The coil of the contactor is connected with a main power supply, when the main power supply is electrified, the armature of the contactor is attracted, and the moving contact is driven to be communicated with the contact of the main power supply, so that the main power supply supplies power. When the main power supply is powered off, the coil of the contactor is powered off, and the armature of the contactor is disconnected under the action of the spring force to drive the movable contact to be connected with the contact of the standby power supply, so that the standby power supply supplies power. The utility model can automatically switch, but can not be controlled manually, and has hidden danger in unexpected situations.
The utility model with the patent application number of 2016102002528 provides a dual-power switching control loop of a CEMS (continuous emission monitoring system), wherein a CEMS power supply main line is connected with a security section power supply through a normally open auxiliary contact KM1-1 and a switch K1 of an alternating current contactor KM1 in sequence, and a normally closed auxiliary contact KM2-2 is connected with an alternating current contactor KM1 in series and then connected with L1 and N1 of the security section power supply in series between the normally open auxiliary contact KM1-1 and the switch K1; the utility model ensures the CEMS double power supply switching by adopting the interlocking power supply of the UPS power supply and the security section power supply, and solves the problem that important equipment is restarted due to power loss when the single power supply is lost; the utility model can not solve the problem of UPS undervoltage caused by long-term power failure of the external power supply.
