Background technology
Electric power meter is what a key equipment of power supply department metering electric energy; Be to supply electricity consumption both sides e-trade to be prone to the foundation of clearing; Whether its metering result is reliable, accurate, true, and whether be directly connected to both sides' trade settlement fair, fair and rational, is directly connected to both sides' interests; Therefore the charge electric energy metering device is especially carried out the technical equipment transformation to the large electricity consumer, the accuracy that promotes its metering is the major issue that relation supplies the electricity consumption both sides.
Particularly under the condition that is becoming tight supply of electric power day; If the low-voltage power metering device is defectiveness in design; The possibility of stealing is provided for illegal user, causes serious power loss, so the power supply department requirement is more urgent to the transformation of the anti-electricity-theft metering device of low pressure.
Power supply department adopt in low-voltage supply line hanged down the modes that supply low meter more at present, and stoichiometric point is located at transformer secondary terminal place.Existing Circuit Fault on Secondary Transformer metering instrument transformer does not possess anti-electricity-theft function, and metering instrument transformer structure is single, can not satisfy the requirement of field erected flexibility and complexity, and the metering instrument transformer is not only during installation fee and effort, and the installation difficulty increasing.
The utility model content:
For overcoming the defective of prior art, the purpose of the utility model be to provide a kind of Mechanical Builds simple, be prone to installation and maintenance, have the anti-electricity-theft combination transformer of low pressure of anti-stealing electricity function.
The utility model technical solution problem adopts following technical scheme:
The anti-electricity-theft combination transformer of low pressure; Comprise the instrument transformer housing, be located at the iron core in the instrument transformer housing and be wound on the secondary coil on the iron core; Side at the instrument transformer housing is provided with transformer secondary binding post installing hole, and the top of secondary connection post installing hole is provided with primary conductive row, and the transformer secondary binding post passes through primary conductive row and is connected with it; Primary conductive row passes transformer iron core; Draw from the top of instrument transformer housing, the once thief-proof translucent cover of instrument transformer is set above transformer secondary binding post installing hole, and be installed on the instrument transformer housing through thief-proof lead sealing screw; Opposite side at the instrument transformer housing is provided with instrument transformer secondary installing hole; The thief-proof translucent cover of instrument transformer secondary is installed in side, instrument transformer secondary installing hole, and is installed on the instrument transformer housing through thief-proof lead sealing screw, and the below in instrument transformer secondary installing hole is provided with instrument transformer secondary control cable wire hole.
Further, once thief-proof translucent cover of instrument transformer and the thief-proof translucent cover of instrument transformer secondary adopt transparent electrically non-conductive material, can know and see the back panel wiring situation.
Further, described iron core is a ring-shaped core.
The beneficial effect of the utility model:
To present power supply department modes that adopt the low meter of low confession in low-voltage supply line more; Stoichiometric point is located at the characteristics at transformer secondary terminal place; New design has been taked reliable seal approach to first and second binding post of instrument transformer, prevents once to shunt stealing through short circuit; Designed the secondary terminal board, the secondary lead is totally-enclosed, prevents through the secondary stealing.
Side at the instrument transformer housing is provided with transformer secondary binding post installing hole; Can instrument transformer directly be set on the transformer secondary binding post, needn't consider the situation different in size of transformer secondary binding post, practice thrift cost; Save the space, and installation is oversimplified.
No matter three or four instrument transformers (considering zero phase) all can move separately, adjustable positions is supporting with the spacing of transformer secondary binding post, makes the electricity anti-stealing wiring box standardization of instrument transformer.

Embodiment
Fig. 1 is the structural representation of an embodiment of the utility model instrument transformer; It has only a current transformer winding; Because different occasions, different metering device, use the current transformer of varying number, only need situation at the scene according to the scene; The instrument transformer that varying number is installed gets final product, and this also is a reason of being called combination transformer.
The anti-electricity-theft combination transformer of low pressure in the present embodiment; Side at instrument transformer housing 1 is provided with transformer secondary binding post installing hole 2; Transformer secondary binding post 9 is drawn from transformer secondary insulator 10, and the top of transformer secondary binding post installing hole 2 is provided with primary conductive row 3, and transformer secondary binding post 9 passes through primary conductive row 3 and is connected with it; Primary conductive row 3 passes transformer iron core, draws from the top of instrument transformer housing 1.The primary conductive row 3 who draws from the top of instrument transformer housing 1 is connected with subscriber cable 11.
The once thief-proof translucent cover 4 of instrument transformer is set above transformer secondary binding post installing hole 2, and is installed on the instrument transformer housing 1 through thief-proof lead sealing screw 5.Opposite side at instrument transformer housing 1 is provided with instrument transformer secondary installing hole 7, and the thief-proof translucent cover 6 of instrument transformer secondary is installed in 7 sides, instrument transformer secondary installing hole, and is installed on the instrument transformer housing 1 through thief-proof lead sealing screw 5.The below in instrument transformer secondary installing hole 7 is provided with instrument transformer secondary control cable wire hole 8, and instrument transformer secondary control cable 13 is connected in instrument transformer secondary connection post 12, and from instrument transformer secondary cable wire hole 8, draws.
