Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail:
As shown in Figure 1, this utility model is control the load control device that air switch disconnects, including intelligent electric meter 1 and air switch 2, air switch 2 is provided with two groups of cabling paths, intelligent electric meter 1 electrically connects with air switch 2, is additionally provided with control bypass 3, controls to be in series with in bypass 3 switch control terminal 4 of intelligent electric meter 1, the two ends controlling bypass 3 are connected on two groups of cabling paths of air switch 2, and the two ends controlling bypass 3 lay respectively at front side and the rear side of air switch 2.
nullThis utility model is in use，This utility model is arranged on the end of incoming cables of user，Electrical network line connects intelligent electric meter 1 after air switch 2，Then user from intelligent electric meter 1 leading-out terminal go between electricity consumption，In intelligent electric meter 1, the electricity charge are used up、When needing power-off，Intelligent electric meter 1 starting switch controls end 4，Switch control terminal 4 is connected，Now control bypass 3 conducting，Now owing to portion of electrical current has walked around air switch 2 through controlling bypass 3，Cause that the electric current on the two groups of cabling paths flowing through on air switch 2 exists difference in size，And then cause that air switch 2 starts power-off protection，Thus having reached the purpose of power-off，If the intelligent electric meter of user 1 still arrearage，Control bypass 3 to turn on all the time，Timely air switch 2 is closed by force，Air switch 2 still can disconnect because round electric current is different，Prevent the generation of stealing electricity to a certain extent，User swipes the card after power purchase again，Control bypass 3 disconnection and electric current is zero，Now come and go equal with the two-way electric current on air switch 2，Air switch 2 can be kept closed，Now circuit can normal power supply.
Specific embodiment 1, two groups of cabling paths described in the utility model, including connecting the path of phase line and connecting the path of zero line, control bypass 3 one end and be connected in phase line, its junction point is positioned at phase line and enters the front end before air switch 2, controls bypass 3 other ends and is connected on zero line to be positioned at the rear end of air switch 2.
Specific embodiment 2, controls bypass 3 one end and is connected on zero line, and its junction point is positioned at zero line and enters the front end before air switch 2, controls bypass 3 other ends and is connected in phase line to be positioned at the rear end of air switch 2.
Specific embodiment 3, as in figure 2 it is shown, be additionally provided with switch 6 in described control bypass 3.Described switch 6 is remote switch.In needs are to intelligent electric meter maintenance or debugging subscriber's line circuit during the function such as earth leakage protective; by remote switch, control is bypassed 3 to disconnect; now intelligent electric meter is only capable of playing electrical measurement effect; will not the power-off because of arrearage; now personnel carry out overhauling, debugging; it can be avoided that the interference brought because of intelligent electric meter, it is ensured that maintenance and debugging effect.
Further, in order to avoid there is the danger that air switch 2 is short-circuit, cause big electric current, described control bypass 3 is in series with load 5, the electric current controlling air switch 2 is reduced by means of load 5, by the resistance of regulating load 5, controlling in less milliampere rank by the electric current controlled in bypass 3, first less electric current ensure that the use safety of circuit and components and parts, secondly the electric energy that smaller current consumes is less, it is possible to lowers consumption, save electric energy, environmental protection.
