Description

High Voltage Transformer for Substations in Substations

The present invention relates to an extra high voltage transformer for a substation.

In general, in recent years, underground laying method is widely used to bury the power cable in the ground to prevent exposure to the outside.

This underground laying method is to supply the high-voltage electricity through the underground wires buried underground, using the ground-mounted transformer unit (2) connected to this power cable to reduce the voltage and then supply electricity to the general consumer.

The transformer unit 2 is installed in a protective enclosure installed on the ground, as shown in Figure 1, the outer side is provided with a connector (3) to which the underground wire (4) is connected.

At this time, an end portion of the underground wire 4 is provided with a T-shaped connection terminal A, and the voltage drop is reduced by the transformer unit 2 by connecting the connection terminal A to the connector 3. Electricity can be supplied to the general consumer via the underground cable 4.

In order to prevent this, conventionally, the frequency of the band hated by the rat was transmitted around the electric unit to prevent the rat's access to the electric unit, but this also was not effective, and the rat's hearing was simultaneously stimulated simultaneously with the hearing to the electric unit. The need to prevent rats' access was raised.

In addition, the insulating oil is filled in the transformer unit 2 to prevent discharge between windings.

However, in the live state in which power is applied to the transformer unit 2, if bubbles are generated in the insulating oil or the level of the insulating oil is lowered, the insulating oil loses the insulation function, and thus, the transformer unit 2 Is damaged or severe, the temperature of the insulating oil is sharply increased, the transformer unit 2 is exploded.

Therefore, when an earthquake occurs, the entire transformer unit 2 is shaken to shake the insulating oil. As a result, bubbles are generated in the insulating oil and insulation breakdown occurs. Thus, the transformer unit 2 is damaged or exploded. There was a problem that caused damage around.

The opening 74 may be closed by rotating the 72 or the lower block 71. Therefore, the fixing block 70 is coupled to the outside of the support rod 62 so that the upper and lower surfaces of the fixing block 70 are interposed between the lower surface of the terminal case 20 and the upper surface of the weight 63, and thus the weight 63. And the support rod 62 can be fixed so as not to move.

The alarm mechanism 200 is horizontal to the alarm mechanism body 210 installed on the inner wall of the protective housing 5, the sound plate 220 in the notification mechanism body 210, and the alarm mechanism body 210 The piston 230 is installed to be movable, and the alarm mechanism spring 240 inherent in the alarm mechanism body 210.

The alarm mechanism body 210 has a cylindrical shape having a space therein, one end of which is fixed to the inner wall of the protective housing 5 and the other end thereof protrudes perpendicular to the underground wire 4. At this time, the lower portion of the alarm mechanism body 210 is formed with a through hole 211 for the release of aversion sound.

The sound plate 220 is a plate-shaped metal body having a predetermined hardness, and is installed on the ceiling wall of the alarm mechanism body 210. At this time, in order to generate a more disgusting sound may be formed irregularities on the outer surface of the sound plate 220.

The piston 230 includes a tip portion 231 inserted into the alarm mechanism body 210 and a fixed portion 232 exposed to the outside of the alarm mechanism body 210 and fixed to the underground wire 4. Then, the alarm mechanism body 210 is installed to be movable horizontally.

The tip portion 231 has a predetermined hardness and is pointed upward to contact the sound plate 220.

The alarm mechanism spring 240, one end is fixed to the inner wall of the alarm mechanism body 210 and the other end is fixed to the end of the piston 230, and supports the piston 230 in a shot.

On the other hand, the hardness of the sound plate 220 and the tip portion 231 can be adjusted as needed to produce the desired disgusting sound.

In addition, a display band 300 is attached to the periphery of the tip end portion of the underground wire 4. As shown in FIG. 5, the display band 300 has a color different from that of the outer sheath 4b of the underground wire 4 and is circumferentially bonded to the outer surface of the sheath 4b. When the underground wires 4 are raised together, they are inserted into the extension pipe 22 and are hidden. When the underground wires 4 are lowered together with the slider 30, the underground wires 4 are exposed to the lower part of the extension pipes 22 and the slider ( 30) and the underground wire (4) is to be confirmed by the operator with the naked eye.

The movement sensor 400 is installed on the inner side of the alarm mechanism body 210 to detect the movement of the piston (230). Here, the movement detection sensor 400 is a conventional ultrasonic sensor or infrared sensor, detailed description thereof will be omitted. On the other hand, the reflection panel (P) is installed at the end of the piston 230 inserted into the alarm mechanism body 210 so that the movement detection sensor 400 can more accurately detect the movement of the piston 230.

The light emitting unit 500 is installed in the terminal case 20 to prevent the rat from approaching the transformer unit 2 by riding the underground wires 4 by emitting intense light.

The control unit 600 is built in the protective enclosure (5), and controls the movement detection sensor 400 and the light emitting unit (500).

