Description

A kind of grounding net of transformer substation test electrode position indicator based on Global Satellite Navigation System
Technical field
It is that a kind of grounding net of transformer substation test electrode based on Global Satellite Navigation System is fixed the present invention relates to the communications field Position instrument can determine potential pole and electric current pole piling position in grounding net of transformer substation resistance test by Global Satellite Navigation System It sets.
Background technique
The position of potential pole and electric current pole when electrode positioning of the present invention refers to determining grounding net of transformer substation resistance measurement It sets, i.e. the pile driving position of voltage stake and electric current stake, stake point position, which is chosen, sees Fig. 1.
Calculate grounding net of transformer substation resistance when need to measure potential pole to earthing or grounding means linear distance dPGIt is arrived with electric current pole The linear distance d of earthing or grounding meansCGAnd the data such as angle theta between two straight lines, in conjunction with what is shown on ground screen resistance testing instrument Voltage value and current value are calculated using impedance ground formula (1) and (2), and measurement wiring diagram is shown in Fig. 2, impedance ground formula:
In formula:
Z '-impedance ground;
U-current potential stake is to the voltage between earthing or grounding means;
Ig-flows through the electric current of testing current lead;
The angle of θ-current line and equipotential line;
Z-impedance ground correction value;
D-grounded screen catercorner length.
Usual electric current stake C and subject earthing or grounding means edge distance dCGIt should be 4~5 times of earth mat catercorner length D, when remote When having any problem apart from unwrapping wire, in the uniform area d of soil resistivityCGDesirable 2D, in the desirable 3D in the uneven area of soil resistivity;Electricity Position stake P and subject earthing or grounding means edge distance dPGFor (50%~60%) dCG.In unwrapping wire, current feed and voltage should be made Lead keeps distance remote as far as possible, to reduce influence of the electromagnetic coupling to test result.When in-site measurement, potential pole and electric current pole It is mainly measured to the angle between the linear distance of earthing or grounding means and two straight lines by two ways, first is that according to live reference Object estimation, second is that by theodolite accurate measurement, but all there is technological deficiencies for either way:
(1) mode for carrying out distance and angle estimation according to live object of reference is more universal, with being chiefly used in active service substation The regular inspection of net resistance.It is required according to " DL/T475-2017 earthing or grounding means characterisitic parameter measures directive/guide ", electric current stake and subject are grounded The distance at device edge is 4~5 times of earth mat catercorner length D, even uniformly the regional distance is also at least for soil resistivity Should be in 2D~3D, for 220kV substation, which is 1000~2000 meters or even farther, voltage stake and subject earthing or grounding means It is larger to estimate numerical bias also close to km for the distance at edge.In addition, angle theta between two straight lines is close to 300When measurement result 30 are determined closest to true value, but by estimating0Line between angle deviation also can be very big.Therefore, the estimation of multiple parameters It substitutes into formula to be calculated and will substantially reduce the accuracy of measurement result, accurate judgement cannot be made to mesh grounding situation.
(2) using theodolite precise measurement be used cooperatively by theodolite and Sopwith staff, can with the stake of precise measurement current potential and To data such as angle thetas between the linear distance of earthing or grounding means and two straight lines, computational solution precision is high for electric current stake.But due to existing Service substation equipment interval is more, and intervisibility is poor, and safe distance requires strictly, to be unfavorable for setting up Sopwith staff, therefore, the method is only fitted The newly-built substation good and in the infrastructure stage for intervisibility.
(3) newest publication revised edition " DL/T475-2017 earthing or grounding means characterisitic parameter measures directive/guide " requires, giant ground For device earth loop impedance test after the completion of commissioning test, the impedance ground of test in suitable 5~6 years, the prior art is unable to satisfy change The repeatability of all previous measured position of accuracy and same substation of power station earth mat resistance measurement work.
Based on the above-mentioned condition of substation ground network resistance measurement, can be significantly improved using Global Satellite Navigation System positioning Potential pole and electric current pole are protected to the computational accuracy of the angle between the linear distance of earthing or grounding means and two straight lines in measurement process Card wiring meets testing standard requirement, and is routed personnel convenient for accurate selection electric current pole and potential pole position.The present invention will be significant It improves power transformation and transports inspection the worker safety of operating process and accuracy of measurement result when measuring earth mat resistance.
