Description
Technical field
The utility model relates to a kind of hv cable termination, relates in particular to a kind of 66kV of being applicable to and above prefabricated hv cable termination.
Background technology:
At present, 66kV and above hv cable termination on the international market, dry insulation electric capacity shape structure commonly, oil-filled or not oil-filled stress cone type structure.Several structures all have shortcoming separately.
The stress cone type cable termination of oil-filled porcelain overcoat is the longest service time, and the consumption and the market share are also maximum at present.This terminal is with after the cable end preliminary treatment, and stress cone is sleeved in the cable body insulation, and the stress cone screen is communicated with cable insulation screen outward, insulator is sleeved on outside it, cable is led core and is communicated with jointing clamp, fills insulating material between the insulation of insulator and cable body, as silicone oil etc.For insulator, also useful epoxy tube substitutes now, and epoxy tube is outward the silicon rubber full skirt.
It is very high when the cable termination of this structure is installed at the scene for the pretreated technological requirement of cable body insulated part, and belong to oil-filled equipment, its operation and maintenance are also pretty troublesome, do not meet the no oiling development trend of high-tension apparatus yet, and it is relatively heavier, mounting means is dumb, installs also inconvenient.But its application time is very long, and because adopt the cause of insulator or epoxy tube, its mechanical strength is very high.
The nearest dry type silicone rubber for cable terminal of the 110kV that occurs, in fact still the stress cone structure that adopts is formed by three sections mostly, first suit after the cable preliminary treatment, or suit stress cone after the pre-expansion, then suit top is two sections, and is main with out of doors or on the indoor terminal.
Its advantage is light and handy, and mounting means is flexible, and is easy for installation.But because these several sections all made by silastic material, so its mechanical strength is very low; And also be very high for the pretreated technological requirement in cable body insulation position, otherwise break down easily; In addition, each intersegmental moisture seal also is that requirement is very high, and especially cable termination is when the effect of the various power of long-time running issues the distortion of biology reason; Also have, physical deformation when taking place in the cable termination of this structure, and it also is a very acid test that the faying face of terminal and cable body can or can not go wrong.
Also have a kind of not oil-filled condenser type cable termination structure, on market, move for many years, also very popular with users.This terminal is a coiling condenser type insulation system in cable body insulation, protect as sheath with heat-shrink tube, outside suit silicon rubber full skirt.The cable termination of this structure mainly use out of doors or indoor terminal on, its Potential distribution is very good, anti-pollution flashover ability is also very strong, security reliability is very high, mounting means is flexible, installs also very convenient.But similar with aforesaid dry type silicone rubber for cable terminal, have the not high shortcoming of mechanical strength, and the work on the spot amount is also bigger, do not meet the prefabricated development trend of cable termination.
In addition, China Patent No. is No. 02282771.4 utility model patent, a kind of dry type prefabricated capacitor type cable termination is disclosed, by anti-taper capacitance graded bushing, stress cone, the end electric conductor, compositions such as root casing, have the electric conducting material of the arranged in co-axial alignment that staggers successively from the inside to the outside or the capacitance plate that semiconductive material is made in the main insulation of described anti-taper capacitance graded bushing from top to bottom, the inner surface of the root insulating cylinder of described anti-taper capacitance graded bushing is that the little lower end diameter of upper end diameter is toroidal greatly, the insulating end outer surface of described stress cone is that the little lower end diameter of upper end diameter is tapered greatly, the taper insulated outer surface shape of the toroidal inner surface of the root insulating cylinder of described anti-taper capacitance graded bushing and described stress cone is coincide and be there is no slots close and contact, the root insulating cylinder of the toroidal of described anti-taper capacitance graded bushing is made by the high electric strength insulating material, and described stress cone is made by elastomeric material.
This structure is first suit stress cone when mounted, and then anti-taper capacitance graded bushing is installed.Although its advantage is light and handy, mounting means is flexible, and is easy for installation, but the cable termination of this structure also has corresponding shortcoming:
At first, the root insulating cylinder of its anti-taper capacitance graded bushing, described by its specification, make with the insulating material that mechanical strength is higher, if this pipe participates in the tolerance insulation on stress cone top, then, because the size after the cable body insulation processing can't guarantee, matching problem between this insulating cylinder and cable body insulation is difficult to solve, unless pour into insulating oil or other flexible insulating material in air gap between the two; Secondly, cable body insulation pretreatment portion bit length is also long, and its technological requirement also is very high, otherwise break down easily; Once more, in this structure, owing to bear the problem of main insulation, also much higher for the insulating requirements of stress cone than common oil-filled stress cone type; Also have, cooperate because stress cone inner surface and outer surface all relate to tight no air gap, assembly technology requires also very high.
