Temperature monitor for distribution transformer

Abstract

The invention discloses a temperature monitor for a distribution transformer. The temperature monitor comprises a monitor base, wherein a groove is formed in the upper end of the monitor base; a sensor base is arranged in the groove; a temperature monitoring sensor probe for monitoring the temperature of the ambient environment of the distribution transformer is arranged on the sensor base; a small hole is formed in the sensor base; and a high-temperature wire is arranged at the lower end of the temperature monitoring sensor probe, one end of the high-temperature wire is electrically connected with the temperature monitoring sensor probe, and the other end of the high-temperature wire passes through the small hole and extends outwards. The temperature monitor is reasonable in structural design, simple in structure and reliable in operation, and the effects of preventing the distribution transformer from being damaged, improving the utilization rate of the distribution transformer and reducing running cost can be achieved.

Description

technical field [0001] The invention relates to the technical field of distribution transformers, in particular to a temperature monitor for distribution transformers. Background technique [0002] The demand for measuring the ambient temperature of distribution transformers is mainly an important basis parameter to reflect the temperature rise of transformers. Combined with the comprehensive analysis of transformer oil temperature and ambient temperature, the reference characteristics of operating load conditions and normal conditions of distribution transformers can be obtained. So far, distribution transformers The environmental temperature measurement around the power transformer has not been carried out so far. Therefore, it is necessary to develop a reliable distribution transformer temperature monitor to prevent damage to the distribution transformer, improve the utilization rate of the distribution transformer, and reduce operating costs. .
