Description

Technical Field

[0001] The utility model relates to a switch tension spring assembly for high-voltage opening. Background Art

[0002] The switch spring assembly for high-voltage switch opening is an energy storage component. It is compressed when the high-voltage switch is closed and maintained in the energy storage state. When the switch needs to be opened, the relevant mechanism releases the switch spring instantly, driving the opening mechanism to operate and open the switch at a certain speed. The service life of the existing switch spring for opening is short. After analysis, it is mainly caused by the following problems: 1. There is no guide device when the spring is in action, which makes it move more when it is in action, and frequent actions can easily cause the spring to be damaged; 2. The frequent stretching and release process of the spring has a large impact force, which makes the surface of the spring itself wear and tear more, but there is no buffering and lubrication, so improvements and optimizations are made for this.

[0018] like Figure 1-5As shown, the utility model relates to a switch spring assembly for high-voltage disconnection, comprising a switch spring 1 and a guide cylinder assembly 2 sleeved outside the switch spring 1, wherein the guide cylinder assembly 2 comprises an inner cylinder 4, an action cylinder 5 arranged at both ends of the inner cylinder 4 and connected to the switch housing, a sponge sleeve 6 and an oil storage rubber sleeve 7, wherein the inner cylinder 4 comprises an inner cylinder body 9 and a limit screw 10, wherein an inner cylinder through hole 11 is provided in the inner cylinder body 9, wherein the limit screw 10 is penetrated through the inner cylinder body 9 and is vertically arranged with the inner cylinder through hole 11, wherein the inner cylinder body 9 is provided with an inner cylinder docking hole 12, wherein the sponge sleeve 6 is sleeved on the switch spring 1 and is placed in the inner cylinder through hole 11; wherein the action cylinder 5 comprises an action cylinder body 14, wherein the action cylinder 5 is provided with an action cylinder through hole 15 and a stop screw 10 which is connected with the inner cylinder through hole 11; wherein the stop screw 10 ... stop screw 10 is provided with an inner cylinder docking hole 12, wherein the stop screw 10 is provided with an inner cylinder docking hole 12, wherein the stop screw 10 is provided with an inner cylinder docking hole 12, wherein the stop screw 10 is provided with an inner cylinder docking hole 12, wherein the stop screw 10 is provided with an inner cylinder docking hole 12, wherein the stop screw 10 is provided with an inner cylinder docking hole 12, wherein the The waist-shaped action port 16 corresponding to the limit screw 10, the oil storage rubber sleeve 7 is sleeved outside the inner cylinder body 9 and placed in the action cylinder through hole 15, the oil storage rubber sleeve 7 is hollow inside, and is provided with an oil storage cavity for storing lubricating oil, the inner wall of the oil storage rubber sleeve 7 is provided with an oil outlet column 26 arranged through the inner cylinder docking hole 12, and the front end of the oil outlet column 26 is provided with an oil outlet 17 connected to the oil storage cavity and docked with the sponge sleeve 6. The inner cylinder 4 and the action cylinder 5 cooperate with each other to enable the switch tension spring 1 to have a guiding effect during the stretching and contraction process, the sponge sleeve 6 can reduce the movement of the switch tension spring 1 when it is actuated, and the oil storage rubber sleeve 7 transfers the lubricating oil to the switch tension spring 1 through the sponge sleeve 6 to reduce wear and friction, thereby increasing the service life of the switch tension spring 1.

[0019] The inner diameter of the sponge sleeve 6 is the same as the outer diameter of the switch tension spring 1 , and the sponge sleeve 6 can contact the switch tension spring 1 , so that the lubricating oil can lubricate the switch tension spring 1 more smoothly and can also better reduce the movement of the switch tension spring 1 during operation.

[0020] The limit screw 10 and the inner cylinder docking hole 12 are respectively arranged at intervals around the inner cylinder body 9, and the arc angle between the limit screw 10 and the inner cylinder docking hole 12 is 90°, which prevents the action cylinder 5 from affecting the oil output of the oil outlet column 26 when it is in action, making the action more stable and reliable.

[0023] Inner cylinder ribs 21 are disposed at both ends of the inner cylinder body 9 at the inner cylinder through hole 11 to effectively limit the sponge sleeve 6 .

[0024] During the stretching and contraction process, the switch tension spring 1 will cause the operating cylinder 5 connected to the switch housing to move accordingly. When the operating cylinder 5 moves, it will squeeze the oil storage rubber sleeve 7 placed therein, so that the lubricating oil in the oil storage rubber sleeve 7 flows out from the oil outlet 17 at the front end of the oil outlet column 26 and penetrates into the sponge sleeve 6. The sponge sleeve 6 keeps in contact with the switch tension spring 1, thereby transferring the lubricating oil to the switch tension spring 1, so that the switch tension spring 1 is lubricated.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention are included in the protection scope of the present invention.
