The difference and form of a Dry-type transformer

In my country, epoxy resin vacuum casting Dry-type transformer dominates the market. In addition, from the main distribution transformers to power plant excitation transformers, plant transformers, rail transit traction rectifier transformers, high-current electric furnace transformers, nuclear power plants, marine, oil production platforms, and other special transformers and multi-purpose multi-field development. In recent years, Zhejiang Shuntong Electric Co., Ltd. has developed and mass-produced these special products in many fields. What is the difference and form of a Dry-type transformer? Here are some answers.

What is the difference between a Dry-type transformer and an oil-immersed transformer?

Dry-type transformers and oil-immersed transformers are the two most used transformers. Compared with oil-immersed transformers, Dry-type transformers have better fire protection performance and are mostly used in places with higher fire protection requirements. Such as hospitals, airports, stations, and other places. But relatively speaking, the price is higher, and there are certain requirements for the environment, such as not being too humid, not having too much dust and dirt, etc. In addition, the operational maturity of Dry-type transformers is not as good as that of oil-immersed transformers.

The difference between inverter and Dry-type transformer.

The required power frequency (50hz, 60hz, etc.) can be achieved through the adjustment of the inverter to meet our special needs for electricity. Dry-type transformers are generally "bucks" and are commonly found near communities or factories. The function of the Dry-type transformer is to reduce the ultra-high voltage to the normal electricity voltage of our residents to meet people's daily electricity consumption.

The form of a Dry-type transformer.

Open

It is a commonly used form. The body of the Dry-type transformer is in direct contact with the atmosphere and is suitable for a relatively dry and clean room. When the ambient temperature is 20 degrees, the relative humidity should not exceed 85%. Generally, there are two cooling methods: air cooling and air cooling.

Closed

The Dry-type transformer is in a closed enclosure and is not in direct contact with the atmosphere. Due to poor sealing and heat dissipation conditions, it is mainly used in mining and is of explosion-proof type.

Pouring

It is cast with epoxy resin or other resin as the main insulation. It has a simple structure and small volume, which is suitable for Dry-type transformers with smaller capacities.
