Abstract
The utility model discloses a 220kV GIS line-outgoing structure. A bus isolation switch, an overhaul ground switch I, a current transformer, a circuit breaker, a current transformer, an overhaul ground switch II, a line-outgoing isolation switch, a voltage transformer, a casing tube, and a lightning arrester. The back of the casing tube is provided with an open-type ground switch. Through employing the above technical scheme of the utility model, the structure can greatly improve the capability of opening and closing electromagnetic coupling of the open-type ground switch and the capabilities of electrostatic induction voltage and current, thereby meeting the requirements of an actual engineering for the opening and closing of electromagnetic coupling of the open-type ground switch, and the electrostatic induction voltage and current. The application prospect of the structure is wide. If the structure is further prompted, the requirements of the opening and closing of electromagnetic coupling and the electrostatic induction voltage and current are met, wherein the requirements are imposed on the ground switch at a side of a 220kV GIS line of a transformer substation from double or more circuits on the same tower in the actual engineering.

Technical field
The utility model relates to the GIS outlet arrangement of a kind of 220kV.
Background technology
Conventional 220kVGIS outlet, line side earthed switch is positioned at Cubicle Gas-Insulated Switchgear shell, as Fig. 1, be followed successively by bus isolating switch 2, inspection earthing switch I 3, current transformer 4, circuit breaker 5, current transformer 4, inspection earthing switch I I6 from bus 1 side toward outgoing line side, outlet isolating switch 7, high speed grounding switch 8, charged display device 9, voltage transformer 10, sleeve pipe 11, lightning arrester 12.Wherein high speed grounding switch 8 important function is to coordinate circuit breaker to realize single-pole reclosing: in the time of circuit generation single-phase fault, produce one time electric arc, fault phase circuit both sides circuit breaker trip, but due to the electromagnetic coupled between normal phase and fault phase and electrostatic induction, after an arc extinction, produce and dive for electric arc (secondary arc), the high speed grounding switch of fault phase circuit both sides closes ground connection, dive for arc extinction, high speed grounding switch disconnects, reclosing action, fault phase circuit breaker reclosing.
According to the ability of line side earthed switch folding electromagnetic coupled and electrostatic induction voltage, electric current, earthed switch is divided into category-A, category-B, super category-B.Wherein the ability of category-B earthed switch folding electromagnetic coupled and electrostatic induction voltage is: electrostatic induction voltage 20kV, electrostatic coupling induced current 10A, electromagnetic coupled induced voltage 15kV, electromagnetic coupled induced current 160A.At present, the inner earthed switch of GIS that mainly GIS equipment manufacturers produce is both at home and abroad in category-B level, and partial parameters can be accomplished super category-B level.In actual engineering design, the electrostatic induction voltage of part common-tower double-return circuit meets or exceeds 25kV, but GIS equipment manufacturers still do not possess the ability of manufacturing this horizontal grounding switch.
Summary of the invention
The purpose of this utility model is to provide a kind of 220kV GIS outlet structure of Practical Project to line side earthed switch folding electromagnetic coupled and electrostatic induction voltage, current capacity requirement that meet.
For achieving the above object, the utility model is by the following technical solutions:
A kind of 220kV GIS outlet structure, be followed successively by bus isolating switch, inspection earthing switch I, current transformer, circuit breaker, current transformer, inspection earthing switch I I, outlet isolating switch, voltage transformer, sleeve pipe and lightning arrester from bus bar side toward outgoing line side, open type earthed switch is set after sleeve pipe.
Charged display device is set after outlet isolating switch.
Adopt the utility model of technique scheme, the ability of open type earthed switch folding electromagnetic coupled and electrostatic induction voltage, electric current can be accomplished very large, can meet the requirement of Practical Project to line side earthed switch folding electromagnetic coupled and electrostatic induction voltage, current capacity.This technology has a extensive future, if further promoted, can solve common-tower double-return in Practical Project or the more requirement of multiloop number to the 220kVGIS of transformer station line side earthed switch folding electromagnetic coupled and electrostatic induction voltage, current capacity.
