Transformer oil vacuum processing equipment

• Purpose: Can handle various mining transformer oils and vegetable oils

The process is fully automated

This system adopts a touch screen (Siemens)+PLC (Siemens) automatic control operation mode. It can set, display, record, measure, and control all backup equipment in real-time.

After a sudden power outage, the device can save various parameters and program execution status, and execute corresponding operating procedures to keep the system in a safe state. After power is restored, it can continue to execute from the original process or manually intervene to execute from a certain process as needed.

Process data such as vacuum degree, temperature, process time, etc. are automatically recorded by the computer in the form of curves and lists.

• It can filter impurities from various oil products and remove micro water and micro gas content from the oil products

·Vacuum system:

(1) Using a vacuum pump with the ability to remove water vapor as the front-end pump can effectively prevent damage to the vacuum pump caused by emulsification of the vacuum pump oil.

(2) Adopting anti backflow oil and water design, the coil is free from contamination

(3) Equipped with a vacuum oil-gas separator, it can effectively separate transformer oil. An internal liquid level sensor is installed. During the vacuum pumping process, if the transformer oil is pumped into the vacuum pipeline due to improper operation or control failure, the liquid level control switch of this tank will send a signal and the vacuum valve will immediately close. Alarm prompts the operator to detect the cause.

·Multiple safety protections for thermal oil heating system

(1) Adopting the safety type thermal oil electric heating center specially developed by Shenrui, it has high safety and eliminates safety tolerance.

(2) The heating circuit is equipped with a contactor adhesion automatic release device to prevent safety accidents caused by overheating, and is also equipped with an overheating alarm.

Alarm prompts the operator to detect the cause.

The vacuum oil storage tank is equipped with a self circulating degassing system, which can receive oil filtered by an oil filter or perform self circulating degassing through the oil filter. The qualified oil is transported through a diaphragm pump and pipeline to the vacuum oil injection equipment in the workshop. After the oil injection is completed, the residual transformer oil in the pipeline can also be vacuum pumped back to the vacuum oil storage tank for storage.
