Abstract:
To provide a terminal cover of a breaker which terminal cover can accurately detect a fact that an abnormality has occurred.SOLUTION: A terminal cover 3 of a breaker which is a terminal cover of the breaker being arranged in a board within a power distribution board or a power switchboard comprises: a receiving unit 15; current sensors 111, 112, 113; internal sensors 131, 132, 133; a calculation unit 40; and a determination unit 41. The receiving unit 15 receives a measurement result of an external sensor 9 that is arranged in an external part of the breaker including the terminal cover 3, and that measures an environment condition within the board. The calculation unit 40 calculates at least one of a lower limit value and an upper limit value on the basis of the measurement result of the external sensor 9 received by the receiving unit 15 and a value of current detected by the current sensors 111, 112, 113. The determination unit 41 determines that there is an abnormality when the measurement result of internal sensors 131, 132, 133 is out of a range from the lower limit value to the upper limit value.SELECTED DRAWING: Figure 5
