Abstract
The utility model discloses a novel metering box, which is arranged on a distribution transformer, wherein the distribution transformer comprises a distribution transformer high-voltage inlet wire wiring end and a distribution transformer low-voltage outlet wire end, the distribution transformer low-voltage outlet wire end is arranged on a current transformator box arranged on the distribution transformer, an electricity meter box is connected with the current transformator box through cables, and the electricity meter box and the current transformator box are made into a separated mode. Through separating the current transformator box from an electricity meter, the utility model increases the distribution transformer primary and secondary safe distance, so the safety performance of the metering equipment is greatly improved, leading wires of secondary cables adopt armors, and the safety and the antitheft effect can be ensured.
Description
Technical field
The utility model belongs to power supply measuring equipment technical field, particularly a kind of novel batch meter.
Background technology
All adopt three electric energy meters to join the three-phase four-wire system mode of three current transformers for the radio area metering device, instrument transformer, electric energy meter, once, secondary line all is contained in the narrow and small batch meter, batch meter is directly sat up straight the outlet column at step down side, its shortcoming shows as: 1, batch meter is narrow and small, it is not enough that electric energy meter, instrument transformer are installed safe distance, once, secondary line is staggered installs maintenance inconvenience.2, primary line is close to ammeter in the distribution transforming heating that is in operation, case, and primary line overload or bad contact heating all influence the accurate metering of ammeter, instrument transformer.3, checking meter need be to stand, and inconvenience is dangerous again.4, owing to there is not can't install the short-circuiting means of current transformer yet, cause calibration, change the table power failure of all must operating a switch, when giving user's inconvenience, unnecessary other shell that draws reduces the useful life of other shell, and frequent stopping sent, distribution transforming will be born the prominent load variations that causes, and is unfavorable for long-term stability, healthy operation.
The utility model content
The utility model provides a kind of accurate measurement, easy for installation, security of operation, novel batch meter that reliability is higher.
A kind of novel batch meter, be arranged on the distribution transformer, described distribution transformer comprises distribution transforming high pressure end of incoming cables and distribution transforming low pressure leading-out terminal, described distribution transforming low pressure leading-out terminal is arranged on the current transformer case on the distribution transformer, described ammeter box is connected with the current transformer case by cable, and described ammeter box and current transformer case are set to released state.
The cable of described connection ammeter box and current transformer case is an armoured cable.
The utility model is by separating current transformer with ammeter, make distribution transforming one, the secondary safe distance increases, make the security performance of measuring equipment improve greatly, the secondary cable lead-in wire adopts armouring, guarantee safety, antitheft, cable adopts many colors, makes quick and easy for installationly, prevents mis-wired, guide to the stand below under the ammeter box, conveniently check meter, changing and verification, mainly is that the ammeter box that separates has enough spaces that special junction box is installed, and voltage is separated, circuit closed, could change kilowatt-hour meter by on-load, and the power failure of once needn't operating a switch has ensured the fail safe and the power supply reliability of equipment, also creates conditions for far copying on later on.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel batch meter, be connected on the distribution transformer 1, described distribution transformer 1 comprises distribution transforming high pressure end of incoming cables 3 and distribution transforming low pressure leading-out terminal 2, described distribution transforming low pressure leading-out terminal 2 is arranged on the current transformer case 4 on the distribution transformer 1, described ammeter box 6 is connected with current transformer case 4 by cable 5, and described ammeter box 6 is set to released state with current transformer case 4.
Described connection ammeter box 6 is an armoured cable with the cable 5 of current transformer case 4.
The utility model is by separating current transformer with ammeter, make distribution transforming one, the secondary safe distance increases, make the security performance of measuring equipment improve greatly, the secondary cable lead-in wire adopts armouring, guarantee safety, antitheft, cable adopts many colors, makes quick and easy for installationly, prevents mis-wired, guide to the stand below under the ammeter box, conveniently check meter, changing and verification, mainly is that the ammeter box that separates has enough spaces that special junction box is installed, and voltage is separated, circuit closed, could change kilowatt-hour meter by on-load, and the power failure of once needn't operating a switch has ensured the fail safe and the power supply reliability of equipment, also creates conditions for far copying on later on.
