Abstract
The invention provides a damping relay comprising a damper and a switch; the damper comprises an armature and the armature triggers the switch. The damping relay has following advantages: the control characteristic depends only on magnitude of current in controlled load or the circuit; the damping relay has random acting characteristics (instantaneous, short, middle, and long time delay); usage environment temperature range is wide (-40 to 85 DEG C) and the acting characteristics are basically not influenced by temperature change, and the damping relay can be applied in circuits in situation of large temperature difference, extreme cold weather, highland, or mobile devices. The damping relay has reliable consistency and stability so that mass production is easy to perform. The control accuracy is high (setting value can be randomly selected between 105% and 145%). The damping relay can be applied in electric appliances with high controlling and protecting requirement; the protection action and restoration are quick so that devices are protected from being burnt down due to overload and quick restoration can be realized (millisecond to second). The damping relay can be also designed to be impact-resistant, shock-resistant, and damp-resistant. The damping relay can be applied in fields of alternate current, direct current and 400Hz military industry.
