Abstract
The utility model discloses a kind of improved structure of contact arm wireless temperature measuring device, including contact arm, wiring board, thermometric coil；Longitudinally mounted groove is opened up in the middle part of described contact arm, annular groove is opened up in the one or both ends of contact arm；Described wiring board is fixedly mounted in the longitudinally mounted groove in the middle part of contact arm, and thermometric coil is movably arranged in the annular groove of contact arm outer end.Because wiring board of the present utility model is fixedly mounted in the longitudinally mounted groove in the middle part of contact arm, thermometric coil is movably arranged in the annular groove of contact arm outer end, temperature sensor on wiring board is placed on contact arm, by wireless host come reception signal during test, have the function that the temperature in pilot switch cabinet, there is the advantages of easy for installation, stable and reliable in work.
Description
Technical field
The field of circuit breakers of high-tension switch gear is the utility model is related to, more particularly to a kind of contact arm wireless temperature measuring device
Improved structure.
Background technology
Vacuum circuit breaker includes circuit breaker operation mechanism, pole or insulating cylinder, insulated tension pole, conductive contact arm, contact arm
Insulation sleeve and plum blossom moving contact, wherein conductive contact arm are essential accessories.Due to being to have to want to internal temperature in switch cubicle
Ask, so temperature measuring equipment is essential, existing temperature measuring equipment be by switch cubicle elsewhere, to monitor
Temperature, installation is inconvenient, and reception signal is unstable.
The content of the invention
The purpose of this utility model is to provide a kind of contact arm wireless temperature measuring device easy for installation, stable and reliable in work
Improved structure.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of improved structure of contact arm wireless temperature measuring device, including contact arm, wiring board, thermometric coil；
Longitudinally mounted groove is opened up in the middle part of described contact arm, annular groove is opened up in the one or both ends of contact arm；Described wiring board is consolidated
In the longitudinally mounted groove in the middle part of contact arm, thermometric coil is movably arranged in the annular groove of contact arm outer end for Dingan County.
The utility model also includes two insulating boots；Two described insulating boots are socketed in the both ends of contact arm respectively.
After such scheme, the longitudinally mounted groove that is fixedly mounted on due to wiring board of the present utility model in the middle part of contact arm
Interior, thermometric coil is movably arranged in the annular groove of contact arm outer end, and the temperature sensor on wiring board is placed on contact arm
On, have the function that the temperature in pilot switch cabinet by wireless host, there is easy for installation, work come reception signal during test
Make the advantages of reliable and stable.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model is a kind of improved structure of contact arm wireless temperature measuring device, including contact arm 1, wiring board
2nd, 3, two insulating boots 4 of thermometric coil.
The middle part of described contact arm 1 opens up longitudinally mounted groove 11, and annular groove 12 is opened up at the both ends of contact arm 1；Described
The wiring board 2 for being provided with temperature sensor is screwed in the longitudinally mounted groove 11 at the middle part of contact arm 1, thermometric coil
3 are movably arranged in the annular groove 12 of the outer end of contact arm 1.Two described insulating boots 4 are socketed in the both ends of contact arm 1 respectively,
Then heat-shrinkable T bush pyrocondensation is used, finally with heat-shrinkable T bush by the complete pyrocondensation in the middle part of contact arm 1.
Application method of the present utility model：
During thermometric, contact arm 1 is arranged on section breaker, after external wireless temperature measurement terminal is powered, when the electric current in switch cubicle
During >=11A, the temperature sensor of wiring board 2 will receive signal, be sent directly in terminal；Terminal can receive information simultaneously
Timely temperature is shown, critical-temperature can be set in terminal, when temperature exceedes critical value, alarm signal will be sent, is broken
All contact arms 1 are when being powered on the device of road, and when mutual temperature difference is excessive, alarm signal can be also sent in terminal.
It is described above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this
Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description, it all should still belong to this reality
In the range of being covered with new patent.
