YBW 33kV Environmentally Friendly Combined Substation

Description

Overview
YBW 33kV Combined type transformer substation is a kind of complete set product integrating voltage switch equipmentand transformer with LV distribution equipment. It is usually applied to civic architec-tures.
Residential districts,mid-size and small-size factories, mine and oil fields, used as tran-sformation and distribution equipment,with characteristics of strong completeness, compact struct-ure, high.
Reliability, low on-site workload, shortinstallation period, movability, etc. In addition, its color and exterior can be changed appropriately to adaptto the surroundings and beautifythe environment.
It really is the ideal successor of current urban and ruralcivil engineering transformer substation, and also is a new type complete set equipment for urban network construction and reformation.

YBW33KV Structural features
This transformer substation is made up of HV swich compartment, LV switch compartment, relay protection compartment and transformer compartment. Enclosures of HV switch compartment, LV switch compartment and relay protection compartment can be made of aluminum alloy plate, steel plate of composite plate. Aluminum alloy plate is anodic oxidation treated to strengthen its corrosion 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 compartm-ent is arranged with safeguard protecting net but not enclosed enclosure, which notonly gua-rantees better thermal diffusivity, but also is able to insure person and equipment against accident.
HV switch compartment The HV switch compartment can be mounted with JYNI-33, KYNI0-33 switchgear or 33kV load switch. Aerial cable type is available formounting 33kV inletand outlet wire.

LV switch compartment
◆ When it is 10KV at LV side, the LV switch compartment can be mounted with XGN2-10, KZNI-12 and KYNI-12 swichgear, HXGNII-10F, HXGN26-10(F) Ring mainunit
◆ When it is 0.4KV at LV side, the LV switch compartment (no preparation of LV switchgear in consideration of space saving) can be mounted with DW15T series, MEseries, M series and F series frame type circuit breaker as well as DZ20 series, CM series, H series and S series molded case air circuit breaker.
Power-off protection compartment The power-off protection compartment is mounted with AC panel, DC panel, signal panel, protection pandel, 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 integreted automatic control system is available on request.
