Description
One, technical field: the utility model relates to the multi-functional combination isolation switch of the one pole isolation switch that uses on the high-voltage electric power system and zinc oxide arrester combination.
Two, background technology: at present, a large amount of no-load currents that use the one pole isolation switch to be used to cut-off power consumption equipment provide visible cut-off point in electric power system; Use zinc oxide arrester to provide the inside and outside overvoltage protection to power consumption equipment; A large amount of Transition wire clips that use between isolation switch and other electric equipments are to reduce contact resistance.Because this several prods function singleness can not provide multiple protective to power consumption equipment, though often be used together, often cause the installation framework loaded down with trivial details, operation, operation, maintenance inconvenience, and also the use frame materials is many, has increased installation cost.
Three, summary of the invention: the purpose of this utility model is a kind of collection of design to cut-off the equipment no-load current, have over-voltage protection function, reduce the multi-functional combination isolation switch that uses Transition wire clip.
The purpose of this utility model is achieved in that existing isolation switch comprises stationary electrode, operation draw ring, disconnecting link, moving electrode and insulation support column composition.The utility model is on this basis, the support column that will insulate makes a multifunction insulating support column, in the middle of the insulation support column, run through one and thoroughly do away with the edge plug, the ring resistance sheet is settled in the outside at insulation mandrel, and set up a layer insulating, be connected with lightning-arrest electrode yoke plate in ring resistance sheet bottom, about lightning-arrest electrode yoke plate between the support column lower end insulation spacing body is housed with insulating, after the locking, outside die stamping insulation sheath and cluster parachute group constitute one.Lightning-arrest electrode yoke plate is an electric conductor, and is connected by connection electrode between the base, by the ring resistance sheet, taking shelter from the thunder has connected to form lightning arrester between electrode yoke plate, stationary electrode, moving electrode, connection electrode and the base.For ring resistance sheet and lightning-arrest electrode yoke plate are fully kept in touch, between ring resistance sheet and lightning-arrest electrode yoke plate, be added with metal spring, by the spring support and connection.Joint portion at insulation support column and lightning-arrest electrode yoke plate has silicone rubber jacket to carry out insulated enclosure.Front end at disconnecting link is provided with an arc extinguishing electrode, is provided with the extinguishing arc cover at stationary electrode and disconnecting link abutting end one side, and the arc extinguishing electrode cooperates with the extinguishing arc cover eliminates electric arc.The ring resistance sheet is to be formed by stacking by zinc oxide resistance sheet.
The utility model is on the contour structures basis that does not change existing isolation switch; lightning arrester and arc-control device are combined; have cut-off, the multifunctionality of overload, overvoltage protection; and can prevent effectively that thunderbolt and electric arc accident from taking place, be a kind of desirable renewal product.
Four, description of drawings:
Accompanying drawing is overall structure figure of the present utility model.
Five, embodiment:
Referring to accompanying drawing, existing isolation switch comprise stationary electrode 1, moving electrode 2, operation draw ring 15, disconnecting link 3, base 12 and fix respectively quiet, moving electrode 1,2 about insulation support column 4 form.The utility model is on this basis, and the support column 4 that will insulate makes a multi-functional supporting pillar, runs through one and thoroughly do away with edge plug 5 in the middle of the insulation support column, settles ring resistance sheet 6 in the outside of insulation mandrel 5, and sets up a layer insulating.Connect lightning-arrest electrode yoke plate 8 in ring resistance sheet 6 bottoms, between left and right lightning-arrest electrode yoke plate 8 and insulation support column 4 lower ends 10 insulation spacing body 9 is housed, after the locking, outside die stamping insulation sheath and cluster parachute group 7 constitute one.Lightning-arrest electrode yoke plate 8 be electric conductor and with base 12 between be connected by connection electrode 16, on base 12, be provided with ground hole, be connected with lead ground connection.By having connected to form lightning arrester between ring resistance sheet 6, lightning-arrest electrode yoke plate 8, stationary electrode 1, moving electrode 2, connection electrode 16 and the base 12.Joint portion at insulation support column 4 and lightning-arrest electrode yoke plate 8 has silicone rubber jacket to carry out insulated enclosure.For ring resistance sheet 6 and lightning-arrest electrode yoke plate 8 are fully kept in touch, between ring resistance sheet 6 and lightning-arrest electrode yoke plate 8, be added with metal spring 17, by spring 17 support and connection.Front end at disconnecting link 3 is provided with an arc extinguishing electrode 14, is provided with extinguishing arc cover 13 in stationary electrode 1 and disconnecting link 3 abutting ends one side, and arc extinguishing electrode 14 cooperates with extinguishing arc cover 13 to eliminate electric arc.Wherein ring resistance sheet 10 is made up of annular zinc oxide pressure-sensitive variable resistor stack; The disengaging of lightning-arrest electrode yoke plate 8 is to be realized by the connection electrode between stationary electrode 1 or moving electrode 2 and the lightning-arrest electrode yoke plate 12 16.
During use and since two groups of ring resistance sheets 6 with about lightning-arrest electrode yoke plate 8 be connected and then be connected to base 12 by connection electrode 16, by base 12 ground connection, having constituted overvoltage protection is zinc oxide arrester.When producing overvoltage, overvoltage flows into the earth by stationary electrode 1 (or moving electrode 2), connection electrode 16, lightning-arrest electrode yoke plate 8, ring resistance sheet 6, grounding electrode, plays the overvoltage protection effect.If do not need overvoltage protection operation, remove being connected between lightning-arrest electrode yoke plate 8 and the base 12, as common isolation switch use.
