SCB14-1600KVA dry-type transformer is a commonly used power equipment, which adopts dry-type transformer technology and has high performance and safety. This transformer is widely used in various power systems and industrial fields for applications such as step-up, step-down, and transformer. The following is a detailed introduction to the transformer, including its working principle, structural characteristics, use and maintenance, etc.

First, the working principle

The working principle of SCB14-1600KVA dry-type transformer is similar to that of oil-immersed transformer, which is based on the principle of electromagnetic induction. When alternating current passes through the primary side, a changing magnetic field is generated, which is transmitted to the secondary side through the core. On the secondary side, due to the change in the magnetic field, an induced electromotive force is generated, which enables a voltage change.

Unlike oil-immersed transformers, dry-type transformers use air as the insulating medium instead of transformer oil. This makes dry-type transformers safer and more environmentally friendly because they do not produce leaks and contamination like oil-immersed transformers.

Second, structural characteristics

The main structural features of SCB14-1600KVA dry-type transformer are as follows:

Iron core: The transformer is made of high-quality silicon steel sheets, which has the characteristics of high permeability and low hysteresis loss. The shape and structure of the core are optimized to reduce reluctance and eddy current losses and improve the efficiency of the transformer.

Winding: Winding is an important part of the transformer, which is wound with copper wire or aluminum wire. The primary side winding and secondary side winding of the transformer are connected to the power supply and load respectively to realize the voltage transformation. The windings of dry-type transformers use air as the insulating medium, which is sealed and protected by pouring epoxy resin or spraying epoxy powder and other materials.

Heat dissipation system: In order to ensure the normal operation and service life of the transformer, dry-type transformers usually use natural cooling or forced air cooling for heat dissipation. The SCB14-1600KVA dry-type transformer adopts a forced air cooling system, which sends cooling air into the transformer through a fan or ventilator to take away the heat and discharge it.

Protection level: Since dry-type transformers are usually installed indoors or outdoors, they need to have a certain degree of protection to adapt to different environmental conditions. The protection rating of the SCB14-1600KVA dry-type transformer is IP20, which means that it can prevent the ingress of solid foreign objects with a diameter greater than 12.5mm and prevent the ingress of water droplets.

Noise levels: Dry-type transformers typically have lower noise levels because they use air as the insulating medium and do not require the use of oil pumps and fans for heat dissipation like oil-immersed transformers. The noise level of SCB14-1600KVA dry-type transformers is usually between 50-70 decibels.

3. Use and maintenance

In order to ensure the normal operation and service life of SCB14-1600KVA dry-type transformer, the following measures need to be taken:

Installation environment: The transformer should be installed in a dry, well-ventilated place, no violent vibration, no corrosive gas. At the same time, the surrounding dust and dirt should be cleaned regularly to ensure the normal operation of the transformer.

Regular inspection: The transformer should be inspected regularly, including parameters such as appearance, fasteners, winding temperature, etc. If an abnormality is found, it should be dealt with and recorded in a timely manner.

Maintenance: The transformer should be maintained regularly, including cleaning the surface, checking the fasteners, etc. At the same time, the heat dissipation system of the transformer should be checked regularly to ensure that it is operating properly.

Precautions: When operating the transformer, you should pay attention to safety to avoid electric shock accidents. At the same time, it should be avoided to place flammable materials around the transformer to avoid causing fire.

Spare parts replacement: When damaged, the corresponding spare parts should be replaced in time, such as windings, radiators, etc. When replacing spare parts, spare parts that match the original equipment should be selected to ensure the normal operation and service life of the transformer.

Recording and reporting: A sound recording and reporting system should be established to monitor and record the operation of the transformer in real time. When an abnormal situation is found, it should be reported to the relevant departments for handling in a timely manner. At the same time, the operation and maintenance of the transformer should be regularly reported to the superior leaders.
