Problems solved by technology

[0002] SF 6 Gas-insulated transformers are mainly used in places where the population is concentrated in large cities. At present, gas-insulated transformers with a voltage level of 110kV and below are used. For gas-insulated transformers with a voltage level of 110kV and below, only a few transformer manufacturers can produce them; The 220kV voltage level gas-insulated transformer has not yet been related to manufacturing and application. With the planning of domestic cities and power systems, the demand for 220kV gas-insulated transformers has gradually been put on the agenda. Therefore, the technical development of 220kV voltage level transformers become a need

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention will be further described by examples.

[0024] figure 1 Shown is the internal body structure of the 220kV voltage level gas insulated transformer according to the present invention: iron core 1, low voltage coil 2, low voltage coil end insulation 3, coil pressure plate 4, main insulation 5, high voltage coil 6, high voltage coil end insulation 7. High-voltage end and tap top outlet 8, enclosure 9, high-voltage head outlet 10, high-voltage end and tap bottom outlet 11, lower insulation 12, and body support plate 13.

[0025] The low-voltage head and the low-voltage end are axially drawn out from the upper and lower ends of the coil through the body; the high-voltage head is drawn out from the middle in the width direction, and a two-way parallel structure is adopted, and the high-voltage end and the tap head are drawn out from both ends of the coil , the two-way parallel connection places the high-vo...

Abstract

The invention relates to a 220 kV gas insulation transformer, and belongs to the technical field of transformers. According to the technical scheme, the 220 kV gas insulation transformer comprises a box, SF6 gas, an SF6 gas sleeve, a cable box, a transformer body, a transformer on-load voltage regulation switch, a gas density gauge, a pressure monitoring device, a sudden pressure relay, a gas temperature gauge, a winding temperature gauge, a plate radiator, a gas circulation pump, an airflow indicator, a blowing device and a cooling system intelligent control box, wherein the SF6 gas, the SF6 gas sleeve and the cable box are used for outgoing of a 220 kV high-voltage cable, the transformer body comprises an iron core, a coil and a lead, the gas density gauge, the pressure monitoring device, the sudden pressure relay, the gas temperature gauge and the winding temperature gauge are used for secondary protection, the plate radiator, the gas circulation pump, the airflow indicator, the blowing device and the cooling system intelligent control box are used for cooling the transformer, and an internal insulating and cooling medium of the transformer is the SF6 gas. Compared with a traditional oil-immersed transformer, the 220 kV gas insulation transformer has higher fire resistance, explosion resistance and safety and more complete monitoring and protection configuration, thereby being more suitable for being used in population concentration places such as city centers.

Description

technical field [0001] The invention relates to a 220kV voltage grade gas-insulated transformer, which belongs to the technical field of transformers. Background technique [0002] SF 6 Gas-insulated transformers are mainly used in places where the population is concentrated in large cities. At present, gas-insulated transformers with a voltage level of 110kV and below are used. For gas-insulated transformers with a voltage level of 110kV and below, only a few transformer manufacturers can produce them; The 220kV voltage level gas-insulated transformer has not yet been related to manufacturing and application. With the planning of domestic cities and power systems, the demand for 220kV gas-insulated transformers has gradually been put on the agenda. Therefore, the technical development of 220kV voltage level transformers become a need. Contents of the invention [0003] The purpose of the present invention is to provide a 220kV voltage level gas insulated transformer, wh...
