NKVSD underground tank substation/landscape semi-buried tank substation is a new type of landscape tank substation , the underground tank substation covers only 30% of the traditional tank substation, and the noise and electromagnetic radiation are low.
In downtown areas, real estate communities, and industrial parks, it is not difficult to find tank-type substations that not only occupy the golden ground of downtown areas, but also are scattered and disorderly. Perhaps because of the environmental beautification, the commonplace tank substation really looks a bit lame in the new frame of reference.
With the development of urban construction, landscape buried tank transformers have emerged.
The underground tank transformer is composed of underground combined transformer, fully insulated and fully sealed compact high-voltage cabinet, outdoor high-voltage cabinet, outdoor low-voltage cabinet, and light tank type low-voltage protection shell, which is a complete set of underground substation and distribution equipment pre-assembled in the factory, and can also be added according to user needs to add light tank-type cable branch tank and light tank -type high-voltage metering.
The protection level of the buried tank transformer can reach IP68, which can ensure that it can operate safely for a period of time under water, but this is only temporary, and it needs to be treated for drainage to operate for a long time. For areas with low groundwater level, a prefabricated pit structure is adopted, and the vent at the top of the pit has good ventilation and rainproof ability, and the bottom of the pit is paved with water sand and pebbles, and water can directly seep into the ground; If it is an area with a high water level, then a one-and-done solution is to make a fully enclosed concrete structure to completely prevent the infiltration of surface water. It is recommended to increase NKTEVA6 monitoring whether the underground transformer is submerged in water and whether the underground transformer is running over temperature.
The underground landscape tank transformer can be built-in intelligent temperature visualization, distributed red array monitoring and detector NKTEVA6 cable flood alarm is equipped with software
The new version adds the flood alarm function (with water immersion sensor), the red array field of view angle is 90 degrees, and the field of view is wide
It is very suitable for tank transformers/high and low voltage cabinets/energy storage battery cabinets/data center switchgear/internal monitoring, as well as cable tunnel comprehensive pipe gallery fire and fire monitoring
Through the NKTEVA6 built into the tank or cabinet body, the power cable and wire joints in the cabinet can be monitored in real time to determine whether they are loose.
It can also monitor whether the transformer is running over-temperature in real time and whether the temperature of the energy storage battery is over-temperature, and check and determine the switch position
You can watch temperature videos and videos in real time, and you can also apply NKTEVA6 for electrical engineering inspection and acceptance
Under normal circumstances, after the completion of the transformer switchgear distribution tank project, it is necessary to carry out acceptance electrical tests, such as insulation tests, withstand voltage tests, overcurrent protection tests, etc., but for the cable and wire joints of these projects are loose and heated, the above tests may not be tested. This is due to the fact that the contact resistance of the poor contact joint is relatively large, and most of the energy is lost at the poor contact joint, even when the operating current is relatively small, it will heat abnormally, and even the heating temperature is relatively high. As the owner, you can apply NKTEVA6 for electrical engineering inspection and acceptance.
