Embodiment Construction

[0014] Embodiments of the oil-immersed split reactor of the present invention: as Figure 1-3 As shown, it includes a closed casing, and a coil 3 is arranged in the casing. The housing includes a housing body 1 with an opening facing upwards and a cover plate 6 sealingly connected to the housing body. The housing body 1 is cylindrical as a whole and its housing wall is corrugated. The cover plate 6 is connected to the shell body through a set of bolts 4, the bolts are evenly distributed and the distance is generally 10-15cm, the gap between the bolts 4 and the cover plate 6 is sealed with nitrile rubber to realize the airtightness of the shell. The shell is made of stainless steel, which can effectively shield the magnetic field. The housing has an oil chamber for containing transformer oil, and the coil 3 is located in the oil chamber. When the reactor is used as a finished product, the oil cavity is filled with transformer oil 2, so that the coil is immersed in the oil.

Abstract

The invention discloses an oil-immersed type split reactor. The oil-immersed type split reactor comprises a coil which is formed by a first winding and a second winding which are arranged coaxially, all envelopes of the first winding and all envelopes of the second winding are sequentially arranged in a crossed mode from inside to outside, the odd layers of the envelopes of the coil form the first winding, and the even layers of the envelopes of the coil form the second winding; the oil-immersed type split reactor further comprises a closed shell which is provided with an oil cavity used for containing transformer oil, and the coil is located in the oil cavity. According to the oil-immersed type split reactor, the transformer oil replaces air to serve as a magnetic flux medium, the insulating strength of the transformer oil is much higher than that of air, magnetic flux can be effectively reduced, and higher voltage can be borne. The transformer oil is high in specific heat, often serves as a cooling agent and is beneficial to heat dissipation of the coil.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to an oil-immersed split reactor. Background technique [0002] Reactors are inductors, which provide inductance values ​​on electrical circuits, and are mainly used to limit short-circuit current and reactive power compensation in lines. The split reactor mainly plays the role of limiting short-circuit current in the line. The structure is a branch circuit with one input and two outputs. During normal operation, the current direction of the two branches is opposite, so that the reactance value of the two branches is reduced, so the voltage loss is small; when a short circuit occurs, the short circuit current can be effectively limited. For example, a hollow split reactor disclosed in a Chinese patent (authorized notification number is CN202736630U) has a coil installed on the insulating support of the reactor, and the coil is composed of a first winding and a second winding coaxi...
