Oil-filled cable plugging work well wireless monitoring system

Abstract

The invention relates to an oil-filled cable plugging work well wireless monitoring system which comprises a sensor module for collecting oil pressure data, water level data and a well cover state parameter, a wireless remote measuring and controlling terminal which is connected to the sensor module and is used for receiving and forwarding the data collected by the sensor module, a monitoring center server which is connected to a wireless remote measurement and control terminal and is used for receiving data forwarded by the wireless remote measurement and control terminal, analyzing and obtaining oil pressure information, water level information and a well cover state, and recording the oil pressure information, the water level information and the well cover state. Compared with the priorart, the current mature functions of data acquisition, GPRS data uploading and data analysis are used to establish a plugging well device monitoring platform, and the alarm state of the oil pressureof a oil pressure maintaining system of an oil-filled high-voltage cable is achieved and the real-time monitoring and alarming are carried out.

Description

technical field [0001] The invention relates to the field of electric power maintenance, in particular to a wireless monitoring system for oil-filled cable plugging wells. Background technique [0002] High-voltage oil-filled cables are mainly insulated with impregnated paper and low-viscosity cable oil. The oil-filled cables in Shanghai have been in operation for nearly 40 years and are reliable in operation. In order to compensate for the oil supply pressure of the long-distance oil-filled cable, a stopper well is built at an appropriate position in the middle of the oil-filled cable and equipped with oil supply pressure boxes, signal boxes, water pumps and other equipment to ensure stable oil pressure. [0003] The operation and management personnel need to know the sudden change of the oil pressure of the cable in time to prevent and avoid the cable failure caused by the oil leakage and pressure loss of the cable; Water will affect the operation safety of the equipment ...

AI Technical Summary

Problems solved by technology

[0003] The operation and management personnel need to know the sudden change of the oil pressure of the cable in time to prevent and avoid the cable failure caused by the oil leakage and pressure loss of the cable; Water will affect the operation safety of the equipment in the blocked well; the illegal opening of the well will often threaten the safe operation of the on-site cable equipment; in addition, the loss of voltage and power failure of the power supply of the well will cause the system to fail to monitor and alarm

In the Shanghai area, the blocked wells are mostly located on the driveways or sidewalks in the city center. The inspection procedures for each opening of the wells are more complicated. Personnel entering and exiting must take various safety measures such as on-site safety measures and work permits. Abnormal situations that occur cannot be detected in time

At present, there is no effective scientific monitoring method to achieve real-time monitoring of plug wells
