Abstract
A converter assembly includes a converter with converter valves, each having power semiconductor switches. At least one fluid-tight encapsulation housing, in which at least some of the power semiconductor switches are disposed, forms a modular converter unit. The encapsulation housing is at least partially filled with an electrically insulating insulation fluid in order to electrically insulate the power semiconductor switches disposed in the encapsulation housing.
Claims9
A converter assembly, comprising:
- a converter including:
- a plurality of separate fluid-tight encapsulation housings;
- a plurality of modular converter units each disposed in a respective one of said separate fluid-tight encapsulation housings;
- said plurality of modular converter units having converter valves each including power semiconductor switches;
- an electrically insulating insulation fluid at least partly filling said plurality of separate encapsulation housings for electrically insulating said power semiconductor switches disposed in said plurality of separate encapsulation housings;
- and
- pas-insulated or liquid-insulated electrical lines interconnecting said plurality of modular converter units to form said converter.
