Description
Technical field
The utility model relates to field of electrical equipment, especially relates to a kind of cable fault detect device.
Background technology
Electric cable failure detector is a set of comprehensive cable failure detection instrument device.Can to the high resistant arcing fault of cable, high low-resistivity ground connection, the broken string of short circuit and cable, the faults such as loose contact are tested, if be equipped with sound detection fixed point apparatus, can the exact position of Accurate Determining trouble spot.Be specially adapted to test various model, the power cable of different brackets voltage and telecommunication cable.Existing electric cable failure detector is subject to the interference of environmental factor and affects measuring accuracy when using, and build is comparatively large, installs loaded down with trivial details, complicated operation.
Summary of the invention
The purpose of this utility model is to provide a kind of electric cable failure detector, rapidly simple to operate, fast and accurately failure judgement.
The utility model solves the technical scheme that its technical matters adopts: a kind of cable fault detect device, comprise second pulse generator, second pulse generator one end connecting integration high pressure generator, one end connects failure cable, second pulse generator is stube cable failure tester also, be provided with reservoir and display screen in electric cable failure detector, in second pulse generator, be provided with second pulse automatic initiating device.
In a preferred embodiment of the present utility model, the high pressure entry of integrated high-pressure generator connecting secondary pulse producer, the high-pressure outlet of failure cable connecting integration high pressure generator.
The beneficial effects of the utility model are: after adopting said structure, fault waveform is simplified, the impacting with high pressure flashover waveform of complexity is become the short trouble waveform being similar to Low Voltage Impulse Method of very easy interpretation, reduce the technical requirement to operating personnel and experience, improve field failure judging nicety rate, realize accurate interpretation waveform, demarcate fault distance, reach the object of quick and precisely test cable fault, fault test technology is made to reach top level, product adopts the true colour display screen of super large to show touch screen, waveform display is clear especially, adopt definition sharp screen analogue-key, operate very simple.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
A kind of cable fault detect device as shown in Figure 1, comprise second pulse generator 1, second pulse generator 1 one end connecting integration high pressure generator 2, one end connects failure cable 3, stube cable failure tester 4 gone back by second pulse generator 1, be provided with reservoir 7 and display screen 8 in electric cable failure detector, in second pulse generator 1, be provided with second pulse automatic initiating device; The high pressure entry 5 of integrated high-pressure generator 2 connecting secondary pulse producer 1, the high-pressure outlet 6 of failure cable 3 connecting integration high pressure generator 2.
During test failure cable, the temporary impact high-voltage pulse that integrated high-pressure generator produces is guided on the fault phase of failure cable, ensure that trouble spot can fully puncture, and can extend fault puncture after arc duration, simultaneously, produce a trigger pulse and start second pulse automatic initiating device and electric cable failure detector, second pulse automatic initiating device successively sends two test action of low-voltage pulse immediately, be sent on tested failure cable through integrated high-pressure generator, utilize the current/voltage after cable breakdown, waveform character, by diverse for formation two reflected impulse record on a display screen, instrument failure display waveform is very simple, the total length of a pulse waveform reflection cable, high resistant (short circuit) fault distance of another pulse waveform reflection cable, any high resistive fault waveform all has the feature of short trouble waveform, total length waveform and fault waveform Display on the same screen and with shielding contrast, anyone can quick and precisely failure judgement distance.
Adopt international state-of-the-art " second pulse " measuring technology, traditional impulse HV flashover method and action of low-voltage pulse technology are combined, adapt to wide, the automatic display of the transmission of products application second pulse and fault reflected signal, make the expression of fault signature waveform very simple, high resistive fault waveform is made only to have one, i.e. the short trouble waveform of similar Low Voltage Impulse Method; The simultaneously setting of reservoir, by on-the-spot test to waveform be stored in easily in instrument by regulation order, observe for random call, store a large amount of on-the-spot test waveforms; Super large liquid crystal display is display terminal, waveform of the trouble spot waveform recorded and the total length of good phase being opened a way, and is simultaneously displayed on screen and carries out, with screen contrast and superposition contrast, fault distance being judged more accurate.
Electric cable failure detector has user-friendly software and full menu in Chinese, realizes man-machine conversation, and use simple to operate, reliability is high, method of testing simple and fast; Have powerful data processing function, private database can store any number of test result.Cable fault detect device has extremely safe sampling high voltage protective, quarantine measures, and testing tool can not crash and damage in rated impulse voltage environment.Measuring accuracy and convenient test degree are better than domestic and international any checkout equipment of the same race, and detection failure success ratio.Electric cable failure detector has standard USB interface, connects printer, QWERTY keyboard, USB flash disk and carry out equipment software upgrading by interface.Electric cable failure detector itself has built-in power, without the open circuit of test cable under electrical environment and low-resistance short trouble.
It is emphasized that: the foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
