Description

Technical Field

[0002] The detuning device is a damping device that protects the primary side of the voltage transformer and is used to eliminate the resonance of the voltage transformer in the power grid. The current-sensitive detuning device is a type of detuning device, which is connected in series between the neutral point of the PT and the ground. Under normal operation, the current-sensitive detuning device is in a low-impedance state and does not affect the system parameters and PT performance; when the system fault generates excitation energy, the current-sensitive detuning device suddenly changes to a high-impedance state, changes the resonance parameters, and consumes the excitation energy, suppressing the PT excitation current below 200mA, ensuring that the voltage transformer is not burned and the PT fuse is not blown.

By rotating the first circular gear 270, the two slide bars 280 equipped with tooth rows 281 are driven to slide, thereby driving the two sliders 250 to slide closer to or away from each other, thereby adjusting the position of the sliders 250. It should be noted that the rotation of the first circular gear 270 can be driven by a reciprocating motor to enable the first circular gear 270 to rotate counterclockwise or clockwise.
