FIELD: electricity. ^ SUBSTANCE: invention relates to electrical engineering and can be used for changing voltage in a network. The device for varying voltage in network is a connection of a set of capacitors or modified capacitor for "pumping" electrical energy from a network with "transformation" of supply voltage. Shortcomings related to manufacture of transformers, which require large material inputs and use of expensive raw material are excluded, as well as servicing and need for the user to settle for power, provided by the transformer substation or some other system for changing voltage. The device can be installed into an open line of the high side. Installation of a capacitor in the circuit leads to increase in cos å, which is good for the circuit as a whole. The invention does not transform electrical energy, but pumps it out of the network, as it were. Pumping power depends on the capacitance of the device. Large capacitance is required for a high power user. Knowing the required power and voltage of the user and the high side, it is easy to calculate capacitors and standardise the proposed device as a whole. The device allows for considerable decrease in power used by the network due to that, the source of electrical energy supports voltage harmonics and not power in the network. ^ EFFECT: use of a capacitor as a transformer. ^ 2 cl, 2 dwg |
