Description
Technical field
The utility model relates to charged testing tool in a kind of ultra-high-tension power transmission line, the adjustable test rod of especially a kind of sparking distance.
Background technology
In present power delivery networks because between the metal section and part and shaft tower of each insulator, all have stray capacitance between lead, the actual voltage of being shared of each insulator and inequality in the insulator chain.It is extremely uneven distributing along the voltage of insulator chain, falls maximum near the insulator voltage of lead, littler from the insulator two ends pressure drop that lead is healed far away, and when insulator during near the shaft tower cross-arm, insulator voltage falls and raises.Insulator chain is longer, and voltage distributes more inhomogeneous, causes the insulation damages at some position more easily.So the measurement that voltage is distributed is also just very necessary.The at present general fork of short circuit fork for making with tinsel on the insulating bar top, the steel cap of fork one end and following insulator, the other end spark will occur near tested insulator steel cap, judges the voltage condition on the insulator according to the spark situation.Though this method can be checked out zero resistance insulator, can not detect the concrete numerical value that voltage distributes.
The utility model content
The purpose of the utility model is to provide a kind of test rod that can confirm accurately that voltage distributes.
The purpose of the utility model realizes through following technical proposals: the utility model is made up of sounding rod and insulating bar; Said sounding rod is made up of upper contact head, high-voltage capacitance, discharging gap adjustment chamber and the following contact of series connection successively; Said insulating bar comprises insulating bar and following insulating bar; Last insulating bar hollow also links to each other with test rod, and following insulating bar is arranged at the insulating bar lower end, links to each other through gap adjusting lever in the last insulating bar cavity and discharging gap adjustment chamber.
The beneficial effect of the utility model is: simple in structure, easy to use, and can accurately confirm the concrete numerical value that voltage distributes, and, can prevent effectively that because of sparking distance discharge short circuit the good insulation performance element causes flashover relatively through high-voltage capacitance.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with concrete embodiment the utility model is done explanation further.
As shown in Figure 1; The utility model is made up of sounding rod 8 and insulating bar 9; Said sounding rod 8 is made up of upper contact head 1, high-voltage capacitance 2, discharging gap adjustment chamber 3 and the following contact 4 of series connection successively, and said insulating bar 9 comprises insulating bar 6 and following insulating bar 7, and last insulating bar 6 hollows also link to each other with test rod 8; Following insulating bar 7 is arranged at insulating bar 6 lower ends, links to each other with discharging gap adjustment chamber 3 through the gap adjusting lever 5 in last insulating bar 6 cavities.
The sparking voltage value of good discharging gap in indoor school in advance, and on the insulating bar 7 scale is being set down.Like this, at the scene upper contact head 1 and following contact 2 are connected respectively to insulator sheet two ends, rotate insulating bar 7 down, drive gap adjusting lever 5 and change discharging gap,, can read the sparking voltage value that on scaleplate, is marked corresponding to clearance distance until beginning discharge.
