Integrated ultrasonic sensor

Abstract

The invention belongs to the technical field of sensors, and in particular relates to an integrated ultrasonic sensor. The integrated ultrasonic sensor is widely used and can perform partial discharge / failure breakdown detection on GIS (Geographic Information System) under various occasions. The invention comprises a contact ultrasonic sensor. A cover is connected to sensor housing. A cavity is provided in the sensor housing. A channel is provided from a bottom surface of the sensor housing to the inner cavity of the sensor housing. The sensor housing is further provided with a power switch, acharging indicator light, a charging base, and a signal transmitting antenna. There are four columns at the bottom of the cavity, and the heights of the two diagonal columns are the same, and an integrated circuit board I and an integrated circuit board II are respectively connected from low to high. A battery is arranged between the integrated circuit board II and an upper connection cover. Thelower part of the integrated circuit board II is sequentially connected with a spring and the contact ultrasonic sensor. The integrated ultrasonic sensor has the characteristics of small volume, simple structure, safe and portable, convenient operation and reasonable design and the like, can greatly improve work efficiency, and is suitable for popularization and application in the power equipmentindustry.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to an integrated ultrasonic sensor, which is widely used and can perform partial discharge / fault breakdown detection on GIS in various occasions. Background technique [0002] Gas insulated switchgear (GIS) has been widely used in power systems because of its high reliability, small footprint, simple maintenance, and long maintenance cycle. Some accidental factors in the design, manufacture, transportation and installation of GIS equipment will cause some local insulation defects, such as bubbles, cracks, suspended conductive particles and burrs, etc. These defects will cause the electric field strength in some areas inside the GIS equipment to be too high. Partial discharge occurs above the breakdown field strength of the insulating medium. If the discharge defects inside the equipment cannot be discovered and dealt with in time, equipment breakdown accidents will easi...

AI Technical Summary

Problems solved by technology

For many occasions, such as the high voltage level of GIS, the large size, the long distance between the sensor and the subsequent unit, the wiring is complicated, and the general cable is difficult to meet the requirements. In addition, the long length of the connecting cable will cause the signal The attenuation is relatively large during the transmission process, and the weight of the cable itself is relatively large, and it is easy to damage the interface between the sensor and the subsequent unit

The above situation will greatly reduce the efficiency of on-site ultrasonic testing of GIS equipment
