attractive in appearance, better in manufacturability and high in cost performance.
Description
Technical field
The utility model relates to switch cubicle, refers more particularly to a kind of composite type looped network cabinet overall structure.
Background technology
Along with the development of urban distribution network, more and more higher to the requirement of power stability and reliability, for the influence that system overhaul and fault are caused reduces as far as possible, China's urban distribution network generally adopts the ring network power supply mode now, and is therefore more and more to the demand of ring main unit.In China's distribution system, generally the ring main unit version of Cai Yonging is welded type or whole plank frame form.
The welded structure form is by angle steel or bent plate, and by the cabinet body structure form that the welding means realize, the outward appearance of this kind structure is obviously relatively poor, and the skeleton after the welding takes up space greatlyyer, can't realize pre-operation; Whole plank frame form is by the bending of whole plate, and realizes the making of side plate, top board, base plate, connects into cabinet by forms such as bolts then, and this kind cabinet type major part will be used two-fold limit structure, and higher to technology, equipment requirements, cost is also higher.
Summary of the invention
The purpose of this utility model is to overcome the problem that existing ring main unit exists, and the relatively poor and pre-operation difficulty of outward appearance of having avoided the welded type cabinet body structure is bigger, and whole plank frame is higher to technology, equipment requirements, the shortcoming that cost is also higher; Provide a kind of easy realization operation in advance, appearance looks elegant, manufacturability better and the high composite type looped network cabinet overall structure of cost performance.
The technical scheme that the utility model adopted is a kind of composite type looped network cabinet overall structure, its structural feature is: comprise the upright of frame, cruciform bracing, installation crossbeam, framework corner connector, compartment space bar and the panel that have the modularization hole, each upright of frame is connected to form whole looped network cabinet frame work by the framework corner connector, cruciform bracing, installation crossbeam are fixed in the upright of frame, panel is fixed in outside the upright of frame, has compartment space bar and on-load switch to closely cooperate in ring main unit cable vault and two spaces of bus-bar room are separated.
Utilize on-load switch to add close-fitting with it compartment space bar from body insulation structure, realize effective separation of cable vault and two compartments of bus-bar room, several digital and analog holes are arranged on upright of frame, crossbeam is installed to be connected with upright of frame with digital and analog hole on the upright of frame by tapping screw, realize flexible independent assortment, amount body location, upright of frame and cruciform bracing connect by framework corner connector and bolt.Change the mode that upright of frame and cruciform bracing in the past are fixedly connected by welding, easy accessibility.
The utility model can also be able to better realization in the following way:
On the cabinet door of cable vault, have cable vault's observation window, face the following ground connection cutter fracture of on-load switch, can realize the observation of ground connection cutter fracture down.
On the relay plate, have relay plate observation window, and have control room's observation window on the cabinet outside corresponding control room, relay plate observation window and the alignment of control room's observation window are offered, and see through two observation windows simultaneously, realize the observation to the isolation knife fracture of back, relay chamber.
The advantage of the utility model patent is, utilization has the upright of frame in modularization hole, cruciform bracing, crossbeam is installed, and framework corner connector and compartment space bar, organic connection by these versions forms a kind of composite type looped network cabinet, easily realize pre-the operation, appearance looks elegant, manufacturability is better, and cost performance height, take into full account the on-load switch version of present routine simultaneously, that utilizes on-load switch adds close-fitting with it compartment space bar from body insulation structure, closely cooperates by compartment space bar and on-load switch in ring main unit and realizes that cable vault and two spaces of bus-bar room effectively separate.

Embodiment:
Below in conjunction with accompanying drawing the utility model is described in further detail, can makes the professional and technical personnel more understand the utility model, following embodiment is made amendment, it all is possible adding and replacing, and does not all exceed protection range of the present utility model.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of composite type looped network cabinet overall structure, comprise the upright of frame 1, cruciform bracing 2, installation crossbeam 4, framework corner connector 3, compartment space bar 5 and the panel that have the modularization hole, each upright of frame 1 is connected to form whole looped network cabinet frame work by framework corner connector 3, cruciform bracing 2, installation crossbeam 4 are fixed in the upright of frame 1, panel is fixed in outside the upright of frame 1, has compartment space bar 5 and on-load switch 9 to closely cooperate in ring main unit cable vault 10 and 11 two spaces of bus-bar room are separated.On upright of frame 1, be processed with several digital and analog holes 15, installation crossbeam 4 can be fixed in the digital and analog hole 15 that adapts on the upright of frame by tapping screw as required, realize flexible independent assortment, amount body location.Upright of frame 1 need not welding with cruciform bracing 2, and the framework corner connector 3 by rectangular shape is connected with bolt.
