Abstract
The invention discloses a 220kvGIS power distribution device. The device comprises an all-optical fiber electronic current transformer. The all-optical fiber electronic current transformer comprises an electric unit. The electric unit is connected with three optical sensitive loops, namely an A-phase optical sensitive loop, a B-phase optical sensitive loop and a C-phase optical sensitive loop, through connecting optic cables. The device is characterized in that: the all-optical fiber electronic current transformer is positioned outside a GISSF6 air chamber and is arranged at a zero level. The device has a simple structure, does not change the primary structure of a GIS body, is only arranged outside a GIS air chamber, can effectively improve the working reliability of the GIS body and the electronic current transformer and is convenient to maintain and replace at the same time.
Description
Technical field
The present invention relates to a kind of 220kV GIS power distribution equipment, especially relate to the mounting means of the full fiber type electronic current mutual inductor in a kind of 220kV GIS power distribution equipment, belong to technical field of electricity.
Background technology
Along with carrying out of intelligent substation pilot building-up work comprehensively, electronic mutual inductor is used owing to its no magnetic saturation, advantages such as frequency response range is wide, transient characterisitics good, clean environment firendly progressively begin pilot.The electronic mutual inductor volume is little, in light weight, good insulation preformance, be convenient to install with the primary equipment integral type, at these unique appearance characteristics, many test units, producer have all dropped into the optimization mounting means that very big energy is studied electronic mutual inductor and primary equipment.Compare with outdoor AIS, the SF6 air-tightness of indoor GIS is had higher requirement to the mounting means of electronic type.
All things considered, electronic mutual inductor mainly contains two kinds at the mounting means of GIS at present, and mode 1 is to be placed directly in GIS plenum chamber inside, and with traditional the same layout of instrument transformer, this kind mode mainly is applicable to the Luo-coil electronic current mutual inductor; Mode 2 is to be placed on the outside junction of GIS plenum chamber, seals installation with the flange mode, and this kind mode mainly is applicable to the full fiber type electronic current mutual inductor.The major advantage of mode 1 is not change original GIS structure basically, and shortcoming is that the environmental suitability to electric mutual inductor requires height; The major advantage of mode 2 is the environmental suitability requirements to electric mutual inductor of having weakened, and shortcoming is to do some adjustment to original GIS structure.
Summary of the invention
Technical problem to be solved by this invention provides the mounting means of a kind of full fiber type electronic current mutual inductor in 220kV GIS power distribution equipment, can reach the purpose that convenient, reliable operation, easy access, optimization size are installed.
For solving the problems of the technologies described above, the invention provides a kind of 220kV GIS power distribution equipment, comprise the full fiber type electronic current mutual inductor, described full fiber type electronic current mutual inductor comprises electric unit, electric unit by connect optical cable and A mutually, B phase, C mutually three optical sensitive rings link to each other, it is characterized in that: described full fiber type electronic current mutual inductor places outside the GIS SF6 air chamber, and zero potential is installed.
Aforesaid 220kV GIS power distribution equipment is characterized in that: described optical sensitive ring set is loaded on the excircle outside of the housing of GIS SF6 air chamber.
Aforesaid 220kV GIS power distribution equipment is characterized in that: optical sensitive ring outer setting has protective casing.
Aforesaid 220kV GIS power distribution equipment is characterized in that: the optical sensitive ring compresses by screw or pressing plate and is installed on the mounting seat.
The beneficial effect that the present invention reached:
1. install simply, do not change GIS body original structure: only install additional outside the GIS air chamber and get final product, can effectively improve the functional reliability of GIS body and electronic current mutual inductor: (1) sensing ring places outside the air chamber, to the airtight no any harmful effect of GIS.If sensing ring is placed within the air chamber, then need optical fiber is drawn from air chamber, optical fiber is different with cable, can not bear big stress, can not seal by poured with epoxy resin; (2) avoid gas that sensing ring is exerted an influence.In the GIS air chamber, because breaker operator and partial discharge etc., chemical reaction can take place in SF6, and the subfluoride of generation may exert an influence as optical fiber, insulation loam cake etc. to the various nonmetallic materials on the sensing ring; (3) avoid the design of GIS high pressure is exerted an influence.Because sensing ring is installed on outside the GIS housing, place zero potential, so sensing ring does not produce any influence to the high pressure design of inside.If sensing ring is placed in the air chamber, then need to carry out detailed high pressure design and experimental verification.
2. easy access and replacing: all parts all are installed on the earth potential place, overhaul and change very convenient;
3. can optimize the power distribution equipment size: saved the installation site of CT in the air chamber, further compression optimization GIS power distribution equipment size is saved floor space.With mode 2(in the prior art is full fiber type electronic current mutual inductor mounting means in 110kV GIS) compare, there is obvious superiority in the present invention aspect installation convenience and the maintenance replacing convenience.

Embodiment
Below be example with 220kV GIS full fiber type electronic current mutual inductor (FOCT) mounting means at 220kV intelligent substation pilot station, the concrete enforcement of this programme is described.
The present invention has designed FOCT(full fiber type electronic current mutual inductor) at the mounting means of 220kV GIS, under the situation that does not change the GIS original structure, finished the installation of FOCT, technical solution is described in detail as follows:
FOCT mainly is made of sensing ring 2, connection optical cable 11, electric unit 5 etc., and Fig. 1 is the composition schematic diagram of FOCT, and A, B, C three corresponding three groups of optical sensitive rings link to each other with the casing of electric unit by connecting optical cable respectively.The sensing ring profile as shown in Figure 2.
Concrete mounting means is: 220kV GIS power distribution equipment is that three-phase divides box structure, comprise GIS SF6 air chamber 3, be provided with GIS bus 10 in GIS SF6 air chamber 3, the sensing ring 2 of FOCT links to each other with electric unit 5 by connecting optical cable 11, and electric unit 5 links to each other with merge cells by optical cable.Optical sensitive ring set 2 is loaded on the excircle outside of the housing 4 of GIS SF6 air chamber 3, zero potential is installed, link to each other with the housing 4 of GIS SF6 air chamber, every phase GIS SF6 air chamber 3 arranged outside have 4 optical sensitive rings, be provided with protective casing 8 in optical sensitive ring outside, protective casing 8 is installed on the mounting seat 9, optical sensitive ring body is an aluminum alloy materials, can bear big pressure, therefore this sensing ring both can be installed by 4 M10 screws, also can compress by pressing plate to be installed on the mounting seat 9.The casing of every corresponding electric unit is provided with two, two groups of electrical control gears are housed in each casing, be whenever to have 4 groups of electrical control gears to be connected with corresponding 4 optical sensitive rings respectively mutually, totally 6 electric unit casings of three-phase is installed on the outer support of GIS SF6 air chamber.
