A high stability cable fixing bracket

Abstract

The invention provides a high-stability cable fixing bracket. The lower end of a first insulating column and the lower end of a second insulating column are provided with buffer mechanisms respectively; each buffer mechanism comprises a first mounting shaft, a mounting sleeve, an elastic plate and a supporting plate, wherein the mounting sleeve is mounted at the bottom of the first insulating column, the first mounting shaft is mounted in the mounting sleeve, the supporting plate is installed at one end of the first mounting shaft which is far away from the mounting sleeve, and the mounting sleeve is connected with the supporting plate through the elastic plate; the mounting sleeve is provided with a first limiting plate; the first limiting plate is provided with a first piston shaft; thefirst piston shaft is provided with a first piston; the first piston is provided with a second mounting shaft; the second mounting shaft is mounted at the upper end of the supporting plate; and a first spring located between the first limiting plate and the second mounting shaft sleeves the outer peripheries of the first piston shaft and the first piston. With the high-stability cable fixing bracket of the invention adopted, sufficient stable support can be provided for a cable during the mounting, supporting and fixing of the cable, and support stability decrease caused by the impact force ofthe cable applied to the bracket due to the gravity of the cable can be avoided.

Description

technical field [0001] The invention relates to a cable fixing device, in particular to a high-stability cable fixing bracket. Background technique [0002] With the acceleration of power grid construction, more and more ring network cabinets are used. The cable room of the commonly used SF6 gas-insulated common box ring network cabinet is air-insulated, and is connected to the cable through the T-shaped and elbow-shaped terminals of the cable. Outlet bushing, due to the compact space and the use of three-phase cables, the cable cannot be substantially fixed, the vertical stress of the cable's own weight is transmitted to the bushing, and the electric power of the short-circuit current will be transmitted to the bushing during operation, resulting in the air chamber of the ring network cabinet The failure caused by the leakage, resulting in a huge power accident. However, the current cable fixing brackets in the prior art have poor stability, and the cushioning and shock ab...

[0002] With the acceleration of power grid construction, more and more ring network cabinets are used. The cable room of the commonly used SF6 gas-insulated common box ring network cabinet is air-insulated, and is connected to the cable through T-shaped and elbow-shaped terminals. Outlet bushing, due to the compact space and the use of three-phase cables, the cable cannot be substantially fixed, the vertical stress of the cable's own weight is transmitted to the bushing, and the short-circuit current electromotive force will be transmitted to the bushing during operation, causing the air chamber of the ring network cabinet to The failure caused by leakage, resulting in a huge power accident

However, the cable fixing brackets in the prior art have poor stability, and the cushioning and shock absorption effects cannot meet the needs of actual use.
