Problems solved by technology

As the cable length increases, the probability of fire accidents also increases accordingly. Once a cable fire occurs in a power plant, it will cause a large area of ​​cable burning, resulting in forced shutdown, unable to resume production in a short period of time, and causing major economic losses.

Embodiment Construction

[0017] The technical solutions of the present invention will be described in further detail below through specific implementation methods.

[0018] Such as figure 1 Shown, a kind of intelligent cable temperature on-line monitoring system comprises temperature sensor 1, first signal conditioner 21, first bus collector 31, GPRS data transmitter 4 and monitoring center; The input end of described temperature sensor 1 is connected to The cable body 5 at the cable joint or section monitoring, the output end of the temperature sensor 1 is connected to the first signal conditioner 21, and the temperature data is collected by the first bus after being processed by the first signal conditioner 21 Collected by the device 31, then uploaded to the monitoring center by the GPRS data transmitter 4. Due to the permanent and online nature of GPRS data transmission, it is possible to predict the fault trend of the cable head or the cable body 1, provide cable fault location and maintenance gu...

Abstract

The invention provides an intelligent cable temperature on-line monitoring system which comprises a temperature sensor, a first signal conditioner, a first bus collector, a smoke sensor, a second signal conditioner, a second bus collector, a GPRS data transmitter and a monitoring center. Being processed by the signal conditioners, the data collected by the temperature sensor and the smoke sensor is collected by the bus collector, and is then, uploaded to the monitoring center through the GPRS data transmitter. The intelligent cable temperature on-line monitoring system has the advantages of being economical and practical, convenient to use and ideal in running characteristic.

Description

technical field [0001] The invention relates to an online cable temperature monitoring system, in particular to an intelligent cable temperature online monitoring system for laying cables in a power plant. Background technique [0002] With the increase of the installed capacity of power plants, the level of automation is required to increase accordingly, and the amount of cables is increasing. For a 200MW unit, various cables are as long as 200-300Km. As the cable length increases, the probability of fire accidents also increases accordingly. Once a cable fire occurs in a power plant, it will cause a large area of ​​cable burns, resulting in forced shutdown, unable to resume production in a short time, and causing major economic losses. At present, most of the power plants under construction and in operation still use flammable cables, so the problem of cable fire prevention is particularly prominent. Cable overheating can be divided into two types: external thermal faults...
