If tension in network exceeds admissible norms or just unstable, then in these cases there is a sense to try to lower it. The transformer, but if you do not have it, then it is possible to try to make it make-shifts best of all will be suitable for this purpose.
It is required to you
- To lower tension in network, you will need the extinguishing resistor, the reactive extinguishing impedances, thyristor regulators.
Instruction
1. To receive considerable undervoltage, it is necessary to add big resistance. Try to use for this purpose the extinguishing resistor. This adaptation can be bought in specialized shops, and it is possible and to collect independently. But it is necessary to remember that in the course of use of such extinguishing resistor on it a large number of power senselessly is distinguished.
2. If you need to lower tension in the systems of alternating current, then try to use the reactive extinguishing impedances. In combination with the ordinary condenser the most real condenser power supply will turn out.
3. Tension in a chain without transformer can be lowered by means of thyristor regulators. houseconditionsIt is senseless to assemble independently in them therefore it is better to get ready in specialized shop. Their electronic scheme thanks to the fact that on a half-cycle of alternating current it is possible to operate a delay of turning on of the thyristor allows to change considerably the power brought to loading.
4. If you need to reduce supply voltage in chains not with variable, and with a direct current, then in this case arrive as follows. In a chain consistently connect a stabilitron, microassembly stabilizer or instead of it it is possible to connect the pulse converter. The choice of the second device has to be made, based on necessary extent of undervoltage of food. All above-mentioned electronic devices work in the same way, as well as semiconductors. It follows from this that it is better to apply them if you have a certain range of knowledge in the field of electronics.
