Description

Technical Field

[0001] The present invention belongs to the technical field of high-voltage power grids, and in particular relates to an intelligent monitoring and early warning device and method for high-voltage power grids. Background Art

[0002] High-voltage power grid refers to an electric power network used for long-distance transmission of electric energy, usually with a voltage level of 110kV and above. The main function of the high-voltage power grid is to efficiently and reliably transmit the electric energy generated by power plants to various substations, and then distribute it to the low-voltage distribution network, and finally supply it to users. The stability and reliability of the high-voltage power grid are crucial to the normal operation of the entire power system. The intelligent monitoring and early warning device for high-voltage power grid is a device that integrates modern information technology and power system expertise. It is used to monitor the operating status of the power grid in real time, analyze potential failure risks, and issue early warnings in advance to ensure the safe and stable operation of the power grid. These devices collect multiple key parameters such as voltage, current, temperature, insulation performance, etc. through sensors, analyze and process them through data acquisition and transmission processing units, and then evaluate the power grid status through the central control system.

[0003] The existing intelligent monitoring and early warning device for high-voltage power grid judges the data of the high-voltage power grid through the data acquisition, transmission and processing unit and sends out early warning signals in time. The display screen is an indispensable part of the intelligent monitoring and early warning device for high-voltage power grid. It is responsible for the real-time monitoring video display and data graph of the high-voltage power grid. When the early warning device has no early warning, a single display screen can meet the monitoring of the high-voltage line. When the early warning device issues an early warning, its display screen cannot be expanded to multiple display screens so that personnel can intuitively and comprehensively observe all monitoring images and data graphs for early warning processing, which makes it difficult for monitoring personnel to quickly and comprehensively grasp the overall picture of the power grid operation. Since the information is scattered on different interfaces, it is necessary to switch frequently to view, which delays the recognition speed of emergency situations and affects the rapid decision-making and response of personnel. Summary of the invention

[0004] In view of this, the present invention aims at the deficiencies of the prior art and provides an intelligent monitoring and early warning device and method for a high-voltage power grid. When in the early warning state, the display screen can be expanded so that personnel can intuitively and comprehensively observe all monitoring images and data graphs for early warning, thereby improving the comprehensiveness and intuitiveness of monitoring. The centralized display of information reduces the time for operators to switch between different interfaces, which helps to identify abnormalities more quickly and take measures. In the non-warning state, the display screen can be used without expansion, saving energy.

A plurality of support feet are provided at the lower end of the support frame, and the plurality of support feet are respectively located at the four corners of the lower end of the support frame, and anti-slip pads are bonded to the lower ends of the plurality of support feet.

[0009] As a further improvement of the present invention, an observation window is arranged in the installation opening opened on the front side of the box plate.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] Firstly, by connecting the data processing unit on the mounting plate with the external high-voltage power grid data collection unit, and turning on the display screen data processing unit through the control panel control, the data processing unit integrates and processes the data transmitted by the high-voltage power grid collection unit and displays the data and monitoring images on the display screen for personnel to view. The box panel can also be opened through the handle to maintain the internal data processing unit, which is convenient for personnel to use.

[0012] Secondly, when the data processing unit detects that the output voltage data is abnormal, the data processing unit will control the warning light strip to start running, and flash a red light to warn and remind personnel to pay attention. At the same time, the data processing unit controls the motor to start running through the control panel, and the output shaft drives the screw rod to rotate and drives the rotating frame threadedly connected to it to move downward under the restriction of the slide rail, so that the rotating frame inside it rotates and expands, thereby driving the expansion screens on the expansion boards on both sides to move away from the inside of the frame board, completing the expansion of the expansion screen. At the same time, the data processing unit controls the expansion screens on both sides to start running through the control panel and cooperates with the display screen to display more comprehensive data and monitoring screens for personnel to view, thereby improving the comprehensiveness and intuitiveness of monitoring. Since the entire frame board is fixed to the door board by bolts, personnel can install the frame board to any suitable position by removing the bolts. The display screen in the warning state can be expanded so that personnel can intuitively and comprehensively observe all monitoring screens and data graphs for warning, thereby improving the comprehensiveness and intuitiveness of monitoring. The centralized display of information reduces the time for operators to switch between different interfaces, which helps to identify abnormalities faster and take measures. In the non-warning state, the display screen can be used without expansion, saving energy.

[0013] Thirdly, the cooling fan is turned on through the control panel, and the impeller rotates to pass the wind through the filter screen to filter the internal dust, and then blown into the inside of the box to dissipate the heat of the electrical components inside the box. Then the control panel is used to control the motor 2 to run forward and reverse, and the output shaft drives the gear 2 on the lower rotating column to rotate back and forth, and drives the remaining gear 1 to rotate back and forth through the toothed belt, and then drives the air guide plate on the rotating column to rotate back and forth. The wind blown by the fan can adjust the wind direction through the back and forth rotation of the air guide plate, so that the blown wind is more uniform, avoiding the problem of heat dissipation dead corners, and the air guide plate can be flexibly adjusted to ensure that the data processing unit is effectively cooled. The filter screen adopts a snap-on setting, which is convenient for personnel to remove it from the inside of the mounting shell for cleaning and replacement, thereby improving the overall heat dissipation efficiency and system reliability.

[0014] Fourthly, the box can be stably supported by the support frame and multiple supporting feet. At the same time, the anti-slip pad at the lower end can prevent the early warning device from moving during operation, making the operation of the monitoring early warning device more stable.

[0015] Fifth, through the observation window, personnel can understand the operation status of the data processing unit in real time without opening the box panel, thereby improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
