    • A pair of main electrodes are airtightly attached to their corresponding end openings of an insulating cylinder so that their discharge surfaces are opposed to each other with a gap between them in the insulating cylinder. An intermediate electrode is airtightly attached to the central portion of the insulating cylinder so that its discharge surface coaxially surrounds the space between the discharge surfaces of the main electrodes and faces the lateral faces of the main electrodes to define the discharge gaps. Electrode activators are contained in cavities or grooves in or on the main electrodes so as to be isolated from the discharge surfaces thereof, or are arranged on one of the respective discharge surfaces of the main and intermediate electrodes. When the arrester performs a continuous discharging operation, the electrodes without electrode activators thereon are melted by the heat generated by a discharged current, thereby short-circuiting the main and intermediate electrodes to establish an electrode short-circuit mode. Thus, open breakage, attributed to the burning of the arrester and its holder, may be avoided.
    • 一对主电极气密地连接到绝缘筒的相应的端部开口,使得它们的排出表面在绝缘筒中彼此相对并且间隔开。 中间电极气密地连接到绝缘筒的中心部分,使得其排出表面同轴地围绕主电极的放电表面之间的空间并面对主电极的侧面以限定放电间隙。 电极激活剂被包含在主电极中或其上的腔或槽中,以便与其排出表面隔离,或者设置在主电极和中间电极的各个放电表面中的一个上。 当避雷器执行连续放电操作时,其上没有电极激活器的电极被由放电电流产生的热量熔化,从而短路主电极和中间电极以建立电极短路模式。 因此,可以避免由于避雷器及其保持器的燃烧导致的断路。

    • In a surge protection device 40 (40-1 or 40-2) used for a surge protection apparatus, a gas arrester 41 is connected in series with a varister group consisting of a plurality of varisters 42-1 to 42-5 which have high withstand capacity and are connected in parallel to one another and a discharge resistor 43 is connected between both electrodes of the varister group. Besides, since the varister voltages are set higher than the peak value of the AC power supply voltage, the varisters 42-1 to 42-5 are normally insulated from a power supply circuit by the gas arrester 41. Even if an abnormal voltage is applied, since an operating voltage of the varisters 42-1 to 42-5 is set higher than a peak value of the AC power supply voltage, AC power supply current will not flow. Charges stored in the varisters 42-1 to 42-5 are released quickly through the resistor 43, making it possible to prevent the gas arrester 41 from restriking. This provides a small, reliable, inexpensive surge protection device (SPD) relatively simple in structure and a surge protection apparatus using thereof.
    • 在用于浪涌保护装置的浪涌保护装置40(40-1或40-2)中,气体避雷器41与由多个具有高电平的多个清洗剂42-1至42-5组成的清漆组串联连接 承受能力并且彼此并联连接,并且放电电阻器43连接在所述清漆组的两个电极之间。 此外,由于将修整电压设定为高于交流电源电压的峰值,所以通过避雷器41将整流器42-1至42-5通常与电源电路绝缘。即使施加了异常电压 由于调光器42-1至42-5的工作电压被设定为高于交流电源电压的峰值,所以交流电源电流不会流动。 存储在调光器42-1至42-5中的电荷通过电阻器43快速释放,使得可以防止气体避雷器41再起弧。 这提供了一种结构相对简单且使用其的浪涌保护装置的小型,可靠,廉价的浪涌保护装置(SPD)。

The fine particle of highly pure magnesium oxide increases the number of nuclei in a melt, and as a result thereof, increases the graphite spheroid count of a spheroidal graphite cast iron being produced. Another additive for use in producing spheroidal graphite cast iron of the present invention contains at least one selected from the group consisting of a graphite-spheroidizing material, an inoculant and a graphite-spheroidizing inoculant, and an oxide of a metal which has, at a temperature of a melt at a time when subjected to a graphite-spheroidizing treatment, an affinity for oxygen smaller than that of a graphite-spheroidizing element being used in the graphite-spheroidizing treatment. By adding to the melt the metal oxide which oxidizes the graphite-spheroidizing element in the melt to an oxide thereof, a great number of fine oxide particles of the graphite-spheroidizing element is dispersed in the melt to provide a spheroidal graphite cast iron having a great number of fine graphite spheroids and a small chill area ratio.
