For example, in the following, since the operation of the fault point expression device installed in a substation, an auxiliary substation, a division station, etc. is already well known to those skilled in the art, a detailed description thereof will be omitted.

It is an illustration of a power supply system diagram for testing, and FIG. 3 illustrates a case of using two transformers as the low voltage supply transformers 100 in FIG. 1 . 4 is an exemplary view of the operation panel unit 600 of FIG. 1 .

1 and 2 show only one low-voltage supply transformer 100 and a configuration positioned at the rear end thereof for convenience of explanation, but in FIG. It is preferable to have two low voltage supply transformers 100 as shown. Accordingly, it is assumed that the portable electric railway failure point expression test apparatus according to an embodiment of the present invention is provided with two low voltage supply transformers 100 .

Referring to Figure 1, the portable electric railway failure point expression test apparatus according to an embodiment of the present invention is a low voltage supply transformer capable of outputting low voltage test power of multiple levels (AC 50V, 110V, 220V, 380V, 440V) ( 100) and; Switches 200 connected to the output terminal of each of the low voltage supply transformers 100 to regulate a power supply path, and a current detection current transformer (CT) connected in series to the low voltage supply transformers 100 and Using the impedance from the reference point to the fault point using the measurement units 300 for up and down lines including a transformer for voltage detection (PT) connected in parallel, and the current and voltage values obtained from each of the measurement units 300 , The controller 500 that calculates and outputs the distance to the fault point and the external power of 380V AC are connected to the primary side of the low voltage supply transformers 100, and the test site (eg, a substation or auxiliary section) or section) includes a cable coupling unit 400 and an operation panel unit 600 for electrically connecting the primary side of the autotransformer AT with the output terminal of each of the low voltage supply transformers 100 .

In the embodiment of the present invention, the controller 500 has been exemplified as performing the function of the failure point expression unit for calculating the distance to the failure point, but this is the operation of the failure point expression unit and the device as a whole depending on the implementation method, for example, a switchgear Operations such as (200) control, various display data display control, transformer 100 alternating control, etc. may be dualized into a device control unit that controls based on control data stored in the internal memory.

For reference, the primary side of each of the low voltage supply transformers 100 is connected to an external power input terminal of 380 V AC, and taps for outputting a plurality of different levels of low voltage are provided at the secondary output terminal, so that the controller 500 Controls the failure point expression test by controlling the power supply path so that the low voltage test power output from the tap of the provided low voltage supply transformers 100 is supplied to the primary side of the autotransformer located at the test site. can do. That is, the controller 500 selects an output terminal of any one of the two low voltage supply transformers 100 so that the low voltage test power output therefrom is supplied to the primary side of the autotransformer AT of the test site. 200) is controlled.

However, in order for the controller 500 to control the appropriate power supply path, the test voltage may be selected according to the distance of the expression test location from the test site (substation or auxiliary substation or substation). In this case, the device user selects a test voltage of a low voltage level through the operation panel unit 600 according to the distance.

For example, if the distance from the test site to the location of the facial expression test is within 3km, it is preferable to select AC 50V, and if it is 15 to 20km, it is preferable to select AC 380V as the test power source. In this way, the controller 500 intermittently controls the output path (ie, the power supply path) of the low voltage supply transformers 100 so that the test power of the low voltage level selected by the device user through the operation panel unit 600 is output. .

In the embodiment of the present invention, an example has been described in which different levels of low voltage can be used as a test power source according to the distance of the expression test location, but the test device is simply configured so that a single level of low voltage is output as the test power source, and the distance of the expression test location It may be possible to ensure that a suitable test device is used.

In some cases, the controller 500 may control the low voltage supply transformers 100 provided for each failure point expression test to alternately operate. The reason for doing this is that the fault point expression test itself is similar to the short circuit test, so if a single transformer is provided, a problem may occur in the transformer, shortening the life of the test device itself, or may not be able to operate normally during the test. Therefore, in order to improve the durability and reliability of the device, it is preferable to provide a plurality of transformers 100 to alternately operate each time a failure point expression test is performed. To this end, the controller 500 may count and record the operation sequence and select the operation transformer 100 based on this.

