A Hydroelectricity Transformer Having Laminating Structure

The present invention relates to a capacity-separated space-saving faucet-type transformer, and in particular, by installing the transformers used in the faucet in each case, and designing them in a stacked structure, and by connecting each auxiliary transformer through the underground line, The present invention relates to a capacity-separable space-saving faucet transformer characterized by simplicity and minimizing the use of space so that it can be efficiently used in a place where a transformer, such as an apartment or a school hospital.

In general, collective power demand sources such as schools, buildings, apartment complexes, factories, etc., each have a water substation facility to obtain the necessary power.

These substation facilities will include transformers, switches and other safety devices to receive the extra high voltage supplied from the substation and transform it into a suitable low voltage commercial voltage.

1 is a first embodiment of a conventional packaged water substation facility, Figure 2 is a second embodiment of a package water substation of a conventional water substation facility, Figure 3 is an electrical circuit diagram of a conventional water substation device. to be.

As shown, the extra high voltage of three-phase 22,900V input through the high voltage line 2 passes through a failure section automatic section switch (ASS) 4, and then the one side grounded through the high voltage line 6 (8) and the power fuse (10) to be drawn in.

Three power fuses 10 are installed in sets of three RST lines of a three-phase input.

Install the instrument transformer (MOF: Metering Out Fit, 12) in the three-phase line of the extra-high voltage through the power fuse 10 to connect to pick up the voltage and current for measuring the amount of power used,

The voltage and current values detected by the instrument transformer 12 are connected to be applied to a voltmeter and an ammeter installed in the power meter 14.

On the other hand, for each phase, the special high voltage through the power fuse 10 is input to the input terminal of the special high voltage of the △ connection method of the high voltage transformer 18 through the high voltage line 16 to the low voltage terminal of the secondary side with a low voltage of the Y connection method. The low voltage shown on the secondary low voltage terminal of the high voltage transformer 18 is connected to the load 22 through a high speed circuit breaker (MCCB) of 4 terminals.

When the three-phase high voltage up to 22,900V is supplied from the substation to the substation, the high voltage is applied to the high voltage inlet terminal of the fault switchgear with the ASS operating lever along the high voltage line. .

This fault zone automatic switch selects one of the spacing line (or offline) and the extra-high pressure inlet line by the operation of the ASS operating lever.

The extra high pressure line selected by the ASS operating lever is displayed at the high voltage withdrawing terminal of the failure section automatic switchgear, and the extra high pressure is applied to the arrester and the power fuse along the high voltage line.

That is, the fault section automatic switchgear which is arranged in the upper part of the case and forms a stacking structure with the high voltage transformer is configured to supply a high pressure to the high voltage transformer and the current transformer through each of the phase arresters and power fuses of which one side is grounded. Will be authorized.

The power fuse is a silicon fuse filled with an element and silicon anti-corrosion agent in a sealed fuse barrel to generate a very high arc resistance to cut off the fault current in a short time.

However, in the conventional water substation facilities, when the high voltage switch devices and related instruments are arranged around a large transformer whose power consumption is determined as a unit, they have been arranged in a flat manner and safety considerations such as an electric shock accident are considered. As a result, sufficient distances between the devices have been maintained even inside the water substation, so that a large installation area is required to install the water substation, and there is a logistical difficulty in transporting and carrying a large weight of the water substation.

That is, in order to install the conventional power receiving transformer system as shown in FIG. 1, it is necessary to work up a column and raise the transformer, so that a lot of working time is required, in particular, there is a high risk of electric shock accident;

The system as shown in FIG. 2 also occupies a lot of space because the faucet-type transformer system is installed in the horizontal direction, and thus encroaches other spaces, thereby causing a problem that acts as an obstacle during the progress of other processes.

In addition, if the construction by using the system as described above occupy a large area in the construction of the secondary tertiary quaternary transformer, there was a very inefficient use of space utilization.

The present invention is to solve the above problems, and installed in a predetermined number of cases suitable for vertical stacking automatic switchgear and power metering unit and load-side transformers are installed in advance and stacked, multi-connected through the auxiliary transformer and underground cable Therefore, the purpose is to prevent the safety accident by reducing the installation area of the water substation equipment and inserting into the case of the equipment.

An electric base 500;

A high voltage current breaker 600 connected to a secondary side of the meter transformer 520 through a connection line and automatically cut off when an abnormality occurs by embedding an overcurrent relay, an overcurrent ground relay, and an overvoltage ground relay;

A plurality of cut out switches 810 and 810a are connected to the output line of the high voltage current circuit breaker 600 by one set, and heads 820 and 810 are respectively connected to the cut out switches 810 and 810a. 820a) is connected to the power fuse opening and closing base 800 to prevent damage to the transformer due to the flow of overcurrent;

However, as described above, by increasing the number of cut-out switches 810 and heads 820 installed in the power fuse opening and closing base 800, the load-side transformer 900 connected thereto may increase in number. Therefore, various installation conditions can be satisfied.

That is, the present invention is characterized in that the transformer used in the faucet-type transformer system has a configuration to be laminated after each built in the enclosure according to the intended use so that the work is completed by assembly in the field after pre-fabrication in the factory.

