Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insulating materials, and particularly relates to a sticky insulating material. Background Art
[0002] The function of a voltage transformer is to convert high voltage into a standard low voltage in proportion for use by measuring instruments, relay protection devices, etc. The high-voltage coil is a component of the voltage transformer. The high-voltage coil is usually wound with multiple turns of insulated wire and is directly connected to the measured high-voltage line. During operation, the high-voltage coil bears high voltage and generates magnetic flux in the iron core of the transformer through the principle of electromagnetic induction, and then induces a corresponding proportion of low voltage in the low-voltage coil. While bearing high voltage, the high-voltage coil requires good interlayer insulation to prevent interlayer short circuit and discharge phenomena.
[0003] At present, the insulating materials used often cannot be reused after one use, which not only causes waste of resources but also increases production costs. Moreover, during the use of these materials, residual glue often remains on the outer surface of the high-voltage coil. These residual glues not only affect the appearance of the product, but more seriously, they may cause a decrease in local insulation performance, thus affecting the insulation effect of the entire voltage transformer. Therefore, there is a problem that it is not convenient to reuse the insulating material. Content of the Utility Model

When the outer surface of the insulating layer 1 surrounds the outer surface of the high-voltage coil, the first adhesive layer 2 and the second adhesive layer 3 are torn off, and then the insulating layer 1 is folded so that the outer surfaces of the first adhesive layer 2 coincide with each other, and then the outer surface of the second adhesive layer 3 is attached to the outer surface of the third adhesive layer 6, thereby facilitating the winding of the insulating layer 1 around the outer surface of the high-voltage coil, facilitating the wrapping of the high-voltage coil, and further facilitating the repeated use of the insulating layer 1, preventing the occurrence of residual glue on the outer surface of the high-voltage coil. The buffer layer 4 and the protection mechanism 5 facilitate the protection of the high-voltage coil. The buffer layer 4 can prevent the high-voltage coil from being bruised.
