Embodiment 1

[0027] This embodiment provides a method for preparing a zinc oxide surge arrester valve plate. After the raw material of zinc oxide is ground, granulated, formed, glue removed, high-resistance layer applied, sintered, and glazed, a zinc oxide magnet is formed, and then the cutting step is adopted. Correct the flat shape and shape of the end face of the zinc oxide magnet, spray aluminum on the end face of the zinc oxide magnet after cutting, and make the valve plate of the zinc oxide arrester.

[0028] In this embodiment, the cutting step includes:

[0029] Using a fixture to install and fasten the zinc oxide magnet on the cutting machine table;

[0030] Adjust the tension of the cutter blade, set the cutting depth, align the blade on the radial angle of the end face of the zinc oxide magnet, start cutting, and add circulating coolant at the same time; use the cut end face as the reference plane, stop and set Cutting width and cutting times, continuous automatic cutting after...

Embodiment 2

[0042] The only difference between this embodiment and Embodiment 1 is that this embodiment uses a split-type fixture to install and fasten the zinc oxide magnet on the cutting machine table;

[0043] Such as figure 2 As shown, the split-type tooling fixture 1 includes an adhesive material seat 11 and a fixed seat 12. The adhesive material seat 11 and the fixed seat 12 are split structures, and the vertical direction between the adhesive material seat and the fixed seat is adopted. The vertical phase indexing structure 13 is connected, or a horizontal phase indexing structure 14 is used to connect in the horizontal direction between the adhesive material seat and the fixed seat. Using this kind of fixture, during the cutting process, the zinc oxide magnet does not move, that is, the reference remains unchanged, and the vertical phase indexing structure 13 or the horizontal phase indexing mechanism 14 can be adjusted to cut the zinc oxide magnet from the second direction 3. ...

Embodiment 3

[0045] The difference between this embodiment and Embodiment 2 is that: in this embodiment, in addition to adopting a vertical phase indexing structure 13 to connect the vertical direction between the adhesive material seat 11 and the fixed seat 12, it is also possible to The horizontal direction between the adhesive material seat and the fixed seat is connected by a horizontal phase indexing structure 14, such as image 3 As shown, the vertical phase indexing structure and the horizontal phase indexing structure can be a combined indexing structure 15, so that the zinc oxide magnet can be cut from three-dimensional directions.

Abstract

The invention provides a preparation method of a zinc oxide lightning arrester valve plate. The preparation method comprises the following steps: performing grinding, granulating, forming, glue discharging, high-resistance layer coating, sintering and glazing procedures on a zinc oxide raw material to form a zinc oxide magnet, and the preparation method further comprises a cutting step for correcting the smoothness and the shape of the end face of the zinc oxide magnet in ahead of an aluminum spraying procedure. The cutting step comprises the sub-steps: mounting and fastening the zinc oxide magnet on a cutting machine worktable through a tool fixture; adjusting the tension of a cutting machine blade, setting the cutting depth, aligning the blade to the radial angle of the end face of the zinc oxide magnet, starting a cutting machine for cutting, and simultaneously spraying cooling liquid; shutting down to set the cutting width and cutting times, and continuously and automatically cutting after the setting operation, wherein the cut end face is used as a benchmark surface,; taking off the cut zinc oxide magnet and rim charge after the cutting operation. By adopting the preparation method provided by the invention, the end face of a zinc oxide lightning arrester electromagnet is smooth, and the technical effects of environment protection, high efficiency, low energy consumption and energy conservation are realized.

Description

technical field [0001] The invention relates to a preparation method of a zinc oxide arrester valve plate, in particular to a preparation method of a zinc oxide arrester valve plate which adopts a cutting processing method to modify the flat shape and shape of the zinc oxide magnet end face. Background technique [0002] Zinc oxide arresters have special nonlinear current-voltage characteristics. Once abnormal conditions occur during use, such as lightning strikes on the power line, strong electromagnetic field interference, frequent power switch actions, and power system failures, the voltage on the line will suddenly increase and exceed the conduction voltage of the arrester, and it will enter the conduction zone. At this time, the current (I) and the voltage (V) have a nonlinear relationship, which is generally called a nonlinearity parameter (Nonlinearity Parameter), and its value can reach tens or hundreds. At this time, the impedance of the arrester will drop sharply,...
