Practical novel intelligent alternating-current power-grid power-saving device

Abstract

The invention discloses a practical novel intelligent alternating-current power-grid power-saving device, comprising an alternating-current power source, a transformer, a sampling and operating power source, a PL automatic bypass unit, a TY contactless voltage-regulating unit, a control unit KZ, a display module, a protection circuit, a load and a remote control module. By means of the transformer, voltage of the alternating-current power source is matched and converted and then is sent to the TY contactless voltage-regulating unit. The on/off state of the TY contactless voltage-regulating unit is controlled by the PL automatic bypass unit. Power is supplied to the KZ control unit by the sampling and operating power source. Voltage current sample signals are obtained by the KZ control unit from the TY contactless voltage-regulating unit, are analyzed and processed, and then are displayed by the display module. An output end of the load is sampled by the protection circuit and sample signals are sent to the KZ control unit. The remote control module is connected onto the KZ control unit. With a simple structure, the practical novel intelligent alternating-current power-grid power-saving device of the invention achieves high safety, good energy-saving effect and high practicability and economical efficiency.

technical field [0001] The invention relates to the application field of alternating current, in particular to a practical novel intelligent alternating current power saving device. Background technique [0002] At present, the tap terminals of most user transformers are debugged and fixed at one time according to the maximum design capacity of the power grid, which cannot solve the problem of power waste caused by large changes in the remote load current of the power grid. In fact, in those places that are close to power plants or substations, the "umbrella effect" phenomenon makes most electrical appliances receive a power supply voltage much higher than their rated voltage, making them in a state of overvoltage operation for a long time In addition, most high-voltage and high-power motors are running, especially in the process of dragging mechanical loads of low-density media (such as fans, liquid pumps, etc.), often because they cannot be used at any time according to de...

Problems solved by technology

[0002] At present, the tap terminals of most user transformers are debugged and fixed at one time according to the maximum design capacity of the power grid, which cannot solve the problem of energy waste caused by large changes in the remote load current of the power grid

In fact, in those places that are close to power plants or substations, the "umbrella effect" phenomenon makes most electrical appliances receive a power supply voltage much higher than their rated voltage, making them in a state of overvoltage operation for a long time In addition, most high-voltage and high-power motors are running, especially in the process of dragging mechanical loads of low-density media (such as fans, liquid pumps, etc.), often because they cannot be used at any time according to demand. Reduce that part of the unnecessary output power, resulting in a large amount of waste of electric energy over time

Under such circumstances, the AC regulated power supply cannot solve the problem of waste (energy saving)
