Abstract
The utility model discloses a 10kV high-voltage switch cabinet false earthing switch electrified switching on-prevention acousto-optic alarm. The acousto-optic alarm includes a button battery, a manual switch, a buzzer, an LED lamp, a switch earthing locking sheet and a capacitance extraction device which are in series connection successively. According to the 10kV high-voltage switch cabinet false earthing switch electrified switching on-prevention acousto-optic alarm of the utility model, the acousto-optic alarm is additionally arranged at the exterior of a 10kV high-voltage switch cabinet, such that the acousto-optic alarm can emit alarm signals before electrified switching on of an earthing switch performed by a worker, and therefore, the worker can be prompted, and misoperation can be avoided. The 10kV high-voltage switch cabinet false earthing switch electrified switching on-prevention acousto-optic alarm is advantageous in simple structure and low cost.
Description
Technical field
The utility model relates to a kind of warning device, particularly the anti-charged mistake of a kind of 10kV high-tension switch cabinet splice grafting ground cutter audible-visual annunciator.
Background technology
The 10kV high-tension switch cabinet does not have the blocking device of the charged closure of ground connection cutter, and when following situation occurring: 1, electrification display damages; 2, the staff observes that the electrification display angle is incorrect, light is too strong; 3, the staff forgets the observation electrification display; As continuing operation, the three-phase shortcircuit accident of charged mistake splice grafting ground cutter will appear.
The utility model content
Technical problem to be solved in the utility model provides the anti-charged mistake of a kind of simple in structure, cheap 10kV high-tension switch cabinet splice grafting ground cutter audible-visual annunciator.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
The anti-charged mistake of a kind of 10kV high-tension switch cabinet splice grafting ground cutter audible-visual annunciator comprises button cell, hand switch, hummer, LED lamp, switch ground connection locking sheet and the electric capacity draw-out device of connecting successively.
The utility model installs an audible-visual annunciator additional outside the 10kV high-tension switch cabinet, make the staff before charged splice grafting ground cutter, and alarm sends sound and light alarm, and the prompting staff avoids maloperation.The anti-charged mistake of this 10kV high-tension switch cabinet splice grafting ground cutter audible-visual annunciator is simple in structure, cheap.
Description of drawings
The 10kV high-tension switch cabinet that Fig. 1 provides for the utility model is prevented the electrical block diagram of charged mistake splice grafting ground cutter audible-visual annunciator.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
From the utility model embodiment shown in Figure 1 as can be known:
The anti-charged mistake of the utility model 10kV high-tension switch cabinet splice grafting ground cutter audible-visual annunciator comprises button cell 1, hand switch 2, hummer 3, LED lamp 4, switch ground connection locking sheet 5 and the electric capacity draw-out device 6 of connecting successively.
Outside the 10kV high-tension switch cabinet, install the utility model additional, closed hand switch 2, before charged splice grafting ground cutter, alarm sends sound and light alarm, and the prompting staff avoids maloperation.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other embodiment easily according to guiding theory of the present utility model, and these embodiments all are included within the scope of the present utility model.
