YBM22-12/0.4 Outdoor Prefabricated Substation (EU)

Rating:
Rated voltage: HV equipment 7.2KV and 12KV, LV equipment 0.4 KV. Rated current: HV equipment 630A, LV equipment 100- 2000A. Application: YBM22 series substation is a kind of compact power distribution device that integrates high and low voltage electrical equipment. It can be used in high-rise buildings, buildings in urban and rural areas, residential communities, high-tech development areas, small and medium size factories, mining areas, oilfields, temporary features sites, and other premises. lt also can be used for acceptance and distribution of power in power distribution system of 6-15KV, 50HZ(60HZ), ring main power distribution system and double power supply or radiate terminal power distribution system.
Feature:
High integrity, small size, compact structure, safe and reliable operation, convenient maintenance, portable, etc. Compared with conventional civil engineering substation, in the same capacity, the prefabricated combined substation need only 1/10~1/15 floor area, so that the features expense is reduced.
Standard: IEC1330

Features

1. The product is connected together by high voltage power distribution equipment,transformer and low voltage power distribution device. And divided into three functional compartments, that is High voltage compartment, Power transformer compartment and Low voltage compartment, have completely HV, LV function.High voltage side of a power supply system, can be arranged in a ring network power supply, end user power supply, dual power supply and other power supply, also can be provided with the high-voltage metering device to meet high voltage measurement. Transformer room can choose S9, SC and other series of low loss of oil immersed transformer or dry type transformer; low voltage chamber can be panel or cabinet mounted structure based on user requirement to form the power supply scheme required by user. These are power distribution,lighting distribution, Static Var Compensator, energy metering and energy measurement and other function, to meet different requirement of user. This make Power management convenient for users and improve the quality of power supply.
2. The high voltage chamber with compact and reasonable structure,has a comprehensive antimis-operation interlock function. It can be equipped with a rail for power transformer when it is required by customer, it can make transformer in and out conveniently in power transformer compartment. Each room has the automatic lighting device, Meanwhile, all elements in high voltage and low voltage cabinet are reliable performance, convenient operation.
3. Adopt natural ventilation and the forced ventilation in two ways.There is ventilation channel for power transformer compartment and High, Low voltage compartment. The exhaust fan is provided with a temperature control device, it can automatic startup and shutdown according to the setting temperature.This ensure the normal operation of transformer.
4. The enclosure structure can prevent rain and dirt. The material adopt color steel plate and have anti-corrosion insulation function.
