A percussion acoustic detection device for insulator prtv coating quality

Abstract

The present invention relates to a knock sound measurement detection device of insulator PRTV coating quality. The device comprises a pickup box and a sound level meter, and a pickup pipe fixedly arranged at the pickup end of the sound level meter penetrates the pickup box from the right side wall of the pickup box and is in rotary joint with the pickup box via screw threads, wherein a pickup port is arranged on the pickup box, a pickup pot is fixedly arranged at the outer side of the pickup port, and an electromagnetic knocking device is fixedly arranged in the pickup box; the electromagnetic knocking device is composed of a solenoid valve, an electromagnetic push rod and a single-chip microcomputer controlling the solenoid valve, and the single-chip microcomputer controls the opening and closing of the solenoid valve via a pulse signal of a certain frequency, thereby realizing the situations that the electromagnetic push rod knocks the surface of an insulator, and the knock sound is acquired and displayed by the sound level meter. After being used for the actual power equipment maintenance, the knock sound measurement detection device of insulator PRTV coating quality of the present invention enables the labor intensity of the workers and the shutdown of the power transmission and transformation equipment to be reduced, and the safety of the power equipment maintenance work and the equipment power supply reliability to be improved.

Description

technical field [0001] The invention belongs to the technical field of grid insulator detection, in particular to a percussion acoustic detection device for PRTV coating quality of insulators. Background technique [0002] With the rapid and sustainable development of the national economy, the transmission network of various voltage levels continues to expand, and substations and overhead transmission lines are exposed to the air for a long time during operation. At present, the smog weather is becoming more and more serious, coupled with lightning, heavy rain, strong wind, ice and snow and other changeable weather, the operating environment of power grid equipment is very harsh, and the risk of power grid accidents caused by pollution flashover, fog flashover, rain flashover and equipment corrosion damage is increasing. Aggravating, these factors are the important reasons leading to large-scale power outages in my country's power grid. [0003] The insulator is an insulatin...

Problems solved by technology

[0004] At present, the most primitive manual inspection is still used in the PRTV coating quality inspection process, which is time-consuming and laborious, and there is no standard specification for the inspection technology, which may cause great hidden dangers to the safe and healthy operation of power equipment in the later stage

In addition, a power outage is required during the inspection, which seriously affects the reliability of the power supply. The primary substation equipment to be inspected is often located at a higher high-voltage wire connection tower, and the construction work is difficult and the risk factor is high.
