The present application belongs to the field of extra-
high voltage bushing electrical test, and particularly relates to a
bushing electrical test automatic conversion device and method, which comprises a
remote computer operating system, a conversion control box main body, a conversion control box
front panel and a conversion control box rear panel. The front part of the conversion control box main body is provided with the conversion control box
front panel. The present application realizes real-time
visual monitoring of test state, channel selection and grounding condition through
remote operation of a computer interface isolated by an
optical fiber, utilization of an integrated
system touch screen,
multiplexing buttons and multi-color state indicator lights, red
dielectric loss output indication, orange
partial discharge output indication and green grounding indication. An operator can quickly judge the
system operation state through intuitive light signals. The
dielectric loss setting button and the
partial discharge setting button adopt
multiplexing logic design, and channel enabling, switching and grounding control can be completed through simple clicking. In combination with the parameter setting and state monitoring functions of the touch screen, the operation complexity is greatly reduced.
