Description

{DISTRIBUTION LINE INSULATOR}

More particularly, the present invention relates to a first electric pole machining facility to an n-th (2 or more natural) electric pole machining facility constituting a connection point of a power line on a high-voltage or extra-high pressure electric power distribution line, , And a faulty insulator detection device for detecting faulty insulators by using an image of a voltage measurement of insulators and an image of the surrounding environment among the components of the first to (n + 2) To a power line supported type insulator.

Generally, the insulator is installed on the upper part of the power distribution line, and supports and supports the wires. At the same time, the insulator is deteriorated due to aging and breakage after a certain period of time, As a result, it is impossible to perform insulation function, which is an essential function of the insulator. Therefore, in order to solve this problem, the insulator of the insulator is periodically checked to detect the insulator.

However, until now, in order to detect the insulator, the operator inspects and analyzes the insulation condition of the insulator by separately describing the inspecting items (voltage value, inspection date, defectiveness, etc.) on a separate sheet after measuring the insulator voltage. It is not easy for the operator to visually read the voltage readings on the potentiometer accurately, considering that the operator must measure the voltage of the insulator at a distance of 1M or more for safety reasons. In addition, It is impossible to accurately describe the voltage value due to misjudgment in the process described in Patent Document 1. As a result, the defective insulator can not be accurately detected.

The communication unit 221 can acquire the current measurement information of the insulator installed on the processed transmission / distribution line through an external leakage current measuring device and a network. In this case, the communication unit 221 may be a Zigbee, WiFi, CDMA, 3G, 4G, LTE, LTE-A, and Wireless Broadband Internet.

Here, the leakage current measuring device can easily measure the leakage current of the insulator installed on the processing and transmission line on which a high voltage is flowing, which is difficult to measure by human being using a unmanned air vehicle such as a drone, And transmits it to the current analyzer 220a in real time.

The operation unit 222 allows various commands to be input through predetermined input means (such as a keyboard, a touch screen, and the like).

The leakage current analyzing unit 224 analyzes the current measurement information of the insulator obtained to determine leakage current depending on the type of insulator.

For example, when the type of the insulator is the support insulator, the leakage current analyzer 224 compares the reference current value with the measured value of the secondary current of the support insulator, and analyzes the presence or the leakage current amount of the leakage current.

In this case, the current difference is calculated by subtracting the current measurement value of the primary side and the secondary side of the support insulator. The calculated current difference is compared with the reference current difference to analyze the leakage current presence or leakage current amount.

Basically, it is judged that leakage current occurs when the current measurement value is larger than the reference current value or the calculated current difference is larger than the reference current difference, and the leakage current amount is confirmed by the current measurement value or the calculated current difference value.

The leakage current analyzer 224 compares the reference current value with the secondary current measurement value of the secondary side of the suspending insulator or the lightning arrester and analyzes the leakage current presence or leakage current amount when the type of the insulator is the suspend insulator.

In this case, basically, if the current measurement value is larger than the reference current value, it is determined that a leakage current has occurred, and the leakage current amount is confirmed by the magnitude of the current measurement value.

That is, the insulator replacement determination unit 225 compares the analyzed leakage current presence / absence value and the leakage current amount with each other to determine whether the insulator is replaced or not by comparing the reference leakage current amount previously set for insulator replacement.

In this case, when the detected leakage current amount is larger than the reference leakage current amount, it is determined that the insulator replacement is performed. If the leakage current of the insulator is large, a ground fault occurs, or when the lightning or surge penetrates, And is burned to cause a bigger accident.

The analysis result display unit 226 displays result information analyzed by the leakage current analysis unit 224 and the insulator replacement determination unit 225 on the screen so that the administrator can easily recognize the leakage current state of the insulator installed in the power equipment It will.

In this case, when the leakage current of the insulator becomes the insulator replacement state, it is preferable to generate an alarm so that the manager recognizes it.

Therefore, the user recognizes the leakage current state of the insulator through the analysis result display unit 226, and if the leakage current of the insulator is generated and the leakage current is recognized as the insulator replacement state, the insulator is quickly replaced to prevent a ground fault, And prevent further accidents due to deterioration and burnout of the vehicle.

The text message processing unit 227 includes a text message generation unit 227a and a text message transmission unit 227b.

The text message generating unit 227a determines that a leakage current of the insulator has been generated through the leakage current analyzer 224 and if the insulator replacement is determined through the insulator replacement determination unit 225, The alarm data is generated in a character form.

Here, the alarm data may include insulator information (for example, insulator position information, insulator type information, etc.) where leakage current occurs and leakage current information.

The text message transmission unit 227b transmits the alert data generated through the text message generation unit 227a to an external administrator terminal in response to a command from the control unit 228. [

The control unit 228 includes a communication unit 221, an operation unit 222, a storage unit 223, a leakage current analysis unit 224, an insulator replacement determination unit 225, an analysis result display unit 226, .

By using the unmanned aerial vehicle, And provides a technical advantage to prevent an electric shock accident caused by measurement in advance.

In addition, according to the present invention, when a leakage current of an insulator is generated, it is generated as a text message and transmitted to a portable terminal of a manager, thereby enabling a manager to recognize the leakage current of the insulator regardless of the position of the manager.
