A wireless sensor measurement system for high-voltage transmission network equipment

Abstract

The invention discloses a wireless sensing measurement system for a high-voltage power transmission network device. The system comprises a solar panel, a focusing lens, an input fiber bundle, an output fiber bundle, a sensing head, a photoelectric detector, a driving circuit and a wireless transmitting unit. A ground transmitting-receiving unit comprises a laser, a control circuit and a wireless receiving unit. The laser emits laser beams facing the solar panel and the focusing lens. The control circuit controls the wireless receiving unit to receive the measurement data transmitted by the wireless transmitting unit. A fiber sensor measures the parameters of the high-voltage power transmission network device, the sensing head is disposed inside the device, and is an optical device. External electrical devices are disposed in a shielded remote measuring chassis, which can avoid influences on the electric field parameters generated by a measured object. The fiber sensor is also unaffected by the electromagnetic interference of the measured object.

Description

technical field [0001] The invention belongs to the technical field of sensing and measurement, and relates to a measurement system for laser solar battery power supply and data wireless transmission. Background technique [0002] In the construction of high-voltage transmission network, it is necessary to monitor the parameters of high-voltage transmission equipment, such as the temperature of certain components, output voltage, and the liquid level of oil in the internal transformer, etc., to reflect whether the monitored object is normal. Since these devices are high-voltage devices, in order to prevent the sensor itself from affecting the electrical output of the device and high-power high-voltage devices from affecting the sensor measurement, active optical fiber sensors are often used to measure its parameters, such as transformer oil level sensors. And temperature sensors, etc. need to introduce laser light into the sensitive unit through optical fiber for light modul...

Problems solved by technology

Since these devices are located in the field at a height of more than ten meters to tens of meters, the ambient temperature range is large, and the power supply and data collection of the sensors are inconvenient to operate. It is urgent to carry out new measurement technology research and measurement system development to solve its practical application problems.
