European Style Box Transformer

The skeleton structure of the substation is made of channel steel and angle steel, which has reliable mechanical strength. The outer shell can provide various metal, stainless steel, and non-metallic boxes according to the different usage occasions of users. The product is beautiful and elegant, and environmentally friendly. And it has good anti-corrosion performance. Each room in the substation is separated into independent compartments by partitions.

The top cover is a double-layer structure to prevent thermal radiation. The top of the transformer is equipped with an exhaust fan, which automatically controls the temperature of the transformer room, increasing air convection and reducing room temperature. The rotatable connection parts of the substation are sealed with rubber tape, which has good moisture resistance.

Summary

1. The outdoor box type substation is composed of high-voltage distribution devices, transformer and low-voltage distribution devices connected, divided into three functional compartments (high-voltage room, transformer room, and low-voltage room), with complete functions for the high and low voltage rooms. There are multiple power supply methods for the high-voltage side, and high-voltage measuring elements can also be installed to meet the requirements of high-voltage measurement. The transformer room can choose S7, S9, as well as other low loss and oil consuming diffuse and dry transformers; The transformer room is equipped with a self starting forced air cooling system and lighting system. The low-voltage room can adopt a fixed or assembled structure according to user requirements to form the power supply scheme required by the user. It has multiple functions such as power distribution, lighting distribution, reactive power compensation, electricity metering, and quantity measurement, meeting the different requirements of users, and facilitating user power supply management and improving power supply quality.

2. The high-voltage chamber has a compact and reasonable structure, and has a comprehensive anti misoperation interlocking function. When requested by the user, the transformer can be equipped with tracks to facilitate entry and exit from the doors on both sides of the pressure chamber. Each room is equipped with automatic lighting devices. In addition, all components selected for the high and low voltage rooms have reliable performance, convenient operation, and ensure safe and reliable product operation, as well as convenient operation and maintenance.

3. Use natural ventilation and forced ventilation to ensure good ventilation and cooling. Both the transformer room and low-voltage room have ventilation ducts, and the exhaust air is equipped with temperature control devices, which can automatically start and close according to the set temperature to ensure the full load operation of the transformer.

4. The box structure is made of channel steel and angles, which have strong mechanical strength. The outer shell is made of aluminum alloy insulation composite plates, non plates, or non-metallic materials. The surface is smooth and flat, and the product is beautiful and generous, and has good insulation effect and strong anti-corrosion performance. Each room is separated into independent compartments by partitions, and each compartment is equipped with lighting devices that are controlled by doors to open and close. The top of the transformer room is equipped with an exhaust fan, which automatically controls the temperature of the transformer and increases air convection to lower the room temperature. The rotatable connection parts of the substation are sealed with tape and have strong moisture-proof ability. Our company has a complete set of provincial-level certified drawings and data, which are all computerized and stored in the computer. If a standard solution is used, it can be efficiently and high-quality to complete the design task as long as it is simply called. If it is not standard, we can quickly design CAD drawings that meet user requirements in strict accordance with the ISO9001 quality system requirements according to user requirements.

5. As an important power supply unit in the cabled distribution network, this product is a pre installed product integrating high-voltage control, protection, power transformation and power distribution equipment. It is used for 502 three-phase AC, and the rated capacity of the transformer is up to 1600KVA. Widely used in residential areas, factories and mining enterprises, hotels, hospitals, parks, oil fields, airports, docks, railways, temporary facilities, and outdoor power supply places.

6. This equipment meets the requirements of the national standard GB3906 "3-35kV AC Metal Enclosed Switchgear" and the national standard IEC298.

Precautions for lifting and transportation, use and installation:

1、 The Earth electrode shall be embedded around the foundation of the box type station. The transformer and lightning protection grounding can be used together, and its grounding resistance R<4Q

2、 Special lifting tools should be used for lifting box stations, and the lifting part must follow the marked position of the box station

3、 The junction between the lower part of the box station and the foundation needs to be sealed with cement slurry to prevent water from entering the cable room.

4、 After the cable enters the sleeve, its gap must be sealed to prevent insects and water from entering. IV

5、Before the box station is put into operation, the following conditions must be checked:

1. The junction between the lower part of the box type substation and the foundation must be horizontal. If there is jamming when opening each door, this is because the foundation plane is uneven, and the junction level between the box type substation and the foundation surface must be adjusted.

2. Adjustment method: Fill thin iron sheets at the lower part of the box substation and the foundation joint courtyard until the doors of each room can be opened flexibly.

3. After the assembly of the entire machine is completed, attention must be paid to the integration of the box body and the distance between the front and rear of the vehicle when loading and shipping, to prevent the vehicle from being hit back and forth due to braking during driving. At the same time, the box type station low frame and the vehicle low frame must be welded firmly with electric welding, and then the bottom frame and the vehicle bottom must be twisted tightly with steel wire, and the assembly cable should be tightened several times from the top cover to the lower part of the vehicle. All places where ropes are tied must be padded with cardboard or other soft objects to prevent damage to the coating surface.

4. To keep the box station in good condition during operation, it is best to clean and wipe the interior and exterior once every six months or a year after a power outage.

5. If it is found that the outer surface of the box is dirty during transportation after installation, it can be wiped with detergent and rinsed with clean water.
