Description
Technical field
The utility model relates to a kind of long threeway plug part, especially relates to a kind of long threeway plug part that is used for ring main unit.
Background technology
In the whole electric power system of country, the high pressure ring cabinet is for improving power supply reliability, make the user obtain power supply from both direction, usually power supply network being connected into annular.This supply power mode abbreviates ring network power supply as.Exchange in the 10KV distribution system at industrial and mining enterprises, residential quarters, harbour and skyscraper etc., because of load is held not quite, on-load switch or vacuum contactor control are adopted in its high tension loop usually, and are furnished with the high-tension fuse protection.This system adopts ring network power supply usually, use on the high-tension switch cabinet general custom and be called ring main unit.Ring main unit is except to the power supply of this distribution substation; Its high voltage bus also will be through the annular electric supply net through current promptly through the electric current of this distribution substation bus to the power supply of adjacent distribution substation; Therefore the high voltage bus cross section of ring main unit will be selected in looped network through current sum according to the load current of this distribution substation, to guarantee not running overload of high voltage bus in service.
But from each distribution branch road, obtain being similar to the material benefit of supplying power with double circuit, thereby improved the reliability of power supply.So-called " ring main unit " is exactly that each distribution branch road is established a switch cubicle outlet switch cubicle, and the bus of this switch cubicle is exactly the part of ring main simultaneously.In other words, ring main couples together common the composition by the bus of every outlet cabinet.Every outlet cabinet just is " ring main unit ".Take out a ring main unit and be the implication of not seeing " looped network " in fact separately.These ring main units all little, thereby the high-voltage switch gear of ring main unit does not generally adopt baroque circuit breaker and takes the high voltage load switch of band high-tension fuse simple in structure.That is to say that the high-voltage switch gear in the ring main unit generally is an on-load switch.Ring main unit is operated normal current with on-load switch, and excises short circuit current with fuse, and the two combines and has replaced circuit breaker.Certainly this can only be confined in the constant volume.Such switch cubicle also can be used in the distribution system of non-ring network structure fully, so along with the extensive use of this switch cubicle, " ring main unit " is with regard to the category of having jumped out the looped network distribution and to make a general reference with the on-load switch be the high-tension switch cabinet of main switch.
The time that ring main unit occurs is not very long; But obtained in recent years using widely, if this is main--because the industrial enterprise that new development is got up and the building of public institution, from supplying the angle of distribution; With in; Small-sized capacity generally is no more than 1250KVA for its distribution transformer of great majority, power supply steady in a long-term, and high-voltage switch gear is frequent operation not.For this type user, though the performance of ring main unit is not the most perfect, but enough, adequate.Along with large-scale urban construction, a large amount of large-scale tall buildings things are rised sheer from level ground, and transformer and distribution station often just is located at downstairs; According to the fire-fighting requirement, distribution equipment necessary " no oiling " is according to the reasonable use of building area; Distribution equipment should " miniaturization "; So ring main unit or vacuum circuit-breaker, dry-type transformer, dry type mutual inductor have just got into flickering building.Ring main unit is simple in structure, reliable and safety, and maintenance capacity is very little, and operating cost is low, and compared with the switch cubicle that circuit breaker is housed, advantage is very outstanding.Ring main unit requires on-load switch to have higher performance and littler volume; Novel on-load switch arises at the historic moment; This has driven the technological progress of ring main unit again conversely, not only function admirable but also the seriation of current ring main unit, and this has more expanded the scope of application of ring main unit.
Ring main unit has been realized by the insulating oil ring main unit technology promotion process of--sulfur hexafluoride gas ring main unit---firm silicone rubber, epoxy resin ring main unit; In this change procedure; Product has been realized from oil pollution is arranged--sulfur hexafluoride gas---solid nonpollution material; Small product size from big to small, and the electric cable accessories product that we produce is the connector that designs to the solid ring main unit, overall structure is small-sized, compact, easy for installation and be convenient to change advantage such as part accessory.
The utility model content
The utility model mainly is that the connected mode that solves the most electric cable accessories of existing in prior technology ring main unit cooperates the occupation of land space bigger each other, and corresponding replacing damages the also more high technical problem of cost price of parts product; Provide a kind of a bigger product in occupation of land space is concentrated in a little space, the body that has solved this product is well protected long-pending excessive problem, and also consistent with the function of original product a kind of long threeway plug part that is used for ring main unit.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
A kind of long threeway plug part that is used for ring main unit is characterized in that, comprises the vertical vertical plug part that is provided with and communicates with said level plug part of level plug part and level plug part.
At above-mentioned a kind of long threeway plug part that is used for ring main unit, described level plugs part and vertically plugs the part outer wall and is provided with outer conducting shell.
At above-mentioned a kind of long threeway plug part that is used for ring main unit, be provided with the first trapezoidal pipeline, the second trapezoidal pipeline in the described level plug part and be arranged on the first trapezoidal pipeline and the second trapezoidal pipeline between horizontal pipe.
At above-mentioned a kind of long threeway plug part that is used for ring main unit, second vertical pipe that be provided with first vertical pipe in the described vertical plug part, communicates respectively with first vertical pipe, horizontal pipe and the second trapezoidal pipeline.
At above-mentioned a kind of long threeway plug part that is used for ring main unit, said horizontal pipe outer wall is provided with interior conducting shell.
A kind of long threeway plug part that is used for ring main unit above-mentioned still is provided with insulating barrier between said interior conducting shell and the outer conducting shell.
A kind of long threeway plug part that is used for ring main unit above-mentioned is provided with insulating barrier between the described first trapezoidal pipeline and the outer conducting shell, is provided with insulating barrier between the said second trapezoidal pipeline and the outer conducting shell.
Therefore, the utlity model has following advantage: 1. reasonable in design, simple in structure and complete practicality; 2. take up an area of the bigger product in space with one and be concentrated in a little space, the body that has solved this product is well protected long-pending excessive problem, and also the function with original product is consistent.
