Description

この発明は、低圧配電線路に設けた漏電遮断機(ブレーカー)等の検電検相を行う際、検電検相器(以下、単に検相器と言う)の入力端子とブレーカー等の端子とを接続するアダプタに関するものである。 The present invention provides an input terminal of a voltage detector (hereinafter simply referred to as a phase detector) and a terminal of a breaker, etc. Is related to the adapter to connect.

従来、検相器の入力端子から導出した3相のリード線のプローブ部分がクリップ式となっており、ブレーカーの種類によってはクリップが端子から外れやすかったり、クリップそのものが使用できないものもある。そのため、ブレーカー等の検電検相を行う際は、通常、一人の作業者がブレーカーの2相の端子に2相のクリップ部分を接触させ、他の一人の作業者が片方の手で他の1相の端子に1相のクリップ部分を接触させ、さらに、他の片方の手で検相器を操作して検電検相を行う2人体制で行わなければならなかった。 Conventionally, the probe portion of the three-phase lead wire derived from the input terminal of the phase detector is a clip type, and depending on the type of breaker, the clip may be easily detached from the terminal or the clip itself cannot be used. For this reason, when performing phase detection and phase detection for a breaker, etc., one worker usually makes the two-phase clip part contact the two-phase terminal of the breaker, while the other worker uses the other hand to A one-phase clip portion was brought into contact with the one-phase terminal, and further, it was necessary to perform a voltage detection / phase detection by operating the phase detector with the other hand.

このような検査を迅速に行うために検相器のクリップ部分にアダプタを取り付け、一人の作業者で安全かつ正確に検電検相等の検査を行うことができるようなアダプタの開発が望まれている。 In order to perform such inspection quickly, an adapter is attached to the clip portion of the phase detector, and it is desired to develop an adapter that can perform inspection such as electric detection and phase detection safely and accurately by a single operator. Yes.

また一方、前記ブレーカーの3相の端子の間隔は、機種によって異なっているため、前記アダプタはこれらの多機種のブレーカーに適用できることが必要である。そんな中、特許文献1に示す三相交流検相器用テストリードが開発されている。 On the other hand, since the interval between the three-phase terminals of the breaker differs depending on the model, the adapter needs to be applicable to these many types of breakers. Meanwhile, a test lead for a three-phase AC phase detector shown in Patent Document 1 has been developed.

この特許文献1に示すものは、片手で安全に保持し、三相交流の被接触端子台に正確に接触させることができるように、三相を束ねて把持できるグリップ部分4を設け、また、当該グリップ部分4から導出したリード線に、指を差し込み、操作できるようリング状にした部分3をそれぞれ設け、さらに、テストリード線の相間隔を指で調整できるようにリング状部分2を設けたものである。 The one shown in Patent Document 1 is provided with a grip portion 4 that can be held and bundled in three phases so that it can be safely held with one hand and brought into contact with a three-phase AC contacted terminal block accurately. The lead wire led out from the grip portion 4 is provided with a ring-shaped portion 3 so that a finger can be inserted and operated, and a ring-shaped portion 2 is provided so that the phase interval of the test lead wire can be adjusted with the finger. Is.

またさらに、三相交流検相器用テストリードの各相の先端部分に、電気的接触を確実にするため、伸縮性円筒状ゴムの内部に2組の編銅線を巻き込み、先端部分に差し込める部品を装着させることもでき、また、先端部分に差し込み、装着できるスプリング機能を持たせた部品を前記部品に代えて装着できるようにしたものである。 Furthermore, in order to ensure electrical contact with the tip of each phase of the test lead for the three-phase AC phase detector, two sets of braided copper wires are wound inside the elastic cylindrical rubber and can be inserted into the tip. A component can be mounted, and a component having a spring function that can be inserted and mounted at the tip portion can be mounted instead of the component.

