Description

Aviation obstacle lights for suspended power line}

The present invention relates to a suspended type aviation obstacle light device, and more particularly, to an aviation obstacle light device of a method of receiving power directly from a high voltage line using a current transformer in a type suspended from a high voltage line.

Transmission lines are very dangerous aviation obstacles for low-flying aircraft. Therefore, in order to mark the obstacles as a subordinate obstacle, the aviation obstacle indicator is installed on the overhead branch line installed at the top between the transmission towers in accordance with the Civil Aviation Organization Regulations (ICAO Annex 14-Aerodrom Design Manual) and the domestic aviation law.

However, there is no appropriate display device at night, so a type of display device suspended from a transmission line is being introduced.

There is a CLS (Conductor Lighting System) as a suspended aviation fault display device. The CLS type consists of a guide rod and a leon lamp. However, the CLS type requires a length of 15m for 154kV and about 5m for 345kV in order to secure the proper power.Therefore, there are many parts to hang the induction rod and the light is transmitted in all directions 360 degrees to the vertical direction of the line. Since it is radiated, there is a blind spot in which light is not radiated in the direction of the line on the horizontal plane.

Therefore, a current transformer type is being introduced, but it is not actually used in a special high voltage line. One of the main reasons is that when a low-voltage current transformer is used for extra-high voltage, it is estimated that the structural design and proper electronic circuit design of the peripheral devices are insufficient. Devices or parts suspended from extra-high voltage transmission lines are required to pass tests such as RIV (Radio Interference Voltage), Corona, and mechanical strength (strength in a state of being suspended from high altitude), which are basically applied to the structure. This is because it is not easy.

In addition, the conduction current varies greatly for each transmission line, and even for the same line, the voltage range induced by the current transformer is very wide because the current is different for each time period, so if a large current passes through the current transformer for a long time, the related electronic circuits are exposed to an environment that is prone to damage. Because.

1 shows an installation state of a suspended aerial obstacle light device according to the present invention.

Referring to FIG. 1, a transmission line 20 is installed between the transmission towers 10 at a height of 60 to 100 m above the ground. Aviation obstacle lights 30 are respectively installed at the peak, middle, and lower three locations of the transmission tower 10 and are driven to flicker at night. The transmission line 20 includes an overhead branch line 22 and a high-voltage line 24. In general, an indicator 40 is installed on the overhead branch line 22 and is used as an aviation obstacle indicator during the day. The suspension type aviation obstacle light device 100 according to the present invention is driven to blink at night while being attached to the high-voltage line 24.

FIG. 2 is a schematic diagram of a preferred embodiment of an underslung aviation obstacle light device 100 according to the present invention, and FIG. 3 is a cross-sectional view illustrating an internal structure of an underslung aviation obstacle light device 100 according to the present invention.

Referring to the drawings, the suspension type aviation obstacle light device 100 according to the present invention is accommodated in the inner space of the suspension type case 110, the suspension type case 110, and the track 24 includes the inner cavity part 126. In the rectangular annular core portion 120 detachably coupled to penetrate through, the coil 130 wound around the core portion 120 to be magnetically coupled to the line 24, and the inner cavity 126 portion of the core portion. The shunt core unit 140 disposed between the coil 130 is wound and the line, and a circuit unit that is accommodated in the suspended case 110 and generates an operating voltage by a current induced in the coil 130 ( 150) and a light emitting unit 160 installed at the bottom of the suspended case 110 and driven by an operating voltage generated by the circuit unit 150 to emit display light at 360 degrees with respect to a horizontal plane substantially parallel to the line. ).

In the present invention, the suspension type case 110 is composed of a cover part 112 and a body part 114, and has a rectangular parallelepiped shape as a whole. The suspended case 110 may be made of a metal such as aluminum or a resin material such as plastic, and in the case of a non-conductor such as a resin material, the outer circumferential surface is coated with a conductor. The high-voltage line 24 penetrates between the cover part 112 and the body part 114 so that the body part 114 is coupled to the cover part 112 and is clamped to the high-voltage line 24. The cover part 112 includes a semi-cylindrical upper clamping part 113 extending left and right from a surface in contact with the body part 114. The body portion 114 includes a semi-cylindrical lower clamping portion 115 extending left and right from a surface in contact with the cover portion 112. The cover part 112 and the body part 114 may be fastened by bolts and nuts of the upper and lower clamping parts 113 and 115 extending left and right. The light emitting part 160 is coupled to the bottom of the body part 114. Accordingly, the suspension type case 110 is fixed in a state where the high-voltage line 24 is clamped between the upper and lower clamping portions 113 and 115 to be suspended from the high-voltage line 24. Spacers 116 and 118 are interposed between the upper and lower clamping portions 113 and 115 and the high-voltage line 24. Any one of the left and right spacers 116 and 118 is composed of a conductor and serves to energize the high-voltage line 24 and the outer circumferential surface of the suspended case 110 to be maintained at the same potential. In this case, the spacer on the other side may be an insulator. In addition, the spacers 116 and 118 can adaptively cope with the various thicknesses of the high-voltage line 240. The configuration of the suspension type case 110 maintains the outer circumferential surface of the high-voltage line 24 on the same plane as the high-voltage line 24, while electromagnetic shielding By the role, it is possible to protect the internal circuit from surges such as external corona discharge, etc. In addition, all corners and vertices of the suspended case 110 are rounded. This configuration removes a portion where electric charges are concentrated outside the case. By doing so, it is possible to prevent the occurrence of corona discharge, which is very advantageous in the electromagnetic environment of the extra-high voltage line.

