In this embodiment, the circuit breaker includes a three-phase horizontal box casing 202, a main conductor is disposed in the box casing 202, the box casing 202 extends in a horizontal direction (left and right directions in fig. 4), the three-phase box casing 202 is arranged at intervals in a longitudinal direction, and the box casing 202 is supported on a longitudinal steel beam 2012. As shown in fig. 5, the three-phase split case 202 is a middle phase split case 2021 at the middle and side phase split cases 2022 at both sides. In this embodiment, the transverse steel beam 2011 is a transversely extending channel steel, the openings of the two channel steels are arranged in a reverse manner, so that possibility is provided for integral hoisting and transportation of the GIS, and the channel steel comprises an upper wing surface and a lower wing surface; and longitudinal steel beams 2012 are i-beams.
The GIS further comprises a breaker operating mechanism 203 and a control cubicle 204 which are fixed on the underframe 201, the breaker operating mechanism 203 is located between one end of the box separating shell 202 and the control cubicle 204, the GIS further comprises a cable 205, the cable 205 is a secondary control cable, and the cable 205 is connected into the control cubicle 204 from each use part to realize centralized control. Here, the bottom surface of the box of the circuit breaker operating mechanism 203 is sunk to the transverse steel beam 2011 and is higher than the lower wing surface of the transverse steel beam 2011.
In order to lead cables 205 to the control cubicle 204, the GIS further includes a transverse wiring member 207 and a vertical wire slot 206, the structure of the transverse wiring member 207 is as shown in fig. 5, 6 and 8, the transverse wiring member 207 extends along the transverse direction, the transverse wiring members 207 are arranged in two along the longitudinal direction, and the arrangement position of the transverse wiring member 207 is between two adjacent box-dividing housings 202, namely, between the middle box-dividing housing 2021 and the side box-dividing housing 2022. As can be seen from fig. 5, the outer circumferential surfaces of the box-divided housings 202 are circular, and a space is naturally formed between the tops of two adjacent box-divided housings 202, in which the transverse wiring member 207 is located. The transverse wiring member 207 is provided with a wiring channel inside, the cable 205 can transversely pass through the transverse wiring member 207, the transverse wiring member 207 comprises a grid bridge 2071, the grid bridge 2071 extends along the transverse direction, the grid bridge 2071 is of a frame type structure, the shape of the side surface of the grid bridge 2071 is consistent with the shape of the outer peripheral surface of the box separation shell 202, and the grid bridge can be fittingly placed between the two box separation shells 202. The transverse wiring member 207 further includes a slot cover 2072 fastened on the top of the mesh bridge 2071, and the inner edge of the slot cover 2072 has a limit fastener to limit the slot cover 2071 and prevent the slot cover 2072 from loosening and falling off.

As shown in fig. 6, the slot cover 2072 has a plurality of segments, and the adjacent segments are connected by a snap or a buckle for easy assembly and disassembly.
By providing the slot cover 2072, the cable 205 in the mesh bridge 2071 and the mesh bridge 2071 can be protected by being engaged with the outer peripheral surfaces of the two adjacent box casings 202. Since the transverse wiring members 207 are buried in the space between the adjacent two casing housings 202 and cannot be seen from the outside, the overall beauty is improved. As shown in fig. 4, the cable 205 is mostly used above the box casing 202, and an insertion opening is opened in the slot cover 2072 for the cable 205 to pass through in order to allow the cable 205 to enter the transverse wiring member 207 downward.
The GIS further comprises a vertical slot 206, the vertical slot 206 is located at one end of the box-separating housing 202, the vertical slot 206 is communicated with the transverse wiring member 207 and is used for guiding the cable 205 downwards, the structure of the vertical slot 206 can adopt a common slot structure, as shown in fig. 8, one end of the vertical slot 206 is provided with an opening 2061, the opening 2061 is opposite to one end of the transverse wiring member 207, and the cable 205 penetrates through the transverse wiring member 207 and then penetrates into the vertical slot 206 and is guided downwards to extend. In the present embodiment, the number of the vertical wire grooves 206 is the same as the number of the transverse wiring members 207, and both are two. A top plate 208 is fixed on the top of the vertical slot 206, and a through opening is arranged on the top plate 208 for the cable 205 to penetrate.
