Ring main unit (Ring Main Unit) is in one group of high-tension switch gear is contained in metal or non-metallic insulation cabinet or makes the electrical equipment of assembled compartment ring network power supplying units, its core uses on-load switch and fuse, has simple in construction, volume is little, price is low, can improve power supply parameter and the advantage such as performance and power supply safety.It is widely used in power distribution station and the box-type substation of the load centers such as Urban Residential District, skyscraper, large public building, factory and enterprise.
In order to improve power supply reliability, make user can obtain power supply from both direction, generally power supply network is connected into annular.This power supply mode is referred to as ring network power supply.Exchanging in 10kV distribution system at industrial and mining establishment, residential quarters, harbour and skyscraper etc., because load capacity is little, its high tension loop generally uses on-load switch or vacuum contactor to control, and is furnished with high-tension fuse protection.This system generally uses ring network to power, and used high-tension switch cabinet general custom is referred to as ring main unit.Ring main unit is in addition to powering to this distribution substation, the through current (electric current i.e. powered to adjacent distribution substation through this distribution substation bus) of its high voltage bus annular electric supply to be passed through net, therefore the high voltage bus cross section of ring main unit to select with looped network through current sum according to the load current of this distribution substation, to ensure to run mesohigh bus not running overload.Annular cabinet product category is a lot, such as HK-10, MKH-10,8DH-10, XGN-15, SM6 and FOX-HD series.
Ring main unit (Ring Main Unit) is generally divided into air insulation, solid insulation and SF6 and insulate three kinds; for a deciliter load current; cut-off short circuit current and no-load transformer electric current; certain distance overhead transmission line, the charging current of cable run; rise and control and protective effect, be ring network power supply and important switchgear that terminal is powered.In cabinet, joining air-insulated on-load switch mainly has air-generating, air pressing type, vacuum type, and the on-load switch joining SF6 insulation is SF6 formula, and owing to SF6 gas confinement is in housing, the partition fracture that it is formed is invisible.On-load switch in ring main unit, typically requires three stations, i.e. cuts off load, isolates circuit, reliable ground.Air-generating, air pressing type and SF6 formula on-load switch easily realize three stations, and vacuum interrupter can only cut-off, it is impossible to isolation, so General Proper airport logistic park loop-network switch cabinet adds a disconnecting switch before on-load switch, to form isolation fracture.
There are many ring main units on the market at present, but in actual motion, there is problems in that the high pressure connected mode of existing ring main unit uses the connect-disconnect plug of the most European or American male-tapered separable connector being fabricated to by common glue product material and silastic material, product material is uneven, quality technology is unstable, there is very big potential safety hazard when product runs；It is higher for the requirement of mounting process, if wherein the pad of bolt face anyway is installed incorrect, it becomes possible to the sealing causing separable connector is not enough, thus forms the conductive channel that air enters, thus causes operation power potential safety hazard；Being limited by physical dimension, it is impossible to enough space is less, current-carrying capacity requires to run in big environment to cause soil, design, space makes, the wasting of resources in structure；Caulking gum body is the most naked to be exposed on the external in running environment, it is impossible to effectively prevent the destruction of toy and mechanical external force, exterior shield layer and product structure from the most seriously causing electrical operation potential safety hazard once impaired；Being limited by material own, storage period and aging period are the most close, and product will gradually lose original memory and shrink elasticity, and gradually loosen from outer cone sleeve pipe, thus increase operation power potential safety hazard；Connect adnexa and instrument because the restriction of acceptor's creepage distance of insulation, it is impossible to enough the highest such as in electrical operation environmental requirement: metallurgical, mine, subway, long-play in the often high load capacity such as traffic railway electrification or overload operation environment.
Summary of the invention
