Abstract

The utility model relates to a looped network cabinet comprising a connecting column and two cloth storage assemblies which are arranged at the two ends of the connecting column and symmetrical about the connecting column. The two ends of the connecting column are respectively provided with external threads. The two cloth storage assemblies are respectively connected with the threads of the two ends of the connecting column. Each cloth storage assembly comprises a positioning plate, multiple reinforcing ribs and a cylindrical threaded buckle. The reinforcing ribs are evenly arranged on the positioning plate. One end, which is away from the positioning plate, of the reinforcing ribs is provided with the threaded buckle. The bottom part of the threaded buckle is provided with a small hole. The internal wall of the threaded buckle is provided with internal threads. The internal threads of the threaded buckle are matched with the external threads of the two ends of the connecting column. The top part of one end, which is away from the positioning plate, of the reinforcing ribs is provided with a platform. The threaded buckle is clamped with the reinforcing ribs. Disassembling and replacement of components are facilitated and maintenance cost is reduced by the looped network cabinet via flexible connection. The copper connecting column and the threaded buckle are adopted and the fixing plate is additionally arranged so that stability and corrosion resistance of the overall device structure are enhanced and the service life is prolonged.

Description

Ring main unit

Technical field

The utility model relates to a kind of ring main unit.

Background technology

Along with the development of national economy, the progress of science and technology, the electricity consumption places such as industrial and mining enterprises, residential quarters, harbour and skyscraper have all started to use ring main unit on a large scale, ring main unit simple in structure, safe and reliable to operation, frequency of maintenance is low and operating cost is few, and advantage is very outstanding compared with traditional switch cubicle.

General ring main unit is all provided with inlet wire cable and occurs cable, and at present, because internal structure design is reasonable not, as shown in Figure 1, cable 5 passes from ring main unit body bottom, due to the bending radius of cable 5, thus need to below ring main unit body, set up the seat 6 that raises, in order to cable 5 cablings, so just make ring main unit overall volume increase, take up room, but also increased the length of cable 5 and the making material of shell, increased production cost.

Utility model content

The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, provide a kind of reasonable in design, the ring main unit that floor space is little and production cost is low.

The utility model solves the technical scheme that its technical problem adopts: a kind of ring main unit, comprise cabinet and be arranged on mechanism chamber, gas tank, insulator and the cable in cabinet, described gas tank is located at cabinet top, mechanism chamber is arranged on gas tank one side, insulator is arranged on the side that gas tank is relative with mechanism chamber, on described insulator, be connected with cable, described cable is protruding by cabinet inside by being opened in the aperture at cabinet top, and described insulator, cable and aperture are all at gas tank homonymy.

In order to protect cable, prevent cable and produce friction and make cable fracture with aperture edge because of distortion, in described aperture, be provided with rubber ring.

The beneficial effects of the utility model are: this ring main unit, by optimizing internal structure, changes cable path, makes cable without the outlet of detouring again, have shortened the length of inside cable and have reduced the seat that raises, and have saved production cost.

Brief description of the drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the structural representation of prior art ring main unit;

Fig. 2 is the structural representation of the utility model ring main unit;

In figure: 1. cabinet, 2. gas tank, 3. mechanism chamber, 4. insulator, 5. cable, seat 6. raises.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As shown in Figure 1, a kind of ring main unit, comprise cabinet 1 and be arranged on mechanism chamber 3, gas tank 2, insulator 4 and the cable 5 in cabinet 1, described gas tank 3 is located at cabinet 1 top, mechanism chamber 3 is arranged on gas tank 2 one sides, and insulator 4 is arranged on the side that gas tank 2 is relative with mechanism chamber 3, on described insulator 4, is connected with cable 5, described cable 5 is inner protruding by cabinet 1 by the aperture that is opened in cabinet 1 top, and described insulator 4, cable 5 and aperture are all at gas tank 2 homonymies.

In order to protect cable 5, prevent cable 5 and produce friction and cable 5 is ruptured with aperture edge because of distortion, in described aperture, be provided with rubber ring.

Compared with prior art, this ring main unit, by optimizing internal structure, changes cable 5 paths, makes cable 5 without the outlet of detouring again, has shortened the length of internal electrical cable 5 and has reduced the seat that raises, and has saved production cost.

Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.

Claims (2)

1. a ring main unit, it is characterized in that, comprise cabinet (1) and be arranged on the mechanism chamber (3) in cabinet (1), gas tank (2), insulator (4) and cable (5), described gas tank (2) is located at cabinet (1) top, mechanism chamber (3) is arranged on gas tank (2) one sides, insulator (4) is arranged on the side that gas tank (2) is relative with mechanism chamber (3), on described insulator (4), be connected with cable (5), described cable (5) is inner protruding by cabinet (1) by the aperture that is opened in cabinet (1) top, described insulator (4), cable (5) and aperture are all at gas tank (2) homonymy.
