Abstract

The invention discloses a tank-type circuit breaker, which comprises a base, a shell, current transformers and a mechanism case, wherein the shell is arranged on the base; the current transformers are arranged at two sides of the shell; the mechanism case is arranged at one end of the base; a connecting lever box is arranged on the mechanism case; an arc extinguish chamber and a static contact are arranged in the shell; the arc extinguish chamber and the connecting lever box are in transmission connection; a basin-type insulator is arranged at the outer side of the static contact; a lower grading ring, an outlet porcelain sleeve and an upper grading ring are arranged on each current transformer; each lower grading ring, each outlet porcelain sleeve and each upper grading ring all are fixedly connected with one another in sequence; and a wiring terminal is arranged on each upper grading ring and is electrically connected with the static contact. The tank-type circuit breaker is convenient to operate, high in structure stability, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a tank circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into For high-voltage circuit breakers and low-voltage circuit breakers, the division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. [0003] Circuit breakers can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off the circuit when they are severely overloaded, short-circuited, or under-voltage. Its function is equivalent to a fuse-type switch. Combination with overheat and underheat relays, etc., and general...