As shown in fig. 7 and 8, a cover plate 209 is fixedly mounted on the top of the two longitudinal steel beams 2012, the cover plate 209 extends to the circuit breaker actuator 203, and a bottom plate 210 is fixed on the lower wing surface of the longitudinal steel beams 2012, and since the bottom surface of the circuit breaker actuator 203 is higher than the lower wing surface of the longitudinal steel beams 2012, the bottom plate 210 can extend to the bottom of the circuit breaker actuator 203. A closed space is formed as an inner cable passage by the cover plate 209, the bottom plate 210, the longitudinal steel beams 2012, the box of the circuit breaker operating mechanism 203, and the two longitudinal steel beams 2012. Because the box of the circuit 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 two longitudinal steel beams 2012, the bottom wire slot 212 and the longitudinal steel beams 2012 surround to form a closed outer cable channel, and the outer cable channel extends to the junction box 204. In order to connect the inner cable passage inside and the outer cable passage outside, a through-hole is opened in the transverse steel beam 2011 for a cable to pass through. The vertical linear groove 206 is fixed on the cover plate 209, the upper opening of the cover plate 209 is used for the cable 205 to penetrate downwards into the bottom frame 201, and after the cable penetrates into the control cubicle 204, the cable 205 is plugged by fireproof mud after being assembled, so that the control cubicle 204 is ensured to have waterproof performance.
In the invention, cables 205 above the transverse wiring members 207 enter the transverse wiring members 207 and then enter the junction cabinet 204 through the vertical wire grooves 206 and the underframe 201, and the cables 205 above the vertical wire grooves 206 directly enter the vertical wire grooves 206 and the underframe 201 through the through holes of the top plate 208 and then enter the junction cabinet 204. Since the cable 205 itself is heavy, the bottom of the transverse wiring member 207 is directly supported on the box body 202 without being limited above after the cable 205 is threaded. However, in actual manufacturing, the stopper channel 211 is usually arranged above the lateral wiring member 207, and the stopper channel 211 is suspended above the lateral wiring member 207, but does not contact the lateral wiring member 207, and is used to restrict upward movement of the lateral wiring member 207 and prevent upward movement. The limiting channel steel 211 is fixed on the upper shell of the isolating switch.
In this embodiment, the limiting channel 211 is used to limit the upward movement limit of the transverse wiring member 207, so as to form a limiting member.
The cable channel formed by the chassis 201, the cover 209, the bottom plate 210 and the bottom wire slot 212 together in this embodiment communicates with the control cubicle 204 and the vertical wire slot 206, thereby forming a bottom wiring member.
In actual use, the type of the transverse steel beam 2011 may be changed, for example, the transverse steel beam 2011 may be angle steel, rectangular steel, or the like, and the type of the longitudinal steel beam 2012 may also be changed.
The specific embodiment 2 of the wiring structure of the GIS of the present invention:
in embodiment 1, the limiting member is a limiting channel steel. In this embodiment, the limiting member may be an L-shaped plate fixed to the top surface of the box-dividing housing, and the transverse edge of the L-shaped plate limits the transverse wiring member.
Of course, in actual use, even if there is no stopper, the lateral wiring member and the cable do not move upward under the weight of the cable and the lateral wiring member, and therefore, the stopper can be eliminated.
The specific embodiment 3 of the wiring structure of the GIS of the present invention:
in embodiment 1, the bottom surface of the box body of the circuit breaker operating mechanism is slightly higher than the bottom surface of the transverse steel beam, and the box body of the circuit breaker operating mechanism prevents a cable from directly penetrating into the control cubicle. In this embodiment, the bottom surface of the box body of the circuit breaker operating mechanism is slightly higher than the top surface of the transverse steel beam, the cover plate and the bottom plate extend rightwards to the right side of the circuit breaker operating mechanism and are connected with the bottom plate at the control cubicle, at this moment, an inner cable channel formed by the cover plate, the bottom plate, the two transverse steel beams and the longitudinal steel beam is communicated with the vertical linear groove and the control cubicle, and at this moment, a bottom line slot can be cancelled.
The specific embodiment 4 of the wiring structure of the 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 line slot additionally fixed to the outer side of the bottom chassis, the cable in the vertical line slot extends downward and horizontally into the main line slot, and the main line slot communicates the vertical line slot and the control cubicle.
The specific embodiment 5 of the wiring structure of the GIS of the present invention:
in example 1, the transverse wiring member includes a grid bridge and a slot cover. In this embodiment, the slot cover may be eliminated, and only the grid bridge is reserved.
The specific embodiment 6 of the wiring structure of the GIS of the present invention:
in example 1, the transverse wiring member comprises a grid bridge. In this embodiment, the transverse wiring member may be a wire casing fixed in an interval space formed by two adjacent box-dividing housings, and of course, in order to be better inserted into the interval space, a side wall of the wire casing is preferably designed to be arc-shaped and consistent with the outer peripheral shape of the box-dividing housing.
Of course, in actual manufacturing, if the space between two adjacent box shells is large, the shape of the wire slot may not be designed to be consistent with the peripheral shape of the box shell.
The specific embodiment 7 of the wiring structure of the GIS of the present invention:
in embodiment 1, the top plate on the vertical wire groove is provided with a through hole for the cable to penetrate. In this embodiment, if all cables are vertically aligned with the transverse wiring member, the through hole in the top plate may be eliminated.
