+ Form 3,4 đƣợc dùng khi không gian cho mỗi đơn vị có hạn , vì rất khó thao tác hay bảo trì nếu không ngăn cách các đơn vị , trừ khi phải cắt điện toàn tủ
Như vậy, Form tủ điện có chức năng bảo vệ an toàn và đảm bảo hoạt động liên tục của hệ thống điện Tủ điện có form càng cao thì đáp ứng yêu cầu về an toàn càng lớn, nhưng quá trình thiết kế và sản xuất cũng khó khăn hơn Do đó, việc hiểu rõ chức năng và tầm quan trọng của form tủ giúp chủ đầu tư và chuyên gia tư vấn lựa chọn đúng loại tủ điện hạ thế phù hợp với đặc tính của dự án Ngoài ra, một tiêu chuẩn phân loại tủ điện quan trọng khác là theo cấp độ bảo vệ IP, dùng để chỉ khả năng chống bụi và nước của tủ.
Mức độ bảo vệ của tủ đƣợc thể hiện ở kí hiệu IP, đƣợc nêu trong IEC 60529 Việc Bảo vệ là chống lại những tác động bên ngoài sau đây :
Sự xâm nhập của các vật cứng
Bảo vệ con người chống tiếp xúc với phần có điện , chống bụi , chống thấm
Bảo vệ chống xâm nhập của bụi
Bảo vệ chống thâm nhập cảu chất lỏng

Ghép các khoang tủ điện
- Đặt các khoang tủ vào đúng vị trí cần lắp đặt
- Gỡ bỏ tất cả phần bao bọc khi vận chuyển tủ
- Tháo các tấm che và các phần phụ khác để thuận tiện cho quá trình thao tác trong tủ
- Các khoang tủ có thể đƣợc lắp đặt bắt đầu từ phải qua trái, từ trái qua phải hoặc từ giữa
- Đặt khoang tủ đầu tiên vào vị trí và bắt chặt xuống nền bằng bulong M12 dùng các lỗ có sẵn trên đế tủ
- Khoang tủ thứ 2 ghép với khoang tủ thứ nhất bằng bulong M10 dùng các lỗ đã có sẵn trên khung tủ
- Làm tương tự cho các khoang tủ còn lại
Lưu ý rằng nếu mặt sàn đặt tủ không bằng phẳng, bạn cần phải điều chỉnh các ngăn tủ cân bằng trước khi sử dụng bu lông để cố định chắc chắn Sau đó, tiến hành nối thanh cái và thanh tiếp địa với nhau để đảm bảo hệ thống điện an toàn và hoạt động ổn định.
Nối các thanh cái đồng theo trình tự sau:
+ Để bản đồng nối phía dưới thanh cái đồng rồi đẩy lên vào giữa các khe của thanh cái
+ Gióng thẳng hàng các lỗ để xỏ bulong
+ Bắt bulong, long-đen và ê cu
+ Chiều dài bulong phụ thuộc vào số thanh đồng cần nối và khoảng cách cách điện yêu cầu
+ Siết chặt tất cả các Ê-cu với mô-men yêu cầu dùng cờ-lê lực như trong bảng dưới đây:

When designing an MSB transformer distribution system, the following key factors must be considered: load demand, voltage regulation, power factor correction, and system protection These factors are crucial for ensuring the efficient and reliable operation of the distribution system Load demand refers to the amount of electricity required by the customers connected to the system, and it is essential to accurately estimate this demand to ensure that the system is adequately sized Voltage regulation involves maintaining the voltage within acceptable limits at the customer's premises, and it is important to employ techniques such as capacitor banks and voltage regulators to achieve this Power factor correction aims to improve the power factor of the system, thereby reducing losses and improving efficiency, and it can be achieved through the use of capacitors or synchronous condensers System protection is crucial for ensuring the safety and reliability of the system, and it involves the use of protective devices such as fuses, circuit breakers, and relays to isolate faults and prevent damage to equipment.

QUY TRÌNH VẬN HÀNH TỦ MSB
VẬN HÀNH BỘ ĐIỀU KHIỂN ATS:
Bộ điều khiển ATS có 2 chế độ vận hành (Auto/Man)
Chế độ man( vận hành bằng tay): Ở chế độ vận hành bằng tay theo khóa đóng ngắt trên mặt tủ, người vận hành chuyển khóa lựa chọn Auto-Off-Man về vị trí MAN rồi thao tác nút nhấn ON/OFF trên mặt tủ và quan sát đèn báo trạng thái để thấy đƣợc trạng thái hoạt động của MCCB
Thông thường tủ được thiết kế chỉ cho phép đóng CB khi nguồn điện đã có điện
Chế độ auto( vận hành tự động):
* Khi lưới điện bị một trong các sự cố sau: mất pha, mất trung tính, thấp áp (tùy chỉnh, cài mặc định 170VAC) thì tủ ATS gởi tín hiệu về cho máy phát điện thực hiện việc khởi động Khi máy đã vận hành ổn định và điện máy phát ra đạt giá trị cho phép thì tủ ats tiếp tục trì hoãn thêm một thời gian để làm nóng máy – Warm Up Timer (Thời gian này tùy chỉnh theo yêu cầu từng loại máy, mặc định là 10 giây) Lúc thời gian này kết thúc thì tủ ATS tự động đóng nguồn điện máy cung cấp ra phụ tải
* Lúc lưới điện bình thường trở lại (Đạt tiêu chuẩn yêu cầu về pha và điện áp) thì tủ ATS tiến hành giám sát thêm một thời gian – Restore Timer (Thời gian này tùy chỉnh theo yêu cầu thực tế, mặc định là 10 giây) Khi kết thúc khoảng thời gian này tủ ATS tiến hành cắt phụ tải ra khỏi nguồn điện máy Kế đến thực hiện tiếp thời gian trễ đóng lưới điện vào phụ tải – Transfer Timer (tùy chỉnh, mặc định là 5 giây) Kết thúc thời gian này tủ ats điều khiển đóng lưới điện ra cho phụ tải sử dụng trở lại Khi lưới điện đã cung cấp ra phụ tải thì tủ ATS duy trì cho máy phát điện tiếp tục vận hành không tải thêm một thời gian – Cooling Down Timer (Thời gian này tùy chỉnh theo yêu cầu từng loại máy, mặc định là 15 giây) rồi mới tín hiệu về để dừng máy phát điện nhằm làm tăng tuổi thọ cho máy
