[0038] Embodiment 1:

[0039] See also Figure 1 to Figure 7 The utility model discloses a 10 kV switch cabinet busbar bushing insulation fixing device, comprising a switch cabinet wall 1, a rubber sleeve head 2 fixedly installed on the front side of the switch cabinet wall 1, a quick-install and quick-release device 3 fixedly installed on the rear side of the switch cabinet wall 1, a plastic retaining tube 4 slidably embedded in the quick-install and quick-release device 3, a circular groove 5 arranged in the middle of the plastic retaining tube 4, a locking device 6 installed at the front end of the plastic retaining tube 4, and a switch cabinet busbar 7 passing through the locking device 6.

[0040] The quick-loading and quick-releasing device 3 includes: openings 32 are arranged on the left and right sides of the outer wall of the quick-loading and quick-releasing device shell 31, a connecting ring 33 is slidably sleeved on the outer diameter surface of the quick-loading and quick-releasing device shell 31, an embedding groove 34 is arranged inside the quick-loading and quick-releasing device shell 31, one end of a drawstring 35 is fixedly connected to the inner side of the connecting ring 33, and the drawstring 35 passes through the opening 32, a spring block 36 is fixedly connected to the inner side of the embedding groove 34, the outer side of a bite block 37 is fixedly connected to the end of the spring block 36, the bite block 37 is slidably embedded in the embedding groove 34, and the other end of the drawstring 35 is fixedly connected to the outer diameter of the bite block 37.

[0041] The quick-install and quick-release device 3 can quickly connect the plastic retaining tube 4 with the rubber sleeve 2, and the quick-install and quick-release device 3 is made of high-temperature resistant composite plastic material to prevent the device from being melted by high temperature caused by leakage, resulting in the device being unable to be used normally.

[0042] The working principle of a 10 kV switch cabinet busbar bushing insulation fixing device based on Example 1 is: the staff first fixes the rubber sleeve 2 on the front side of the busbar opening of the switch cabinet wall 1, then connects the quick-install and quick-release device 3 to the rear side of the busbar opening, and then inserts the plastic retaining tube 4 into the rubber sleeve 2. In the process of the plastic retaining tube 4 entering the quick-install and quick-release device 3, the plastic retaining tube 4 first presses the bite block 37 into the embedded groove 34, and then when the bite block 37 reaches the position of the circular groove 5, the bite block 37 is pressed into the circular groove 5 by the spring block 36 on the outside of the bite block 37, so that the plastic retaining tube 4 and the rubber sleeve 2 are connected. When the plastic retaining tube 4 needs to be taken out and replaced, the connecting ring 33 is pulled backward, and the connecting ring 33 drives the drawstring 35 to make the bite block 37 connected to the drawstring 35 re-embedded in the embedded groove 34, and then the staff can manually pull out the plastic retaining tube 4.

[0043] Embodiment 2:

[0044] See also Figure 1 to Figure 7 , a 10 kV switch cabinet busbar bushing insulation fixing device of the utility model, compared with the first embodiment, this embodiment also includes: the locking device 6 includes, the locking device shell 61 is fixedly connected to the front end of the plastic retaining tube 4, the slide groove 62 is arranged inside the locking device shell 61, the threaded hole 63 is arranged at the top of the locking device shell 61, the clamping block 64 is slidably embedded in the slide groove 62, the connecting rod 65 is fixedly connected to the top surface of the clamping block 64, the bottom end of the spring 66 is fixedly connected to the top surface of the clamping block 64, the top end of the spring 66 is fixedly connected to the top of the inside of the locking device shell 61, and the bolt 67 is threadedly connected to the inside of the threaded hole 63.

[0045] The locking device 6 is used to fix the switch cabinet busbar 7 to prevent the switch cabinet busbar 7 from sliding freely inside the rubber sleeve 2 and the plastic retaining tube 4, causing the connection of the switch cabinet busbar 7 to become loose.

[0046] In this embodiment: after the staff installs the plastic retaining tube 4, the staff passes the switch cabinet busbar 7 through the plastic retaining tube 4. After the busbar is connected to the internal circuit of the switch cabinet, the staff connects the bolt 67 with the threaded hole 63 at the top of the locking device housing 61, and tightens the bolt 67. During the tightening process of the bolt 67, the bottom of the bolt 67 presses against the connecting rod 65. The connecting rod 65 drives the clamping block 64 to move downward inside the slide groove 62 under the push of the bottom of the bolt 67, and finally supports the switch cabinet busbar 7 inside the plastic retaining tube 4. When it is necessary to replace the plastic retaining tube 4, the bolt 67 is rotated in the opposite direction to make the bolt 67 come out of the threaded hole 63. At the same time, the clamping block 64 returns to its original position under the pulling force of the spring 66, and the locking of the switch cabinet busbar 7 is released.

[0047] The utility model provides an insulation fixing device for a busbar bushing of a 10 kV switch cabinet through improvement, wherein a quick-install and quick-release device 3 is arranged on the back of a switch cabinet wall 1, a locking device 6 is arranged on the front end of a plastic retaining tube 4, and a spring block 36 on the outer side of the bite block 37 is used to press the bite block 37 into the inside of a circular groove 5, so that the plastic retaining tube 4 can be quickly docked with the rubber sleeve 2, and the clamping block 64 is driven by the bottom of the bolt 67 to move downward in the slide groove 62 to support the switch cabinet busbar 7 inside the plastic retaining tube 4, so as to prevent the switch cabinet busbar 7 from sliding freely inside the rubber sleeve 2 and the plastic retaining tube 4.
