A three-phase power source is accessed to a sensing and control circuit which is then electrically connected with a signal searching circuit unit, and the signal searching circuit unit is then electrically connected with a signal processing unit. The structure can monitor a power source for power supply momently, and can avoid fire caused by overvoltage, undervoltage, lightning strike, open phases, overcurrent, short circuit, cross ignition, electric leakage, high temperature, dense smoke, etc. The utility model is arranged in a computer chip, so that various functions can be all perfect, the sensitivity can be very high, and the safety of power supply can be ensured.
Description
The utility model relates to a kind of power supply safety protective device, particularly relates to a kind of three-phase folk power supply safeguard protection watch-dog.
According to the fire department statistics, the fire incident that is caused by power supply accounts for more than 40% of the total accident of national fire.Its main cause is to be widely used in all kinds of protection switches that play the safeguard protection effect on the power supply circuits at present not have intelligent active searching, display circuit fault and in time send the function of prompting, alarm, and the sensitivity of power-off protection is not high yet.The patent No. is 9621136.1 designing technique, on the only suitable single phase power supply source, and the practicality deficiency, control circuit is not advanced yet.
The purpose of this utility model provides a kind of three-phase folk power supply safeguard protection watch-dog, has intelligent active searching, display circuit fault and in time sends prompting, alarm until the function of cutting off whole power supplys, to guarantee Electrical Safety.And can be common on three-phase, the single-phase power supply circuits, the control circuit advanced person, practical.
The purpose of this utility model is achieved in that and comprises standardization source box (1), sensing and control circuit (2), in standardization source box (1), sensing and control circuit (2) are electrically connected by in line plugs and sockets of multicore (19) and signal search circuit unit (3), and signal search circuit unit (3) is electrically connected by in line plugs and sockets of multicore (23) and signal processing unit (4).When doing actual the use, sensing and control circuit (2) are constantly being monitored power supply circuits and detected numerical value are being sent into signal search circuit unit (3) carry out the alternating current-direct current conversion of signals, again the signal after changing send into that signal processing unit (4) is retrieved, a series of routine processes such as analysis, comparison and computing.If result meets intrinsic permissible value, the utility model is only exported demonstration numerical value.If faults such as overvoltage, under-voltage, thunderbolt, the phase failure, overcurrent, short circuit, short sparking, electric leakage, high temperature, high concentration smog appear in result, still in the permissible value scope, the utility model only sends the prompting alarm signal for some, outage after three minutes.Surpass the permissible value scope, can in 20 milliseconds of times, be cut off whole power supplys, to guarantee Electrical Safety.When being used for single phase power supply, as long as insert single phase poaer supply.
Because adopt such scheme, power supply circuits can be guaranteed safety, prevent and the fire incident of avoiding causing and the injury etc. of leaking electricity, and can point out the user to carry out artificial peak-clipping and valley-filling electricity consumption by power supply, reduce expenses.Too high when the switch temperature rise, ETS is super dense, all can obtain timely alarm, and disaster hidden-trouble is eliminated in rudiment.It both had been applicable to needs three phase mains, large-scale public place that power consumption is big, industrial and mining enterprises, and also being applicable to only needs the general single household of single phase poaer supply family.Because the multichannel output current detects respectively, separately control, thus overcome the drawbacks that are out of order and need all have a power failure in a place.Power supply department monitor functions according to this prevents stealing.
