Description
Technical field
The utility model relates to a kind of ground connection electrode resistance on-Line Monitor Devices.
Background technique
Buildings in general is both provided with earthing pole, it is therefore an objective to the electric current that thunder and lightning generates is guided to the earth by earthing pole, from
And play the role of protection.In the prior art, the resistance measurement method of earthing pole includes two, three, four line ground connection methods etc., but
Measurement method above-mentioned at present is both needed to that the measurement that corresponding current or voltage carries out ground resistance is added, especially when in measurement oil gas
When the ground connection electrode resistance of the inflammable and explosive occasion such as accumulator tank, being measured using the above method can be with certain risk, tool
There is security risk, therefore, it is necessary to a kind of instruments of the ground connection electrode resistance of the inflammable and explosive occasions such as energy security measurement oil gas accumulator tank.
Summary of the invention
For overcome the deficiencies in the prior art, the utility model provides a kind of new-type ground connection electrode resistance on-Line Monitor Device.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of ground connection electrode resistance on-Line Monitor Device, including on-line monitoring instrument, back-end data processor and ground stud,
The ground stud is four four vertex dispersed placements that parallelogram is pressed as the four grounded pole of A, B, C, D, wherein A, B
It is connected with conducting wire between two points ground fault stake, and ground connection object is connected by conducting wire；The on-line monitoring instrument connects C, D two o'clock
Ground pile carries out energization measurement, and the data measured are converted by back-end data processor, the two points ground fault stake of real-time display A, B
Between grounding resistance.
The parallelogram angle that described ground connection pole A, B, C, D are constituted is right angle.
The distance between described A, B two o'clock is greater than or equal to 50 meters.
Earth mat is respectively equipped at the ground stud of A, B two o'clock, C, D two points ground fault stake setting is laid with range in earth mat
Outside.
The on-line monitoring instrument includes alarm module.
The beneficial effects of the utility model are: by four grounded stake as the four grounded pole of A, B, C, D, it is four grounded
Pole is distributed by four vertex of parallelogram, and the distance between A, B point is equal with the distance between C, D point, connects
When ground object, through a long time measure A, B ground connection pole ground stud between average resistance and C, D ground connection pole ground stud it
Between average resistance, and the ratio both being calculated is poor, is grounded object when passing through conducting wire connection between A, B two points ground fault stake, into
When the measurement of row grounding resistance, energization measurement is carried out by ground stud of the on-line monitoring instrument to C, D two o'clock, the number measured
It converts according to by back-end data processor, obtains and show the ground resistance reference value between A, B two points ground fault stake in real time,
To which the resistance value for being grounded pole to A, B two carries out assessment monitoring, Permanent Reference measuring electrode, nothing are made with C, D two points ground fault stake
It needs that the measurement that corresponding current or voltage carries out ground connection electrode resistance directly is added to A, B two points ground fault stake, solves in measurement oil gas
Existing security risk when the ground connection electrode resistance of the inflammable and explosive occasion such as accumulator tank.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples.
The structural schematic diagram of Fig. 1 the utility model.
Specific embodiment
A kind of ground connection electrode resistance on-Line Monitor Device referring to Fig.1, including on-line monitoring instrument 4, back-end data processor 5
And ground stud 3, ground stud 3 is four and as the four grounded pole of A, B, C, D, is grounded pole A, B, C, D and presses parallel four side
Four vertex dispersed placements of shape are wherein connected with conducting wire 2, and pass through the connection ground connection object of conducting wire 2 between the stake of A, B two points ground fault
1；In not connected ground connection object 1, through a long time survey calculation obtain the average resistance between A, B two points ground fault stake be x and
C, the average resistance between the stake of D two points ground fault is y, show that the ratio coefficient of the two is x/y；When A, B two o'clock need to be measured immediately
When the grounding resistance of ground stud, grounding resistance y1 is measured to corresponding current or voltage is added between C, D two points ground fault stake,
The grounding resistance y1 and ratio coefficient x/y of C, D the two points ground fault stake measured are multiplied connecing to get A, B two points ground fault stake out
Ground resistance reference value x1.
As a preferred embodiment of the present invention, the parallelogram angle that ground connection pole A, B, C, D is constituted is right angle, structure
At a square or rectangular, measuring result error at this time is smaller；According to the rules, the distance between two ground connection poles must be big
In or be equal to 50 meters, i.e. A, B is grounded the distance between pole and is greater than or equal to 50 meters, is just able to achieve correct grounding resistance and surveys
Amount.
A, earth mat 6 is respectively equipped at the ground stud of B two o'clock, 6 energy total number of earth mat spreads lightning current or lightning wave, electrostatic
It is directed at earth medium, reaches better lightning protection effect, and C, D two points ground fault stake setting are laid with outside range in earth mat 6.
Preferably, on-line monitoring instrument 4 includes alarm module, according to national regulation, be grounded electrode resistance need to be less than or
Equal to 4 Ω, therefore, when back-end data processor 5 converses the numerical value come close to when being even greater than 4 Ω, transmission signal is enabled immediately
The alarm module of on-line monitoring instrument 4 issues alarm signal, and staff is reminded to detect.
