Description

A monitoring system for the tilting state of electric equipment and supports

technical field

The utility model relates to a monitoring system of electric power system equipment, in particular to a system for monitoring the inclination state of electric power equipment and supports.

Background technique

With the rapid development of large and medium-sized cities in my country and the requirements of urban planning, the scale of power transmission and transformation networks in power systems is also increasing, especially the high-voltage transmission and transformation networks of 110kV and above. High-voltage cables have been widely used in high-voltage power transmission and transformation networks due to their advantages such as less land occupation, convenient laying, personal safety guarantee, high power supply reliability, and less maintenance workload. Most of this type of high-voltage cables are installed by direct burial, tunnel, cable trench or bridge. According to the high-voltage cable laying regulations, steel structure brackets need to be installed on the wall at equal distances in cable tunnels or cable trenches. Accessories; at the cable terminal position, it is necessary to install a steel mechanism bracket on the ground to fix and support the cable to ensure reliable connection between the cable terminal and electrical equipment such as transformers and GIS.

At present, there is no special equipment for real-time monitoring of these steel structure cable supports on the market. Traditional methods are usually used for detection, that is, when inspecting the line, the supports at important positions are visually judged whether they meet the safety requirements. Understand the status of the bracket, and the inspection results rely more on the personal experience of the inspectors, and cannot be found in time when problems occur. The high-voltage cable body and terminal are fixed on the steel structure support. Changes due to various reasons (such as geological reasons) will cause the support to tilt and deform, resulting in relative displacement of the cable body, joints or terminals. In severe cases, the insulation structure will be damaged and insulation breakdown will occur. Power accidents cause power outages and lead to huge economic losses. Such accidents have occurred frequently.

Contents of the invention

The technical problem to be solved by the utility model is that there is no effective monitoring system capable of long-distance and real-time monitoring of the inclination state of electric equipment and supports.

In order to solve the above-mentioned technical problems, the utility model provides a monitoring system for the tilting state of electric equipment and supports, including a controller, a server, an inclination sensor, a real-time calendar chip, an address encoding chip, an address decoding chip, a memory and a client, and the control The controller is connected to the inclination sensor, the real-time calendar chip and the address coding chip respectively, the server is connected to the address decoding chip, the memory and the client respectively, the controller and the server are connected in a wired or wireless way, and the inclination sensor is installed horizontally and on the stand.

The inclination sensor is used to regularly detect the inclination angle signal of the power equipment and the support, and then the inclination angle signal is sent to the server for monitoring personnel to view in real time through the client, so as to realize remote real-time monitoring of the inclination state of the power equipment and support; The real-time calendar chip can allocate the collection time for the collected tilt angle, and send the collection time and tilt angle signal to the server, and the server will store the collection time and tilt angle signal in the memory correspondingly; the address coding chip can be used for each The position of each inclination sensor is address coded, and the address code, tilt angle signal and acquisition time are sent to the server together, and then the address code is decoded by the address decoding chip to obtain the position information of the inclination sensor.

As a further limiting solution of the present invention, a 3G network or GPRS wireless connection is used between the controller and the server. Using 3G network or GPRS wireless way to connect the server and the controller can reduce the wiring work during system installation, reduce the workload and reduce the installation cost of the system.

As a further limiting solution of the present invention, the controller and the server are connected by RS485 bus or optical fiber cable. Using RS485 bus or optical fiber to connect the server to the controller can ensure that the inclination angle signal can be effectively transmitted even when installed underground.

The beneficial effects of the utility model are: (1) the inclination angle sensor is used to regularly detect the inclination angle signal of the power equipment and the support, and then the inclination angle signal is sent to the server for monitoring personnel to check in real time through the client, thereby realizing the monitoring of the power equipment and the The inclination state of the support is monitored in real time at a long distance; (2) the use of a real-time calendar chip can allocate the acquisition time for the acquired inclination angle, and send the acquisition time and inclination angle signal to the server, and the server then sends the acquisition time and inclination angle The signal is correspondingly stored in the memory; (3) The address encoding chip can be used to encode the address of each inclination sensor, and send the address encoding, tilt angle signal and acquisition time to the server, and then the address is encoded by the address decoding chip Decode to obtain the location information of the inclination sensor.
