The invention will be further described below in conjunction with accompanying drawing and specific embodiment:
A kind of power cable equipment is to the core device, as shown in Figure 1, comprising: electric resistance partial pressure module, voltage acquisition module and logical operation module three parts, the electric resistance partial pressure module comprises electric resistance partial pressure plate 2, upper connecting terminal 4, resistance 3, described upper connecting terminal 4 is installed on the electric resistance partial pressure plate 2, the resistance series connection that described resistance 3 equates for several resistances, be installed on the electric resistance partial pressure plate 2, and being its power supply by direct supply 1, the two ends extension line of each resistance 3 is received on the described upper connecting terminal 4; Described voltage acquisition module comprises voltage acquisition plate 11, lower connecting terminal 6 and voltage sensor 7, and lower connecting terminal 6 and voltage sensor 7 are installed on the voltage acquisition plate 11, and the wiring on the lower connecting terminal 6 is received above the voltage sensor 7; Described logical operation module comprises core control panel 10, processor 8 and liquid crystal display 9, processor 8 and liquid crystal display 9 are installed on the core control panel 10, the wiring of described voltage sensor 7 is received on the processor 8, the voltage signal that processor 8 is sent voltage sensor 7 here is processed, and the result is presented on the liquid crystal display 9.
To the core device, its characteristics are according to above-mentioned power cable equipment: described power cable equipment is designed with shell to the core device, and sheathing material selects epoxy resin board to make.
Each several part structure of the present invention forms running parameter and analysis:
Among the principle of the invention figure as shown in Figure 1, the present invention is divided into three parts: electric resistance partial pressure module, voltage acquisition module and DSP are the logical operation module of processor.The below will introduce its course of work (supposing that secondary cable has n root line) in detail.
The electric resistance partial pressure module: connected by the resistance that n-1 resistance equates, and by direct supply V
DCBe its power supply.And receive on the connection terminal 3 (guiding to the total n root of voltage acquisition line on the connection terminal 3) at the two ends of each resistance extension line, the n root core in the secondary cable is received on the connection terminal respectively.
Secondary cable: the core of secondary cable one end is received on the connection terminal of electric resistance partial pressure module and is determined the numbering of every core; The other end of secondary cable is received on the connection terminal of voltage acquisition plate.
Voltage acquisition module: the voltage acquisition plate is comprised of n-1 direct current voltage sensor, and the positive ends of each sensor is by connecting (representing with thick line in the drawings) with single line.And remaining n-2 root line is received respectively the negative polarity end of each voltage sensor.
Logic processing module: core control panel is to be that development board and the LCDs of core processor consists of by DSP.The voltage signal that DSP collects voltage sensor carries out computing and logic to be judged, calculates secondary core on the voltage acquisition plate corresponding to the sequence number of its opposite side, and is presented on the liquid crystal display in order.Concrete calculating process is as follows:
At first the voltage U i that collects is judged whether greater than zero, and recording voltage is greater than zero number.If n-1 value arranged greater than zero, then be connected on the first piece core of the corresponding secondary cable of concentric line on the electric resistance partial pressure module on voltage sensor 6 positive poles.If i value in like manner arranged greater than zero, then the concentric line on the voltage sensor positive polarity is with regard to the n-i root core of corresponding secondary cable on the electric resistance partial pressure module.
Suppose that the front judges the n-i root core of the corresponding secondary cable of concentric line of voltage sensor 6.Because n-i root core is received the positive ends of all voltage sensors as concentric line, the voltage that then 1 to n-i-1 root core of correspondence secondary cable collects when n-i 〉=2 is negative voltage; The voltage that n-i+1 to the n root core of corresponding secondary cable collects is positive voltage.
The negative voltage that voltage sensor collects can be defined as U1 on the electric resistance partial pressure module, U2 according to the electric resistance partial pressure principle arranged sequentially afterwards according to descending ... U n-i-1,1 of corresponding secondary core to n-i-1 root core respectively.
In like manner, the positive voltage that collects for voltage sensor 6 can determine that according to descending arranged sequentially the n-i+1 of secondary core is to n root core.
So far, the core of secondary cable is all found out, and then shows in order by the communication with liquid crystal display 8.
