Abstract
A low-leakage-flux high-voltage current transformer comprises an iron core and a secondary winding wound around the iron core. A low-leakage-flux coil formed by windings which are wound in a subsection mode with the sections identical in turn number is arranged on the circumference of the outer portion of the secondary winding, and the windings are connected in an end-to-end mode. Due to the fact that the low-leakage-flux coil is added, effects of an external magnetic field on operation of the current transformer can be reduced and prevented, and electric performance and accuracy of the current transformer are ensured.
Description
Technical field
The utility model relates to GIS ultrahigh voltage power equipment technical field, particularly is applied in the low magnetism leakage high-tension current inductor that uses in the GIS superhigh pressure combined electric appliance equipment.
Background technology
Cooperate the TPY level Current Transformer for Transient Protection of GIS superhigh pressure combined electric appliance equipment use and have the metering that the instrument safety coefficient requires; measure with permalloy current transformer unshakable in one's determination; after being installed in the superhigh pressure combined electrical apparatus; because in the ultrahigh voltage power system; the conveying network flow is big; conveying circuit voltage height; in service at the networking; can produce very big magnetic field around the high voltage electric equipment; be installed in high voltage electric equipment between phase and phase and every current transformer in mutually be subjected to easily that external magnetic field is disturbed and influence; reduce the accuracy class of current transformer itself, thereby cause the certainty of measurement decline of superhigh pressure networking and route protection out of control.
Summary of the invention
In view of the foregoing, the purpose of this utility model provides a kind of low magnetism leakage high-tension current inductor that is not subjected to external magnetic field to disturb and influence, and guarantees electric property and the accuracy of current transformer.
The purpose of this utility model is achieved in that it comprises iron core and the secondary winding that is wound on this iron core, it is characterized in that: be provided with the low magnetism leakage coil of the sealing that the winding by segmentation coiling and every section equal turn numbers constitutes in the exterior periphery of above-mentioned secondary winding, the origin or beginning of each section winding is connected respectively with end.
The utility model shields the low magnetism leakage coil of winding owing to added conduct, thereby can improve and prevent influenced by external magnetic field when current transformer from moving, and makes it to guarantee electric property and the accuracy of current transformer.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
By accompanying drawing as can be known, this low magnetism leakage high-tension current inductor low magnetism leakage coil of comprising iron core 1, secondary winding 2 and being constituted by four sections equal turn numbers windings 3,4,5,6.On secondary winding in current transformer 2 exterior periphery of the winding 3,4,5,6 of four sections equal turn numbers after coiling is finished respectively, the origin or beginning of every section winding is connected respectively with origin or beginning, end is connected respectively with end, be that winding 3,4,5,6 origin or beginning 3-1,4-1,5-1,6-1 are connected, winding 3,4,5,6 terminal 3-2,4-2,5-2,6-2 are connected, constitute the secondary circuit of a sealing, by adjusting and changing the hop count of this winding and the sectional area of winding conducting wire, can produce different anti-leakage field effects.
