Abstract
The utility model relates to a kind of composite silicone rubber isolated bus terminals, comprising with composite silicone rubber is the bus bulk of main insulating layer, and the heat-shrinkable T bush be set in described bus bulk, described bus bulk end sleeve has terminals, and described terminals and described heat-shrinkable T bush interference fit form step conical.Composite silicone rubber isolated bus terminals of the present utility model, by terminals and heat-shrinkable T bush interference fit are formed step conical, seal tight, ensure that the pressure at the interface of heat-shrinkable T bush and silicon rubber contact position, thus ensure that the dielectric strength of isolated bus.
Description
Technical field
The utility model relates to the silicon rubber insulation bus in power transformation engineering field, particularly relates to a kind of composite silicone rubber isolated bus terminals.
Background technology
The terminal connection method of existing isolated bus has two kinds, and a kind of is that the end of bus adopts electric capacity ring indentation method successively, and its shortcoming is the finite elastic of material, easily chaps in operation, causes insulation breakdown, and technique is comparatively complicated; Another kind is that the terminal of bus adopts wrapped band method, and shortcoming is the stress evacuating measure almost not adopting metallic shield end, has the possibility punctured in operation.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides the terminals of the composite silicone rubber isolated bus that a kind of structure is simple, interfacial insulator intensity is larger and reliable.
For achieving the above object, the technical solution adopted in the utility model is: a kind of composite silicone rubber isolated bus terminals, it is characterized in that: comprising with composite silicone rubber is the bus bulk of main insulating layer, and the heat-shrinkable T bush be set in described bus bulk, described bus bulk end sleeve has terminals, and described terminals and described heat-shrinkable T bush interference fit form step conical.
In the utility model preferred embodiment, comprise the overlap joint end plate that described terminals comprise flat further, described bond end intralamellar part is provided with the ventilation hole running through its two ends, is provided with the cushion block being close to its upper and lower both sides in described ventilation hole.
In the utility model preferred embodiment, comprise further on described overlap joint end plate and be also provided with several screws.
In the utility model preferred embodiment, comprising described cushion block is further copper bar.
The utility model solves the defect existed in background technology, composite silicone rubber isolated bus terminals of the present utility model are by forming step conical by terminals and heat-shrinkable T bush interference fit, seal tight, ensure that the pressure at the interface of heat-shrinkable T bush and silicon rubber contact position, thus ensure that the dielectric strength of isolated bus.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
In figure: 10, bus bulk, 20, interior table be resistance to factice appearance is heat-shrinkable T bush, 30, terminals, 31, overlap joint end plate, 32, ventilation hole, 33, cushion block, 34, screw.
Embodiment
Be described in further detail the utility model in conjunction with the accompanying drawings and embodiments now, these accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of composite silicone rubber isolated bus terminals, comprising with composite silicone rubber is the bus bulk 10 of main insulating layer, and the interior table be set in described bus bulk be resistance to factice appearance is heat-shrinkable T bush 20, and bus bulk 10 end sleeve has terminals 30.Breakdown strength because of silicon rubber under standard state is 20 ~ 24kV/mm, and composite silicone rubber solid insulated busbar make use of this mechanism of solid dielectric insulation high breakdown strength just, and volume is little, and the insulation level born is high.Interior table is resistance to factice appearance is that heat-shrinkable T bush 20 is as protective layer, because interfacial insulator intensity and interfacial pressure have direct relation, therefore, terminals 30 and heat-shrinkable T bush 20 interference fit are formed step conical, dielectric interfacial pressure is larger, the dielectric strength at interface is higher, increase to a certain degree in interfacial pressure, the dielectric strength at interface can close to the electrical strength of this medium body, afterwards, interfacial pressure increases again, the dielectric strength at interface no longer includes and rises appreciably, terminals 30 and interior table are resistance to factice appearance is that heat-shrinkable T bush 20 adopts interference fit to form step conical, seal tight, interfacial pressure can be guaranteed, thus ensure that the dielectric strength of isolated bus.
Further, terminals 30 comprise the overlap joint end plate 31 of flat, be provided with the ventilation hole 32 running through its two ends, be provided with the copper bar cushion block 33 being close to its upper and lower both sides in ventilation hole 32 in overlap joint end plate 31 inside.Because composite silicone rubber solid insulated busbar is hollow conductor, terminals 30 are opened air holes 32 and forms internal diameter air channel, internal diameter air channel energy self-assembling formation hot-air convection, radiating condition is good, when the terminals 30 of two isolated buses connect, temperature rise can not higher than self conductor temperature.Therefore, offer ventilation hole 32, can make isolated bus good heat dissipation, temperature rise is low.
For convenience of overlap joint, overlap joint end plate 31 is also provided with several screws 34.
Composite silicone rubber isolated bus terminals of the present utility model, by terminals and heat-shrinkable T bush interference fit are formed step conical, seal tight, ensure that the pressure at the interface of heat-shrinkable T bush and silicon rubber contact position, thus ensure that the dielectric strength of isolated bus.
Above according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related personnel in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification, must determine technical scope according to right.
