The Design And Implementation Of The System Of Temperature Monitoring Of High Voltage Switchgear

With the development of the national economy, the demand for electric powerindustries is increasingly high. Power plants, the temperature inside the substationhigh voltage switchgear contacts and increased with increasing current. If the highvoltage switchgear internal contacts junction temperature continued to increase,resulting in high voltage of switchgear internal contacts that occur switchgearoverheating incidents, and the resulting power outages and fires a large area.TMP102temperature sensor, MSP430microcontroller and CC2520chip ofwireless transmission form the high voltage switchgear of temperature node. In thework cycle in real time, the temperature sensor is dependent upon a wirelesstransceiver to send packets to the base station, after which the base station sent thedata to the back-end server Staff through RS485bus transfer. Through the PC,monitor, the temperature of high voltage switches cabinet can be inspected online.The power supply of substation electrical equipment is being completed throughthe substation high voltage switchgear, and the implementation group, if there is asubstation switchgear failure and it is not promptly notified, it is bound to affect theentire unit’s manufacturing operation and management. Therefore, the development ofsubstation of high voltage switchgear contacting temperature of monitoring system isnecessary.Researching and Developing temperature monitoring technology to improve theoverall safe operation of the power industry reliability of electrical equipment and electricalequipment maintenance levels, reduce labor intensity inspection personnel.
