Overview of pad mounted transformers

Pad mounted transformer is a power transformer that combines plug-in fuses, backup fuses, tap changers, loop load switches (2/4 circuits), low-voltage distribution devices, and other corresponding auxiliary equipment on the basis of ordinary oil immersed transformers. Rated AC frequency 50Hz/60Hz, maximum working voltage up to 35KV, capacity 75KVA-3000KVA. Padded transformers provide many benefits to users, saving a lot of energy and bringing environmental benefits to owners. Higher efficiency not only extends the lifespan of pad mounted transformers, but also saves costs for owners in the form of lower energy bills and reduced ownership costs.

The main advantages of pad mounted transformers compared to ordinary oil immersed transformers are:

1. Safe and reliable: The pad mounted transformer adopts efficient insulation protection and heat dissipation equipment, and the structure of the cable cabinet is reasonable, which can effectively ensure the safety and reliability of the power equipment. The overload capacity is strong: it allows an overload of 2 times 2 hours, an overload of 1.6 times 7 hours, but does not affect the service life of the pad mounted transformer.
2. Adopting elbow type plug: It can be very convenient for connecting high-voltage incoming cables and can be plugged and unplugged with power.
3. Strong defense ability: Pad mounted transformers have strong defense ability, which can effectively resist instantaneous voltage peaks in power equipment and protect equipment from damage. Adopting dual fuse protection: a. Insert type fuse (BAY-o-NET) is used to protect the secondary side of the box transformer with dual sensitive fuses (temperature and current). 4. Short circuit fault occurs; b. The backup current limiting protection fuse (ELSP) is used to protect the high-voltage side from faults that occur inside the box transformer.
5. Long life: The pad mounted transformers produced by Hengfengyou Electric use high-quality materials and high-tech production processes, which are durable and have a higher service life. The overall service life is higher than that of ordinary oil immersed transformers.
6. Pad mounted transformers are divided into terminal type and ring network type (one transformer can supply power to another transformer at the same time), which is very convenient for conversion, improving power supply distance and reliability.
7. Energy conservation and environmental protection: In the design and use of pad mounted transformers, attention is paid to energy conservation and environmental protection (FR3 environmentally friendly vegetable oil is now commonly used), which can not only ensure high energy efficiency, but also reduce energy waste and environmental pollution.

The main drawbacks of pad mounted transformers compared to ordinary oil immersed transformers are:

The appearance size and weight of power transformers with the same voltage and capacity are larger than those of ordinary oil immersed transformers, and the cost is of course higher than that of ordinary oil immersed transformers.

Application industry and country of pad mounted transformers:

Pad mounted transformers have a wide range of applications due to their high stability and reliability. The pad mounted transformer industry mainly involves transmission, distribution, industry, transportation, aerospace, communication and other fields. General purpose, industrial sites, electrical distribution rooms, basement power distribution, manufacturing facilities, steel plants, offshore oil platform, commercial, military, processing plants, utilities, public places, etc. The main application areas of pad mounted transformers are in North America, South America, Oceania, East Asia, Southeast Asia, and other regions. The main countries include China, the United States, Canada, Japan, Honduras, Venezuela, Dominica, Chile, the Philippines, Australia, and other countries and regions. Hengfengyou Electric has UL certification in the United States and CSA certification in Canada, providing perfect solutions for pad mounted transformers hfy@hengfengyou.com .
