Abstract
The invention relates to a load disconnection switch which comprises a cabinet body and three vacuum arc-extinguishing chambers, wherein a partition board is fixedly and crosswise arranged in the cabinet body, the three vacuum arc-extinguishing chambers are respectively and fixedly arranged in three insulating covers, the middle portions of the three insulating covers are respectively and fixedly arranged on three insulating holes which are fixedly arranged on the partition board and distributed in bar-shaped mode, and the three insulating covers are integrated with the cabinet body. The routine that a load switch cabinet is firstly manufactured and then installed in the vacuum load switch is broken, and the load disconnection switch has the advantages of being small in size, capable of saving raw materials, large in on-off capability, safe, reliable, long in service life, capable of being operated frequently, small in maintenance and the like. The load disconnection switch has an obvious disconnection port, can be assembled with a grounding cutter capable of being turned on and off and a power-driven spring mechanism and can be controlled remotely.
Description
Technical field
The invention belongs to the high-voltage alternating current isolating switch technical field, particularly relate to a kind of small size vacuum loading switch and be switch cubicle upper unit independently.
Background technology
Vacuum load switch is the key equipment of distribution and ring network power supply.The a large amount of applied load switches of developed countries are as terminal protection equipment.In the past use breaker protection in China always, cause cost performance very unreasonable, the developed countries on-load switch is 7:1 with the ratio of circuit breaker.At present China's on-load switch is the 1:1 left and right with the ratio of circuit breaker, needs also that active development is rational in infrastructure, the vacuum load switch of dependable performance.The vacuum load switch body of particularly producing both at home and abroad at present is designed to independently unit original paper, more independently vacuum load switch is contained in switch cubicle, makes whole switch cubicle overall dimension large, and complex structure, and maintenance is inconvenient, has hidden danger on electric.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, maintenance is convenient, security performance is high, volume is little integrated load-break switch.
A kind of load-break switch that the present invention proposes, comprise that cabinet, three vacuum interrupters, three isolating switch divide-shut brake conductive components, three isolating switch blade driving mechanisms, three vacuum interrupters close minute operating mechanism and three insulating covers, laterally are installed with dividing plate in cabinet; Three vacuum interrupters are installed in respectively in three insulating covers, and this three insulating covers middle parts is installed in respectively three insulating cover through holes of word order on dividing plate, with cabinet structure in aggregates.
The invention has the beneficial effects as follows: after the vacuum load switch assembling is completed, just completed the main device of cabinet, broken through traditional first loading switch cabinet is completed after, reinstall the version of vacuum load switch, but have volume little, save the advantages such as raw material, connecting-disconnecting function are large, safe and reliable, long service life frequent operation, few maintenance.The present invention has obvious isolation fracture, can be equipped with earthing with making capability and electric spring mechanism, can Long-distance Control.
Description of drawings
Further set forth the present invention below in conjunction with accompanying drawing and case study on implementation.
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with embodiment, a kind of load-break switch of the present invention is described.
As shown in Figure 1, load-break switch comprises that cabinet 1, three vacuum interrupters 2, three isolating switch divide-shut brake conductive components, three vacuum interrupters close minute operating mechanism and three insulating covers 3.The interior dividing plate 4 that laterally is fixed with of cabinet 1, dividing plate 4 is separated into upper space 5 and lower space with cabinet 1 inner space.Upper space 5 is the main bus bar chamber.The top of lower space is switch element Transmission Room 6, and the bottom of lower space is to be arranged with three insulating cover through holes 7 on cable vault's 200 dividing plates 4.Word order is fixed with three insulators 8 on the roof of cabinet 1, is fixed with respectively on the quiet tool rest 21 of 21, three isolation knife of the quiet tool rest of isolation knife in the lower end of three insulators 8 and is fixed with respectively three-phase bus 9.Three insulating covers 3 are structurally identical, and its top is stretched in main bus bar chamber 5 from three insulating cover through holes 7 respectively, and three insulating covers 3 are separately fixed on dividing plate 4.Three vacuum interrupters 2 are installed in respectively the top in three insulating covers 3, and are fixedly connected with corresponding insulating cover respectively.Three isolating switch divide-shut brake conductive components are structurally identical, and it is indoor to be arranged on main bus bar.Isolating switch divide-shut brake conductive component comprises isolating switch blade 10 and quiet end seat 22, and the lower end of quiet end seat 22 connects with the quiet end of corresponding vacuum interrupter 2, and the upper end of quiet end seat 22 is hinged with corresponding isolating switch blade 10.Three isolating switch blades 10 are when "on" position, respectively with quiet tool rest 21 contacts of corresponding isolation knife.Three isolating switch blade driving mechanisms are structurally identical, include insulated tension pole 12, rotating shaft 13 and connecting lever 14.Connecting lever 14 1 end solid weldings are in rotating shaft 13, and an end of the other end of connecting lever 14 and insulated tension pole 12 is hinged, and the other end of insulated tension pole 12 and isolating switch blade 10 are hinged.Two ends of rotating shaft 13 are supported by two axle beds 11 on the upper surface that is fixed on dividing plate 4 respectively.Three vacuum interrupters to close minute operating mechanism structurally identical, be separately positioned in switch element Transmission Room 6, each vacuum interrupter closes a minute operating mechanism, comprises main shaft 15, main shaft connecting lever 16, insulated tension pole 17, conducting rod connecting lever 18.One end of main shaft connecting lever 16 is fixed on main shaft 15, one end of the other end and insulated tension pole 17 is hinged, the other end of insulated tension pole 17 is hinged with an end of the conducting rod connecting lever 18 that is arranged on insulating cover 3 interior bottoms, conducting rod connecting lever 18 connects by bearing pin and insulating cover 3, slide block 23 on the other end of conducting rod connecting lever 18 and the moving conductive rod of vacuum interrupter 19 is hinged, a be flexible coupling end of 24 of copper is sleeved on moving conductive rod 19, and carries on the back tightly on moving conductive rod 19 by nut.Be flexible coupling 24 the other end of copper is fixed on insulating cover 3.Be set with contact pressure spring 25 above being positioned at slide block 23 on moving conductive rod 19.The two ends of main shaft 15 are supported by two axle beds that are fixed on dividing plate 4 lower surfaces respectively.Due to the contact pressure spring being housed in upper end of slide block, the combined floodgate rear spring is compressed, and the distance between motion block lower end and nut is overtravel.In the situation that guarantee the compressed amount of spring, whole adjustment is very succinct, convenient.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
