Tìm hiểu chi tiết về cấp cách điện và tiêu chuẩn bảo vệ

Bài viết dưới đây, công ty Minh Quân sẽ giúp các bạn hiểu rõ hơn về cấp cách điện và tiêu chuẩn bảo vệ được in trên nhãn mỗi loại bơm xem nó đáp ứng được độ an toàn đến đâu.

1. Cấp cách điện

Định nghĩa

Cấp cách điện có tên tiếng anh là insulation class hay còn được gọi là hệ thống cách điện. Theo tiêu chuẩn IEC 60085 tùy thuộc vào Nhiệt và độ biến nhiệt mà dây điện được sử dụng trong máy phát điện, động cơ điện, đầu phát điện, máy biến áp và các chi tiết điện được chia thành nhiều lớp khác nhau.

Bảng chi tiết 7 lớp cách điện

bảng chi tiết 7 lớp cách điện
bảng chi tiết 7 lớp cách điện

Thường lớp cách điện được áp dụng trên mỗi máy bơm chìm thường sử dụng lớp cách điện lớp B có thể cách điện tốt tại nhiệt độ lên đến 130 ºC. Chính vì thế máy bơm có thể hoạt động tốt nếu máy chạy không quá nóng đến dưới 130 ºC. Nếu nó nóng quá 130 ºC có thể dẫn đến chập cháy.

2. Tiêu chuẩn bảo vệ

Định nghĩa

IP là tiêu chuẩn được định nghĩa bởi IEC, nó quy định mức độ bảo vệ của thiết bị điện từ bụi và nước trong đó:

  • I là tiêu chuẩn chống bụi được phân làm 6 cấp độ từ ngăn được những hạt bụi lớn hơn 50mm tại mức độ 1 đến ngăn hoàn toàn bụi tại cấp độ 6.
  • P là tiêu chuẩn chống nước được phân làm 9 cấp độ từ không có sự bảo vệ đến có thể ngâm trong nước trong độ sâu lớn và thời gian dài mà thiết bị vẫn hoạt động được.

Chi tiết ý nghĩa các thông số chống bụi bẩn ( I ) và chống nước ( P )

Ý nghĩa thông số thứ nhất I chống bụi

  • 1: Cho biết để ngăn chặn sự xâm nhập của các vật thể rắn lớn hơn 50mm.  Bảo vệ từ đối tượng (chẳng hạn như bàn tay) chạm vào các bộ phận đèn do ngẫu nhiên. Ngăn chặn các vật có kích thước (có đường kính) lớn hơn 50mm.
  • 2: Cho biết có thể ngăn chặn cuộc xâm nhập của các đối tượng có kích thước trung bình lớn hơn 12mm. Ngăn chặn sự xâm nhập của ngón tay và các đối tượng khác với kích thước trung bình (đường kính lớn hơn 12mm, chiều dài lớn hơn 80mm).
  • 3: Cho biết để ngăn chặn cuộc xâm nhập của các đối tượng rắn lớn hơn 2.5mm. Ngăn chặn các đối tượng (như công cụ, các loại dây hoặc tương tự) có đường kính hoặc độ dày lớn hơn 2,5 mm để chạm vào các bộ phận bên trong của đèn.
  • 4: Cho biết để ngăn chặn sự xâm nhập của các vật rắn lớn hơn 1.0mm. Ngăn chặn các đối tượng (công cụ, dây hoặc tương tự) với đường kính hoặc độ dày lớn hơn 1.0mm chạm vào bên trong của đèn.
  • 5: Chỉ ra bảo vệ bụi. Ngăn chặn sự xâm nhập hoàn toàn của vật rắn, nó không thể ngăn chặn sự xâm nhập bụi hoàn toàn, nhưng bụi xâm nhập không ảnh hưởng đến hoạt động bình thường của thiết bị.
  • 6: Chỉ ra bảo vệ bụi hoàn toàn. Ngăn chặn sự xâm nhập của các đối tượng và bụi hoàn toàn.

Ý nghĩa thông số thứ hai P chống nước

  • 0 Cho biết không có bảo vệ.
  • 1 Chỉ ngăn chặn sự xâm nhập của nước nhỏ giọt. Nước giọt thẳng đứng (như mưa, không kèm theo gió) không ảnh hưởng đến hoạt động của thiết bị.
  • 2 Chỉ ngăn chặn được sự xâm nhập của nước ở góc nghiêng 15 độ. Hoặc khi thiết bị được nghiêng 15 độ, nước nhỏ giọt thẳng đứng sẽ không gây ra tác hại nào.
  • 3 Cho biết có thể ngăn chặn sự xâm nhập của tia nước nhỏ, nhẹ. Thiết bị có thể chịu được các tia nước, vòi nước sinh hoạt ở góc nhỏ hơn 60 độ (Cụ thể như mưa kèm theo gió mạnh)
  • 4 Cho biết để ngăn chặn sự xâm nhập của nước từ vòi phun ở tất cả các hướng. 
  • 5 Cho biết để ngăn chặn sự xâm nhập của nước vòi phun áp lực lớn ở tất cả các hướng.
  • 6 Cho biết có thể chống sự xâm nhập của những con sóng lớn. Thiết bị có thể lắp trên boong tàu, và có thể chịu được những con sóng lớn.
  • 7 Cho biết có thể ngâm thiết bị trong nước trong 1 thời gian ngắn ở áp lực nước nhỏ.
  • 8 Cho biết thiết bị có thể hoạt động bình thường khi ngâm lâu trong nước ở 1 áp suất nước nhất định nào đó, và đảm bảo rằng không có hại do nước gây ra.

Vậy một thiết bị máy bơm chìm có cấp độ bảo vệ IP68 nghĩa là nó có thể chống được bụi bẩn cũng như nước là tuyệt đối và được an toàn hoạt động khi được thả sâu trong nước.
