Description
Technical field
This utility model relates to house power distribution technical field, is specifically related to a kind of earth leakage protective time-controlling arrangement.
Background technology
When house power distribution, electrical equipment is typically and single-phase socket grafting carries out normal power supply; and single-phase socket should consider earth leakage protective factor when wiring, single-phase socket be can guarantee that time delay can reclose single-phase socket connection circuit after earth leakage protective circuit disconnects automatically.Therefore, for meeting above-mentioned functions requirement, it is necessary to a kind of earth leakage protective time-controlling arrangement of design.
Summary of the invention
For the deficiencies in the prior art, this utility model aims to provide one and not only has a creepage protection function, and can the earth leakage protective time-controlling arrangement that automatically recloses of time delay after earth leakage protective circuit disconnects.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of earth leakage protective time-controlling arrangement; including RCCB, A.C. contactor, the time relay and single-phase socket; described RCCB, A.C. contactor and single-phase socket are sequentially connected in series, and the time relay is connected electrically between RCCB and A.C. contactor and its outfan is connected with A.C. contactor.
Further, described RCCB be frame size rated current be 63A, setting current be 16A, rated residual operating current be 30mA, the electric leakage trip action time be the bipolar breaker of plastic casing of 0.1s.
Further, the rated current of described single-phase socket is 25A.
This utility model has the advantages that
This utility model one earth leakage protective time-controlling arrangement; its RCCB, A.C. contactor and single-phase socket are sequentially connected in series; the time relay is connected electrically between RCCB and A.C. contactor and its outfan is connected with A.C. contactor; not only there is creepage protection function, and time delay can automatically reclose circuit after earth leakage protective circuit disconnects.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of this utility model a kind of earth leakage protective time-controlling arrangement.
In figure: 1, RCCB；2, A.C. contactor；3, the time relay；4, single-phase socket.
Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment, the utility model will be further described, in order to the clearer technological thought understanding that this utility model is claimed.
This utility model one earth leakage protective time-controlling arrangement as shown in Figure 1, including RCCB 1, A.C. contactor 2, the time relay 3 and single-phase socket 4, wherein RCCB 1 be frame size rated current be 63A, setting current is 16A, rated residual operating current is 30mA, the electric leakage trip action time is the bipolar breaker of plastic casing of 0.1s, the rated current of single-phase socket 4 is 25A, RCCB 1, A.C. contactor 2 and single-phase socket 4 are sequentially connected in series, the time relay 3 is connected electrically between RCCB 1 and A.C. contactor 2 and its outfan is connected with A.C. contactor 2.
Operation principle of the present utility model is: its RCCB 1, A.C. contactor 2 and single-phase socket 4 are sequentially connected in series; the time relay 3 is connected electrically between RCCB 1 and A.C. contactor 2 and its outfan is connected with A.C. contactor 2; not only there is creepage protection function, and time delay can automatically reclose circuit after earth leakage protective circuit disconnects.
For a person skilled in the art, can technical scheme as described above and design, make other various corresponding changes and deformation, and within all these changes and deformation all should belong to this utility model scope of the claims.
