Description
Technical field
The utility model relates to a kind of power equipment, especially relates to the structural improvement of a kind of solid ring main unit unit cabinet connected system.
Background technology
In the whole electric power system of country, a kind of solid ring main unit of high pressure unit cabinet connected system 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 and be called a kind of solid ring main unit unit cabinet connected system on the high-tension switch cabinet general custom.A kind of solid ring main unit unit cabinet connected system 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 a kind of solid ring main unit unit cabinet connected system 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 " a kind of solid ring main unit unit cabinet connected system " 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 " a kind of solid ring main unit unit cabinet connected system ".Take out a kind of solid ring main unit unit cabinet connected system and be the implication of not seeing " looped network " in fact separately.These a kind of solid ring main unit unit cabinet connected systems all little, thereby the high-voltage switch gear of a kind of solid ring main unit unit cabinet connected system 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 a kind of solid ring main unit unit cabinet connected system generally is an on-load switch.A kind of solid ring main unit unit cabinet connected system 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, " a kind of solid ring main unit unit cabinet connected system " 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 a kind of solid ring main unit unit cabinet connected system 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 a kind of solid ring main unit unit cabinet connected system 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 a kind of solid ring main unit unit cabinet connected system or vacuum circuit-breaker, dry-type transformer, dry type mutual inductor have just got into flickering building.A kind of solid ring main unit unit cabinet connected system 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.A kind of solid ring main unit unit cabinet connected system 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 a kind of solid ring main unit unit cabinet connected system again conversely; Not only function admirable but also the seriation of current a kind of solid ring main unit unit cabinet connected system, this has more expanded the scope of application of a kind of solid ring main unit unit cabinet connected system.
A kind of solid ring main unit unit cabinet connected system has been realized by a kind of solid ring main unit of insulating oil unit cabinet connected system the technology promotion process of--a kind of solid ring main unit of sulfur hexafluoride gas unit cabinet connected system---firm silicone rubber, a kind of solid ring main unit of epoxy resin unit cabinet connected system; 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 a kind of solid ring main unit of solid unit cabinet connected system, and overall structure is small-sized, compact, easy for installation and be convenient to change advantage such as part accessory.
