Definitions

  • the present invention relates to an earth leakage detection unit that is arranged between a power source and a load to detect an earth leakage on the load side and an earth leakage breaker that breaks a circuit when an earth leakage occurs, and in particular to an earth leakage detection unit and an earth leakage breaker that are suitable for a case in which a zero-phase current transformer is used for earth leakage detection.
  • a zero-phase current transformer is, as is well known, a device to send currents of all phases through the inner hole of an annular core and, when a so-called secondary current is produced on the annular core, judge that an earth leakage (earth fault) has occurred, and what sends a current between a power supply and a load through the inner hole of the annular core is an earth leakage breaker.
  • the earth leakage breaker is, in general, equipped with an over-current tripping device to break a circuit when an over-current (short circuit) is produced on the load side, together with a leakage tripping device to break a circuit when an earth leakage is detected by an earth leakage detection unit including an earth leakage detection circuit.
  • Such earth leakage breakers and earth leakage detection units include, for example, earth leakage detection units disclosed in PTL 1 and PTL 2, which will be described below.
  • earth leakage detection unit disclosed in PTL 1 among the earth leakage detection units plate-like power supply side conductors corresponding to respective phases of a power supply side circuit are arranged on the one side in the axial direction of a zero-phase current transformer.
  • plate-like load side conductors corresponding to respective phases of load side terminals are arranged.
  • Round rod-like through conductors for all phases are disposed so as to penetrate an annular core of the zero-phase current transformer and pushed against the corresponding power supply side conductors and load side conductors.
  • the power supply side conductors and the load side conductors are connected to each other with respect to each phase with the through conductors penetrating the zero-phase current transformer, and insulation between respective phases is maintained by filling interspaces between the conductors of respective phases with insulating resin, such as silicon and epoxy, and curing the insulating resin.
  • each plate-like power supply side conductor and each plate-like load side conductor are interconnected by a plate-like through conductor in one body in a bifurcated manner in advance, and insulation portions are formed through coating processing with respect to each phase. Then, the conductor members are inserted into an annular core of a zero-phase current transformer in such a way as to stride over the annular core to be assembled into a circuit.
  • both the earth leakage detection unit disclosed in the afore-described PTL 1 and the earth leakage detection unit disclosed in the afore-described PTL 2 have room for improvement in assemblability.
  • the earth leakage detection unit disclosed in the afore-described PTL 1 since interspaces are required to be filled with insulating resin with the power supply side conductors and the load side conductors being connected by the through conductors with respect to each phase, all conductors are required to be positioned accurately. Since bubbles and cracks developing in the insulating resin with which interspaces are filled cause a degradation in the insulation, it is also required to prevent such bubbles and cracks from developing.
  • the present invention is made to solve the above-described problems, and an object of the present invention is to provide an earth leakage detection unit and an earth leakage breaker that make processing of conductor members easy, enable miniaturization of a device, and, in particular, excel in assemblability.
  • JP 4736949 (PTL1), US 2001/022713 and JP 2005347090 recite earth leakage detection units having features included in the preamble of claim 1.
  • an earth leakage detection unit as defined in claim 1.
  • the annular core of the zero-phase current transformer may be perfectly circular, and shapes of cross-sections of the through conductor portions orthogonal to the axis of the zero-phase current transformer may be sectors.
  • the annular core of the zero-phase current transformer may be oval, shapes of cross-sections of the through conductor portions orthogonal to the axis of the zero-phase current transformer may be a combination of sectors and quadrilaterals.
  • an insulating plate member may be interposed between a joining portion of one of the load side conductors and a joining portion of one of the power supply side conductors in proximity to each other.
  • an earth leakage breaker comprising: an open-close mechanism for contacts of a power supply side circuit mounted in a main-body case; an over-current tripping device mounted in the main-body case; and a leakage tripping device mounted in the main-body case.
  • the leakage tripping device includes a combination of an earth leakage detection unit and a trip coil unit.
  • load side conductors are arranged on either one side in an axial direction of a zero-phase current transformer, corresponding to respective phases of load side terminals.
  • Power supply side conductors are arranged on the other side in the axial direction of the zero-phase current transformer, corresponding to respective phases of a power supply side circuit.
  • a through conductor portion(s) corresponding to one phase or two phase is/are continuously fixed to either one(s) of a load side conductor(s) among the load side conductors and a power supply side conductor(s) among the power supply side conductors.
  • Through conductor portions corresponding to the other phases are continuously fixed to the other ones of the other load side conductors and the other power supply side conductors.
  • Each of through conductor portions penetrates the annular core of the zero-phase current transformer to be joined to a joining portion of one of the load side conductors and the power supply side conductors that has a corresponding phase and to which any one of the through conductor portions is not continuously fixed.
  • Each of insulating coating portions is formed at least on the outside of a portion of the through conductor portion continuously fixed to one of the load side conductors and the power supply side conductors at which one of the through conductor portions is continuously fixed.
