The substationis suitable for residential quarters, urban public transformers, bustling downtowns, construction power supplies, etc. Users can choose box-type transformers according to different usage conditions and load levels. Since its inception, substation has developed extremely rapidly. It has accounted for 70% of distribution transformers in developed countries in Europe and 90% in the United States. The continuous renewal and transformation of urban power distribution networks will surely be widely used.
What should we notice when using the substation?
In which of the following situations, substation should be shut down immediately?
Why is the appearance of Compact substation chosen by consumers?
When the substation pressure release device generates extraordinary pressure during operation, the release device is automatically released. After the pressure of the fuel tank is normal, the valve cover of the release device should be automatically closed. If the release is activated, the valve cover will push up the indicator rod and must be manually reset. At this time, the micro switch is activated, and the wrench must be moved to reset the machine in preparation for the next action to send a signal. The release contact should act on the signal.
a. The internal sound of the substation is loud and uneven, accompanied by cracks and electric shocks.
b. The oil temperature exceeds 105 degrees.
c. When the load and cooling device are normal, the temperature rises abnormally quickly.
d. The substation leaked severely and the oil level dropped sharply.
e. The pressure release of the substation sends out a signal.
f. The casing of the substation has serious cracks, damage and discharge.
The shell of Compact substationadopts aluminum-zinc steel plate and container manufacturing technology. The appearance design is beautiful. Under the premise of ensuring the reliability of power supply, by choosing the shell color of Compact substation, it is very easy to harmonize with the surrounding environment. It is especially suitable for urban construction, such as : Urban residential quarters, stations, ports, airports, parks, green belts and other densely populated areas, it can be used as a fixed substation, but also as a mobile substation, with the role of embellishment and beautification of the environment.
The shell of the Compact substationis made of steel or alloy plate, equipped with a double-layer top cover, which has good heat insulation. The shell and frame are all treated with anti-corrosion treatment, which is suitable for long-term outdoor use. The shape and color can be coordinated with the environment. The installation is convenient. There is a cable room under the foundation of the Compact substation, and a manhole is provided in the low-voltage room to enter the cable room for work. In terms of volume, the European-style box substation has a larger product volume due to the internal installation of conventional switch cabinets and transformers. The American box substation has a small volume due to the integrated installation.
