Description

Spacer damper and transmission line temperature monitoring system including the same {SPACER DAMPER AND TEMPERATURE MONITOR SYSTEM OF TRANSMISSION LINE HAVING THE SAME}

The present invention relates to a spacer damper, and in particular, the present invention relates to a spacer damper and a transmission line temperature monitoring system including the same.

Currently, most of the electricity supplied to each customer is provided by transmission lines installed in almost all regions, such as cities and suburbs. Types of transmission lines include underground transmission lines for embedding direct power lines in the ground, and overhead transmission lines for supporting power lines in the air above a predetermined height on the ground by using steel towers (or concrete poles) and insulators.

Underground transmission lines are expensive because they are buried in the ground without additional insulation media and must be manufactured so that they can be insulated from given voltage and commercial frequency voltage by the power line itself.

As the overhead transmission line increases with increasing transmission capacity, instead of the single-conductor method in which the conductor configuration is a single conductor, the multi-conductor method is used. At this time, the conductors constituting the polyconductor are referred to as small conductors, and in general, 2 N small conductors (in which N is a natural number) in the order of a single conductor, a corridor, a two conductor, and a six conductor constitute one line. In order to make constant the conductor spacing of the polyconductor transmission line, an apparatus is required, which is called a spacer, and a device having a vibration damper for controlling vibration of the small conductor in the spacer is called a spacer damper.

Spacer damper is an essential device installed at regular intervals in transmission lines that use the multi-conductor transmission line method to maintain the spacing between small conductors and to prevent torsion or slit jumping.

Most of Korea's transmission lines are located in mountainous terrain, making them vulnerable to damage from wildfires. Most power transmission equipment, such as high voltage lines, are installed in mountainous areas without human input for safety. Because of this, it is difficult to quickly extinguish when a fire breaks out, so the heat and flame damage to the power transmission system is very great.

Currently, transmission lines are developing in a complex form due to the rapid increase in electric power demand, which leads to the difficulty of controlling the entire power system in the event of a sudden accident with limited operation personnel and conventional systems.

1 is a view showing a transmission line temperature monitoring system according to an embodiment of the present invention.

Referring to FIG. 1, the transmission line temperature monitoring system includes a spacer damper 100 and a data management device 300.

The spacer damper 100 includes a clamp 130, a main body 110, a current inducing unit 145 (shown in FIGS. 2 and 3), a temperature sensor 180, and a data processing device 200. Here, the six-conductor spacer damper 100 has been described as an example, but the present invention is not limited thereto. It will be obvious to those skilled in the art that the technical idea of the present invention can be applied to the two-conductor, four-conductor spacer damper 100. . In addition, the present invention can be equally applied to other methods as well as 2, 4, 6 conductor method.

The spacer dampers 100 are formed by six clamps 130 spaced apart at regular intervals. The number of clamps 130 may vary depending on the number of small conductors 50 of the power transmission line. For example, in the case of two conductors, the number of clamps 130 may be two, and in the case of four conductors, the number of clamps 130 may be four.

The clamp 130 surrounds and fixes the outer portion of the small conductor 50, and transmits the vibration generated from the small conductor 50 to the main body 110 through the clamp connection 135.

The clamp 130 is connected to the main body 110 through the clamp connection 135. The main body 110 has a hollow portion 120 having a polygonal shape in the center. The clamp 130 is connected to the clamp connection part 135 by being spaced apart at a predetermined interval about the hollow part 120.

The main body 110 may be formed in a different shape according to the 2, 4, 6 conductor type. For example, when the main body 110 is a six-conductor type transmission line, as shown in FIG. 1, the main body 110 may maintain the six small conductors 50 at regular intervals from each other. In addition, the main body 110 may be formed in the form of a square in the case of a four-conductor transmission line to maintain four small conductors 50 at regular intervals.

