Abstract

PURPOSE: To simplify the abnormality detection of an apparatus by making the abnormality detector of a high-tension electric apparatus hold by itself by an electric circuit and by cutting off the power supply of the detection circuit of other apparatus at the same time.
CONSTITUTION: Sense parts 21 to 29 fitted to external walls of high-tension electric apparatus 11 to 19 consists of displacement generators which cause displacement through vibration and limit switches which close contacts 31a to 39a by the displacement. Further, the electromagnetic switch is provided which is equipped with invariable-open contacts 41b to 49b in series to those contact, exciting coils 41x to 49x, and invariable-open contacts 41a-1 to 49a-2 in parallel, and display lamps 51 to 59 are connected to invariable-open contact (a). Here, when apparatus 11 causes a flashover and starts oscillating, contact 31a closes, contact 41b opens by coil 41x, and contacts 41a-1 and 41a-2 close. Therefore, display lamp 51 comes on and even if the vibration attenuates and contact 31a opens, the circuit is held, so that it will keep on lighting. Even if contact 32a or following one closes, the power circuit is disconnected, so that the detection circuit will not be constituted. Therefore, the display lamp will not come on
