Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the drawings:

[0019] Such as figure 1 As shown, the present invention requires the following equipment to cooperate and explain, including fixed pulley 1, pulley hook 2, wiring clamp 3, retractable insulating rod 4, ice melting connecting wire 5, winding rope 6, cement rod 7, cross arm 8, insulator 9. , Distribution network wire 10, wiring clamp connection screw 11. When the DC ice melting work is carried out on the overhead line of the distribution network, it is necessary to hook up a connecting wire or a short wire between the DC ice melting power supply and the conductor to be melted. Connect the wiring clamp 3 and the retractable insulation rod 4 through a coil spring and a push-pull rod, install the rope 6 into the groove of the fixed pulley 1, put the pulley hook 2 into the wiring clamp 3, and lift the retractable insulation by hand Pole 4, until the pulley hook 2 is hooked to the cross ...

Abstract

The invention discloses a method for rapidly hitching a power distribution network ice-melting connection lead, which relates to the field of power distribution network direct current ice melting. The method comprises the following steps of (1) fixing a wiring clamp at one end of an insulation rod; (2) mounting a coiling rope on a pulley; (3) lifting the pulley with the insulation rod and hitching the pulley on a cement rod cross-arm; (4) connecting the wiring clamp with one end of the ice-melting connection lead; (5) firmly binding one end of the coiling rope with the ice-melting connection lead; (6) pulling the other end of the coiling rope and lifting the ice-melting connection lead; (7) lifting the ice-melting connection lead below the pulley and fixing the coiling rope; (8) connecting a wiring clamp port with a power distribution network lead; (9) completing hitching of the power distribution network ice-melting connection lead. The method solves a problem that manual wiring through climbing a tower is difficult due to icing, and prevents risks of high-altitude falling of manual wiring.

Description

Technical field [0001] The invention relates to the field of DC ice melting in a power distribution network, and in particular to a method for quickly hooking up a connection wire for ice melting in a power distribution network. Background technique [0002] When the DC ice melting work is carried out on the overhead lines of the distribution network, it is necessary to hook up a connecting wire or a short wire between the DC ice melting power supply and the conductor to be melted. In rainy and snowy weather, the cement poles are slippery and it is very difficult to manually climb the cement pole wiring and there is a risk of falling from high altitude. The DC ice melting output current of the distribution network is large. The ice melting connection wire usually uses a 50 to 70 square millimeter copper wire or multiple parallel wires. The cross-sectional area of ​​the safety grounding wire is also more than 25 square millimeters. A copper wire with a length of 15 meters and a c...
