Sau khi Thủ tướng Chính phủ ban hành Quyết định 11/2017/QĐ-TTg về cơ chế khuyến khích phát triển các dự án điện mặt trời tại Việt Nam, nhiều hộ gia đình nước ta đã đã trở thành nhà đầu tư vào điện mặt trời. Theo đó, các công ty đẩy mạnh sản xuất nhưng việc đảm bảo chất lượng của các tấm pin là việc làm không thể lơ là. Vecomtech là nhà phân phối độc quyền của hãng ACES, một trong những hãng hàng đầu tại Mỹ về các thiết bị kiểm tra chất lượng pin mặt trời. Chúng tối cung cấp các thiết bị như: - Kiểm tra dòng điện, nhiệt độ, độ ẩm - Kiểm tra kết cấu bề mặt - Kiểm tra rò rỉ - Kiểm tra độ bền: kéo, xoắn,... - Kiểm tra mô phỏng: tủ thử UV, mô phỏng mưa đá... - và hệ thống giám sát Nguyen Dinh Toan Sales Engineer Vecomtech Co., LtdRoom 406, Kim Anh building, Lane 78, Duy Tan street, Cau Giay district, Hanoi, VietnamHotline: 024.3754.9061 # Fax: 024.3754.9063 # Mobile: 098.766.7103Email: dinhtoan.tkh@gmail.comWebsite: https://vecomtech.com Facebook: https://www.facebook.com/vecomtechcoltd/
BR-PV-VIT Visual inspection series instruments Perform standards: IEC 61215-2:2016, IEC 61730-2:2016, VDE 0126-5:2008… Visual inspection table: Table Size: ≥2.2m×1.2m Illumination: >1000Lux @ area (2m×1m) Table material: Green mat Frame material: Aluminum alloy profile With drawers, for storing tools Attachment: - Illumination meter: Automatic range switching, Measurement range: 0~20~200~2000~20000Lux - Magnifying glass, Straightedge - Digital camera Purpose To detect any visual defects in the module. Procedure Carefully inspect each module under an illumination of not less than 1000 lux for the following conditions: – cracked, bent, misaligned or torn external surfaces; – broken cells; – cracked cells; – faulty interconnections or joints; – cells touching one another or the frame; – failure of adhesive bonds; – bubbles or delaminations forming a continuous path between a cell and the edge of the module; – tacky surfaces of plastic materials; – faulty terminations, exposed live electrical parts; – any other conditions which may affect performance. Make note of and/or photograph the nature and position of any cracks, bubbles or delaminations, etc. which may worsen and adversely affect the module performance in subsequent tests.
Thermal Cycling, Humidity-Freeze, Damp-Heat Tester Perform standards: IEC 61215-2:2016, IEC 62108:2007, UL 1703-2015… Thermal Cycling Test Perform standards: IEC 61215-2:2016 “TC200 thermal cycling test, TC50 thermal cycling test”, and UL 1703-2015 “temperature cycling test”. 1. IEC 61215-2:2016 test condition: The temperature of modules between -40°C±2°C and +85°C±2°C cycling, the rate of change of temperature between the low and high extremes shall not exceed 100°C/h and the module temperature shall remain stable at each extreme for a period of at least 10 min. The cycle time shall not exceed 6h. 2. UL 1703-2015 test condition: The temperature of modules between -40°C±2°C and +90°C±2°C cycling, the instantaneous rate of temperature change of the test chamber with respect to time is not to be greater than 120°C/h. Humidity-Freeze Test Perform standards: IEC 61215-2:2016 “humidity-freeze”, UL 1703-2015 “humidity test” The temperature of modules between -40°C±2°C and +85°C±2°C cycling. Relative humidity 85%RH±5% at 85°C in IEC 61215 and 61646, but UL 1703 Control in 85%RH±2.5% at 85°C, allowable deviation range different. Damp-Heat Test Perform standards: IEC 61215-2:2016 “damp-heat test” Test temperature 85°C±2°C, Relative humidity 85%±5%, Test duration 1000h Electrical continuity, Insulation continuity, Grounding continuity test system: Perform standards: IEC 61215-2:2016 “electrical continuity for TC200 thermal cycling test and humidity-freeze test” conditions, and UL 1703-2015 “Insulation continuity and grounding continuity” condition. DC power current / voltage output: 25A/60V or 10A/150V IEC 61215-2:2016 During the thermal cycling test set the continuous current flow during the heat up cycle to module Imp current at temperature from -40°C to 80°C. During cool down, the -40°C dwell phase and temperatures above 80°C the continuous current shall be reduced to no more than 1.0% of the measured STC peak power current to measure continuity. During the humidity freeze test set the continuous current flow to no more than 0.5% of the measured STC peak power current.
