Abstract
A kind of lightning arrester on-line computing model, it relates to lightning protection equipment field, and what the utility model adopted wakes up, and to be sampling module pass to CPU by by the number of lightning strokes of lightning arrester and current/voltage numeral in the mode of SMS message transmission; The beneficial effects of the utility model are: the utility model can monitor thunder and lightning size by lightning arrester and number of times, and can for the localization of fault of circuit, have great importance to the maintenance of lightning arrester, the utility model can realize the real-time measurement to lightning arrester lightning current.
Description
one, technical field
The utility model relates to lightning protection equipment field, particularly a kind of lightning arrester on-line computing model.
two, background technology
The monitor of electric transmission line lightning arrester domestic at present is mainly divided into two kinds: one is mechanical, is mainly used in monitoring number of lightning strokes and is not with transporting function, another kind is electronic type, number of lightning strokes can be monitored, lightning arrester excess current and with data remote function, these two kinds of lightning arresters all have no idea to monitor the thunder and lightning size by lightning arrester, lightning arrester lightning stream testing apparatus needs uninterrupted continuous firing, because lightning arrester on-Line Monitor Device is arranged on electric power pylon, constant current source cannot be obtained, what substantially adopt is battery powered working method, this power supply mode makes traditional electronic type lightning arrester on-Line Monitor Device can only intermittent work, therefore the real-time measurement realizing lightning arrester lightning current is difficult to.
three, utility model content
For above-mentioned prior art Problems existing, the utility model provides a kind of lightning arrester on-line computing model, its structure is: one end of sampling coil (L1) is connected with lightning arrester low pressure end, the other end of sampling coil (L1) is connected with resistance pressure-dividing network (RP1) one end, the other end of resistance pressure-dividing network (RP1) is by flip-flop circuit (D2) and CPU(D3) data output end is connected, the other end of resistance pressure-dividing network (RP1) is also by signal conditioning circuit (D1) and CPU(D3) data input pin is connected, the other end of sampling coil (L1) is also successively by voltage dependent resistor (VDR) (RV1), divider resistance (R1), voltage dependent resistor (VDR) A(RV2), resistance A(R2) be connected with rectifier bridge (B1), rectifier bridge (B1) is by voltage stabilizing diode (V1), electric capacity (C1) and resistance B(R3), resistance C(R4) with CPU(D3) data input pin is connected, resistance B(R3) and resistance C(R4) between be also provided with resistance D(R5) with the earth be connected, voltage dependent resistor (VDR) (RV1) other end is connected with steel tower, CPU(D3) data output end is connected with SMS message transmission module (G1), CPU(D3) BAT end be greatly connected.
Principle of work of the present utility model is such: adopt dash current sampling coil (L1) that the current value of the lightning current by lightning arrester is converted into measurable magnitude of voltage, by resistance pressure-dividing network (RP1) and signal conditioning circuit (D1) thunderbolt measuring voltage nurse one's health that applicable AD samples voltage range, utilize this voltage to wake CPU(D3 up by flip-flop circuit (D2) simultaneously) carry out the sampling of thunder-strike current value; In addition, by voltage dependent resistor (VDR) (RV1, RV2), divider resistance (R1, R2), and rectifier bridge (B1) forms lightning arrester leakance testing circuit, lightning arrester the current value of leakage current be converted to DC voltage value, and by voltage stabilizing diode (V1), electric capacity (C1), resistance (R3, R4, R5) coating-forming voltage modulate circuit, the conditioning of the detected value of the leakage current of lightning arrester for CPU can the voltage range of Direct Sampling.On the corresponding note receiving trap that the thunder and lightning flow valuve collected and leakage current value can be sent by SMS message transmission module (G1).
The beneficial effects of the utility model are: the utility model can monitor thunder and lightning size by lightning arrester and number of times, and can for the localization of fault of circuit, have great importance to the maintenance of lightning arrester, the utility model can realize the real-time measurement to lightning arrester lightning current.
four, accompanying drawing explanation
Fig. 1 is the utility model electrical block diagram.
five, embodiment
