Abstract

The invention belongs to the technical field of a middle voltage electric transformation and distribution system and discloses an integrated fixed ISM breaker. The integrated fixed ISM breaker comprises a breaker body, a framework connected with the breaker body, a foundation for mounting the breaker body and the framework, an opening button, a closing button, a control module which is mounted on the framework to control a breaker for closing and opening, a state indictor and an opening and closing state indication device used for determining closing and opening of the breaker body. The integrated fixed ISM breaker is advantaged in that the control module is integrated in a handcart, a closing and opening indication function, a state indication function and a counter function are all integrated on the fixed breaker, and an integration degree is high; the breaker is interlocked, and interlocking with a cabinet is realized; the fixed breaker is set to employ a secondary plug socket, and wiring and maintenance are convenient.

Description

technical field [0001] The invention belongs to the technical field of medium-voltage power transformation and distribution systems, and in particular relates to an integrated fixed ISM circuit breaker. Background technique [0002] Circuit breakers play the role of carrying, breaking and closing current in the power distribution system. At present, most of the circuit breakers involved in the medium voltage power system adopt vacuum breaking technology, and the core component vacuum interrupter is the core component of the circuit breaker. An important part of. With the gradual improvement of the maturity of circuit breakers and related components, the maintenance cycle of medium-voltage equipment is lengthened, and the connection of primary conductive parts of fixed circuit breakers is fastened with bolts, and the electrical connection is reliable. [0003] Whether the handcart is in place in the handcart circuit breaker will directly affect the conduction of the primary ...
