At present, with the rapid development of big data, intelligent transportation, e-commerce and smart city networks in China, the construction of data centers is in the ascendant.
Data center design specifications require that its power supply and distribution system should be redundant and fault-tolerant. Automatic transfer switch appliance (ATSE) is located at the convergence point of two power systems (single node). Once it fails or needs maintenance, it will bring the risk of power failure to the power supply system of the data center. Bypass ATSE can increase the redundancy of the power supply system and greatly improve the continuity and reliability of the power supply system.
WHKQ18 series bypass transfer switch appliances and complete sets of equipment can meet the needs of important application places such as data centers.
Product Features:
It can provide reliable redundant power conversion function.
Bypass transfer switch appliances are vibration-resistant. The vibration level reaches the test frequency range specified in GB/T 2423.56-2006 from 5Hz to 500Hz, the root mean square value of acceleration is 0.5 g, the test time is 30min, and each axial direction is 10min (X, Y and Z directions).
The controller has reliable electrical stress performance.
The installation methods of ATSE, MTSE and RTSE in production are all drawer-type, and the replacement and maintenance of drawer-type products are convenient and quick.
Drawer-type products have three-position functions of "disconnect, test and connect", which is convenient for debugging and maintenance.
Use category: AC-33A
There are reliable mechanical interlocks. Ensure that the bypass transfer switch appliances can only be closed on the same side, thus ensuring the reliability and safety of the product.
Neutral line overlap switching function:
The N phase adopts the method of first closing and then splitting, which can protect various components at the load end.
N phase adopts overlapping switching mode to prevent voltage floating.
