Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transformer case, in which a transformer for converting an input voltage into another output voltage and outputting the transformed output is housed.
Transformers, such as transmission ground transformers and distribution ground transformers, are generally bulky and generate a lot of heat during transmission and distribution. Accordingly, a cooling fin is formed around the transformer case, and the cooling oil flows into the inside of the transformer case, thereby quickly discharging the heat generated by the ground-type transformer.
Thus, the transformer includes a plurality of winding coils having mutual induction, an iron core wound with the winding coils to form a magnetic force, and a bushing for pulling out the terminals of the winding coils to the outside. The transformer is usually provided on an electric pole, So that it can transform and distribute it. Such a transformer is provided with a cylindrical case filled with insulating oil to cool the coil, the iron core, and the bushing while the transformed voltage is supplied and distributed.
However, in the conventional transformer case, a voltage indicator and a breaker are provided on the front plate, and an input terminal port and an output terminal port are provided on the rear plate. Therefore, it is troublesome for the operator to check the presence or absence of abnormality by connecting the input terminal and the output terminal to the input terminal port and the output terminal port of the rear plate respectively, and then come back and look at the voltage indicator on the front plate.
Also, since the input terminal port and the output terminal port are at an angle of 90 °, there is a problem that the wire connection is difficult and the bending of the wire is out of the allowable range. In addition, there is a problem that the top plate, the side plate, and the back plate must be unlocked to confirm the inside of the transformer. Also, since the inside of the transformer is dark, it is difficult to check the inside of the transformer. Further, there is a problem that heat is not discharged well because no separate ventilation hole or ventilation fan is formed. Also, since the voltage indicator is protruded on the front panel, it may be caught by other objects during transportation and be damaged.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a transformer case capable of easily discharging internal transformer heat. Another object of the present invention is to connect a power input line and a power output line to a transformer case without bending. The present invention also provides a switching means for allowing the outside and inside of the transformer case to be viewed even in a dark place, and also provides a photographing control means according to a switching operation. The technical problem of the present invention is to facilitate the transportation of the transformer case.
An embodiment of the present invention is a method of manufacturing a semiconductor device, comprising: a tubular inner space having a front plate on which an opening is formed, a rear plate facing the front plate, one side plate connecting the front plate and the rear plate, Wherein at least one of the front plate, the rear plate, the one side plate, the other side plate, and the bottom plate has a ventilation hole and an opening is formed on the upper side of the inner space; An upper plate for opening and closing an opening of the housing; A voltage indicator provided on the front plate for displaying a voltage; An input terminal port provided with a plurality of input terminals to which power input lines are connected; An output terminal port provided with a plurality of output terminals to which power output lines are connected; And a terminal block provided with the input terminal port and the output terminal port and having an acute angle slope inclined with respect to the bottom plate by 90 ° from the opening of the housing to the inner space of the housing.
The transformer case may include a terminal block angle variable member for varying the inclination of the terminal block so that an angle between the terminal block and the bottom plate is varied.
The upper plate may be hinged to the housing and may be opened or closed through an opening of the housing by hinge rotation or may be opened or closed by a sliding door.
The transformer case may include a breaker provided on the front plate and capable of blocking electric power supplied from the power input line from being transmitted to the winding coil.
And a front panel protection guide panel having a square frame structure protruding from the edge of the front panel.
The transformer case includes a voltage indicator lamp capable of providing illumination to the voltage indicator; A terminal port lamp provided on the inner surface of the front plate for providing illumination to the input terminal port and the output terminal port; And an inner lamp provided on an inner surface of at least one of the front plate, the rear plate, the one side plate, and the other side plate to illuminate the inner space of the housing.
The transformer case may include a lamp switch receiving the switching input of the voltage indicator lamp, the terminal port lamp, and the internal lamp.
The lamp switch is implemented as a three-stage toggle switch, and turns on only one of the voltage indicator lamp, the terminal port lamp, and the internal lamp, and turns off the other remaining lamps. have.
Wherein the transformer case includes a camera assigned to each of the voltage indicator lamp, the terminal port lamp, and the internal lamp, wherein the voltage indicator lamp, the terminal port lamp, The camera is turned on to transmit the image to the central server, and the camera assigned to the lamp operated off from the voltage indicator lamp, the terminal port lamp, and the internal lamp is turned off. have.
The transformer case may include a ventilation fan provided on one of the one side plate, the other side plate, and the rear plate.
According to the embodiment of the present invention, since the voltage indicator, the input terminal port, and the output terminal port are provided on the front plate of the transformer, it is possible to check whether there is an abnormality immediately after connecting the input and output, And it is possible to reduce the inconvenience of confirming the abnormality by coming forward.
In addition, the present invention minimizes the bending of the wire when the input terminal port and the output terminal port are tilted by 45 degrees and is different from the conventional transformer case which is inclined by 90 degrees. It is easy to see and connect.
Further, according to the present invention, a lamp is mounted on the upper part of the input terminal port, the output terminal port, and the voltage indicator, so that it is possible to check whether there is an abnormality in a dark place or at night. In addition, the top of the case can be opened to facilitate tab switching, cleaning and heat discharge. The transformer case is also equipped with a lamp so that it can be clearly seen when switching the tap or checking for abnormality. Also, you can turn on the lamp and turn on the inside and the terminal side by putting three cascade switches on the battlefield, and you can turn it off when not needed.
Further, in the present invention, a voltage indicator or the like provided on the front plate may go inward to protect deposits during falling or packaging.
In addition, there is a disadvantage in that heat is often generated due to the characteristics of a transformer. In the present invention, four sides are a ventilation hole, and hot air rises upwardly. Thus, when the upper opening is opened, five sides can be realized as ventilation holes. Heat can be captured efficiently.
