Description
Technical field
The utility model belongs to power transformation technology field, is specifically related to transformer voltage wireless measurement device.
Background technology
The current voltage of transformer both sides or the test of current value, normally undertaken measuring by mutual inductor, there is following weak point in this measuring method: one is need mutual inductor to access in the circuit of transformer, affects to some extent transformer capacity; Two is impacts that measuring accuracy is subject to mutual inductor precision; Three is mutual inductor critical pieces as measuring equipment, and its acquisition cost, maintenance cost are higher; Although four is that the electric isolation that had magnetic circuit to carry out measured by mutual inductor, for operating personnel, still there is certain potential safety hazard.
Summary of the invention
The purpose of this utility model solves prior art Problems existing, provides and sampled by transformer operational factor such as magnitude of voltage, the wireless test sampling circle device read through wireless transmission to operation pulpit or the enterprising line parameter of administration and supervision authorities microcomputer.
The utility model is solve the problems of the technologies described above the technical scheme taked to be:
Transformer voltage wireless measurement device, comprises transformer magnetic circuit, is characterized in: also comprise voltage sampling device, and described voltage sampling device is by lonely circle coil, analog-digital commutator and wireless launcher assembly; Described lonely circle coil is around on magnetic circuit, near tested former limit or secondary coil, access analog-digital commutator between the two ends of lonely circle coil, the output termination wireless launcher of analog-digital commutator, the induced voltage numerical value in lonely circle coil is transmitted into receiving trap through wireless launcher.
Described lonely circle coil around the internal layer of primary coil or secondary coil or skin, described lonely circle coil several, be distributed on magnetic circuit.
The utility model compared with prior art, has following beneficial effect:
The utility model adopts built-in voltage sampler, and by analog to digital conversion by data transfer to receiving trap, the measurement cost of transformer voltage is greatly reduced, decrease the power consumption link that error is caused in centre, measuring accuracy significantly improves, and improve safety in production coefficient, particularly eliminate mutual inductor and decrease cost, corresponding corrective maintenance maintenance workload reduces the artificial of saving.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-lonely circle coil; 2-magnetic circuit; 3-analog to digital conversion and wireless launcher assembly; 4-primary coil; 5-secondary coil.
Embodiment
As shown in Figure 1, transformer voltage wireless measurement device, comprises transformer magnetic circuit 2, also comprises voltage sampling device, and described voltage sampling device is by lonely circle coil 1, analog-digital commutator and wireless launcher assembly 3; Described lonely circle coil 1 is around on magnetic circuit 2, near tested primary coil 4 or secondary coil 5, analog-digital commutator is accessed between the two ends of lonely circle coil 1, the output termination wireless launcher of analog-digital commutator, the form of the induced voltage numerical value digital signal in lonely circle coil 1 is transmitted into receiving trap through wireless launcher.
Described lonely circle coil 1 around the internal layer of primary coil 4 or secondary coil 5 or skin, described lonely circle coil 1 several, be distributed on magnetic circuit 2.
the course of work and principle:
During utility model works, described lonely circle coil 1 induced potential converts induced potential to digital signal through analog-digital commutator, through wireless launcher by digital signal transmission on receiving trap, thus operating personnel read data, or utilize and receive signal and carry out Automated condtrol.Several lonely circle coils 1 are arranged on magnetic circuit 2, and with the accuracy of guarantee information transmission and security, what cause to prevent voltage sampling device fault misreads, judges by accident.