On the other hand, the portable electric railway failure point expression test apparatus according to an embodiment of the present invention having the above-described configuration may further include a safety ground fault device 700 as a separate configuration.

In this case, the switch driving unit may include a wireless communication unit for wirelessly receiving a ground fault and release command.

Additionally, the controller 500 sequentially transmits a message guiding a test method so that device users can conveniently perform a failure point expression test through the display window of the operation panel unit 600 based on the data stored in the internal memory. You can also indicate This will be described in more detail with reference to FIG. 8 .

As shown in FIG. 2, on one side of each switch 200 for simultaneous power supply, current detection current transformers CT and voltage detection transformers PT constituting the measurement unit 300 are connected in series and in parallel, respectively. , to the low voltage supply transformer, current detection current transformers CT are respectively connected in series and voltage detection transformers PT are respectively connected in parallel, the current detection current transformer CT and voltage detection transformer The controller 500 that calculates the distance from the reference point to the failure point using the reactance from the reference point to the failure point using the current and voltage values obtained from the PTs and outputs it through the display window is connected.

In this way, the safety ground fault device ( 700) will be installed to further explain the case of performing the failure point expression test.

First of all, Figure 5 illustrates the connection state of the safety ground fault device 700, which is one component of the portable electric railway failure point expression test device according to an embodiment of the present invention, and Figure 6 is the safety ground fault device 700 in Figure 1 7 is a view illustrating the connection state of one end of the ground wires connected to the safety ground fault device 700 in FIG. 1, respectively.

The safety ground fault device 700 has a portable box-shaped exterior as shown in FIG. 6 , and 'ground fault' and 'release' buttons that can be manipulated by the device user are exposed on the housing body. This safety ground fault device 700 is a ground wire first connection terminal 712 connected to the other side of the first ground line 710, one side of which is connected to the catenary, as shown in FIGS. 5 and 7 (a), As shown in (b) of FIG. 7 , a second connection terminal 722 of a ground line connected to the other side of a second ground line 720 having one side connected to the rail, and the first connection terminal 712 and a second connection It includes a ground fault switch (MGC) connected between the terminals 722 to open and close, and a switch driver (refer to FIG. 6 ) for controlling the opening and closing of the ground fault switch according to a ground fault and release command.

Hereinafter, a method for performing a failure point expression test using the portable electric railway failure point expression test device having the above-described configuration and the safety ground fault device 700 as an accessory thereof will be described.

First of all, since the failure point expression test consists of steps that must be performed sequentially at the test site and the railroad side, it is preferable to be performed by a person who has been trained in the failure point expression test. Since this can act as a constraint (human restrictions, education completion restrictions, etc.) It is desirable to induce the expression test to be made.

Accordingly, in the following, a process of performing a failure point expression test according to a message guided by a portable electric railway failure point expression test device will be described in detail with reference to FIG. 8 . 8 is a flowchart illustrating a failure point expression test guide using a portable electric railway failure point expression test apparatus according to an embodiment of the present invention. For reference, the test site in the following shall mean a substation. Such a test site may be any one of a substation, an auxiliary substation, and a substation. In addition, the sequentially displayed instruction messages can be programmed to be sequentially displayed according to a manipulation command of the device user.

Referring to Figure 8, the controller 500 of the portable electric railway failure point expression test device based on the data stored in the internal memory 'open the test site, for example, the power supply breaker of the substation (off) and low voltage level test Connect the output terminal of the transformer 100 that supplies power to the primary side bushing of the auto-transformer (AT) of the substation, which is the test site. give. In some cases, a message instructing the user of the device to connect an external power source to the portable electric railway fault point expression test device may be displayed together.

