In this embodiment, the circuit breaker includes a three-phase horizontal sub-tank 202, the main conductor is disposed in the sub-tank 202, the sub-tank 202 extends in a lateral direction (left-right direction of fig. 4), the three-phase sub-tank 202 is arranged at intervals in a longitudinal direction, and the sub-tank 202 is supported on a longitudinal steel beam 2012. As shown in fig. 5, the three-phase box-dividing housing 202 is a middle-phase box-dividing housing 2021 in the middle and side-phase box-dividing housings 2022 on both sides, respectively. In this embodiment, the transverse girder 2011 is a channel steel extending transversely, and openings of the two channel steels are arranged in opposite directions, so that possibility is provided for integral hoisting and transportation of the GIS, and the channel steel comprises an upper airfoil surface and a lower airfoil surface; while longitudinal steel beam 2012 is i-beam.
The GIS further comprises a breaker operating mechanism 203 and a control cabinet 204 which are fixed on the underframe 201, wherein the breaker operating mechanism 203 is positioned between one end of the sub-box shell 202 and the control cabinet 204, the GIS further comprises a cable 205, the cable 205 is a secondary control cable, and all the using parts are connected into the control cabinet 204 to realize centralized control. Here, the bottom surface of the case of the breaker operating mechanism 203 is disposed to sink in the lateral girder 2011, and the bottom surface is higher than the lower wing surface of the lateral girder 2011.
To guide the cables 205 everywhere into the control closet 204, the GIS further includes a transverse wiring member 207 and a vertical wire slot 206, the transverse wiring member 207 is configured such that, as shown in fig. 5, 6 and 8, the transverse wiring member 207 extends in the transverse direction, the transverse wiring member 207 is arranged in the longitudinal direction in two, and the arrangement position of the transverse wiring member 207 is located between two adjacent box-divided housings 202, that is, between the middle-phase box-divided housing 2021 and the side-phase box-divided housing 2022. As can be seen from fig. 5, the outer peripheral surfaces of the sub-tank housings 202 are circular, and a space is naturally formed between the tops of the adjacent two sub-tank housings 202, in which the lateral wiring members 207 are located. The transverse wiring member 207 has a wiring passage inside, through which the cable 205 can pass transversely, and the transverse wiring member 207 includes a mesh bridge 2071, the mesh bridge 2071 extending transversely, the mesh bridge 2071 having a frame-like structure, and the side surface of the mesh bridge 2071 being in conformity with the shape of the outer peripheral surface of the box-divided casing 202 so as to be capable of being fitted between the two box-divided casings 202. The transverse wiring member 207 further comprises a groove cover 2072 fastened on the top of the grid bridge 2071, wherein a limiting buckle is arranged on the inner edge of the groove cover 2072 to form a limit with the grid bridge 2071, so that the groove cover 2072 is prevented from loosening and falling off. The limiting buckle utilizes the material rigidity of the groove cover 2072, and is convenient to process. As can be seen in fig. 6, the slot cover 2072 has a plurality of sections, and two adjacent sections are connected by a buckle or a buckle, so as to facilitate installation and disassembly.
By providing the groove cover 2072, it is possible to cooperate with the outer peripheral surfaces of the adjacent two box-divided cases 202, thereby protecting the mesh bridge 2071 and the cable 205 inside the mesh bridge 2071. Since the transverse wiring members 207 are buried in the space between the adjacent two divided cases 202, they are not visible from the outside, improving the overall aesthetic appearance. As shown in fig. 4, the use portion of the cable 205 is often located above the box-like housing 202, and a penetration hole is formed in the slot cover 2072 so that the cable 205 passes through in order to pass down into the transverse wiring member 207.
The GIS further includes a vertical wire slot 206, where the vertical wire slot 206 is located at one end of the box-dividing housing 202, the vertical wire slot 206 is in communication with the transverse wiring member 207 and is used for guiding the cable 205 downward, and the vertical wire slot 206 may be configured as a conventional wire slot, as shown in fig. 8, where an opening 2061 is provided at one end of the vertical wire slot 206, the opening 2061 is opposite to one end of the transverse wiring member 207, and the cable 205 penetrates into the vertical wire slot 206 after passing out of the transverse wiring member 207 and is guided downward. In this embodiment, the number of vertical slots 206 is equal to the number of lateral wiring members 207, and two vertical slots are provided. A top plate 208 is fixed on the top of the vertical wire slot 206, and a through hole is formed in the top plate 208 for the cable 205 to penetrate.
