Embodiment 1

[0024] Example 1: Reference Figure 1-4 . The interphase spacer spring damping device includes a piston-type shaft rod 1 with a flat connecting foot 10 at the bottom, a semi-cylindrical body I2 and a semi-cylindrical body II3 with a groove-shaped flat foot 12 on the symmetrical top, an upper spring 4, Lower spring 5, some fastening bolts 6 and rubber sealing gasket 7 etc. Among them, the half-cylinder I2 and half-cylinder II3 are located at the top, and the piston shaft 1 is located at the bottom to avoid corrosion of the upper spring 4 and the lower spring 5 due to water ingress. The piston shaft 1 is composed of a piston 8, a cylindrical shaft 9, a flat Connecting foot 10, screw hole Ⅱ 11, half cylinder Ⅰ 2 and half cylinder Ⅱ 3 are composed of groove flat foot 12, screw hole Ⅰ 13, screw hole Ⅱ 14 and small semi-cylindrical fixed shaft hole 15, small semi-cylindrical fixed shaft hole 15 Ensure that the piston-type shaft 1 with flat feet is displaced in the axial direction,...

Abstract

The present invention relates to a phase-to-phase spacer spring damping device which is especially suitable for a 35kV and above overhead transmission line, belonging to the technical field of power industry overhead transmission line equipment. The device comprises a spring cylinder with an upper spring and a lower spring inside. The top of the spring cylinder is provided with an upper connection piece for connecting a phase-to-phase spacer composite insulator. The upper spring and the lower spring are vertically arranged in the spring cylinder which is formed by a half cylinder I and a half cylinder II which are connected. The bottom of the spring cylinder is provided with a through hole for passing a piston type shaft rod which comprises pistons arranged at two ends of the shaft rod and a lower connection piece for connecting a line fitting. The pistons are in the spring cylinder and are between the upper spring and the lower spring, and the lower connection piece is outside the spring cylinder. The phase-to-phase spacer spring damping device has a rainproof function, a spring pressing function and a spring pulling function.

Description

technical field [0001] The invention relates to an interphase spacer bar spring damping device, which is especially suitable for use in overhead transmission lines of 35kV and above, and belongs to the technical field of overhead transmission line equipment in the electric power industry. Background technique [0002] In the windy season, when the wind blows to the wires of the transmission line of the power system, a certain amount of power will be generated, which will induce a self-excited vibration of the wires and galloping. At this time, it is necessary to use a A spacer bar with insulation and mechanical strength, the spacer bar mechanically connects the wires, so that the movement of the wires is mutually restricted, so as to achieve the purpose of suppressing galloping. [0003] At present, some anti-dancing devices and spacers have appeared on the market. For example, the patent name is: a damping type anti-dancing device, and the publication number is: 201781254U...
