Background technology
Switch cubicle is the electric power electrical control cabinet again, is a kind of switchgear assembly and control appliance, and is main with control, the supervision done power circuit, main power consumption equipment, and overload, short circuit, the electric leakage of circuit shielded; The switch cubicle actuation means is a kind of device of controlling the executive component that is connected and obtaining executive component information.
Existing switch cubicle actuation means leans on external power source, when disconnecting external power source, and can not the interior humiture parameter of sense switch cabinet.When switching on once more before the switch cubicle energising is used or after the maintenance, when directly sending high-tension electricity to switch cubicle if the interior humidity of cabinet is excessive, can cause the electrical insulation properties of equipment in the cabinet to descend, cause equipment room phenomenons such as creepage, electric leakage to occur, will cause electric equipment and circuit to have a strong impact on.
The utility model content:
The utility model is at problems of the prior art, provide a kind of can be under the situation of no external power source input the switch cubicle actuation means of humiture in the normal measuring switch cabinet.For this reason, the utility model adopts following technical scheme:
A kind of switch cubicle actuation means, comprise main power source, charged testing circuit, switching power circuit, electric source monitoring circuit, single-chip microcomputer and circuit board power supply, it is characterized in that: also comprise a stand-by power supply, rechargeable battery and active and standby power supply automatic switchover circuit, wherein, one end of described main power source enters active and standby power supply automatic switchover circuit by charged testing circuit, and the other end directly enters the main power source end of the alternative diverter switch of active and standby power supply automatic switchover circuit; One end of described stand-by power supply enters active and standby power supply automatic switchover circuit through first switching power circuit, and the other end directly enters the stand-by power supply end of the alternative diverter switch of active and standby power supply automatic switchover circuit; One end of described rechargeable battery is connected to first switching power circuit, and the other end is connected in electric source monitoring circuit; The output of described active and standby power supply automatic switchover circuit is connected to the second switch power circuit.
The utility model is owing to increased by a stand-by power supply circuit, when there is the power supply power supply outside, power supply by the input of stand-by power supply input charges the battery, when the outside does not have power supply to supply with, switch to powered battery by power supply switch circuit, like this, just can when not having the external power source input, open by switch cubicle this device, thereby can before the switch cubicle energized, open this device earlier, the humiture in the cabinet is detected.When if humidity surpasses safety value, can handle in the cabinet after the humidity energized more earlier well.Can reduce the risk of first energising or the energising of maintenance back like this.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing preferred implementation of the present utility model is described in further detail.Will be to part same as the prior art in the utility model with reference to prior art.
As shown in Figure 1, the utility model comprises a main power source 1, one end of main power source 1 enters active and standby power supply automatic switchover circuit 4 by charged testing circuit 3, and the other end of main power source 1 directly enters the main power source end of the alternative diverter switch of active and standby power supply automatic switchover circuit 4; A stand-by power supply 2, one end of this stand-by power supply 2 through 9 step-downs of first switching power circuit, rectification, filtering laggardly become owner of, stand-by power source automatic switch-over circuit 4, other end end directly enters the stand-by power supply end of the alternative diverter switch of active and standby power supply automatic switchover circuit 4; The output of active and standby power supply automatic switchover circuit 4 is connected to second switch power circuit 5; An electric source monitoring circuit 6 is used to judge on second switch power circuit 5 loops whether voltage is arranged; A rechargeable battery 10, an end of this battery 10 is connected to first switching power circuit 9, and the other end is connected in electric source monitoring circuit 6.
Operation principle of the present utility model is as follows: from outside No. one stand-by power supply 2 (maintenance power supply) of introducing of switch cubicle actuation means (hereinafter to be referred as device), for primary, spare power supply automatic switchover circuit 4 provides one road direct current 12V working power, this 12V power supply also provides charging current for rechargeable battery 10 to these stand-by power supply 2 one side simultaneously after 9 step-downs of first switching power circuit, rectification, filtering; Another road of stand-by power supply 2 directly enters the stand-by power supply end of the alternative diverter switch of primary, spare power supply automatic switchover circuit 4.
