Embodiment
It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, the batch meter of the present embodiment circuit structure that comprises casing 10 and be arranged in casing 10.Circuit structure comprises transformer 20 summation current transformer 30.Current transformer 30 is electrically connected with transformer 20 by the first wire 40.Current transformer 30 is connected with the second wire 50.Described first wire 40 has chopper switch.Second wire 50 has the subscriber connection away from current transformer 30.Second wire 50 has notch part 51.Expose at the core of notch part 51 place second wire 50.
The batch meter of application the present embodiment, the second wire 50 arranges notch part 51, exposes at the core of notch part 51 place second wire 50.Before needs are changed current transformer 30; first the chopper switch on the first wire 40 is closed; carry out at notch part 51 place again ground protection (metering is changed show exclusively wire clamp on notch part 51; ground wire is connected with the core exposed), then carry out replacing current transformer 30 and operate.Said structure, without the need to carrying out power-off by closing falling fuses device to transformer 20, decreasing the frequent operation to falling fuses device, avoiding fuse cutout to damage, and simple to operate, can alleviate the labour intensity of staff.
As shown in Figure 1, in the batch meter of the present embodiment, circuit structure is three.Three second wires 50 of three circuit structures are respectively the zero line, live wire and the ground wire that connect user.
As depicted in figs. 1 and 2, in the batch meter of the present embodiment, batch meter also comprises breach protector.Breach protector is removably disposed in notch part 51 place.Breach protector have block notch part 51 block position and dodge notch part 51 dodge position.In the present embodiment, breach protector is breach protective jacket 60.Breach protective jacket 60 is set on the notch part 51 of the second wire 50.The sidewall of breach protective jacket 60 has the opening for installing the second wire 50.Opening is positioned in protective jacket main body 61 and along the axial direction of protective jacket main body 61 and arranges.When current transformer 30 changed by needs, breach protective jacket 60 is in and dodges position, namely take off breach protective jacket 60; When batch meter normally runs, breach protective jacket 60 is in and blocks position, be set in by breach protective jacket 60 on the notch part 51 of the second wire 50, make it cover the core exposed completely.When can ensure so normally to run, the corrosion resistance of the second wire 50 and insulativity, accomplish safety, stable power-supplying.
