[0025] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] See Figure 1-5 A GCB arc extinguishing chamber moving arc contact fixing device includes a base 10, two support plates 20 are provided on the upper side of one end of the base 10, and an operating space 21 is defined between the two support plates 20. A support frame 30 is provided on the upper side of the other end of the base 10, and a limiting groove 31 is provided on the upper side of the support frame 30. A first mounting hole 23 and a first threaded hole 24 are provided on the support plate 20. Figure 4 The first mounting hole 23 is used to connect and fix with the flange of the GCB arc extinguishing chamber moving arc contact 40 head by bolts, see Figure 5 The first threaded hole 24 is used to install the limit bracket 50 via a bolt, and the tail of the GCB arcing chamber moving arc contact 40 is placed on the support bracket 30. Through the above structure, the GCB arcing chamber moving arc contact 40 can be fixed, and the interior of the GCB arcing chamber moving arc contact 40 can be easily disassembled and repaired through the operating space 21.

[0027] In this embodiment, the installation limit frame 50 is used to limit and fix the tool for removing the protective cover. One end of the tool for removing the protective cover is plugged into the protective cover, and the other end extends out of the hole on the limit frame 50, making it easy to twist the tool for removing the protective cover with a wrench.

[0028] In this embodiment, see Figure 1 The base 10 includes a first support plate 11, a second support plate 12, and a connecting rod 13.
