Detailed Description
The utility model is further described below in connection with the examples, which are not to be construed as limiting the utility model in any way, but rather as falling within the scope of the claims.
Referring to fig. 1, the intelligent automatic power-off charging control device comprises an air switch, an isolator I, a surge protector, a time delay switch, a timer and a contactor. The air switch is connected with an external power supply through a double-power automatic change-over switch, so that the double power supply is arranged for the charging control device, and the phenomenon that the charging control device is powered off is prevented. The air switch is connected with the input end of the surge protector through the first isolator. The first isolator and the surge protector are used for processing peak voltage and surge current, so that the charging device and an enterprise internal power grid can be isolated, the charging device is prevented from being influenced by the peak voltage and the surge current existing in the enterprise internal power grid, and stable operation of the charging device is ensured.
The output end of the surge protector is respectively connected with the input end of the delay switch and the input end of the contactor, and the output end of the delay switch and the output end of the contactor are both connected to the input end of the timer. The output end of the contactor is connected with the input end of the timer through a safety device and a second isolator which are connected in series. The coil of the timer and the contactor can be protected by the arrangement of the protector. And the arrangement of the second isolator can isolate the timer from the load connected with the contactor, so that the problem of crosstalk between the timer and the load is prevented. In addition, the second isolator can prevent the phenomenon that the electric energy input from the delay switch to the input end of the timer is transmitted to the load. The output end of the timer is connected with the control end of the contactor, and the output end of the contactor is used as a load connecting end and is connected with the charging device.
In the embodiment, the effects of timing setting and timing charging are achieved through the double delay action of the delay switch and the timer, and the purposes of saving electric energy and preventing the charging device from being in a working state all the time are achieved. The delay switch adopts a touch delay switch, so that the operation is convenient.
The working principle of the utility model is as follows: the air switch is turned on, and external electric energy is sequentially transmitted to the delay switch and the input end of the contactor through the dual-power supply change-over switch and the air switch. When the delay switch is triggered, the delay switch is turned on, and the electric energy is transmitted to the timer through the protector and the isolator, so that the timer is electrified to work. At this time, the field personnel only needs to set the timing time of the timer in the delay time of the delay switch, and trigger the timing to start, the timer outputs an electric signal to the control end (namely the coil of the contactor) of the contactor, so that the internal switch of the contactor is in a conducting state, and the contactor transmits electric energy to the load.
When the delay time of the delay switch is over, the electric energy required by the timer is transmitted through the contactor, so that the timer can work continuously. After the timing time of the timer is finished, the timer does not output an electric signal any more, so that an internal switch of the contactor is turned off, and meanwhile, the load and the timer are powered off, and the effects of power-off protection and energy conservation are achieved.
In the time delay time of the time delay switch, if the field personnel does not start the timing operation on the timer, after the time delay time is finished, the timer and the load do not have electric energy input, namely the battery of the electric equipment cannot be charged at the moment. Such a setting is advantageous in that when a field person forgets to set the timer, the timer is always in an energized state, which is disadvantageous in terms of power saving.
While only the preferred embodiments of the present utility model have been described above, it should be noted that modifications and improvements can be made by those skilled in the art without departing from the structure of the present utility model, and these do not affect the effect of the implementation of the present utility model and the utility of the patent.
