Summary

YB□-40.5 The series of prefabricated box type substations are pre fabricated and assembled in the factory, including transformer, high voltage Bay and control equipment, low voltage Bay and control equipment, internal wiring, metering, compensation, arrester and other auxiliary equipment in a common enclosure or a group of enclosures, A complete set of substation which has passed the type test is a new equipment for urban and rural substation transformation. It is widely used in urban street lighting, green areas, high-rise buildings, commercial centers, residential areas, villages, factories and railways.

Widely used in urban network construction, it is a power distribution device to replace building power distribution room and post transformer.

Model meaning

Normal use environment

⦿ altitude: no more than 1000m (above this altitude, it needs to be negotiated with the company);

⦿ ambient temperature: high temperature + 40C, low temperature - 25C;

⦿ humidity: the average daily relative humidity is not more than 95%, and the average monthly relative humidity is not more than 90%;

⦿ wind speed: outdoor wind pressure shall not exceed 700pa (34m / s);

⦿ shockproof: the horizontal acceleration is not more than 3m / s', and the vertical acceleration is 1.5 m / S3;

⦿ inclination of installation site: no more than 3 degrees;

⦿ installation environment: the surrounding air is not obviously polluted by corrosive and combustible gases, and there is no violent vibration at the installation site;

⦿ in case of exceeding the above conditions, it can be decided through negotiation with the company.

Structural holding point

1. The internal configuration is reliable and economical. The high voltage side is equipped with load switch + fuse, which can reliably protect the transformer. The low voltage side is equipped with SOCOMEC isolating switch, high breaking capacity fuse, and a 2kma station transformer can be installed. The main circuit scheme is simple and economical

2. The high-voltage load switch and high-voltage fuse are placed in the fully sealed transformer oil tank. The transformer oil is used as the insulation medium, and the high-voltage outlet end adopts the fully insulated green silicone rubber cable connector. It is truly full working condition, fully insulated, fully sealed and maintenance free, and can guarantee the full service life of 20 years in harsh environment.

3. The high burning point oil is used as insulation and cooling medium, so there is no need to filter or change oil in the service life. The sealing element adopts high-performance ball, which has the same service life as the equipment.

4. The outer door of the box adopts labyrinth sealing method, equipped with high elastic and long-life sealant strip, and the ventilation holes are equipped with dust-proof facilities, which can effectively prevent the erosion of wind turbine caused by sand, rain and snow, and the protection grade is IP44
