Embodiment 1

[0037] The present invention is a fire prevention method for power cables in an active mode, such as figure 1 as shown, figure 1 It is a system flow chart of a preferred embodiment of the active fire prevention method for power cables provided by the present invention.

[0038] The present invention adopts an active fire prevention method for power cables, and its system includes:

[0039]A fireproof material module and a real-time sensing module; the output end of the real-time sensing module is unidirectionally connected to a filtering module, and the output end of the filtering module is unidirectionally connected to an acquisition module. The output end of the acquisition module is unidirectionally connected to a microprocessor, and the output shafts of the microprocessor are respectively interactively connected to a graphics imaging module, an alarm module and a wireless communication module, and the output terminals of the graphics imaging module are interactively conne...

Embodiment 2

[0048] The present invention also provides an embodiment, which is an active fire prevention method for power cables, such as figure 2 as shown, figure 2 for figure 1 Shown is a flow chart of the fire protection method for power cables in an active manner.

[0049] The present invention adopts an active mode fire prevention method for power cables, comprising the following steps:

[0050] A. Fireproof the cable skin and cable core through the first fireproof layer and the second fireproof layer to improve the fireproof performance of the cable itself;

[0051] B. Then use the gas sensor to sense the smell of the surrounding environment of the cable in real time to detect whether there is flammable and explosive gas in the ambient air. The smoke sensor senses the cable itself and the surrounding smoke in real time, and the temperature sensor senses the temperature value of the cable skin. When the cable itself or the surrounding environment is burning with an open flame, i...

Embodiment 3

[0059] Based on the same inventive concept, an embodiment of the present invention also provides a computer storage medium, on which a computer program is stored, and when the computer program is executed by a processor, the method described in Embodiment 1 or 2 is implemented. Procedures for fire prevention methods for power cables in active mode.

Abstract

The invention belongs to the technical field of power cables, and particularly relates to a power cable fireproof method adopting an active mode. According to the invention, through cooperation of the fireproof material module, flame-retardant and fireproof treatment can be carried out on the material of the cable, the combustion diffusion speed of fire on the surface of the cable is delayed, and the probability of fire occurrence of the cable is greatly reduced; with the cooperation of the real-time induction module, the odor type, the smoke concentration condition, the temperature value and the open fire combustion condition of the surrounding environment of the cable can be respectively sensed in real time, and then an alarm is quickly given to surrounding workers in a voice and light dual alarm mode through the microprocessor, the alarm module, the graphic imaging module and the wireless communication module. Meanwhile, the background receiving terminal can conveniently arrange a worker to quickly reach the fire position of the cable to take corresponding measures, and then summarize, compare and predict according to the collected information, so that the effect of nipping in the bud is achieved, and an active protection mode can be adopted for fireproof treatment on the cable.

Description

technical field [0001] The invention belongs to the technical field of power cables, and in particular relates to an active fire prevention method for power cables. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cables are cable products used to transmit and distribute high-power electric energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables. [0003] When users carry out power construction, they need to use power cables. However, due to the influence of surrounding environmental factors and the influence of the current and voltage passing through the cables, the power ca...
