A Fault Diagnosis Method for Catenary Disconnector

Abstract

The present invention disclosed a method of exposure to the exposure network fault diagnosis method. It uses fiber temperature sensors, fiber angle sensors, torque sensors, vibration sensors, current sensors, and acceleration sensors.Transfer the collected values to the simulation collector for processing, the simulation collector then transmits the processed information to the PC through the twisted twisting line through the RS485 communication method, and establish a barrier -based neural network -based quarantine switch failure in the PCDiagnostic models only need to separate the contact network of different faulty types corresponding to the faulty characteristics of the contact network. Establish a fault diagnostic model in the neural network, can identify different types of faults, and display the final diagnosis results on the upper machine, which is convenient for staff to intuitively intuitivelyCheck the type of faulty existence in the corresponding isolation switch.

Description

technical field [0001] The invention relates to the field of fault diagnosis, in particular to a method for fault diagnosis of a catenary isolating switch. Background technique [0002] The isolating switch is the most widely used electrical equipment in substations, which can perform no-load switching operations on the circuit system to form an isolation disconnection point. The action is mainly completed by the electrical control part and the mechanical transmission part. However, due to the long-term exposure of the equipment to the outdoor environment, the corrosion and wear of the mechanism are relatively large, which accounts for a large proportion of the daily maintenance work of the substation. Most of the isolating switchgear in substations is an outdoor open structure, and the working environment is harsh, which leads to problems such as poor lubrication, rust jamming, and serious wear of various parts of the mechanical transmission part. Incomplete head contact w...

Problems solved by technology

These commonly used isolating switch fault diagnosis methods are relatively scattered, and there is no unified planning together, which makes the diagnosis of isolating switch faults relatively simple, resulting in the staff being unable to accurately determine the type of isolating switch failure.