The current inducing unit 145 is formed inside the clamp 130, and induces a current from the small conductor 50 to generate an induced current signal. The current induction part 145 may be formed of a Rogowski coil or a plurality of conductors. In this case, the Rogowski coil is used to detect the current flowing in the small conductor 50, and may be manufactured by penetrating one end of the coil uniformly wound into the coil to attenuate the magnetic flux in the vertical direction on the coil cross section. . Rogowski coils can measure large currents, and they do not contain magnetic materials, so they have excellent linearity and have no internal iron cores, so they do not suffer overcurrent damage due to iron core saturation. The current inducing unit 145 may generate an induced current signal according to a change in current of the Rogowski coil.

The current inducing unit 145 transmits the generated induced current signal to the data processing device 200 through the first supply line 170.

The clamp 130 and the current induction part 145 will be described in more detail with reference to FIGS. 2 and 3.

The temperature sensor 180 is formed at the hollow portion 120 of the main body 110 together with the data processing device 200. For example, the temperature sensor 180 may be formed to correspond to the number of small conductors 50 on the outer side of the data processing apparatus 200 formed at the center of the hollow part 120.

The temperature sensor 180 receives and drives an induced current signal from the current inducing unit 145. The temperature sensor 180 generates temperature information by measuring the temperature of the small conductor 50 and the ambient temperature. At this time, the temperature sensor 180 is formed of at least one of the contact temperature sensor 180 in contact with the small conductor 50 of the power transmission line and the non-contact temperature sensor 180 in non-contact with the small conductor 50 of the power transmission line. Can be. For example, the contact temperature sensor 180 may be formed of a sensor capable of contacting and sensing a temperature such as a (platinum) resistance temperature sensor, a thermistor temperature sensor, a thermocouple temperature sensor, and a bimetal temperature sensor. The non-contact temperature sensor 180 may be formed as a sensor capable of detecting a temperature by contacting such as a radiation temperature sensor.

The data processing apparatus 200 wirelessly connects to the data management apparatus 300. The data processing apparatus 200 receives and drives an induced current signal from the current inducing unit 145. The data processing device 200 receives temperature information from the temperature sensor 180. The data processing device 200 converts temperature information, which is an analog signal, to temperature processing information, which is a digital signal, for wireless transmission to the data management device 300. The data processing apparatus 200 transmits the converted temperature processing information to the data management apparatus 300 by wireless communication. The data processing apparatus 200 will be described in more detail with reference to FIG. 4.

The data management apparatus 300 wirelessly connects with the data processing apparatus 200 of the spacer damper 100 and receives temperature processing information from the data processing apparatus 200 of the spacer damper 100 by wireless communication. The data management device 300 converts the temperature processing information into temperature information and location information. The data management device 300 compares the temperature information with the reference information to determine whether the small conductor 50 is abnormal. If the temperature information is greater than the reference information, the data management device 300 determines that an abnormality has occurred in the small conductor 50, and transmits the temperature information and the location information to the track failure history management device. In this case, the data management device 300 may be located in a moving vehicle or may be mounted in a mobile terminal moved by a user. Here, the type of mobile terminal is irrelevant as long as it is a terminal capable of transmitting and receiving data wirelessly. For example, the mobile terminal may be one of a mobile communication terminal capable of a voice call, a personal digital assistant (PDA), a portable computer such as a laptop and a netbook.

The data management apparatus 300 will be described in more detail with reference to FIG. 5.

The clamp of the space damper according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3.

2 and 3, the insertion groove 143 is formed on the inner surface of the clamp 130. The current induction part 145 is inserted into the insertion groove 143. In this case, the current inducing unit 145 may be formed of a Rogowski coil. The current inducing unit 145 is connected to the first supply line 170 and the second supply line 173 through the first coil output terminal 147 and the second coil output terminal 149. That is, the current induction unit 145 transmits the induced current signal to the data processing apparatus 200 through the first coil output terminal 147 and the first supply line 170, and the second coil output terminal 149 and the second supply line ( 173 is transmitted to the temperature sensor 180.

The clamp 130 is open at one side such that the small conductor 50 is inserted. That is, the cover 130 of the clamp 130 is opened from the fixing portion 133 by the hinge 137. When the small conductor 50 is inserted into the clamp 130, the fixing screw 159 is inserted into the first through hole 155 formed in the fixing part 133 and the second through hole 157 formed in the cover part 135. The fixing screw 159 is fixed with the fixing bolt 161 to fasten the fixing part 133 and the cover part 135. In addition, the clamp 130 may fasten the fastening means 151 to the fixing part 133 and the fastening groove 153 to the cover part 135 to doublely fasten the fixing part 133 and the cover part 135. have.

