AI Technical Summary

Problems solved by technology

The electromagnets at both ends directly drive the moving contact to rotate through the connecting rod. Due to the limitation of the connecting rod system, the rotation angle of the moving contact is usually relatively small. To ensure sufficient electrical clearance, a larger overall size is usually required, or a double-break point structure, so that the volume or cost of the product increases

Abstract

The invention discloses a double-power change-over switch device. The device comprises a housing, an electromagnet, a dynamic iron core, a rack, a gear, a dynamic contact, a static contact and a spring; the electromagnet drives the dynamic iron core to move to drive the rack to move leftwards or rightwards, and the rack drives the gear to rotate so as to drive the dynamic contact to rotate round a rotating center; when the contact passes through the medium position, the spring can drive the gear to continuously rotate, so as to enable the dynamic contact to selectively contact the static contact at the left side or the right side; finally the spring enables the dynamic contact to be kept in a position in contact with the static contact at the left side or the right side. The double-power change-over switch device has the beneficial effects that a large electrical gap can be formed between the dynamic contact and the static contact by the electromagnet through a small travel; the device is compact in structure, safe, reliable, and small in cost.

Description

technical field [0001] The present invention relates to a dual power supply conversion switch, which is used to convert the power supply from commercial power supply to emergency power supply or other power supply such as emergency power supply when the commercial power supply connected to the load is cut off, or to automatically switch to commercial power supply when the commercial power supply is restored. Background technique [0002] A power transfer switch is a device that converts multiple power sources and supplies them to loads, and is widely used in homes and facilities that have emergency power sources (backup power sources) such as generators for power outages. Therefore, the conversion between different power sources must have a reliable electrical gap, and at the same time, the product should be as compact as possible. [0003] Existing products mostly share a moving contact in the middle, and choose to contact the moving contacts at both ends respectively. The...