しかしながら、特許文献1のものは、ブレーカーの3相の端子に一度に接触できるようにグリップ部分4から3相のテストリード線が導出しており、作業者はグリップ部分4を持ってブレーカーの3相の端子に接触させる構成となっている。従って、グリップ部分4を作業者が握って、これらの3相のテストリード線の先端をブレーカーの各端子に押し付けなければならず、それ故、各テストリード線はある程度の剛性を有するものでなければならない。 However, in Patent Document 1, a three-phase test lead wire is led out from the grip portion 4 so that the three-phase terminals of the breaker can be contacted at a time. It is the structure which contacts the terminal of a phase. Therefore, the operator must hold the grip portion 4 and press the tips of these three-phase test leads against the terminals of the breaker. Therefore, each test lead must have a certain degree of rigidity. I must.

一方、ブレーカーの3相の各端子の間隔によっては、前記リング状部分2に指を入れて、テストリード線の相間隔を調整するため、検相器の操作中においても指に力を入れて、テストリード線の間隔を保持しなければならず、ブレーカーの3相の端子へのテストリード線の先端の接触が極めて不安定となる恐れがある。 On the other hand, depending on the distance between the three-phase terminals of the breaker, a finger is put into the ring-shaped portion 2 to adjust the phase distance of the test lead wire. The distance between the test lead wires must be maintained, and the contact of the tip of the test lead wire with the three-phase terminal of the breaker may become extremely unstable.

そこで、この発明はこの様な従来の課題を解決し、ブレーカー等の3相の端子の間隔に合わせて、アダプタの3相のプローブの間隔を調節、固定し、この状態で各プローブをブレーカー等の3相の端子に容易かつ確実に接触させることができる、検電検相器入力用アダプタ及びこれを用いた検電検相方式を提供することを目的としたものである。 Therefore, the present invention solves such a conventional problem, and adjusts and fixes the interval between the three-phase probes of the adapter in accordance with the interval between the three-phase terminals of the breaker or the like. It is an object of the present invention to provide a voltage detector / phase detector input adapter that can be easily and reliably brought into contact with the three-phase terminals and a voltage detection / phase detection method using the adapter.

Therefore, when the operator holds the gripping piece and presses each probe against each of the three-phase terminals such as a breaker, each probe surely comes into contact with the terminal due to the repulsive force of each spring.

また、請求項4の発明によれば、各可動端子体は2枚の波型ガイド板の上下の波型溝内に挟まれているため、作業者の力で各可動端子体を引っ張ると各波型ガイド体を弾性力により変形させて移動させることができ、また、前記引っ張りを止めると、2枚の波型ガイド板の対向する上下の波型溝に嵌り、自動的に固定される。従って、各可動端子体の摺動及び固定が極めて容易である。 According to the invention of claim 4, since each movable terminal body is sandwiched between the upper and lower corrugated grooves of the two corrugated guide plates, each of the movable terminal bodies is pulled by the operator's force. The wave guide body can be deformed and moved by elastic force, and when the pulling is stopped, the wave guide body is fitted into the upper and lower wave grooves facing each other and automatically fixed. Accordingly, the sliding and fixing of each movable terminal body is extremely easy.

また、請求項5の発明によれば、各スプリングバネの力により各プローブは筒状体内に引っ込む方向に付勢されているため、各プローブは常に筒状体に被われており、検電や検相の測定中に作業者等が、プローブに触れることが無く、安全である。また、作業者が、前記把手片を持ってブレーカー等の3相の各端子に各筒状体を押し付けた際、各バネの反発力により確実に各プローブは各筒状体の先端面まで突出し、各プローブの先端面は各端子に圧接し、電気的接触を確実にする。 According to the invention of claim 5, since each probe is biased in the direction of retracting into the cylindrical body by the force of each spring spring, each probe is always covered with the cylindrical body, An operator or the like does not touch the probe during the phase detection measurement and is safe. Further, when the operator holds the handle piece and presses each tubular body against each of the three-phase terminals such as a breaker, each probe surely protrudes to the tip surface of each tubular body by the repulsive force of each spring. The tip surface of each probe is in pressure contact with each terminal to ensure electrical contact.
