Abstract
A space-saving composite cross arm falling type fuse with good usage effect comprises a composite cross arm insulator. A wiring terminal is designed on the composite insulator; the end of the composite cross arm insulator is fixedly connected with a bracket; the left end of the bracket is fixedly connected with an insulator, and the right end of the bracket is fixedly connected with an upper contact; the lower end of the insulator is fixedly connected with a lower wiring terminal; the lower wiring terminal is connected with a lower contact; the lower contact is fixedly connected with a fuse tube; the fuse tube is provided with a fuse; the fuse is connected with the lower contact; the upper part of the fuse tube is fixed with an operating ring; and the upper end of the fuse tube is corresponding to the upper contact.
Description
Technical field
The utility model relates to a kind of fuse, relates in particular to a kind of compound cross-arm fuse switch.
Background technology
Fuse switch is one of main protection of power equipment; be installed on the cross-arm on the shaft tower; this mounting means lead-in wire is more; need to install separately with cross-arm; take the vertical space of shaft tower; set-up time is longer, and the activity space of maintainer on shaft tower reduces relatively greatly, strengthened difficulty of construction.
Summary of the invention
The purpose of this utility model provides a kind ofly can save space, compound cross-arm fuse switch that result of use is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of compound cross-arm fuse switch, comprise composite cross-arm insulator, be designed with upper connecting terminal on the composite cross-arm insulator, it is characterized in that: the end of composite cross-arm insulator is fixedly connected with support, the left end of support is fixedly connected with insulator, the right-hand member of support is fixedly connected with upper contact head, the lower end of insulator is fixedly connected with lower connecting terminal, is connected with lower contact on the lower connecting terminal, is fixedly connected with cartridge fuse on the lower contact, fuse is housed in the cartridge fuse, fuse is connected with lower contact, and the top of cartridge fuse is fixed with the operation ring, and the upper end of cartridge fuse is corresponding with upper contact head.
The utility model has the advantages of and be: because this structure of the present utility model is installed fuse switch and composite cross-arm insulator combination, so use the utility model cartridge fuse and horizontal plane have 35
OAbout angle, more convenient operation; So saved the fixedly cross-arm of fuse switch, reduced connecting lead wire, man-hour has been saved in the i.e. installation of fuse switch in the time of the cross-arm installation.

Fig. 2 is another kind of structural representation of the present utility model.
In the accompanying drawing: 1, upper connecting terminal; 2, compound horizontal dawn insulator; 3, support; 4, upper contact head; 5, operation ring; 6, fuse; 7, cartridge fuse; 8, lower contact; 9, lower connecting terminal; 10, insulator.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
The utility model such as Fig. 1, shown in 2, a kind of compound cross-arm fuse switch, comprise composite cross-arm insulator 2, be designed with upper connecting terminal 1 on the composite cross-arm insulator 2, it is characterized in that: the end of composite cross-arm insulator 2 is fixedly connected with support 3, the left end of support 3 is fixedly connected with insulator 10, the right-hand member of support 3 is fixedly connected with upper contact head 4, the lower end of insulator 10 is fixedly connected with lower connecting terminal 9, is connected with lower contact 8 on the lower connecting terminal 9, is fixedly connected with cartridge fuse 7 on the lower contact 8, fuse 6 is housed in the cartridge fuse 7, fuse 6 is connected with lower contact 8, and the top of cartridge fuse 7 is fixed with operation ring 5, and the upper end of cartridge fuse 7 is corresponding with upper contact head 4.
To be installed on the shaft tower with the compound cross-arm of fuse switch, wire is placed on the cross-arm, uses the upper connecting terminal fixing cord, and the wire that needs T to connect is connected on the lower connecting terminal, loads onto cartridge fuse and gets final product.
