Portable transformer substation noise imaging positioning detection device

Abstract

The invention discloses a portable transformer substation noise imaging positioning detection device which comprises an imaging displaying mechanism and a noise detection mechanism which are connected via a coaxial cable, the noise detection mechanism comprises a noise sensor of which a matrix is arranged on a quadratic surface structure and a signal pre-treatment circuit; the imaging display mechanism comprises a display, a processor and a data memory connected with the processor; the processor is provided with a sound intensity mapping processing module for driving and displaying a sound intensity mapping figure to quickly judge a noise resource. According to the position of equipment to be detected in a transformer substation, a cubic data module of a quadratic surface is established, a three-dimensional coordinate system is established on the basis of the cubic data module, and pre-treatment and pre-displaying of a relative noise signal are performed, spurious imaging information is used for noise imaging, and quick fault positioning is achieved by analyzing a color ring band. The portable transformer substation noise imaging positioning detection device effectively improves the efficiency of overhauling and maintaining the transformer substation, is simple, convenient and practical, and has very high promotion and application values.

Description

technical field [0001] The invention relates to the technical field of acoustic wave positioning equipment, in particular to a portable substation noise imaging positioning detection device. Background technique [0002] With the refinement of management, humanization of service, and standardization of data in electric power enterprises, the requirements for periodic testing and random testing of the operating status of electrical equipment are getting higher and higher, and the traditional listening and identification has been difficult to solve completely. On-site technical issues; research has found that any electrical equipment in operation, due to the action of alternating current, will produce various sounds and vibrations, these sounds and vibrations are unique to operating equipment, and are a feature that indicates the operating status of the equipment . For example, substations are mostly in an environment with multiple noises, most of which are power frequency so...

Problems solved by technology

However, the substation is also a place with a relatively special environment. When the substation is in operation, people are not allowed to approach the equipment. It is a dangerous area, and personnel are prohibited from approaching during work. It is very difficult to detect its fault defects

During the regular maintenance period, the technicians could not reproduce the fault phenomenon at high pressure. This problem has not been solved and a breakthrough has been made. It can only be inferred manually based on experience and large-scale replacement of equipment. However, the location of abnormal sounds can only be determined by the ear. hard to do

However, for a large amount of signal collection, data processing is cumbersome, and the accuracy rate is relatively low. At the same time, the requirements for the device are high, which is not easy to promote and use.
