Abstract

The invention relates to a dry-type hollow parallel capacity regulating reactor used for compensation of capacity current of long distance transmission line, belonging to the reactive power compensation device technical field. The reactor comprises an installation base plate, a first high voltage insulator and a primary coil; wherein the first high voltage insulator is connected with the installation base plate, and the primary coil is arranged on the first high voltage insulator. The primary coil is fixedly connected with a secondary coil by a screw and a nut, the secondary coil is arranged above the primary coil, and an adjustable gib with scales is arranged between the primary coil and the secondary coil; the primary coil and the secondary coil are connected in series, the terminal arranged at the primary coil is an outlet terminal, the terminal arranged at the secondary terminal is an inlet terminal, and the inlet terminal and the outlet terminal are all arranged on an aluminum current conducting electrode arm. The invention can obtain different required inductances when a load changes; the capacity of the reactor can change correspondingly along with the change of capacity current of a power supply system; and use and installation are convenient and capacity regulating of a reactor can be realized by regulating the adjustable gib on the reactor.

Description

technical field [0001] The invention relates to a dry-type air-core shunt capacity-adjusting reactor, which is used for capacitive current compensation of long-distance power transmission lines, and belongs to the technical field of electric reactive power compensation equipment. Background technique [0002] At present, the shunt reactor in the power system is mainly used to compensate the capacitive current of the long-distance transmission line and reduce the line loss. The basic principle is to set a certain inductive reactance. When the grid load changes, the capacitive current in the line also changes, but the capacity of the shunt reactor cannot be changed in time. Compensation that affects capacitive currents. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a dry-type air-core shunt capacitor regulating reactor. It is connected in parallel to the low-voltage side of the main transformer of ...
