摘要： According to the present invention an electrical contact (1) is provided, which is cheap, has an excellent workability and maintains the effect of chopping current reduction. The electrical contact comprises a Cu matrix, and compounds Cu and low melting point metal which are dispersed in the Cu matrix, wherein the vapor pressure of the low melting point metal is more than 10 5 Pa at 1000 °C, the compound has a stoichiometric ratio which is the value of the low melting metal / Cu which is greater than 0.5, and the longitudinal direction of the compound is oriented at an angle of 90 ° ± 10 ° to the contact surfaces. The method of manufacturing the electrical contact comprises the steps of stretching the mixture of the Cu matrix with the compounds by 70-85% while heating, using the surfaces of the electrical contact as a contact.

摘要： An electromagnetic operation device, comprising electromagnetic operators 4 each paired with a vacuum valve 1 of each phase of three phases, is equipped with main shafts 2 that can operate independently for each phase and a three-phase connecting shaft 3 that synchronizes the operation of the three phases in accordance with the operation of each main shaft. The rod 44 of the electromagnetic operator 4 is connected with the blade 45 of the main shaft 2 at the fulcrum 46 and the blade 47 of the three-phase connecting shaft 3 is connected with the blade 45 of the main shaft 2 by the linkage 7. The motion of a main shaft 2 that has operated quicker than the others is transmitted to the other main shafts via the three-phase connecting shaft 3 so as to synchronize the operation of the three phases.
