Convenient-to-store connecting line for fault diagnosis

Abstract

The invention discloses a convenient-to-store connecting line for fault diagnosis. The connecting line comprises a diagnosis connecting line body, a probe socket plate is fixedly connected to the topend of the diagnosis connecting line body, a probe plug hole is formed in the surface of the probe socket plate, a probe plug is fixedly connected to the inner wall of the probe plug hole, the bottomend of the probe plug is fixedly connected with the top end of the diagnosis connecting line body, the bottom surface of the probe socket plate is fixedly connected with an anti-winding device, a diagnostic instrument plug is fixedly connected to the bottom end of the diagnostic connecting line body, the anti-winding device comprises plastic hose fixing rings, the bottom surfaces of the plastic hose fixing rings are fixedly connected with anti-pinch hoses, and the bottom surface of the anti-pinch hoses are fixedly connected with adjusting clamping plates. According to the convenient-to-store connecting line for fault diagnosis, the anti-pinch hoses, a fixed clamping plate, a clamping supporting rod, a fixed clamping rod and a fixed clamping groove are arranged so as to achieve the effect of conveniently storing connecting line for fault diagnosis.

Description

technical field [0001] The invention relates to the technical field of photovoltaic fault diagnosis and hearing equipment, in particular to a connecting wire for fault diagnosis and hearing that is convenient for storage. Background technique [0002] Photovoltaic power station fault detection is a photovoltaic operation management technology. There are many components of photovoltaic power stations, including photovoltaic arrays, DC combiner boxes, photovoltaic grid-connected inverters, AC power distribution cabinets, and step-up transformers. Among the many devices, photovoltaic arrays and photovoltaic grid-connected inverters are the core components of the entire photovoltaic power station. Among them, the cost of the photovoltaic array can account for 40%-50% of the construction cost of the entire photovoltaic power station, and when the photovoltaic array fails, the output power of the photovoltaic array will decrease, which will accelerate the damage of components and ...

AI Technical Summary

Problems solved by technology

There are three common types of faults in the operation of photovoltaic power plants, namely, inverter faults, AC transmission and distribution side faults, and DC transmission and distribution side faults. The fault diagnosis device judges the degree and location of the fault in the photovoltaic equipment. The fault stethoscope is an instrument that directly hears the sound emitted by the mechanical equipment when it is running in a physical way to judge the equipment fault and the hidden danger of the fault. Most of the existing fault stethoscopes are composed of sound Probes, connecting wires and earphones, and when the fault diagnosis stethoscope is not used for storage, the connecting wires are spring-shaped, and the connecting wires are easy to be entangled and knotted during storage, which is not convenient for the storage of the connecting wires
