Abstract

The embodiment of the invention discloses an electric energy recycling device, which comprises a bidirectional controller, a reactor, a current sampler and an intermediate relay, wherein bidirectionalcontroller is used for controlling the output direction of the current; the reactor is used for limiting the voltage drop at the grid side during the commutation of a converter, suppressing harmonicsand the decoupling of a parallel converter set and limiting the jump of the grid voltage or current impact generated during the operation of a grid system; the current sampler is used for collectingstate information of current in an AC circuit and transmitting the collected information to the bidirectional controller; and the intermediate relay controls the power on and off of the circuit. The current input end is connected to a zero line in the circuit, the voltage which is about to enter the reactor in the zero line can be improved through a booster when there is current flowing through the zero line, and the entered current is stabilized by the reactor and then transmitted to a load electrical appliance, thereby achieving the purpose of secondary utilization of the current in the circuit, reducing the waste of current in the circuit, and improving the utilization rate of resources.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and in particular relates to an electric energy recovery and reuse device. Background technique [0002] As the main artery connecting the power generation end and the power consumption end, the transmission line is a key link in the overall grid framework. However, because the geographical environment of the transmission line is often relatively remote, it is often vulnerable to extreme weather (such as typhoons, lightning, ice disasters, etc.) The destruction leads to a series of power accidents such as broken wires and inverted poles, which bring huge economic losses to the society. Therefore, monitoring the meteorological environment parameters of transmission lines and providing timely warnings when severe weather arrives can help power operation and maintenance personnel take effective measures to effectively reduce the loss of the power grid. Sensors collect various micro-meteo...
