Description
Technical field
The present invention relates to a kind of intelligent electric power fittings for transmission line of electricity on-line monitoring.
Background technique
Electric system is the big system being formed by connecting by numerous power generations, transmission of electricity, power transformation, power distribution and power equipment, electricity
The failure of power equipment not only results in power supply system accidental power failure and electric power enterprise economic benefit is caused to reduce, and is possible to make
At the heavy economic losses of user, therefore the reliability of these equipment and operation conditions directly determine the steady of entire electric system
Fixed and safety also determines the economic benefit and power supply quality and reliability of electric power enterprise.
Power equipment is monitored on-line, and monitoring data are analyzed by various advanced calculation methods, with
Just the potential faults of timely discovering device, take preventive measures, and equipment fault diagnosis and the repair based on condition of component of science are realized, to electric power
System reliability of operation, safety are of great significance.With on-line monitoring technique continuous development and maturation, and online prison
Survey technology in recent years in the successful application of China's electric system, repair based on condition of component substitution periodic inspection received by electric system and
Approval, becomes the inexorable trend of overhaul of the equipments.State Grid Corporation of China issued " transformer equipment on-line monitoring system early in 2010
Fire protection technology " and start to popularize facilities and equipments repair based on condition of component in an all-round way, General Promotion device intelligence is horizontal, promotes and applies intelligence and sets
Standby and technology realizes power grid security on-line early warning and device intelligence monitoring.
Currently, on-line monitoring equipment mainly has gas-monitoring, breaker mechanic property monitoring, transformer online monitoring, electricity
The apparatus insulated on-line checking of gas and power transmission line monitor this several big type.In existing market, for the equipment of transmission of electricity on-line monitoring
Function is more single, there is monitoring conductor temperature equipment, windage yaw equipment, shaft tower reclining device, icing detecting devices, transmission line fault
Equipment, electric transmission line isolator filth equipment, visual monitor system etc. are waved in positioning device, power transmission line.But currently without
One equipment can integrate above-mentioned most of function, carry out unified data transmission, provide background server terminal to transmission line of electricity
Operating status carry out 360 degree anatomy, be convenient for trouble saving and early warning failure ahead of time.
Cable fitting, especially conductor spacer are very widely used.The main application of power transmission sequence split conductor conductor spacer
It is the relative motion limited between sub-conductor and the geometry for keeping split conductor under normal operating conditions.But it is existing
Conductor spacer only play the role of split conductor, on the one hand cannot play a protective role to conducting wire, on the other hand do not have take
Carry the function of other equipment or device.Therefore, the on-line checking to transmission line of electricity is realized, it is necessary to electric armour clamp or line
Cable fitting carries out rational modification, is allowed to the on-line checking ability for having certain.
Realize on-line checking, the power supply source of equipment is the problem of facing first.Electromagnetic induction original can be passed through at present
Reason mode obtains energy from power transmission line.It is this technology maturation, reliable and stable, have to the variation of transmission line of electricity electric current stronger suitable
Should be able to power, have short circuit and dash current self-protection, more reliable power supply can be provided for online power transmission line monitoring device.Too
Sun can power it is also contemplated that providing electric energy for detection device, but this mode climate condition is affected, and lacks length
Phase non-maintaining ability, it is solar-powered be not suitable for directly the detection device on transmission line of electricity is powered.For transmission of electricity
Autonomous device near shaft tower, since wide area net mode transmission acquisition data need to be passed through into server, it will consume biggish energy
Amount, provides electric energy using solar powered mode.If nearby having the data access platform of low frequency and low power consumption, transmission tower
Neighbouring equipment only needs very low-power consumption that can complete the data acquired, access platform, the finally external acquisition whole by Platform integration
Data and acquisition data itself are transferred to wide area network.
In Mountainous Areas of Si Sichuan, the hilltop near especially remote village, across complex areas such as great rivers, often without wide
Domain net signal (4G/3G/2G etc.), this brings huge difficulty to the path monitoring of power transmission line, in order to meet this demand, using compared with
It is taken for mature CT and supplies electricity to equipment energy is provided, by wireless self-networking communication modes, collected near the transmission line of electricity in depopulated zone
Sensing data, reaches 360 ° of all standing monitorings, and real-time whole day ensures the stable and reliable operation of the power transmission line in depopulated zone.
