[0028] Reference Figure 1-5 The figure shows a preferred embodiment of the present invention.

[0029] The integrated device for reducing loss and increasing efficiency of high-voltage overhead transmission lines under complex weather conditions includes an abnormality elimination unit 200, which includes a bearing 203 sleeved on the outer periphery of a transmission line 300, a rubber ring sleeved on the outer periphery of the bearing 203, a brake copper ring sleeved on the outer periphery of the rubber ring, and a metal outer shell ring 202 sleeved on the outer rear of the brake copper ring. The transmission line 300 here is a high-voltage overhead transmission line 300.

[0030] A pulse coil is provided in the outer shell ring 202, and the pulse coil is electrically connected to an adjustable energy storage capacitor. When the energy storage capacitor discharges the pulse coil, the pulse coil generates a pulse current, and an induced eddy current is generated on the brake copper ring of the pulse current. The induced eddy current generates a pulse force in the pulse magnetic field generated by the pulse current. Under the action of the pulse force, stress is generated and propagated near the foreign matter removal unit 200. When the stress exceeds the bonding strength of the foreign matter on the transmission line 300, the foreign matter on the transmission line 300 is separated from the transmission line 300, that is, the effect of removing the foreign matter is achieved.

[0031] The above-mentioned integrated device for reducing losses and increasing efficiency of high-voltage overhead transmission lines under complex weather conditions, during the operation of the high-voltage overhead transmission line 300, discharges the pulse coil through the energy storage capacitor to generate a pulse force on the brake copper ring. The pulse force propagates along the transmission line 300, which effectively solves the risks of corona loss, icing, water accumulation, and dust accumulation that may occur on the transmission line 300. It can easily remove foreign matter on the transmission line 300 to achieve efficient foreign matter removal and zero-manpower cleaning of the transmission line 300, and solves the problems of consuming a lot of manpower and material resources in the process of manually shaving ice, water attached to the line, and attached dust.

[0032] In this embodiment, the transmission line 300 has a conductor 301, the outer periphery of the conductor 301 is coated with an insulating layer 303, the outer periphery of the insulating layer 303 is coated with a conductive layer 302, and a sampling resistor 304 is connected between the conductor 301 and the conductive layer 302 to form a sampling circuit. The sampling circuit is electrically connected to the corona loss film sensor, and the corona loss film sensor is electrically connected to the energy storage capacitor.

[0033] The corona loss film sensor measures the corona loss value of the conductor 301, and the energy storage capacitor adjusts the discharge size of the pulse coil according to the corona loss value to adjust the pulse force.

[0034] By arranging the sampling resistor 304, the leakage current of the corona of the transmission line 300 can be separated, and the corona loss value can be calculated, and the corona loss film sensor is interconnected with the energy storage capacitor to finally achieve the regulation of the generated pulse force. By roughly calculating the capacitive reactance between the wire 301 and the conductive layer 302, the sampling resistor 304 is selected as a precision non-inductive resistor with a resistance value of 200Ω.

[0035] There are many factors involved in the calculation of corona loss, which are related to the geographical environment, climatic conditions, conductor 301 structure and actual operation conditions. The main factors affecting the corona discharge of transmission line 300 include: the corona field strength on the conductor surface, the surface condition of conductor 301, the particles near conductor 301, the water droplets on conductor 301, the air temperature, the humidity, etc.

[0036] According to the meteorological conditions in most parts of my country, weather conditions can be divided into the following four categories:

[0037] 1) Rainy days - including drizzle and various rainfall intensities;

[0038] 2) Snowy days - including rime, sleet, wet snow and dry snow;

[0039] 3) Fog days - including various foggy days, frosty days, haze days, sandstorm days and snowy days;

[0040] 4) Others - In addition to the above three types of weather, it includes sunny, cloudy, overcast and partly cloudy weather.

[0041] The corona loss value measurement system includes hardware and software. The hardware part includes programmable amplifier module, analog-to-digital conversion module, communication module, GPS timing module, storage and control module and power supply. The software part first commands the acquisition card to filter and analyze the voltage signal collected by the acquisition card at each point, and then calculates the corona loss value, stores the data and transmits it to the microcontroller so as to control the energy storage capacitor and adjust the generated pulse force.

[0042] In this embodiment, the single chip microcomputer is used as the main controller, the solar cell is used as the power source, the sensor is used as the input, and the external adjustable energy storage capacitor is used as the output.

