What are the inspection contents of the transformer

1) Observe the oil level of the transformer: The oil in the oil-immersed transformer plays the role of cooling and insulation, and the oil level is although the temperature changes, so the transformer is engraved with the corresponding oil level at different temperatures, when the oil level is found to be too low, the temperature of the transformer should be measured and compared, and the transformer body should be carefully observed whether there is oil leakage, if the closed transformer should lift the air relief valve to check whether it is false oil level.

The significance and precautions of measuring the DC resistance of transformer windings

Measuring the DC resistance of the transformer winding and the bushing can check the welding quality of the wire joint inside the winding, the welding quality of the lead and the winding joint, the tap position of the voltage tap changer and the contact between the lead and the bushing is good, the connection of the parallel branch is correct, the current carrying part of the transformer is short circuit and the winding is short circuit.

The automation road of electronic transformer inductor enterprise is discussed

In the early days of reform and opening up, the Yangtze River Delta and Pearl River Delta became the residence of almost all well-known labor-intensive enterprises in the world in a short period of time. Workers from all over the country flocked here to look for work, and the relative surplus labor resources at that time greatly met the initiative of enterprises to choose.

The silver snake has passed away from the cold wind, and the Pegasus welcomes the spring. Happy New Year!

Today we are gathered together to celebrate the Spring Festival, in this happy and peaceful, full of hope of the beautiful moment, my company again to the vast number of new and old friends and the company's staff to extend sincere greetings and heartfelt wishes!

Painted boxes change some knowledge points

With the development of cities, people pay more and more attention to the appearance of cities. There are many box-type substations on city streets, some of which may not be compatible with urban greening. Municipal authorities are constantly trying to transform these infrastructures of the city with new technologies, and through the painted box transformed shell, practicality and aesthetics are combined to create a more beautiful urban landscape.

What are the benefits of painted boxes

In order to enhance the image of the city and highlight the city culture, many government departments will show the unique charm of the city through painted boxes. Using pictures is more impressive than simply writing slogans. Whether it is the picturesque Chinese style, or the hip hop cartoon animation, it will give people a refreshing feeling. Painted boxes can enhance the vitality of the city and show the uniqueness of the city.

Rectifier circuit requirements for intermediate frequency power supply

The load of the rectifier circuit of the intermediate frequency power supply is the inverter, and the output active power of the inverter is provided by the rectifier circuit, and the DC output voltage of the rectifier circuit is required to be continuously smooth and adjustable (0-513v) within the specified range. If the load of the power supply varies greatly, the rectifier circuit should automatically limit the output voltage. Usually, the current and voltage signals are taken out at the load end to change the rectifier phase shift control Angle to complete the cut-off and voltage cut-off.

Future China's power generation and transmission and distribution technology roadmap

The stable supply of electricity in our country mainly relies on thermal power generation and hydroelectric power generation. The power grid supports the safe transmission of power, the balance of power and the reliable use of users. Excellent power generation and transmission and distribution technology is an important basis to ensure the healthy and sustainable development of China's power industry.

Improve the level of distribution automation to lay the foundation for smart grid development

One of the keys to the development of new energy in China is grid-connected power generation, and one of the landing points of grid-connected power is smart grid. Although the curtain of the construction of a strong smart grid has been opened, it is not a matter of overnight to realize the informatization, automation and interaction of the power grid. The construction of smart grid involves the access technology of new energy
