Embodiment Construction

[0013] As shown in the figure, the live vertical bottle replacement device in the 10kV distribution network includes a multi-layer umbrella-shaped insulator 1. The upper end of the umbrella-shaped insulator 1 is provided with a wire hook 2, and the wire hook 2 is connected to the umbrella-shaped insulator 1. In order to realize relative rotation, a wear-resistant rubber protective layer 3 is set on the surface of the wire hook 2, and a lifting screw 4 is fixed at the lower end of the umbrella-shaped insulator 1. In this embodiment, the lower end of the umbrella-shaped insulator 1 is connected with the lifting screw 4. As a whole, the bottom of the lifting screw 4 is provided with an operating wrench 5, and the lifting screw 4 is threadedly connected with a horizontal U-shaped fixed bracket 6, and a fastening screw 7 is arranged at the bottom of the U-shaped fixed bracket 6.

Abstract

The invention provides a device and method for replacing a charged roller bottle in a 10 kV power distribution network, wherein the device and method are convenient to operate and can improve charged work efficiency. The device comprises a multi-layer umbrella-shaped insulator. A wire hook is arranged at the upper end of the umbrella-shaped insulator and movably connected with the umbrella-shaped insulator. A rubber resistance and protection layer is arranged on the surface of the wire hook. A lifting screw is fixedly connected with the lower end of the umbrella-shaped insulator. An operation spanner is arranged at the bottom of the lifting screw. A U-shaped fixing support is connected to the lifting screw through threads. A fastening screw is arranged at the bottom of the fixing support. During operation, the U-shaped fixing support is fastened to a right-angle cross arm, and the wire hook is rotated to the position below a wire of the roller bottle to be replaced; a screw connected with the wire is detached, the lifting screw is rotated, the wire is lifted up, and a screw fixedly connected with the cross arm is detached; a new roller bottle is fixedly connected with the cross arm, the lifting screw is rotated backward, the fastening screw is released, and the device for replacing the charged roller bottle is detached.

Description

technical field [0001] The invention relates to a device and a replacement method for live vertical bottles in a 10kV power distribution network. Background technique [0002] The vertical bottle is installed on the right-angled crossarm of the overhead pole of the 10kV distribution network. It needs to be replaced in time when it is struck by lightning, mechanical damage, or corrosion. The traditional method is to replace it when the power is off. With the development of science and technology, it has been replaced live. , Protect the phase wire of the pre-replaced vertical bottle with an insulating cover or cover the crossarm with insulating cloth, then remove the wire and place it on the crossarm, and then replace the vertical bottle. Due to the manual operation, the operation procedure is cumbersome, the safety is poor, and the operation efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a li...
