Abstract
The utility model relates to extra-high voltage direct-current field, discloses a kind of extra-high voltage direct-current measurement mechanism with heat abstractor.The utility model designs a series of heat radiator in ring flange end, extra-high voltage direct-current voltage measuring apparatus top, and this heat abstractor absorbs sends out heat thermogenetic from insulating cylinder inner conductor, is then outwards transmitted by ring flange by heat.It is simple that this structure has structure, and the feature of perfect heat-dissipating, has good heat radiator effect for the heating in the steady-state operation of extra-high voltage direct-current voltage measuring apparatus.
Description
Technical field
The utility model belongs to extra-high voltage direct-current field, relates to a kind of extra-high voltage direct-current measurement mechanism with heat abstractor.
Background technology
China's high pressure, extra-high voltage direct-current power transmission and transformation system require that voltage measurement accuracy is 0.2 grade, and general DC voltage measuring device design mainly concentrates on resistance, the choosing and stability of capacitance material; The aspect researchs such as the insulating property of electric-field intensity distribution and material.Straight-flow system is in order to ensure the accurate of voltage measurement, require that the electric current increasing measurement mechanism is 1mA or 2mA, considerably increase the thermal power of measurement mechanism like this, operation reliably and with long-term and stable operation, become DC voltage measuring device must faced by outstanding problem.Therefore comprehensive many-sided influence factor, employing appropriate design designs, increase heat dissipation design, some Primary Component hot(test)-spot temperature of voltage divider can not be exceeded for a long time regulation running temperature, can ensure that voltage divider long-time running is reliable, otherwise the performance of Partial key device, insulating material can be caused to reduce, thus cause voltage divider external insulation puncture and have an accident.
Summary of the invention
The purpose of this utility model is to provide a kind of extra-high voltage direct-current measurement mechanism with heat abstractor, to reduce the temperature of insulating cylinder.
The utility model is by the following technical solutions:
Have an extra-high voltage direct-current measurement mechanism for heat abstractor, be provided with the insulating cylinder of heating conductor in comprising, insulating cylinder top is provided with top ring flange, and the top of described top ring flange is provided with radiating element.
Described radiating element is made up of multiple heat radiator, and these heat radiator are with the center of ring flange for round dot distributes ringwise, and wherein, heat radiator forms annular inner ring towards the one end at center, and the other end of heat radiator forms the outer ring of annular.
Spacing between adjacent described heat radiator outwards increases gradually from inner end.
The material of described heat radiator adopts the metal material that heat conductivility is good.
Described heat radiator is made up of metal material.
Described extra-high voltage direct-current measurement mechanism is separately installed with grading ring and lower uniform pressure ring in the upper end of lower end and ring flange.。
Compared with prior art, the utility model at least has following beneficial effect: the utility model is at a series of heat radiator of extra-high voltage direct-current voltage measuring apparatus top ring flange end design and installation, this heat radiator absorbs sends out heat thermogenetic from insulating cylinder inner conductor, then heat is passed through the outside heat conduction of ring flange, thus reduce the temperature in insulating cylinder.
Accompanying drawing explanation
Fig. 1 is structural plan of the present utility model.
Wherein, 1 is upper grading ring, and 2 is lower uniform pressure ring, and 3 is heat abstractor.
Embodiment
Below in conjunction with accompanying drawing, the invention will be described in further detail.
As shown in fig. 1,1,2 is the grading ring on extra-high voltage direct-current voltage measuring apparatus top, and 3 is heat abstractor of the present invention.The utility model discloses a kind of extra-high voltage direct-current measurement mechanism with heat abstractor, be provided with the insulating cylinder of heating conductor in comprising, insulating cylinder top is provided with top ring flange, arranges heat abstractor at the top of described top ring flange.
Described radiating element is made up of multiple heat radiator, and these heat radiator are with the center of ring flange for round dot distributes ringwise, and wherein, heat radiator forms annular inner ring towards the one end at center, and the other end of heat radiator forms the outer ring of annular.Spacing between adjacent described heat radiator outwards increases gradually from inner end.
The material of described heat abstractor adopts the metal material that heat conductivility is good.
Described heat abstractor is positioned at outside ring flange end, extra-high voltage direct-current voltage measuring apparatus top, absorbs and sends out heat thermogenetic from insulating cylinder inner conductor, then outwards transmitted by ring flange by heat.Thus the temperature in reduction insulating cylinder.
