Abstract
An object of the utility model is to provide a drop-out fuse. The drop-out fuse comprises an insulator and a fuse tube. A fixing device is disposed on a support arm extending out of the upper part of the insulator; the upper part of the fuse tube is provided with bronze castings and a pull ring, and the top end of the bronze castings is connected with the support arm extending out of the upper part of the insulator; the lower part of the fuse tube is provided with bronze castings, the right side of the bronze castings are provided with a hinge bolt, and the hinge bolt is connected with a support arm extending out of the lower part of the insulator; and the other ends of the bronze castings at the upper and lower parts of the fuse tube are provided with stainless steel springs. Through high-quality design of all parts of the drop-out fuse, the drop-out fuse has good product weatherability, the good conductivity fault connection and disconnect ability and the good load connection and disconnection ability, and the drop-out fuse has more safety guarantees during using.
Description
Technical field
The utility model relates to power and distribution supply cable and power trans-former protection equipment 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 and carry out equipment throwing, cut operation.Current fuse switch is second-rate, and Product Process is coarse, can cause so a lot of hidden dangers, therefore designs a kind of fuse switch and addresses these problems just very necessary.
Utility model content
The utility model provides a kind of fuse switch, and by adopting high-quality part, thereby excellent design overcomes the problem existing in background technology.
The purpose of this utility model is to provide a kind of fuse switch, comprises insulator, and cartridge fuse has fixture on the support arm that stretch out described insulator top; Described cartridge fuse top is provided with bronze casting and draw ring, and bronze casting top is connected with the support arm that stretch out insulator top; Described cartridge fuse below is provided with bronze casting, and bronze casting right side arranges hinged bolt, and hinge bolt is connected with the support arm that stretch out insulator below; Described cartridge fuse upper and lower bronze casting other end is provided with stainless steel spring.
Further improve and be: described fixture right side is provided with terminal, on terminal and hinge bolt right side is provided with copper current path.
Further improve and be: described draw ring top is provided with load and cut-offs hook.
Further improve and be: on the support arm that stretch out on described hinge bolt and insulator top, be provided with silver to silver contact.
The beneficial effects of the utility model: by the design to fuse switch each several part high-quality, make product weatherability, water conservancy diversion failure on-off ability, load connecting-disconnecting function better, more there is safety guarantee in the process of using.
