Application
The Big Touch Screen Type Transformer Vacuuming Machine Series RNVS is an advanced vacuum evacuation solution designed for transformer manufacturing, installation, commissioning, and maintenance. Equipped with a PLC fully automatic control system and a 10-inch colour touch screen, the RNVS series provides intuitive operation, real-time monitoring, and precise vacuum control for power equipment vacuuming processes.

This intelligent vacuuming system allows operators to clearly view the equipment running status and real-time vacuum level, and to set target vacuum parameters according to actual working requirements. Once the preset vacuum degree is reached, the system can automatically maintain the vacuum for a specified period and then shut down as set, or operate continuously for a preset number of hours before automatic stop, ensuring safe, stable, and efficient operation.
It can be used for:
1. Vacuum evacuation of power transformers, distribution
transformers, and reactors
2. Vacuum processing of capacitors and other electrical power
equipment
3. Transformer factories, substations, power generation plants, and
power utilities
4. Industrial vacuum processes such as vacuum drying, vacuum
impregnation, and related applications
Advantage
1. Wide Capacity Range & Customizable Solutions
The RNVS series offers a broad capacity range to meet different
application requirements. Standard models are available from 252
m³/hour to 2160 m³/hour, while customised large-capacity systems
can be designed to reach 4000 m³/hour, 8000 m³/hour, or even higher
according to project demands.
This flexibility makes the RNVS series suitable for various
transformer sizes and on-site conditions.
2. PLC Fully Automatic Control System
Enables fully automatic operation with precise control logic,
reducing manual intervention and human error.
3. 10-Inch Color Touch Screen Interface
Provides clear visualization of operating status, real-time vacuum
degree, alarm information, and system parameters.
4. Intelligent Vacuum Control Function
Supports setting target vacuum value and holding time. The system
will automatically maintain the vacuum and shut down once the set
conditions are met.
5. Flexible Operating Modes
Allows operation for a preset duration (e.g. several hours) with
automatic shutdown, suitable for unattended operation.
6. Real-Time Monitoring & Data Display
Displays vacuum level, operating time, system status, and key
parameters in real time for easy supervision.
7. High Reliability & Safety Protection
Designed with stable control logic and multiple protection
functions to ensure long-term safe operation.
