Abstract

The invention relates to the technical field of dual-power switching devices, in particular to a dual-power switching device with an intelligent anti-interference structure, which comprises a box body, an anti-interference box body is mounted in the middle of the upper surface of an inner cavity of the box body, and vacuum arc extinguish chambers are mounted on the left side and the right side of the upper surface of the inner cavity of the box body; fixed feeler levers are installed on the left side and the right side of the upper surface of an inner cavity of the box body and penetrate through the vacuum arc-extinguishing chamber, fixed contacts are installed at the lower ends of the fixed feeler levers, a movable feeler lever is movably installed in the middle of the lower surface of the vacuum arc-extinguishing chamber in a penetrating mode, the upper end of the movable feeler lever is located in an inner cavity of the vacuum arc-extinguishing chamber, and movable contacts are installed at the upper end of the movable feeler lever. The lower end of the movable feeler lever is provided with an insulating rod. According to the invention, through mutual cooperation of structures, switching work of dual power supplies can be realized through a simple structure, the switching speed is relatively high, the danger of electric shock during maintenance can be avoided, the safety of the device is improved, and the cleanliness of lines in the device is ensured.

Description

technical field [0001] The invention relates to the technical field of a dual power switching device, in particular to a dual power switching device with an intelligent anti-interference structure. Background technique [0002] With the development of the national economy, more and more attention has been paid to the safety of electricity use and continuous power supply in today's society. Many important places such as hospitals, airports, banks, and data centers cannot be powered off for a moment. Power outages bring more than just Economic losses, and many personal injuries caused by power outages, so now many places need to use dual power switches to ensure continuous power supply capability. [0003] The power control structure of many existing dual power switching devices is complicated and the cost is high, and there is a potential safety hazard of electric shock during maintenance, and many existing dual power switching devices have complex internal circuits, resultin...
