Detection platform for engineering machinery electrical equipment

Abstract

The invention discloses a detection platform for engineering machinery electrical equipment, and relates to the technical field of electrical equipment detection. The detection platform comprises a base, wherein two sides of the base are fixedly connected with a plurality of tire devices respectively; the upper surface of the base is rotatably connected with a rotary table; the upper surface of the rotary table are fixedly connected with an ultrasonic detection instrument and a pulse detection instrument respectively; the upper surface of the rotary table is fixedly connected with a fixed rod;the side wall of the top of the fixed rod is fixedly connected with a protruding shaft; the side wall, away from the fixed rod, of the protruding shaft is fixedly connected with a limiting block; anda plurality of first fixed holes are formed in the side wall of the top of the fixed rod. According to the detection platform, partial discharge detection can be carried out on the engineering machinery electrical equipment quantitatively and precisely through mutual cooperation of the ultrasonic detection instrument and the pulse detection instrument, detection errors are avoided to cause partial discharge and then accelerate aging of the electrical equipment, the detection platform can be applicable for different specifications and sizes of electrical equipment by setting a clamping plate with high degree of freedom, the generation of detection dead angles is avoided, and the detection process is more thorough.

Description

technical field [0001] The invention relates to the technical field of electrical equipment testing, in particular to a construction machinery electrical equipment testing platform. Background technique [0002] Conducting partial discharge test on electrical equipment is an important preventive test in the manufacture and operation of electrical equipment. If partial discharge exists for a long time, it will accelerate the aging of equipment, and even cause insulation damage under certain conditions, seriously affecting the normal operation of equipment. Partial discharge monitoring of electrical equipment is one of the most effective means to determine the location and cause of insulation faults. When partial discharge occurs in electrical equipment due to insulation faults, electric pulses, gas products, ultrasonic waves, electromagnetic radiation, light, local overheating, and energy loss will occur. Therefore, electric pulse detection methods, gas chromatography detect...
