Failure simulation device of sulfur hexafluoride circuit breaker

Abstract

The embodiment of the invention discloses a failure simulation device of a sulfur hexafluoride circuit breaker. The device comprises a shell, an arc control assembly and a control assembly, wherein the arc control assembly is arranged inside the shell, the control assembly is fixedly connected with the arc control assembly and is connected to the surface of the device after penetrating through the shell, and the shell and the arc control assembly are provided with a high-level glass window which is used for observing the internal structure of the failure simulation device. The switch-on and switch-off states of the circuit breaker can be simulated by operating the control assembly, the assemblies of the shell are connected through bolts, and adjustment or replacement of various components of the failure simulation device can be carried out so as to simulate various failure loading. Besides, signals of the interior of the failure simulation device can be collected in the failure simulation process through an electromagnetic wave sensor arranged on the failure simulation device, and reliable data is provided for failure diagnosis of the interior of the circuit breaker, thereby improving the safe operation of a power grid.

Description

technical field [0001] The invention relates to the field of circuit breaker state detection, in particular to a sulfur hexafluoride circuit breaker fault simulation device. Background technique [0002] In recent years, the power system has put forward higher and higher requirements for the reliability and economy of power supply. The safe operation of high-voltage power transmission and transformation equipment has become an important factor affecting the safe, stable and economical operation of the power system. There are a large number of circuit breakers in the power grid, which play a role in controlling and protecting the power grid. When a circuit breaker fails, it will directly cause a power grid accident, and even further expand the power grid accident, causing considerable economic and social losses. Effective detection of the working status of the circuit breaker, timely detection of early defects of the circuit breaker, and early processing of defective parts ca...

AI Technical Summary

Problems solved by technology

For the minor faults that have occurred during the arc extinguishing process of the circuit breaker, such as partial discharge, the contacts have a certain burning loss but are not damaged, etc., they cannot be found through routine preventive tests, and can only be detected by the circuit breaker during regular maintenance. Disassemble and overhaul each component to determine whether there is a slight fault inside the circuit breaker

[0004] It can be seen from the existing technology that the existing circuit breaker fault detection technology cannot detect the minor faults inside the circuit breaker in time, and there is no formed device that can provide reliable data for the research on the internal faults of the circuit breaker, which hinders the detection of circuit breaker internal faults. The research on internal faults is the development of treatment methods, making the internal faults of circuit breakers an important hidden danger affecting the safe and stable operation of power systems
