Description
Technical field
The utility model is related to electric power repair technical fields, more particularly, to a kind of overtemperature warning ring.
Background technology
Cable run in actual operation, 110kV and the above tag tail pipe due to internal outer jacket sealing lead not
Jail or outer jacket ground wire are bolted loosening, cause contact resistance excessive, when big load, high current, easily
It causes local temperature excessively high and causes the breakdown of cable major insulation, line tripping.Major insulation failure often can not be self-healing, needs
It puts into a large amount of manpower and materials to be repaired, power grid affects greatly society.
It is necessary to carry out periodic maintenance monitoring to cable run terminal tail pipe, existing main method is regular to equipment for pole
Infrared measurement of temperature, to search heating accident.Operations staff periodically carries out thermometric detection by O&M strategy to cable terminal tail pipe, special
It is not line load hits new peak, night carries out thermometric, heavy workload, work importance is high.Infrared radiation thermometer is detected by environment
It is affected, cannot be carried out in the bad environments such as dust, smog, steam region；Essence is tested to bright or polishing metal surface
Degree is not high；The thermometric period is long, it cannot be guaranteed that finding defect in time；Part fever is changed with the variation of load, infrared measurement of temperature
Instrument detection can only measure state at that time, cannot record overtemperature state, infrared measurement of temperature is difficult to capture heating defect.Also have on the market
On-Line Monitor Device is developed, device is monitored cable tailpipe temperature, and on-Line Monitor Device power supply is unstable, data sensor mould
The easy failure of block, communication module reliability are low to cause single unit system reliability extremely low, and device overall cost is excessively high.
Therefore, be badly in need of developing it is a kind of not by weather, environment, measured object surface is smooth is influenced, and reliability it is high, at
Originally overtemperature alarming device low, that heating defect can be captured in time.
Utility model content
The utility model is that the infrared radiation thermometer described in the above-mentioned prior art is overcome to be easy by weather, environment, measured object table
The smooth influence in face and low, the of high cost defect of line monitoring device reliability, provide a kind of overtemperature warning ring.
In order to solve the above technical problems, the technical solution adopted in the utility model is：
A kind of overtemperature warning ring, including clip shape temperature-sensitive band and the fastening bolt for locking the clip shape temperature-sensitive band；
Temperature sensing glass ball is equipped on the outside of the clip shape temperature-sensitive band, the temperature sensing glass ball is wound with instruction band, the instruction band and institute
State clip shape temperature-sensitive band connection；
When temperature reaches the break temperature of the temperature sensing glass ball, the temperature sensing glass ball rupture, the instruction band is blown out.
The size of above-mentioned overtemperature warning ring can be customized according to the size of cable tail pipe or other annular heat-producing devices.
Overtemperature warning ring is looped around outside cable tail pipe, and is locked overtemperature warning ring by fastening bolt；Temperature-sensitive band with
The contact of cable tail pipe and sense temperature, when the temperature of cable tail pipe reaches the break temperature of temperature sensing glass ball, temperature sensing glass ball
Rupture, the instruction band being wrapped on temperature sensing glass ball are blown out.Staff only need to be by having seen whether that instruction band is blown out
Determine whether testee exceeds early warning temperature, to infer the febrile state of cable tail pipe.The break temperature of temperature sensing glass ball
It can be customized according to temperature alarm.
Above-mentioned overtemperature warning ring not by weather, environment, measured object surface is smooth is influenced, easy to install, adaptable, and
Reliability is high, at low cost, visual means can capture heating defect in time.
Preferably, temperature-sensitive block is equipped on the outside of the clip shape temperature-sensitive band, the temperature-sensitive block is equipped with for fixing the temperature-sensitive
The fixing groove of glass marble.Temperature sensing glass ball is fixed in temperature-sensitive block, temperature sensing glass ball passes through temperature-sensitive block and clip shape temperature-sensitive band
Perceive the temperature of measured object.
Preferably, multiple temperature sensing glass balls are equipped on the outside of the clip shape temperature-sensitive band.
Preferably, the different temperature sensing glass ball of multiple break temperatures, the temperature-sensitive are equipped on the outside of the clip shape temperature-sensitive band
The color of glass marble and corresponding instruction band is corresponding with break temperature.Corresponding different break temperature, setting temperature sensing glass ball and
The color of corresponding instruction band.Staff is according to the color of the colored ribbon blown out, you can judges temperature alarm.Temperature sensing glass ball with
The color of corresponding instruction band is identical, convenient for temperature sensing glass ball is corresponding with instruction band.
Preferably, the temperature-sensitive block is fixed at the both ends of the temperature sensing glass ball, is wound in the middle part of the temperature sensing glass ball
Indicate band.
Preferably, the instruction band is colored ribbon.
Compared with prior art, the utility model has the beneficial effects that：
Overtemperature warning ring provided by the utility model not by weather, environment, measured object surface is smooth is influenced, it is easy to install,
It is adaptable, and reliability is high, at low cost, visual means can capture heating defect in time.
