How to Perform Step down Transformer Lamp Repairing

There are manufacturers across the world offering premium transformers repairing services. This post is about repairing the lamp of step down transformer at your own. This project will require the components of the lamp- bulb, transformer, and base. Apart from this, you will also require a soldering iron, power strip, and a little multipurpose tool used by technicians.

What’s inside the black box?

One of the lacking of the design of transformer lamp is the remote transformer inside a plastic box. The transformer is placed halfway between the ends of a power cord i.e. approx. 6 ft long. Transformer is a heavy component that the manufacturing company might have had a better design with reliable packaging. When the plastic case was unboxed, experts observed:

• Damaged plastic black case
• Step down coil with magnetic core
• Fractured output connector
• Primary side coil hardwired to AC power cord

Steps to Follow:

1. Remove the potting material and access the leads of the primary side coil

Electrical component manufacturers rapidly pot their products with non-conductive material. This offers robustness to the product and make it safer for consumer. Electrical devices are built with sensitive components and with potting, manufacturers make them immobilize. This further helps them in making the device more robust and resistant to mechanical shock and abrasion.

High voltages can be a safety hazard, so potting material’s electrical isolation property prevents accidental electrical short circuits that can result in fire incident, fatalities, or injuries.

2. Reconnecting the primary winding leads to the AC power cord

This is an additional step included in the troubleshooting process as the soldered connections may have been damaged by first step. Regardless of the time when leads were damaged or distorted, the connections were broken when inspected without potting material across the primary winding.

3. Apply power to the transformer and check proper operation

Output Connector Story

Inspection of the lamp’s transformer revealed the damaged done to the output connector. However, when you see from the outside, you won’t find any disorder, but initially the connector has been fractured. This makes transformer unable to perform and function properly. You can hire some technicians if you are unable to perform Transformers repairing job your own.

How You Can Sustain Your Transformer Spares Good Condition?

Here we will explain how to maintain and use transformer bushings. In general, there are two designs of bushings used on transformers- solid porcelain bushings on smaller transformers and oil-filled condenser bushings used on larger transformers.

Solid porcelain bushings contain high-grade porcelain cylinders that conductors pass through. Outside surfaces have a series of skirts that helps in increasing the leakage path distance to the grounded metal case. Bushings made for high voltage are usually oil-filled condenser type. These bushings have a central conductor wound with alternating layers of paper insulation and tin foil. You can fill it up with insulating oil.

Exporters Of Power Transformers From India Sharing Cooling Methods Of Transformer

The cooling arrangement of the transformer varies according to the size and capacity of the transformer. When both the capacity and size increased, the arrangement becomes extra powerful and sophisticated. In other words, transformer cooling system us an arrangement intended for power transformers that limits the released heat into a safe value with proper dissipation of generated heat.

Power transformers exporters in India supply distinct range of cooling systems for different transformers (mainly dry type transformers and oil immersed type transformers).

In dry type transformers, air is used as a coolant whereas in oil filled transformers, both air and transformer oil are used as the coolant medium. Different types of cooling methods used for transformers are as follows-

  1.Air Natural Type

This cooling method is used in dry type transformer that is having smaller ratings. This technique uses natural air, which is circulated inside the system to eliminate generated heat. These transformers are also known as self-cooled transformers in the market. This type of cooling system offers satisfactory operation, but it is limited to low voltage transformers only.

  2.Air Forced Type

This type of cooling method is used in dry type transformer and can be used in oil filled transformer as well. In this method, cool air with extreme pressure is provided to the core. The high speed fans installed in the system produce high velocity of air to the transformer.

  3.Oil Natural Air Natural Cooling (ONAN)

This system is used in oil immersed type transformers. This is the easiest method to cool down the oil immersed transformers.

  4.Oil Natural Air forced (ONAF)

Air is forcefully applied to the transformer, which is produced by high speed fans equipped inside the transformer.

  5.Oil Forced Air Forced (OFAF)

Big oil immersed transformers release more heat and for these transformers, special cooling techniques are introduced by the experts. Oil forced air forced cooling system includes both oil and air that are circulated at high speed by some extra configuration.

All these methods are specifically used for a specialized transformer device. Exporters of power transformers India have shared this information just to make the users aware of these techniques to cool down their transformer devices.

Transformer Oil And Its Properties

Insulating oil or transformer oil is a refined mineral oil. This highly refined mineral oil has excellent electrical insulating property in comparison with other mineral oils. They (highly refined mineral oil) are stable at high temperature. They are used in different fields like in suppress corona, high voltage switches, fluorescent lamp ballasts, high voltage capacitors and also in the circuit breakers.

Filtration Of Transformer Oils – How it Works

Modern transformers have several requirements because of greater electrical stress in fluids and insulating materials. For such requirements we have to maintain lower residual water content and better dielectric strength of oil to handle those stresses. We have to treat insulating fluids from time to time in a proper way. Transformer oil filtration services will improve the properties of entire system of transformers. Insulating fluids are used in transformers as effective coolants and also as a dielectric material. Different functions are performed with transformer oils like to suppress corona, for insulation process and also for arcing.
