Introduction:
Model ZLH transformer Vacuum Pump System is used in transformer installation and maintenance for transformer vacuum drying and Transformer vacuum pumping.
Features:
1. Apply for vacuum drying and vacuum measurement of transformers, tap changers, SF6 switches, etc.
2. Cooling type: natural air-cooled. The vacuum pump exhaust port is provided with device for condensing and collecting moisture.
3. Easy operation, control system has the alarm functions with phase sequence, over-voltage, short-voltage, leakage detection, etc.
4. Almost free maintaining, Automatic operating control.
5. Vacuum pump with self-check valve, vacuum pump interlock, in the power outage or vacuum pump stop automatically closed when the check valve.
6. Digital Pirani vacuum gauge is installed to detect the vacuum degree of the transformer.
