Abstract

An integrated circuit breaker of the invention is characterized by comprising a chassis, a circuit breaker arc extinguishing chamber, an isolating switch, a circuit breaker grounding switch, an operating mechanism, an interlocking mechanism, an insulating cylinder and an insulating crank arm. A circuit breaker switch cabinet comprises the circuit breaker, and further comprises a switch cabinet body, an upper cabinet door, a lower cabinet door, a current transformer, a voltage sensor and a lightning arrester. The integrated circuit breaker and the switch cabinet have the advantages of miniaturization and integration.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a high-voltage switch cabinet. Background technique [0002] In power systems, switchgears are widely used as power distribution equipment. The main function of switchgear is to switch, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. [0003] There are various structures of existing switch cabinets, and customers continue to put forward new requirements for the design of switch cabinets. For example, some customers have very high requirements for the volume of the switchgear, requiring the size of the switchgear to be less than 500x900x1800mm, but the various parameters of each electrical component (inc...
