Voltage sampling circuit provides high voltage protective and low-voltage variation: line voltage is after sampling is calculated; in 0.5 second, always between 260V to 270V, should be that line voltage is abnormal, controller makes drive circuit drive the relay cut-off switch; stop socket output, the safety of protection electrical appliance.Due to some areas electricity shortage, or increase high-power electric appliance temporarily, cause line voltage fluctuated, the electrical appliance use is both undesired also may damage electrical equipment, at this moment gives power-off protection.
Wrong line protection: when higher level's socket of this socket, as zero line and the live wire of wall socket or other conversion socket, or center line and phase line, during the wrong of position, after wrong line detection circuit judgement, microcomputer controller will can not drive the output of relay engage relay switch; Thereby eliminate the potential safety hazard of wrong line electricity consumption.
Surge protection: this surge mainly refers to the electrical network surge voltage; the power supply zero line of factory building ` office building ` residential quarters; the broken string that often has the stolen ` natural calamity of loose contact ` to cause etc. causes electrical appliance moment of 220V to be raised to 380V; perhaps mistake such as construction maintenance etc. is received 220V on 380V; when voltage surpasses 270V; the surge testing circuit can detect in the very first time, and in 3 milliseconds fast driving relay relay switch, the generation of avoiding burning electrical appliance and fire.
Described Intelligent safe power socket, the interior fixedly sleeve of jack, sleeve comprises L utmost point sleeve, N utmost point sleeve and PE utmost point sleeve, L utmost point sleeve, N utmost point sleeve and PE utmost point sleeve are connected with solid conductor respectively, and are connected with control board by relay.Its advantage is: solid conductor reduces contact resistance, reduces heating, has also just reduced contact fault, strengthens its reliability.
Described Intelligent safe power socket, be provided with manual leakage tests button on housing, by the detection of electrical leakage magnet ring, with control board, be connected.Its advantage is: because electric leakage is directly connected to people's life security problem, for meeting the standard of zero tolerance, designed electric leakage manual test function test; If through pressing the test of test key, relay switch can reliably disconnect output acousto-optic hint before electricity consumption, prove that creepage protection function is effectively, can relievedly use.
Described Intelligent safe power socket, surface of shell is fixed with the ground wire indicator light be connected with control board.Its advantage is: by having or not the detection of ground wire, when ground wire is arranged, indicator light can be not bright, when without ground wire, control board can drive light the ground wire indicator light with the warning consumer networks do not protect ground wire.But by this function also having or not of bigness scale user ground wire.
Described Intelligent safe power socket, socket circuit is connected with control board by lightning protected circuit.Its advantage is: select piezo-resistance and the gas discharge tube of the large discharging current of high-quality 5KA, after being optimized Combination Design, solved the ageing failure problem that the piezo-resistance due to leakage current brings, guaranteed that this function is long-time effectively reliable; When lightning impulse is arranged, minute two-stage and differential mode common mode full guard, effectively prevent that thunder and lightning from damaging electrical equipment and disaster hidden-trouble.
Intelligent safe power socket, be provided with the Ding Lishi shutter in jack.Jack must meet the requirements of insertion force, just can insert, and has protected so reliably child to play and Danger Electric shock risk that the false touch electrified body of being grown up causes.The L utmost point is connected with release, and the electricity protection circuit that exceeds the quata adds the dual-overload protection structure of release, guarantees to be unlikely to burn out socket and electrical appliance.
Reliably errorless for guaranteeing all safety protection functions, self control section carries out circuit design according to the high pressure that can bear 500V, guarantees the inherently safe under daily voltage fluctuation and abnormal conditions.
