Overview
YBW35kV environment-friendly combined substation is a complete set of products integrating voltage switchgear, transformer and low-voltage distribution equipment. As a power transformation and distribution equipment in urban buildings, living quarters, medium-sized factories, mines and oil fields, it has the characteristics of strong package, small size, compact structure, high reliability, small field installation workload, short installation period, and portability, etc. It can change its appearance and color appropriately to adapt to the environment and beautify the environment. It is a substitute product of urban and rural civil power transformation and distribution stations and a new complete set of equipment for urban network construction and reconstruction.
Model and meaning
Use environmental conditions
◇ Altitude: ≤ 1000m;
◇ Ambient temperature: +40℃ -25℃ ;
◇ Relative humidity: Daily average ≤ 95%, monthly average ≤ 90%;
◇ Abnormal severe vibration or impact;
◇ Environment for installation: mdoor, no fire or explosion danger, no corrosive gas or d ust, no sharp impact.
Nole: Please negotiate with us if your product is used beyond the range of above conditions.
Structural features
1. The substation consists of high voltage switch room, low voltage switch room, relay protection room and transformer room. The shells of highvoltage switch room, low-voltage switch room and relay protection room can be made of aluminum alloy plate, steel plate or composite plate. The surface of aluminum alloy plate is anodized, which enhances the corrosion resistance of aluminum alloy plate. Steel plates and steel structures are all treated by phosphating, and the composite plate has the characteristics of bright color, beautiful appearance, heat insulation and flame retardance. The transformer room is not provided with a closed shell structure, but is provided with a safety net cover, which is beneficial to ventilation and heat dissipation of the transformer and can ensure personal and equipment safety.
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 10kV at low voltage side, the LV switch compartment can be mounted with XGN2-10,KZNI-12 switchgear, HXGNII-10F,HXGN26-(10F)Ring main unit.
b.when it is 0.4kV 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 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.
5. Refer to the plan layout and vertical plane layout of transformer of 35KV.
Installation
◇ This type of combined transformer substation only requires reinforced concrete foundation outdoor
◇ Transformer compartment 、35 kV switch compartment, 10 kV or 0.4kV switch compartment are all individual output units and are assembled on site, inlet and outlet of power supply.
◇ Inlet and outlet of power supply have overhead and cable two modes for selecting please select according to requirements and give clear indication when placing the order.
Transportation and storage
When the combined type transformer substation is (shipped), it should be divided into several parts for easy transportation. If it has been equipped with SF6 circuit breaker, please discharge it to zero pressure gauge before disconnect.This product should be stored in draughty area free from corrosive gas.
