Abstract
The utility model discloses an intelligent circuit breaker which comprises a vacuum circuit breaker solid-sealed polar pole and a box body. The vacuum circuit breaker solid-sealed polar pole comprises a vacuum arc-extinguishing chamber, a lower outgoing line conducting end, an upper outgoing line conducting end, an epoxy resin casing, a voltage sensor, a current sensor, a vacuum sensor and signal lines. The box body is divided by a transverse partition plate into an upper portion and a lower portion, the upper portion is provided with a control room provided with a control unit, and the lower portion is an operating room. Outgoing line terminals of the voltage sensor, the current sensor and the vacuum sensor are arranged at the position of the epoxy resin casing close to the control unit, and all of signal lines connected between the voltage sensor, the current sensor and the vacuum sensor and the outgoing line terminals are fixedly sealed inside the epoxy resin casing. The box body is a shielding box body made from a conducting material. Compared with the prior art, the intelligent circuit breaker solves the problem that an existing intelligent circuit breaker is easily interfered and accordingly the work reliability is influenced.
