一种电网变压器用辅助开关
摘要：
本发明公开了一种电网变压器用辅助开关，所述电网变压器用辅助开关构成如下：上端盖组件、下端盖组件、绝缘安装板、指示针、接触片及触点组件和轴组件；所述绝缘安装板位于上端盖组件和下端盖组件之间，轴组件贯穿于绝缘安装板内，指示针连接与轴组件的一端，触点组件套在轴组件上，接触片与触点组件相连接。所述电网变压器用辅助开关为机械结构开关，所以该行程开关可靠性较高，结构简单，性能稳定，市场前景广阔。可在-55℃～70℃条件下稳定工作，试验指标满足GB 14048.5相关要求，具有较大的市场和社会价值。
摘要（英）：

The invention discloses an auxiliary switch for a power grid transformer. The switch comprises an upper end cover assembly, a lower end cover assembly, an insulating installation plate, an indicator hand, a contact sheet, a contact assembly, and a shaft assembly. The insulating installation plate is located between the upper end cover assembly and the lower end cover assembly. The shaft assembly is arranged through the insulating installation plate. The indicator hand is connected with one end of the shaft assembly. The contact assembly is installed on the shaft assembly. The contact sheet is connected with the contact assembly. The switch is a mechanical structure switch, and thus the stroke switch is high in reliability, simple in structure, and stable in performance, and has a broad market prospect. The switch can work stably between -55 and 70 DEG C. Test indices of the switch meets related requirements of GB 14048.5. The switch has large market and social value.
