Description

Technical Field

[0001] This application relates to the field of resistor sheet technology, and in particular to a high-performance resistor sheet for a fixed external series gap surge arrester. Background Technology

[0002] Zinc oxide material is the core component of zinc oxide surge arresters, used to conduct lightning current into the ground, thereby suppressing the impact of lightning overvoltage on power users. Zinc oxide resistor elements, made from zinc oxide material, can change from a high-resistance state to a low-resistance state at the instant of lightning overvoltage, allowing high-power current to flow from the zinc oxide resistor element into the ground, thus protecting power equipment from damage by lightning current.

[0003] For example, Chinese patent application number CN201510930342.8 discloses a zinc oxide resistor sheet with high side flashover voltage, including a zinc oxide resistor sheet body, the outer side of the zinc oxide resistor sheet body is sequentially covered with a high resistance layer and a surface glaze layer, and the outer side of the zinc oxide resistor sheet is wavy, the extension direction of the wavy zinc oxide resistor sheet wave is consistent with the thickness direction of the zinc oxide resistor sheet.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] The core material of zinc oxide resistors is a valuable material that can be recycled. Normally, the body of a resistor is light green. However, for some used zinc oxide resistors, if the material of the resistor body has undergone a qualitative change, the resistor body will turn dark brown or gray. When recycling such resistors, it is necessary to break them down step by step to determine whether the corresponding resistor has recycling value. Identification during recycling is quite difficult. Utility Model Content

[0006] This application provides a high-performance resistor chip specifically for fixed external series gap surge arresters to improve the following technical problems:

[0007] When recycling these types of resistors, the resistors need to be broken down step by step to determine whether they have recycling value, making identification difficult during recycling.

[0008] This application provides a high-performance resistor element specifically for fixed external series gap surge arresters, employing the following technical solution:

[0009] A high-performance resistor sheet for a fixed external series gap surge arrester includes a resistor sheet blank and a high-resistance insulating layer surrounding the resistor sheet blank. The high-resistance insulating layer has an observation window, and a transparent glaze layer is provided on the outer periphery of the high-resistance insulating layer. The material of the transparent glaze layer fills the observation window. An anti-counterfeiting label is provided on the outer surface of the transparent glaze layer at a position corresponding to the observation window. The anti-counterfeiting label completely covers the observation window. After tearing off the anti-counterfeiting label, the color of the resistor sheet blank can be observed through the transparent glaze layer.

[0010] In one feasible technical solution of this application, the observation window is circular, and the diameter of the observation window is 0.4-0.6 times the thickness of the resistor sheet blank.

[0011] In one feasible technical solution of this application, the observation window is rectangular, and the width of the observation window is 0.4-0.6 times the thickness of the resistor sheet blank, and the length of the observation window is 0.8-1.2 times the thickness of the resistor sheet blank.

[0012] In one feasible technical solution of this application, the number of observation windows is one or two, and the two observation windows are symmetrically arranged on opposite sides of the resistor wafer blank.

[0013] In one feasible technical solution of this application, the anti-counterfeiting label includes a label body and an adhesive layer. The adhesive layer is bonded between the label body and the outer surface of the transparent glaze layer. After the anti-counterfeiting label is torn off, part of the label body and part of the transparent glaze layer remain on the outer surface of the transparent glaze layer.

[0014] In one feasible technical solution of this application, the outer surface of the transparent glaze layer is provided with a groove adapted to the shape of the anti-counterfeiting label.

[0015] In one feasible technical solution of this application, anti-slip ripples or anti-slip stripes are provided on the peripheral sidewall of the resistor blank.

