A method using an electric power feeding unit, a plasma spray coating system, and a plasma spray coating system.

Title:

A method using an electric power feeding unit, a plasma spray coating system, and a plasma spray coating system.

Document Type and Number:

Japanese Patent JP6055169

Kind Code:

B2

Abstract:

Different plasma spray guns (210) have differing current and voltage requirements for their operation. The spray guns (210) generally fall into low voltage high current and high voltage low current types. The power requirements of the guns (210) vary greatly in terms of overall power ranging from few tens of kilowatts to few hundreds of kilowatts. The guns (210) also have wide ranging requirements for voltage and current. A power delivery unit (230) is described in which the unit (230) is capable of delivering the wide range of power as well as the wide ranges of voltage and current. A plasma spray system (200) with such power delivery unit (230) can universally operate both the low voltage high current and high voltage low voltage spray gun types. Such system (200) can reduce capital and operation costs since shops need not maintain separate and incompatible plasma spray systems.
