Embodiment Construction

[0014] As shown in the drawings, the technical solution adopted by the present invention is: a hydraulic operating mechanism buffer oil pressure detection and analysis system, including a pressure sensor 1, a travel sensor 2, a control and data acquisition system 3, a data receiving and analysis system 4, etc. . Among them, the pressure sensor 1 is an ultra-high frequency and ultra-high pressure pressure sensor. A signal amplification circuit board is installed in the wiring seat of the pressure sensor 1, which can convert the transient oil pressure of the ultra-high oil pressure into a current signal. The travel sensor 2 adopts a linear or Rotary scribing rheostat sensor, each sensor signal is connected to the acquisition system through a shielded wire. The control and data acquisition system 3 includes the operation control part of the hydraulic mechanism and the analog signal acquisition conversion and storage part. The system is assembled in a box module, which can collec...

Abstract

The invention, which belongs to the technical field of testing of transmission and transformation equipment, in particular relates to a detection and analysis system of a buffer oil pressure of a hydraulic operating mechanism. The detection and analysis system is composed of a stroke sensor, a current sensor, a control and data acquisition system, a data receiving and analysis system and the like.The pressure sensor is an ultra-high-frequency ultra-high-pressure pressure sensor. The control and data acquisition system consists of an operation control part of a hydraulic mechanism and an analog signal acquisition, conversion and storage part. The data receiving and analysis system is able to receive a digital signal converted by the acquisition system and analyzes and processes the received signal. According to the invention, while the opening ad closing operations of the hydraulic operating mechanism are controlled, the mechanical characteristic and transient buffer oil pressure of the hydraulic operating mechanism are detected and analyzed. The detection and analysis system has advantages of great simpleness, high integration, low signal transmission distortion, great conveniencein operation, and high portability and is capable of detecting and analyzing the corresponding relationship between the buffer oil pressure and mechanical characteristic data simultaneously.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation equipment testing. [0002] Specifically, it is a hydraulic operating mechanism buffer oil pressure detection and analysis system. Background technique [0003] In the development of the hydraulic operating mechanism and the matching of the characteristics of the hydraulic operating mechanism and the high-voltage circuit breaker, it is necessary to detect and analyze the buffer oil pressure of the hydraulic operating mechanism. By controlling the buffer oil pressure, the matching performance of the circuit breaker is excellent, thus ensuring The reliability of the hydraulic operating mechanism and the movement reliability of the high-voltage circuit breaker. Due to the ultra-high pressure and transient characteristics of the buffer oil pressure, the highest buffer pressure may reach nearly 200Mpa, and the duration is only more than ten milliseconds, so it is difficul...
