せるコイルにより電気的に接続して構成されている。In recent years, by applying an axial magnetic field parallel to the arc, the arc is dispersed on the electrode surface, preventing its local concentration, and thereby improving the breaking performance by preventing excessive melting of the electrode. A so-called vertical magnetic field type vacuum interrupter is known, which aims at A cap-shaped disk-shaped electrode consisting of a contact part and an arc diffusion part is mechanically fixed to the inner end of the electrode with an insulating spacer interposed, and each electrode and the inner end of the electrode rod are arranged on the back of the electrode. It is electrically connected by a coil that converts the axial current flowing through the electrode rod into a loop current centered around the electrode rod to generate an axial magnetic field.

いる。However, the electrodes of the conventional vertical magnetic field type vacuum interrupter are made of Ou and Ou containing 0.5 weight factor of B1 (hereinafter referred to as "0u-0.5Bi alloy"), which has a relatively high electrical conductivity (approximately 100% conductivity), or 20%

っている。However, in the case of the former (3u and 0u-0,5Bi alloys), due to the high conductivity, the generation of eddy current becomes noticeable, leading to a decrease in the strength of the axial magnetic field, and We are trying to solve this problem by providing multiple slits.

問題がある。However, the electric field is concentrated at the edge of the slit, resulting in a decrease in the dielectric strength of the current cutter and the dielectric strength after the cutoff.Especially in the case of eu-0,5B1 alloy, its vapor pressure is high, so the current cutter The dielectric strength of the blade after cutting is reduced by -), and the multiple slits cause a reduction in mechanical strength.The current cutting value is as high as IOA, so it can handle small currents well. There is an issue that cannot be resolved.

等の効果を奏する。As described above, the present invention introduces a pair of electrode rods into a vacuum container so that they can approach and separate from each other, and a cap-shaped disk-shaped structure comprising a contact part and an arc diffusion part at the inner end of each electrode rod. 'The electrodes are mechanically fixed, each of the electrodes and an electrode rod are arranged on the back of the electrode, and the current flowing through the electrode rod is changed to a loop current centered around the electrode rod to generate an axial magnetic field. In the vacuum interrupter which is electrically connected to each other by coils, the contact portion of the electrodes is formed of an Ou-Or-MO alloy having a low conductivity of 20 to 60, and the diffusion portion is formed of an Ou-Or-MO alloy having a low conductivity of 10 to 60. Since it is made of a material that has a conductivity of 20% and contains at least Ou, Fθ, and Or, it is possible to reduce the generation of eddy current, and there is no need to provide slits like in conventional books. This combination of the fact that the arc diffusion part is made of a material with high tensile strength, and that the mechanical strength of the entire electrode can be greatly improved. Furthermore, since the contact portion is made of an Ou-Or-Mo alloy, the dielectric strength can be greatly increased, and both large Ka and small currents can be effectively interrupted.

プタ。(1) In a vacuum vessel, a pair of ゛tun winds are relatively approached and separated from each other as fE (F), and a cap shape consisting of a contact part and an arc diffusion part at the inner end of the pole is ``4fTh''. A disc-shaped electrode is mechanically fixed, each of the above-mentioned 1 keyaki and electric rod are arranged on the back of the electrode, and the current flowing through the pole rod is changed to a loop current centered around the electrode rod. In the vacuum interrupter, each of which is electrically connected to a coil that generates an axial magnetic field, the electrode contact portion is formed of Ou-Or-Mo@gold having a low conductivity of 20-60. A vacuum interrupter, characterized in that the arc diffusion part is formed of a material having a conductivity of 0 to 20 cm and containing at least 40 u, Fe, and Or.
