IEEE C37.42-2016 IEEE Standard Specifications for High-Voltage (>1000 V) Fuses and Accessories

IEEE C37.42-2016 Стандарт IEEE спецификации для высокого напряжения (& Amp; GT; 1000) Предохранители и аксессуары

This standard establishes specifications for high-voltage (above 1000 V) fuses and accessories for use on ac electrical distribution systems. Devices with rated maximum voltages to 170 kV are covered. The devices to which this standard applies are as follows:a) Expulsion fuses (including fuse cutouts)b) Current-limiting fusesc) Items a) and b) used in fuse enclosure packagesd) Fuse supports of the type intended for use with fuses and fuse disconnecting switchese) Disconnecting devices (fuse disconnecting switches, disconnecting switches, and disconnecting cutouts) created by the use of a removable fuse unit or switch blade in a fuse supportf) Expulsion, current-limiting, and combination types of external capacitor fuses used with a capacitor unit, a group of units, or capacitor banks.g) Backup current-limiting fuses ("motor-starter fuses") used in conjunction with high-voltage motor startersh) Fuse links when used exclusively with expulsion fuses and fuse disconnecting switchesi) Items a) through f) having integral load-break meansj) Accessories including mounting brackets and switch stick (switch hooks)This standard may also be used for other devices that are similar to the devices listed in the scope.
