Embodiment Construction

[0044] In order to solve the problems existing in the prior art, an embodiment of the present invention provides a monitoring device for the amount of ice coating on wires.

[0045] Such as figure 1 As shown, a monitoring device for the amount of icing on wires provided by an embodiment of the present invention includes:

[0046] Test leads 106;

[0047] Two parallel vertical connecting rods 104 are vertically fixedly connected with the test leads 106;

[0048] The vertical elastic part 103, the upper end is fixed with the upper end of the vertical connecting rod 104, and the position of the lower end is fixed, and is used for receiving the vertical connecting rod 104 when the test wire 106 moves down following the ice-coated heavy pressure. The vertical pressure exerted by the rod 104 produces deformation;

[0049] The displacement sensor 102 is used for measuring deformation.

[0050] Wherein, the material and structure of the test wire 106 are the same as that of the ac...

Abstract

The invention provides a wire ice cover monitoring device, solving the problems that the existing wire ice cover monitoring device is difficult to manufacture and has low safety factor. The wire ice cover monitoring device comprises a tested wire, two vertical connecting rods, a vertical elastic component and a displacement sensor, wherein the two vertical connecting rods are in parallel and are vertically and fixedly connected with the tested wire; the upper end of the vertical elastic component is fixed with the upper ends of the vertical connecting rods, the lower end of the vertical elastic component is fixed, the vertical elastic component is used for receiving vertical pressure applied by the vertical connecting rods when the vertical connecting rods move down followed by the tested wire which is under the ice cover pressure so as to generate a deformation variable; and the displacement sensor is used for measuring the deformation variable. Through the technical scheme, the ice covering on the running wire can be subjected to effective on-line monitoring, and the wire ice cover monitoring device has the advantages of simple structure and high safety factor and is convenient to use and easy to maintain.

Description

technical field [0001] The invention relates to the monitoring of high-voltage power supply, in particular to a monitoring device for the amount of ice coating on wires. Background technique [0002] Regardless of whether in mountainous areas or plain areas, the conductors of transmission lines will be covered with ice in spring and winter, and the dancing under the action of wind will cause great damage to high-voltage transmission lines, resulting in frequent occurrence of ice disasters, such as Ice flash, wire whipping, tower tilting, even tower toppling, wire grounding, etc., seriously threaten the safe operation of power devices. [0003] The conductors of transmission lines may form ice coatings when the temperature and humidity of the air reach a certain level, and the wind speed and direction are different, and the speeds of ice formation are also different. Generally, the wind speed is faster when the wind direction and the direction of the conductors are closer to ...
