Description

Technical Field

[0001] The utility model relates to the technical field of static transfer switches, and particularly relates to a 3U static switch STS power module. Background Technique

[0002] The static transfer switch is mainly used for the switching of dual power supplies, and is an automatic switching system for selecting one of the two power supplies. Under normal working conditions, when the main power supply is within the normal voltage range, the load is always connected to the main power supply. When the main power supply fails, the load automatically switches to the standby power supply, and when the main power supply returns to normal, the load automatically switches back to the main power supply.

[0003] Each control element of the static transfer switch is integrated on a circuit board and controlled by a processor. When the static transfer switch works, a patch type heat sink is used to dissipate heat from key areas such as the processor. However, the patch type heat dissipation structure cannot efficiently perform installation and positioning processing, and the heat conducting sheet provided on the patch type heat dissipation structure is likely to damage the circuit board. Therefore, we propose a 3U static switch STS power module. Content of the Utility Model
