Problems solved by technology

[0003] Due to the high voltage level and large capacity of large-scale high-coupling split reactors, the coils of this type of product have large dimensions. The largest coil diameter is about 2mm and the height is about 2m. In order to ensure the integrity of the product, it is necessary to cast two layers of coils on Together, this increases the difficulty of pouring

Abstract

The invention discloses a pouring technique of electric reactor coils. The pouring technique comprises the following steps: S1, castables are pre-heated, mixed, stirred and degassed; S2, a pouring die is pre-heated; S3, a wound coil is placed in the preheated pouring die; S4, the degassed castables are added into the preheated pouring die in S3 and vacuum pouring is performed on the degassed castables; S5, post curing is performed on the coil undergoing vacuum pouring, S6, demoulding is performed on the coil undergoing post curing and an electric reactor coil is produced. The electric reactor coil using the pouring technique has the advantages of full and uniform pouring without bubbles, and good electric properties. Through strictly controlling the temperature, vacuum degree, time and pouring flux in the pouring process, full and uniform pouring without bubbles of the coil is ensured, and mechanical strength of the coil is good. Through long-time post curing, mechanical strength of the coil is fully ensured.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a casting process for reactor coils. Background technique [0002] The high-coupling split reactor is a key technology for the research and engineering application of large-capacity short-circuit current breaking devices, and there is currently no technical specification for the equipment. Large-scale high-coupling split reactor coils have large dimensions, and have very strict requirements on casting equipment, materials, and casting processes. [0003] Due to the high voltage level and large capacity of large-scale high-coupling split reactors, the coils of this type of product have large dimensions. The largest coil diameter is about 2mm and the height is about 2m. In order to ensure the integrity of the product, it is necessary to cast two layers of coils on Together, this increases the difficulty of pouring. [0004] Therefore, it is necessary to develop a casting process...
