Description
Technical field
The utility model relates to the high-voltage electrical apparatus field, and especially a kind of 1100KV extra-high voltage series compensation is used bypass isolating switch.
Background technology
What transmission line installed that string mends that device can increase substantially existing and newly-built transmission line additional send electric energy power and electricity net safety stable property, is that most advanced, most representative flexible ac transmission is one of technological.Compare with the newly-built circuit of electrical network, have characteristics such as cost is low, applied widely, saving transmission of electricity corridor, can produce good economic benefit and social benefit, meet the developing direction of building strong intelligent grid.High voltage isolator is that string is mended very important switching device in the engineering, and it plays buffer action in circuit, so that the maintainer can carry out safety operation and outage working service to power equipment.The patent No. is that 2010201088498 Chinese patent discloses the telescopic outdoor high-voltage alternating current isolating switch of a kind of twin columns level; The telescopic outdoor high-voltage alternating current isolating switch of this twin columns level is made up of three one poles; Two post insulators and dynamic and static contact that each one pole includes base, rotating insulated pillar, is arranged side by side, said moving contact is located in two post insulators through a Foldable telescopic arm, and fixed contact is located on another post insulator; Said Foldable telescopic arm comprises contact tube, following contact tube; Said down contact tube is articulated in through its lower end that activity vertically is equipped with pull bar on the corresponding post insulator and in inside, and the lower end of said pull bar is articulated on the corresponding post insulator, and the upper end of following contact tube is provided with gear box; Gear inwardly is provided with pinion and rack; The coaxial upper end that is fixed on pull bar of said tooth bar, gear are rotated through a gear shaft and are assemblied on the gear box, and the jointed shaft of the hinged place between the axis of gear shaft and pull bar and the post insulator is parallel and the one of which end stretches out gear box and only revolve with last contact tube and to cooperate; Moving contact adopts the clamp-type contact, and it fixedly is assemblied in the upper end of contact tube; The lower end of following contact tube also is hinged with connecting rod, and flat shape is provided with at interval between jointed shaft between connecting rod and the following contact tube and the jointed shaft between following contact tube and the post insulator, and rotating insulated pillar constitutes space four bar linkage mechanism through a crank and said connecting rod.Can drive down rotating with generation around itself and the pin joint of corresponding insulation column of contact tube during work through the rotation of insulator lies on one's side or uprightly action; Following contact tube drives contact tube stretching, extension or folding through said pinion and rack in motion, thereby accomplishes the break-make between the dynamic and static contact; The divide-shut brake that the telescopic outdoor high-voltage alternating current isolating switch of above-mentioned twin columns level has solved isolating switch to a certain extent impacts big problem; But the last contact tube of its folding retractable arm is positioned at the side that following contact tube deviates from another post insulator that the post insulator with its place is arranged side by side after folding with following contact tube; Therefore when the folding retractable arm stretched the combined floodgate of realizing dynamic and static contact, upper and lower contact tube axis became inverted V-shaped from folded state, becomes V-arrangement then; Finally become conllinear; Be moving contact corresponding when combining with fixed contact be the upwards action of " incision " of footpath from fixed contact, therefore necessarily require the structure that supplies the two mutual " suiting " is set on moving contact or fixed contact, this makes the sealing at the two dynamic and static contact combined floodgate place to guarantee on the one hand; Also define the type of dynamic and static contact on the other hand; Thereby limited its transmission performance, made it can't be applied to the ultra high voltage field, mended in the engineering like the 1100KV string; Simultaneously because dynamic and static contact is radially to cut when closing a floodgate; Therefore make the upper end bearing radial force square of folding retractable arm, accelerated the wearing and tearing of folding telescopic arm and the decline of precision have been shortened the operate as normal cycle of isolating switch.Simultaneously; This isolating switch is not installed folding bus switching current device, thereby does not possess the ability of folding bus switching current, in extra-high voltage series compensation engineering field owing to need the switching string to mend device; The electric current that produces can produce contact and ablate, thereby can't be used for extra-high voltage series compensation engineering field.
