Abstract
A composite cross arm drop-out fuse capable of saving space and good in use effect comprises a composite cross arm insulator, an upper terminal block is designed on the composite cross arm insulator of which the end part is fixedly connected with a support, the left end of the support is fixedly connected with an insulator, the right end of the support fixedly connected with an upper contact, the lower end of the insulator is fixedly connected with a lower terminal bock connected with a lower contact, the lower contact is fixedly connected with a fuse pipe internally provided with a fuse, and the fuse is connected with the lower contact; and an operation ring is fixed on the upper part of the fuse pipe of which the upper end corresponds to the upper contact.
Description
Technical field
The present invention relates to a kind of fuse, relate 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 invention is to provide and 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 used in the present invention is: a kind of compound cross-arm fuse switch, comprise compound cross arm insulator, design has upper connecting terminal on the compound cross arm insulator, it is characterized in that: the end of compound 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 down contact on the lower connecting terminal, is fixedly connected with cartridge fuse on the following contact, fuse is housed in the cartridge fuse, fuse is connected with following contact, and the operation ring is fixedly arranged at the top of cartridge fuse, and the upper end of cartridge fuse is corresponding with upper contact head.
Advantageous effect of the present invention is: because this structure of the present invention is installed fuse switch and the combination of compound cross arm insulator, so use cartridge fuse of the present invention and horizontal plane have 35
OAbout angle, more convenient operation; So saved the fixedly cross-arm of fuse switch, reduced to connect going between, man-hour has been saved in the i.e. installation of fuse switch in the time of the cross-arm installation.

Fig. 1 is structural representation of the present invention;
Fig. 2 is another kind of structural representation of the present invention.
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, following contact; 9, lower connecting terminal; 10, insulator.
Embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
The present invention such as Fig. 1, shown in 2, a kind of compound cross-arm fuse switch, comprise compound cross arm insulator 2, design has upper connecting terminal 1 on the compound cross arm insulator 2, it is characterized in that: the end of compound 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 down contact 8 on the lower connecting terminal 9, is fixedly connected with cartridge fuse 7 on the following contact 8, fuse 6 is housed in the cartridge fuse 7, fuse 6 is connected with following contact 8, and operation ring 5 is fixedly arranged at the top of cartridge fuse 7, and the upper end of cartridge fuse 7 is corresponding with upper contact head 4.
The compound cross-arm that will have fuse switch is installed on the shaft tower, and lead is placed on the cross-arm, uses the upper connecting terminal fixing cord, and the lead that needs T to connect is connected on the lower connecting terminal, loads onto cartridge fuse and gets final product.
