Title:
COMPOSITE POWER CABLE IN WHICH HEAT SENSING WIRE IS EMBEDDED AND OVERHEAT PROTECTION DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2020/153647
Kind Code:
A1
Abstract:
The present invention relates to: a composite power cable in which a heat sensing wire is embedded, having a simple structure so as to facilitate installation and improve economic feasibility and, simultaneously, being capable of sensing heat generated inside and outside the power cable; and an overheat protection device comprising the composite power cable. According to the present invention, a composite power cable in which a heat sensing wire is embedded comprises: a dummy (100) extending to one side; at least one power feeding wire (200) which is helically wound on an outer circumferential surface of the dummy (100) in the direction in which the dummy (100) extends, and to which power is applied from an inverter so that a high-frequency current flows therein; at least one heat sensing wire (300) helically wound, together with the power feeding wire (200), on the outer circumferential surface of the dummy (100) in the direction in which the dummy (100) extends, so as to sense the heat generated from the power feeding wire (200); and a cable sheath (400) formed to encompass the power feeding wire (200) and the heat sensing wire (300) on the outside.
