Problems solved by technology

[0003] If the large-capacity single-phase AC transformer is directly connected to the three-phase AC system, the load of the three-phase AC system will be seriously unbalanced, the utilization rate of the power supply capacity will be greatly reduced, and the operation of the three-phase AC system will be adversely affected.

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] The main circuit of the balanced flexible temperature rise test device is as follows: figure 1 As shown, it mainly includes three-phase single-phase conversion transformer, output winding adjustable temperature rise transformer, and adjustable load reactor group.

[0017] Three-phase single-phase conversion is to convert three-phase power supply to single-phase power supply, so as to improve the utilization rate of power supply capacity and reduce the influence of single-phase load on power supply imbalance. The wiring of the conversion transformer is as figure 2 shown.

[0018] The connection mode of the primary and secondary sides of the conversion transformer is: three-phase iron core columns, the middle iron core columns are not covered with coils, each side of the iron core columns is equipped with a primary winding and two secondary win...

Abstract

An equilibration and flexible temperature rising test device of thyristor valve consists of three-phase to single phase conversion transformer CTPSPCT for converting three phase power to be single phase power, output winding adjustable temperature rising transformer and adjustable load reactor for adjusting current at power supply outlet .It is featured as using three-phase iron core to form primary and secondary edge wire structure of TPSPCE with its primary side being three-phase V form wiring and secondary side being single output ,applying 0.5:1:0.5 as current ratio of TPSPCE three-phase inlet wire for realizing equilibration of inlet wire current .

Description

technical field [0001] The invention relates to a device for performing a temperature rise test on a thyristor valve in a power system and power electronics technology, in particular to a balanced and flexible temperature rise test device for a thyristor valve. Background technique [0002] With the gradual promotion of the application of power electronics technology in power systems, high-voltage valves based on thyristor series voltage equalization technology have become the core components of various high-power power electronic devices. For example, static var compensator (SVC), thyristor controlled series compensator (TCSC), direct current transmission (HVDC), etc. The operation test of the thyristor valve is an important test method related to improving the design and manufacturing level of various high-voltage series thyristor valves and improving their reliability. At present, the temperature rise test is an important part of the thyristor valve operation test. For ...
