Description
A kind of arc control device assembly, the outdoor vacuum arc control device assembly that particularly a kind of 66KV is above.
The vacuum arc control device (also have person it for vacuum bubbles) that open circuit divide indoor and outdoor two kinds, and indoor switch vacuum arc chamber generally leans on supporting insulator insulating support rod etc. to be fixed on the frame.Outdoor switch vacuum interrupter is that arc control device are contained in the insulating sleeve, or in the cabinet of other form, makes dielectric with oil or SF6 gas, connects and composes switch with other mechanism again.But for the outdoor vacuum circuit breaker more than the 66KV, no matter adopt which kind of above-mentioned form, all undesirable, in decades to the above electric pressure of 66KV, many employing oil switchs, but the arc extinction performance of oil switch is relatively poor, and the fluid in the switch is easily descended by dielectric after the electric arc carbonization, and oil liquid leakage goes out easily contaminated environment of back, thereby the maintenance capacity of oil switch is big.In recent years, develop some 6 sulfur fluoride gas switchs (SF6) again, this switch arc quenching effect is better, but SF6 gas environmental pollution is bigger, and health is had a significant impact, and equipment also is corrosive, and therefore, requires very high to production environment and manufacturing equipment.
The purpose of this utility model, be to provide a kind of arc quenching effect good, it is all littler than oil switch, SF6 switch to open distance between the dynamic and static contact, close a floodgate, opening velocity is fast, stable performance, dynamic and static contact contact area behind combined floodgate is big, and tight above each the electric pressure outdoor vacuum arc control device assembly of the 66KV that can satisfy advantages such as high-current switch design that waits coincide.
The utility model is achieved by the following technical programs, the vacuum extinction chamber assembly that this 66KV is above, it is by inlet wire terminal block 1, waterproof cover 2, upper end cover 3, fixed contact 4, last insulating sleeve 5, moving contact 6, radome 7, guide plate 8, bellows components 10,22, insulation board 12, insulator support 13, current transformer 14, connector 15, outlet terminal block 16, conductive clip 17, conducting rod 9, insulated connecting rod 19, following insulating sleeve 21 and bottom end cover 24 are formed, it is characterized in that: upper end cover 3 is equipped with at the top of going up insulating sleeve 5, fixed contact 4 and inlet wire terminal block 1 are housed on the upper end cover 3, the fixedly guide plate 8 of conducting rod 9 usefulness is equipped with at the middle part of last insulating sleeve 5, one radome 7 is housed above the guide plate 8, insulation board 12 and insulator support frame 13 are equipped with in the bottom of last insulating sleeve 5, current transformer 14 is housed on the insulator support 13, a bellows components 10 and 22 respectively are equipped with in the top of conducting rod 9 and insulated connecting rod 19 bottoms, moving contact 6 is equipped with in conducting rod 9 upper ends, a conductive clip 17 is equipped with in the bottom, conductive clip 17 18 is connected to outlet terminal block 16 by being flexible coupling, one insulated connecting rod 19 is arranged at the bottom of conductive clip 17, last insulating sleeve 5 connects insulating sleeve 21 down by connector 15, and a bottom end cover 24 is equipped with in the bottom of following insulating sleeve 21.Last insulating sleeve 5 an and transducer 11,20 and vacuum detecting 23 respectively is housed on the inwall of insulating sleeve 21 down.Bellows components 10 1 ends and conducting rod are fastening, and the other end and insulation board 12 are fastening, and bellows 22 is fastening with insulated connecting rod 19, and the other end and end cap 24 are fastening.Last insulating sleeve 5 reaches down and is vacuum in the insulating sleeve 21.
The utility model has the advantages that: arc quenching effect is good, opens between the dynamic and static contact apart from little, and the moving contact stroke distances is short, closes a floodgate, opening velocity is fast, and ampacity is big, stable performance, and 10 years are non-maintaining, and the life-span can reach 40 years.
The utility model will be further described below in conjunction with accompanying drawing:
Accompanying drawing is above each the electric pressure outdoor vacuum arc control device assembly structure schematic diagram of 66KV;
Above each the electric pressure outdoor vacuum arc control device assembly work of this 66KV is that the connecting levers below bottom end cover 24 drive insulated connecting rod 19 and conducting rods 9 move up and down, and the moving contact 6 of its upper end is contacted with fixed contact 4 or separates, and realizes what it opened or closed.When moving contact 6 contact fixed contacts 4, then electric current is by moving contact 6, conducting rod 9, and conductive clip 17 and be flexible coupling 18 reaches outlet terminal block 16.Produce electric arc when preventing that moving contact 6 from contacting with fixed contact 4 and metal ion sprays, one metallic shield 7 is installed, prevent the damage of insulated tube inwall at last insulating sleeve 5 inwalls.In order to make vacuum and the air insulated in the insulated tube, in the upper end and insulated connecting rod 19 lower ends of conducting rod 9 bellows components 10,22 is housed respectively, bellows components 10 1 ends and conducting rod 9 are fastening, and the other end and insulation board 12 are fastening.Bellows components 22 1 ends and insulated connecting rod 19 lower ends are fastening, the other end and bottom end cover 24 fastening formations.Because at the above electric pressure voltage of 66KV height, to open between the dynamic/static contact apart from wanting big, the stroke of moving contact is also corresponding big, and the stroke of common bellows is about 10: 1, is 100mm as the length of bellows, and promptly development length is about 10mm.The ratio of elongation of this utility model bellows components 10,22 is 10: 3, has reduced the volume of vacuum interrupter widely.In addition, current transformer 14 is housed in insulating sleeve, transducer 11 and 20 and vacuum detecting 23 can be measured its switch operating current and vacuum degree easily.This utility model is simple in structure, installs, easy to use, close a floodgate, opening velocity is fast, and stable performance, 10 years are non-maintaining, and the life-span can reach 40 years.
