The invention discloses a high-voltage wire freezing and snowing alarm device and an alarm method thereof. The high-voltage wire freezing and snowing alarm device is fixedly arranged at the upper partof a high-voltage wire iron tower, and when a high-voltage wire is frozen, a wire sample can also be frozen with the same thickness, then traction force of a force transmission wire subjected by thewire sample can be increased, a spring can be stretched under the action of the traction force, a contact in a signal converter can move downwards, a voltage signal introduced into an electromagneticwave transmitting device can change, the signal is loaded to an electromagnetic wave signal to be transmitted, a receiving device at a controlled place receives the electromagnetic wave signal, and the signal is processed so as to provide conditions of high-voltage wire freezing of a installation place of the device for personnel at the controlled place. In the invention, freezing conditions of various places of transmission lines can be automatically, accurately and conveniently known at any times and any places, and preparation for taking various protective measures can be made in time. Having low cost and using a very mature technology, the device is easy to be realized and has wide market prospect.
Description
Technical field: [0001] The invention belongs to the field of electric equipment, and relates to an alarm device and an alarm method, in particular to an alarm device for icing and snow on high-voltage lines and an alarm method thereof. Background technique: [0002] At the beginning of last year, the southern part of my country suffered a rare ice and snow disaster, which had a serious impact on the national economy and people's production and life. Because high-voltage wires are all on high iron towers, and many iron towers are in mountainous areas, the traffic is inconvenient, which makes it difficult for people to know the freezing situation of high-voltage wires in time. Accurate information about the icing of wires is often only known when the wires are broken by thick ice and snow and cause power outages. For example, icing thickness. There is no device on the market that can automatically, timely and accurately report the degree of icing or snow accumulation on ele...
