本発明は、農耕地で有害獣類の侵入防止用等に使用され
る電気牧柵器における漏電表示装置に関するものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an earth leakage display device in an electric fencing device used for preventing the invasion of harmful animals in agricultural land.
電気牧柵器は、農耕地の周囲に一定の間隔で立設された
杭に碍子を介して張設された種線(裸電線)に、衝撃電
流を流し、この種線に触れた獣類に電撃を与え、獣類を
退散させることを目的とする。Electric pasture fences apply an impulse current to seed wires (bare electric wires) that are strung through insulators to stakes erected at regular intervals around farmland, and are used to kill animals that come into contact with the seed wires. Its purpose is to send electric shocks to drive away beasts.
しかし、種線がたるんで大地に接触したり、種線に草木
が接触したりすると、衝撃電流が大地へ漏電し、電気牧
柵器としての効果が弱くなる。However, if the seed wire sags and comes into contact with the ground, or if plants come into contact with the seed wire, the impact current will leak to the ground, weakening the effectiveness of the electric fence.
通常は高い値であるが、種線が大地にふれたり、種線に
草木が接触したりして、零に近い値まで大幅に変化し、
一般の電気回路に比べて、きわめて異質の電気回路であ
り、電気牧柵器側で、漏電の有無を表示する必要性を生
じ、本発明は、その目的でなされたものである。Normally it is a high value, but when the seed line touches the ground or plants come into contact with the seed line, the value changes significantly to near zero.
This is a very different electric circuit compared to general electric circuits, and there is a need for the electric fencing device to display the presence or absence of electrical leakage, and the present invention was made for this purpose.

なり、1次側に流れる電流が、多くなることを利用し、
この1次側の電流を検出し、この検出量を信号量とし、
発光素子を発光させ、漏電表示するものである。The gist of the present invention is that in an electric fencing machine, the load resistance connected to the secondary side of the converter is low (as the inopedance seen from the primary side becomes low, the inopedance of the primary side is also low). Taking advantage of the fact that the current flowing to the side increases,
This primary side current is detected, and this detected amount is taken as the signal amount,
It causes the light emitting element to emit light to indicate electrical leakage.
以下本発明を図面について説明する。The present invention will be explained below with reference to the drawings.

撃を与え目的とする。As shown in Figure 1: 1. The capacitor/sample (3) is charged from the DC type # (1) through the resistor (2) and the guioto' (5). When this charge is sufficient, the bird starts using the generator (
(W) The bird generates a signal, conducts the thyristor (6), and transfers the electric charge charged in the capacitor (3) to the cathode of the thyristor (6) - the primary side (4') of the output transformer.
- Conde/su (3) - Sudden discharge in the direction of the anode of thyristor (6)
), an impact voltage is generated. and return to its original state,
Repeat the above again. In this way, an impulse voltage is generated at a rate of approximately one time per second, and this is passed through the seed wire to give an electric shock to the animal for the purpose.

て、この出力トラ/スの1次側(4′)に流れる電流を
検出するための検出線輪(9)を第1図のように設け、
その検出量を信号源として漏電表示するものである。In this case, if the load resistance on the secondary side (4'l) of the output transformer is low (i.e., the seed wire is in contact with plants, or the seed wire is in contact with the ground, a collision current leakage occurs). Isn't there?
(if the current is small), the current on the primary side (4') is small. Therefore, a detection coil (9) is provided as shown in Fig. 1 to detect the current flowing to the primary side (4') of this output truss.
The detected amount is used as a signal source to display electrical leakage.
以下第2図に第1実施例を示し、これを説明する。A first embodiment is shown in FIG. 2 and will be explained below.

になった。The detection coil (Q) is connected as shown in FIG. 2 so as to detect the current on the primary side of the output transformer. The detection wire ring (q) is made by winding a thin copper wire (diameter 0.2 yη) 12 times around the primary side (four conductors) of the output tranos. The output is rectified by a diode (10) to generate a DC voltage across the capacitor (11).The capacitor (11) tested using the prototype device according to this example
) was changed as shown in Fig. 3 due to the change in load resistance.

コンデンサ(11)の両端電圧は高くなる。負荷抵抗が

る。However, Conde/Su (3) was 4 MF and the period was about 1 second.゛As shown in Figure 3, as the load resistance decreases,
The voltage across the capacitor (11) increases. A decrease in load resistance means that there is more contact with plants and trees on the seed line,
Since the seed wire comes into contact with the ground and leakage increases, the voltage across this capacitor (11) is measured by an amplifier (12).
The light emitting diode (13) is amplified by a voltage higher than a certain level of this output to indicate a current leakage. Of course, below a certain level, the light emitting diode (Is) i
t. Adjust the amplification amount of the amplifier (12) so that no light is emitted.
次に第4図に第2実施例を示しこれを説明する。Next, a second embodiment is shown in FIG. 4 and will be explained.

いる。The basic configuration is the same as the first embodiment, but when the seed wire force increases by 1, the capacitance between the seed wire and the ground increases, and in this case, the primary side of the output transformer (4 + and oscillating current It is designed to eliminate the effects of this oscillating current.

This oscillating current is rectified and a positive voltage is applied to the capacitor (11').
In order to generate a negative voltage at

た。Attach them in parallel, and set the value of .
When the voltage was changed to infinity, the voltage across the capacitors (II') and (++/l) became as shown in FIG. The voltage on the capacitor (I+') should be on the primary side of the output transformer. However, the higher the load resistance, the larger the imaging current (and the half-wave of the imaging current is added in phase with the main current, so the voltage across the capacitor (1') does not decrease, and the load resistance is almost constant from zero to infinity.

抗が高(なり、振動電波が多くなるほど、高(なる。Eh, the voltage across the capacitor (++'') is thought to be due to the negative half-wave of the imaging current, and naturally the load resistance becomes higher, and the more oscillating radio waves there are, the higher it becomes.

), the light-emitting diode (1'3') is amplified with a voltage above a certain level, and when the load resistance is low, that is, when there is a current leakage, the light is emitted to indicate the current leakage.
当然一定レベル以下では、発光ダイオード(+3’)は

Furthermore, instead of the light emitting diode, radio waves can be transmitted through other switching elements, even in remote locations.
This is extremely useful as it allows you to know the status of electrical leakage.
