Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] figure 1 The hardware composition of the monitoring and evaluation system includes a monitoring host, which communicates with the corresponding sensors on the kinematic chain and each kinematic pair; the monitoring host is used to monitor the motion parameters of at least two kinematic pairs in the kinematic chain, and record them in real time; According to the transmission relationship between the kinematic pairs, the transmission performance of the kinematic chain is evaluated by comparing and judging the recorded information of the kinematic pairs. The communication means between the monitoring host and each sensor includes serial communication methods such as SPI and CAN bus.

[0021] According to the investigation and research on the current high-voltage switch, most of the transmission system of the high-voltage switch operating mechanism is a k...

Abstract

The invention relates to a method and a system for monitoring and evaluating the mechanical state of an intelligent high-voltage switching device. The system comprises a monitoring host which is communication connection with a corresponding sensor of each kinematic pair on a kinematic chain. The monitoring host is used for monitoring kinematic parameters of at least two kinematic pairs on the kinematic chain, and recording the kinematic parameters in real time. The transmission performance of the kinematic chain is evaluated according to the transmission relationship among the kinematic pairs by comparing and judging the recorded information of the kinematic pairs. According to the method for monitoring and evaluating the mechanical state of an intelligent high-voltage switching device of the invention, the kinematic performance of a whole kinematic chain is comprehensively analyzed and judged according to the transmission relationship among a plurality of kinematic pairs selected from the kinematic chain instead of being represented with data of a single kinematic pair.

Description

technical field [0001] The invention relates to a method and system for monitoring and evaluating the mechanical state of an intelligent high-voltage switchgear. Background technique [0002] A lot of research has been done on the subject of circuit breaker condition monitoring at home and abroad. Some scientific research institutes and manufacturers have carried out beneficial explorations on the monitoring of circuit breaker mechanical characteristics and fault diagnosis, and there are also some good applications. However, the methods adopted by these products are basically to install a travel sensor on the main transmission shaft of the operating mechanism, and to measure the movement amount of a certain part of the mechanism by the sensor to represent the overall motion characteristics of the operating mechanism instead. [0003] Although this method can explain the movement of the high-voltage switch operating mechanism to a certain extent, it cannot fully present the o...
