Description

  The present invention relates to a short-circuit grounding system and a short-circuit grounding program for knowing whether a short-circuit grounding device is grounded or removed.

  For example, when performing power outage work for the power distribution network, use a short-circuit grounding device to ensure that the target circuit is secured in order to prevent or avoid the risk of electric shock due to mis-energization, contact with other circuits, or induction from other circuits. Measures are taken to short-circuit the ground. In addition, when the power failure work is completed and the energized circuit is energized, it is energized in advance after confirming that there is no risk of electric shock to the operator and that the short-circuit grounding device has been removed. .

  However, since human removal and confirmation of the short-circuit grounding device is performed, there is a risk of forgetting or mistaken to remove or confirm the short-circuit grounding device. The part that was transmitting power will also be cut off. In particular, when a plurality of short-circuit grounding devices are grounded, there is a risk of forgetting to remove or check all the short-circuit grounding devices.

  Therefore, a ground state management device is known that can reliably avoid charging the grounded electric circuit (see, for example, Patent Document 1). This device includes a drive control unit that drives and controls the grounding device, a control-side terminal that is installed in the control station and transmits an operation signal to the drive control unit, and a short-circuit grounding device that is attached to a power transmission line between the electrical stations, A receiving device that is installed at each electric station and receives a signal from each short-circuit grounding device and transmits the signal to the control-side terminal. The short-circuit grounding device transmits a signal indicating the grounding state when the electric circuit is grounded, and the control-side terminal locks the operation by the drive control unit when receiving the signal indicating the grounding state. When the signal indicating the state is not received, the operation by the drive control unit is unlocked.

  By the way, in a power outage work or the like, a work supervisor or the like may want to know surely and accurately whether the short-circuit grounding device is grounded or removed. For example, there is a case where it is desired to know whether the short-circuit grounding device is grounded at a predetermined position according to the work procedure manual. In addition, it is desirable that a work supervisor or the like can be known at an arbitrary place and at an arbitrary time.

  However, in the past, since knowledge was obtained through confirmation and contact by a person, not only time and labor are required, but there is a risk of misrecognition or contact error. Moreover, in the technique of patent document 1, since the control side terminal is installed in the control station, the state of the short-circuit grounding device cannot be confirmed unless it is the control station.

  Accordingly, an object of the present invention is to provide a short-circuit grounding system and a short-circuit grounding program capable of flexibly and surely knowing whether the short-circuit grounding device is grounded or removed.

  In order to solve the above-mentioned problem, the invention of claim 1 is provided in the short-circuit grounding device connected to the electric circuit for grounding an uncharged electric circuit, the short-circuiting grounding device, and the electric circuit is provided by the short-circuiting grounding device. A detection transmitter that transmits a ground signal to the outside when the ground is grounded, and a release signal that is transmitted to the outside when the ground is released, and a display unit that is portable and communicated with the detection transmitter. A mobile terminal comprising: a specifying means for specifying the short-circuit grounding equipment by inputting identification information of the short-circuit grounding equipment; and a detection transmitter of the specified short-circuit grounding equipment. A short-circuit grounding system comprising: state display means for displaying state information indicating whether the short-circuit grounding device is grounded or removed based on the received grounding signal and release signal on the display unit. It is.

  According to the present invention, first, identification information of a short-circuit grounding device whose state is to be known is input by specifying means of the portable terminal to identify the short-circuiting grounding device. Next, when the electric circuit is grounded by the short-circuit grounding device, a ground signal is transmitted from the detection transmitter, and the display unit displays that the short-circuiting grounding device is grounded by the status display means of the portable terminal. . When the grounding by the short-circuit grounding device is released, a release signal is transmitted from the detection transmitter, and the display unit displays that the short-circuiting grounding device has been removed by the status display means of the portable terminal.

  According to a second aspect of the present invention, in the short-circuit grounding system according to the first aspect, the portable terminal includes a position acquisition unit that acquires a position where the short-circuit grounding device is grounded, and the status display unit is the position acquisition unit. The position acquired by the means is displayed on the display unit together with the state information on a map.

  According to a third aspect of the present invention, in the short-circuit grounding system according to the first or second aspect, the detection transmitter includes a camera for photographing the periphery, and when the release signal is transmitted, the image is photographed by the camera. Transmitting to the outside, the state display means displays the image received from the detection transmitter on the display unit together with the state information.

  According to a fourth aspect of the present invention, when a short-circuit grounding device connected to the electric circuit for grounding an uncharged electric circuit is grounded, a ground signal is transmitted to the outside when the electric circuit is grounded by the short-circuiting grounding device. A detection transmitter for transmitting a release signal to the outside when released is provided, and a short-circuit grounding program for knowing whether the short-circuit grounding device is grounded or removed, comprising: On the basis of the specifying means for specifying the short-circuit grounding equipment by inputting the identification information of the grounding equipment, and the ground signal and the release signal received from the detection transmitter of the specified short-circuit grounding equipment, It is made to function as a status display means for displaying status information indicating whether it is grounded or removed.

  According to the first aspect of the present invention, whether the short-circuit grounding device is grounded or removed is displayed on the mobile terminal in real time. Therefore, if the portable terminal is carried, the short-circuiting grounding device is grounded or removed. Can be known flexibly and reliably. That is, as long as the portable terminal is held, any person (anyone) can surely and accurately know whether the short-circuit grounding device is grounded or removed at any time and at any place.

  On the other hand, a short-circuit grounding device whose state is to be known is specified in advance, and state information is displayed based on a signal from the detection transmitter of this short-circuiting grounding device. In other words, since the status display of unspecified short-circuited grounding equipment that does not need to be identified (no need to know the status) is not displayed, even if a short-circuiting grounding equipment that is not subject to use is used, the short-circuited grounding equipment you want to know It is possible to know only the state of this easily and reliably. Moreover, any short-circuit grounding device can be specified by inputting identification information of the short-grounding device whose state is to be known. That is, even if an arbitrary short-circuit grounding device is used, the state can be surely and accurately known only by inputting the identification information.

  As a result, the ground leakage (forgetting) of the short-circuit grounding equipment is eliminated, the safety of the operator is ensured, the removal leakage of the short-circuit grounding equipment is eliminated, and a wide-range power outage from the substation can be prevented. Further, it is possible to prevent an electric shock when a power is transmitted during removal of the short-circuit grounding device and a burn caused by a short-circuit arc. Further, since confirmation and communication by a person is not necessary, not only can time and labor be remarkably reduced, but also misidentification and communication mistakes can be eliminated, and erroneous operations and work can be prevented.

  According to the invention of claim 3, when the grounding by the short-circuit grounding device is released, a peripheral image photographed by the camera is displayed together with the state information (the short-circuiting grounding device has been removed). For this reason, it is possible to accurately confirm whether or not the short-circuit grounding device is surely removed by viewing the image.

  According to the invention of claim 4, as long as the computer (mobile terminal) having the short-circuit grounding program is possessed, as in the invention of claim 1, an arbitrary person is in an arbitrary place at an arbitrary time, It is possible to reliably and accurately know whether the short-circuit grounding device is grounded or removed. In addition, since this short-circuit grounding program only needs to be provided in a general-purpose computer, it is possible to know the state of the short-circuit grounding device reliably and accurately by utilizing existing and existing computers.
