AC-DC high-voltage insulator passive tester

The invention is a alternating and direct high-tension insulator passive tester composed, by the cabinet, left measuring plate, right measuring plate, the measuring bar, the measuring bar fixed flange and the insulation pole, the measuring bar fixed flange installs in the cabinet beginnings and ends, the measuring bar fixes on the measuring bar fixed flange, left measuring plate and right measuring plate are installed, on the two sides of measuring bar fixed flange, left measured the plate and right measuring plate parallel, left measuring plate the insulator to examine the electric circuit board, left side plate opens the window, the cabinet and the measuring bar fixed flange installs on the insulation pole. When examination, puts the instrumentation in the electric field which the insulator is at, causes the instrumentation between two measuring bars passively to have the voltage differential pressure, carries on through the sensitive unit the signal the primitive collection, enlarges, the filter and the exchange enlargement after direct current obtains can the integrity recognition signal, sends in after the rectification the signal the sampling to carry on the analysis classification, and carries on processing by the processor, then to processes after from the launcher the data transmission to in the ground in receiving device. This invention can in the charged situation, quick examine the voltage distribution situation of the alternating and direct electric material insulator prompt, accurately discovers the hidden danger of the insulator.
