Description

Technical Field

[0001] The utility model relates to the technical field of current limiting reactors, in particular to a zero-loss deep current limiting device. Background Art

[0002] When a short circuit occurs in the system, the zero-loss deep current limiting device can interrupt the short-circuit current within 7-15 milliseconds to achieve deep current limiting. The deep current limiting reactor can open the gate within 5 milliseconds and close the gate within 10 milliseconds, further demonstrating its excellent action speed.

[0003] In the prior art, the lower part of one side of the zero-loss depth current limiter provided in the control box needs to be opened for maintenance. However, there are the following limitations:

[0004] 1. A heat sink is opened on one side of the control box in the zero-loss depth current limiter. When in operation, the inside of the control box needs to be cooled by a cooling fan. However, the cooling fan needs to work continuously, regardless of whether the temperature inside the control box reaches the required threshold for heat dissipation, resulting in energy waste;

[0007] To this end, we propose a zero-loss deep current limiting device. Utility Model Content