  • load side conductors and power supply side conductors are arranged on the one side and the other side in the axial direction of a zero-phase current transformer, respectively, in such a way that continuously fixed through conductor portions penetrate an annular core from the one side or the other side in the axial direction of the zero-phase current transformer.
  • insulating coating portions are formed on the outsides of portions of the through conductor portions continuously fixed to the load side conductors and the power supply side conductors, which makes it possible to maintain insulation between the load side conductors and between the power supply side conductors that are mutually adjacent to one of the joining portions. Therefore, it becomes possible to achieve not only an excellence in assemblability but also a miniaturization of a device because it is not required to make the annular core of the zero-phase current transformer have a large inner hole. Furthermore, since each load side conductor or power supply side conductor and a through conductor portion are configured with, for example, a plate-like load side conductor or power supply side conductor and a rod-like through conductor portion in combination, the conductor members are easily processed.
  • the cross-sections of which orthogonal to the axis of the zero-phase current transformer have sectorial shapes enables the inner hole portion of the annular core to be used effectively as a through hole portion for the through conductor portions.
  • the cross-sections of which orthogonal to the axis of the zero-phase current transformer have a combination of sectorial shapes and quadrilateral shapes enables the inner hole portion of the annular core to be used effectively as a through hole portion for the through conductor portions.
  • interposing an insulating plate member(s) between the joining portions, which are in proximity to each other, on either side or both sides in the axial direction of the zero-phase current transformer enables the joining portions, which are in proximity to each other, to be insulated easily and securely.

  • the load side conductors 11T to 11N and the power supply side conductors 12T to 12N are arranged on the one side and the other side in the axial direction of the zero-phase current transformer 8, respectively, in such a way that the through conductor portions 14S and 14N, which are continuously fixed to the load side conductors 11S and 11N, and the through conductor portions 13T and 13R, which are continuously fixed to the supply side conductors 12T and 12R, penetrate the annular core 9 alternately one another from the one side and the other side in the axial direction of the zero-phase current transformer 8, respectively.
  • the through conductor portions 13T, 13R, 14S, and 14N are joined to the joining portions 16T and 16R of the load side conductors 11T and 11R and the joining portions 15S and 15N of the power supply side conductors 12S and 12N, each of which has a corresponding phase and is not continuously fixed, and, as a result, the power supply side conductors 12T to 12N and the load side conductors 11T to 11N are connected to each other with respect to each phase.
  • the insulating coating portions 18S, 18N, and 17R are formed at least on the outsides of the portions of the through conductor portions continuously fixed to the load side conductors 11S and 11N and the power supply side conductor 12R, which makes it possible to maintain insulation between the load side conductors 11T to 11N or the power supply side conductors 12T to 12N, which are mutually adjacent to one of the joining portions 16T, 16R, 15S, and 15N. Therefore, it becomes possible to achieve not only an excellence in assemblability but also a miniaturization of a device because it is not required to make the annular core 9 of the zero-phase current transformer 8 have a large inner hole.
  • each of the load side conductors 11S and 11N and the power supply side conductors 12T and 12R which include the through conductor portions 14S, 14N, 13T, and 13R, respectively, is configured with, for example, a combination of one of the load side conductors 11S and 11N and the power supply side conductors 12T and 12R, which have plate-like shapes, and one of the through conductor portions 14S, 14N, 13T, and 13R, which have rod-like shapes, the conductor members are easily processed.
  • the annular core 9 of the zero-phase current transformer 8 is oval
  • using the through conductor portions 14S, 14N, 13T, and 13R the cross-sections of which orthogonal to the axis of the zero-phase current transformer have a combination of sectorial shapes and quadrilateral shapes enables the inner hole portion of the annular core 9 to be used effectively as a through hole portion for the through conductor portions 14S, 14N, 13T, and 13R.
  • interposing the insulating plate members 19 and/or 20 between the joining portions 15S and 15N and/or the joining portions 16T and 16R, each pair of which are in proximity to each other, on either side or both sides in the axial direction of the zero-phase current transformer 8 enables the joining portions 15S and 15N and/or the joining portions 16T and 16R, each pair of which are in proximity to each other, to be insulated easily and securely.
  • the T-phase, S-phase, R-phase, and N-phase through conductor portions are arranged in such a way as to be inserted alternately from the power supply side and the load side.
  • the through conductor portions corresponding to four poles do not always have to be inserted alternately.
  • the area of proximity between joining portions in proximity to each other increases. If such a case materializes, interposing insulating plate members to maintain insulation prevents any difficulty.
  • the earth leakage detection unit and the earth leakage breaker including a 4-pole circuit that has N-phase in addition to three poles, that is, T-phase, S-phase, and R-phase, was described in detail, a circuit having three poles, namely T-phase, S-phase, and R-phase, may also be acceptable.
  • a through conductor portion corresponding to any one pole may be inserted into the annular core from either one side of the power supply side and the load side, and through conductor portions corresponding to the other poles may be inserted into the annular core from the other side of the power supply side and the load side.
