The invention provides a double-power-supply automatic change-over switch. The double-power-supply automatic change-over switch comprises a frequently-used power supply port, a standby power supply port, an output port and a shell mechanism, wherein the frequently-used power supply port, the standby power supply port and the output port are all formed in the shell mechanism, the frequently-used power supply port is connected with the input end of a main power supply through a signal line, the standby power supply port is connected with the input end of a standby power supply through a signal line, and the input end of the main power supply, the input end of the standby power supply and the signal lines are all arranged in the shell mechanism. According to the double-power-supply automatic change-over switch, the power supplies and circuits are arranged inside, only a line port is left outside, a copper bar is pre-arranged on the port and can be directly connected with a frequently-used power supply circuit, a standby power supply circuit and an output power supply circuit, in this way, the structure that that double-power-supply automatic change-over switch is directly connected with the copper bar can be formed, and the requirement for the stability of a double-power-supply adapter power supply circuit is further met.
Description
technical field [0001] The invention relates to the field of electric equipment, in particular to a double power supply automatic transfer switch. Background technique [0002] Dual power automatic transfer switch is widely used in factories, mines or units with first-class load and second-class load. The working mode of the dual-power automatic transfer switch is that when the common power supply is switched on and disconnected, the backup power supply is immediately connected to achieve uninterrupted power supply requirements. In the context of using such a large number of dual-power automatic transfer switches, people's demand for dual-power automatic transfer switches is not only based on practicality and safety, but also on the basis of these standards. The difficulty of the installation method, the convenience of disassembly and replacement, and even the aesthetics of the dual power automatic transfer switch itself are selected. The copper bars of the existing dual-p...
