Product Description
Combined type of transformer substation is a kind of complete set product integrating voltage switch equipment and transformer with LV distribution equipment.
It is usually applied to civic architectures, residential districts, factories, mine and oil fields used as transformer and distribution equipment with characteristics of strong completeness and compact structure, high reliability, short installation period, movability etc.
In addition, it's color and exterior can be changed appropriately to adapt to the surroundings and friendly to the environment.
Features
1 - Made up of HV switch compartment, LV switch compartment, relay protection compartment and transformer compartment. Enclosed of HV, LV compartment and relay protection compartment can be made of aluminum alloy plate, steel plate of composite plate.
Aluminum alloy plate is an anodic oxidation treated to strengthen its corrosions stability. Steel plate and steel structured parts are all phosphating treated and the composite plate is featured with vivid appearance, heat insulation and fire retardation.
The transformer compartment is arranged with safe guard protecting net but no enclosure, which not only guarantees better thermal diffusivity but also is able to insure person and equipment against accident.
2 - HV switch compartment: The HV switch compartment can be mounted with 35KV switchgear or load switch Aerial cable type available for mounting 35KV inlet wire.
3 - LV switch compartment: When LV side is 10KV, LV switch compartment can be mounted with 10KV and 12KV switchgear ,10KV RMU
4 - Power off protection compartment: The power off protection compartment is mounted with AC panel, DC panel, signal panel, protection panel, motion control panel (RTU), carrier wave machine panel or optical fiber termination set.
Note: This transformer substation can adopt general relay protection, also microcomputer based integrated automatic control system is available on request.
5 - Refer to the plan layout and vertical plane layout of 35KV transformer.
Fields of application
1 - Ambient air temperature: -25°C - +40°C
2 - Altitude: ≤1000m
3 - Relative humidity: daily≤95%, monthly ≤90%
4 - Installation site should be free of fire, explosive danger, serious pollution, chemical corrosion or severe vibration.
