Adjustable reactance current limiting reactor

Abstract

The adjustable reactance current limiting reactor comprises a reactor shell, a conducting rod is fixedly connected to the position, close to the bottom, of an inner cavity of the reactor shell, a coil is arranged at the center of the edge of the outer side of the conducting rod in a sleeving mode, and binding posts are fixedly connected to the positions, close to the left side and the right side, of the bottom of the reactor shell. The bottom ends of the coils penetrate through the bottom of an inner cavity of the reactor shell and are fixedly connected with the adjacent binding posts, conducting rings are arranged at the positions, close to the left end and the right end, of the edge of the outer side of a conducting rod in a sleeving mode, and through mutual cooperation of mechanisms such as an L-shaped rod, a contact, a rotating rod, a transmission gear, a sliding block, a rack, an insulation connecting rod and a control box, the electric reactor can be stably connected. Current limiting and circuit protection effects can be realized, and buffering and noise reduction effects on the reactor can be realized through mutual cooperation of mechanisms such as a fixed block, a connecting rod, a frame body, a movable block, a first spring, a limiting box, a movable rod and a second spring.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an adjustable reactance current-limiting reactor. Background technique [0002] With the rapid development of the power system, the capacity of single machine, the capacity of power plants, the capacity of substations, the increase of load and load density in cities and industrial centers, and the interconnection between power systems have led to the continuous increase of the short-circuit current in the power system. At present, Excessive short-circuit current or even exceeding the standard has become an important factor restricting the development of the power grid. Replacing switches is one of the means to solve the problem of short-circuit current exceeding the standard. However, substations with excessive short-circuit current are generally hub substations. The equipment and grounding grid also need to be replaced. Although the replacement of the switch has no effec...
