01Applications

Application

For the centralised purification of insulating oil at large power stations and regional grid centres, and for emergency repairs during maintenance periods. The capacity of one unit meets the daily purification volume handled at regional grid level.

Suitable oils

Insulating oils such as new oil, imported oil, extra-high-voltage transformer oil, instrument transformer oil and reactor oil.

Materials

Standard: high carbon steel; custom-built: 304 stainless steel

Working principle

Two vacuum pump sets can run as main and standby, so a single unit covers the daily volume handled at regional grid level. Level, foam, pressure and temperature are monitored online as complete parameters, which supports continuous unattended running.

02Overview

High-capacity purification equipment for large power stations and regional grid centres, for centralised insulating oil treatment and for emergency repairs.

Each machine is designed and built to the company standard and goes through a no-load and a full-load run test before it leaves the works. The test record and the certificate of conformity travel with the machine. Yanneng can work out the right configuration and the treatment line from the oil analysis report and the site conditions you provide.

03Main features

01
Power station capacityThe capacity of one unit meets the need for centralised purification of insulating oil across a large regional grid and for emergency handling during maintenance periods.
02
Dual pump set redundancyA main and standby vacuum pump set can be configured, which raises the reliability of continuous running, because servicing one set does not stop the work.
03
Round-the-clock online runningLevel, foam, pressure and temperature are monitored as complete parameters, so the unit supports continuous unattended running.
04
Efficient heatingFar-infrared radiation heating is combined with automatic temperature control, and the oil temperature is adjusted within 20–80 °C, which reduces the energy consumption.
05
Modular filter elementsThe filter elements use a quick-change structure, so routine replacement needs no special tools and the maintenance time is short.
06
Pre-integrated in the factoryThe piping, the electrical system and the interlocks are commissioned during the manufacture of the machine, so only the pipe connections and the power supply are needed on site.
