Description

Technical Field

[0001] The utility model belongs to the technical field of membrane material detection equipment, and in particular relates to an online detection mechanism for electrical weak points of membrane materials. Background Art

[0002] The membrane material electrical weakness detection mechanism is a device that collects the leakage current generated by a mutation at a certain point of the membrane material in the high-voltage circuit, that is, tests the electrical weakness of the film. It mainly includes a ring-unwinding roller, a grounding roller, a conductive rubber mechanism and a ring-rewinding roller. During its main working process, it is connected to the conductive rubber mechanism through a high-voltage lead, contacts the membrane material through the conductive rubber, and forms a high-voltage test circuit with the grounding roller. Then, the ring-rewinding roller is used to unwind the material. The leakage current of this high-voltage test circuit changes with the moving membrane material. When there is a weakness (defect) somewhere in the membrane material, the leakage current of this high-voltage circuit will mutate, thereby giving feedback to the test host.

[0003] Among them, document CN215728579U discloses a thin film electrical weakness test device, which mainly solves the problem that the existing thin film electrical weakness tester is inconvenient to fix and move. However, during long-term use, it is found that the contact between the conductive rubber and the membrane material depends on the toughness of the conductive rubber itself, and the position of the conductive rubber is fixed. During long-term use and when the speed of the winding roller changes suddenly, the contact force will weaken, which may easily cause the risk of circuit continuity interruption. In order to optimize this solution, practitioners have designed an online detection mechanism for the electrical weakness of membrane materials. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1:

[0025] Combine Figure 1-4 The device is an online detection mechanism for electrical weakness of membrane materials, comprising a test host 1, with an electrical weakness detection mechanism 2 electrically connected to one side of the test host 1. The test host 1 is the primary interruption control device and can also receive test data from the electrical weakness detection mechanism 2 and integrate it into an intuitive image.

[0026] The electrical weak point detection mechanism 2 includes two sets of support plates 201 arranged relatively to each other, and a ring-releasing roller 202, a tension roller 203, a first guide roller 204, a grounding roller 205, a second guide roller 206 and a ring-collecting roller 207 are arranged between the two sets of support plates 201 in a rotating manner from top to bottom. A movable groove 2010 is provided on the side wall of the support plate 201 at the end of the tension roller 203, and a propulsion cylinder 2011 for controlling the travel locking of the tension roller 203 in the movable groove 2010 is provided on the outer wall of the support plate 201. This setting method drives the tension roller 203 to produce a certain displacement through the propulsion cylinder 2011, which can ensure the tension of the membrane material during the detection process. The first guide roller 204 is made of rubber material, and the end of the grounding roller 205 is connected to a ground wire to ensure The subsequent circuit structure of the grounding roller 205, the second guide roller 206 is made of metal material, and a driving motor 208 for driving the winding roller 207 to rotate is arranged on the outer wall of the support plate 201, and a conductive rubber mechanism 209 is arranged on one side of the grounding roller 205 to cooperate with it. The electrical weakness detection mechanism 2 as a whole drives the winding roller 207 to rotate through the driving motor 208 to pass the film material through the conductive rubber 20973 and the grounding roller 205 to form a continuously acting high-voltage test circuit. The leakage current of this high-voltage circuit changes with the moving film material. When there is a weakness (defect) somewhere in the film material, the leakage current of this high-voltage circuit will suddenly change. When this sudden leakage current is collected in the high-voltage circuit, the electrical weakness of the film is tested, and the test results are fed back to the test host 1.

[0027] Combine Figure 2 The conductive rubber mechanism 209 shown includes two sets of adjustment side plates 2091 fixedly arranged on the inner wall of the support plate 201, and both sets of adjustment side plates 2091 are provided with adjustment slots 2092. A support beam 2093 is slidably arranged between the two sets of adjustment slots 2092. The adjustment slots 2092 and the support beam 2093 are matched with each other by locking bolts 2094. This arrangement can change the position of the subsequent conductive rubber component 2097 by simply adjusting the locking bolts 2094, thereby adjusting the spacing between the conductive rubber 20973 and the grounding roller 205, and ensuring the most basic contact force given to the membrane material during subsequent action. An extension plate 2095 is provided at the bottom of the support beam 2093, and the extension plate 2095 is connected to the conductive rubber component 2097 by a torsion hinge 2096. The torsion hinge 2096 itself has a certain torsional force. This elastic torsional force will indirectly act on the conductive rubber 20973, further strengthening the good contact between the conductive rubber 20973 and the membrane material.

[0028] Combine Figure 3The conductive rubber assembly 2097 shown includes a rubber mounting base plate 20971, which has a mounting groove 20972, in which a conductive rubber 20973 is arranged. A high-voltage lead is connected to the end of the conductive rubber 20973. This arrangement can ensure that the membrane material is placed between the conductive rubber 20973 and the grounding roller 205 to form a high-voltage test circuit. A plum blossom bolt 20974 for fixing the conductive rubber 20973 is provided on the outer wall of the rubber mounting base plate 20971. The conductive rubber 20973 is fixed by the plum blossom bolt 20974, and the conductive rubber 20973 of the corresponding size can be quickly replaced according to the width of the membrane material to be tested.
