Abstract

The invention relates to the technical field of smoke-fire circuit breakers and discloses a smoke-fire circuit breaker with high detection precision. The smoke-fire circuit breaker comprises a shell, a guide rod is arranged in the shell, an isolating layer is arranged in the shell, an arc extinguish chamber is arranged on one side, close to the guide rod, of the isolating layer, a clamping groove is formed in the arc extinguish chamber, an arc extinguish plate is arranged in the arc extinguish chamber, a sliding plate is slidably connected in the shell, a cutting plate is movably connected in the sliding plate, a buffer rod is arranged on the surface of the cutting plate, and an ignition chamber is arranged in the shell. According to the smoke-fire circuit breaker with high detection precision, through the cooperative use of a reset spring and a limiting rod, the cooperative use of the limiting rod and a ratchet wheel and cooperative use of a rotating rod and the sliding plate, the cutting plate can be limited, the phenomenon that the cutting plate is mistakenly broken can be prevented, meanwhile, resetting of the cutting plate is facilitated, replacement operation of a cut-off guide rod in the circuit breaker is facilitated, and replacement operation of the guide rod is convenient.

Description

technical field [0001] The invention relates to the technical field of pyrotechnic circuit breakers, in particular to a pyrotechnic circuit breaker with high detection accuracy. Background technique [0002] A circuit breaker is a switch control device that can control circuit opening and closing, carrying and breaking current. The circuit breaker has different operating principles due to different places of use. Pyrotechnic circuit breaker is a kind of circuit breaker. A pyrotechnic circuit breaker is a device used in a fire-prone place, which can cut off and protect the circuit by detecting the pyrotechnic situation inside the place to avoid the occurrence of fire. When the existing pyrotechnic circuit breaker is in use, it is prone to false interruption, which will affect the normal operation of the line. When in use, the internal conductor structure is not easy to replace, the replacement operation is inconvenient, and the internal arc extinguishing effect is not good. ...
