Safe and intelligent electric power tower

Abstract

The invention discloses a safe and intelligent electric power tower. The safe and intelligent electric power tower comprises a tower body, a grounding device, an intelligent detecting bird repelling device and a lightning arrester, wherein the tower body comprises four tower columns; each tower column sequentially comprises a tower column foundation layer, a reinforcing layer, a honeycomb sandwich layer, a tower column outer layer and a corrosion resistant layer from inside to outside; the intelligent detecting bird repelling device is arranged on the top of the tower body; three cross arms are arranged on the upper portion of the tower body; the lightning arrester, a red copper connecting plate and an insulator are sequentially connected between each two adjacent cross arms from top to bottom; the bottom cross arm is provided with a signal processing module, a solar cell panel and a cathode protection and control device; the cathode protection and control device, an auxiliary anode and a reference electrode form an impressed current protecting system; and the solar cell panel supplies power for the signal processing module and the impressed current protecting system. The safe and intelligent electric power tower is high in corrosion resistance, long in service life and low in maintenance cost; the purpose of repelling birds and monitoring a surrounding environment can be achieved; the electric power tower can be monitored and managed remotely; and intelligent degree is high.

Description

technical field [0001] The invention relates to electric equipment, in particular to a safe and intelligent electric power tower. Background technique [0002] Since the grounding device of the transmission line tower is buried in the soil for a long time, the soil will cause galvanic corrosion to the grounding device. In addition, in the HVDC transmission system, when the working current or unbalanced current of the DC system flows through the ground through the DC grounding electrode, it will also It will also have a corrosion effect on the grounding device of the transmission line tower around the grounding pole; after a few years of use of the general buried grounding device, there will be multiple rusts, local rust breaks, and even multiple rust breaks, which will easily cause poor grounding of the tower , which seriously affects the safe and stable operation of the power system; the transmission tower is the support of the long-distance transmission line, which has the...

[0002] Since the grounding device of the transmission line tower is buried in the soil for a long time, the soil will cause galvanic corrosion to the grounding device. In addition, in the HVDC transmission system, when the working current or unbalanced current of the DC system flows through the ground through the DC grounding electrode, it will also It will also have a corrosion effect on the grounding device of the transmission line tower around the grounding pole; after a few years of use of the general buried grounding device, there will be multiple rusts, local rust breaks, and even multiple rust breaks, which will easily cause poor grounding of the tower , which seriously affects the safe and stable operation of the power system; the transmission tower is the support of the long-distance transmission line, which has the characteristics of high flexibility, large span of ground wire, and strong nonlinearity. Most of the body is made of iron materials. Under the harsh weather conditions in the field, it suffers from conventional corrosion and additional corrosion and damage caused by harsh weather and environment, which adds a large cost to the operation of the power system; the arrester is a transmission line One of the necessary supporting facilities for the cable. In the prior art, the counters of the line arrester must be placed on a very high pole tower. The placement position is too high, which is not conducive to inspection and maintenance; The excrement of birds and the branches of nests are likely to cause accidents such as line overlap and short circuit. In order to prevent birds from building nests on pole towers, measures such as discharge, light emission, and sound are generally used, but none of them can achieve the desired effect; the operation and management of China's transmission network has been constantly Following the traditional management model based on the division of labor between functional departments and relying heavily on manual inspections, there is a lack of effective visual monitoring management and commanding technical means for the integrity of the transmission network, resulting in inconsistent management processes and goals, which to a certain extent lead to the existence of power grid equipment. Serious and critical defects; based on the above problems, it is necessary to carry out technical improvement and improvement on the existing transmission towers
