500 kilovolt power transmission line spacer electric fixture

Abstract

The invention relates to an electric fixture for a 500-kilovolt power transmission line spacer. At present, clamps used for replacing the spacer in live-line work are all manual, so that the risks are high, the efficiency is low, the structure is complex, the size is large, and the universality is poor. The spacer electric clamp comprises a lead screw body, threads are arranged on the upper portion and the lower portion of the lead screw body respectively, the lower threads are connected with a spacer lower clamp (2), and the upper threads are connected with a spacer upper clamp (4). The left end of the spacer lower clamp and the left end of the spacer upper clamp are connected with spacer upper and lower clamp positioning rods (3) respectively, a ratchet wrench (5) is mounted at the top of the lead screw body, a lead screw wrench (8) is mounted at the bottom of the lead screw body, a ratchet clamp (9) is mounted in a circular hole of the ratchet wrench, and a screw rod clamp (9) is mounted in a circular hole of the lead screw body. And the screw rod wrench is connected with an electric tool (1). The electric fixture is used for the spacer of the 500-kilovolt power transmission line.

Description

technical field [0001] The invention relates to a 500-kilovolt power transmission line spacer electric jig. Background technique [0002] At present, 500kV transmission lines generally use four-split conductors. In order to ensure that the distance between the split sub-conductors remains unchanged to meet the electrical performance and ensure the flow capacity, spacers are installed at a certain distance in the span. Oscillation and breeze vibration can also play a certain inhibitory role, but the current live transmission line conductor spacer tools have disadvantages such as complex structure, bulky size, and poor versatility, resulting in tool portability, inconvenient on-site operation, slow replacement speed, and excessive physical exertion. And other issues. It is of great significance to develop a simple structure, convenient operation, and labor-saving universal tool for replacing wire spacers with live wires, which is of great significance to ensure the safe and s...

Problems solved by technology

[0005] 2. In view of concentrated problems such as product quality and equipment aging, use the power outage maintenance plan to replace the spacer rods on the entire transmission line or a certain section. In the process, different design units, construction units and manufacturers are used respectively, resulting in various types and models of transmission line spacers being transported, and even different types and models of spacers on the same transmission line or within the same span. For the installation and replacement of different types of spacers, the operation and maintenance unit usually designs, orders, and purchases corresponding different types of spacer fixtures, which increases the production cost of maintenance work. In the maintenance work of 500 kV transmission line spacers During the process, the operators need to carry a variety of different types of spacer fixtures according to the work tasks to carry out maintenance operations such as climbing the tower and wiring, which increases the complexity and labor intensity of the maintenance operations, and reduces the safety factor and work efficiency of the maintenance operations.

[0008] 1. During the tightening process of some traditional spacer replacement operation tools, the operators are time-consuming and laborious;

[0009] 2. In the construction and maintenance work on the transmission line, the working space will be very narrow, and the body position is not easy to adjust. The existing tools are also too large in length and volume. Operators need to frequently change their body positions during operation, thus wasting a lot of physical strength ;

[0010] 3. Reducing the burden of workers working at heights is an important principle in the design of tools for working at heights. Because some tool manufacturers do not know enough about on-site operations, the existing special tools have excessively increased the size in some links during design;

[0011] 4. The reliability of tools is also an important principle in the design of high-altitude tools. If the tools are damaged or fall off during high-altitude operations, the work will be terminated, and it will pose a serious threat to the life safety of ground personnel, and the existing traditional special tools often There will be problems such as lack of physical strength and increased labor intensity during use
