一种防尘分合闸用继电器
摘要：
一种防尘分合闸用继电器，属于电气元件，其结构包括成组安装在基板上的继电器本体，每组继电器本体的外侧罩有一个透明的防尘罩，所述的防尘罩一端铰接在基板上，另一端通过螺纹连接件连接在基板上。本实用新型设有防尘罩，当汇控柜的汇控门长时间打开时，能够防止继电器本体进入灰尘，避免因灰尘导致继电器本体触点不良，从而避免由此导致的事故。
摘要（英）：

The utility model discloses a relay applied to dust-proof closing and opening. The relay applied to dust-proof closing and opening belongs to electrical components. The structure of the relay applied to dust-proof closing and opening comprises relay bodies which are arranged on a substrate in groups. The outside of each group of relay bodies is covered with a transparent dust-proof cover. One end of the dust-proof cover is hinged on the substrate, and the other end is connected with the substrate through a screw connecting part. According to the utility model, the dust-proof cover is arranged; when a control door of a control cabinet is opened for a long time, dust is prevented from entering the relay bodies; bad contacts of the relay bodies, which are caused by dust, are prevented; and accidents caused by bad contacts are prevented.
