Abstract
The invention belongs to the field of electric and provides a high-voltage fuse convenient for changing a fusant. The high-voltage fuse comprises a porcelain tube and the fusant, wherein end covers are arranged on the two ends of the porcelain tube, and connection parts of a power supply are arranged on the end covers; the fusant is arranged in the porcelain tube, a fuse wire is arranged in the fusant, contacts are arranged at the two ends of the fusant, the fusant is mounted and sealed in the porcelain tube, and the contacts at the two ends of the fusant are in electric contact with the end covers; a circular opening is formed in the end part of one of the end covers, and a cover plate is articulated on the end cover with the circular opening and can be closed to cover the opening; the fusant can be taken out through the opening after the cover plate is opened; a clamp connecting the end cover and the cover plate is arranged on the side surface of the end cover and the side surface of the cover plate; the opening can be opened or closed after the clamp is moved; a sealing gasket is also arranged between the end cover and the cover plate; a spring is arranged in the other end cover and props against the fusant. Therefore, the high-voltage fuse has the advantages of convenience and quickness in fusant change.
Description
Technical field
The invention belongs to technical field of electricity, concretely relate to fuse.
Background technology
Fuse includes that porcelain tube, porcelain tube two ends have end cap, and end cap has the connecting portion of power supply；Have molten in porcelain tube
Body, has fuse, melt two ends to have contact in melt.
In using, melt is arranged in porcelain tube and seals, the contact at melt two ends and end cap electrical contact, after fuse failure just
Melt to be changed.
In prior art, the end cap at two ends uses screw to be connected on porcelain tube, so will be by end cap during replacing melt
Screw unload, the shortcoming there is troublesome poeration, wasting time.
Summary of the invention
The shortcoming that the purpose of the present invention is aiming at prior art, it is provided that a kind of replacing melt high-voltage fuse easily and efficiently
Disconnected a kind of high-tension fuse being conveniently replaceable melt of device.
The technical scheme is that and be achieved in that: a kind of high-tension fuse being conveniently replaceable melt, including porcelain tube, porcelain
Pipe two ends have end cap, and end cap has the connecting portion of power supply；In porcelain tube, there is melt, in melt, have fuse, melt two ends
Having contact, melt is arranged in porcelain tube and seals, the contact at melt two ends and end cap electrical contact；It is characterized in that: one of them
End cap end has the opening of circle, and also plate lid is hinged on end cap, and plate is closed can be covered with opening, and cover plate is opened, melt
Can remove from opening part, also have in end cap and cover plate side and connect end cap and the buckle of cover plate, pull buckle, can open or
Close opening, between end cap and cover plate, also have sealing gasket.
Saying also have spring inside another end cap further, spring heads on melt.
Say further, the internal tooth-shape structure also with melt outer lower side with cooperation of described porcelain tube.
The invention has the beneficial effects as follows: such high-tension fuse has replacing melt advantage easily and efficiently；At another
Also having spring inside individual end cap, spring heads on melt, also has the advantage facilitating removal of melt；Described porcelain tube inside and melt
Outer lower side also has the tooth-shape structure of cooperation, also has the advantage preventing melt from sliding out quickly, causing the accident.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of breaker of the present invention.
Wherein: 1, porcelain tube 2, end cap 3, the connecting portion 4 of power supply, melt 5, fuse 6, contact 7, opening
8, buckle 9, sealing gasket 10, hinge 11, spring 12, tooth-shape structure 13, cover plate.
Detailed description of the invention
The present invention is described further below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of high-tension fuse being conveniently replaceable melt, including porcelain tube 1, porcelain tube two ends have end cap 2, end
Cover the connecting portion 3 with power supply；In porcelain tube, there is melt 4, in melt, have fuse 5, melt two ends to have contact 6, melt
Being arranged in porcelain tube and seal, the contact at melt two ends contacts with end cap；It is characterized in that: one of them end cap end has circle
Opening 7, also cover plate 13 is hinged on end cap, cover plate close can be covered with opening, cover plate is opened, and melt can be from opening part
Removal, also has at end cap and end cap sidewall and connects end cap and the buckle 8 of cover plate, pull buckle, can open or close opening,
Sealing gasket 9 is also had between end cap and cover plate.
In figure, 10 is the hinge of hinged place, and described buckle is the buckle of prior art.Such a people operation is the most permissible
Changing rapidly melt, it is achieved the purpose of the present invention, in figure, A, B, C direction is the order opened.
Saying also have spring 11 inside another end cap further, spring heads on melt, and so opening rear melt will
Expose opening one section, it is simple to take out melt.
Say further, the internal tooth-shape structure 12 also with melt outer lower side with cooperation of described porcelain tube.So exist
The melt in a flash opened the most out will not reduce melt speed out, try to avert accidents.
The foregoing is only the specific embodiment of the present invention, but the architectural feature of the present invention is not limited to this, any ability
The technical staff in territory is in the field of the invention, and change or the modification made all are contained in the scope of the claims of the present invention.