At this time, the control unit 600 blinks the light emitting unit 500 in accordance with the output signal from the movement detection sensor (400). That is, the control unit 600 blinks the light emitting unit 500 when receiving the movement signal indicating that the piston 230 has moved from the movement detecting sensor 400, and turns off the light emitting unit 500 when the movement signal is not received.

Referring to the operation of the special high voltage transformer of the substation configured as described above are as follows.

First, the operator holds the terminal case 20 by hand while the fixing block 70 is fitted to the support rod 62, and the electrode member 10 is connected to the connector 3 of the transformer unit 2. Can be combined. In this case, the underground wire 4 is provided with a display band 300, and when the display band 300 is not visible, the underground wire 4 and the slider 30 are lifted up to be connected to the electrode member 10. When the display band 300 is visible to the naked eye, it means that the locking mechanism 50 is released and the underground wire 4 and the slider 30 are lowered to cut off the electrical connection. Therefore, when the operator visually observes the underground wires 4 so that the display band 300 is visible, the upper surface of the slider 30 is connected to the electrode member 10 by pushing the underground wires 4 upwards. In this case, the ratchet bolt 51 of the fixing mechanism 50 is advanced to be caught by the latching jaw 32 of the slider 30 so that the slider 30 is not lowered.

And, in the state in which the electrode member 10 is connected to the connector 3, the operator can complete the installation of the connection member 100 by removing the fixing block 70.

Thereafter, the worker installs the alarm mechanism 200 on the inner wall of the protective enclosure 5, and fixes the piston fixing portion 232 of the alarm mechanism 200 to the underground wire (4). At this time, the movement detection sensor 400 is installed in the alarm mechanism body 210, the light emitting unit 500 is installed in the terminal case 20, and the control unit 600 is installed in the protective enclosure 5. .

In the state where the substation special high voltage transformer is installed as described above, when the rat rides up the underground wire 4 and the underground wire 4 swings from side to side, the piston 230 swings from side to side as shown in FIG.

When the piston 230 is shaken, the movement detection sensor 400 detects the movement of the piston 230 and outputs a movement signal, and the control unit 600 which receives it flashes the light emitting unit 500.

At this time, the light emitting unit 500 emits light downward toward the underground wires 4, and the mouse cannot move upward along the underground wires 4 due to the strong light.

On the other hand, when the piston 230 is shaken, the tip portion 231a of the piston 230 makes a disgusting sound while scratching the sound plate 220. At this time, the alarm mechanism spring 240 provides a repulsive force to the piston 230 so that the piston 230 easily shakes from side to side, so that the aversion sound is further increased. As a result, the rat is not surprised by the disgusting sound and cannot approach the transformer unit 2 along the underground wires 4.

In addition, as described above, when the special high-voltage transformer for substation of the substation is installed, when the protective enclosure vibrates due to an earthquake, a reaction force is generated and the weight 63 vibrates, and thus, shown in FIG. 7. As described above, the fixing rod 50 is released by pulling back the ratchet bolt 51 by pulling the connecting wire 61 while the supporting rod 62 is rotated. Then, as the fixing mechanism 50 is released, the slider 30 is pushed downward by the spring 40, and the connection between the slider 30 and the electrode member 10 is released, whereby the slider 30 is released. ) Is disconnected from the electrode member 10 to cut off the power applied to the transformer unit 2.

The high voltage transformer for substation of the substation configured as above emits intense light to the rats coming up the underground wires (4) and at the same time emits disgusting sound to prevent the rats from accessing the transformer unit (2), thereby damaging the transformers by the mice. Can be prevented.

In addition, when the transformer unit 2 is shaken due to an earthquake or the like, the fixing of the slider 30 is released to automatically cut off the power applied to the transformer unit 2, and thus the transformer unit 2 having insulation breakdown occurs. The power is continuously applied to the transformer unit 2 is damaged or exploded, there is an advantage that can prevent damage to the surroundings.

In particular, since the weight device 63 is vibrated by the vibration applied to the transformer, there is an advantage of high reliability.

Furthermore, the support rod 62 is provided with a support ball 62 provided in the middle portion, and pulls the connecting wire 61 while being rotated in a free direction, so that vibration occurs in any direction regardless of the direction of the vibration. Even if it has the advantage of releasing the fixing of the fixing mechanism 50 by pulling the connection wire (61).

In addition, since the fixing block 70 coupled to the support rod 62 is provided to prevent the support rod 62 and the weight 63 from being rotated, the support rod 62 is not intended by the operator. Is rotated there is an advantage that can be prevented that the fixing of the fixing mechanism 50 is released.

In addition, the display band 300 is attached to the front end portion of the underground wires 4, and when the underground wires 4 and the slider 30 are lowered and the electrical connection is cut off, the operator can easily check with the naked eye. have.
