I. Introduction
GDKZ-IV Vacuity of Arc Chute Test Set adopts computer to conduct the synchronous control and data collecting processing, it enables the site test sensitivity of vacuum degree in arc extinguish chamber reach 10-4—10-1Pa. The most conspicuous characteristics is that it adopts the new type exciting winding and data processing method, and realizes the un-dismantling measuring of vacuum degree.
GDKZ-IV Vacuity of Arc Chute Test Set has the characteristics of convenient usage, simple operation, undismantling measuring and high precision; it is a practical test device and is widely used in the departments that use vacuum switch such as electric power, iron and steel, petrochemical, textile, coal and railway.
