Porcelain bottle/porcelain sleeve acoustic vibration analysis instrument

Abstract

The invention relates to a porcelain bottle / porcelain sleeve acoustic vibration analysis instrument. The porcelain bottle / porcelain sleeve acoustic vibration analysis instrument has the main technical characteristics that a sound wave injector and a reflected wave receiver are mounted on one side of a shell side by side; a main board is arranged in the shell; the main board is connected with the sound wave injector and a sound wave receiver through signal wires; the main board comprises an MCU (Microgram Control Unit); a band-pass filter circuit, a power amplifier circuit and an isolating booster circuit are arranged between the signal output end of the MCU and the sound wave injector in turn; the band-pass filter circuit and a signal amplifier circuit are connected between the signal input end of the MCU and the reflected wave receiver in turn; the MCU is used for collecting, operating and treating the input signal; an MCU analysis result is displayed through a display screen. The porcelain bottle / porcelain sleeve acoustic vibration analysis instrument is used for performing system detection, analysis and system estimation on the long-distance bearing capability for the porcelain bottle / porcelain sleeve, stress status and running state and has the characteristics of high detection speed, long measuring distance, simplicity in operation, on-site instant resulting once measuring, capability of testing for outage and electrification, and the like.

Description

technical field [0001] The invention belongs to the technical field of power system detection and analysis, in particular to a porcelain bottle / porcelain sleeve acoustic vibration analyzer. Background technique [0002] In the power system, power equipment is installed on the top of the power porcelain vase and inside the porcelain sleeve. If it is damaged, it will malfunction, burn or fail together with the power equipment. Therefore, the health of the porcelain vase and porcelain sleeve will directly affect the safety and stability of the entire power grid. Because the porcelain bottle and porcelain sleeve are usually fixed on the metal frame, the height of the frame is between 2 meters and 10 meters from the ground, and its top or internal equipment carries tens of thousands of volts to millions of volts of high voltage. It is difficult for ordinary testing methods and testing instruments to detect It performs live system detection. In addition, due to the long-term powe...

Problems solved by technology

Because the porcelain bottle and porcelain sleeve are usually fixed on the metal frame, the height of the frame is between 2 meters and 10 meters from the ground, and its top or internal equipment carries tens of thousands of volts to millions of volts of high voltage. It is difficult for ordinary testing methods and testing instruments to detect It conducts live system detection

In addition, due to the long-term power supply operation of the power system, it is difficult to conduct systematic inspections on porcelain bottles and porcelain sleeves due to power outages. This is also the reason why there has been a lack of effective inspection methods and inspection equipment at home and abroad.
