Description

Technical Field

[0001] The utility model belongs to the technical field of power systems, and in particular relates to an outdoor aging platform for insulators of a power system. Background Art

[0002] Insulators, commonly known as porcelain bottles, are used to support conductors. They play two fundamental roles in overhead transmission lines: supporting the conductors and preventing current from returning to the ground. During operation, the silicone rubber outer insulation of composite insulators is directly exposed to the atmosphere and is susceptible to weathering, leading to aging issues. Therefore, outdoor testing is necessary to monitor the potential impact of the atmospheric environment on the silicone rubber outer insulation.

[0003] After the current test platform is built, it is necessary to use tools such as ladders to remove the insulator samples from the high test platform and send them to the laboratory for aging analysis. Since it is necessary to study the impact of different aging times on the insulators, multiple sampling is required, which is not very convenient. In addition, high-altitude sampling also poses safety issues. Summary of the Invention

[0004] The main purpose of the utility model is to provide an outdoor aging platform for insulators in a power system, aiming to achieve safe and convenient sampling.

[0005] To this end, the utility model provides an outdoor aging platform for insulators in a power system, comprising a column, an insulator mounting platform and a lifting assembly, wherein the column is fixedly mounted on the ground, the insulator mounting platform is mounted on the column, and the lifting assembly is used to achieve the lifting of the mounting platform;

[0006] The lifting assembly includes a lifting rope, a slider, pulley 1 and pulley 2. A vertically extending sliding cavity is provided in the column, and the sliding cavity passes through the top of the column. The slider is slidably installed in the sliding cavity. The side of the column is provided with a sliding groove which is connected to the sliding cavity and extends in the same direction. The mounting platform is fixedly connected to the slider after passing through the sliding groove. Pulley 1 and pulley 2 are fixedly installed on the top of the column. One end of the lifting rope is fixedly connected to the top of the slider, and the other end is fixed to the bottom of the column after passing through pulley 1 and pulley 2.

[0019] See also Figure 1-Figure 3 An outdoor aging platform for insulators in an electric power system includes a column 1, an insulator mounting platform 2 and a lifting component 3. The column 1 is vertically fixed on the ground, the insulator mounting platform 2 is installed on the column 1, and the lifting component 3 is used to realize the lifting of the mounting platform.

[0020] Among them, the lifting assembly 3 includes a lifting rope 301, a slider 302, a pulley 1 303 and a pulley 2 304. A vertically extending sliding cavity 4 is provided in the column 1. The sliding cavity 4 passes through the top of the column 1. The slider 302 is slidably installed in the sliding cavity 4. The side of the column 1 is provided with a slide groove 5 which is connected to the sliding cavity 4 and extends in the same direction. The mounting platform is matched and passed through the slide groove 5 and is fixedly connected to the slider 302. Pulley 1 303 and pulley 2 304 are fixedly installed on the top of the column 1. One end of the lifting rope 301 is fixedly connected to the top of the slider 302, and the other end is fixed to the bottom of the column 1 after passing around pulley 1 303 and pulley 2 304. The sliding cavity 4 and the slide groove 5 both extend to the bottom position of the column 1.

[0021] When an outdoor aging test is required, the insulator sample 6 is first fixedly installed on the installation platform, and then the lifting rope 301 is pulled downward to drive the slider 302 to move upward along the column 1, and the insulator installation platform 2 is lifted to the set height. The lifting rope 301 is fixed on the column 1, and the position of the insulator installation platform 2 can be fixed. The outdoor aging test is performed on the insulator sample 6. When the set aging time is reached, the lifting rope 301 is released, and the slider 302 slides slowly downward along the column 1, and the insulator installation platform 2 is lowered to the set position, so as to facilitate the sampling operation of the staff. After the sampling is completed, the installation platform is lifted to the set height again, and the remaining samples can be subjected to a longer aging test. During the entire sampling process, there is no need to set up a ladder for high-altitude work, and the operation is convenient and safe.

[0022] See also Figure 1 In some embodiments, a reel 7 is rotatably provided at the bottom of the column 1, and a lifting rope 301 is wound around the reel 7. A positioning through-hole is provided on the reel 7, and a socket corresponding to the positioning through-hole is provided on the column 1. The positioning rod 8 is matched with the positioning through-hole and inserted into the socket. In this embodiment, after the installation platform is lifted to the desired height, the position of the reel 7 can be fixed by inserting the positioning through-hole and the socket. At this time, the reel 7 cannot rotate around its own rotation axis. The lifting end of the lifting rope 301 is fixed to the column 1 to keep the installation platform in the set position. When the installation platform needs to be lowered, the positioning rod 8 is pulled out of the positioning through-hole, and the reel 7 is rotated, so that the slider 302 slides downward in the sliding cavity 4 under the action of its own gravity, and the installation platform can be lowered.

[0023] See also Figure 1 and Figure 2 It is understood that in order to accurately lift the mounting platform to the desired height, a height scale line 9 can also be provided on the column 1. To prevent the slide 302 from rapidly descending on the column 1 due to improper lowering operation and causing damage to the specimen, a buffer spring 10 is provided at the bottom of the sliding cavity 4. A buffer plate 11 is fixedly mounted on the top of the buffer spring 10. The buffer spring 10 and the buffer plate 11 cushion the slide 302 and protect the mounting platform. The buffer plate can be made of a flexible material such as rubber.