Hereinafter, the advantages of the present invention will be described.

As the conventional faucet transformer system is installed after the power pole is set high, the cost of additional restraint increases and the labor cost must be mobilized so that the cost of construction is increased. There are various problems, such as the risk of being lost, but when using the device of the present invention is equipped with a transformer for each case, and then assembled and completed in the field, the work is easily progressed, but risk factors such as falling accidents are eliminated.

In addition, in order to install a conventional faucet-type transformer system, it takes a lot of work time to raise the transformer and work to raise the transformer, but when using the present invention, after the transformer is built in the case in advance, the construction site is completed only by assembly. Because two workers can complete the work in about 4 hours, the work speed is fast and the cost reduction is 20% effective on the cost of existing faucets.

In addition, the use of the present invention prevents the occurrence of algae and baggage drop accidents because the faucet installation is kept in a completely closed state to provide an advantage that can be blocked in advance due to power outages.

As a result, the conventional faucet-type transformer occupies a lot of space at the time of conducting or completing the construction, but the installation cost was not formidable. However, the present invention uses a faucet-type transformer by a lamination method and a capacity division. Installation of the faucet type transformer system was made easy.

In addition, in the conventional faucet facilities, when a bird, such as a magpie, installs twigs to build a house, placing conductive metals may cause an overload due to a short circuit, which may cause an electrostatic accident. If a foreign material infiltrated or a conductive material contained in foreign matter such as yellow dust accumulated in the faucet facility and rained, it could cause a short accident.

However, when the present invention is used, all the faucet facilities are kept in a sealed state inside the case, and thus, it is possible to prevent damage caused by algae, and also to prevent damage caused by foreign substances in the air. It will be provided.

In addition, since the present invention is easy to install as well as easy to dismantle, it is possible to withdraw the work using a small number of workers within a short time, thereby satisfying the quick installation and the quick dismantling work at the same time.

In addition, since the present invention is stacked in a case shape to minimize the area to minimize the impact on other construction, in particular, the conventional switchgear transformer, instrument transformer and load-side transformer, which is essential for the faucet installation, is arranged on a plane Because it takes up a lot of space, but if stacked vertically as in the present invention occupies a small area that is very advantageous for space use.

This may not cause a big problem even if the land is stretched to a flat surface in a wide country like the United States, but if a long stretch to a flat land in a narrow country like Korea may cause problems in space utilization, as in the present invention. If each transformer is mounted in a case and raised vertically, it will naturally optimize space utilization.

When the present invention is configured as described above, it can be easily used in a power receiving transformer used for a capacity of 1000 KVA or more.

After all, the present invention is to install the transformers used in the faucet in each case and to design them in a laminated structure, the ease of installation as well as the use of space is reduced to a minimum, especially when applied to large constructions, such as apartment construction site efficiently It includes ancillary advantages that make it available and does not interfere with other construction.

Hereinafter, the effects of the present invention will be described in more detail.

Conventionally, it is designed to flow from low voltage or high pressure 3300V in the central substation type, and the construction cost is enormous because the 2nd, 3rd and 4th substations are required, and the power loss leads to no-load loss of the line loss transformer. Bar, based on the transformer capacity of 2000KVA, there is a loss of about 45KW of load power loss, which is more than 1000SQ of standard wire and 100M of line, and it is 34,560KWH loss when it is calculated as one month, which is 200 won per KWH Even if the calculation is made, the loss is 34,560KWH * 200 won = 6,912,000 won.

Since a line of about 300-400M is normally required, 3-4 times of the loss is generated.

And, if the transformer no-load loss is calculated, the loss of the transformer capacity of 2000KVA is about 20KW, 14,400KWH per month, and 14,400KWH * 200 Yuan = 2,880,000 is additionally generated.

However, when the present invention is used, the central substation chamber has no load loss because the transformer is installed in a small capacity, and almost no power loss occurs, and since the switchboard is attached together in the transformer chamber itself, there is no need for a separate switchboard. .

And, it is safe because the high pressure goes underground, and the transformer is sealed and there is an effect that everyone is safe.

In addition, the installation area of the transformer capacity 2000KVA shows that the power supply facility area flows from 100 pyeong to 150 pyeong and high pressure 3300 V. Low voltage substation room 100-150 pyeong Secondary substation room 100 pyeong However, when the present invention is used, since the primary substation chamber is 2.5M * 2.5M, it occupies about 2 pyeong, and the secondary tertiary quaternary quadratic occupies the same area, which is much more advantageous in terms of area. Since the invention occupies little space for the faucet-type power generation facilities as described above, almost no civil work is required, and the wire material is also 1000SQ in the past, but in the present invention, the thin line is about 60SQ, and the power consumption is greatly reduced. Since the cost of power receiving facility construction is reduced to about one-third, the construction of the power receiving facility of the present invention is possible even with the civil engineering cost of the conventional power receiving facility. It is able to enjoy the economic benefits.

And although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications or variations without departing from the spirit and scope of the invention.

Accordingly, the appended claims will include such modifications and variations as fall within the spirit of the invention.
