Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The present invention will be described in further detail with reference to fig. 1.
A device for monitoring the temperature of a high-voltage arrester is shown in figure 1. The method comprises the following steps: the system comprises a photocell, a large-capacity energy storage capacitor, a controller, an optical communication module, a temperature sensor (for example, but not limited to, a temperature sensor, which can be any kind of sensor), and the like.
The photovoltaic cell is a solar cell. Solar cells produce electrical energy as long as light is present. A solar cell is also called a "solar chip" or a "photovoltaic cell", and is a photoelectric semiconductor sheet that directly generates electricity by using sunlight. It can output voltage and generate current under the condition of loop as long as it is illuminated.
The monitoring device can be arranged at the high-voltage end or the low-voltage end of the lightning arrester (or at other parts of the lightning arrester), and is powered by a solar panel. Because the monitoring device has extremely low power consumption and adopts an intermittent communication method, the area of the required solar panel is very small, and the electric performance of the lightning arrester cannot be influenced.
The solar battery stores energy in a large-capacity capacitor under the condition of sunlight, the capacity of the capacitor is F-level generally, the voltage is lower than 10V, and the volume is small.
The energy stored in the capacitor is converted into the voltage at two ends of the capacitor through a DC/DC converter into the working voltage (usually 5V) required by a controller, and the controller monitors the temperature of the lightning arrester through a temperature sensor.
The controller communicates with the remote monitor in an intermittent, one-to-one, manner, by transmitting the monitored temperature signal to the remote monitor via insulated optical fibers. Because the controller adopts an intermittent question-answer mode, the power required by the controller is extremely small, the controller is in a dormant state normally, and relevant information is output when a signal needing to be transmitted is received. This minimizes the power consumption of the controller. The solar cell with smaller power can meet the requirement of long-term operation of the monitoring device.
The sensor type can be various, and if the sensor of the controller is replaced by other sensors, such as a wind speed and wind direction sensor, the monitoring device can also be used as a meteorological monitoring device.
To sum up, the utility model provides a monitoring devices for high-voltage arrester, include: the photoelectric detection device comprises a photoelectric cell, an energy storage capacitor, a DC/DC converter, a controller, an optical communication module and a sensor, wherein the photoelectric cell, the energy storage capacitor, the DC/DC converter, the controller and the optical communication module are sequentially and electrically connected; the photocell provides electric energy for the monitoring device and provides the electric energy for the energy storage capacitor; the DC/DC converter converts the voltage at two ends of the energy storage capacitor into the working voltage of the controller; the sensor is used for acquiring an operation signal of the high-voltage arrester and sending the operation signal to the controller; the controller receives the operation signal, generates operation data after processing, and transmits the operation data to the remote monitoring equipment through the optical communication module. The detection device does not change the electrical structure of the high-voltage arrester, can be installed at the high-voltage end or the low-voltage end of the high-voltage arrester, transmits the temperature of the high-voltage end of the arrester monitored by the monitoring device to a remote monitoring device by adopting an intermittent response optical communication method, reduces the power consumption of the monitoring device to the maximum extent, improves the reliability and the working continuity of the monitoring device, and can be widely applied to the outdoor installed high-voltage alternating current and direct current arrester for monitoring the temperature or other working states of the arrester.
