Dry Type Transformer For Outdoor Installation
Outdoor dry type transformers are one of the common power transmission equipment in power systems. They have the advantages of high efficiency, durability, and low isolation cost, and are widely used in power systems.
However, for outdoor dry-type transformers, safety issues have always been the focus of attention. In order to ensure the normal operation of the transformer and the safety of personnel and property, the following are the safety requirements for outdoor dry-type transformers:
1. Safety requirements of the transformer itself
1.1 The installation of transformers should comply with relevant national and industry regulations and relevant technical standards. At the same time, there should be relatively complete isolation measures to ensure that personnel do not come into direct contact with live equipment.
1.2 The transformer should meet the protection level requirements, including shell damage and cut-off device, etc.
1.3 The transformer bracket should not be deformed or loose, and all fasteners should be checked regularly.
1.4 Transformer equipment should be equipped with complete lightning protection, anti-static and over-voltage protection facilities.
2. Routine maintenance of transformer
2.1 Transformers should be inspected and maintained regularly, and equipment safety hazards should be checked promptly to prevent equipment damage, leakage, and malfunctions.
2.2 Conduct regular insulation strength tests and withstand voltage tests to ensure that the insulation of the equipment is in good condition.
2.3 Always keep the transformer and the surrounding ground clean, and remove dust regularly.
2.4 Regularly check whether the connectors at the transformer junction box, grounding system, controller, thermometer and other connections are complete and the contacts are reliable.
3. Safety requirements of power systems
3.1 The transformer should be disconnected from the power supply before it can be shut down for maintenance. After maintenance, it should be inspected before connecting to the power supply to ensure the safety of the equipment.
3.2 Maintenance personnel should be certified to work and strictly abide by operating procedures and safe operating specifications to ensure a safe and reliable operation process.
3.3 Regularly arrange personnel to conduct inspections or spot checks on the equipment, and deal with hidden dangers in a timely manner to ensure long-term stable, safe and efficient operation of the equipment.
To sum up, the safety requirements for outdoor dry-type transformers involve the safety requirements of the transformer itself, routine maintenance and the safety requirements of the power system. Only by strictly complying with regulations and standards can the normal operation of the transformer be ensured and the safety of personnel and property be ensured.
