Description
Technical Field
The invention relates to an oil immersed transformer winding integrated with an optical fiber deformation sensor, an installation process and a system, and belongs to the technical field of power transformers.
Background
In a power system, an oil-immersed transformer is used as one of main devices of the power system, and the operational reliability of the oil-immersed transformer is directly related to whether a power grid system can safely operate or not.
With the increasing capacity of power grids, transformer damage accidents caused by short-circuit faults are on the rise. The statistical data of the national grid company shows that accidents happen 162 times in 2002-2006 in the 110kV and above voltage class transformers of the national grid, wherein the damage accidents caused by external short circuits account for 36.4%. When the transformer is subjected to short circuit impact in operation, permanent instability deformation such as winding distortion, inclination, collapse, bulge and displacement can be generated on the winding under the action of electrodynamic force. As is found when the deformation is not timely, the accumulated effect may further increase the deformation, which may result in insulation damage, turn-to-turn short circuit, inter-cake breakdown, main insulation discharge or complete breakdown.
In the short-circuit state of the power transformer, short-circuit current which is dozens of times larger than that in normal operation flows through a winding to generate huge electromagnetic force which comprises radial force, axial force and circumferential force. When the short-circuit resistance of the winding is insufficient, the winding is damaged by electromagnetic force. After the transformer winding is deformed, some transformer windings can be damaged immediately, and more transformer windings can still continue to operate for a period of time. The main forms of short-circuit damage of the transformer include:
(1) radial instability of windings
Radial instability means that all wires of the whole wire cake protrude outwards in a certain stay interval in the circumferential direction of a winding, or all wires of the whole wire cake recess inwards in an adjacent stay interval, or both deformations exist simultaneously. Such local deformations are not only asymmetrical in the circumferential direction, but also do not necessarily occur for all the cakes over the axial height of the winding.
(2) Axial instability of windings
The collapse of some of the wire cakes of the winding under the combined action of axial dynamic short circuit forces and radial short circuit forces is commonly referred to as axial instability of the winding. Axial buckling is the primary failure mode of windings that are subject to both axial dynamic short circuit forces and radial short circuit forces (whether radial tensile short circuit forces or radial compressive short circuit forces).
The short-circuit current interacts with the radial leakage flux component to generate an axial dynamic short-circuit force. If the axial pre-compression force of the winding is smaller than the axial dynamic short-circuit force, under the action of the axial short-circuit force, gaps can be generated between the wire cakes, between the wire cakes and the cushion blocks and between the cushion blocks at certain parts of the winding (such as the end part of the winding with larger radial magnetic flux leakage component and a voltage-regulating distribution area); when the short-circuit current is zero, the "air gap" of each part disappears. The repeated appearance and disappearance of the 'gaps' in the short circuit process inevitably cause the violent collision between the wire cakes and the wire cakes, between the wire cakes and the cushion blocks and between the cushion blocks. As a result of such a violent collision, the insulation of the turns of the wire is broken to cause an inter-turn short circuit, and the spacers are loosened and displaced and the wire is inclined and collapsed due to the combined action of radial short-circuit forces. If the axial pre-compression force of the winding is too large, the lead is easy to incline and collapse directly. In addition, the larger the ratio of axial height to radial width of an individual wire, the more likely the wire will collapse.
In order to find the winding deformation of the transformer on line in time, find problems in advance and take effective preventive measures in time, reduce transformer accidents and prolong the service life of the transformer, the winding deformation of the transformer in operation can be monitored in real time by installing the optical fiber winding deformation sensor on the oil-immersed transformer, the winding deformation of the transformer in different degrees can be found in time, and the operation reliability of the oil-immersed transformer is improved.
