Embodiment Construction
[0027] Such as figure 1 As shown, the present invention discloses an airtight permanent magnet circuit breaker cabinet at atmospheric pressure, which is used in power transmission and distribution power equipment, where loads of different natures are switched and frequently operated, and can be used in industrial mines, enterprises, power plants and substations For the protection and control of electrical facilities, it can quickly and reliably eliminate the instantaneous faults and permanent faults of the main line or branch lines before the action of the outgoing line switch in the substation, and quickly reclose to restore power after the fault is eliminated. At the same time, it can be installed on the ring network line , Radiative lines, branch lines and user terminal lines.
[0028]The atmospheric pressure airtight permanent magnet circuit breaker cabinet includes a cabinet body 1, a permanent magnet circuit breaker 2 arranged in the cabinet body 1, a closing knob (unnum...