[0016] In one feasible technical solution of this application, an aluminum-sprayed electrode layer is provided on both the upper and lower surfaces of the resistor blank, and the periphery of the aluminum-sprayed electrode layer covers the upper and lower end faces of the high-resistivity separator and the transparent glaze layer.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] During use, the anti-counterfeiting label can cover the observation window, which plays a certain role in preventing counterfeiting. It also helps users quickly obtain key information such as the manufacturer, model, and service life of the resistor. When recycling the resistor, the anti-counterfeiting label can be removed, and the color of the resistor body can be observed through the transparent glaze layer to see if it is light green. This allows for a quick determination of whether the resistor has recycling value, reducing the difficulty of identification during recycling. Attached Figure Description

[0035] Example 1

[0036] Embodiment 1 of this application discloses a high-performance resistor sheet specifically for fixed external series gap surge arresters. (Refer to...) Figure 1-3 A high-performance resistor sheet for a fixed external series gap surge arrester includes a resistor sheet blank 1 and a high-resistance insulating layer 2 wrapped around the periphery of the resistor sheet blank 1. An observation window 200 is provided on the high-resistance insulating layer 2. A transparent glaze layer 3 is provided on the outer periphery of the high-resistance insulating layer 2. The material of the transparent glaze layer 3 fills the observation window 200. An anti-counterfeiting label 4 is provided on the outer surface of the transparent glaze layer 3 at a position corresponding to the observation window 200. The anti-counterfeiting label 4 completely covers the observation window 200. After tearing off the anti-counterfeiting label 4, the color of the resistor sheet blank 1 can be observed through the transparent glaze layer 3. The observation window 200 is circular, and the diameter of the observation window 200 is 0.4-0.6 times the thickness of the resistor sheet blank 1. An aluminum-sprayed electrode layer 5 is provided on both the upper and lower surfaces of the resistor sheet blank 1. The periphery of the aluminum-sprayed electrode layer 5 covers the upper and lower end faces of the high-resistance insulating layer 2 and the transparent glaze layer 3.

[0037] In this embodiment, there are two observation windows 200, and the two observation windows 200 are symmetrically arranged on opposite sides of the resistor blank 1. In other embodiments, the number of observation windows 200 may be one.

[0038] In this embodiment, the anti-counterfeiting label 4 includes a label body 41 and an adhesive layer 42. The adhesive layer 42 is bonded between the label body 41 and the outer surface of the transparent glaze layer 3. After the anti-counterfeiting label 4 is torn off, part of the label body 41 and part of the transparent glaze layer 3 remain on the outer surface of the transparent glaze layer 3. The anti-counterfeiting label 4 designed above has a good anti-counterfeiting effect, preventing the anti-counterfeiting label 4 from being illegally reused and transferred.

[0039] To improve the installation firmness of the anti-counterfeiting label 4, the outer surface of the transparent glaze layer 3 is provided with a groove 31 that is adapted to the shape of the anti-counterfeiting label 4. In order to improve the connection firmness between the high resistance layer 2 and the resistor sheet blank 1, anti-slip ripples or anti-slip stripes are provided on the peripheral sidewall of the resistor sheet blank 1.

[0040] The beneficial technical effects of the high-performance resistor sheet for a fixed external series gap surge arrester according to Embodiment 1 of this application are roughly as follows:

[0041] During use, the anti-counterfeiting label 4 can cover the observation window 200, which plays a certain role in anti-counterfeiting and also helps users quickly obtain key information such as the manufacturer, model and service life of the resistor. When recycling the resistor, the anti-counterfeiting label 4 can be removed, and then the color of the resistor body 1 can be observed through the transparent glaze layer 3 to see if it is light green. This allows for a quick determination of whether the resistor has recycling value, reducing the difficulty of identification during recycling.

[0042] Example 2

[0043] Embodiment 2 of this application discloses a high-performance resistor sheet specifically for a fixed external series gap surge arrester. (Refer to...) Figure 1 and Figure 4 The difference from Example 1 is as follows:

[0044] The observation window 200 is rectangular, and the width of the observation window 200 is 0.4-0.6 times the thickness of the resistor sheet blank 1, and the length of the observation window 200 is 0.8-1.2 times the thickness of the resistor sheet blank 1.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
