Dry transformer

What is a dry transformer?

Dry transformers are transformers that change the voltage of an electric current, while also working in environments with high temperature and humidity.

Dry transformer application

LS CAST RESIN transformers are used in many different fields, typically:

- Indoor and outdoor transformer stations.
- Offshore drilling platforms.
- Commercial buildings.
- Hospital.
- Mall.
- water supply and wastewater treatment industry.
- Traction systems.
- Power supply for high-end air conditioning system.

Characteristics of the transformer - dry

Environmental friendliness: Dry transformers do not produce oil or toxic gases that pollute the atmosphere. Therefore, this series is very environmentally friendly and the optimal choice to replace other devices, typically an oil transformer.

High overload capacity: The machine has epoxy resin molding coil with high heating time coefficient, can withstand higher overloads.

Moisture resistance: Epoxy resin molding wire increases the resistance of the insulator and does not reduce the insulation properties caused by moisture. These reactions age the insulation materials, even after a long period of no maintenance.

Able to resist pulse voltage

+ The dry transformer is resistant to electrical impulses up to 200 kV thanks to its special architecture and careful design.

+ The machine is also extremely easy to maintain, no need to check the oil level as well as testing oil. Due to humidity, The plastic molding coil does not reduce the insulation properties so it is easy to check the machine, including the coil.

+ Epoxy coil has non-flammable properties, self-extinguishing and fire resistant by electric sparks.

+ The core of the machine is covered with epoxy resin so it has the ability to reduce noise significantly.

Advantages and disadvantages of dry transformers

Advantages

• Long service life, less damage.
• Can work in harsh environments.
• Do not pollute the environment when operating.
• Durable operation, can work for long consecutive hours with high efficiency.
• Compact design, convenient for moving and installing.

Disadvantages

• Upon the occurrence of damage related to the coil will have to change the whole structure (Change the entire coil in high voltage, low voltage and pillar from).
• Dry transformers are judged to be more expensive than oil-cooled transformers of the same capacity and voltage.

Common types of dry transformers

Dry plastic transformer

Used in areas with high humidity, because the primary and secondary windings are encased in epoxy resin which prevents the ingress of water vapor which affects the coil material. Therefore, the transformer can be operated without interruption in areas with high humidity and moisture absorption.

The capacities of these transformers range from 25 KVA to 12,500 KVA, with insulation class F (90oC).

Advantages:

• Good overload.
• Not flammable or in danger of fire, suitable for indoor installation.
• Good performance due to partial discharge coupled with low losses.
• Can be placed outdoors (in chassis with IP 45 protection).
• Does not dehumidify.

Transformer vacuum pressure

Using non combustible materials as coil insulation materials, the windings of this type of transformer are made in the form of continuous layered metal foil. For high voltage, The coil will be in the form of a disc and connected in series or parallel according to capacity with voltage level. Besides that, The coil insulation is also made of H grade Polyester which helps the machine avoid contamination, protect against high moisture contamination and not be affected by humidity.

Advantages:

• High mechanical strength.
• There is no defect in the insulation.
• No temperature fluctuations.
• Less fire risk.
• Easy maintenance.

Guide maintenance procedures dry transformers

Maintenance is very important during dry transformer use. This will help the machine be protected better, At the same time, it is possible to quickly detect any damage or problem that the machine is facing to take timely action.

Machine maintenance will be performed according to the following procedure:

1. General assessment of the current operating status of the machine.

2. Perform parts inspection: cable section on high and low voltage, magnetic core. If you have discovered the phenomenon of fire, short circuit, they must maintain the fold.

3. Overall cleaning of the machine.

4. Cleaning the parts: parts high pressure, low pressure, magnetic core, cooling fan.

5. Re-adjust the high-voltage and low-voltage terminals.

Check the temperature while operating.
