Embodiment
Be described further below in conjunction with the temperature control electric switch equipment of accompanying drawing to a kind of Novel belt earth leakage protective of the utility model warning device.
In Fig. 1,2,3,1-main contacts, 2-warning circuit contact, 3-power supply unit, 4-alarm lamp, 5-alarm bell, 6-circuit breaker, 7-current driver, 8-pulse generator, 9-comparator, 10-detector, 11-rectifier, 12-amplifier, 13-annular core and winding thereof.
When circuit is short-circuited, short circuit current produces heat through sheet metal, and normally-closed contact, by thermal deformation, separates by sheet metal 1.As shown in Figure 1.Because sheet metal 1 is made up of memory metal material, therefore can return to the original form after temperature reduces, can reuse.
This utility model is designed with leakage protection circuit and warning circuit simultaneously, as shown in Figure 2.When there is electric leakage, leakage protection circuit work, sends triggering signal to upper level circuit breaker, and circuit breaker is disconnected.Leakage protection equipment is made up of annular core and winding 13 thereof, amplifier 12, rectifier 11, signal detector 10, comparator 9, pulse generator 8, current driver 7.Leakage protection circuit top is connected to an annular core 13, and it is tied with winding coil, and the magnetic flux in the situation lower coil not having leakage current is constant, and when electric leakage occurs at switch place, the change of magnetic flux just induces electric leakage signal and sends amplifier 12 to.As shown in Figure 3.Electric leakage signal amplifies by following amplifier 12, sends rectifier 11 to; Rectifier 11 pairs of amplifying signals carry out rectification, produce rectified signal, namely convert direct current signal to, then send signal detector 10 to; Detector 10 pairs of rectified signals are tested, and produce inspection signal, send comparator 9 to; Reference signal compares with inspection signal by comparator 9, produces comparison signal; Comparison signal trigger generator 8, pulse generator 8 sends trip signal, drives circuit breaker 6 to trip by current driver 7.Whole leakage protection circuit is powered by power supply unit 3.After sheet metal deformation, two circuit contacts 2 can trigger alarm circuit, and alarm lamp 4 starts flicker after being energized, and alarm bell 5 sends alarm sound after being energized.Power supply unit 3 is powered for alarm lamp 4 and alarm bell 5.
The temperature control electric switch equipment of a kind of Novel belt earth leakage protective of this utility model warning device needs to install in circuit according to the use of user.Alarm lamp 4 and alarm bell 5 are all connected on a sheet metal contact 2, and power supply unit 3 is connected on another sheet metal contact 2, when sheet metal 1 is by after thermal deformation, two sheet metal contacts 2 can be linked together, connect warning circuit.Leakage protection circuit is independently present near switch; top is connected to an annular core 13; it is tied with winding coil; then be connected to amplifier 12, rectifier 11, signal detector 10, comparator 9 and pulse generator 8 successively; once leak electricity; send trip signal by pulse generator 8 to current driver 7 after electric leakage signal is processed, current driver 7 drives the circuit breaker 6 connect thereon to trip.
When user can use this utility model in the circuit that may be short-circuited and leak electricity.When a short circuit occurs, circuit can be disconnected, and alarm lamp 4 glimmers, alarm bell 5 is reported to the police.When there is electric leakage, leakage protection circuit can order about circuit breaker 6 trip protection circuit.
The utility model provides a kind of temperature control electric switch equipment of Novel belt earth leakage protective warning device; reasonable in design; simple and reliable for structure; have easy to use; practical; result of use is good; the low advantage of cost; the problem needing to change cannot be recovered after not only overcoming conventional temperature control electric switch fuse blows; and the leakage current at switch place can be detected, carry out earth leakage protective, its warning circuit is also for the danger of getting an electric shock provides certain warning function; market potential is large, can commercially promote.
