Specific embodiment
The present invention is further described with reference to the accompanying drawing:
A kind of floating ring formula liquid electrostatic test macro as shown in Figure 1, including hollow Insulation test pipe, conducting wire 4, electrode 6,
Contactless electrostatic tester 7, which is characterized in that the hollow Insulation test tube top portion is equipped with top cover 1,1 lower section of top cover
Equipped with floating ring 2, multiple through-holes are machined on the tube wall of the hollow Insulation test pipe, the conducting wire 4 by being pierced by through-hole, and
Each through hole is welded with metal measuring point 3；After the other end of the conducting wire 4 is drawn from 5 bottom of hollow tube, with each electrode slice 6
It is connected, each metal measuring point 3 is connected to an electrode slice by a conducting wire；Electrode slice 6 and contactless electrostatic tester 7
Optimum distance is kept, and is fixed on the base.The electrode slice 6 and contactless electrostatic tester 7 are according to contactless electrostatic
The operation instruction of tester determines, possible different using different electrostatic tester distances.
The hollow tube 5 is formed with aluminium product, and groove and through-hole are processed at the position for arranging each metal measuring point 3, recessed
The depth of slot is slightly larger than the thickness of metal measuring point, and through-hole diameter is slightly larger than the diameter of solid conductor.The effect of groove is to make metal
Measuring point 3 does not protrude into other than side after being installed to 5 tube wall of hollow tube, to prevent the movement to floating ring 2 from causing to hinder；The work of through-hole
With being to be pierced by conducting wire therefrom to be welded to metal measuring point.Oxidation processes are carried out after the completion of the machining of hollow tube 5, are allowed into
For insulator, impacted to prevent the electrostatic measurement to a measuring point.It is then applied with top cover 1 using being threadedly engaged at the top of hollow tube
Electric insulating sealant is covered, so as to the fixed conducting wire being connected with metal measuring point on floating ring 2, and prevents testing liquid from entering in hollow tube
Portion.
It is fixed with electric insulating sealant between the metal measuring point 3, floating ring 2 and hollow tube 5.
The conducting wire being connected with the metal measuring point 3 on 5 tube wall of hollow tube is pierced by from the through-hole in groove and is welded to gold
Belong to the back of measuring point 3；It need to be pierced by from 1 central through hole of top cover with the conducting wire that metal measuring point is connected on floating ring 2, conductor length is suitable
When the movement of floating ring 2 cannot be limited.After conducting wire is drawn from hollow tube bottom, electric insulating sealant is used to hollow tube bottom opening
Sealing, prevents conducting wire to be broken or snap due to by external force, and prevent testing liquid from entering hollow tube to fix conducting wire.
The floating ring 2 is made of lightweight resin, and is made hollow, guarantees to float on liquid level to mitigate weight.
After conducting wire 4 is drawn from hollow tube bottom, the other end is connected with each electrode slice 6, each metal measuring point passes through one
Root conducting wire is connected to an electrode slice.Electrode slice 6 and contactless electrostatic tester 7 keep optimum distance and are fixed on pedestal 8
On, pedestal is isolation material, is influenced each other to prevent each electrode slice institute is electrically charged.Each electrostatic tester 7 is grounded.
When test, testing tube is put into testing liquid vertically, and connects circuit by diagram, opens electrostatic tester 7
Power switch be the electrostatic potential that measuring point can be read.By circuit connection, each electrode slice and corresponding metal are surveyed
Point forms equipotentiality body, and since metal measuring point is directly contacted with testing liquid, potential is equal with the potential in liquid, therefore passes through
The electrostatic potential in the liquid of corresponding position can be obtained in the potential of measuring electrode sheet.Since floating ring 2 floats on liquid level always,
Therefore the reading for the electrostatic tester being connected with metal measuring point on floating ring 2 is the electrostatic potential of liquid level.With other metal measuring points
The reading for the electrostatic tester being connected respectively corresponds the electrostatic potential at different depth in liquid.
In addition, the number of different test tube materials, size and metal measuring point can be designed according to industry different demands.
