生時ディーゼル発電装置の即時起動を行うことが出来な
い事態が生じるという欠点があった。Among this type of power generation equipment, those used as emergency power generation equipment for disaster prevention, for example, are equipped with a constant preheating device to facilitate immediate startup. However, because only a zero current detector was installed, even if an abnormality due to a disconnection of the preheating plug could be detected, the abnormality due to a short circuit would be overlooked, and the diesel generator would be activated immediately in the event of a disaster. The disadvantage was that there were situations in which it was not possible to do so.
この考案は、上記した従来の欠点を除去する為になされ

熱栓異常検出装置を提供することを目的とする。This idea was made in order to eliminate the above-mentioned drawbacks of the conventional method, and by using a dual-operation current relay, it is possible to reliably detect not only abnormalities due to disconnection of the preheating plug, but also abnormalities due to short circuits. An object of the present invention is to provide a preheating plug abnormality detection device for a diesel power generation device that can detect abnormalities in a preheating plug of a diesel power generator.
以下、この考案の一実施例を図について説明する。An embodiment of this invention will be described below with reference to the drawings.

源２の両端子間に接続されている。In the figure, reference numeral 1 denotes a preheating plug or resistance heating element disposed in a diesel engine of a diesel power generator, and is connected between both terminals of a power source 2 for preheating.
３は変流器、４は２他動作の電流継電器で、予熱栓１に

流が上限及び下限動作値を超えた場合に警報器５の図示
しない入力回路を閉成する構成となっている。3 is a current transformer, 4 is a current relay with two other operations, and an upper limit operating value and a lower limit operating value are set based on the output of the current transformer 3 when the rated current flows into the preheating plug 1, It is configured to close an input circuit (not shown) of the alarm 5 when the input current exceeds the upper and lower operating limits.
従って、この構成では、予熱栓１に短絡が生じ短絡電流
が流れると、上限動作値を超える電流が電流継電器４に
入力され、警報器５が作動する。Therefore, in this configuration, when a short circuit occurs in the preheating plug 1 and a short circuit current flows, a current exceeding the upper limit operating value is input to the current relay 4, and the alarm 5 is activated.
また、予熱栓１が断線した場合には電流継電器４の入力
電流が下限動作値以下となる為警報器５が作動する。Further, when the preheating plug 1 is disconnected, the input current of the current relay 4 becomes less than the lower limit operating value, so the alarm 5 is activated.
以上のように、この考案によれば、入力電流が一定の範

に即時起動しうる状態に置くことができる。As described above, according to this invention, a current relay with two different operations that operates when the input current exceeds a certain range is used.
Since this current relay is configured to supply a current corresponding to the current flowing into the preheating wire, it can automatically detect not only a disconnection of the preheating plug but also a short circuit, ensuring that the diesel generator can always be started immediately. can be placed in
