Using an electric shepherd for cattle provides high-quality grazing and reduces efforts to organize it. This means that a certain area of pasture will be limited, and the animal will not be able to leave it. It does not require additional labor. With all the responsibilities copes electronic equipment, which can be done by hand. This kind of fence is live and powered by a generator. In this case, the cattle does not receive any damage in contact with it.
The device and the principle of operation of the equipment
Modern livestock is almost no need of such labor as shepherds. They were replaced by advanced technologies that allow you to establish high-quality control over livestock in the grazing areas. The electric fence system will not allow cows to go beyond the pasture.
This means that cattle will be exposed to a current of 3 mA in contact with the fence, which creates a certain discomfort. The animal will not want to experience the effect of the current again and will try not to come close. Such power is not dangerous and does not have harmful effects on the cattle organism, even if it is dairy calves or milk cows.
The generator operates from a 220 V outlet and produces high voltage pulses. It can be connected to solar panels.
Also, an electroshepherd is able to operate from batteries with a power of 9-12 V. The device includes a ground pole, a special cable, connectors, springs for the main elements of the fence, conductors, as well as voltage isolators. The design is quite simple, so the installation does not require recourse to specialists. Before installing the support must be purchased.
If we consider the device in the complex, then this is a fence made of wire without insulation, which is fixed on supports made of metal or plastic. They, in turn, are equipped with insulators. The height of the wire is set depending on the growth of animals that graze on pasture. For cows, it is advisable to draw the first line 60 cm from the ground, the second 110 cm. At least 60 current pulses with a power up to 12 kW are usually supplied per minute.
Installing an electric shepherd with his own hands is performed in the following steps:
- marking of the territory where the location of the generator, supports, aisles are indicated;
- digging down the pillars around the perimeter of the pasture, taking into account the landscape, where the longest distance between them is allowed at 10 m;
- installation of the gate, which will allow free passage of personnel, equipment, animals;
- installation of insulators at the desired height from the ground, which is selected depending on the height of the animal;
- installation of conductors on insulators using special connectors;
- connection of lines between supports.
The electric shepherd can be of different power, a stronger one is needed when the fence covers a very large area, in the herd there are aggressive individuals or animals with long hair.
More about the installation steps
First of all, when all the work is done by hand and the sketch is ready, it is necessary to install poles for the gate and around the perimeter. The entrance width is optimal from 2.5 to 4.5 m. The insulators are screwed into the pillars with the slot upwards - for conductors. On wooden supports is a prerequisite. The connector will help secure the conductor to the insulator with several turns. If there are two lines, they are also connected by a vertical jumper. This is provided every 200-300 m. A high-voltage cable is laid above the wicket so that the current is not interrupted.
Connectors must be of high quality, otherwise they will quickly deteriorate from corrosion. A conductor is inserted into them and tightened for better contact. But the lines can not be connected or connected by nodes, as this leads to sparking. Tensioners can be used to reduce vibrations, which will also eliminate sagging.
After fixing all the lines and other elements, it is necessary to install the generator using fasteners. The ground pole deepens by 80 cm near it. If the ground is dry, more than one device can be installed.
It is imperative that high-quality grounding is required, which must be located at a distance of more than 10 m from the grounding of buildings and other objects. The lightning rod is a necessary part of the device and is connected to the electronic fence.
After that, the generator is connected to the ground and lightning conductor, and then connected to the power supply. You need to check the action with a tester. When working properly, there should be no arcing, clicks, and the fence voltage should be from 4.0 kV to 10 kV.
