Abstract
The utility model provides a high-voltage fuse convenient to be exchanged, comprising a high-voltage fuse body and supporting ceramic bottles, wherein wiring terminal caps are arranged at two ends of the high-voltage fuse body; the wiring terminal caps are provided with binding posts, and two supporting ceramic bottles are arranged; a fixed clamping piece device is arranged at the upper end of one supporting ceramic bottle, and a retractable movable clamping device is arranged at the upper end of the other supporting ceramic bottle; the fixed clamping piece device is internally provided with wiring terminal cap inserting holes and binding post through holes; the inner diameter of each wiring terminal cap inserting hole is slightly more than the outer diameter of each wiring terminal cap; the retractable movable clamping device comprises a columnar outer sleeve with a hole sealing cover, and a movable end cover is arranged inside the other end of the columnar outer sleeve; the outer diameter of the movable end cover is less than the inner diameter of the columnar outer sleeve; and a spring is arranged between the sealing cover in the columnar outer sleeve and the movable end cover. According to the high-voltage fuse convenient to be exchanged, provided by the utility model, the high-voltage fuse can be rapidly processed after being fused, so that the processing time is greatly shortened after a PT (Platinum) high-voltage fuse is fused, and the processing time is reduced to about ten minutes from more than eighty minutes after the PT high-voltage fuse is fused; and therefore, the risk of exchanging the high-voltage fuse of a constructor is reduced, the power supply reliability is increased, and the high-voltage fuse is time-saving, labor-saving, convenient and fast.
Description
Technical field
The utility model belongs to the PT high pressure insurance technical field of transformer station, is specifically related to a kind of high-tension fuse of being convenient to change.
Background technology
The PT high pressure insurance of transformer station plays important protective effect, day-to-day operation to PT and whole power transformation system safety
In the work, often take place single-phasely with indirect arc ground connection, PT inside single-phase earthing or alternate is arranged indirectly because of ferro resonance, system
Short trouble, secondary loop short circuit and secondary side fuse do not fuse etc. and to cause PT high pressure fuse melting, are generally high-voltage fuse
Device fusing if fuse fails to obtain in time correctly, replacing fast, will make protection, metering etc. lose voltage, cause the loss that can't estimate.After the fuse blows of PT high pressure insurance, because fuse is firmly fixing by four screws, during replacing; Often four screw times spent on the degree of tightness fuse are too much; It is long make to change PT high pressure safe time, if the screw corrosion of fuse, then the processing time will be longer.But, the high pressure fuse melting, the corresponding bus lines secondary voltage breaks, and needs to use the secondary voltage of another section bus; If the processing time is long, have a strong impact on the reliability of power supply.
The utility model content
The purpose of the utility model is to overcome above-mentioned deficiency a kind of high-tension fuse that is convenient for changing is provided.
The purpose of this realization the utility model is through this realization of following technical scheme:
A kind of high-tension fuse that is convenient for changing comprises the high-tension fuse body and supports porcelain vase that said high-tension fuse body two ends are provided with the wiring end cap; The binding post that is provided with on the wiring end cap; Support that porcelain vase is two, one of them support porcelain vase upper end is provided with clamping and decides the folder device, and another supports the upper end of porcelain vase to be provided with telescopic movable clamping device; Wiring end cap patchhole and binding post through hole are set in the fixed clip device; The internal orifice dimension of wiring end cap patchhole is slightly larger than the external diameter of wiring end cap, and telescopic movable clamping device includes the cylindricality overcoat of capping with holes, is provided with movable end cover in the other end of cylindricality overcoat; The external diameter of movable end cover is provided with spring between capping and the movable end cover less than the internal diameter of cylindricality overcoat in the cylindricality overcoat.
The above-mentioned high-tension fuse that is convenient for changing, the outside of said movable clamping device and fixed clamp device is provided with lead-in wire.
Adopt technique scheme; The utility model has following advantage: the utility model has changed one of former cause and has supported on the porcelain vase method with the bolt high-tension fuse; At first with an end insertion activity clamping device of high-tension fuse, a little firmly push high-tension fuse left when needing to change, whole like this high-tension fuse height can be moved to the left; The convenient other end with high-tension fuse is inserted in the fixed clamp device; Owing to be provided with spring in the movable clamping device, lean on the elastic force of spring conveniently to install, and rear spring is installed resets and make high-tension fuse be clamped at two to support in the porcelain vases; An amount high-tension fuse damages simultaneously, also can take off the high-tension fuse of damage easily and fast.When the utility model is installed high-tension fuse, need not re-use bolt, when dismantling behind the high pressure fuse melting; Need not become flexible screw again, shorten the time of dismounting high-tension fuse greatly, like this; When changing high-tension fuse, do not need again elasticity bolt and labor time, energy.Lead-in wire is fixed on the clamping device simultaneously, has also shortened the maintenance time behind the high pressure fuse melting greatly.The utility model can be realized high-tension fuse fusing back fast processing; Greatly reduce the processing time behind the PT high pressure fuse melting; Success was reduced to the processing time behind the PT high pressure fuse melting about ten minutes from more than 80 minutes; Reduce the workmen and changed the high pressure risk for insurance, increased power supply reliability, time saving and energy saving, convenient and swift.
