Abstract
The utility model provides a novel 35kV fall -off switch fuse, the port of working a telephone switchboard on, that connects including the T type, go up the conductor, the fuse, the insulated wire, work a telephone switchboard down port and conductor down, the sub -unit connection that connects of T type the conductor, insulated wire and fuse setting at work a telephone switchboard under with the intermediate position of port of the last port of working a telephone switchboard, the lower part of last conductor set up the port of working a telephone switchboard, the upper portion of lower conductor be provided with down the port of working a telephone switchboard. The utility model discloses the insulated wire setting is at last intermediate position of working a telephone switchboard the port and the port of working a telephone switchboard down, can be in the operation can borne tension force, prevent to be broken by the fuse saving cost, easy maintenance.
Description
Technical field
This utility model belongs to power industry power transmission and transformation equipment technical field, particularly relates to a kind of novel 35kV drop switch fuse.
Background technology
At present, when transformer station's imperial examination held in spring or line outage repair apparatus, can frequent change used be operated.Fuse is the 35kV electric fuse (identical with electric fuse principle) become within drop switch used, according to the payload that station becomes, selects the fuse of different rated current.Fuse is a kind of when change institute used on-load is more than the rated current of fuse, will fuse, in order to protect the equipment of transformator.The pulling force that existing 35kV drop switch fuse also exists bearing is only small, operates and unskilled very easily fuse is broken, and human weld can cause again rated current to change, it is impossible to the correct problem protecting transformator.
Utility model content
This utility model provides a kind of cost cheap for solving the technical problem of existence in known technology, it is prevented that the novel 35kV drop switch fuse being pulled off.
This utility model is adopted the technical scheme that by the technical problem solving to exist in known technology: a kind of novel 35kV drop switch fuse includes T connector, upper conductor, upper Wiring port, fuse, covered wire, lower Wiring port and lower conductor, the bottom of described T connector is connected to upper conductor；Described covered wire and fuse are arranged on Wiring port and the centre position of lower Wiring port；The bottom of described upper conductor arranges Wiring port；The top of described lower conductor is provided with lower Wiring port.
This utility model can also adopt following technical measures.
Described covered wire is specifically arranged on the bottom of fuse, and the length of described covered wire, less than the length of fuse, is conducive to bearing in operation pulling force, it is prevented that broken by fuse, saves cost, easy to maintenance.
Described covered wire specifically adopts rubber conductor or polyvinyl chloride insulation wire, is conducive to easy to use, and cost is cheap.
This utility model has the advantage that and has the benefit effect that owing to this utility model covered wire is specifically arranged on the bottom of fuse, can bear pulling force in operation, it is prevented that broken by fuse, saves cost, easy to maintenance；Described covered wire adopts rubber conductor or polyvinyl chloride insulation wire, is conducive to easy to use, and cost is cheap.
Accompanying drawing explanation
Fig. 1 is the structural representation that this utility model embodiment provides.
In figure:
1-T type joint；2-upper conductor；The upper Wiring port of 3-；4-fuse；5-covered wire；Wiring port under 6-；7-lower conductor.
Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and it be as follows to coordinate accompanying drawing to describe in detail:
Refer to Fig. 1:
This utility model provides a kind of novel 35kV drop switch fuse, and including T connector 1, upper conductor 2, upper Wiring port 3, fuse 4, covered wire 5, lower Wiring port 6 and lower conductor 7, the bottom of described T connector 1 is connected to upper conductor 2；Described covered wire 5 and fuse 4 are arranged on Wiring port 3 and the centre position of lower Wiring port 6；The bottom of described upper conductor 2 arranges Wiring port 3；The top of described lower conductor 7 is provided with lower Wiring port 6.
Described covered wire 5 is specifically arranged on the bottom of fuse 4, and the length of described covered wire 5, less than the length of fuse 4, is conducive to bearing in operation pulling force, it is prevented that broken by fuse 4, saves cost, easy to maintenance.
Described covered wire 5 specifically adopts rubber conductor or polyvinyl chloride insulation wire, is conducive to easy to use, and cost is cheap.
Operation principle
Covered wire 5 of the present utility model is specifically arranged on the bottom of fuse 4, and when circuit for generating fault blows fuse 4 time, the covered wire 5 of fuse 4 bottom can be used to the pulling force bearing in operating process, it is simple to work about electric power personnel overhaul.
Utilize technical scheme described in the utility model, or those skilled in the art is under the inspiration of technical solutions of the utility model, design similar technical scheme, and reach above-mentioned technique effect, all fall into protection domain of the present utility model.
