Technical Field

The invention relates to the technical field of power transmission operation and maintenance device equipment, in particular to a power transmission channel tree barrier infrared alarm device.

Background

The transmission line is realized by using a transformer to boost the electric energy generated by the generator and then connecting the electric energy to the transmission line through control equipment such as a breaker and the like. The structure form, transmission line divide into overhead transmission line and cable run.

The overhead transmission line consists of a line tower, a lead, an insulator, a line hardware fitting, a stay wire, a tower foundation, a grounding device and the like and is erected on the ground. Power transmission is classified into ac power transmission and dc power transmission according to the nature of the transmitted current. Dc transmission was first successfully achieved in the 80's of the 19 th century. However, the voltage of the dc transmission is difficult to increase continuously under the current technical conditions, so that the transmission capacity and the efficiency are limited. At the end of the 19 th century, direct current transmission was gradually replaced by alternating current transmission. The success of alternating current transmission has already met a new era in the electrified society of the 20 th century.

The protection of the power transmission line is divided into main protection and backup protection.

The main protection generally includes two kinds of longitudinal differential protection and three-stage current protection. Whereas high-frequency protection is now mainly used in ultra-high voltage systems.

The backup protection mainly comprises distance protection, zero sequence protection, direction protection and the like.

The voltage protection and the current protection are not generally used independently at present because reliability and selectivity cannot be met, and the voltage protection and the current protection are generally used in combination. And various protections are equipped with automatic reclosing devices. The protection is divided into interphase and single-phase. If the line is a double-circuit line, the direction needs to be considered.

During setting, the coordination between the various protections needs to be noticed. The capacitance and mutual inductance of the transmission line are also considered, and the branch line exists or not. And a branch transformer, a system operation mode, a grounding mode, a reclosing mode and the like. It is also important that in the power transmission line of 220kV and above system, since the high voltage level fault is mainly a single-phase earth fault, sometimes the fault current is smaller than the load current. And is greatly affected by various line parameters. The impact of various conditions and parameters is especially well taken into account when formulating protection.

The faults caused by external force damage to the power line are more and more, the situation is more complex, and the distribution range is wide. In mountainous areas, the insulator is easily damaged by blasting stone and the lead is easily broken by blasting; crops are burnt below the line, and the line is easy to trip due to flame and dense smoke; large cranes and excavators constructed in the line protection area sometimes break wires and damage towers and the like; some lawbreakers are driven to steal power facilities such as tower materials, stay wires and the like by economic benefits; and fishing, construction against regulations and the like under the power transmission line.

Most power transmission channels are established in the field and can be influenced by factors such as plant growth, an effective observation method is needed for protecting the power transmission channels and preventing line problems caused by various external force reasons, the existing method for observing the power transmission channels mainly adopts manual visual observation or measurement of a distance measuring instrument, a theodolite and a total station, and the defects of high labor cost, inaccurate measurement and large error of the manual visual observation are overcome; though the measurement precision of the theodolite or the total station is high, the equipment is complex, the measurement workload is large, and the theodolite or the total station cannot measure several places in one day.
