Description

System for watching fault section of power distribution line

The present invention relates to a failure section monitoring system of an urban overhead distribution line in the field of distribution technology, and more particularly, it is installed on the distribution line to display whether the distribution line is faulty or not, while confirming the distribution line in which the failure has occurred It is related to a fault section monitoring system for urban overhead distribution lines that exposes flags so that complaints can be made quickly and accurately so that complaints can be made quickly and accurately.

In general, a distribution line consists of a pole installed on the ground at a certain interval, a wire rod installed on the pole, a distribution line installed between the pole and the pole and supported in an insulated state by an insulator, and a distribution line installed on both sides of the pole It consists of a jump line connecting the

Because these distribution lines are exposed to wind and rain and sunlight, breakdowns occur frequently.

In particular, it is difficult to detect a faulty section of a distribution line when it is covered by obstacles such as a street tree or a building or when a failure occurs due to a minute scratch, and it takes a lot of time.

As a prior art that has improved these problems, Republic of Korea Patent Registration No. 10-1482669 (announced on January 14, 2015) "distribution line failure display device" (hereinafter 'prior art 1') is installed on an overhead distribution line and includes a control unit; a sensing unit configured to sense at least one of current, voltage, and temperature on the distribution line and output sensing data; A distribution line in which a failure has occurred, including a failure determination unit that determines whether a failure occurs on the distribution line using the detection data, and a lamp unit that is turned on under the control of the controller when it is determined that a failure has occurred on the distribution line Disclosed is a technology that allows the section to be easily recognized from the outside, and the level of danger can be recognized from the outside by making a different display depending on whether there is a failure.

However, the prior art 1 has a problem in that it is difficult to safely protect the lamp unit from wind and rain since the lamp indicating a failure is exposed.

In addition, as a prior art that improved these problems, Republic of Korea Patent Registration No. 10-1765065 (Aug. 8, 2017. Announcement) "Fault point detection system of distribution lines" (hereinafter 'Prior Art 2') is a transparent protective wall for the lamp part. Disclosed is a technology that protects the lamp unit from wind and rain by overlaying it, and blocks sunlight by a plurality of diffuser plates that are foldably installed on the upper part and a corrugated plate connected between the diffuser plates so that the failure indication of the lamp unit can be effectively transmitted. have.

However, in the prior art 2, since the lower end of the protective wall covering the lamp unit is open, wind and rain enter the lamp unit and damage the light bulb or LED module constituting the lamp unit.

In addition, although the extension plate of the protection unit is elastically supported by a plurality of connecting lines and springs, there is a problem in that the connecting lines and the springs are installed on the upper surface of the extension plate and are exposed to wind and rain at all times, so that they are easily corroded and easily lose their functions.

In addition, as a prior art that solves this problem, Republic of Korea Patent No. 10-1932960 (Notice on Dec. 27, 2018) "Automatic fault monitoring device for distribution lines" (hereinafter referred to as 'prior art 3') is installed on the distribution line The faulty distribution line is displayed externally, and the faulty distribution line can be easily identified, and the lamp unit can be safely protected from wind and rain by providing a protection device, and the temperature of the lamp unit is set. When the temperature is higher than the temperature, it opens between the upper transparent protection cylinder and the lower transparent protection cylinder and exposes the lamp to the atmosphere through the opening to lower the temperature of the lamp, thereby preventing shortening of the life of the lamp due to heat generation. Disclosed is a technology that can improve visibility when the lamp is turned on and has a complaint reporting means so that complaints can quickly and accurately report a breakdown.

However, in the prior art 3, when the temperature of the lamp unit is higher than the set temperature, the lower transparent protection cylinder is lowered to open between the upper transparent protection cylinder and the lower transparent protection cylinder, and the lamp unit is exposed to the atmosphere through the opening to lower the temperature of the lamp unit. However, in this case, rainwater enters the inside of the upper and lower transparent protection cylinders through the opening between the upper and lower transparent protection cylinders, and the lamp part is exposed to the rainwater, and there is a problem that the lamp part easily breaks down.

In addition, a lifting mechanism for opening and closing between the upper and lower transparent protection cylinders is mounted on the lower surface of the upper plate of the housing and the motor shaft protrudes downward, the lifting screw coupled to the motor shaft, and the upper surface of the upward concave part of the lower transparent protection cylinder The lower end is fixed in the center and includes an elevating screw pipe having a female screw portion engaged with the elevating screw, and the lamp unit includes a fixed tube fixed to the lower surface of the disc part of the upper transparent protective cylinder, a plurality of metal substrates coupled to the outer circumferential surface of the fixed tube, and metal It is composed of a plurality of LED chips mounted on the surface of the substrate, and since the elevating screw of the elevating mechanism penetrates through the fixing tube of the ramp, the heat generated from the ramp is transferred to the elevating motor through the metal substrate, the fixed tube and the elevating screw. There is a problem in that the life of the elevating motor is greatly shortened due to the continuous heating.

In addition, four guide bosses protrude on the inner circumferential surface of the lower transparent protection cylinder, and four guide rods are inserted into the guide boss. There is this.

Also, on metal or synthetic resin boards where the pole number tag is common, warning text, upper, hardness indication, detailed location indication, line name indication, track order indication, installation year and month indication, pole height indication, power company logo, As a QR code printed, there is a problem that visibility is greatly reduced at night.
