Insulation cover structure with built-in small-capacity power generator and GPS transmitter {A INSULATING COVER STRUCTURE WITH GPS TRANSMISSION DEVICE AND AC POWER GENERATING DEVICE}

The present invention relates to an insulating cover structure in which a small-capacity power generator and a GPS transmitter are built-in, and more particularly, an electromagnetic induction method inside the insulating cover to prevent exposure of live parts such as dead and clamps that combine overhead wires and insulators. Insulation cover structure with built-in small-capacity power generator and GPS transmitter for electric pole and line information communication to communicate various facility information through line current without a separate external power supply. will be.

In general, electricity is a power source and energy source that have a huge impact on industrial sites and daily life environments, and is usually generated in power plants and distributed to factories or users through substations.

At this time, a pole is installed to distribute electricity from the substation to a factory or house, which is the final consumer, and a distribution line is attached to the pole to supply power. The distribution lines installed in the electric pole are flowing relatively high-voltage current, and the distribution lines are connected like a mesh.

In the event that the insulators of the electric poles that fix the distribution lines connected in such a complex structure are deteriorated or the insulation of the distribution lines is destroyed by lightning damage, tree or bird contact, etc., switchgear such as substations or power supply protection devices will operate. Power failure may occur due to power failure or overcurrent may cause safety accidents, industrial facilities may be shut down, and household appliances such as refrigerators and washing machines in the home may stop operating, resulting in enormous damage to property. In the event of a failure (breakdown) in a distribution line, quick recovery should be performed within a short time.

However, at present, the search for the fault point of the distribution line is not carried out automatically, so there is no way to quickly determine whether an overcurrent has flowed due to the breakdown of insulation in a distribution line distributed over a wide area like a net. It takes a lot of time to find it.

Currently, in order to acquire and utilize various operation information on distribution lines, an attempt is made to combine power and communication using IoT sensors, but the basic power supply for various sensors depends on the method and battery through the configuration of low voltage lines. Because of this, there are many restrictions on cost and installation.

In addition, when diagnosing and inspecting distribution lines, the subject of diagnosis (check) is confirmed through visual inspection, and diagnosis (check) contents such as extraction items are stored separately using handwritten records or notebooks, so the error of diagnosis targets And human errors in diagnosis (check) occur due to inconsistencies with diagnosis contents.

As a conventional technique that partially improves such problems, a device for measuring and transmitting fixed information of a distribution line is disclosed in Korean Patent Registration No. 10-1030516 (20110414) "A device for measuring and transmitting fault information of a distribution line".

However, such a conventional device has a problem in that a failure in a control unit, etc. may occur due to an electromagnetic wave generated from an induction coil along with an induction current generation failure while not preventing rainwater from flowing in.
