Abstract
An arrester resistive current tester allowing direct obtaining of voltage signals from a high voltage bus comprises a main machine, a voltage signal sampling unit, a hook and an insulation rod. The voltage signal sampling unit is connected with one end of the insulation rod, and the voltage signal sampling unit directly obtains the voltage signals from the high voltage bus. The tester is characterized in that the voltage signal sampling unit and the high voltage bus are directly connected, and the voltage signal sampling unit directly acquires the voltage signals from the high voltage bus. The current tester has the advantages that the problem that normal operation of a power system is affected due to the fact that various protection devices conduct protection action possibly when the voltage signals are obtained from the secondary side of a PT cabinet is solved; the problem that arresters for testing long distance require long cables due to the fact that the secondary side of the PT cabinet is concentrated in distribution, and arresters to be tested are disperse is solved; the problem that testing is inaccurate due to the fact that the voltage signals of the secondary side of the PT cabinet and the voltage signals of the high voltage bus have angular difference is solved.
Description
Technical field
The present invention relates to lightning arrester block property current tester device field, more concrete, relate to a kind of lightning arrester block property current tester of directly getting voltage signal from high voltage bus.
Technical background
Lightning arrester block property current tester is to be widely used at present electric system, as the important checkout equipment of one that detects lightning arrester quality, safe operation to electric system has great significance, but the sampling mode of existing arrester resistance current voltage signal exists many drawbacks.
The mode of getting voltage signal from PT cabinet secondary side is current the most frequently used a kind of mode of getting voltage signal.
But; on the one hand; PT cabinet secondary side is conventional wiring place of the many protection opertaing devices of electric system; cause the faults such as short circuit once get herein voltage signal; will cause the protection action of various relevant protection equipment; will certainly have influence on the normal operation of whole electric system, cause irremediable economic loss.
On the other hand, PT cabinet is relatively less in the quantity in power station, the position of its distribution is also more concentrated, and lightning arrester disperses very much, in the time that needs detect more remote lightning arrester, tend to need to be very long test cable voltage signal sampling unit is connected with instrument host, when increasing staff work difficulty, in transformer station, use very long cable also can become staff's potential safety hazard.
Moreover, the voltage signal of PT cabinet secondary side and the voltage signal of high voltage bus exist a differential seat angle, in the process of use lightning arrester block property current tester, this differential seat angle inevitably can be introduced in the measuring error of instrument, affects the accuracy of final measurement.
And the mode of getting voltage signal by the electric field intensity of tablet induction high voltage bus voltage in prior art, the condition of its existence is: at A, B, tablet is placed in the high voltage bus below of tri-parallel distributions of C, described tablet is used for detecting the voltage signal of described high voltage bus B, and described high voltage bus A and C offset completely to the induced voltage of tablet.
But utilizing tablet power taking to press the drawback of aspect is that prior art is difficult to the reference point that finds suitable can meeting that described high voltage bus A and C are offset completely to the induced voltage of tablet.
Summary of the invention
In order to solve, above-mentioned prior art still exists, and the one, get voltage signal from PT cabinet secondary side and may cause various protection equipment protection actions, and then affect this electric system and normally move; The 2nd, PT cabinet secondary side distributes and concentrates, and the lightning arrester of required test disperses, and testing longer-distance lightning arrester need to longer cable; There is differential seat angle in the voltage signal of the 3rd, PT cabinet secondary side and the voltage signal of high voltage bus, causes test inaccurate; And utilize tablet to get the problem that voltage signal is difficult to find suitable reference point, patent of the present invention has proposed a kind of lightning arrester block property current tester of directly getting voltage signal from high voltage bus.
