However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0022] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0023] This embodiment provides a gas-insulated switchgear circuit breaker, which is installed on the side of an aluminum plate 100. The gas-insulated switchgear circuit breaker is filled with epoxy resin, and the epoxy resin extends outward through the first mounting base and the second mounting base. This can effectively increase the creepage distance of the gas-insulated switchgear circuit breaker and effectively reduce the phase-to-phase distance of the gas-insulated switchgear circuit breaker, thereby reducing the overall size of the circuit breaker and facilitating the miniaturization design of the gas-insulated switchgear.

[0024] Combination Figures 1 to 4 As shown, the gas-insulated switchgear circuit breaker of this embodiment includes a pole body 10, a vacuum interrupter 11 is provided inside the pole body 10, a first outlet socket 20 and a second outlet socket 30 are provided on the pole body 10, and the first outlet socket 20 and the second outlet socket 30 are both connected to the vacuum interrupter 11. The vacuum interrupter 11 is filled with epoxy resin, and the epoxy resin extends outward after filling the first outlet socket 20 and the second outlet socket 30, with an extension distance of 80-100mm. The epoxy resin in this embodiment can solidify the vacuum interrupter 11, effectively reducing the phase-to-phase distance of the gas-insulated switchgear circuit breaker while ensuring the normal use of the pole body 10, thereby reducing the overall size of the circuit breaker.

[0025] In this embodiment, the first outlet seat 20 is located at the end of the pole body 10, and the second outlet seat 30 is located at the middle section of the pole body 10. The first outlet seat 20 is composed of two opposing arc-shaped sheet-like structures. The first outlet seat 20 is integrally formed at the end of the pole body 10, and the second outlet seat 30 is a columnar structure, integrally formed at the middle section of the pole body 10. In this embodiment, both the first outlet seat 20 and the second outlet seat 30 are integrally formed and installed on the pole body 10. Their structure is stable, and under the premise of satisfying the normal use of the pole body 10 for outlet, it is beneficial to the sealing treatment of the pole body 10.

[0026] Specifically, both the first cable outlet 20 and the second cable outlet 30 in this embodiment are provided with cable outlet holes 70 to guide the wire harness out. The wire harness is guided out through the cable outlet holes 70 to meet the normal use of the pole body 10.

[0027] Furthermore, in this embodiment, the pole body 10 is installed inside the gas box, and one end is connected to the aluminum plate 100 through the sealing screw 40. A corrugated pipe 50 is provided on the aluminum plate 100. The corrugated pipe 50 is connected to the pole body 10 through the connecting rod 60. The corrugated pipe 50 and the pole body 10 are located on both sides of the aluminum plate 100, respectively. The moving contact inside the pole body 10 is pushed by the corrugated pipe 50, so that the moving contact and the stationary contact can perform the opening and closing action, thus meeting the usage requirements of the pole body 10.

[0028] In actual use, the gas-insulated switchgear circuit breaker of this embodiment is installed on the side of the aluminum plate 100. Epoxy resin is filled inside the pole body 10, and the epoxy resin extends outward through the first mounting base and the second mounting base, which can effectively increase the creepage distance of the gas-insulated switchgear circuit breaker, thereby effectively reducing the phase-to-phase distance of the gas-insulated switchgear circuit breaker, thereby reducing the overall size of the circuit breaker, which is beneficial to the miniaturization design of the gas-insulated switchgear.
