Description
Technical field
The utility model relates to grid equipment field, in particular to a kind of on-line temperature monitoring instrument.
Background technique
With the economic development in China, society's electricity consumption amount also increasingly increases, and carries the high-voltage electricity of big electricity conveying task
The electrical load of gas equipment such as transformer, mutual inductor, disconnecting link, high-tension switch cabinet, cable etc. is also increasing sharply.And it is many in power grid
Tie point between more high-tension apparatuses and equipment is the most weak link of power Transmission.Because having in During Process of Long-term Operation
A little tie points can the aging or because fastening bolt the reasons such as loosens to increasing contact resistance due to oxidation corrosion.Lead to fever, become
Shape, the vicious circle generated heat again are until lead to a disaster.It is notified to count according to State Grid's safety accident, the etesian electric power in China
Accident, 40% is caused by high-tension apparatus overheats.State Power Corporation, which issues, " prevents power generation major accident 25
Important requirement " and " 18 great anti-accident measures of power grid of State Grid Corporation of China " in all made to high-tension apparatus and connection
The requirement of point temperature monitoring.
The temperature measurement of hyperbaric environment is always to perplex the big problem of electricity safety production, although recently as science and technology
Develop measurement means to make moderate progress, abandon traditional adhesive type thermometric wax disk(-sc) (manual patrol range estimation) mode, uses infrared
Thermometry, but there is also many realistic problems, using novel high-tech means solve this project have become one kind must
So.
Summary of the invention
The utility model aiming at the shortcomings in the prior art, provides a kind of generation that can effectively prevent fire incident, guarantees
The safe operation of high-tension apparatus, and the online temperature of most directly reliable data foundation is provided for operations staff and administrative decision layer
Detector.
The technical solution adopted in the utility model is as follows:
A kind of on-line temperature monitoring instrument, is made of temperature-measuring module, signal receiving module and monitoring modular, the temperature
Measurement module and the signal receiving module communication connection, the signal receiving module and the monitoring modular wireless telecommunications connect
It connects, the temperature-measuring module is multiple wireless type temperature sensors composition, and the signal receiving module is infrared emission reception
Module, the monitoring modular are made of minisize dc power supply, memory, PLC processor and display device, the micro DC
Source provides power supply for the memory, PLC processor and display device, and the PLC processor handles storage in the memory
Data and real-time display on said display means.
Preferentially, the inside of the wireless type temperature sensor is powered using high temperature high power lithium battery, built-in LTCC antenna,
Outside is encapsulated using high temperature and pressure heat-shrink tube and is reserved temperature surface.
Compared with the prior art, the beneficial effects of the utility model are as follows:
A kind of on-line temperature monitoring instrument of the utility model, by the way that multiple wireless type temperature sensors are installed to high-voltage switch gear
At Gui Nei busbar lap-joint, cable connector, the positions such as the disconnecting switch edge of a knife and handcart circuit breaker Mume flower contact, connect by signal
It receives module and temperature signal is sent to monitoring modular progress real-time monitoring, the utility model can effectively prevent the hair of fire incident
It is raw, guarantee the safe operation of high-tension apparatus, and provide most directly reliable data foundation for operations staff and administrative decision layer
Online temperature monitor.
Detailed description of the invention
Fig. 1 is that the utility model is electrically connected schematic diagram.
Specific embodiment
Referring to figure 1, a kind of on-line temperature monitoring instrument, by temperature-measuring module, signal receiving module and monitoring mould
Block is constituted, the temperature-measuring module and the signal receiving module communication connection, the signal receiving module and the monitoring
Module wireless telecommunications connection, the temperature-measuring module are multiple wireless type temperature sensors composition, the signal receiving module
For infrared emission receiving module, the monitoring modular is made of minisize dc power supply, memory, PLC processor and display device,
The minisize dc power supply provides power supply for the memory, PLC processor and display device, and the PLC processor handles institute
State the data stored in memory and on said display means real-time display.
Preferentially, the inside of the wireless type temperature sensor is powered using high temperature high power lithium battery, built-in LTCC antenna,
Outside is encapsulated using high temperature and pressure heat-shrink tube and is reserved temperature surface.
A kind of on-line temperature monitoring instrument of the utility model, by the way that wireless type temperature sensor is mounted on component to be monitored
On, multiple wireless type temperature sensors are such as fixed on by busbar lap-joint, cable in high-tension switch cabinet by silicon steel fixing belt and are connect
At the different locations such as head place, the disconnecting switch edge of a knife and handcart circuit breaker Mume flower contact, have to ensure temperature surface in fixation
With test face contact, after multiple wireless type temperature sensor fixations, then signal receiving module is fixed on high-voltage switch gear
Suitable position in cabinet, then multiple wireless type temperature sensors are connected to signal receiving module, the signal receiving module is
The temperature signal that multiple wireless type temperature sensors monitor is sent to prison by infrared emission receiving module, infrared emission receiving module
It surveys module and is stored in the memory of monitoring modular, after PLC processor handles memory and real-time display is being shown
On device, staff can check the temperature parameter at monitoring position in high-tension switch cabinet by display device, to judge height
In normal operation whether each component of the cabinet that compresses switch.The utility model can effectively prevent the generation of fire incident, guarantee that high pressure is set
Standby safe operation, and most directly reliable data foundation is provided for operations staff and administrative decision layer.
