Problems solved by technology

[0002] The grid structure of the State Grid has become large-scale, and ultra-high voltage and ultra-high voltage will become the main system of China's power grid in the future. The problems and difficulties brought about by it will also increase accordingly. The main problem is that the impact of switching capacitors and reactors on equipment is relatively large. Big
[0003] To improve power quality and reduce equipment maintenance, it is necessary to prevent overvoltage and inrush current generated during the operation of power network circuit breakers, which will affect the insulation, life of the equipment and the stability of the power system, and will also induce malfunction of relay protection and other equipment maintenance into power system operation question on

Abstract

The invention relates to a prefabricated bin for a high-voltage SF6 phase angle control switching breaker. A box is divided into a plurality of compartments, namely an incoming line compartment, a PT (potential transformer) compartment, at least one capacitor compartment, at least one inductor compartment, a transformer compartment and a control chamber. The prefabricated bin is simple in structure, small in occupied area, capable of realizing workshop assembly, low in cost, and convenient to use, maintain and overhaul.

Description

technical field [0001] The invention relates to a prefabricated warehouse of a circuit breaker, which is especially suitable for a prefabricated warehouse of a high-voltage SF6 phase angle controlled throwing and breaking circuit breaker. Background technique [0002] The grid structure of the State Grid has become large-scale, and ultra-high voltage and ultra-high voltage will become the main system of China's power grid in the future. The problems and difficulties brought about by it will also increase accordingly. The main problem is that the impact of switching capacitors and reactors on equipment is relatively large. big. [0003] To improve power quality and reduce equipment maintenance, it is necessary to prevent overvoltage and inrush current generated during the operation of power network circuit breakers, which will affect the insulation, life of the equipment and the stability of the power system, and will also induce malfunction of relay protection and other equi...
