Abstract
The utility model relates to an on-line temperature continuous monitoring system which is applicable to automatically monitoring the temperature of a power device. An infrared temperature sensor is arranged at an accessory of a heating part of a high-voltage device for measuring the electromagnetic radiation emitted by the heating device and converting temperature signals to electrical signals, anAD analog-to-digital converter is respectively connected with a single chip microcomputer and the infrared temperature sensor for constituting a temperature collection system, and the single chip microcomputer carries out data collection, processing and transmission on the signals, thereby realizing the real-time monitoring of the temperature of the high-voltage device. The on-line temperature continuous monitoring system can monitor the temperature of the heating devices in a real-time manner, such as a copper bar, a transformer and the like in a high voltage switchgear and other high-voltage devices, thereby realizing the on-line temperature continuous monitoring; and the whole system is further characterized by high measuring accuracy, high degree of intelligentization and the like, can find the hidden truth in advance, stifle electrical faults in the bud state and realize the purpose of preventing rather than curing.
Description
Technical field
The utility model relates to the online temperature continuous monitoring system that can monitor the power equipment temperature in the power technology field automatically.
Background technology
Along with developing rapidly of China's industry, the rapid increase of power load, local temperature rise often appears in high pressure equipment such as electric system middle-high voltage switch, disconnecting link when current-carrying is excessive too high, makes adjacent insulating element performance degradation, even puncture and cause the accident.According to statistics, electric system has an accident has quite a few and power equipment overheated relevant in the reason.Therefore, must the adopt an effective measure temperature spot of monitoring important high-tension apparatus part.
Often variable color indicating paster is attached on the important make and break contact in more current industries, utilizes the variation from deep to shallow of its color to judge the variation of contact temperature.This method is simply inexpensive, but accuracy is relatively poor, needs operator on duty's timing to patrol and examine, and working strength is big.Occurred a kind of portable infrared temperature measurer in recent years, contact measurement is not measured accurately, and price is more expensive, needs operator on duty's timing to patrol and examine equally, and performs record, so that analyze the temperature changing trend of each contact.More than two kinds of methods, all be to utilize manual method to carry out periodic monitor, measurement result and record data contain more human factor, and can not continuous monitoring.Therefore the real time temperature monitoring problem of visual plant and critical component in the electric system of solving has become the matter of great urgency of forceful electric power industry.
Summary of the invention
For solving the potential safety hazard that to carry out the real time temperature monitoring in the existing commercial production to equipment, the utility model provides a kind of online temperature continuous monitoring system, utilize microcomputer to come the temperature data of each contact is managed, stores, analyzes, and the contact that temperature anomaly changes is carried out emphasis monitor, keep in repair, to realize the purpose of online temperature continuous monitoring.
The technical scheme that its technical matters that solves the utility model adopts is: infrared temperature sensor is contained near the heat generating member of high-tension apparatus, send electromagnetic radiation to measure heater members, change temperature signal into electric signal, the AD analog to digital converter is connected with single-chip microcomputer, infrared temperature sensor respectively, constitute temperature acquisition system, single-chip microcomputer carries out data acquisition, processing, transmission to signal.Thereby realize real-time monitoring to the temperature of high-tension apparatus.
The utility model compared with prior art, can monitor the temperature of heater members such as copper bar, mutual inductor in high-tension switch cabinet and the some other high-tension apparatus in real time, realize online temperature continuous monitoring, total system also has characteristics such as measuring accuracy height, intelligent degree height, can find secret in advance, electric fault is nipped in the bud, accomplish to prevent trouble before it happens.
Description of drawings
Accompanying drawing is the utility model electrical block sketch.
Embodiment
As shown in drawings, the utility model is made of infrared temperature sensor 1, AD analog to digital converter 2 and single-chip microcomputer 3 three parts, AD analog to digital converter 2 is connected with infrared temperature sensor 1, single-chip microcomputer 3 respectively, and the model of AD analog to digital converter 2 is AD7705, and the model of single-chip microcomputer 3 is MSP430.Adopt infrared temperature sensor 1 to carry out untouchable measurement for the measurement of the local temperature of high-tension apparatus, heater members such as copper bar, mutual inductor send electromagnetic radiation in high-tension switch cabinet and the some other high-tension apparatus, and this electromagnetic radiation energy is measured by infrared temperature sensor 1; Utilize infrared temperature sensor 1 to change temperature signal into electric signal, be transported to AD analog to digital converter 2, utilize its A/D translation function and enter data into single-chip microcomputer 3 and carry out post-processed, thereby realize measurement temperature in conjunction with serial communication.Total system can realize the real-time detection to the temperature of high-tension apparatus owing to adopted single-chip microcomputer 3, high-speed AD analog to digital converter 2 and infrared temperature sensor 1.
