Embodiment Construction

[0012] see Figure 1 to Figure 3 , according to a kind of transmission line icing and melting test method of the present invention, in the test, use the tension sensor to measure the gravity of the sample in real time, and the sensor has the characteristics of large load and small inductance. When a high voltage is applied, the value of the applied voltage and the height h in the test can be matched accordingly. The height h is the height h between the wire and the ground wire, or the height h between the insulator and the ground wire, so that the wire or insulator is in contact with the ground wire. The electric field of the ground wire is in the same electric field environment as the line operation. During the test, the sensors can also measure parameters such as temperature, wind speed and precipitation near the surface of the sample in real time. All sensors can be used normally under low temperature and high humidity conditions. When applying current to the wire, a larg...

Abstract

The invention relates to a test method for icing and deicing of a transmission line, which comprises the following steps: measuring the gravity of a sample in real time by using a tension sensor; whenapplying a high voltage, applying a voltage to a test and correspondingly matching the value of a height h from a wire or an insulator to a ground wire so as to make the electric fields of the wire or the insulator and the ground wire in the electric field environment for operating a line; measuring the temperature, a wind speed and a precipitation parameter close to the surface of the sample inreal time by a sensor; and transmitting sensor data and test data of a climatic chamber to a computer to record and process the data uniformly in real time so as to realize an automatic measurement. The test system of the invention comprises a hoisting device, a suspension device, a supporting device and a high voltage bushing, wherein a plurality of sensors are connected to a data acquiring device and the computer through lines. The test method for the icing and the deicing of the transmission line and the test system thereof can realize the determination of different icing types and the simulation of the increase rule of the icing of a corresponding type according to characteristics of the icing, the icing density and the icing weight.

Description

technical field [0001] The invention relates to a power transmission line, in particular to a method for researching and testing the mechanism of ice coating and ice melting of the power transmission line and a test system thereof. Background technique [0002] The research on icing of transmission lines has been going on for more than half a century in the world. The international standard IEC60826-2003 stipulates the artificial test device for icing research, but there is no test method and its methods specially used for this research. dedicated system. Contents of the invention [0003] The task of the present invention is to provide a transmission line icing and melting test method and its test system, which solves the problem that there is no test method and special system specially used for this research. [0004] Technical solution of the present invention is as follows: [0005] An ice-covered and ice-melting test method for a power transmission line uses a tensi...
