Abstract

The utility model discloses a power bus temperature measuring system which consists of three major parts: a wireless temperature sensor, a data receiving terminal and a temperature measuring host, namely a workstation, wherein the wireless temperature sensor is responsible for collecting temperature data at a monitoring point and wirelessly sending the collected data out, the data receiving terminal is responsible for collecting the temperature data sent out by the wireless temperature sensor and uploading the collected data to the temperature measuring host through a network, and the temperature measuring host, namely the workstation is responsible for setting working parameters of the data receiving terminal, periodically reading the received temperature measurement data from the terminal, analyzing the data, and immediately giving an alarm when temperature beyond the alert level is found or temperature fluctuates abnormally. The power bus temperature measuring system achieves the purposes of convenient and simple control, wide control range, and self-testing of control signals.

Description

The power bus-bar temp measuring system
Technical field
The utility model relates to the technical field of industrial automation and control system, relates in particular to the technical field of power equipment temperature control.
Background technology
Along with modern power systems towards high voltage, big unit, jumbo developing rapidly, also increasingly high to the requirement of power supply reliability.The high-tension switch cabinet of generating plant, transformer station is important electrical equipment.In equipment long-time running process, positions such as the bus contact in the switch cubicle, high-voltage cable joint make adjacent insulation component capabilities deterioration because of aging or contact resistance is excessive generates heat, even puncture and cause the accident.According to statistics, electric system has an accident has quite a few relevant with heating problem in the reason.Therefore; The practical problems of solution is badly in need of in oneself the electrical equipment safe operation in becoming electric system of electrical equipment on-line temperature monitoring problem; Be to improve pressing for of electrical equipment reliability; To ensureing that the power system safety and stability operation has crucial meaning, the monitoring bus temperature of must adopting an effective measure.When temperature rise surpasses permissible value, must send alerting signal and in time remind the relevant personnel to take measures, avoid the generation of accident.
Summary of the invention
The purpose of the utility model provide a kind of intelligence, easily, range of control is wide, and power bus-bar temp measuring system easy to maintenance.
The utility model adopts following technical scheme for realizing above-mentioned purpose:
The utility model power bus-bar temp measuring system is characterized in that being made up of three parts:
Radio temperature sensor: be responsible for gathering the temperature data of monitoring point, and send out image data through wireless mode; Data receiving terminal: be responsible for collecting the temperature data that radio temperature sensor sends, and upload to the thermometric main frame to collected data through network mode; The thermometric main frame is a workstation: be responsible for that the data receiving terminal is carried out running parameter and set, from the terminal, read the temperature measurement data that is received periodically, and data are analyzed, temperature or the temperature generation unusual fluctuations of finding to surpass warning are instant alarming then.
Reasonable: 1 thermometric main frame is managed 250 data receiving terminals at most, and 1 data receiving terminal is managed 250 radio temperature sensors at most.
Reasonable: as to adopt the 433MHz wireless mode to be connected between data receiving terminal and the radio temperature sensor.
The utility model has realized that control is convenient, and simple, range of control is wide, the self-monitoring purpose of control signal.
The thermometric main frame has the Web service function, and the handle machine in LAN can be checked the situation of each point for measuring temperature in the temp measuring system through browser.
1 wireless temperature measuring system is generally only established 1 thermometric main frame, and 1 thermometric main frame is managed 250 data receiving terminals at most, and 1 data receiving terminal is managed 250 radio temperature sensors at most.That is to say that 1 wireless temperature measurement system can hold 62500 wireless sensers.
It is highly sensitive that state of temperature detects control module, and temperature is distinguishable at 0.5 degree, in 30ms, all accomplishes to sending to report to the police from temperature detection.
Adopt the 433MHz wireless mode to be connected between data receiving terminal and the radio temperature sensor, under unobstructed situation, wireless transmission distance is more than 100 meters.
The radio temperature sensor volume is little, is equivalent to matchbox size (comprising battery), and adopts energy-saving design, uses high-capacity battery, sustainable work 10 years.
Description of drawings
Fig. 1 is the overall applicability structural drawing of power bus-bar temp measuring system.
Embodiment
To combine accompanying drawing and specific embodiment that power bus-bar temp measuring system of the present invention is done to describe in detail further below.
As shown in Figure 1, the utility model power bus-bar temp measuring system comprises radio temperature sensor: be responsible for gathering the temperature data of monitoring point, and send out image data through wireless mode; Data receiving terminal: be called for short the terminal, be responsible for collecting the temperature data that radio temperature sensor sends, and upload to the thermometric main frame to collected data through network mode; Thermometric main frame (workstation): be responsible for that the data receiving terminal is carried out running parameter and set, from the terminal, read the temperature measurement data that is received periodically, and data are analyzed, temperature or the temperature generation unusual fluctuations of finding to surpass warning are instant alarming then.Temperature measurement data can be made the longer-term storage record in computing machine, supply query display at any time.The utility model has realized that control is convenient, and simple, range of control is wide, the self-monitoring purpose of control signal.
Reasonable: the thermometric main frame has the Web service function, and the handle machine in LAN can be checked the situation of each point for measuring temperature in the temp measuring system through browser.
Reasonable: 1 wireless temperature measuring system is generally only established 1 thermometric main frame, and 1 thermometric main frame is managed 250 data receiving terminals at most, and 1 data receiving terminal is managed 250 radio temperature sensors at most.That is to say that 1 wireless temperature measurement system can hold 62500 wireless sensers.
Reasonable: it is highly sensitive that state of temperature detects control module, and temperature is distinguishable at 0.5 degree, in 30ms, all accomplishes to sending to report to the police from temperature detection.
Reasonable: adopt the 433MHz wireless mode to be connected between data receiving terminal and the radio temperature sensor, under unobstructed situation, wireless transmission distance is more than 100 meters.
Reasonable: the radio temperature sensor volume is little, is equivalent to matchbox size (comprising battery), and adopts energy-saving design, uses high-capacity battery, sustainable work 10 years.
