Abstract
The invention provides a new distribution connection method and device applicable to a family distribution control box. An electrical wiring diagram of the device is shown in the appended drawings that a firing line, a null line and a ground line on the outer side are respectively connected to the input end of a three-pole leakage circuit breaker, the firing line and the null line of the output end of the three-pole leakage circuit breaker are connected to the input end of a two-pole leakage circuit breaker, and the ground line of the output end of the three-pole leakage circuit breaker serves as a common ground wire (capable of being connected to the shell of a load) of the family distribution control box; the output end of the two-pole leakage circuit breaker is connected with the load, and a lighting source can be directly connected out from the firing line and the null line of the output end of the three-pole leakage circuit breaker. By the arrangement, an original connection method of family distribution is changed, and electrical safety and reliability are greatly improved.
Description
Technical field
The present invention relates to the new connection of a kind of distribution and device thereof, be applicable to family's distribution control box, the new connection of this distribution can solve device housings electric leakage and the contact of outside ground wire is bad, and the person that ground wire electrification causes suffers electric shock and unsafe problem.
Background technology
Existing its circuit connecting of family expenses distribution control box; its conventional connection as shown in Figure 1; household appliances shell electric leakage as user; some electric current will be shunted fast by ground wire; cause earth leakage protective device inflow current and flow out electric current unequal (difference is in 30mA left and right); cause the two poles of the earth earth leakage protective device action, excised the power supply of load end, protected user's personal safety.But the shell of this connection household electrical appliance is to follow the ground connection of system to connect together, if system earth is bad, and system earth is (outside factor) during dangerous voltage extremely, and the shell of household electrical appliance also exists dangerous electrical leakage voltage by the connection of system ground wire.Oneself leakage switch separating brake likely, because existing electrical leakage voltage, ground wire also can bring potential safety hazard to user, many household electrical appliance itself do not leak electricity, and load power source is turned off, but cause electric shock and injures and deaths event under this situation, to occur often.
Summary of the invention
In view of above-mentioned technical deficiency, the invention provides the new connection of a kind of family expenses distribution and device thereof, be applicable to family's distribution control box, this device electrical wiring schematic diagram is as shown in 2: outside live wire, zero line and ground wire are connected on respectively the input of three utmost point residual current circuit breaker, the live wire of three utmost point residual current circuit breaker outputs, zero line is connected on the two poles of the earth residual current circuit breaker input, and the ground wire of three utmost point residual current circuit breaker outputs is as the public earth connection as family's distribution control box (can directly be connected with the shell of load).The load of the two poles of the earth residual current circuit breaker output termination, mains lighting supply can directly pick out from live wire and the zero line of three utmost point residual current circuit breaker outputs.This connection is when user load appearance electric leakage (producing leakage current by shell), the two poles of the earth residual current circuit breaker will trip, and when external ground bad, and during with dangerous voltage, user touches power device shell, if there is electric shock, causes three-pole breaker action at once, cut off the electricity supply and guarantee user's safety, greatly improved the safety and reliability of household electricity.Especially the family's distribution in TN--C--S power supply-distribution system is used protection against electric shock better effects if.
The present invention adopts following scheme to realize: the new connection of a kind of household electricity and device thereof are by three-pole breaker, the two poles of the earth circuit breaker, a plurality of single-pole switchs, wire, the parts such as casing form, it is characterized in that: outside live wire, zero line and ground wire are connected to the input of three utmost point residual current circuit breaker, the live wire of three utmost point residual current circuit breaker outputs, zero line is connected on the two poles of the earth residual current circuit breaker input, and the ground wire of three utmost point residual current circuit breaker outputs is as the public earth connection (can directly be connected with the shell of load) of family's distribution control box.The load of the two poles of the earth residual current circuit breaker output termination, mains lighting supply can directly pick out from live wire and the zero line of three utmost point residual current circuit breaker outputs.This connection changes the connection of original family distribution, greatly improves electrical safety and reliability.
The novel uniqueness of the present invention, implementation is simple and reliable, specifically practical, can be widely used in home distribution box, improves the safety of household electricity.
Accompanying drawing explanation
Fig. 1 is background technology electrical schematic diagram
Fig. 2 is electrical wiring schematic diagram of the present invention
Fig. 3 is that embodiment of the present invention equipment is arranged schematic diagram.
Embodiment
Fig. 2 is embodiment of the present invention electrical schematic diagram, and Fig. 3 is that embodiment of the present invention equipment is arranged schematic diagram.They are the example that the invention provides the new connection of a kind of family distribution and device.In Fig. 3, order 1 is casing, and order 2 is three utmost point residual current circuit breaker, and order 3 is casing earthing bar, and order 4 is the two poles of the earth residual current circuit breaker, and order 5 is illumination single-pole switch, the connecting to neutral row that order 6 is casing, and order 7 is wire.Live wire at Fig. 2 peripheral, zero line and ground wire are connected on respectively the input of three utmost point residual current circuit breaker, the live wire of three utmost point residual current circuit breaker outputs, zero line is connected on the two poles of the earth residual current circuit breaker input, and the ground wire of three utmost point residual current circuit breaker outputs is as the public earth connection as family's distribution control box (can directly be connected with the shell of load).The load of the two poles of the earth residual current circuit breaker output termination, mains lighting supply can directly pick out from live wire and the zero line of three utmost point residual current circuit breaker outputs.This connection is when user load appearance electric leakage (producing leakage current by shell), the two poles of the earth residual current circuit breaker will trip, and when external ground bad, and during with dangerous voltage, user touches power device shell, if there is electric shock, cause three-pole breaker action, cut off the electricity supply and guarantee user's safety, with reference to Fig. 1 at once, if external ground is bad, and during dangerous voltage, in casing, ground wire current potential improves, and human body touches shell can produce electric shock, but the two poles of the earth residual current circuit breaker, because of the bad meeting of outside ground connection tripping, causes electric shock accidents.So the method for Fig. 2 electrical wiring of the present invention can improve reliability and the fail safe of household electricity greatly.
The foregoing is only preferable example in the embodiment of the present invention, allly according to the present patent application the scope of the claims, do impartial change and modify, all should belong to covering scope of the present invention.
