Transformer oil purifier operation-1

The 1st step of the transformer oil purifier operation is to know the functions of the main parts of the oil purifier.

We would like to list the following; it is the ZYD-II-50 machine, as the example.

Main Spare Parts Introduction

● Primary filter: Remove the big impurities which are biggest than 30μ, it can avoid the jam in each oil pipe and reduce the abrasion of oil pump. It is stainless Steel, washable.

● Secondary filter and fine filter: UK APUREDA filter, the precision is 1μ

● Condensation: The water in heated oil forms vapor in vacuum tank, and then the vapor forms liquid water due the low temperature in condensation. The condensation not only reduces the temperature of vacuum pump, but also it also reduces the frequency of changing vacuum pump oil so that it can enlarge the lifetime of vacuum pump.

● Vacuum pump and Roots pump: Providing vacuum source

● Oil pump: Transfer the oil which is exhausted the gas to outside.

● Heater: Heat oil

● Vacuum sensor and pressure sensor: Detects vacuum value and pressure value

● Double-infrared level sensor: Connect the oil pump and electromagnetic valve to control oil pump and electromagnetic valve, keep inlet and outlet oil balance.
