接地保护装置
摘要：
本发明公开了一种接地保护装置，包括箱体、控制器和与低压电路连接的三相闸刀，控制器分别连接有电流检测装置、闸刀锁止装置和人体检测装置：闸刀锁止装置与三相闸刀连接以对其进行锁止，人体检测装置当人体靠近把手时发送感应信号至控制器；当电流检测装置检测到电流信号且人体检测装置检测到有人体靠近把手时，控制器发送锁止信号至闸刀锁止装置以对三相闸刀进行锁止。应用本发明公开的接地保护装置，当低压电路存在静电或残余电压且通过人体检测装置检测到有人靠近把手时，控制器发送锁止信号至闸刀锁止装置对三相闸刀进行锁止，避免误重合闸刀操作，有效防止线路短路事故的发生，且方便快捷，省时省力。
摘要（英）：

The invention discloses a ground protection device. The ground protection device comprises a box, a controller and a three-phase disconnector which is connected with a low-voltage circuit, wherein the controller is connected with a current detection device, a disconnector locking device and a human body detection device; the disconnector locking device is connected with the three-phase disconnector to lock the three-phase disconnector; the human body detection device sends a sensing signal to the controller when a human body approaches a handle; when the current detection device detects a current signal and the human body detection device determines that the human body approaches the handle, the controller sends a locking signal to the disconnector locking device so as to lock the three-phase disconnector. With application of the ground protection device, when static electricity or residual voltage exists in the low-voltage circuit and the human body detection device determines that the human body approaches the handle, the controller sends the locking signal to the disconnector locking device so as to lock the three-phase disconnector, mistaken re-switching-on of the disconnector is avoided, a short-circuit accident of the circuit is prevented effectively, and the device is convenient, fast, time-saving and labor-saving.
