Accompanying drawing explanation
Fig. 1 is a kind of structural framing figure of the charged open alarm device of panel box of the present invention.
Fig. 2 is the another kind of structural framing figure of the charged open alarm device of panel box of the present invention.
Embodiment
The invention provides the charged open alarm device of a kind of panel box, as shown in Figure 1, it comprises the travel switch be arranged in panel box, working current testing circuit, main control module and audible-visual annunciator.Wherein, the test side of working current testing circuit is connected in the distribution work supply line of panel box, and the current signal output end of working current testing circuit is electrically connected to the current signal collection terminal of main control module.The alarm signal output ends of main control module is electrically connected with the controlling alarm end of audible-visual annunciator, when current signal for inputting at its current signal collection terminal is non-vanishing, send alerting signal by alarm signal output ends to audible-visual annunciator, trigger audible-visual annunciator and carry out sound and light alarm.Travel switch is closed type, be arranged on the cabinet door position of panel box, and its installation site makes travel switch to be subject to the extruding of cabinet door and to make the electrical connection of switch contacts disconnection to electrical contact end by its contact under the state of cabinet door closedown, the electrical contact end of travel switch is connected in the current supply circuit of main control module and audible-visual annunciator.
In the charged open alarm device of panel box of the present invention, by travel switch, work on off control is carried out to main control module and audible-visual annunciator, when the cabinet door of panel box is closed, the contact of travel switch is subject to the extruding of cabinet door and makes the electrical connection of switch contacts disconnection to electrical contact end, thus the current supply circuit of main control module and audible-visual annunciator is disconnected, main control module and audible-visual annunciator all quit work, to save energy consumption; After the cabinet door of panel box is opened, the contact of travel switch is no longer subject to External Force Acting, thus travel switch recovers closed conducting state, and connect the current supply circuit of main control module and audible-visual annunciator, main control module and audible-visual annunciator then start live line work.Simultaneously, by working current testing circuit, the distribution work supply line to panel box carries out current detecting, and the current signal detected is exported to the current signal collection terminal of main control module, after the cabinet door of panel box opens triggering main control module and audible-visual annunciator live line work, if the current signal of current signal collection terminal input is non-vanishing, main control module general rule is crossed alarm signal output ends and is sent alerting signal to audible-visual annunciator, trigger audible-visual annunciator and carry out sound and light alarm, reach the effect of charged warning, alert notes charged danger, thus help the generation reducing panel box mistakenly entering charged chamber accident.
As further improvement project, be directed to the situation that there is multichannel power distribution work supply line in some panel boxs, on the panel box stated on the invention charged open alarm device scheme basis, as shown in Figure 2, working current testing circuit also can design multiple, the test side of the plurality of working current testing circuit is connected in the multichannel power distribution work supply line of panel box respectively, for detecting the electric current of multichannel power distribution work supply line in panel box respectively, the current signal collection terminal of main control module also can design multiple, be electrically connected with the current signal output end of multiple working current testing circuit respectively, in addition, the alive circuit indicating module with multiple pilot lamp can also be set up in system, simultaneously main control module is also set up multiple pilot lamp and to be powered output terminal, be electrically connected with the feeder ear of multiple pilot lamp in alive circuit indicating module respectively, and in main control module, record the corresponding relation that multiple current signal collection terminal and multiple pilot lamp are powered between output terminal, when current signal for inputting at current signal collection terminal is non-vanishing, to corresponding pilot lamp power output terminal export high level, trigger corresponding pilot lamp in alive circuit indicating module to light.Thus, the charged open alarm device of panel box of the present invention is except can to except the charged enabling of panel box in addition sound and light alarm, can also correspondingly indicate multiple distribution work supply lines charged situation separately in panel box by the pilot lamp on alive circuit indicating module, be convenient to operating personnel and the distribution work supply line in panel box is checked, keeped in repair.
In sum, the charged open alarm device of panel box of the present invention can implement sound and light alarm when the charged enabling of panel box, reach the effect of charged warning, alert notes charged danger, thus helps the generation reducing panel box mistakenly entering charged chamber accident; And the charged open alarm device of panel box only starts work after the cabinet door of panel box is opened, and is in the state of quitting work under the cabinet door closure state of panel box, can economy system operating power consumption; In addition, the panel box that there is multichannel power distribution work supply line can also be used for, multiple distribution work supply lines charged situation separately in panel box be indicated, is convenient to operating personnel and the distribution work supply line in panel box is checked, keeped in repair.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
