Baoding general installation and commissioning of oil-immersed transformer than everyone can learn, but some powerful baoding oil-immersed transformer oil-immersed transformer because the use of big power, using time is longer, the installation environment is more complex, so the mass of oil-immersed transformer is different from general of oil-immersed transformer, so we have all been to baoding oil-immersed transformer power to inspect, install and debugging. Our company has rich experience in installation and maintenance of oil-immersed transformer with relatively high power. We have summarized the following:

Oil-immersed transformer

1. Unpacking inspection of high-power baoding oil-immersed transformer before power on:

(1) check whether the voltage regulator box body is damaged in the transportation process;

(2) check the voltage regulator on the brand name and product specifications are consistent;

(3) check the panel of the head, indicator light, button, switch, compensation baoding oil transformer, contact regulator and other devices are intact;

(4) check whether the fastener is loose shift each part of the connection wire is loose or poor contact;

(5) check the pressure regulating system, transmission mechanism of the device is safe and reliable, such as carbon brush dislocation or incomplete fracture, should be replaced in a timely manner.

2. Installation environment of high-power baoding oil-immersed transformer:

(1) compensation type voltage regulator should be installed in the dry ventilation, does not affect the insulation of the voltage regulator in the environment;

(2) there should be a certain space around the voltage regulator, for the future debugging, maintenance, maintenance;

(3) the installation site should be free from serious vibration or turbulence.

3. Wiring before commissioning of high-power baoding oil-immersed transformer:

(1) the voltage regulator input power line section should meet the voltage regulator corresponding capacity of the current value;

(2) the input power line should be connected to the input end of the voltage regulator, and according to the bus color: yellow, green, red respectively connected to A phase, B phase, C phase. Can output the power cord in the output of the voltage regulator, and bus bar color: yellow, green, and red respectively after a phase b phase c phase, neutral zero received by zero "N" column, chassis shell with earth connection, grounding resistance should be less than 0.4 M Ω.

(3) double cabinet or multi-cabinet structure of the voltage regulator, the bus between the cabinets must be connected according to the color, other lines should be connected according to the number.
