HEAT GENERATION DETECTOR AND HEAT GENERATION DETECTION SYSTEM

To provide a heat generation detector and a heat generation detection system which can reliably detect heat generation of an object to be detected and easily confirm heat generation of the object to be detected.SOLUTION: A heat generation detector 2A is attached to a feeder wire F and detects heat generation of the feeder wire F. A heat generation detection part 3 detects the heat generation of the feeder wire F at a plurality of detection parts Pto Pwith intervals in a peripheral direction of an outer peripheral part of the feeder wire F. A plurality of opening/closing parts Sto Sopen/close when they receive heat exceeding a prescribed temperature from the respective detection parts Sto Sof the feeder wire F. An opening/closing state detection part detects open/closed states of the plurality of opening/closing parts Sto S. The plurality of opening/closing parts Sto Sare serially connected and open when they receive heat exceeding the prescribed temperature from the respective detection parts Sto Sof the feeder wire F. The opening/closing state detection part detects heat generation of the feeder wire F by detecting the opening state of the opening/closing parts Sto Sat the respective detection parts Sto Sof the feeder wire F.SELECTED DRAWING: Figure 2 【課題】検知対象物の発熱を確実に検知することができるとともに、検知対象物の発熱を容易に確認することができる発熱検知装置及び発熱検知システムを提供する。【解決手段】発熱検知装置２Ａは、き電線Ｆに装着されてこのき電線Ｆの発熱を検知する。発熱検知部３は、き電線Ｆの外周部の周方向に間隔をあけて複数の検知箇所Ｐ1〜Ｐ6で、このき電線Ｆの発熱を検知する。複数の開閉部Ｓ1〜Ｓ6は、き電線Ｆの各検知箇所Ｐ1〜Ｐ6から所定温度を超える熱を受けたときに開閉する。開閉状態検知部は、複数の開閉部Ｓ1〜Ｓ6の開閉状態を検知する。複数の開閉部Ｓ1〜Ｓ6は、直列接続されており、き電線Ｆの各検知箇所Ｐ1〜Ｐ6から所定温度を超える熱を受けたときに開く。開閉状態検知部は、き電線Ｆの各検知箇所Ｐ1〜Ｐ6の開閉部Ｓ1〜Ｓ6の開状態を検知することによって、き電線Ｆの発熱を検知する。【選択図】図２
