Abstract
The utility model relates to a control device automatically changing over double power supplies. An input end of a main power supply of the control device is connected with a normal power supply via one route of a double-power-supply changeover switch, and the other route of the changeover switch is connected with an emergency power supply. The control device automatically changing over double power supplies can meet the requirement that another power supply can be manually or automatically changed over for continuous equipment running in power supply accidents such as under voltage, phase loss and the like of a power supply, saves time and labor, guarantees production and saves cost.
Description
Technical field
The utility model relates to a kind of dual power supply automatic switching device, relates in particular to the control device that duplicate supply automaticallyes switch.
Background technology
Coal pulverizer is used for the pulverizing of equipment such as power plant, metallurgy, mine, cement machinery, oil station is used for the lubricating of sound bearing of coal pulverizer, the oil station plays critical effect as the subsidiary engine of coal pulverizer, power plant, metallurgy, mine, cement machinery are very high to the requirement of equipment, generally start up and do not allow careless parking, electric main circuit power is the lifeblood of equipment, in case it is serious to production loss to stop.Single supply control user uses very inconvenient, and running into the power supply accident can only all stop.
Summary of the invention
The deficiency that the utility model exists at existing oil station Electrical Control Technology, but the control device that provides a kind of duplicate supply simple in structure, easy to use to automatically switch.
The utility model adopts following technical proposals to realize:
The control device that duplicate supply automaticallyes switch, the input of general supply is connected with normal power source by double power supply automatic switching switch one tunnel, and another road is connected with emergency power supply.
There is one of them power supply to communicate after normal power source and emergency power supply switch and finishes the supply of power supply with general supply.
The utility model dual-power automatic switchover control device manually or automatically can both switch to another power supply and continue equipment operation in the time of can satisfying power supply accident such as power supply under voltage, the phase failure, time saving and energy saving, guarantees to produce, and saves cost.
Description of drawings
Fig. 1 is the utility model structure chart.
