Problems solved by technology

And after urban network transformation, XLPE cables are gradually replacing oil-paper cables, and XLPE cables are mostly shielded with copper tape, their cross-section is generally small, and the fault current allowed to pass is also small, so once there is a large fault current flow Outdated, there is a danger of being blown; if the fuse is blown within the set time of the relay protection or the relay protection does not operate normally, it will cause the fault to expand

Embodiment 2

[0048] An electric power information communication monitoring system, the control center is the information processing center of the system, which is connected with the communication terminal, the data acquisition module, the multimedia communication module, the data processing module and the user end, and can realize monitoring of other modules by sending instructions Information transmission, storage, collection, retrieval and other functions;

[0049] The communication terminal includes a base station, a substation, etc., and is connected with a data acquisition module and a multimedia communication module, and each communication terminal is equipped with a processor;

[0050] The wireless network access device is set on the convergence node of each communication terminal, the communication terminal sends information to the control center through the wireless network access device, and the control center updates the internal control system of the communication terminal throu...

Embodiment 3

[0056] The insulation state detection module in the data acquisition module adopts a coupling voltage sensor, which is arranged on the copper shielding layer inside the high-voltage cable; an oscilloscope is also provided, and the combination of the coupling voltage sensor, oscilloscope and communication terminal cable forms an equivalent circuit model.

[0057] Further, the specific steps of the insulation state detection are:

[0058] A1: using the coupling voltage sensor to collect the coupling voltage at the communication terminal cable;

[0059] B1: Calculate the phase angle α between the coupling voltage and the real voltage through the equivalent circuit model and related formulas;

[0060] C1: Calculate the real voltage value according to the coupling voltage and phase angle α.

[0061] Traditionally, it is not easy to measure the voltage phase of high-voltage equipment. Conducting live tests directly on the metal part of the running line requires strict live work rev...

Abstract

The invention discloses a monitoring system for electric power information communication, and relates to the field of electric power communication. The monitoring system comprises a regulation center,communication terminals, a wireless network access device, a data acquisition module, a multimedia communication module, a data processing module, and a user end. The data acquisition module, the multimedia communication module, and the data processing module are controlled by the regulation center. The data acquisition module acquires internal information and external environment information ofthe communication terminals by an external device, and transmits the acquired information to the data processing module. The information is transferred to a database after data integration. The multimedia communication module monitors the site condition of the communication terminals in real time in a multimedia form, and connects communication terminal nodes by the wireless network. Finally, thedata is transferred to the data processing module.

Description

technical field [0001] The invention relates to the field of electric power communication, in particular to an electric power information communication monitoring system. Background technique [0002] The power communication system came into being in order to ensure the safe and stable operation of the power system. The power communication optical cable is erected along with the power line, the optical cable is directly exposed to the outdoor environment, the operating environment is not ideal, and the life of the optical cable is directly affected by electrical corrosion and natural corrosion. The erection of power communication optical cables is widely distributed, and the power communication optical cables carry a variety of services, and the number of optical cables in the optical cable relay station is large. In order to ensure the operation quality of power communication optical cables, regular inspections and inspections of communication optical cables are required, ...
