Professional Compact Electrical Distribution Substation Equipment 3 Phase

Product description

Box type substation is a compact complete set of distribution equipment that combines high-voltage switchgear, distribution transformer and low-voltage switchgear according to certain wiring scheme. Main components: transformer, high-voltage switchgear and its control equipment, low-voltage switchgear and its control equipment, corresponding internal connecting wire (cable, busbar, etc.) and other auxiliary equipment.

Distribution system to act as a small capacity independent substation. When acting as 6-24 / 0.4KV step-down station, the general capacity of it is below 1250KV, which is suitable for factories, mines, ports, stations, residential quarters and underground facilities and other places. It has advantages of small area and flexible movement, which can go deep into the load center and adjust the radius of power supply and save energy. So it is popular with users.

Use condition

1. The maximum ambient air temperature shall not exceed 45℃, and the minimum shall not exceed - 45℃;

2. The altitude shall not exceed 1000m. If special customized transformers and low-voltage components are used, the altitude can reach 4000m;

3. It shall be placed in a place with a vertical inclination of no more than 5°and no severe vibration or impact;

4. The air humidity is not more than 90% (+ 25℃);

5. Gas place without conducting dust, explosion hazard, corrosion metal and electrical components;

6. Outdoor wind speed shall not exceed 35m/s.

7. If the above normal use environment conditions are exceeded, the customer can customize it with our company.

Structure characteristic

1. The box shell is designed according to the actual situation with reference to foreign advanced technology, and it has the characteristics of firmness, heat insulation and ventilation, stable performance, corrosion prevention, dust prevention, waterproof, small animal prevention, beautiful appearance, etc. There are many choices of shell materials, such as steel plate, composite plate, stainless steel plate, cement plate, etc.

2. There are high-voltage switchgear such as xgn15, hxgn17 or kyn28a and other equipment in the high-voltage room for high-voltage incoming line, high-voltage metering and high-voltage outgoing line. The high-voltage side can be arranged with ring network power supply, terminal power supply, dual power supply and other power supply modes, and high-voltage metering elements can also be installed to meet the requirements of high-voltage metering. The main switch is generally load switch or vacuum circuit breaker, with compact and reasonable structure and perfect anti misoperation function.

3. There are low-voltage switchgear such as GGD, GCS or MNS and other equipment in the low-voltage room for low-voltage incoming line, reactive compensation and low-voltage outgoing line. The low-voltage side adopts the panel type or cabinet mounted structure to form the power supply scheme required by the user, which can meet the power distribution, lighting distribution, reactive compensation, electric energy metering and other functions. The main switch generally adopts the universal circuit breaker or the intelligent circuit breaker, which is flexible in installation and simple in operation.

4. The transformer in the transformer room can use the fully sealed oil immersed transformer or dry-type transformer. The oil immersed transformer can be S9, S11, S13 or SH15, and the dry-type transformer can be scb10, scb11, SGB10 or scbh15. According to the actual needs of customers, it can be configured freely, which has the advantages of more selectivity and flexibility.

5. The cover of the box is designed with double-layer structure, and the interlayer is filled with foam plastics, which has good heat insulation function. The transformer room is equipped with anti condensation and automatic temperature control monitoring, heating and cooling devices. A dust-proof device is arranged on the position of the door sheet and the louver outside the side plate.

Note: Due to continuous product improvement, the dimensions provided in this sample are for reference only. If necessary, our company can design and produce according to user requirements. Please contact the company in time.
