Q: Do dry type transformers produce noise during operation?
A: Dry Type Transformers are known for their quiet operation compared to some oil-filled transformers. The absence of cooling fans and pumps contributes to reduced noise levels.
Q: What are the key differences between VPI (vacuum pressure impregnation) and cast resin dry type transformers?
A: VPI transformers are vacuum impregnated with epoxy resin, while cast resin transformers are cast with epoxy resin. VPI transformers are generally more compact, but cast resin transformers offer better protection against environmental factors.
Q: Can dry type transformers be retrofitted into existing systems?
A: Yes, Dry Type Transformers can be retrofitted into existing systems, but it requires careful planning and may involve modifications to the electrical infrastructure. Consulting with a qualified professional is essential.
Q: How do you size a dry type transformer for a specific application?
A: Sizing a Dry Type Transformer involves considering factors such as the load requirements, voltage levels, and environmental conditions. Consulting with a qualified engineer is recommended to ensure proper sizing.
Q: Are there any size limitations for dry type transformers?
A: Dry Type Transformers are available in various sizes to accommodate different power ratings. However, for very high power applications, other types of transformers may be more suitable.
Q: Can dry type transformers be overloaded?
A: While transformers are designed to handle overloads for a short duration, continuous overloading can lead to overheating and damage. It is important to operate Dry Type Transformers within their specified load capacity.
Q: What are the temperature limitations of dry type transformers?
A: Dry Type Transformers are designed to operate within specific temperature limits. It is crucial to adhere to these limits to prevent overheating and ensure the transformer's reliable performance.
Q: How do dry type transformers contribute to environmental sustainability?
A: Dry Type Transformers do not contain oil, which eliminates the risk of oil spills and reduces environmental impact. They are considered more environmentally friendly and align with green building practices.
Q: What is the reason for the abnormal noise of dry-type transformer? How to solve it?
A: First of all, we need to determine where the abnormal noise occurs. There are five common abnormal noises, namely 1. The core excitation sound is high. This may be due to overvoltage or load. Thyristors and other components are used. Solution: Change the tap position. 2. Vibration or resonance sound. Possible cause: unstable installation or resonance Solution: Tighten the bolts, stabilize, eliminate the resonance conditions, one side is too close to the concrete wall, or resonate with other equipment, 3. Mechanical vibration sound of the core Possible cause: This problem is actually not easy to judge, and experience is required Solution: Tighten the bolts and clamp the core 4. There is a discharge sound in the dry-type transformer Possible cause: poor grounding or corona Handling: Improve grounding and find out the cause of corona 5. The accessory sound is abnormal and there is vibration Possible cause: abnormal fan
Q: Can dry type transformers be installed outdoors?
A: Dry Type Transformers are primarily designed for indoor use. If outdoor installation is necessary, they should be housed in weatherproof enclosures to protect them from environmental elements.
Q: Do dry type transformers require regular maintenance?
A: While Dry Type Transformers generally require less maintenance compared to oil-filled transformers, routine inspections are recommended. Checking for loose connections, cleaning, and ensuring proper ventilation are part of regular maintenance.
Q: In what applications are dry type transformers commonly used?
A: Dry Type Transformers are preferred in applications where safety, environmental concerns, and space constraints are crucial. They are commonly used in buildings, underground substations, and industrial facilities.
