Installation environmental requirements for dry type cast resin transformers
Dry type cast resin transformers hold a pivotal and widely recognized role in the global power industry, emerging as the preferred power supply core for critical facilities such as large enterprises, manufacturing plants, hospitals, and educational campuses. Leveraging air convection for cooling, these transformers are indispensable in lighting systems and electronic circuits, while also serving as key components in power systems—including steam turbine transformers, boiler transformers, ash removal transformers, dust collection transformers, and desulfurization transformers. Their adoption is particularly prominent in major and medium-sized cities, accounting for approximately 15% to 20% of the local transformer market share.
Key Safety Precautions for Installation
To mitigate unnecessary faults or accidents during the installation process, strict safety protocols must be strictly observed:
- Construction personnel must wear safety helmets correctly when entering the work site and are prohibited from accessing the area after consuming alcohol.
- During the transportation of transformer equipment, vehicles must be securely fastened with jute ropes to ensure stability, and mixed transportation of personnel and equipment is strictly forbidden.
- All construction tools and equipment used by on-site personnel must undergo thorough inspections and be certified as safe and qualified before use; unqualified equipment is prohibited from being put into operation.
- After the transformer installation is completed, the doors and windows of the power distribution room must be closed and locked securely to prevent unauthorized access or external interference.
Operating Environment Requirements
The safe and reliable operation of dry type cast resin transformers relies heavily on meeting specific environmental conditions. The detailed requirements for their operating environment are as follows:
- Temperature and humidity: Operating temperature ranges from 0°C to 40°C, with a maximum relative humidity of 80%.
- Altitude limitation: The installation site should not exceed 2500 meters above sea level.
- Environmental protection: The transformer must be shielded from rain, moisture, extreme heat, and direct sunlight. A minimum clearance of 40cm must be maintained between its cooling vents and surrounding objects to ensure unobstructed air circulation.
- Contamination avoidance: Avoid operating in environments where corrosive liquids, harmful gases, excessive dust, conductive fibers, or metal particles are present.
- Stability requirements: Prevent installation and operation in locations prone to vibration or strong electromagnetic interference.
- Handling and storage: Prohibit long-term storage or transportation in an inverted position, and avoid severe impacts during loading, unloading, and transportation to protect internal components.
