Abstract
The patent relates to power element detecting equipment, and in particular relates to a power element detecting device. The power element detecting device is composed of a sound wave generator, a sound wave collector, a signal conversion circuit and a mobile computer, wherein the sound wave generator and the sound wave collector are respectively connected with the signal conversion circuit, and the signal conversion circuit is connected with the mobile computer. The power element detecting device has the advantage that the state of a power element can be accurately detected without contacting the power element and turning off the electricity in completely different ways.
Description
Technical field
This patent relates to the force device checkout equipment, is specially a kind of force device pick-up unit.
Background technology
Existing force device detects all to be needed grid cut-off, separately force device is detected.Such technology continues operation to electrical network and forms pressure.It is to be undertaken by faradic mode that live monitoring equipment is separately arranged, and has very large potential safety hazard.Electric power operation department is perplexed in the detection of force device all the time.
Summary of the invention
This patent, for above technical matters, provides a kind of force device pick-up unit.
The concrete technical scheme of this patent is as follows:
The force device pick-up unit, be comprised of sonic generator, sound collecting device, signaling conversion circuit, removable computer, and sonic generator, sound collecting device connect respectively signaling conversion circuit, and signaling conversion circuit connects removable computer.
sonic generator sends the sound wave of certain frequency according to the instruction of removable computer, sonic generator to as if detected charged work about electric power element, the frequency that removable computer is set is to answer the frequency of tool and the data of fault element frequency according to normal component, under the correct frequency sound wave, the non-fault element will send the resonant frequency sound wave of concord, the sound collecting device gathers acoustic signals after sonic generator stops sending acoustic signals, the acoustic signals that the sound collecting device obtains is delivered to removable computer by signaling conversion circuit and compares, if there are huge deviation in signal frequency and the comparable data of replying, show force device and have fault, frequency range in load database is that equipment shows normally.The advantage of this patent is embodied in, and, by diverse mode, does not contact force device, does not cut off the power supply and also can accurately detect the state of force device.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, 1---sonic generator, 2---sound collecting device, 3---the tested force device of signaling conversion circuit, 4---removable computer, 5---.
Embodiment
This is described further this patent below in conjunction with embodiment and Figure of description.
The force device pick-up unit, be comprised of sonic generator, sound collecting device, signaling conversion circuit, removable computer, and sonic generator, sound collecting device connect respectively signaling conversion circuit, and signaling conversion circuit connects removable computer.
sonic generator sends the sound wave of certain frequency according to the instruction of removable computer, sonic generator to as if detected charged work about electric power element, the frequency that removable computer is set is to answer the frequency of tool and the data of fault element frequency according to normal component, under the correct frequency sound wave, the non-fault element will send the resonant frequency sound wave of concord, the sound collecting device gathers acoustic signals after sonic generator stops sending acoustic signals, the acoustic signals that the sound collecting device obtains is delivered to removable computer by signaling conversion circuit and compares, if there are huge deviation in signal frequency and the comparable data of replying, show force device and have fault, frequency range in load database is that equipment shows normally.The resonant frequency of different elements is different, and under normal condition, the resonant frequency of unified element is consistent,, if there is extremely, can show tentatively that force device has fault, needs further to determine and maintenance.
Claims (1)
1. the force device pick-up unit, be comprised of sonic generator, sound collecting device, signaling conversion circuit, removable computer, it is characterized in that: sonic generator, sound collecting device connect respectively signaling conversion circuit, and signaling conversion circuit connects removable computer.
