Technical field
The utility model relates to the electrical installation that uses in the transmission line, particularly relates to a kind of anti-electricity-theft combination transformer.
Background technology
Present employed electricity distributing and metering device is many to be made up of metering electric energy meter and instrument transformer, because of the binding post of instrument transformer all exposes outside measuring equipment, in case between binding post bonding conductor, electric energy meter just can not accurately be worked, so the people happens occasionally for stealing.The electricity filching person that has adopts hidden gimmicks such as iron filings connect, and influences the correct metering of electric energy meter, when checking the electric meter, vibrations is arranged slightly, and the iron filings that connect can disappear, so be difficult to find.
The utility model content
Based on above-mentioned existing in prior technology problem, the utility model embodiment provides a kind of anti-electricity-theft combination transformer, makes the instrument transformer binding post not exposed, avoids carrying out stealing at electricity filching person bonding conductor between binding post.
The utility model is achieved through the following technical solutions:
The utility model embodiment provides a kind of anti-electricity-theft combination transformer, comprising:
Many voltage transformers, primary connection terminal, shell and terminations;
Many voltage transformers all are provided with in the enclosure, form a voltage transformer and a current transformer after many voltage transformers are electrically connected respectively, a winding lead-out wire of voltage transformer and current transformer is electrically connected with the primary connection terminal that is arranged on the housing respectively; The secondary winding lead-out wire of voltage transformer and current transformer is electrically connected with each binding post that is arranged on the termination in the housing respectively, is provided with aperture at shell and termination corresponding position, and the connection lead-out wire of termination is drawn by aperture.
By above-mentioned embodiment of the present utility model as can be seen, in the utility model embodiment, be located in the shell by termination owing to this combination transformer, can't will carry out short circuit between the binding post of termination from the outside, thereby use this combination transformer can effectively prevent stealing.

When using, the combination transformer that Fig. 2 provides for the utility model embodiment is electrically connected schematic diagram;
Each label is among the figure:
1. shell; 2. secondary enclosing; 3. primary connection terminal.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment
Embodiment
Present embodiment provides a kind of anti-electricity-theft combination transformer, can be used in the power circuit to use as electric energy measurement equipment, and be the combination transformer that a kind of voltage transformer and current transformer all are set together, as shown in Figure 1, 2, this combination transformer comprises:
Many voltage transformers all are provided with in the enclosure, after being electrically connected, many voltage transformers form a voltage transformer and a current transformer respectively, specifically be made up of six instrument transformers, wherein three instrument transformers are connected to become voltage transformer, can be used in the three phase line; Other three are connected to become current transformer (the concrete connection mode between each instrument transformer can with reference to Fig. 2); A winding lead-out wire of voltage transformer and current transformer is electrically connected with the primary connection terminal 3 that is arranged on the housing respectively; The secondary winding lead-out wire of voltage transformer and current transformer is electrically connected with each binding post that is arranged on the termination in the housing respectively, be provided with aperture at shell and termination corresponding position, the connection lead-out wire of termination is drawn by aperture, and the connecting line of drawing from the shell aperture can be for having the lead of insulation wrapping.
The termination place of corresponding enclosure is provided with secondary enclosing in the combinations thereof instrument transformer, and secondary enclosing is fixed on the shell by lead protection sealing nail, and termination is enclosed in the shell; Also be provided with loosing-proof device on described secondary enclosing, by loosing-proof device secondary enclosing be fixed on the shell, fixedly the connecting line of the lead protection sealing nail of secondary enclosing penetrates from described loosing-proof device.Loosing-proof device is generally four.
Be described further below in conjunction with Fig. 1,2 pairs of combinations thereof instrument transformers:
This anti-electricity-theft combination transformer is formed by connecting by many instrument transformers, the lead-out wire of each instrument transformer is connected with termination, instrument transformer and termination all are provided with in the enclosure, have aperture at the shell line position place that connects, draw the lead that having the insulation wrapping output line by aperture in the case body as instrument transformer.
In this anti-electricity-theft combination transformer, 1 corresponding inner termination place is provided with secondary enclosing 2 at shell, secondary enclosing is fixed on the shell by lead protection sealing nail, can be easily the termination of enclosure interior be carried out processing such as wiring by opening secondary enclosing, open secondary enclosing short circuit back panel wiring device easily for preventing electricity filching person, loosing-proof device is set on secondary enclosing, this loosing-proof device specifically is four jockeys that are provided with on secondary enclosing, penetrate in four jockeys of the connecting line of lead protection sealing nail, add at last and be honored as a queen, if secondary enclosing is opened, then connecting line damages automatically, can confirm that secondary enclosing took apart, thereby confirm that the user has carried out stealing.
Bottom at the combinations thereof instrument transformer can be provided with damping resistance, can effectively prevent voltage three-phase imbalance problem.
In sum, the combination transformer among the utility model embodiment is located at the termination of instrument transformer in the case body, is difficult to short circuit between the termination, thereby can well prevents stealing.
The above; it only is the preferable embodiment of the utility model; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range of claims.
