Structure of European style box transformer

In China, European style box type substations are commonly used, with three parts each consisting of one room, forming a "mu" or "pin" structure. Commonly used models include ZBW and XWB. The cross-sectional and wiring diagrams are shown in Figure GYPD00102003-1. The high voltage chamber of the European style box transformer is a ring network, double line or terminal unit load switch, with a small volume and compatibility with the ring network cabinet. Adopting a safe and reliable compact design, with comprehensive anti misoperation interlocking function, high reliability, and convenient operation and maintenance. High voltage equipment generally adopts a combination of load switch and fuse. The fuse is equipped with an impactor. After the fuse is blown, the striker will push the release mechanism, and the load switch three-phase will jump open at the same time to avoid phase loss operation. At the same time, if an electric operating mechanism is used, distribution automation function can be implemented. The 10kV cable outlet of the ring network structure is equipped with a ground fault indicator and zero sequence sensor. Transformers can be oil immersed or dry type, with D, yn11 wiring. Considering unfavorable heat dissipation, natural ventilation or top forced ventilation can be used. The low-voltage room is equipped with metering and reactive power compensation, and the secondary circuit and number of outgoing lines can be designed according to user needs to meet different needs. The outer shell is made of steel plate or alloy plate, with a double-layer top cover and good insulation. The appearance and color can be coordinated with the environment. The high-voltage chamber, transformer chamber, and low-voltage chamber are separated into independent compartments by partitions. For monitoring and maintenance, lighting devices are installed in each compartment, and the lighting switch is controlled by the door

Operation of Box Substation

1. The box type substation should be placed at a relatively high place, not in low-lying areas, to prevent rainwater from entering the box and affecting equipment operation. When pouring concrete platforms, gaps should be left on the high and low voltage sides to facilitate the laying of cables in and out. When excavating the foundation, if encountering the ground formed by the accumulation of garbage or corrosive soil, it must be excavated to solid soil, then backfilled with good soil quality and compacted, and then filled with three layers of soil or gravel to ensure the stability of the foundation.

2. The grounding and neutral connection of the box type substation share a common grounding network. The grounding grid generally adopts the method of driving grounding piles at the four corners of the foundation, and then connecting them as a whole. There must be two reliable connections between the box type substation and the grounding grid. After operation, the grounding connection should be checked regularly to ensure it is not loose or corroded. Regularly measure the grounding resistance, not exceeding 4 Ω.

3. The box type substation mainly adopts natural air circulation cooling. Therefore, debris should not be piled up around it, especially the transformer room door. Louver ventilation holes should also be regularly removed to ensure that the equipment does not exceed the maximum allowable temperature.

After the low-voltage circuit breaker trips, the cause should be identified before power can be transmitted to prevent the accident from expanding.

5. The high-voltage chamber of the box type substation should be equipped with zinc oxide lightning arresters, and the installation method should be convenient for testing and replacement.

6. Equipment such as ring network switches, transformers, lightning arresters, etc. in the high-voltage room should be regularly inspected and maintained, defects should be discovered and dealt with in a timely manner, and insulation preventive tests should be conducted regularly. If it is discontinued for more than 3 months and is put into operation again, a full project preventive test should be conducted.

7. To replace a high-voltage fuse without breaking capacity, the transformer must be powered off, and the mechanical interlock must be properly released during operation, and an insulated operating rod must be used.

8. All incoming and outgoing cable holes of the box type substation should be sealed to prevent small animals from entering and causing accidents.

9. Must have a warning sign of "high voltage danger" and a nameplate number for electrical equipment
