Detailed description of the invention
Below in conjunction with each accompanying drawing, the present invention is described in further detail.
Fig. 1 is the FB(flow block) of the inventive method.The present invention gets an electric shock or the fiery zero line bearing calibration of earth leakage protective device, it is characterised in that comprise the following steps: 1. electric shock or earth leakage protective device identify the live wire or zero line accessed when closing a floodgate；2. if live wire or zero line wiring are correct, then can close a floodgate；If live wire or zero line wiring error, then cannot disconnect immediately after closing a floodgate or closing a floodgate, or report to the police, until fire zero line wiring error could be closed a floodgate or stop alarm after being corrected.Wherein, described fiery zero line wiring error be corrected after state, can be remembered, it is also possible to do not remembered.Can be remembered, after referring to that fire zero line is corrected, after power-off and restoring electricity, can keep or automatically restore to the wiring state before power-off, not remembered, after referring to that fire zero line is corrected, after power-off and restoring electricity, revert to the wiring state before fire zero line is corrected.
Fig. 2 is the systematic schematic diagram of the present invention.In Fig. 2; the input power live wire L and neutral conductor N of electric shock or earth leakage protective device 1 are identified by fire zero line identification device 2; if fire zero line wiring is correct; get an electric shock or earth leakage protective device 1 can close a floodgate; otherwise fire zero line identification device 2 will lock up electric shock or earth leakage protective device 1 is allowed to close a floodgate; or report to the police (both desirable one, it is possible to simultaneously carry out).At this moment user can operate fire zero line correcting unit 3, or fire zero line identification device 2 directly drives fire zero line correcting unit 3, and correction is got an electric shock or the fiery zero line wiring of earth leakage protective device 1 so that get an electric shock or earth leakage protective device 1 can normally work.
Fire zero line correcting unit 3 be configured with two kinds.One is memory-type, it is possible to when power interruption recovering is powered, and keeps or automatically restores to the wiring state before power-off.Another kind is non-memory-type, when power interruption recovering is powered, reverts to the wiring state before fire zero correction.
Specific embodiment 1:
In Fig. 2, fire zero line identification device 2 can be any to be capable of identify that power supply fire zero line and export control signal or the circuit of sound and light alarm and device.The present embodiment have employed current-limiting resistance and neon tube series connection, and one connects mains neutral line, the touch electrode of the push-button switch button Face of a contact electricity or earth leakage protective device 1 by terminals N.Under normal circumstances, the terminals L in Fig. 2 should connect power firestreak, and terminals N should connect mains neutral line.If power firestreak has been received N mistakenly; mains neutral line has been received L mistakenly; getting an electric shock or earth leakage protective device 1 power supply when user presses the button connection, the touch electrode on inevitable contact button surface, neon tube luminous triggering follow-up circuit pinning is got an electric shock or earth leakage protective device 1 is allowed to close a floodgate.One of ordinary skill in the art both knows about many lockings and gets an electric shock or the method for earth leakage protective device.Such as, connect electric shock or the tripping relay of earth leakage protective device or testing button short circuit forces electric shock or earth leakage protective device disconnect immediately after closing a floodgate.In the present embodiment, zero line identification device 2 action, connect and get an electric shock or the tripping relay of earth leakage protective device so that get an electric shock or trip immediately after earth leakage protective device 1 combined floodgate, it is achieved that to getting an electric shock or the locking of earth leakage protective device 1.
Fire zero line correcting unit 3 includes one or one group switch, it is possible to correction fire zero line wiring.In the present embodiment, the user discover that fire zero line wrong makes electric shock or earth leakage protective device to close a floodgate, the toggle switch just stirred in fire zero line correcting unit 3 changes electric shock or the part line of earth leakage protective device 1, its result is: 1, change fire zero line wiring, such as, exchange electric shock or the power input fire zero line wiring of earth leakage protective device 1, or the sensor being connected to collector surface and power firestreak due to fire zero line wiring error is reconnected to collector surface and mains neutral line, electric shock or earth leakage protective device 1 is made can correctly to test the potential difference between the neutral conductor and electrical equipment appearance；2, the fiery zero line wiring of fire zero line identification device 2 input is corrected so that fire zero line identification device 2 recognizes correct power supply fire zero line wiring thus releases getting an electric shock or the locking of earth leakage protective device 1.Owing to waved switch need not power supply to maintain on off state, even if restoring electricity after power cut-off, waved switch is still within the position after correction again, it is achieved that to the memory of state after fire zero line correction.
Specific embodiment 2:
Embodiment 2 is with embodiment 1, except for the difference that, after fire zero line identification device 2 recognizes power supply fire zero line wiring error, sends sound and light alarm, the fiery zero line wiring correction in reminding user operation fire zero line correcting unit 3 to complete such as embodiment 2.After fire zero line is corrected, fire zero line identification device 2 recognizes correct power supply fire zero line wiring thus stop alarm.
Specific embodiment 3:
Embodiment 3 is with embodiment 1, and except for the difference that, fire zero line correcting unit 3 includes one or group relay switch, and relay is controlled by fire zero line identification device 2.After fire zero line identification device 2 recognizes power supply fire zero line wiring error; control the relay adhesive in fire zero line correcting unit 3 immediately; relay switch state changes, and the potential difference between the neutral conductor and electrical equipment appearance can be correctly tested in the fiery zero line wiring changing electric shock or earth leakage protective device 1.This correcting mode is when running into power cut-off, relay can be owing to discharging without power supply, and relay switch returns to original state, after service restoration, needing to restart the identification to fire zero line and again complete the correction to fire zero line, belonging to can not the mode of operation of memory correction state.
Specific embodiment 4:
Embodiment 4 is with embodiment 3, except for the difference that, fire zero line identification device 2 and fire zero line correcting unit 3 working power include lithium battery, when running into power cut-off, lithium battery starts power supply, fire zero line identification device 2 and fire zero line correcting unit 3 are worked on, and the correcting state maintaining fire zero line is constant.Belong to the mode of operation of memory correction state.
Specific embodiment 5:
Embodiment 5 is with embodiment 3, except for the difference that, fire zero line identification device 2 also includes non-volatile memory cell (such as, EEPROM, electric capacity etc.) it is used for the duty (adhesive still discharges) of meter relay, when restoring electricity after power cut-off, fire zero line identification device 2 is according to the record information of non-volatile memory cell, automatic control relay adhesive or do not control relay adhesive, has reached the purpose of memory correction state.
The foregoing is only the preferred embodiments of the present invention, not thereby limit the scope of the claims of the present invention.Every equivalent structure utilizing description of the invention and accompanying drawing content to do or flow process conversion, or directly or indirectly apply in other relevant technical fields, the most in like manner it is included in the scope of patent protection of the present invention.
