Description

Technology Field

[0001] The present invention relates to a railway power receiving device that includes power quality improvement, and more specifically, to a railway power receiving device that enables rapid maintenance by detecting heat or leakage current caused by overheating in a receiving board and power cable connected to a power cable by the receiving device and transmitting a detection signal, thereby preventing power quality degradation caused by uneven power supply, power interruption, or fluctuation in power amount due to heat or leakage current, and preventing fire caused by overheating or safety accidents caused by leakage current, improving the support and fixing strength of the receiving board and cushioning the transmission of external shocks, and fixing the power cable when overheating or fire occurs to prevent the power cable from moving when the power cable is cut by overheating or fire, thereby preventing the fire from spreading as the power cable moves and preventing safety accidents. Background Technology

[0003] Generally, an electric railway is a railway that operates trains or vehicles on tracks using electricity as a power source, and it is divided into DC electric railways and AC electric railways depending on the electrical system.

[0004] These electric railways operate by receiving electricity through overhead lines, and overhead lines are facilities for directly supplying power to the pantographs (current collection devices) of electric vehicles (trains) that serve as loads; they can be defined as a collective term for overhead line facilities such as overhead lines and facilities attached thereto.

[0005] Overhead lines can be classified into overhead systems and third rail systems depending on the method of supplying electricity, and the overhead lines can be further classified into catenary systems and rigid systems. These overhead lines are connected to frames or power posts formed along the electric railway tracks to supply power to the trains.

[0006] The aforementioned overhead line is provided on the railway, and a receiving board that receives power from an external source and a substation that receives power from the receiving board and supplies electricity to the overhead line are installed.

[0007] However, conventional power receiving panels connected to power cables lack separate means to detect and report status information regarding heat and leakage caused by overheating in the power cables and receiving panels. Consequently, power supply is uneven, power is interrupted, or the amount of power fluctuates due to heat or leakage in the power cables and receiving panels, leading to degraded power quality and frequent occurrences of fires caused by overheating or safety accidents caused by leakage. Additionally, there are no separate means to protect the receiving panels, resulting in damage to internal power equipment due to external forces or impacts. Furthermore, there are no separate means to secure the power cables in the event of a fire caused by overheating, leading to persistent problems where the fire spreads or safety accidents occur as the fire-affected power cables and the power cables transmitted by the fire move.

[0008] The aforementioned invention refers to background technology in the technical field to which the present invention belongs, and does not refer to prior art. Prior art literature

[0064] That is, the above-mentioned shooting information transmitted through the above-mentioned transmitter / receiver (97) is received through a manager terminal or a central management server to determine the dangerous condition of the worker and take prompt action, and if a fire occurs during the installation process, prompt action is possible to prevent the fire from spreading.

[0065] In addition, the thermal imaging camera (96) moves up and down and rotates while taking pictures by means of the lifting detection cylinder (92) and the driving detection motor (94), thereby expanding the shooting range compared to a fixed structure and increasing shooting efficiency.
