Abstract
The invention discloses a fuse. One end of each of two pulling rods of the fuse is connected to a fixed plate respectively to form a V shaped structure, and the other end of each of the two pulling rods of the fuse is connected to two ends of a fuse tube respectively through a current conducting plate and a pillar. The fuse is characterized in that: an upper end of the fuse tube is tightly pressed in a contact point baffle plate through an upper spring, and one side of the fuse tube close to the upper spring is provided with a side contact which is in electrical contact with a draw ring. According to the fuse, a single contact connection mode, an upper static contact compound structure and a fusion tube contact plug connecting method of an outdoor drop type fuse are changed, and the fuse has the characteristics of non-combustible arc of fault current connection contact, short segmentation time and the like and has windproof and loosing prevention functions.
Description
Technical field
The present invention relates to a kind of fuse, belong to the technical field of circuit emergency protective device.
Background technology
Isolating switch+fuse combination is an outdoor high-voltage protection electrical equipment; Have to fall and cut-off function; It is the advanced product that specialty replaces the old type tube fuse switch; Be fit to wind energy turbine set and the power station essential product as the protection segmentation, it is assemblied on distribution transformer high-pressure side or the distribution wire service main road, the usefulness of transmission line, power transformer overload and short-circuit protection and deciliter rated load electric current.Have simple to operate, easy to maintenance.Effectively solving fault-free falls.Yet factors such as fault-free is fallen, fluctuation of service that the fuse of prior art exists can not satisfy people's demand.
Summary of the invention
The object of the present invention is to provide a kind of fuse, have multipoint mode contact function, be fit to current electrical network needs.
The present invention adopts following technical scheme to realize:
A kind of fuse; Two leading-drawing rod one ends of this fuse are connected to and form V font structure on the fixed head; The other end is connected the two ends of fuse tube respectively through conductive plate and pillar; It is characterized in that the upper end of said fuse tube is pressed in the contact point baffle plate through upper spring, the side near said upper spring of fuse tube is provided with and the electric side contact that contacts of draw ring.
Fuse of the present invention has changed outdoor drop-out type fuse list contact connection mode; Upper static contact contact composite structure; Fusion tube contact socket connection method has not characteristics such as arcing, split time weak point of fault current connection contact, and has windproof, locking functions.
Description of drawings
Fig. 1 is the structural representation of fuse of the present invention.
Embodiment
Through facing the description of embodiment down; To help public understanding the present invention more; But can't be regarded as restriction by the concrete embodiment that the applicant is given to technical scheme of the present invention, any definition to parts or technical characterictic change and/or to overall structure do form but not the conversion of essence all should be regarded as the protection range that technical scheme of the present invention limits.
As shown in Figure 1; Leading-drawing rod 1 and leading-drawing rod 2 are connected to the both sides of fixed head 3; Form V font structure, the other end is connected the two ends of fuse tube 4 respectively through conductive plate and pillar, and the upper end of fuse tube is pressed in the contact point baffle plate 6 through upper spring 5; One side of fuse tube 2 is provided with side contact 7, side contact 7 and draw ring 8 electric contacts.When system broke down, fault current made the fuse quick-break, and formed electric arc, and expulsion tube receives electric arc scorching hot, decomposited a large amount of gas and made formation high pressure in the pipe, and form vertical blowing along pipeline, and electric arc is elongated rapidly and extinguishes.Change with insulating bar last first moving contact of leaving behind like need, take off fuse tube 4 simultaneously, the installation fuse.Auxiliary contact also separates, and between auxiliary contact, produces electric arc, and electric arc is elongated in the arc-extinguish chamber slit, produces gas simultaneously, when current over-zero, with arc extinction.When the needs disjunction, draw back draw ring 8 with insulating bar, visible obviously fracture makes things convenient for repair and maintenance.
Certainly; The present invention can also have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
