Abstract

The invention provides a wheel type bracket for a bypass flexible cable of a power distribution network and a method for fixing a residual cable. The wheel type bracket comprises an insulating bracketand a fixed base, wherein the insulating bracket is detachably connected with the fixed base; when the wheel type bracket is installed, the fixed base is fixed on an electric pole and then the insulating bracket is installed to allow the installation of the wheel type bracket to be easier and more save labor; the insulating bracket comprises a reel, the reel is provided with three annular groovesrespectively configured to allow three single-phase bypass cable to wind so as to avoid that different-phase flexible cables are extruded together and the insulation between phases is damaged due toover-current and overheat to cause interphase short circuit and improve the use safety of the wheel type bracket, and the fixed base comprises a chain cooperated with the electric pole and a locking device configured to lock the chain and the electric pole. The method for fixing a residual cable employs the wheel type bracket to make installation and operation of the wheel type bracket simple andlabor-saving, and the fixing of the residual cable is much safer and more reliable.

Description

technical field

[0001] The invention relates to the technical field of cable brackets, in particular to a wheeled bracket used for distribution network bypass flexible cables and a method for fixing residual cables. Background technique

[0002] With the continuous development of my country's economy, urban construction has brought great challenges to the stability of electric energy. Users' requirements for continuous power supply are increasing day by day, and the live bypass operation of the distribution network can be connected to the distribution network through the access of bypass equipment. The load in the power grid is transferred to the bypass system to realize power outage maintenance of the equipment to be repaired and maintain uninterrupted power supply to users, and is widely used in the maintenance work of the distribution network. The safety and reliability of the bypass system during operation is the key to live bypass operation of the entire distribution net...
