Safety Design Oil Cooled Power Transformer Installation

There are many problems that need to be paid attention to in the process of installation and design of oil-immersed transformers, especially the installation and design specifications must be mastered, so that oil-immersed transformers can be safer and have greater safety performance. play out. The safety performance of oil-immersed transformer installation is more important, and the installation design is also more important. So what problems should we pay attention to in the process of installation and design? What steps should we go through? Lets take a detailed look together:

1. The temporary power supply system adopts the TN-S power supply system, which is a power supply system that strictly separates the working neutral line N and the special protection line PE at the main power supply, also known as the three-phase five-wire system. The PE line is specially used to carry the fault current to ensure the operation of the device.

2. To set up a leakage protector, adhere to the principle of three-level protection and one machine, one gate, and one leak, one box. The rated leakage current of the leakage protector in the switch box next to the equipment should not be greater than 30mA, and the leakage action time should not be less than 0.1S.

3. In special occasions, use the power supply of the corresponding safety level according to the relevant requirements. The safety voltage refers to the voltage that does not wear any protective equipment and does not cause damage to various parts of the human body when touched.

4. The manufacture, installation and protection of electrical equipment, installation location, power distribution classification, wire selection and wiring, and wiring requirements must comply with the electrical specifications.

5. A perfect system should also be established in the construction preparation stage:

5.1 Establish construction organization design and technical measures for safe electricity use.

5.2 Establish a technical disclosure system.

5.3 Establish a safety inspection system.

5.4 Establish an electrical maintenance system.

5.5 Establish a project demolition system.

5.6 Establish a safety inspection and evaluation system.

5.7 Establish a responsibility system for electricity safety.

The steps and methods to be paid attention to in the process of installation and design of oil-immersed transformers are also of concern to everyone.