According to this instruction message, the device user uses the external power input cable and the output power cable to perform the portable electric railway fault point expression test device according to the embodiment of the present invention with the AT (autotransformer) primary side and external power source of the substation, which is the test site. connect

Thereafter, in response to the device user command, the controller 500 instructs 'installation of the safety ground fault device 700 in the 'on' state of the ground fault switch (MGC) of the safety ground fault device 700 at the expression test position of the electric train line. message is displayed (step S20). Accordingly, the device user delivers the message displayed in step S20 to the operator located at the test location of the catenary through wired and wireless communication. Accordingly, the operator turns on the ground fault switch (MGC) of the safety ground fault device 700 and then connects one side of the first ground line 710 to the catenary as shown in FIG. 7 and connects the other side to the safety ground fault device. Connected to the ground wire first connection terminal 712 provided in 700, one side of the second ground wire 720 is connected to the rail, and the other end is connected to the ground wire second connection terminal 722 provided in the safety ground fault device 700. connect to

As such, when the installation of the safety ground fault device 700 is completed, the device user and the operator confirm the installation of the safety ground fault device 700 through communication. When a command for the next step is issued through this check operation, the controller 500 checks the blackout state of the catenary and displays a message instructing to open the switchgear (MGC) (step S30). Accordingly, the device user instructs a worker located on the side of the catenary to open the switchgear (MGC), and the operator opens the switchgear (MGC).

After that, when the controller 500 commands the next instruction in response to the device user command, the controller 500 displays a message instructing to select a test power source according to the distance of the expression test location from the substation, which is the test site (step S40). . Accordingly, when the device user selects one of the test powers of 50,110,220,380,440V AC 50,110,220,380,440V, which is a low voltage level, the controller 500 provides two After switching-on control of the switch 200 connected to the output terminal of the transformer 100 to be operated according to a predetermined sequence among the transformers 100 for supplying low voltage, the test power application state is displayed (step S50).

When the test power application state is displayed in this way, the controller 500 displays a 'Ground fault by turning on the ground fault switch (MGC) of the safety ground fault device 700 after 5-6 seconds after confirming the test power application' (S60). step) do. Thereby, the device user instructs the worker located on the catenary side to put in the ground fault switch (MGC) of the safety ground fault device 700 through wired and wireless communication, and the field worker causes the ground fault switch (MGC) to be grounded. operate the button for

In this way, when a ground fault switch (MGC) is put in to artificially cause a ground fault in a catenary, the protective relay operates in the substation to open the test power supply circuit breaker, as well as the failure point expression device installed in the substation, the test site, and the present invention. The portable electric railway failure point expression test apparatus according to an embodiment performs each failure point expression calculation and displays it.

Accordingly, the device user is in a state in which the accuracy of the failure point expression device installed in the substation can be checked by comparing the displayed fault point expression calculations with each other. Thereafter, the controller 500 displays a message instructing 'confirm the test completion and release the switchgear (MGC) of the safety ground fault device 700' (step S70). Accordingly, the device user commands the operator located on the side of the catenary to release the switchgear (MGC) through wired and wireless communication and orders the removal of the grounding wires 710 and 720 connected to the catenary and rail, The test is finally finished. According to the failure point test method as described above, in order to verify the accuracy of the failure point expression device, the present invention is compared to the previous method of performing the failure point expression test by forcibly grounding a catenary of an extra high voltage (AC 25 kV) to verify the accuracy of the failure point expression device. Because it uses a low voltage level test power of 50 to 440V AC, it is possible to suppress the fault current, and it does not adversely affect the heavy electric equipment of the power supply system, train signal/communication facilities, etc. There is an advantage that can be performed, and there is also an advantage that the accuracy of the expression of the failure point can be dramatically improved through these repeated tests.

In addition, the portable electric railway failure point expression test apparatus according to an embodiment of the present invention has the advantage that it can be applied to both the suction current ratio method and the reactance method, and the present invention is a safety ground fault device for a catenary where AC 25kV power is cut off above all else. After installing the grounding hook of 700, after confirming that the test power is applied, after about 5-6 seconds, the switchgear (MGC) constituting the safety ground fault device 700 is turned on (on) to ground the catenary, so the inrush current is By preventing it from being included in the fault current, there is an advantage in that it is possible to measure the performance (impedance) of the fault point expression device more accurately.