Here, the hinge-type clamp is described as an example, but the present invention is not limited thereto. The clamp 130 may surround the outer conductor of the small conductor 50 and fix the small conductor 50. For example, the clamp 130 may be a detachable clamp.

A data processing apparatus according to an embodiment of the present invention will be described with reference to FIG. 4.

The surge protector 210 is positioned between the current inducing unit 145 and the rectifier 220. The surge protection unit 210 prevents the surge voltage from flowing along with the induced current signal from the current induction unit 145. The surge protector 210 protects the components of the data processing apparatus 200 from the surge voltage. In this case, the surge voltage may be generated due to voltage input or interruption in the transmission line, or may be generated due to an abnormal phenomenon in the transmission line.

The rectifier 220 supplies an induced current signal through the surge protector 210. In this case, the induced current signal flows into the data processing apparatus 200 from the current inducing unit 145 through the first supply line 170. The rectifier 220 rectifies the induced current signal, which is an AC power source, into a DC power source.

The accumulator 230 receives DC power from the rectifier 220. The accumulation unit 230 accumulates the DC power, and supplies the accumulated DC power to the communication unit 240, the GPS module 250, the analog-to-digital converter 260, and the transmitter 270. At this time, the communication unit 240, the GPS module 250, the analog-to-digital conversion unit 260, and the transmission unit 270 are driven using the DC power supplied from the storage unit 230.

The communicator 240 is connected to the temperature sensor 180. The communicator 240 receives temperature information from the temperature sensor 180 through a data signal line. The communicator 240 provides the received temperature information to the analog-digital converter 260.

The GPS module 250 receives GPS information about the position of the spacer damper 100 from the satellite. The GPS module 250 analyzes GPS information to generate location information of the spacer damper 100. The GPS module 250 provides the generated position information to the analog-digital converter 260.

The analog-digital converter 260 converts temperature information and position information into temperature processing information. That is, the analog-to-digital converter 260 transmits the temperature information and the position information, which are analog signals, to the data management apparatus 300 wirelessly through the transmitter 270, to the temperature management information, which is a digital signal. Convert to

The transmitter 270 wirelessly connects to the data management apparatus 300. The transmitter 270 transmits the temperature processing information to the data management apparatus 300 through wireless communication.

In other words, the digital analog converter 320 converts temperature processing information, which is a digital signal, into temperature information and position information, which is an analog signal, in order to process data in the data management apparatus 300.

The comparison unit 330 compares the temperature information with the reference information to determine whether the small conductor 50 is abnormal. Specifically, the comparison unit 330 determines that the abnormality of the small conductor 50 occurs when the temperature information is higher than the reference information, and when the temperature information is lower than the reference information, the abnormality does not occur in the small conductor 50. Can be judged. In this case, the reference information is information which is a reference for determining that the temperature of the small conductor 50 is abnormal. The reference information may be set by receiving input from a user or by using a preset algorithm (for example, a program and a probability model).

Meanwhile, the comparison unit 330 generates difference information by comparing the temperature information with the reference information. The comparison unit 330 provides the generated difference information to the output control unit 350.

The generation unit 340 generates result information including temperature information and location information. That is, the generation unit 340 generates the result information by matching the location information with the temperature information if the result determined by the comparison unit 330 is greater than the reference information.

The output controller 350 controls the transmitter 360 to transmit the result information to the external device according to the difference information. In this case, the external device may be at least one of a public office, a user terminal, and a track failure history management device.

The line failure history management device may be a device for managing a failure history of a transmission line in a company managing a transmission line.

For example, if the difference information is large, the output controller 350 may control the transmitter 360 to transmit the result information to all the government office, the user terminal, and the track failure history management information. In addition, if the difference information is small, the output control unit 350 may control the transmitter 360 to transmit the result information to the track failure history management information. The external device transmitting the result information according to the difference information may be set by the user.
