Device for online warning freezing and swing of transmission line

Abstract

The present invention discloses an online early warning device of the ice coating and throwing about the electric transmission line. The early warning device consists of a data collecting terminal, a wireless communication base station and a specialist analyzing device. The data collecting terminal includes a solar battery board for charging the storage battery, and the insulator collecting signals are input into each sensor, a pretreatment unit, a central data processing unit, a transmitting and receiving unit of a wireless communication base station, a transmitting wireless communication device, a transmitting and receiving unit and a computer of the specialist analyzing device. The combination of the units is reasonable and the using of the device is convenient, the data is transmitted through the wireless relay, GSM, CDMA network and the security of the line is known by combining the parameters of the spot image, the temperature, the humidity, the wind speed, the wind direction and the weight of the guide line and the extent of throwing about. The over-standard electric transmission line is alarmed in time for directing the examining, repairing and preventing. 50-20000Hz signals can be detected; the power consumption is 3mA; the manpower, material resources and time can be saved and the device can be widely used on the high-pressure electric transmission lines.

Description

technical field [0001] The invention relates to high-voltage power supply monitoring, and is especially suitable for an on-line early warning device for icing and galloping of power transmission lines. Background technique [0002] Regardless of whether in mountainous areas or plain areas, the conductors of transmission lines in spring and winter will be covered with ice, and they will dance under the action of wind, causing great damage to high-voltage transmission lines, resulting in frequent occurrence of ice disasters, such as Ice flash, wire whipping, tower tilt, and even the tower toppled wire grounding, etc., seriously threaten the safe operation of power devices. [0003] The icing of the conductors of the transmission line can only be formed under specific natural environmental conditions. After long-term research and experiments by relevant units, the following conclusions can be concluded: when the temperature and humidity of the air reach certain conditions, icin...

[0002] Regardless of whether in mountainous areas or plain areas, the conductors of transmission lines in spring and winter will be covered with ice, and they will dance under the action of wind, causing great damage to high-voltage transmission lines, resulting in frequent occurrence of ice disasters, such as Ice flash, wire whipping, tower tilt, and even the tower toppled wire grounding, etc., seriously threaten the safe operation of power devices

[0003] The icing of the conductors of the transmission line can only be formed under specific natural environmental conditions. After long-term research and experiments by relevant units, the following conclusions can be concluded: when the temperature and humidity of the air reach certain conditions, icing can be formed. And the wind speed and direction are different, and the speed of ice formation is different. Generally, the closer the wind direction and the direction of the wire are to vertical, the faster the wind speed is, and the faster the speed of ice formation is; when the temperature and humidity meet the conditions, the formation of ice The amount depends on the wind speed. When there is no wind or light wind, only very thin ice can be formed. When the wind speed reaches a certain speed, the ice on the conductor will accumulate and thicken, and the conductor will rotate under the action of wind A flat-shaped ice coating is formed, which accumulates thicker and thicker, and finally forms a jagged ice coating. At this time, accidents such as ice flashes, wind whips, and even towers tilting and collapsing to the ground are extremely prone to occur!
