Locking structure for medium-voltage switchgear
The invention discloses a locking structure for medium-voltage switch equipment, which is characterized by comprising a locking electromagnet mounting bracket arranged at a cable chamber door of a cabinet body, a locking electromagnet mounting limiting hole is formed in the locking electromagnet mounting bracket, a locking electromagnet is aligned with the locking electromagnet mounting limiting hole for axial mounting, and the locking electromagnet mounting limiting hole is provided with a locking electromagnet mounting hole; the other end of the latching electromagnet is movably inserted into a latching electromagnet bolt, and the latching electromagnet bolt covers the side wall; under the power-on condition, the latching electromagnet is controlled by an external circuit to move towards the latching electromagnet bolt and be inserted into the latching electromagnet bolt, so that the effect of closing the cabinet cable chamber door is achieved. According to the invention, the number and depth of the holes in the cabinet cable chamber door (rear door) can be greatly reduced, and the situation that the strength of the cabinet cable chamber door (rear door) is reduced and the arcing performance of the switch cabinet is influenced is avoided.
本发明公开了一种用于中压开关设备的闭锁结构，其特征在于，包括：设置在柜体电缆室门处的闭锁电磁铁安装支架，所述闭锁电磁铁安装支架上开设有闭锁电磁铁安装限位孔，将闭锁电磁铁对准所述闭锁电磁铁安装限位孔进行轴向安装，所述闭锁电磁铁的另一端活动插入闭锁电磁铁插销当中，所述闭锁电磁铁插销覆盖在侧壁上；在通电情况下，通过外部电路来控制闭锁电磁铁朝向闭锁电磁铁插销的方向移动并插入所述闭锁电磁铁插销当中，以实现关闭所述柜体电缆室门的作用。本发明可以大幅降低在柜体电缆室门(后门)上的开孔数量和开孔深度，避免导致柜体电缆室门(后门)强度降低，影响开关柜的燃弧性能。
