Technical Field
[0001] The utility model relates to a transverse ring network cabinet gas box in the technical field of ring network cabinets. Background Art
[0002] In the prior art, the ring main unit gas box is generally equipped with an isolating switch and a circuit breaker, and the isolating switch is connected to the circuit breaker, wherein the isolating switch is arranged directly above the circuit breaker, so that the gas box as a whole appears to be relatively high. In special occasions, such as a box-type substation, the vertical height space is limited but the horizontal space is relatively sufficient. The ring main unit is placed therein, and the gas box is basically close to the top, which is not conducive to control and safety. Utility Model Content
[0003] The utility model aims to provide a ring main unit gas box with a switch horizontally combined, the overall height of which is effectively reduced, so that it is more suitable for occasions with limited vertical space height.
[0004] To achieve the above-mentioned purpose, the utility model provides a ring main unit gas box with a horizontal combination of switches, including a box body, in which a disconnect switch and a circuit breaker are horizontally arranged side by side, the disconnect switch and the circuit breaker are connected by a copper bus, an input connection terminal is arranged at the lower part of the box body, and the circuit breaker is connected to the input connection terminal, and an output connection terminal is arranged at the upper part of one side of the box body, and the disconnect switch is connected to the output connection terminal.
[0005] Compared with the prior art, the beneficial effect of the present invention is that by placing the two switches side by side horizontally, the vertical height of the box is reduced, so that the overall height of the ring network cabinet is effectively reduced. When placed in special occasions with limited vertical space, its top maintains a relatively ample distance from the top of the occasion, which is convenient for operation and ensures safety.
[0006] As a further improvement of the utility model, the disconnect switch and the circuit breaker are arranged on the upper part of the box, the working surface of the disconnect switch faces one side of the box and is parallel to the side plate of the box, the working surface of the circuit breaker faces the other side of the box, and the circuit breaker as a whole is parallel to the circuit breaker.
[0007] In this way, the box is divided into upper and lower parts, the switch is installed in the upper part, and the line input terminal is installed in the lower part. The two switches are placed longitudinally in the upper part of the box, and the space layout is more reasonable. It can not only effectively reduce the height of the air box, but also ensure that the overall horizontal width of the air box will not be too large, avoiding occupying too much horizontal space.
[0008] As a further improvement of the utility model, a rear cross beam is provided at the rear of the box body, and the two ends of the rear cross beam are respectively connected to the middle parts of the rear ends of the two side plates of the box body, the rear ends of the disconnect switch and the circuit breaker are fixedly connected to the rear cross beam, and screws are welded on the front plate of the box body, and the front ends of the disconnect switch and the circuit breaker are connected to the screws.
[0009] In this way, the front and rear ends of the circuit breaker and the disconnect switch can be effectively fixed in the gas box, ensuring that the overall installation is firm.
[0010] As a further improvement of the present invention, the disconnect switch is a load switch or an isolating switch; in this way, in situations where an obvious disconnection point is required to ensure safe maintenance, or where there are strict isolation requirements for the circuit, an isolating switch with a circuit breaker can be installed; and in situations where the load is relatively stable and the breaking capacity requirements are not too high or in some medium-voltage distribution systems, a load switch with a circuit breaker is used to distribute electrical energy and protect the line.

[0013] Among them, 1 screw, 2 circuit breaker, 3 front plate, 4 output connection terminal, 5 side plate, 6 disconnect switch, 7 rear beam, 8 copper busbar, 9 input connection terminal. DETAILED DESCRIPTION
[0014] The utility model is further described below in conjunction with the accompanying drawings:
[0015] like Figure 1-2 The ring main unit gas box with a horizontal combination of switches shown in the figure comprises a box body, in which a disconnect switch 6 and a circuit breaker 2 are arranged horizontally side by side, the disconnect switch 6 and the circuit breaker 2 are connected through a copper bus 8, an input connection terminal is arranged at the lower part of the box body, and the circuit breaker 2 is connected to the input connection terminal, and an output connection terminal 4 is arranged at the upper part of one side of the box body, and the disconnect switch 6 is connected to the output connection terminal 4.
[0016] The disconnect switch 6 and the circuit breaker 2 are arranged on the upper part of the box. The working surface of the disconnect switch 6 faces one side of the box and is parallel to the box side plate 5. The working surface of the circuit breaker 2 faces the other side of the box. The circuit breaker 2 is parallel to each other as a whole.
[0017] A rear crossbeam 7 is provided at the rear of the box, and the two ends of the rear crossbeam 7 are respectively connected to the middle of the rear ends of the two side plates 5 of the box, and the rear ends of the disconnect switch 6 and the circuit breaker 2 are fixedly connected to the rear crossbeam 7. A screw 1 is welded on the front plate 3 of the box, and the front ends of the disconnect switch 6 and the circuit breaker 2 are connected to the screw 1. The disconnect switch 6 is a load switch or an isolating switch.
[0018] In the utility model, a circuit breaker 2 and a disconnect switch 6 are placed on the upper part of the gas box, and the circuit breaker 2 and the disconnect switch 6 are both placed longitudinally and arranged side by side horizontally, that is, the wide sides of the circuit breaker 2 and the disconnect switch 6 are parallel to the side plates 5 of the gas box, and the narrow sides of the circuit breaker 2 and the disconnect switch 6 are the front and rear ends. The front end of the circuit breaker 2 is fixedly connected to the front plate 3 of the gas box by bolts, the rear end of the circuit breaker 2 is fixedly connected to the rear cross beam 7 arranged at the rear of the gas box, the front end of the disconnect switch 6 is fixedly connected to the front plate 3 of the gas box by bolts, the rear end of the disconnect switch 6 is fixedly connected to the rear cross beam 7 arranged at the rear of the gas box, and the disconnect switch 6 and the circuit breaker 2 are connected by a copper bus 8.
