Abstract
The utility model discloses a copper line pin hole detection apparatus, comprising a DC power supply meter and ionogenic detection solution placed in a water tank. The cathode of the DC power supply meter is in connection with two peeled ends of a copper line to be detected; a part between two ends of the copper line to be detected is immersed in the detection solution; the anode of the DC power supply meter is in electric communication with the detection solution. The detection apparatus of the utility model is simple and can fast, simply, visually, clearly and accurately detect whether pin holes exist on the copper line so as to determine whether the cash line has skin film damaged and further to examine and determine paint film adhesiveness.
Description
Technical field
The present invention relates to a kind of copper cash epithelium pick-up unit, belong to the detection technique field.
Background technology
All use enameled wire, winding wire etc. in transformer and a lot of equipment; These lines are the copper cash that has insulating coating; If the copper cash epithelium is impaired, have pin hole, will be because of the electrical specification of its product of processing of copper wires epithelium harmful effect, therefore; Before using copper wires, must be to copper wires epithelium intact detection the whether.
Summary of the invention
Technical matters to be solved by this invention provides a kind of copper cash pin hole pick-up unit, is used to detect copper wires and whether has the epithelium damaged phenomenon.
For solving the problems of the technologies described above; The present invention provides a kind of copper cash pin hole pick-up unit; It is characterized in that comprise the direct supply meter, place the ionogenic detection solution in the tank, said direct supply meter negative pole is connected with the two ends of the peeling of a copper wires to be checked; Part between the copper wires to be checked two ends immerses in the said detection solution, the anodal and said detection solution electric connection of said direct supply meter.
The WV of said direct supply meter is 12V.
Said direct supply meter is anodal to be connected with a conductive structure one end, and the said conductive structure other end places said detection solution.
Said direct supply meter positive pole directly places said detection solution.
Copper cash pin hole detection method, the detection step is:
At first, make copper wires to be checked two ends expose copper cash, direct supply meter negative pole is clamped the two ends copper cash of wire rod to be checked, immerse in the middle of the copper wires and detect in the solution, simultaneously, direct supply meter positive pole is also put into the detection solution of tank;
Secondly, said connection direct supply meter is regulated direct supply meter voltage DC=12V;
At last, observe immersing the copper wires surface in the said detection solution, is that epithelium breaks if the purple bubble appears in copper wires, and a place is a pin hole, if copper wires purple bubble or bubble do not occur in specification the time, judges that copper wires is qualified.
Said detection solution is the potpourri of tap water, Nacl, phenolphthalein, alcohol.
The mass ratio of phenolphthalein and alcohol is between the 1:10-1:6 in the said detection solution.
The mass ratio of Nacl and tap water is 1:800-1:1200 in the said detection solution.
After said detection solution has just prepared back or use; The step that also comprises regular its validity of detection: get a copper cash and remove insulated hull; The two ends that direct supply meter negative pole is clamped copper cash; Part between the copper cash two ends immerses and detects in the solution, and simultaneously, direct supply meter positive pole is also put into and detected solution; Connect the direct supply meter, regulate direct supply meter voltage DC=12V, observe the variation that detects solution, if
A. detect the solution becomes redness: detect solution and effectively can use;
B. detect the solution nondiscolouring: detect solution and lost efficacy the detection solution that more renews;
C. it is identical with the color that produces bubble to detect solution colour: the detection solution that more renews.
The beneficial effect that the present invention reached:
Pick-up unit of the present invention is simple and easy, can detect quick, simple, intuitive, clear, exactly whether pin hole is arranged on the copper cash, whether has the impaired phenomenon of epithelium thereby judge copper wires, and then the paint film tack is judged in check.
Description of drawings
Fig. 1 is a pick-up unit synoptic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.Following examples only are used for technical scheme of the present invention more clearly is described, and can not limit protection scope of the present invention with this.
As shown in Figure 1; Copper cash pin hole pick-up unit of the present invention comprises direct supply meter 1, places the detection solution 3 of tank 2; Remove copper wires to be checked 4 two ends 41 scolding tin, epithelium,, immerse in the middle of the wire rod and detect in the solution 3 two ends 41 that direct supply meter 1 negative pole 11 is clamped wire rod to be checked; Simultaneously, direct supply meter 1 anodal 12 is also put into the detection solution 3 of tank.
Duan Houru does the validity of pin hole detection test preceding palpus redistribution solution or test detection solution 3 every month for the first time at regular intervals, and detecting solution 3 is the potpourri of 1000ml tap water, 1g Nacl, 1.02g phenolphthalein, 10ml alcohol formation.
The allocation process that detects solution 3 is:
(1) contains the 1000ml tap water with measuring cup and pour in the tank 2, add Nacl 1g simultaneously;
(2) take out phenolphthalein 1.02g, make the special-purpose spoon of medication powder put into measuring cup, splash into 10ml alcohol, shake up and pour in the tank;
Detect solution 3 and prepare the back or do pin hole every month for the first time when detecting, must test the validity that detects solution with the peeling copper cash.Its process is:
Direct supply meter negative pole is clamped peeling copper cash two ends, immerse in the middle of the copper cash and detect in the solution, simultaneously, direct supply meter positive pole is also put into and is detected solution; Connect the direct supply meter, regulate direct supply meter voltage DC=12V.At this moment, observe the variation that detects solution, if
A. detect the solution becomes redness: detect solution electrolytic reaction has taken place, generate H
2And OH
-, phenolphthalein is met OH
-Redden, explain that detecting solution effectively can use;
B. detect the solution nondiscolouring: explain that detecting solution does not react, lost efficacy, must discard old solution, the detection solution that more renews;
C. it is identical with the color that produces bubble to detect solution colour: the generation electrolytic reaction has been described, but owing to alcohol, water volatilization, phenolphthalein separates, and causes electrolytic reaction incomplete, phenomenon is not obvious, and need change solution this moment immediately.
After definite detection solution to be detected can be used, can begin the epithelium of copper wires is carried out the pin hole detection.
The detection step is:
At first, remove copper wires to be checked 4 two ends 41 scolding tin, epithelium, direct supply meter 1 negative pole 11 is clamped the two ends 41 of copper wires 4 to be checked, immerse in the middle of the copper wires 4 and detect in the solution 3, simultaneously, direct supply meter 1 anodal 12 is also put into the detection solution 3 of tank 2.
Secondly, connect direct supply meter 1, regulate direct supply meter 1 voltage DC=12V.
At last, observe to immerse detecting copper wires 4 surfaces in the solution 3, is that epithelium breaks if the purple bubble appears in copper wires 4 surfaces, and a place is a pin hole, if copper wires 4 surfaces purple bubble or bubble do not occur in specification the time, judges that copper wires 4 is qualified.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from know-why of the present invention; Can also make some improvement and distortion, these improvement and distortion also should be regarded as protection scope of the present invention.
