Description

Technical Field

[0001] This utility model belongs to the field of surge arrester valve body processing technology, specifically relating to a surge arrester valve body grinding fixture. Background Technology

[0002] A surge arrester valve body is an important device used to protect power systems or electrical equipment from overvoltage damage. The working principle of a zinc oxide surge arrester is based on the nonlinear volt-ampere characteristics of the zinc oxide resistor element. Under normal operating voltage, only a few hundred microamps of current flow through the zinc oxide resistor element. However, when a voltage surge occurs, the current flowing through the resistor element increases rapidly, diverting the large current to ground through the valve body, thereby limiting the amplitude of the overvoltage and releasing the overvoltage energy. When the operating voltage drops below the operating voltage, the zinc oxide returns to its high-voltage state, allowing the power system to operate normally.

[0003] In the existing technology, since the surge arrester valve body is a rubber molded product, the finished product will have burrs and rough edges. Due to the high-voltage operation characteristics of surge arresters, the inspection requirements for surge arrester valve bodies are: the surface must not have burrs, rough edges, or dents. Generally, operators use manual grinders to grind the rough edges of the valve body according to their own techniques and strength. The grinding accuracy is poor, the efficiency is low, the pass rate is low, the workload of quality inspectors is large, and the adaptability and practicality are poor. Utility Model Content
