Description
Technical field
The present invention relates to power equipment thermometric, particularly relate to one kind and be mainly used in power system when high voltage appearance, big
The breaker passive wireless temperature measuring device and thermometric monitoring system of current work state.
Background technology
The high-tension switch cabinet commonly used in power system is chronically at the working condition of high voltage, high current, switch cubicle
Breaker generally using moving cart pattern fix breaker.Under service work or power-off condition is carried out, operations staff
Circuit breaker trolley is pulled out into switch cubicle.Due to such structure, breaker Jing is often in Mechanical Contact, the state of friction.When
Between the contact of breaker long afterwards cause contact or joint temperature because the change of aging or mechanical location causes contact resistance to increase
Raise, if without process in time, it will produce vicious circle, ultimately result in and burn high-tension switch cabinet, or even directly affect electricity
Force system normal power supply and cause huge economic loss.Therefore, reality is carried out to the temperature of contact of breaker in high-tension switch cabinet
When monitor, for the safe operation for ensureing high-tension switch cabinet, or even the safety in production of electrical network is all had a very important role.
Under high voltage, high current environment, realize that the on-line monitoring of temperature needs to solve high_voltage isolation and anti-strong electromagnetic is dry
The difficult problem disturbed.The contact temperature on-line monitoring technique of existing high-tension switch cabinet inner breaker mainly has following several：
(1) apply one layer of temperature on the surface of bus joint and breaker contact point and become material, the face for varying with temperature and changing coating
Color, by observing its color change come substantially temperature scope.This method degree of accuracy is low, readable difference, it is impossible to which it is fixed to carry out
Amount and in real time measurement, method is original and employee is had high demands.
(2) using thermal infrared imager or point Wen Yi, operating personnel's timing hand-held instrument is directed at bus joint and high-voltage switch gear
Contact measures.Temperature value error of this method between 0～200 DEG C is little, the degree of accuracy is high, but cannot accomplish survey in real time
Amount, transient temperature when being only capable of obtaining detection, and price is high, optics uses inconvenience in high pressure occasion.
(3) by the way of optical fiber, this method is implemented and is divided into two kinds, and one kind is passed using optical fiber grating temperature
Sensor, another kind is, merely with Optical Fiber Transmission temperature signal, both to make use of that optical fiber is high pressure resistant, anticorrosive, electromagnetism interference
The advantages of, the greatest drawback of the technology is that tested high-voltage charged body needs to be connected by optical fiber with measuring apparatus, therefore can not be solved
The certainly problem of pollution flashover, strictly speaking the security of the technology be worth discussion, while increasing the difficulty of site operation.
(4) by the way of wireless temperature measurement, this mode is to make temperature sensor and data set using wireless communication technology
Wireless Data Transmission is realized between middle display, any physical arrangement is not made to switch cubicle and is changed, also do not carry out construction wiring,
High_voltage isolation is solved the problems, such as well, while solving making for temperature acquisition terminal using ultralow Consumption and shield technology
With life-span and the problem of anti-strong electromagnetic.
The breaker of power system, particularly main transformer, bus-tie circuit breaker are difficult to have a power failure, the normal whole station of transformer station
The cycle of interruption maintenance is in 4-6.It requires that all of temperature sensing meanses should be installed under full transformer station not power-off condition, examined
Survey.
Brush temperature change material and be not suitable for breaker.Breaker is all reinforced and encapsulated using closing metal dolly, in band
It is cannot to use to be observed visually color change situation in the case of electricity；
Because switch cabinet of converting station is closed by metal cabinet, the watch window of switch cubicle adopts common glass, infrared ray
This material cannot be passed through.Thermal imaging system is caused to measure the temperature of equipment in switch cubicle, even if being mounted with infrared viewing window
Mouthful, also due to blocking for the part such as the metal shell of circuit breaker trolley, insulating part causes thermal imaging system to obtain contact of breaker
Visual angle；
Optical fiber temperature-measurement needs to arrange optical fiber and optical fiber temperature acquisition terminal, such need of work switch cabinet bus inside cabinet
Installment work is carried out under power-off condition.So for deployment, installment work are made troubles.Additionally, due to the physics of Fibre Optical Sensor
, there is temperature drift phenomenon in characteristic reason, needs carry out a temperature checking job for 3 years.Such verifying work is also required to power failure and tears open
Unload sensor.
Traditional wireless temperature measuring device, due to the stationary contact rostral installed in busbar side or breaker, it is also desirable to which whole station is stopped
Electricity is installed.In addition the wireless temperature measuring device of major part producer is powered using battery, thus in the case of a high temperature the life-span there was only 2 to 3
Year.
