Problems solved by technology

Although the above-mentioned traditional ice-melting devices can melt ice, what they don’t know is that: the ice-melting device is easy to cause damage to the high-voltage transmission line, and more importantly, it needs to be powered off first, and then the above-mentioned equipment is installed in the On the power transmission line, it usually takes at least 70 minutes of power outage, and then pushes the gate to send power. After deicing, the above-mentioned equipment needs to be removed after the power outage, and power needs to be sent again, which is time-consuming and labor-intensive, seriously affecting the stability of power supply

The rotating shaft is fitted with a rotating drum 4, and the rotating drum is fitted with rollers. Groove 20 matched with the lead wire 21 after freezing, described drum 4 is connected with drive shaft by transmission mechanism, and the drive shaft of described transmission mechanism and pedal drive mechanism are ...

Embodiment 2

[0056] Embodiment 2 and embodiment 1 difference technical features are:

[0057] The wear-resistant and heat-resistant rubber layer is composed of the following raw materials in parts by weight: 100 parts of nitrile rubber, 20 parts of styrene-butadiene rubber, 5 parts of aluminum oxide, 50 parts of zeolite powder, 10 parts of carbon black N660, ethoxy-modified 11 parts of polytrisiloxane, 6 parts of stearic acid, 7 parts of nylon fiber.

[0058] After the deicing shovel moves upwards, the distance between the blade of the deicing shovel and the groove of the roller is L, and the diameter of the wire after freezing is l, and L-l=3mm.

Embodiment 3 Embodiment 1

[0059] Embodiment 3 Embodiment 1 distinguishing technical feature is:

[0060] The wear-resistant and heat-resistant rubber layer is composed of the following raw materials in parts by weight: 95 parts of nitrile rubber, 15 parts of styrene-butadiene rubber, 4 parts of alumina, 40 parts of zeolite powder, 8 parts of carbon black N660, ethoxy-modified 9 parts of polytrisiloxane, 5 parts of stearic acid, 6 parts of nylon fiber.

[0061] After the deicing shovel moves upwards, the distance between the blade of the deicing shovel and the groove of the roller is L, and the diameter of the wire after freezing is l, and L-l=2mm.

Abstract

The invention discloses a deicing device for an overhead line of a distribution network, which comprises an insulating rod and a housing arranged on the insulating rod, a driving shaft is arranged inside the housing, and a shaft protruding from the housing to move up and down is provided on the housing. The deicing shovel, the drive shaft is provided with an eccentric wheel that drives the deicing shovel to move up and down, the housing is provided with a deicing guiding line protection mechanism, and the deicing guiding line protection mechanism includes a The connecting rod and the rotating shaft arranged at the free end of the connecting rod, the rotating shaft is set with a rotating cylinder, and the rotating cylinder is equipped with a roller, and the peripheral side of the roller is provided with a groove matching the frozen wire. The drum is connected with the drive shaft through a transmission mechanism. The device does not require a power outage during the deicing process, and the high voltage will not cause damage to the operator.

Description

technical field [0001] The invention relates to the technical field of deicing equipment for power transmission lines, in particular to a deicing device and a deicing method for overhead lines of a distribution network. Background technique [0002] With the rapid development of my country's electric power industry, the coverage area of ​​high-voltage transmission network continues to expand, and the lines pass through different geographical environments. Some areas often encounter low temperature, ice, snow or freezing weather. However, since the atmospheric temperature is lower than zero and the air humidity is relatively high, the melted ice will quickly condense into ice, making the speed of freezing faster than the speed of melting, resulting in more and more ice. Severe icing of high-voltage lines will lead to collapse of towers, wire galloping, disconnection, insulator flashover and de-icing jumps, etc., causing accidents such as line tripping and power supply interrup...
