Description

A kind of distribution network failure recognition device

Technical field

The utility model relates to a kind of distribution network failure recognition device.

Background technology

Along with the large-scale production of electric power, the structure that is applied to the power equipment of power distribution network becomes increasingly complex, in case certain part of equipment breaks down in operation process, just breaks in production probably causes enormous economic loss, even the consequence of bringing on a disaster property.At present, traditional approach is pressed in the location of power network line fault section; Blindly hunting, during handling failure, seek scope is too wide at the scene for the operations staff; Can't find the trouble spot accurately immediately, even and find the trouble spot, can not confirm the type and the severity of fault soon; After confirming, just can fix a breakdown inefficiency.

Summary of the invention

The purpose of the utility model is to overcome the defective of prior art and kind of a distribution network failure recognition device is provided, and can monitor the information about power of trouble spot automatically, and through to the information about power analysis, confirms the type and the severity level of fault.

The technical scheme that realizes above-mentioned purpose is:

A kind of distribution network failure recognition device, external host computer, said Fault Identification device comprise wave filter, amplifier, analog to digital converter and microprocessor, touch-screen and the storer of voltage transformer (VT), current transformer, connection successively, wherein:

Said voltage transformer (VT) summation current transformer connects said wave filter respectively;

Said microprocessor connects said touch-screen, storer and host computer respectively.

The beneficial effect of the utility model is: the utility model can be monitored the information about power of trouble spot automatically, and through to the information about power analysis, confirms the type and the severity level of fault, need not artificially confirm fault to have improved maintenance efficiency greatly.

Description of drawings

Fig. 1 is the structural drawing of the distribution network failure recognition device of the utility model.

Embodiment

To combine accompanying drawing that the utility model is described further below.

See also Fig. 1; The distribution network failure recognition device of the utility model; External host computer 20, said Fault Identification device comprise wave filter 3, amplifier 4, analog to digital converter 5 and microprocessor 6, touch-screen 7 and the storer 8 of voltage transformer (VT) 1, current transformer 2, connection successively, wherein:

Voltage transformer (VT) 1 summation current transformer 2 connects wave filter 3 respectively;

Microprocessor 6 connects touch-screen 7, storer 8 and host computer 20 respectively.

The principle of work of the utility model: voltage transformer (VT) 1 summation current transformer 2 is gathered the information about power of a certain power equipment in the power distribution network; Be voltage and current information; And after wave filter 3 filtering, amplifier 4 amplifications and analog to digital converter 5 conversions, pass to microprocessor 6 successively, the information of 6 pairs of receptions of microprocessor is carried out analyzing and processing, and according to storer 8 stored history; Judge fault category, and the result that will obtain deposits storer 8 in.Touch-screen 7 is realized man-machine interaction, and host computer 20 is used for information is done further processing, to reach the purpose of identification fault better.

Each parts of the utility model all select for use market product commonly used to realize.

Above embodiment only supplies to explain the usefulness of the utility model; But not to the restriction of the utility model; The technician in relevant technologies field under the situation of spirit that does not break away from the utility model and scope, can also make various conversion or modification; Therefore all technical schemes that are equal to also should belong to the category of the utility model, should be limited each claim.
