Smart Power Transformer Self-Dehydrating Breather with Pressure gage

Transformer breathing is the process of oil expansion and contraction due to temperature changes in the transformer.

 When the oil temperature rises, it pushes the air out of the transformer tank through a device called a transformer breather.

When the oil temperature drops, it draws the air in through the breather. The breather contains silica gel, which absorbs moisture from the air and prevents it from entering the oil. 

Not all transformers have breathers, only those that have oil and are not sealed. 

Smart breathers are a type of breather that can monitor and control the moisture level, temperature, and pressure of the transformer oil and communicate with a remote system

  • Eco
  • Intelligence
  • Maintenance-free
  1. The main function of the Smart Power Transformer Dehydrating Breather is to remove and dry sundries and moisture entering the air of the transformer oil conservator due to the change of transformer oil temperature, to maintain the insulation strength of transformer oil.
  2. At present, traditional suspended dehumidifiers are widely used, and maintenance personnel must regularly inspect them. Once the desiccant changes color, maintenance personnel must replace it promptly on time, which not only increases the workload but also increases the safety hazards of equipment operation. Therefore, it is necessary to use a new type of Smart Power Transformer Dehydrating Breather, which has the following features: automatic constant temperature heating and drying, recyclable desiccant, and the ability to detect the conductivity of the internal and connecting pipes of the moisture absorber; Equipped with intelligent communication protocols and interfaces, real-time monitoring, as well as data storage, analysis, mining, and other functions, achieving a maintenance-free intelligent solution for power Smart Power Transformer Dehydrating Breathers.
  3. Under the requirements of the State Grid Corporation of China for the development of modern smart grid data applications, higher requirements have been put forward for equipment monitoring and maintenance. Traditional moisture absorbers lack necessary monitoring methods when left unattended, and are cumbersome in terms of maintenance and environmental protection. The new MYJZ series maintenance-free intelligent moisture absorbers play a significant role and significance in meeting the requirements of smart grid data monitoring, achieving the “dual carbon” goals, and promoting green environmental protection.

Derived functions of MYJZ series Smart Power Transformer Dehydrating Breather

  1. Monitor the temperature and humidity of the air in the transformer oil conservator 24H x 30 Days.
  2. Intelligent protection of the external operating environment, preventing condensation at the bottom from freezing and affecting the moisture absorber.
  3. The indicator light alarm is convenient for inspection personnel to check and can send an alarm signal to a remote location through preset contacts.
  4. Connect to the main station auxiliary control panel through the RS485 interface output or network interface module of the IEC61850 communication protocol
Smart Power Transformer Self-Dehydrating Dual Tank Breather with Pressure gage MYJZ-400T-Dual silica 6KGS-use for up to 500KV Power Transformer

Working Principle

  1. During the normal operation of the transformer, due to the thermal expansion of the transformer insulation oil, the air in the conservator will pass through the pipeline of the respirator, which is similar to breathing.
  2. When external air is sucked in through a moisture absorber, the air passes through a stainless steel metal filter screen to filter out dust and floating objects in the air, and then flows through a silicone drying chamber.
  3. The moisture in the air is absorbed by the desiccant, achieving the goal of drying the air. The moisture absorber continuously monitors the internal air humidity and transmits the monitoring results to the system control module.
  4. When the air humidity exceeds the programmed value, it indicates that the desiccant has temporarily lost its water absorption capacity and reached a saturation state.
  5. When the internal air is exhaled through the moisture absorber, and the pressure sensor detects a positive signal of internal air pressure, the control unit will activate the heating element laid in the silicone, and the moisture absorber heating module will automatically start, drying the desiccant moisture, thus achieving the regeneration and utilization of environmentally friendly silicone.
  6. The activation of the heating element can only be triggered when exhaling air, ensuring that moist air does not enter the conservator in the form of high-temperature steam.
  7. The high-temperature steam generated during the regeneration process condenses on the inner wall of the glass and flows out through the stainless steel filter screen at the bottom of the moisture absorber to ensure the safety and effectiveness of the regeneration process.
  8. When the ambient temperature is below the programmed value (such as 10 ° C), the bottom auxiliary heating module automatically starts to prevent blockage of the bottom breathing port due to freezing, ensuring that the moisture absorber always maintains a safe and good working condition.
  9. When the moisture absorber malfunctions (such as a control system or heating module malfunction), the external red indicator light of the control box will alarm for easy inspection by operators. Remote alarm signals can be sent through preset contact switches, and all status parameters (temperature, humidity, heating status, fault status, etc.) can be output through the RS485 interface. Remote monitoring of the moisture absorber status can be achieved through remote communication.
  10. At the same time, customers can customize and select network output interface modules that comply with the IEC61850 communication protocol according to their needs, to achieve the access of moisture absorber equipment status information to the substation main station auxiliary control platform.

Installation

  1.    When installing, first remove the sealing flange and sealing ring at the breathing port, replace the sealing ring, and connect the stainless steel oil pipe to the inlet and outlet of the moisture absorber;
  2.  Then unscrew the moisture absorber oil cup, add 1/3 of qualified transformer oil into the oil cup, and then screw it onto the moisture absorber. If the moisture absorber has been installed when the transformer leaves the factory, it is only necessary to unscrew the oil cup of the moisture absorber before the completion of the installation project, add 1/3 of qualified transformer oil into the oil cup and then install it (the oil cup need not be too tight)

One-time installation, safe and reliable, Saving more time and labor cost

Maintain

  1. The replacement of silicone should be carried out in sunny weather and attention should be paid to maintaining a safe distance from the live parts
  2. The replaced silicone can be stir-fried, heated, and dried with a large spoon, and can be reused to reduce operating costs
  3. The heavy gas protection should be switched to a signal
  4. When removing the respirator, the connecting pipe should be blocked to prevent the recovery of air
  5. After replacing with dry silicone, ensure that the oil inside the oil seal does not pass through the breathing nozzle
