Description
Technical field
The utility model relates to a kind of temperature measuring equipment, relates in particular to a kind of instrument type intelligent radio temperature measuring equipment, be applicable to the indoor high-tension switch cabinet of 6～35kV high voltage bus and contact of breaker temperature monitoring and data recording with upload.
Background technology
High-tension switch cabinet is the visual plant in generating plant, the transformer station, plays a part to open and turn-off power supply, is used for realizing conveying and conversion electric load and from electric system, withdraws from faulty equipment and line segment, thereby guarantee safe operation of power system.High-tension switch cabinet is in the long-time running process, and positions such as contact point in the switch cubicle and bus (busbar) junction are no matter be the loosening or aging increase that all can cause contact resistance; Thereby cause that heating power is higher here, cause heating of contact, and temperature raises and can quicken the oxidation of surface of contact metal; Thereby further increase contact resistance, so just formed a vicious cycle, occur rapid rising of local temperature easily and cause contact fusing; Open circuit thereby cause, cause large-area power-cuts.In recent years, in power plant and transformer station a lot of switch cubicle overheat accidents having taken place, causes fire and large-area power outage, thereby influence the operate as normal of whole electric system, even bring about great losses.
Therefore real-time online detects the working temperature of contact, bus junction in the high-tension switch cabinet; Find in advance and get rid of hot stall hidden danger; Oneself becomes electrical equipment safe operation in the electric system and is badly in need of the practical problems that solves, and the safe and reliable operation of electric system is had very important significance.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency; A kind of instrument type intelligent radio temperature measuring equipment is provided; Pass through wireless data transmission; Solved the high pressure isolating problem of intelligent radio temperature measuring equipment of radio temperature sensor and the low pressure end of high-pressure side, the bus row junction of energy measurement 12 tunnel, the temperature of contact.
The purpose of the utility model is achieved in that a kind of instrument type intelligent radio temperature measuring equipment; It comprises main control chip; And the display module that links to each other with main control chip, memory module, communication module and radio receiving transmitting module, said temperature measuring equipment also is included as the power module of each module for power supply.
Said temperature measuring equipment also comprises the pre-alarm output module that links to each other with main control chip, and said pre-alarm output module comprises early warning output and the output two parts of reporting to the police.
Compared with prior art, the beneficial effect of the utility model is:
The utility model can be realized following advantage:
1, realizes the wireless signal reception of multichannel;
2, can store one month data;
3, real-time data presentation;
4, trend analysis automatically.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Fig. 2 is the systematic schematic diagram of the utility model.
Embodiment
Referring to Fig. 1, the utility model relates to a kind of instrument type intelligent radio temperature measuring equipment, mainly is made up of main control chip, display module, memory module, communication module, radio receiving transmitting module, pre-alarm output module and power module.
The data of all modules and the duty of the module of control except that power module are collected and handled to main control chip.Core for this temperature measuring equipment.
Display module is liquid crystal display, but data, device parameter and the canned data of the wireless temperature measurement sensor that display device receives, and have automatic screensaver functions.
But the communications parameter of memory module memory storage provides standard time clock like the calibration data of the temperature data of the MAC Address of sensor, sensor, device and for system.
Communication module is a RS-485 functional module, realizes the exchanges data of this temperature measuring equipment and other devices or system, can upload the sensing data and the state of all receptions in the temperature measuring equipment simultaneously.
Radio receiving transmitting module is realized the exchanges data of receiving trap and wireless temperature measurement sensor, and hands over main control chip to handle data.
The pre-alarm output module contains early warning output and the output two parts of reporting to the police, by its duty of main control chip control.
Power module is realized power source conversion, converts civil power (or high voltage direct current) reference power supply of system into, is each module for power supply.
Principle of work:
A kind of instrument type of the utility model intelligent radio temperature measuring equipment is directly installed on the static contact or electric connecting point in the contact box, directly contacts with actual heat generating spot, and the temperature of on-line measurement static contact and electric terminal is also sent data with the mode of less radio-frequency.Instrument type receiving trap receives the data of sending from intelligent radio temperature probe in the cabinet, shows the Current Temperatures and the preservation of each measured point respectively.When this temperature measuring equipment is higher than preset early warning or alarming value at dut temperature, output early warning signal or alerting signal, simultaneously with real-time temperature data or output state through the RS-485 bus, send the backstage industrial computer to the mode of Modbus agreement.
