Description
Technical field
The utility model belongs to fuse technologies field, is specifically related to oil immersed type gamut protection high-voltage and current-limitation fuse with signalling device.
Technical background
Fuse is a kind of overcurrent or short circuit current protector.Fuse is primarily of melt and the part such as fusion tube and arc-extinguishing medium composition.During use, be series at by fuse in protected circuit, when the electric current of protected circuit exceedes setting, and after certain hour, the heat fusing melt produced by melt self, makes circuit disconnect, thus plays the effect of protection.The electrical equipment of deenergizing is divided using metallic conductor as melt; be series in circuit; when transshipping or short circuit current passes through melt, heating self fuses by melt, thus all serves certain protective effect to electric power system, various electrical equipment and household electrical appliance.Have inverse time lag characteristic, when overload current hour, fusing time is long; When overload current is large, fusing time is short.
Based on this, fuse is widely used in power industry, and common fuse kind is a lot; and fuse is inserted for oil immersed type gamut, it can produce sleeve leakage of oil at work usually; the accidents such as fuse can not normally fuse, explosion, cause larger economic loss.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of insulation property can ensure new type fuse completely; Avoid and solve oil immersed type gamut protection fuse completely and cause problem in the pollution of transformer oil, sealing at sleeve oil impregnate or fusing explosion; Solve oil immersed type gamut and insert fuse point cantact, the problem causing long-play heating of contact to cause fuse contact part to burn.
Be specially: oil immersed type gamut protection high-voltage and current-limitation fuse with signalling device; this fuse comprises fuse member; this fuse member is provided with the first coil component spring fingertip, the second coil component spring fingertip and high temperature protection striker; described high temperature protection striker is connected with the second pull bar side with two the first pull bars arranged side by side; the opposite side of the first pull bar and the second pull bar has a far-end of extension; this far-end is provided with handle; it is characterized in that; described fuse member is outside equipped with outer tube; outer tube contains screen, middle conducting ring.
Preferably, described first coil component spring fingertip place, is provided with middle conducting ring, has middle hermetically-sealed construction to seal thereon in outer tube;
Preferably, described outer tube has rear end cap, and rear end cap contains the hermetically-sealed construction of hermetically sealed case pipe;
Preferably, one end of described first pull bar and the nearly handle of the second pull bar is provided with ring flange, has ring flange sealing gasket, hermetically sealed case pipe;
Preferably, handle becomes radius arc section with one section.
The beneficial effects of the utility model are:
1, integral type outer tube, ring flange, middle contact screw, the position limiting sealed design of rear end cap, thoroughly solves oil leak problem in the past; 2, silicon rubber double pull rod structure design, solve in the past band signal transfer device time withstand voltage inadequate problem; 3, spring touch finger, middle conducting ring, rear end cover structure designs, and solves bad problem of in the past conducting electricity; 4, fuse member structural design, solves fusion tube in the past overheated, installs inconvenience, conducts electricity bad problem; The problems such as 5, this product handle place becomes radius arc design, solves to install when changing fuse member to require great effort in the past, inconvenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model fuse;
Embodiment
