Overhead power transmission line icing thickness detection device

Abstract

The invention discloses an ice coating thickness detection device for an overhead power transmission line, comprising: a signal transmitter, a signal receiver 1, a signal receiver 2, an arithmetic circuit, a distance sensor and a timer; the signal transmitter emits an acoustic signal The signal receiver one receives the reflected signal of the acoustic signal; the signal receiver two receives the acoustic signal; the distance sensor measures the distance between the signal transmitter and the signal receiver two The timer is connected to the signal transmitter, the signal receiver one and the signal receiver two, the timer records the signal sending and receiving time, and the operation circuit is connected to the distance sensor and the timer for calculating the overhead power transmission line ice thickness. This solution can realize the unmanned detection of the icing thickness of the transmission line with a simple structure, and has high versatility.

Description

technical field [0001] The invention relates to a transmission line detection device, in particular to an ice coating thickness detection device for an overhead transmission line. Background technique [0002] The normal supply of electricity is related to the normal production of the people and people's lives, and is an important issue of people's livelihood. In recent years, due to the influence of macro-climate and micro-meteorological conditions in my country, ice disaster accidents have occurred frequently, causing huge economic losses. Under certain meteorological conditions, ice crystals accumulate around the wires on the power transmission line. Icing will increase the load on the wires and towers. At the same time, the shape of the circular cross-section of the wires will be changed, and the windward area will be enlarged. Events such as network, torsion, wire disconnection, and pole down, resulting in large-scale power outages. In 2008, a large-scale continuous l...

Problems solved by technology

Under certain meteorological conditions on the transmission line, ice crystals accumulate around the wires. Ice coating will increase the load on the wires and towers, and at the same time change the circular cross-sectional shape of the wires and expand the windward area. network, twisting, disconnection, pole down and other events, resulting in large-scale power outages

In 2008, a large-scale continuous low temperature, rain, snow and freezing weather hit central, southern and southern China, causing accidents such as pole collapse and power interruption, which seriously affected the safe and stable operation of the power communication network

This method only collects ice-covered images, does not further analyze the images, and does not provide important parameters such as ice-covered thickness, and is only used to judge whether there is ice-covered
