Converter transformer control cabinet air switch temperature on-line monitoring device

Abstract

The invention relates to a converter transformer control cabinet air switch temperature on-line monitoring device, which comprises a transmitting end and a receiving end in signal connection with thetransmitting end; the transmitting end comprises a sensor, a transmitting end control module and a transmitting end 433MHz module, the sensor is in signal connection with the transmitting end controlmodule, and the sensor transmits acquired temperature data to the transmitting end control module; the transmitting end control module is in signal connection with the transmitting end 433MHz module,data subjected to digital-to-analog conversion through the transmitting end control module are transmitted to the transmitting end 433MHz module, and the acquired temperature data are sent to the receiving end through the transmitting end 433MHz module. By adopting the technical scheme, the data security is improved; the monitoring cost is reduced; the workload of workers is reduced, and the safety risk is reduced, so that the work of the converter transformer can be safely and normally operated.

Description

Technical field [0001] The invention relates to the field of on-line monitoring of the operation state of a converter transformer, in particular to an on-line monitoring device for the temperature of an air switch of a converter transformer control cabinet. Background technique [0002] The converter station is the main component of the DC transmission project; the DC transmission project is usually used for long-distance, large-capacity power transmission. It is the main network of the power grid. As a converter station for AC / DC conversion sites, its importance is self-evident ; Most of the control equipment and main equipment of the converter station have realized automatic monitoring. Theoretically, the transportation and inspection personnel can monitor each device in the main control room. However, in actual operation, due to actual conditions such as cost, some equipment does not realize automatic monitoring, such as the core area of ​​the converter-the control cabinet ai...

AI Technical Summary

Problems solved by technology

However, in actual operation, due to the limitation of actual conditions such as cost, some equipment has not realized automatic monitoring. For example, the core area of ​​the converter - the air switch of the control cabinet, the control cabinet is small in size and dense in internal components, and the air switch is relatively easy It generates heat and is very sensitive, burying a huge hidden danger for the safe operation of the DC transmission system

[0003] Due to the lack of temperature monitoring means in the converter rheology control cabinet, the operator can only obtain the data of the air heating in the control cabinet through regular temperature measurement, and cannot continuously track and monitor the heating defects in time
