Discussed in 90m.
上記従来技術は、コイルに電流を流し、磁場を発生させ

を駆動していた。しかし、コイルには銅などの金属を用
いるため、コイルは内部抵抗をもつ。コイルに電流を流
そうとすると、この内部抵抗によりジュール熱による電
力消費と電圧降下が必ず発生するという問題があった。In the above-mentioned prior art, the armature is operated by passing a current through the coil to generate a magnetic field, thereby driving the switch. However, since the coil uses metal such as copper, the coil has internal resistance. When trying to pass current through the coil, this internal resistance inevitably causes power consumption and voltage drop due to Joule heat.
本発明の目的は、この消費電力と電圧降下を減少させ、
低消費電力、低部電圧で動作できる電磁駆動゛式スイッ
チを提供することにある。The purpose of the present invention is to reduce this power consumption and voltage drop,
An object of the present invention is to provide an electromagnetic drive type switch that can operate with low power consumption and low voltage.
上記目的は、コイルの線材として超伝導体を用いること
により達成できる。The above object can be achieved by using a superconductor as the wire of the coil.
通常の金属は内部抵抗を持つため、電流を流した時にジ
ーール熱を発生し、電力を消費する。また、オームの法
則にしたがい、電圧を降下させる。Ordinary metals have internal resistance, so when electric current is passed through them, they generate heat and consume electricity. Also, the voltage is dropped according to Ohm's law.
一方、超伝導体は臨界温度以下では内部抵抗が零になる
ため、ジュール熱や電圧降下を発生しない。よって、コ
イルに超伝導体を用いると、低い電圧でも大電流を流す
ことができ、低電圧駆動と低消費電力化が達成できる。On the other hand, superconductors have zero internal resistance below their critical temperature, so they do not generate Joule heat or voltage drop. Therefore, if a superconductor is used for the coil, a large current can flow even at a low voltage, and low voltage driving and low power consumption can be achieved.
ところが、Nb3Snのような金属系超伝導体を用いた

系超伝導体を用いれば、簡単な冷却装置で超伝導状態に
することができ、上記構造を実現できる。However, when a metallic superconductor such as Nb3Sn is used, the superconductor cannot be taken out of a liquid helium container or the like, and the above structure cannot be realized. However, if a nonmetallic superconductor whose main components are il-IJium, barium, lanthanum, strontium, copper oxide, etc. is used as a superconductor, it can be brought into a superconducting state with a simple cooling device. The above structure can be realized.
以下実施例により本発明を説明する。 The present invention will be explained below with reference to Examples.

The contact 5 of this IJ-type switch is opened and closed by the magnetic field generated by the superconducting coil, and the current is interrupted. The superconducting coil] is immersed in liquid nitrogen 4 and cooled below the critical temperature.

上記構造のリレーでは、超伝導コイル1の内部抵抗が零
となるため、低電圧駆動と低消費電力化が可能である。When a current is passed through the superconducting coil 1, a strong magnetic field is generated inside the fixed core 9, which attracts the movable core 8 and makes the contact 5 clear. When the current flowing through the superconducting coil 1 is cut off, the contact 5 returns to its original state due to the spring 7. In this way, the signal at the terminal 6 is switched. Furthermore, the relay is surrounded by a superconducting shield 10, and the whole is immersed in liquid nitrogen 4 to maintain the superconducting state. In the relay with the above structure, the internal resistance of the superconducting coil 1 is zero, so low voltage It is possible to drive and reduce power consumption.
