Secondary control cable fixing bracket

Abstract

The invention discloses a secondary control cable fixing bracket, which is characterized in that it comprises a bottom fixing splint (1), a middle fixing splint (2), a top fixing splint (3), a bottom fixing splint (1) and a top fixing splint ( 3) There are evenly distributed semicircular cable fixing grooves (4) on the inner side, and evenly distributed semicircular cable fixing grooves (4) are arranged on both sides of the middle fixing splint (2). There is a cable fixing inner bushing (7), the middle fixing splint (2) and the top fixing splint (3) are connected to the cable sign hanging bracket (5) through the bracket mounting hole (8), and the cable sign hanging bracket (5) There is an arc-shaped groove (9), and the arc-shaped groove (9) is connected to the cable sign (10). The present invention is simple in structure, easy to use, safe and reliable, wide in scope of application, low in cost, and improves the operation stability of the power grid. Improve economic efficiency.

Description

Technical field: [0001] The invention relates to a secondary control cable fixing bracket, which belongs to the field technical field of cable laying. Background technique: [0002] In the daily substation installation and technical renovation process, it is necessary to connect a large number of secondary cables in the control panel. When the secondary cables are not neatly arranged or crossed, it will cause eddy current loss and increase the difficulty of finding cables during maintenance work. At present, the secondary cables are generally fixed in the control panel by plastic cable ties. The cable ties are very easy to age and break. The secondary cables will fall off from the terminal strip due to external force or self-weight, resulting in the protection device not operating or refusing to operate, resulting in grid accidents. It not only increases the instability of power grid operation and the work difficulty of maintenance personnel, but also wastes a lot of manpow...

When the secondary cables are not neatly arranged or crossed, it will cause eddy current loss and increase the difficulty of finding cables during maintenance work

At present, the secondary cables are generally fixed in the control panel by plastic cable ties. The cable ties are very easy to age and break. The secondary cables will fall off from the terminal strip due to external force or self-weight, resulting in the protection device not operating or refusing to operate, resulting in grid accidents. This not only increases the instability of power grid operation and the work difficulty of maintenance personnel, but also wastes a lot of manpower and material costs; and the cable label is directly tied to the lower end of the cable, the cable tie is aging and easy to break, and it is inconvenient to find and easy to make mistakes
