Abstract

The utility model discloses a power box, which is a box with a cover; a power input end, a power output end, a creepage protector, a plurality of power sockets, a plurality of output post heads, a flashlight, a horn, a switch and a timer are arranged in the box body of the power box; the power input end is connected with the power output end by a disconnecting link; the power output end is respectively connected with a plurality of power sockets through the creepage protector; a plurality of output post heads, the primary coil of a transformer, and the secondary coil of the transformer are connected with the two input ends of a rectification circuit by the switch; after one of the two output ends of the rectification circuit is connected with the timer in series, the two ends are connected with a capacitance and the flashlight in parallel and connected with a resistance and a voice module in series; the output end of the voice module is connected with the horn. A plurality of protection and caution effects of the power box lead the checking and testing personnel or passengers away from the dangers brought by approaching to the power box, and be able to close the power, thus being safer and more convenient to use the power box.

Description

Power supply box

One, technical field

The utility model relates to a kind of power supply box.

Two, background technology

Power supply box is mainly used in does electrical test usefulness, and power supply box had only creepage protection function in the past, and to " safety instruction " effect of maintenance and testing crew, function is not fairly simple.Have defective vision or people that hearing is bad if having, perhaps do not notice the person of passing by of power supply box, touch because of carelessness, the possibility of electric shock is bigger, promptly exists safe in utilization.

Three, summary of the invention

The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of the safe of safeguard protection and alarm function that have, power supply box easy to use.

For finishing above-mentioned purpose, technical solution of the present utility model is: a kind of power supply box, it is a chest with cover, and power input, power output end, earth leakage protective device, a plurality of supply socket, a plurality of output wiring terminal, flashlamp, loudspeaker, switch and timer are arranged in its casing; Power input connects power output end by disconnecting link, the power end of power output end input earth leakage protective device, the output terminal of earth leakage protective device connects the primary coil of a plurality of supply sockets, a plurality of output wiring terminal and transformer respectively, the secondary coil of transformer is connected two input ends of rectification circuit by switch, after two output terminals, one end of rectification circuit passes through the series connection timer, the resistance and the voice module of two ends order shunt capacitance, flashlamp and series connection; The output terminal of voice module connects loudspeaker.

The two ends of the output terminal of above-mentioned described earth leakage protective device of the present utility model connect pilot lamp 4 earlier, connect the primary coil of supply socket, output wiring terminal and transformer again.

The above-mentioned described rectification circuit of the utility model is a bridge rectifier circuit.

Because the utility model adds voice module and loudspeaker in the automatic power-off protection of electric leakage ground connection, it can send prompting sounds such as " electricity is arranged, and Danger! Keep Away ", can point out the people who has defective vision, and makes it not go near power supply box, thereby has avoided danger.It has also installed flashlamp, can send the light that redness etc. is glittered, and can point out hearing bad people, makes it not go near power supply box, thereby has avoided danger.Timer can regularly do electrical test, and how long test needs, and is just how long fixed, so that timely powered-down.Above-mentioned several heavy protection and warning function make maintenance, testing crew or passerby avoid the danger that brings because of near power supply box, and the timely powered-down of energy, use safer, convenient.

Four, description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of the utility model after uncapping;

Fig. 3 is an electrical block diagram of the present utility model.

As Fig. 1, Fig. 2 and shown in Figure 3; a kind of power supply box; it is one with cover 1 chest 2, and power input 3, power output end, earth leakage protective device 6, two supply sockets 5, two output wiring terminals 9, flashlamp 7, loudspeaker 8, K switch and timers 10 are arranged in its casing.Power input 3 connects power output end by disconnecting link 11, the power end of power output end input earth leakage protective device 6, behind the pilot lamp 4 in parallel of the two ends of the output terminal of earth leakage protective device 6, after its output terminal two output wiring terminals 11 in parallel respectively and two supply sockets 5, its two ends are connected on the primary coil of transformer T, the secondary coil of transformer T is connected by diode D1 by handle switch K, D2, two input ends of the bridge rectifier circuit that D3 and D4 form, after two output terminals, one end of bridge rectifier circuit passes through series connection timer 10, two ends order shunt capacitance C, the resistance R and the voice module 12 of flashlamp 7 and series connection; The output terminal of voice module 12 connects loudspeaker 8.
