Structural features
1. This transformer is made up of Switch compartment, low switch compartment and relay protection compartment and transformer compartment. Enclosures of HV, LV switch compartment and relay protection compartment can be made of aluminum alloy plate, steel plate of composite plate. Aluminum alloy plate is an anodize 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 compartment is arranged with safe guard protecting net but not enclosure, which not only guarantees beer 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 KYN61-33 switchgear or 33KV load switch Aerial cable types available for mounting 33KV inlet wire.
3. LV switch compartment
a. when it is 15Kv at low voltage side, the LV switch compartment can be mounted with XGN2- 415.KZNI-15 switchgear, HXGNII 10F.HXGN26-( 10F)Ring main unit
b.when it is 0.4 kv at LV switch compartment( no preparation of LV switch gear in consideration of space saving) can be series mounted with DW 1sT series, ME series and F 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 bused integrated automatic control system is available on request.
