Transformer fireproof inspection detection device with global monitoring function

Abstract

The invention discloses a transformer fireproof inspection detection device with a global monitoring function. The device comprises a motor installed on the rear wall of a transformer, a rotating mechanism connected with the output end of the motor, a sensor assembly movably arranged on the rear wall of the transformer, a reciprocating mechanism connected with the rotating mechanism and used for driving the sensor assembly to transversely move in the transformer, and a driven mechanism connected with the reciprocating mechanism and used for driving the sensor assembly to longitudinally move on the reciprocating mechanism. According to the fireproof inspection detection device, the rotating mechanism does circular motion to drive the reciprocating mechanism to drive the sensor assembly to transversely move close to the rear wall in the transformer, and meanwhile, the reciprocating mechanism drives the driven mechanism to drive the sensor assembly to longitudinally move on the reciprocating mechanism, so that global detection of the internal space of the transformer is realized, and the detection range is widened; and compared with the existing fixed single-point detection, the fire hazard can be found in advance, and precious time is gained for fire hazard treatment.

Description

technical field [0001] The invention belongs to the technical field of electric power inspection, and in particular relates to a transformer fire prevention inspection and detection device for overall monitoring. Background technique [0002] As an important device in the power system, the transformer plays a vital role in the transmission-transformation-distribution of the power system. In recent years, with the leap-forward development of my country's power grid construction, transformers have gradually developed towards large capacity, high current and high voltage levels. Transformer fire accidents occasionally occur, and show an upward trend year by year. Once a fire accident occurs in a transformer, it will burn down equipment, causing economic and property losses, and seriously threatening the safe and stable operation of regional and even inter-regional power grids. At the same time, the transformer is generally filled with dozens or hundreds of tons of insulating oi...

Problems solved by technology

[0003] When there is a fire hazard in the substation, some indicators inside the transformer will change, such as the temperature and humidity inside the transformer, the smoke concentration inside the transformer, the concentration of hydrocarbons, and the image inside the transformer will all change, so it can be used in A sensor is placed inside the power transformer to detect the real-time data of the transformer as a basis for judging whether there is an abnormality or a fire hazard in the voltage transformer. However, in the existing technology, the installation position of the sensor is relatively fixed, and only a single point of local detection can be achieved. There are detection blind spots. It is impossible to detect hidden dangers in the first place, and it is impossible to achieve overall monitoring, which affects the timeliness and effectiveness of transformer monitoring
