Project Description

Performance and Usages

ZYD-P PLC control Transformer Oil Purifier. It adopts Programmable Logic Controller(PLC) to achieve fully automation of the oil purifying processing. ZYD-P can quickly remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil’s dielectric
strength, effectively making sure electric equipments working safely and normally.
ZYD-P Transformer Oil Purifier can increase the dielectric insulation value more than 35KV at one time. It suits for purifying all kinds of insulation oil, especially suits for purifying transformer oil from 110KV and above 110KV UHV power transmission and distribution projects; also suits purifying of capacitor oil, mutual inductor oil, switch oil, cable oil.

Functions

Removing Moisture. The final treated oil can achieve less than 3ppm

Degassing. The final treated oil can achieve less than ≤0.05%

Removing Particles. The final treated oil can achieve1 micrometer

Vacuum oil injecting

Vacuum drying equipment for transformers

Vacuum purification online work, unattended operation.

Technical Features

  • PLC chips is from Siemens or the appointed brands.
  • “T ”type double vacuum separation technology, double stages thin film drying degassing technology, double evaporation area and degassing time.
  • Patented degassing tank: anti-foam structure & Dual electronic foam monitoring system “( key components are from Switzerland), completely eradicating oil entering into vacuum pump.
  • Oil atomized particles size is less than 50um, largely increasing efficiency for water molecules and gas molecules escaping from oil molecules.
  • Vigorously increase contact area between heater and oil (2w/cm2), reduce the surface temperature of heater, and prevent oil cracking and aging.
  • To install liquid level and temperature protector of heater, prevent instantaneous high temperature of heater.
  • Vacuum pump cooler preposition, to reduce water get into vacuum pump, reduce the frequency to change vacuum pump oil and extend vacuum pump lifetime.
  • High precision filtering element, fine accuracy is 1 micron(optional: 0.5 micron),β≥1000.
  • Outlet oil pressure protector, to monitor pressure of oil filters all the time, effectively protecting machine and operators.
  • Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak.
  • Adopt the high pressure oil pump, oil transmission stable, low noise, long life
  • Using famous brand high quality components, performance is stable and reliable.
  • Automatic float ball & electronic oil level automatic controlling system, to realize unattended operation.
  • Easy operation and trouble reminder and trouble shooting tips.
