Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Provided by Fig. 1, the utility model comprises casing 1, watch-dog 6, rectifier 12 and reducing transformer 13, casing 1 top and the bottom are useful on the gland 8 that is fixed on the wall, there is glass door 2 casing 1 front, louvre 9 is all arranged at casing 1 top and bottom, entrance hole 10 and wire hole 11 are arranged at casing 1 bottom, be disposed with from top to bottom power supply room 3 in the casing 1, cabling chamber 4, control room 5, watch-dog 6 is housed in the power supply room 3, rectifier 12, transformer 13, insulation flashing relay 14 and batteries 15 for subsequent use, control switch 7 is housed, the watch-dog 6 of control switch 7 in wire passes through cabling chamber 4 and power supply room 3 in the control room 5, rectifier 12, reducing transformer 13, the insulation flashing relay 14 of ground connection links to each other.
In order to guarantee result of use, described gland 8 has 2-4 that cooperates up and down at least.
Described casing 1 is square.
Main feature of the present utility model is as follows:
1) intelligent AC switching, power failure memory function.
The input of two-way AC power, wherein one the tunnel is working power, and another road is stand-by power supply, and when having a power failure appearred in working power, system automatically switched to stand-by power supply, when working power is normal, switches to working power.Interrupt when exchanging appears in running in equipment, then exchange when recovering, state before equipment automatically returns to and cuts off the power supply, and selection is all filled or the floating charge mode automatically.
2) intelligent charge, automatically adjusting.
When battery is in long-term floating charge and during capacity loss, system enters the constant current charge state automatically, charges to even charging voltage, change the constant voltage charge state over to, when charging current is lower than set point, change floating charge state after the time-delay over to, but the operations staff also manual operation battery is all filled (filling by force).Charging device is to charge in batteries the time, the output voltage of charging module can be higher than the control appliance rated value, continuous-current plant is transmitted electricity to control appliance by the automatic Regulation module, the voltage of the automatic control circuit automatic decision control bus of automatic Regulation inside modules, by adhesive or the release of right quantity performer, with the voltage of guaranteeing control bus within normal range (NR).
3) casing adopts standard design, modularized design.
The continuous-current plant casing adopts the assembling of C type structural shape, has highly versatile, precision high, fully takes into account the operating heat dissipation problem of casing when design.All there is the heat radiation hole slot of varying number at two ends about casing, and when the in-box electric appliance element heating, heat rises, discharge by the upper end hole slot, and cold air is constantly replenished into cabinet by the lower end hole slot, makes the casing of sealing form a natural ventilation channel from bottom to top, reaches the heat radiation purpose.Transparent glass door or organic glass door are adopted in the casing Qianmen, convenient interior each the element running status of cabinet and the instrument parameter of observing.Charging module, monitoring unit, voltage reduction module are installed in the bracket, compact conformation, the equal hot-pluggable of module and monitoring unit, convenient maintenance.Continuous-current plant provides the RS485 serial line interface, is convenient to remote monitoring, realizes " four is distant " function.
Operating position of the present utility model is, adopts the input of two-way alternating current 220V, and the alternating current 220V input power can draw the cabinet from 10KV PT.Can upload or export corresponding alarm signal by communication serial ports and dry contact, be convenient to the networking automation, install elegant in appearancely, assembling flexibly.The utility model aims at the low capacity system; for the systems such as switchette station, small user transformer station, intelligent switching station, Intelligent Combined Substation provide safe and reliable electric power protection power supply and operating power; what also can be used for Small Substation and power distribution room answers the urgent thing power supply, is used in especially unattended operation needs.
The utility model volume is little, saves the space, and easy for installation, cost is low, and result of use is good, is the innovation on the wall-hanging direct current power supply box, has good economic and social benefit.