The rectangular annular core portion 120 is composed of a laminate of silicon steel sheets, and is composed of an upper straight portion 122 and a lower horseshoe portion (U-shaped portion) 124. The upper straight portion 122 is fixedly installed in the inner space of the cover portion 112, and the lower horseshoe portion (U-shaped portion) 124 is fixedly installed in the inner space of the body portion 114. Therefore, when the cover part 112 and the body part 114 are clamped to the high-voltage line 24, the vertical ends of the upper straight part 122 and the lower horseshoe part 124 are brought into contact with each other, as shown in FIG. It is to be combined in a square ring shape with an inner cavity 126.

The coil 130 is wound on the horizontal portion of the lower horseshoe portion 124. Accordingly, the coil 130 acts as a secondary winding for the high-voltage line 24 provided as a primary winding, so that the high-voltage line 24 and the coil 130 are magnetically coupled. Therefore, a current is induced in the coil 130 by magnetic coupling.

However, the high voltage line 24 is applied with an extraordinary high voltage of tens to hundreds of kilovolts, such as 22kV, 66kV, 154kV, and 345kV, and accordingly, the applied current varies widely, and even if the line is the same, the current applied varies according to time The induced voltage range is very wide. Therefore, when a large current passes through the current transformer for a long time, the associated electronic circuit may be exposed to an environment that is liable to be damaged.

Accordingly, in the present invention, the shunt core part 140 is configured. The shunt core portion 140 is disposed between the coil 130 and the high-voltage line 24 in the inner cavity portion 126 of the core portion 120. A gap 142 is provided between both ends of the shunt core part 140 and both vertical parts of the lower horseshoe part 124. The voids 142 may exist at both ends, respectively, or may exist only at one side. The void 142 is for increasing the magnetoresistance through the shunt core portion 140. Accordingly, when a current flows through the coil 130 having a small magneto-resistance and self saturation through the iron core is performed, a current flows through the shunt core portion 140 having a large magneto-resistance. Therefore, in the coil 130, it is possible to obtain an appropriate induced current even when the current of the high-voltage line 24 is increased.

The circuit unit 150 includes circuit components mounted on a circuit board. The detailed configuration of the circuit unit 150 will be described later.

The light emitting part 160 is coupled to the bottom of the body part 114 of the suspension type case 110. The light-emitting unit 160 may be composed of a light-emitting unit composed of a high-brightness light-emitting diode and a lens disclosed in Application No. 10-2010-0018633 previously filed by the present applicant. Therefore, detailed description is omitted.

4, the circuit unit 150 includes a transient voltage suppressor (TVS) 151, a noise filter unit 152, an AC/DC converter 153, a bypass unit 154, and a DC/ It includes a DC converter 155, a control unit 156, an illuminance sensor 158, and a light emitting diode array 157.

The transient voltage suppressor (TVS) 151 protects the circuit by blocking extra-high voltage surge voltages and surge voltages caused by corona discharge of high-voltage lines above the limit voltage. The noise filter unit 152 blocks the high frequency switching signal of the converter from being applied to the high voltage line 24. The AC/DC converter 153 converts the induced transmission AC voltage into a DC voltage of several tens of volts. The bypass unit 154 protects insulation breakdown of the current transformer coil due to a through current flowing through the current transformer under no load. The DC/DC converter 155 downs a DC voltage of several tens of volts to a DC voltage of several volts for driving a light emitting diode. The control unit 156 controls blinking driving of the LED array 157. In addition, the control unit 156 is operated by the illuminance sensor 158 to blink and drive the LED array 157 at night and stop blinking and drive the LED array 157 during the day to reduce the operating time of the LED. You can double the number of days. Therefore, in the no-load state, since the current transformer coil 130 is adversely affected, the control unit 156 activates the bypass unit 154. Accordingly, the power bypass unit 154 is deactivated during the activation period of the LED array 157 and is activated during the deactivation period of the LED array 157.

Therefore, by activating the bypass unit 154 at no load, it is possible to protect the insulation damage of the coil 130 of the current transformer, thereby contributing to minimizing the occurrence of a failure for a long time. In other words, if it is installed on the transmission line, it is very difficult to repair the malfunction in a high-altitude and extra-high voltage dangerous environment, and if there is no immediate troubleshooting in the event of a malfunction, the preventive effect of aviation accidents will be halved.

As described above, the present invention has been described with reference to preferred embodiments of the present invention, but those of ordinary skill in the relevant technical field may vary the present invention within the scope not departing from the spirit and scope of the present invention described in the following claims.
