Description

本発明は、アース対象物をアースするためのアース装置に関する。 The present invention relates to a grounding device for grounding a grounding object.

揮発性の有機溶剤を貯蔵するための容器や、高電圧が印加される装置には、帯電を防止し、除電するためのアース装置が接続される場合がある。 A container for storing a volatile organic solvent and a device to which a high voltage is applied may be connected to a grounding device for preventing charging and removing electricity.

アースによって、例えば、有機溶剤を扱うときに、容器が帯電して静電気が発生し、有機溶剤に引火することや、例えば、高電圧が印加される装置を除電して、感電を防止することができる。 For example, when handling organic solvents, the container can be charged and static electricity is generated, and the organic solvent can be ignited, or the device to which a high voltage is applied can be neutralized to prevent electric shock. it can.

このようなアース装置として、例えば、アース線を介して接地される接地棒と、絶縁物を介して接地棒に連結されるとともに、リード線を介して接地される補助電極と、リード線の途中に設けられる表示灯とを備え、接地棒とともに補助電極も高電圧ボックスに当接させて、電源から、表示灯、リード線、補助電極、高電圧ボックス、接地棒、アース線、大地電位部を介して電源に戻る閉ループを形成することにより、表示灯を点灯させる接地装置が提案されている（例えば、特許文献１参照。）。 As such a grounding device, for example, a grounding rod grounded via a ground wire, an auxiliary electrode coupled to a grounding rod via an insulator, and grounded via a lead wire, and a middle of the lead wire The indicator lamp, lead wire, auxiliary electrode, high voltage box, grounding rod, grounding wire, and ground potential section are connected to the high voltage box together with the grounding rod. There has been proposed a grounding device that turns on an indicator lamp by forming a closed loop that returns to a power source (see, for example, Patent Document 1).

この接地装置によれば、高電圧ボックスが接地棒により接地されていないと、表示灯が消灯する。そのため、高電圧ボックスが接地棒により接地されていることを、容易に確認することができる。 According to this grounding device, when the high voltage box is not grounded by the grounding rod, the indicator lamp is turned off. Therefore, it can be easily confirmed that the high voltage box is grounded by the grounding rod.

特開平９−２１９２２６号公報Japanese Patent Laid-Open No. 9-219226

しかるに、特許文献１に記載の接地装置では、高電圧ボックスが接地棒により接地されていることを確認するためには、接地棒と補助電極との両方が高電圧ボックスに当接している必要があるところ、接地棒と補助電極とは、間隔を隔てて平行に配置されている。 However, in the grounding device described in Patent Document 1, in order to confirm that the high voltage box is grounded by the ground bar, it is necessary that both the ground bar and the auxiliary electrode are in contact with the high voltage box. In some cases, the grounding rod and the auxiliary electrode are arranged in parallel with a distance therebetween.

そのため、障害物の干渉などにより、高電圧ボックスに、接地棒および補助電極のいずれか一方のみが当接し、他方が当接しない場合を生じる。すると、例えば、高電圧ボックスに、接地棒が当接し、補助電極が当接しない場合には、接地棒により高電圧ボックスが接地されているにもかかわらず、表示灯が消灯してしまい、高電圧ボックスが接地棒により接地されていることを確認できないという不具合を生じる。 Therefore, there is a case where only one of the grounding rod and the auxiliary electrode is in contact with the high voltage box and the other is not in contact with the high voltage box due to interference of an obstacle. Then, for example, when the grounding rod is in contact with the high voltage box and the auxiliary electrode is not in contact with the high voltage box, the indicator lamp is turned off even though the high voltage box is grounded by the grounding rod. This causes a problem that it is not possible to confirm that the voltage box is grounded by the grounding rod.

そこで、本発明の目的は、アース対象物がアースされていることを確実に検知することができるアース装置を提供することにある。 Accordingly, an object of the present invention is to provide a grounding device that can reliably detect that a grounding object is grounded.

このアース装置は、アース側配線と、検知手段を備える検知側配線とを、常には導通されていない状態で備えており、アース側配線と検知側配線とは、アース側配線および検知側配線の一端部に設けられている装着部材がアース対象物に装着されることにより、導通される。また、アース側配線および検知側配線の他端部には、アース部材が設けられている。 This grounding device is provided with a ground side wiring and a detection side wiring provided with a detecting means in a state that is not always conducted. The ground side wiring and the detection side wiring include the ground side wiring and the detection side wiring. The mounting member provided at the one end is electrically connected to the grounding object. A ground member is provided at the other end of the ground side wiring and the detection side wiring.

そのため、装着部材がアース対象物に装着されることにより、アース対象物と、アース側配線および検知側配線との導通が確保される。 Therefore, when the mounting member is mounted on the ground object, electrical connection between the ground object and the ground side wiring and the detection side wiring is ensured.

これにより、検知側配線から、アース対象物、アース側配線を順次介してアース部材へ至る直列回路が形成され、検知側配線の導通を検知手段によって検知することによって、アース対象物がアース側配線によりアースされていることを、確実に、検知することができる。 As a result, a series circuit is formed from the detection side wiring to the earth member through the ground object and the earth side wiring in sequence, and the ground object is detected by detecting the continuity of the detection side wiring by the detecting means. Therefore, it is possible to reliably detect the grounding.
