Abstract
The invention discloses a high-voltage presence indication locking device, which comprises a shell, a front panel and an electronic circuit, wherein the electronic circuit is arranged in the shell; the front panel is provided with indicator lights, an alarm sound element and a detection button; and the indicator lights, the alarm sound element and the detection button are connected with the electronic circuit. When operating personnel incorrectly operates a high-voltage electric cabinet, the high-voltage presence indication locking device disclosed by the invention is capable of sending out a sound and light alarm signal, thereby, an earthed switch can be effectively prevented from being opened and closed when in high-voltage presence, operating personnel can be prevented from entering presence interval by mistake,and the anti-misoperation performance of the high-voltage electric cabinet is greatly improved.
Description
Technical field
The present invention relates to a kind of electrification in high voltage indication blocking device, particularly relate to a kind of fool proof electrification in high voltage indication of electric system mesohigh regulator cubicle blocking device that is used for.
Background technology
In electric system, annual because of reasons such as maloperation or line short have caused huge property loss to country, operating personnel's injures and deaths also happen occasionally.The electrification in high voltage indicating device is that electric system is used for indicating high-tension apparatus and transmission line of electricity whether to have the detection and the indicating equipment of high-tension electricity; Purpose is an alert equipment electriferous state when carrying out overhaul of the equipments, prevents to cause misoperation fault because of being strayed into interval or maloperation equipment.At present; Though the high-voltage potential indicator of domestic use has high pressure indication and blocking function, but because the pilot lamp power supply generally adopts the secondary survey induced voltage of high pressure sensor after rectification, to use to LED, electric current is less; Make the brightness of pilot lamp very dark; Indicative relatively poor to the high-tension apparatus electriferous state, and indicate insensitively, there is the hidden danger of certain manual operation accident.
Summary of the invention
Deficiency to prior art the objective of the invention is to, and the electriferous state of a kind of high brightness flashing signal indication high-tension apparatus is provided and has the electrification in high voltage indication blocking device of warning function.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of electrification in high voltage indication blocking device; Comprise housing, front panel and electronic circuit; Described electronic circuit is located in the housing, it is characterized in that: described front panel is provided with pilot lamp, alarm sound element and test button, and described pilot lamp, alarm sound element and test button all are connected with described electronic circuit.
Aforesaid electrification in high voltage indication blocking device, it is characterized in that: described pilot lamp comprises the locking pilot lamp, unblank pilot lamp and high pressure three-phase electricity pilot lamp.
Aforesaid electrification in high voltage indication blocking device, it is characterized in that: the quantity of described high pressure three-phase electricity pilot lamp is 3.
The invention has the beneficial effects as follows: the pilot lamp that is provided with on the front panel, alarm sound element and test button all are connected with electronic circuit; During operating personnel's maloperation high-voltage electrical cabinet; The present invention can send sound, visual alarm, can effectively prevent to be with the high pressure time-division splice grafting ground switch; Prevent mistakenly entering charged chamber, improved high-voltage electrical cabinet anti-misoperation performance greatly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
For further disclosing technical scheme of the present invention; Now be described with reference to the accompanying drawings embodiment of the present invention: as shown in Figure 1; A kind of electrification in high voltage indication blocking device comprises housing 1, front panel 2 and electronic circuit, and electronic circuit is located in the housing 1; Front panel 2 is provided with alarm sound element 3, locking pilot lamp 4, the pilot lamp 5 of unblanking, high pressure three-phase electricity pilot lamp 7 and test button 6, and pilot lamp, alarm sound element 3 and test button all 6 all are connected with electronic circuit.
The quantity of high pressure three-phase electricity pilot lamp 7 is 3, and the bright expression of 1 lamp one is mutually charged, and 3 all bright expression high pressure three-phase electricity are arbitrary mutually charged, forced blocking, and locking pilot lamp 4 is bright, and alarm sound element 3 sends chimes of doom when maloperation; The high pressure three-phase is not charged, and the pilot lamp 5 of unblanking is bright, and can unblank this moment.Test button 6 can proving installation the intact situation of function.
More than, basic design of the present invention and ultimate principle have been set forth through introduction to listed embodiment.But the present invention never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technical scheme of the present invention of change all should belong to protection scope of the present invention.
Claims (3)
