Abstract
A cable condition monitoring device for monitoring a damaged condition of a cable including a conductor part including a plurality of element wires and an insulating material part formed on a periphery of the conductor part includes a gas feeding device configured to feed a compressed gas into the conductor part, a pressure gauge configured to measure a pressure in the conductor part, and an insulating material part damage judgment part configured to judge whether the insulating material part is damaged or not based on the pressure measured by the pressure gauge.
Claims6
A cable condition monitoring device for monitoring a damaged condition of a cable comprising a conductor part comprised of a plurality of element wires and an insulating material part formed on a periphery of the conductor part, comprising:
- a gas feeding device configured to feed a compressed gas into the conductor part;
- a pressure gauge configured to measure a pressure in the conductor part;
- and
- an insulating material part damage judgment part configured to judge whether the insulating material part is damaged or not based on the pressure measured by the pressure gauge.
A cable condition monitoring system, comprising:
- a cable comprising a conductor part comprised of a,plurality of element wires and an insulating material part formed on a periphery of the conductor part;
- a gas feeding device configured to feed a compressed gas into the conductor part;
- a pressure gauge configured to measure a pressure in the conductor part, and an insulating material part damage judgment part configured to judge whether the insulating material part is damaged or not based on the pressure measured by the pressure gauge,
- wherein the cable further comprises a metal terminal attached to each end of the cable and comprising a conductor part swaging part configured to swage and fix the cable inserted from a cable insertion opening and a gas feeding discharging opening configured to be communicated with the cable insertion opening internally so as to feed or discharge the compressed gas, and
- wherein the gas feeding device is connected to the gas feeding discharging opening of one terminal and is configured to feed the compressed air into the conductor part via the one terminal.
