Abstract

The utility model belongs to the technical field of transformers, and particularly relates to an anti-electricity-theft combined transformer. The anti-electricity-theft combined transformer is characterized in that a current transformer, a primary conductive bar, a primary conductive pole, a voltage acquisition terminal, a secondary current acquisition terminal and a thief-proof transparent cover are included; and a hole penetrated by a secondary control cable and a square groove penetrated by a parallel cable are formed on a transformer casing. The secondary terminal of the transformer and a secondary conductive pole of the transformer are sealed, thereby avoiding theft of electricity from the secondary terminal of the transformer and the secondary conductive pole of the transformer, and achieving meterage through a single meter for two parallel transformers.

Description

Anti-electricity-theft combination transformer

Technical field

The utility model belongs to the instrument transformer technical field, is specifically related to a kind of anti-electricity-theft combination transformer.

Background technology

The low-temperature measurement device is made up of electric energy meter, instrument transformer and secondary control cable at present, because of the secondary conducting rod of the secondary terminal of instrument transformer and transformer mostly exposed outside or part exposed outside, this situation is easy to implement stealing on the secondary conducting rod of the secondary terminal of instrument transformer and transformer.Correct in addition voltage signal reliably is the necessary condition of electric energy meter operate as normal, and existing product exists or be unreliable, or does not seal.

Also have a kind of situation to be, existing instrument transformer can only measure single transformer, can't measure two shunt transformer list tables.

Summary of the invention

The utility model aims to provide a kind of combination transformer that prevents stealing on instrument transformer secondary terminal and the transformer secondary conducting rod, and can realize that two shunt transformer list tables measure.This instrument transformer has the function of current transformer, can gather the required voltage signal of electric energy meter reliably again, again the transformer secondary conducting rod is sealed simultaneously.

The following technical scheme of the concrete employing of the utility model:

A kind of anti-electricity-theft combination transformer, it is characterized in that, comprise current transformer, primary conductive row, primary conductive bar, voltage acquisition terminal, secondary current collection terminal, thief-proof translucent cover, the instrument transformer housing is provided with a hole that penetrates for the secondary control cable and the square groove that penetrates for shunt cable, and first and second loads onto antitheft translucent cover and lead sealing after carefully connecting the wire.

The utility model has the advantages that: the utility model is the sealing of instrument transformer secondary terminal and transformer secondary conducting rod, can prevent stealing on instrument transformer secondary terminal and the transformer secondary conducting rod, and can realize that two shunt transformer list tables measure.

Embodiment

Embodiment 1: single transformer

As shown in Figure 1, 2, 3, anti-electricity-theft combination transformer, comprise current transformer 1, primary conductive row 7, primary conductive bar 3, voltage acquisition terminal 11, secondary current collection terminal 10, thief-proof translucent cover 9, thief-proof translucent cover 9 is with transformer secondary conducting rod 8, primary conductive bar 3,11 sealings of voltage acquisition terminal, and thief-proof translucent cover 9 is fixed on the utility model product shell by anti-theft screw 10.When anti-electricity-theft combination transformer is installed on the single transformer, and adopt cushion block 5 that product is fastening, and product is assemblied on the transformer secondary conducting rod 8 then, again secondary control cable 4 is passed from hole 12, connect electric current and pressure-wire by sign, at last thief-proof translucent cover 9 is loaded onto and lead sealing.

2: two transformers connected in parallel of embodiment

Shown in Fig. 4,5,6, the situation when being installed in two transformers connected in parallel operations for the utility model.Cushion block 5 is removed from the product square groove.On the secondary conducting rod of elder generation with another transformer of packing into of shunt transformer cable 14, refill product of the present utility model then.Secondary control cable 4 is passed from hole 12, connects electric current and pressure-wire by sign, at last antitheft translucent cover is loaded onto and lead sealing.All the other are substantially the same manner as Example 1.

Claims (1)

1. anti-electricity-theft combination transformer, it is characterized in that, comprise that current transformer, primary conductive row, primary conductive bar, voltage acquisition terminal, secondary current gather terminal, thief-proof translucent cover, the instrument transformer housing is provided with a hole that penetrates for the secondary control cable and the square groove that penetrates for shunt cable.
