Transformer substation oil shortage equipment monitoring system based on wireless intelligent sensor

Abstract

The invention discloses a transformer substation oil shortage equipment monitoring system based on a wireless intelligent sensor. The system comprises front-end acquisition terminals which are used for acquiring temperature and pressure detection data of oil shortage equipment of a transformer substation and transmitting the data through a wireless module; repeaters which are in wireless communication with the front-end acquisition terminals and are used for receiving the data acquired by the plurality of front-end acquisition terminals and remotely transmitting the data; and a wireless communication gateway which is used for receiving the information transmitted by the repeaters and uniformly transmitting the information to a far-end monitoring center through a power grid communication module. The front-end acquisition terminals and the repeaters are both powered by solar cell panels and standby batteries together, so that the service time of the front-end acquisition terminals and the repeaters in the system is prolonged. The front-end acquisition terminals transmit acquired information such as temperature and pressure to the repeaters through the wireless module, and the information is uploaded to the wireless communication gateway through the repeaters, encrypted and finally transmitted to the far-end monitoring center through network signals. The system components are simple, the installation cost is low, and safe and reliable transmission of the monitoring data can be realized.

Description

technical field [0001] The invention relates to a wireless intelligent sensor online monitoring system, in particular to a wireless intelligent sensor-based substation oil-less equipment monitoring system. Background technique [0002] Oil temperature and oil pressure wireless smart sensors are widely used in substations. Switch cabinets and circuit breakers are high-voltage electrical appliances widely used in power systems. The reliable operation of these sensors has become one of the biggest concerns of the power supply and utilization departments. [0003] Existing equipment used to monitor oil shortage in substations is realized by monitoring temperature and pressure; the temperature information and pressure information collected by sensors in the prior art cannot be transmitted to the remote end, so people must read on site; for mechanical density The on-site reading (meter reading) of the relay is also slightly complicated, and sometimes the monitoring data cannot be...

Problems solved by technology

[0003] Existing equipment used to monitor oil shortage in substations is realized by monitoring temperature and pressure; the temperature information and pressure information collected by sensors in the prior art cannot be transmitted to the remote end, so people must read on site; for mechanical density The on-site reading (meter reading) of the relay is also slightly complicated, and sometimes the monitoring data cannot be accurately read due to the limitation of the sensor installation location;

[0004] Existing monitoring sensors realize data transmission by adding wireless modules, but only for short-distance data transmission on site, which requires monitoring personnel to receive data with handheld terminals, and cannot perform long-distance data and transmission, and field data Upload to the remote monitoring center, the operation steps are cumbersome, the installation organization is too complicated, the installation and maintenance results are too high, and the promotion in many places has encountered obstacles
