RGV is the transport vehicle with ground guide rail contact.RGV system is comprised of some dollies, Single PLC control unit, central PLC control system, rail system and power supply system of sliding contact line.The circular orbit side of RGV is along the loop wire ditch of turning up the soil, and power supply system of sliding contact line is arranged on the below of rail system, by current-collector, is connected with walking dolly.Integrally-builtly simply be also embodied in the simplification of controlling practical function: RGV moves on ground rail, by current-collector, contact with trolley in the trench of dolly bottom and main control cabinet carries out signal transmission.By the segmentation of trolley, judge in each section of trolley whether have dolly, determine the residing position of dolly.At process section, the speed operation of dolly to synchronize with main line.Main control cabinet is equivalent to dispatching desk, and the residing position of each dolly can allow its identify, and then according to the program of design, it is assigned to work order.
Traditional RGV, generally adopts guide rail sliding contacting mode that Alternating Current Power Supply is provided, and only has a set of electric power system.It is to exchange by inversion that existing AC/DC switching device shifter is direct current, and final out-put supply is Alternating Current Power Supply; Existing ac/dc switching device shifter is and exchanges is direct current by rectification, and final out-put supply is DC power supply.These two kinds of modes finally all only provide a set of electric power system, do not possess redundant power supply ability, when electric power system breaks down, and the whole system state that paralyses.
Utility model content
The purpose of this utility model is to provide a kind of mode of take guide rail sliding contacting mode and contactless DC power-supply system redundant power supply and provides the power switching device of power as RGV, two cover electric power system undisturbeds switch, guarantee the operation of RGV dolly free of discontinuities, any road electric power system fault does not affect system running gear.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A power switching device, comprises Liang Ge remote operation mechanism, two main distribution switches, anxious under-voltage button, two indicator lights of stopping, wherein ，Liang Ge remote operation mechanism, main distribution switch, suddenly stop under-voltage, indicator light and be electrically connected to.
Further, one described, remote operation mechanism is four phase five-wire system 560VDC, 24VDC line loop operation mechanism, and another is three-phase five-wire mode 380VAC line loop operation mechanism.
Further, one described of indicator light is used to refer to four phase five-wire system 560VDC of work at present, the operating state of 24VDC line loop operation mechanism, and another is used to refer to the operating state of three-phase five-wire mode 380VAC line loop operation mechanism.
Further, described remote operation mechanism realizes the switching of supply line by three switch knobs of three gears are set.
The beneficial effect of technique scheme of the present utility model is as follows:
Power switching device of the present utility model adopts direct current, exchanges the switching of two-way redundancy, guarantees electric power system failure-free operation; Adopt guide rail sliding contacting mode and the configuration of non-contact power supply mode redundant power supply, guarantee by this switching device shifter, can switch supply power mode by undisturbed in the situation that each oneway circuit electric power system breaks down, guarantee system stability, operation continuously.
Accompanying drawing explanation
Fig. 1 is guidance panel schematic diagram of the present utility model;
Fig. 2 is 380VAC of the present utility model and 560VDC circuit switching circuit theory diagrams;
Fig. 3 is 24VDC power supply switch circuit schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described.
As shown in Figure 2, the utility model adopts direct current and exchanges the switching mode that supplies power with double circuit, power supply master control cabinet input power is four phase five-wire system 560VDC, 24VDC circuit and the duplex feeding of three-phase five-wire mode 380VAC circuit, by power switching Array selection wherein Yi Lu supply line power, selected power supply remote operation mechanism starts, main distribution switch closes a floodgate, the work at present supply line of indicator light indication is simultaneously normal, when Dang Gai road electric power system breaks down, indicator light extinguishes, alert is switched to another road supply line, not impact system continues operation.
As shown in Figure 3, three-phase five-wire mode 380VAC power supply is exported a road 24VDC by the input of live wire He Yi road, Qu Yi road zero line by 24VDC power module and is powered, four phase five-wire system 560VDC, 24VDC power supply band 24VDC power supply itself.Two-way 24VDC power supply is switched by three switch knobs.
As shown in Figure 1, system initial state is that four phase five-wire system 560VDC, 24VDC circuit and the duplex feeding of three-phase five-wire mode 380VAC circuit are not worked, and three switch knobs are in position 0, and the two-way indicator light that powers on all extinguishes.Wherein,
Position 0: sky;
Position 1: three-phase five-wire mode 380VAC circuit;
2: the four phase five-wire system 560VDC in position, 24VDC circuit.
When three switch knobs are switched to position 1, system is three-phase five-wire mode 380VAC line work pattern, and the three-phase five-wire mode 380VAC circuit indicator light that powers on is bright.
When three switch knobs are switched to position 2, system is four phase five-wire system 560VDC, 24VDC line work pattern, and four phase five-wire system 560VDC, the 24VDC circuit indicator light that powers on is bright.
When equipment is in an emergency or moves, break down, when needing emergency power off, take the anxious under-voltage button power-off that stops.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
