Online monitoring-evaluation device and method for vibration impact of mobile high-voltage transformation vehicle

Abstract

The invention relates to an online monitoring-evaluation device and method for vibration impact of a mobile high-voltage transformation vehicle, and belongs to transport quality evaluation technologies. The device comprises the mobile high-voltage transformation vehicle, a collection box mounted on the mobile high-voltage transformation vehicle and high-voltage transformation equipment arranged onthe mobile high-voltage transformation vehicle; the device comprises a foreground portion and a background portion; the foreground portion comprises multiple triaxial accelerometers, an online vibration impact monitor connected to the multiple triaxial accelerometers, and a display connected to the online vibration impact monitor; the online vibration impact monitor is connected to the backgroundportion via a built-in wireless communication module; and the triaxial accelerometers are installed on the high-voltage transformation equipment, and the online vibration impact monitor and the display are installed in the collection box. The device can realize online monitoring for the vibration impact acceleration of the mobile high-voltage transformation vehicle, reflect the vibration impact condition during transport of the mobile high-voltage transformation vehicle, and complete evaluation of the transport quality.

Description

technical field [0001] The invention belongs to the technical field of transportation quality evaluation, and in particular relates to an on-line monitoring and evaluation device and method for vibration shock of a vehicle-mounted mobile high-voltage substation car. Background technique [0002] The transportation monitoring and evaluation of high-voltage substation equipment is a link that manufacturers, transportation units and users attach great importance to. During transportation, if a high-voltage substation device experiences excessive mechanical vibration shock, it may cause a variety of visible and invisible damages. If the invisible damages are not detected and dealt with in time, the reliability of the device will be reduced. Reduced risk of accidents. [0003] At present, for the transportation of high-voltage substation devices, the impact recorder is often only installed on the transportation device to record the maximum acceleration of shock vibration during ...

AI Technical Summary

Problems solved by technology

During transportation, if a high-voltage substation device experiences excessive mechanical vibration shock, it may cause a variety of visible and invisible damages. If the invisible damages are not detected and dealt with in time, the reliability of the device will be reduced. reduce the risk of accidents

[0003] At present, for the transportation of high-voltage substation devices, the impact recorder is often only installed on the transportation device to record the maximum acceleration of shock vibration during the entire transportation process. The limit value is generally provided by the manufacturer or because there is no standard in China. Negotiated by both parties of the order contract, generally the limit value is 3g, and there is no other physical quantity as an evaluation reference value
