Description

Drawer interlocking device

Technical field

The present invention relates to the field of low voltage electrical appliances, and more particularly to a transfer switch appliance and its interlocking mechanism.

Background technique

In many important power supply situations, two power supplies are required, such as airports, terminals, hospitals, etc. In order to ensure safe and reliable operation of the load, it is necessary to install an ACES to complete the conversion between power supplies to meet the continuity of the power supply system. . ATSE has a common power side and a backup power side. The operating mechanism (also called the drive mechanism) is an important part of the ATSE. It is a mechanical transmission structure that completes the switching between the common side and the standby side.

In the existing products, although the ATSE can realize the conversion between the two power sources to meet the stability of the power supply, when the ATSE itself fails, it also has to perform a short power-off maintenance, thereby reducing the continuity of the power supply.
