Be to reach technological means and the effect that predetermined utility model purpose is taked for further setting forth the utility model, below in conjunction with accompanying drawing and preferred embodiment, alarm detector embodiment, structure, feature and effect thereof to according to the transformer station that the utility model proposes are described in detail as follows:
Relevant aforementioned and other technology contents of the present utility model, Characteristic can be known to present in the following detailed description that cooperates with reference to graphic preferred embodiment.Explanation by embodiment, when can being to reach technological means and the effect that predetermined purpose takes to be able to more deeply and concrete understanding to the utility model, yet appended graphic only provide with reference to the usefulness of explanation, the utility model is limited.
Be the synoptic diagram of colleting alarming signals such as Fig. 1, the alarm detector of this transformer station comprises: AC power control flow 10, a PCM 21, with the integrated PCM four-wire interface 31 of a PCM 21, the 2nd PCM 22, with integrated the 2nd PCM four-wire interface 32 and the power supply audible-visual annunciator 30 of the 2nd PCM 22.
Wherein, described AC power control flow 10 has some contacts, and the incoming end of this AC power control flow 10 is connected with the signals collecting end of transformer station, and in the present embodiment, the signals collecting end of transformer station is civil power 100; AC power control flow 10 1 side joint ground, and be provided with the switch J11 that is connected with the earth terminal of AC power control flow 10 in the AC power control flow 10.
A described PCM four-wire interface 31 is the end station, and an end of a PCM four-wire interface 31 is connected with M line 311, and this M line 311 is connected with the switch J11 of AC power control flow 10, and described switch J11 is between the contact end and M line 311 of AC power control flow 10; Between a described PCM four-wire interface 31 and the 2nd PCM four-wire interface 32 channel 23 that is connected is each other arranged, this channel 23 is so that be communicated with between a PCM four-wire interface 31 and the 2nd PCM four-wire interface 32; The 2nd PCM four-wire interface 32 is main website, and the one end is connected with a PCM four-wire interface 31 by described channel 23, and its other end is connected with E line 321, and connects described power supply audible-visual annunciator 30 by this E line 321.
Be provided with direct current squealer Y in the power supply audible-visual annunciator 30, when power supply audible-visual annunciator 30 ground short circuit, direct current squealer Y can send the warning sound.
