Buckle releaser for constant open ground failure breaker

常开型接地故障断路器用脱扣器

Abstract

The utility model discloses a normal open type ground fault breaker release, which comprises a bracket, a static contact, a moving contact connected with the bracket, a locking mechanism, a reset button and a testing button which are fixed on the bracket, an armature and a release coil, wherein, the release coil comprises a first coil controlled by a programmable integrated module and driving the armature to press the locking mechanism and a second coil controlled by a programmable integrated module and driving the armature to push the locking mechanism. The utility model has the advantages that no electric current flows over the coil because the combination of a switch tube and a release is realized to the normal open type release , and the utility model does not consume power; when a counter connection fault exists, the coil of the release has no working power supply, thereby the counter connection protection is realized.
本实用新型公开了一种常开型接地故障断路器用脱扣器,包括支架、静触头、与支架连接的动触头、抱锁机构、固定在支架上的复位按钮和测试按钮、衔铁以及脱扣器线圈,所述脱扣器线圈包括受可编程集成模块控制的驱动衔铁顶压抱锁机构的第一线圈和受可编程集成模块控制的驱动衔铁拉动抱锁机构的第二线圈。本实用新型具有如下优点:因为采用开关管与脱扣器配合实现常开型脱扣器,线圈中没有电流流过,不消耗功率;当存在反接线故障时,脱扣器的线圈没有工作电源,实现了反接线保护。
