Technical field
The present invention relates to power circuit technical field, is warned more particularly, to a kind of overtemperature of power circuit splicing fitting Showing device.
Background technology
Power circuit is in actual motion, and splicing fitting junction is easily because bolt looseness, contact surface be dirty and cable Tail pipe sealing lead loosely, the reason such as copper Al electrochemical corrosion cause resistance to become big, when big load, high current, easily make It is too high into local temperature and trigger various failures.And failure caused by splicing fitting often can not be self-healing, it is necessary to put into Substantial amounts of manpower and materials are rushed to repair, and power network is affected greatly to society.
Therefore pole is necessary that power circuit splicing fitting is carried out regularly to safeguard monitoring, and existing main method is docking Continuous gold utensil carries out regularly infrared measurement of temperature, to search heating accident.Operations staff periodically carries out thermometric by O&M strategy to circuit Detection, particularly hit new peak in line load and carry out thermometric with night.But infrared measurement of temperature is protected from environmental larger, it is impossible to The bad environments such as dust, smog, steam region is carried out, and its measurement accuracy to smooth metal surface is not high.
The content of the invention
The present invention for solve prior art provide splicing fitting monitoring method existing for easily it is affected by environment, to the gold that continues Has the not high technological deficiency of measurement accuracy, there is provided a kind of overtemperature alarming device of power circuit splicing fitting.
To realize above goal of the invention, the technical scheme of use is:
A kind of overtemperature alarming device of power circuit splicing fitting, including lateral opening and the housing of bottom surface opening, activity Cover plate, motion bar, spring, fixed plate, portable plate, prompt band and temperature sensor;The fixed plate is fixed in housing, fixed plate with Housing is fixedly connected, and through hole is offered in the fixed plate, and the portable plate and removable cover are separately positioned on the upper of fixed plate Side and lower section, portable plate are arranged in housing, and removable cover covers to the bottom opening of housing, and removable cover passes through activity Bar through being connected with portable plate after the through hole in fixed plate, the both ends of spring, the both ends of temperature sensor respectively with portable plate, fixed plate Connection, prompt band are arranged on the motion bar between the top surface or fixed plate and removable cover of removable cover.
Under normal conditions, its internal spring is due to supporting role of the temperature sensor to portable plate and in drawing for overtemperature alarming device Stretch state.When using alarming device provided by the invention, temperature sensor is made to pass through the opening of housing side and splicing fitting Intimate surface contact, temperature sensor perceive the temperature of splicing fitting, when the temperature on splicing fitting surface is higher than early warning temperature, temperature-sensitive Body crack damage, now portable plate loses support, and is moved under the contraction of spring to the direction close to fixed plate, until In place, while portable plate can drive motion bar to move downward to spring contraction so that the body of rod of removable cover and piecemeal activity bar leads to The bottom opening for crossing housing exposes in housing, and prompt band is similarly exposed in housing, and operations staff need to only see whether prompting Band, which exposes, can determine that whether splicing fitting exceeds early warning temperature.
Compared with prior art, the beneficial effects of the invention are as follows:
Alarming device provided by the invention is perceived by temperature sensor to the temperature of splicing fitting, in the temperature of splicing fitting When degree is higher than early warning temperature, temperature sensor crack damage, now expose prompt band by the control of corresponding mechanical structure, you can to carry Show that the temperature of operations staff's splicing fitting exceeds early warning temperature.Alarming device provided by the invention has not affected by environment, survey The advantages of accuracy of measurement is high.
Brief description of the drawings
Fig. 1 is the structural representation of alarming device before temperature sensor rupture.
Fig. 2 is the structural representation of alarming device after temperature sensor rupture.
Fig. 3 is the setting schematic diagram of lifting ear.
Embodiment
Accompanying drawing being given for example only property explanation, it is impossible to be interpreted as the limitation to this patent;
Below in conjunction with drawings and examples, the present invention is further elaborated.
Embodiment 1
As shown in figure 1, alarming device provided by the invention includes lateral opening and housing 1, the removable cover of bottom surface opening 2nd, the first motion bar 3, the second motion bar 4, the first spring 5, second spring 6, fixed plate 7, portable plate 8, prompt band 9 and temperature sensor 10;The fixed plate 7 is fixed in housing 1, and fixed plate 7 is fixedly connected with housing 1, offers through hole in the fixed plate 7, institute State portable plate 8 and removable cover 2 is separately positioned on above and below fixed plate 7, portable plate 8 is arranged in housing 1, removable cover Plate 2 covers to the bottom opening of housing 1, and removable cover 2 passes through fixed plate 7 by the first motion bar 3, the second motion bar 4 On through hole after be connected with portable plate 8, the first spring 5, the both ends of second spring 6, temperature sensor 10 both ends respectively with portable plate 8th, fixed plate 7 connects, and prompt band 9 is arranged on the first activity between the top surface or fixed plate 7 and removable cover 2 of removable cover 2 On the motion bar 4 of bar 3 and/or second.
In specific implementation process, the both ends of the temperature sensor 10 pass through a fixedly connected part 11 and portable plate respectively 8th, fixed plate 7 connects, and set location of the fixedly connected part 11 in portable plate 8, fixed plate 7 is respectively positioned at portable plate 8, fixed plate 7 middle part, close to the lateral opening position of housing.First motion bar 3, the second motion bar 4 are separately positioned on where temperature sensor 10 The left and right sides of position, the first spring 5, second spring 6 extract the first motion bar 3, on the second motion bar 4 respectively.
In specific implementation process, the housing 1 is in hollow rectangular-shape, its bottom surface and lateral opening, selection Material can be plastics or metal.As shown in figure 3, it is provided with lifting ear 12 on the top surface of the housing 1.The temperature sensor 10 includes glass Glass shell and the liquid being contained in glass shell, the coefficient of expansion of the liquid is larger, can rise at a temperature of the early warning of setting Broken glass shell.The prompt band 9 is colored ribbon.
In such scheme, as shown in Figure 1, 2, under normal conditions, its internal spring is due to temperature sensor 10 for overtemperature alarming device Supporting role to portable plate 8 and be in extended state.When using alarming device provided by the invention, to make temperature sensor 10 logical The opening of the side of housing 1 and the intimate surface contact of splicing fitting are crossed, temperature sensor 10 perceives the temperature of splicing fitting, when the gold that continues The temperature on tool surface is when being higher than early warning temperature, the crack damage of temperature sensor 10, and now portable plate 8 loses support, and in the receipts of spring Moved under contracting effect to the direction close to fixed plate 7, until spring contraction is in place, while portable plate 8 can drive motion bar downward Motion so that the body of rod of removable cover 2 and piecemeal activity bar is exposed in housing 1 by the bottom opening of housing 1, prompt band 9 Equally expose in housing 1, operations staff need to only see whether that prompt band 9 is exposed and can determine that whether splicing fitting exceeds early warning Temperature.The concrete numerical value of early warning temperature can be configured by the liquid from the corresponding coefficient of expansion.
