Embodiment Construction

[0008] The present invention includes at least three split spacers and a connecting device for connecting interphase insulators. The connecting device for interphase insulators includes a connecting frame 5 and a connecting plate 6. The connecting plate 6 is provided with a ball head steel sleeve 71 for connecting interphase insulators. .

[0009] In order to further illustrate the present invention, the specific structure of the present invention can be: wire clamp 1 is installed and fixed on the spacer bar support 2 by bolt 4, and rubber post 3 is arranged between wire clamp 1 and bolt 4, and rubber post 3 pairs bolt 4 to the protective effect. In addition, there are six sets of clamps 1 equally distributed in the center of the spacer bracket 2. The interphase insulator connection frame 5 is generally made of aluminum alloy material. One end is fixed on the spacer bracket 2 with bolts 4, and the other end is also fixed with bolts 4. On the connection plate 6, a ball-end ste...

Abstract

The invention relates to a phase spacer, belonging to electric power fittings. The phase spacer comprises a spacer and a connecting device, wherein the spacer is at least divided into three sections;the connecting device is used for connecting interphase insulators; the connecting device for connecting the interphase insulators comprises a connecting frame and a connecting plate; and a ball steelbushing used for connecting the interphase insulators is arranged on the connecting plate. The invention has the advantages of increasing the compensation angle difference between each interphase insulator and a transmission line, keeping the interphase insulators and the transmission line parallel to the maximum extent under the action of external force without distortion, ensuring that the interphase insulators can not shift easily in the ball steel bushing but can rotate 20 degrees in the ball steel bushing when the interphase insulators are connected, and ensuring the safe distance of leads under the action of external force and the weighted rationality of products.

Description

technical field [0001] The invention relates to an electric power fitting, in particular to an interphase spacer bar for a high-voltage transmission line. Background technique [0002] The construction corridor of the high-voltage line is getting smaller and smaller. The 500KV line adopts a compact design. Use three inter-phase spacers to connect with the inter-phase insulators, which requires ensuring the distance between the six conductors of each phase and the safe running distance between the three-phase conductors. However, the current spacer insulators are prone to series movement during the working process, which brings safety hazards to line transmission, causes distortion of interphase insulators and transmission lines, and reduces transmission efficiency. Contents of the invention [0003] In order to overcome the above problems, the present invention provides an interphase spacer that can make the insulator less prone to series movement during the working proce...
