Embodiment Construction
[0047] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.
[0048]In order to start the current limiter in time after a short-circuit fault occurs, it is necessary to ensure that the short-circuit detection platform quickly detects the short-circuit fault. The present invention designs and develops a novel short-circuit detection platform according to the working characteristics of the flux-constrained current-limiting switch. The main detection sche...
