Overview

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,  mid- size and  small factories ,  mine and  oil fields used  as transformation  and  distribution  equipment with  characteristics of strong  comple teness and  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 friendly to the environment.it really the idea of success of current urban and rural civil engineering transformers substation, and also is new type complete set equipment for urban network construction and reformation.

Model and meaning

1. Altitude: < 1000m;

2. Ambient temperature: +40*C-25°C ;

3. Relative humidity: Daily average < 95%, monthly average < 90%;

4. Abnormal severe vibration or impact;

5. Environment for installation: Indoors, no fire or explosion danger, no corrosive gas or dust, no sharp impact. Nole: Please negotiate with us if your product is used beyond the range of above conditions.

Structural features

1. This transformer is made up of Switch compartement, low switch compartment and relay protection compartment and transformer compartment. Enclosures of HV, LV switch comp artment 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 not enclosure, which not only guarantees better thermal diffusivity but also is able to insure person and equipm ent against accident

2. HV switch compartment: The HV switch compartment can be mounted with JYNI-35 switchgear or 35KV load switch Aerial cable types available for mounting 35KV inlet wire.

3. LV switch compartment

a. when it is lOKv at low voltage side, the LV switch compartment can be mounted withXGN2-10,KZNI-12 switchgear, HXGNII-10F,HXGN26-( l()F)Ring main unit

b. when it is().4kv at LV switch compartment( no preparation of LV switch gear in consideration of space saving) can be series mounted with DW15T series, ME series and F frame

type circuit breaker as well asDZ2() 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.

5. Refer to the plan layout and vertical plane layout of transformer of 35KV.
