YBW 35kV Combined type transformer substation
General
Combined type 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, mid-size and small-size factories, mine and oil welds, used as transformer substation and distribution equipment, with characteristics of strong completeness, compact structure, high reliability, low on-site workload, short installation period, movability, etc. In addition, its color and exterior can be changed appropriately to adapt to the surroundings and beautify the environment, it really is the ideal successor of current urban and rural civil engineering transformer substation, and also is a new type complete set equipment for urban network construction and reformation.

Structure character
1. This transformer substation is made up of HV switch 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 phosphate treated, and the composite plate is featured with vivid appearance, heat insulation and re retardation. The transformer compartment is arranged with safeguard protecting net but not enclosed 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 JYNI-35, KYNI0-35 switchgear or 35KV load switch. Aerial cable type is available for mounting 35KV inlet and outlet wire.
3. LV switch compartment
a. When it is 10KV at LV side, the LV switch compartment can be mounted with XGN2-10, KZNI-12 and KYNI-12 switchgear, HXGNII-10F, HXGN26-10(F) Ring main unit
b. 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, ME series, 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.
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.