As shown in fig. 7 and 8, a cover plate 209 is fixedly installed at the top of the two longitudinal girders 2012, the cover plate 209 extends to the circuit breaker operating mechanism 203, and a bottom plate 210 is fixed on the lower wing surface of the longitudinal girders 2012, and the bottom plate 210 can extend to the bottom of the circuit breaker operating mechanism 203 because the bottom surface of the circuit breaker operating mechanism 203 is higher than the lower wing surface of the longitudinal girders 2012. With the cover plate 209, the bottom plate 210, the longitudinal steel beams 2012, the case of the circuit breaker operating mechanism 203, and the two longitudinal steel beams 2012, a closed space is formed as an inner cable passage. Because the box of the breaker operating mechanism 203 is blocked, the cable cannot directly extend to the junction box 204, as shown in fig. 7, a bottom wire slot 212 is fixed outside the two longitudinal steel beams 2012, and the bottom wire slot 212 and the longitudinal steel beams 2012 form a closed outer cable channel, and the outer cable channel extends to the junction box 204. To connect the inner cable channels inside with the outer cable channels outside, a transverse steel beam 2011 is open for the cables to pass through. The vertical wire slot 206 is fixed on the apron 209, and apron 209 upper opening power cable 205 penetrates in the chassis 201 downwards, and after the cable penetrated the cubicle 204, the cable 205 was assembled the back and is blocked with fire prevention mud, ensures that the cubicle 204 has waterproof performance.
In the invention, the cables 205 above the transverse wiring member 207 all enter the transverse wiring member 207 and enter the control cabinet 204 through the vertical wire slots 206 and the underframe 201, and the cables 205 above the vertical wire slots 206 directly enter the vertical wire slots 206 and the underframe 201 through the penetrating openings of the top plate 208 and then enter the control cabinet 204. Because the cable 205 itself is heavy, the bottom of the transverse wiring member 207 is directly supported on the box-dividing housing 202 after the cable 205 is threaded, and no upper limit is required. However, in actual manufacturing, in general, a limit channel 211 is disposed above the transverse wiring member 207, and the limit channel 211 is suspended above the transverse wiring member 207, but does not contact the transverse wiring member 207, so as to limit upward movement of the transverse wiring member 207 and prevent upward movement. Wherein, spacing channel-section steel 211 is fixed on the isolator's of top shell.
In this embodiment, the limiting channel 211 is used to limit the upward movement limit of the transverse wiring member 207, thereby forming a limiting member.
The cable channels formed by the chassis 201, cover plate 209, bottom plate 210, and bottom trunking 212 together in this embodiment communicate with the cubicle 204 and vertical trunking 206, thereby forming a bottom wiring member.
In practical use, the type of the transverse steel beam 2011 may be changed, for example, angle steel, rectangular steel, etc., and the type of the longitudinal steel beam 2012 may be changed.
Specific example 2 of GIS of the present invention:
in embodiment 1, the stopper is a stopper channel steel. In this embodiment, the limiting member may be an L-shaped plate fixed on the top surface of the case division housing, and the lateral wiring member is limited by the lateral edge of the L-shaped plate.
Of course, in actual use, even without the stopper, the lateral wiring member and the cable generally do not move upward under the dead weight of the cable and the lateral wiring member, and therefore the stopper can be eliminated.
Specific example 3 of GIS of the present invention:
in embodiment 1, the bottom surface of the box body of the breaker operating mechanism is slightly higher than the bottom surface of the transverse steel beam, and the box body of the breaker operating mechanism prevents cables from directly penetrating into the control cabinet. In this embodiment, the bottom surface of the box body of the breaker operating mechanism is slightly higher than the top surface of the transverse steel beam, and the cover plate and the bottom plate extend rightward to the right side of the breaker operating mechanism and are connected with the bottom plate at the junction control cabinet, at this time, the cover plate, the bottom plate, the two transverse steel beams and the inner cable channel formed by the longitudinal steel beams together are communicated with the vertical cable slot and the junction control cabinet, and at this time, the bottom cable slot can be canceled.
Specific example 4 of GIS of the present invention:
in embodiment 1, the chassis constitutes a part of the bottom wiring member. In this embodiment, the bottom wiring member may be a main wire slot additionally fixed at the outer side of the chassis, and the cable in the vertical wire slot extends downward and horizontally into the main wire slot, where the main wire slot communicates with the vertical wire slot and the control cabinet.
Concrete example 5 of GIS of the present invention:
in embodiment 1, the transverse wiring member includes a mesh bridge and a slot cover. In this embodiment, the slot cover may be omitted, leaving only the mesh bridge.

Of course, in actual manufacturing, if the space between two adjacent sub-tank housings is large, the external shape of the wire slot may not be designed to be identical to the external shape of the sub-tank housing.
Embodiment 7 of GIS of the present invention:
in embodiment 1, a top plate on the vertical wire slot is provided with a penetrating opening through which a power cable penetrates. In this embodiment, if all the cables are vertically opposite to the transverse wiring member, the through hole in the top plate may be eliminated.
