A Current Limiting Reactor Structure for Limiting Overcurrent in Power System

Abstract

The invention relates to the technical field of line protection, and discloses a current-limiting reactor structure for limiting overcurrent in a power system, including a base. The height is too high to continue to contact the spring contactor. At this time, the elastic contactor will disengage from the contact bracket and quickly reset under the action of its own elastic force and contact with the contact bracket II, which shortens the break time during the replacement contact process of the elastic contactor and further improves the stability of the device. The reactor is in contact with the contact bracket II again. At this time, the reactor II and the reactor I are connected to the line together, thereby improving the inductive reactance effect, thereby realizing the effect of adjusting the inductive reactance of the reactor without dismantling and installing. , to avoid the problem of cumbersome operation caused by the disassembly and installation of the traditional reactor when it needs to be adjusted, and to improve the practicability of the device.

Description

technical field [0001] The invention relates to the technical field of line protection, in particular to a current-limiting reactor structure for limiting overcurrent in a power system. Background technique [0002] The current-limiting reactor is a very common electrical component, usually used in the power network, the reactor is essentially an air-core coil without magnetic material, it can be arranged in vertical, horizontal and zigzag three assembly forms according to the requirements, in the circuit When a short circuit occurs in the middle, a large short-circuit current will be generated, and the reactor increases the short-circuit impedance through its own inductance, limits the short-circuit current, and avoids the damage of the electrical components connected to the line by high current. In addition, the reactance The voltage drop on the transformer is relatively large, so it also plays a role in maintaining the voltage level of the bus, making the voltage fluctuat...
