Abstract
The object of this invention is to provide a kind of fuse switch and comprise insulator, cartridge fuse, the support arm stretched out above described insulator has fixture; Be provided with bronze casting and draw ring above described cartridge fuse, bronze casting top is connected with the support arm stretched out above insulator; Be provided with bronze casting below described cartridge fuse, arrange hinged bolt on the right side of bronze casting, hinge bolt is connected with the support arm stretched out below insulator; Described cartridge fuse upper and lower bronze casting other end is provided with stainless steel spring.By the design to fuse switch each several part high-quality, make product weatherability, flow conductivity failure on-off ability, load connecting-disconnecting function better, in the process used, more there is safety guarantee.
Description
Technical field
The present invention relates to power and distribution supply cable and protection equipment for power transformer in a kind of electric power system, especially a kind of fuse switch.
Background technology
Fuse switch is the most frequently used a kind of protective switch of the short circuit of 10kV distribution line branch line and distribution transformer; it have economy, easy to operate, adapt to the features such as outdoor environment is strong, be widely used in 10kV distribution line and distribution transformer primary side as protection with carry out equipment throwing, cut operation.Current fuse switch is second-rate, and Product Process is coarse, can cause a lot of hidden danger like this, therefore designs a kind of fuse switch and addresses these problems just very necessary.
Summary of the invention
The invention provides a kind of fuse switch, by adopting high-quality part, excellent design thus overcome Problems existing in background technology.
The object of this invention is to provide a kind of fuse switch, comprise insulator, cartridge fuse, the support arm stretched out above described insulator has fixture; Be provided with bronze casting and draw ring above described cartridge fuse, bronze casting top is connected with the support arm stretched out above insulator; Be provided with bronze casting below described cartridge fuse, arrange hinged bolt on the right side of bronze casting, hinge bolt is connected with the support arm stretched out below insulator; Described cartridge fuse upper and lower bronze casting other end is provided with stainless steel spring.
Further improvement is: be provided with terminal on the right side of described fixture, is provided with copper current path on terminal and on the right side of hinge bolt.
Further improvement is: be provided with load above described draw ring and cut-off hook.
Further improvement is: be provided with silver on described hinge bolt and on the support arm stretched out above insulator to silver contact.
Beneficial effect of the present invention: by the design to fuse switch each several part high-quality, makes product weatherability, flow conductivity failure on-off ability, load connecting-disconnecting function better, in the process used, more has safety guarantee.
