The purpose of this utility model is a kind of multi-functional insulator of design, has switch and lightning-arrest and over-voltage protecting function, abbreviates lightning arrester with combined jet fuse switch as.
The purpose of this utility model is achieved in that the insulator to expulsion fuse carries out architecture advances.This lightning arrester with combined jet fuse switch, comprise the cartridge that powers on, full skirt group, bottom electrode head, terminal block, drop switch, double-deck arc-extinguishing tube and fusible link, wherein form multiple tube parts by upper contact head, double-deck arc-extinguishing tube, fusible link and following contact and drop switch, it is characterized in that also having additional insulating sleeve and toroidal rheostat, wherein the insulating sleeve middle part is provided with a snap ring, also be provided with the installation handle on the snap ring, the handle outside be installed be surrounded by insulating barrier; Toroidal rheostat is placed on outside the insulating sleeve, and its skin is being surrounded by insulating barrier, and with flange locking, outside mold pressing silica gel full skirt group constitutes one; The multiple tube parts insert in the magnetic substance full skirt group, and its upper contact head joins with the cartridge that powers on, and following contact and bottom electrode head join; Terminal block is arranged on the first side of bottom electrode: the cartridge that powers on adopts band mesopore electrode tip or enclosed type electric cartridge.
This lightning arrester with combined jet fuse switch has kept the shape of former expulsion fuse, has put into the ring-type variable resistor in the Lower Half (or first half) of insulating sleeve and has reached purpose lightning-arrest and overvoltage protection; Be provided with a snap ring at the insulating sleeve middle part, also be provided with the installation handle on the snap ring, make installation more convenient.
This lightning arrester with combined jet fuse switch has kept the function of three kinds of electrical equipment, and three kinds of electrical equipment are combined together, and on RW3-11 series drop switch, protection equipment runs well, and is current desirable regeneration product.
The present invention is further described below in conjunction with embodiment and accompanying drawing.
