Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
In order to realize the real-time monitoring of the operating environment and the operating state of the high-voltage transmission line, a sensor is arranged on the transmission line to achieve the purpose of detection. Various types of sensors can be arranged on the transmission line to acquire different types of data so as to comprehensively judge whether the transmission line is in a normal state. Optionally, in the embodiment of the present application, each sensor node is disposed at a central portion of a power transmission line conductor, and is powered by an independent sensor power supply system, each sensor node includes a plurality of sensors, and the parameters collected by the sensors generally include conductor temperature, inclination, current intensity, icing thickness, wind swing, ground distance, and the like.
Referring to fig. 1, the sensor power supply system includes: the device comprises a spacer, at least one energy taking device, a boosting energy taking device, an energy storage device and a management device. The energy taking device can be a high-voltage energy taking device or a solar energy taking device, and the energy storage device can be an energy storage battery.
Specifically, the high-voltage energy-taking device takes energy through a high-voltage coil, and obtains energy from a lead in the power transmission line through electromagnetic induction. Generally, the output of the high-voltage energy-taking device is alternating current which is processed by a power supply module to become direct current with constant voltage. The energy taking power of the high-voltage energy taking device is related to the number of turns of an energy taking coil, the sectional area of an energy taking magnetic ring and the current of the coil, and generally, the energy taking power is directly related to the current under the condition that the number of turns and the sectional area are determined. When the current is too small, the power of energy taking output is too small, and the voltage output after being processed by the management device still cannot reach the required voltage value; when the current is too large, the energy-taking output of the power-saving device is saturated, the current is increased continuously, and the output power is not increased any more. The solar energy acquisition device acquires electric energy through solar energy, the output of the solar energy acquisition device is direct-current voltage, and the solar energy acquisition device can be selectively configured in a sensor energy supply system and is not necessary.

The energy storage device is an energy storage battery, the battery is a main energy storage space, and when the energy taking power is high or the sensor does not work, the surplus power of the energy taking is used for charging the energy storage battery; when the energy is not enough and the sensor still needs to work, the energy storage device can provide electric energy for the sensor.
The management device integrates the working states of the energy taking device and the energy storage device, monitors the working states, finally transmits electric energy to the main control module and each sub-sensing module of the sensor through the energy taking device, and simultaneously is connected with the sensor through energy supply signal output to jointly control the action state of the sensor.
Optionally, the sensor energy supply system may further include a super capacitor, and the super capacitor may provide the sensor with the maximum power consumption in a short time due to the short-time peak power consumption in the sensor operation process, which may be greater than the maximum power that can be supplied by the energy obtaining module and the battery.
The spacer is mainly used for limiting the relative movement between sub-conductors and keeping the geometric shape of the split conductor under the normal operation condition, thereby satisfying the electrical performance, reducing the surface potential gradient and avoiding the electromagnetic force generated between the conductor wire bundles to cause mutual attraction and collision under the short circuit condition. The conductor spacer can connect many wires promptly at many intervals, gets to expect that the device connects different wires in order to carry out voltage and gets to expect, consequently, gets to expect that the device is connected with the conductor spacer.
