Understand the Cooling Methods and Advantages of Dry-type Transformers
Dry-type transformers are now mainly used in some high-rise buildings or subways, mainly for lighting equipment or rectified power supplies. At present, as the market environment continues to increase the requirements for high efficiency, energy saving and environmental protection, this type of dry-type transformer has been more and more popular. It is adopted by more and more industries and is widely accepted. So what are the cooling methods and advantages of dry-type transformers?
1. Understand the cooling method of dry-type transformers
The cooling method of the dry-type transformer is air self-cooling or forced air cooling, and its heat dissipation method is air channel heat dissipation, which is safe, flame retardant, fireproof, and pollution-free. It can be directly installed in the load center, maintenance-free, easy to install, and low overall operating cost. . The dry-type transformer has good moisture-proof performance, can operate under 100% humidity, and can be put into operation without pre-drying after shutdown.
2. What are the advantages of dry-type transformers?
The advantages of dry-type transformers are mainly green and environmental protection. The use of new technology and new materials can save energy, reduce noise, and is also conducive to environmental protection.
The advantages of dry-type transformers are also proved by the use of many major projects in terms of safety. Dry-type transformers are relatively safe, especially during peak electricity consumption in summer. Using this type of dry-type transformer has higher safety performance. Such transformers are now used in many technical, medical and production fields. Dry-type transformers are made of high-tech materials, and the research and development in capacity expansion is also excellent. Therefore, if it is used in a city, especially in a city with an expanding population, it can not only provide a stable power demand, but also ensure a certain degree of environmental protection.
The advantage of dry-type transformers is that they rely on air convection for cooling, and are generally used for local lighting and electronic circuits. Transformers such as mechanical equipment, in the power system, general steam turbine transformers, boiler transformers, ash removal transformers, dust removal transformers, desulfurization transformers, etc. are all dry-type transformers, the transformation ratio is 6000V/400V and 10KV/400V, used for rated voltage 380V load. Simply put, a dry-type transformer refers to a transformer in which the iron core and winding are not immersed in insulating oil.
Dry-type transformers are generally divided into two types: on-load voltage regulation and off-load voltage regulation, dry-type transformers with casings and dry-type transformers without casings. Dry-type transformers have no oil, so there are no problems such as fire, explosion, and pollution. Therefore, electrical specifications, Regulations, etc. do not require dry-type transformers to be placed in separate rooms. Losses and noise are reduced to new levels, bringing transformers and low-voltage screens to the same level.
