Description
Technical field
The invention belongs to test of lightning arrester technical field, is to be related to a kind of test of lightning arrester servicing unit more specifically.
Background technology
In electric power overhaul, electrical test teams and groups carry the duty that power equipment running status is monitored and diagnosed
Duty, this requires electrical test teams and groups quickly and accurately to obtain test data, judges equipment running status.Wherein, keep away
The experiment of thunder device occupies a big chunk that electrical test teams and groups all work.
In routine test, test of lightning arrester is mainly arrester direct current 1mA voltages（U1mA）And letting out under 0.75U1mA
The measurement of leakage current.U1mA be gapless metal-oxide lighting arrester by 1mA DC currents when, be tested arrester both ends electricity
Pressure value.The U1mA of Zinc-Oxide Arrester is measured, mainly checks whether its valve block makes moist, aging, whether determines its performance
Meet the requirements.Direct current 1mA reference voltage levels are typically equal to or greater than the peak value of arrester rated voltage.
When leakage current under 0.75U1mA is that tested arrester both ends apply voltage 0.75U1mA, arrester is flowed through in measurement
Leakage current.0.75U1mA DC voltages are typically higher than maximum functional phase voltage, predominantly detected under this voltage long-term
Allow whether operating current meets regulation.Because there is direct relation in the life-span of this electric current and Zinc-Oxide Arrester, typically same
Leakage current is inversely proportional with the life-span at a temperature of one.
Because arrester infield disperses in station, need frequently to carry when being tested arrester and experimental rig,
Job site is changed, this just with the addition of difficulty again to originally cumbersome work, and because arrester is large number of, ground connection and wiring are numerous
It is trivial, it is necessary to frequently dismount, take a large amount of manpowers and time, operating efficiency is low.
