Application of wireless temperature measuring products of Acrel in substation

1.Project Overview

With the rapid development of the scale of the power industry in various countries,, the demand for electricity continues to rise.And power transformers continue to develop in the direction of large capacity and high voltage. As an important power equipment in the power system, the safety and reliability of the operation of the transformer will have a direct impact on the power supply quality of the power grid. Power transformer faults mainly include thermal faults and electrical faults, of which overheating faults account for about 63% of the total number of faults. Therefore, the implementation of online monitoring of transformer temperature is of great significance to ensure the safe and stable operation of the transformer.

2.Introduction

ATE series wireless temperature measuring sensor has been developed in compliance with Specification for Wireless Temperature Measuring equipment, NB/T 42086-2016. It is suitable for 3-35kV indoor switchgears, including built-in switchgears, handcart switchgears, fixed switchgears and loop-net switchgears. It is also suitable for 0.4kV low-voltage switchgears such as fixed switchgears and drawer switchgears. The wireless temperature sensors can be installed at any heating point in switchgears, the device utilizes the wireless data transmission technology for real-time transmission of monitored temperature data. In addition, it can be transmitted to display device or remote intelligent monitoring system.
