Abstract
Analog pulse generating means, it is characterized in that comprising box body, be arranged on that simulation PD pulse signal in box body is produced circuit, produced simulation PD output of pulse signal interface that circuit is connected with simulation PD pulse signal, the control knob of control simulation PD pulse signal power, this control knob is resistance-type control knob.Compared with the prior art the utility model, to have in cable local discharge on-line checkingi process the advantage that can be played quantitative and qualitative analysis evaluation to cable partial discharge and the larger effect of assignment test by the simulation PD pulse signal that injects and the comparative analysis of true PD signal.
Description
Technical field:
The utility model relates to a kind of power equipment state monitoring technical equipment, is particularly fully applied in cable local discharge on-line monitoring technique field.
Background technology:
The detection determination methods whether power cable exists shelf depreciation (PD) has obtained in testing laboratory and the on-the-spot checking running the PD case of cable, but have much on earth for the PD signal occurred in the cable, which type of level is the extent of injury be in, signal apparent amount detected by detection system and the signal magnitude relation at signal source place be what etc., at present, be all need further analysis and research.No matter be test in testing laboratory or the PD at scene, the probability of happening of PD is all very little.Therefore, simulate PD signal generation apparatus (PG, Pulse generator) and just seem necessary in cable partial discharge test or research.Like this, simulation PD pulse signal is injected when not affecting cable and running to cable in the test running cable, by analysis mode PD signal propagation characteristic in the cable and in PD source location position fixing process by the simulation PD pulse signal that injects and the comparative analysis of true PD signal, immeasurable effect will be played to the quantitative and qualitative analysis evaluation of cable partial discharge and assignment test.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of analog pulse generating means that can be played quantitative and qualitative analysis evaluation to cable partial discharge and the larger effect of assignment test in cable local discharge on-line checkingi process by the simulation PD pulse signal that injects and the comparative analysis of true PD signal.
The utility model realizes like this, comprise box body, be arranged on that simulation PD pulse signal in box body is produced circuit, produced simulation PD output of pulse signal interface that circuit is connected with simulation PD pulse signal, the control knob of control simulation PD pulse signal power, this control knob is resistance-type control knob.
Here, it is two right that simulation PD output of pulse signal interface has, and being for a pair weak signal output interface, is for a pair strong signal output interface.
Control knob is divided into six gears, when corresponding weak signal exports, the gear of control knob is 2pC, 5pC, 10pC, 20pC, 50pC, 100pC, and when corresponding strong signal exports, the gear of control knob is 100pC, 250pC, 500pC, 1000pC, 2500pC, 5000pC.
Total on/off button and corresponding pilot lamp is provided with in box body positive dirction face.
During use, the sensor port of wanted Injection Signal is connected to by the BNC Y-track adopting coaxial signal line to make, because rig-site utilization tested object cable length and junction style are all different, therefore in use need to regulate analog pulse signal to export size, so that testing apparatus receives suitable semaphore according to actual conditions.The analog pulse signal that this device exports enters by the cable of side by sensors coupled, put in testing apparatus carry out analyzing and processing through being transmitted to the next cable splice office that then decanting point position is got back in signal reflex, thus can grasp the propagation characteristic of Partial discharge signal in tested cable and actual reflection interval situation.
Compared with the prior art the utility model, to have in cable local discharge on-line checkingi process the advantage that can be played quantitative and qualitative analysis evaluation to cable partial discharge and the larger effect of assignment test by the simulation PD pulse signal that injects and the comparative analysis of true PD signal.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the stereographic map of display simulation PD output of pulse signal interface;
Fig. 3 is the stereographic map at the utility model back side.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises aluminium matter box body 2, the simulation PD pulse signal be arranged in box body 2 produces circuit, produce simulation PD output of pulse signal interface that circuit is connected with simulation PD pulse signal, the control knob 1 of control simulation PD pulse signal power, and this control knob 1 is resistance-type control knob.
As shown in Figure 2, here, simulation PD output of pulse signal interface has two to (three interfaces (7,8,9), one of them interface 8 is common interface), and a pair (8,9) are weak signal output interface, and a pair (7,8) are strong signal output interface.
Control knob 1 is divided into six gears, when corresponding weak signal exports, the gear of control knob 1 is 2pC, 5pC, 10pC, 20pC, 50pC, 100pC, and when corresponding strong signal exports, the gear of control knob 1 is 100pC, 250pC, 500pC, 1000pC, 2500pC, 5000pC.
Total on/off button 3 and corresponding pilot lamp 4 is provided with in box body 2 positive dirction face.
As shown in Figure 3, this device adopts No. 5 rechargeable type batteries (being arranged on the position in direction, the back side) to provide working power in power mode, can also directly adopt the interchange being arranged on rear direction to turn direct current 12V power port 5 and provide working power to this device, pilot lamp 6 display provides power supply whether to be in normal condition.
