Abstract

The invention discloses a manufacturing process of a high-power short-circuit protection reactor. The manufacturing process includes the following steps: selecting materials; winding a coil; manufacturing a leading-out copper pipe and a leading-out copper row; welding the leading-out copper pipe with the leading-out copper row; testing pressure and flow; processing and shaping the surface of the coil; preparing before pouring a resistor body; pouring the resistor body; testing a finished product. The manufacturing process is low in cost and high in working efficiency; by the manufacturing process, position deviation or deformation during forming of the coil can be effectively prevented, shape and size of the reactor in large-scale production is ensured to realize standardization, and overall weight of the reactor can be reduced.

Description

Technical field [0001] The invention relates to a manufacturing process of a high-power short-circuit protection reactor. Background technique [0002] The function of the short-circuit protection reactor is to limit the short-circuit current of the transmission line and protect the power equipment. It can reduce the short-circuit current and keep the system voltage unchanged at the moment of short-circuit. Most of the short-circuit protection reactors are produced with the same technology as dry-type hollow shunt reactors. [0003] At present, in the mass production of reactors, from winding, wrapping terminal heads, soldering, wrapping end caps, soldering E-pieces, installing coils, soldering I-pieces, grinding, soldering the bottom plate, and finally dipping and drying, there is always coil formation. The position deviation or deformation occurs at times, which affects the performance of the reactor. In addition, polyurethane is currently used as the packaging material for ins...