[0043] The STM32F103C8T6 microcontroller is a 32-bit microcontroller based on the ARM Cortex-M3 core, acting as the host. The I port of the microcontroller pre-processes the collected electrical signals. After the analog signals input to the acquisition board are quantized, they are transmitted to the microcontroller control center in digital form to adjust the adjustable capacitors using PWM waves.

[0044] In the software system, the corona loss sensor is firstly set up to realize the synchronous acquisition of voltage signals. Then, the acquired voltage signals are filtered and analyzed for consistency, and then the corona loss value is calculated.

[0045] Finally, the value is compared with the corona loss value in the program to determine the size of the discharge of the energy storage capacitor to the pulse coil, and the PWM wave is used to adjust the size of the energy storage capacitor to control the pulse force.

[0046] The basic circuit structure of electromagnetic pulse removal is mainly composed of pulse power supply, pulse energy storage capacitor, charge and discharge switch and pulse coil. The electromagnetic pulse removal process is mainly divided into three steps:

[0047] 1) The charging high-voltage relay is turned on, and the energy storage capacitor bank is charged by the pulse power supply;

[0048] 2) The charging high-voltage relay is turned off, the power supply is isolated from the discharge circuit, and the trigger signal controls the discharge switch to turn on. At this time, the energy storage capacitor bank discharges the pulse coil, generating a large pulse current and a transient magnetic field;

[0049] 3) Induced eddy currents are generated inside the foreign body target. The time for the eddy currents to interact with the coil magnetic field is in the order of microseconds, but they can generate electromagnetic forces ranging from tens to thousands of Newtons. The electromagnetic force causes the metal to move at high acceleration within the range of elastic deformation. The target object generates stress and forms strain under the action of high acceleration. When the bonding strength between the foreign body target and the wire is less than the pulse stress, the foreign body begins to decompose and fall off.

[0050] The microcontroller adjusts the duty cycle of the PWM signal according to the change of the corona loss value, thereby controlling the output voltage of the power supply, and applying the voltage to the gate of the MOS variable capacitor. By adjusting the voltage value, the charge storage amount of the capacitor is controlled, thereby changing the capacitance value.

[0051] As the gate positive bias voltage increases, the energy band diagram of the MOS capacitor crosses the threshold inversion point. Ideally, a differential change dV of the MOS voltage will lead to a differential change in the inversion layer charge density. If the inversion layer charge can keep up with the change in the capacitor voltage when the width of the space charge region remains unchanged, the total capacitance is the gate oxide capacitance.

[0052] With V GS The increase of interface hole density decreases, considering V G = 0, at this time, a depletion region will also be formed between the n-type semiconductor and the substrate at both ends of the source and drain, so the accumulation region and V G = 0 bias voltage, there will be a downward trend in the total capacitance C. In order to make the capacitance value change monotonically with the control voltage, the NMOS is installed in the N-Well, so that the device will not have an inversion region.

[0053] Corona is a complex physical phenomenon. Its magnitude is related to the electric field strength on the surface of the conductor 301, air density and meteorological conditions. The field strength on the surface of the conductor 301 is related to the splitting mode, cross-sectional area, phase-to-phase distance and operating voltage of the conductor 301. The corona loss value per unit length of the 500kV to 1000kV transmission line 300 is calculated as follows:

[0060] The calculation formula of the surface field strength of the intermediate phase is as follows:

[0061]

[0062] The calculation formula of the surface field strength of the edge phase is as follows:

[0063]

[0064] In the above formula:

[0065] λ——coefficient for calculating the maximum electric field strength on the surface of the split conductor 301;

[0066] Cav——average capacitance, in pF / m;

[0067] n——number of splits;

[0068] r——radius of sub-conductor 301, in cm;

[0069] U——actual operating voltage, in kV.

[0070] Since D1 is only about 6% larger than D2, it can be approximately considered that D2=D1=D.

[0071] If the operating voltage of the transmission line 300 is replaced by the average voltage at its head and end, the weighted average value of the corona loss in one year is calculated as follows:

[0072]

[0074]

[0075] V i 、V j ——respectively the operating voltage at the beginning and end of the line, in kV;

[0076] T f , T s , T r ——They are respectively the duration of other weather conditions, snowy days, and rainy days in a year, in hours.

[0077] For an N-node system, the power equation for node i is calculated as follows:

[0078]

[0080] l y ——The length of the transmission line 300i-j.
