Abstract

The invention provides a combined optical transformer for a novel GIS. An all-fiber current transformer sensing ring is mounted at one end of a flange body covered by a flange cover board, and an optical voltage transformer sensing head is embedded into a chamber of the flange body; the all-fiber current transformer sensing ring is connected with an external all-fiber current transformer electric unit through a polarization-maintaining fiber; the optical voltage transformer sensing head is connected with an external optical voltage transformer electric unit through a single-mode fiber and a polarization maintaining fiber; the one end of the flange body covered by the flange cover board is mounted at one end of the external GIS through the flange cover board in an abutting mode, the other end of the flange body is mounted at the other end of the external GIS in an abutting mode; parts in the all-fiber current transformer sensing ring, such as the flange body and the flange cover board are separated by employing insulation rings to block ring current, the mounting part is sealed by employing an O-type sealing ring. The combined optical transformer for the novel GIS has advantages of compact structure, insulative, simple and reliable performance, flexible mounting and good sealing performance.

Description

technical field [0001] The invention belongs to the field of transformers and relates to a novel combined optical transformer for GIS. Background technique [0002] With the development of the power system towards high voltage and high current, although the traditional electromagnetic current / voltage transformer is relatively mature, there are engineering problems such as large and bulky transformer, difficult installation, high cost, complex insulation structure, and magnetic saturation phenomenon. Technical deficiencies. [0003] Compared with the traditional electromagnetic transformer, the electronic transformer has the advantages of high precision, high linearity, wide frequency band, small size and light weight. With its advantages in principle, optical transformers have become a new direction in the research of electronic high-voltage transformers. [0004] Metal-enclosed gas-insulated high-voltage switchgear (GIS) has the advantages of reliable operation, high oper...
