Description

Grounding information management device using QR code and its method {APPARATUS AND METHOD FOR MANAGING EARTHING INFORMATION USING QR CODE}

The present invention relates to an apparatus and method for managing grounding information using a QR code, and more particularly, by using a QR code to manage the grounding information of the grounding point for not only GIS grounding, but also human grounding, communication between the operator and the operator. In order to facilitate and increase the convenience of facility management, it relates to an apparatus and method for managing grounding information using a QR code.

In general, gas insulated switchgear (GIS) is installed between the circuit between the power side and the load side of the electric system, so that abnormal currents such as ground faults or short circuits occur on the circuit when artificially opening and closing the circuit under normal current conditions. It is an electric device that protects the power system and load by safely blocking the current when it is done.

This GIS consists of a bushing that receives power from a high-voltage power source, a circuit breaker (CB), a disconnector switch (DS), and an earth switch (ES).

In particular, the grounding switch (ES) is installed at both ends of a circuit breaker to manually ground the main circuit during maintenance and inspection, and is a device that removes the current remaining in the conductor during maintenance or inspection.

1 is a view for explaining a single-line state of GIS grounding and personnel grounding.

Referring to FIG. 1, since GIS grounding using a grounding switch (ES) is displayed on a SCADA (Supervisory Control And Data Acquisition) and a single line diagram, an operator and an operator can check it (see A in FIG. 1).

On the other hand, in the case of manpower grounding using a ground wire that receives the current generated from the power facility and discharges it to the ground, it is difficult for the operator and the operator to check each other because it is not marked on the SCADA and single-line diagram (see Fig. 1B). .

In this case, confusion may occur at the grounding point due to confusion in communication between the operator and the operator during the ceasefire operation.

Moreover, in the case of a large number of grounding points, the location of the grounding points may be lost, so there is a high possibility of accidents with the facility when the facility is pressurized without the grounding removed.

Therefore, in the case of implementing the grounding method, it is possible to accurately recognize the grounding point even for personal grounding, such as GIS grounding, and through this, a plan to share the grounding point and special matters between the worker and the operator is prepared, and the facility And it is necessary to prevent the occurrence of personal accidents.
