[0001] The utility model relates to the technical field of two-location high-voltage incoming lines, in particular to a two-location high-voltage incoming line device for a steelmaking high-voltage distribution room. Background Art
[0002] With the development of society, the value generated by the steelmaking industry is getting bigger and bigger, and steelmaking is becoming more and more important. When steelmaking is carried out, power is usually supplied through a special high-voltage distribution room. In order to ensure the normal power supply of the distribution room, two distribution rooms are usually set up to work together to avoid failures in the distribution room, which will cause the steel mill to be in a power outage for a long time and make the steel mill unable to operate.
[0003] However, there is no connection between the existing distribution rooms in steel mills. Therefore, when a distribution room fails, the steel mill will suddenly lose power for a period of time until another distribution room starts working. The steel mill can then return to normal operation, but there will still be transmission interruptions, so there are certain limitations. Utility Model Content

The gates are electrically connected to the high-voltage cable, and when the gates are closed, current will pass through the high-voltage cable.
[0008] Preferably, the bottom of the bottom shell is fixedly connected with pillars, and the pillars are distributed on the left and right sides of the bottom of the bottom shell. The bottom ends of the two pillars are respectively fixedly connected to the outer wall of distribution room one and the outer wall of distribution room two, and the bottom shell is fixed to the outer wall of distribution room one and the outer wall of distribution room two through the pillars.
[0009] Preferably, the top of the bottom shell abuts against the bottom of the top shell, and the bottom shell can limit the top shell. The card is engaged with the groove, and the top shell can be moved so that the card is inserted into the groove, thereby limiting the top shell.
[0010] Preferably, the limiting rings are distributed on the left and right sides of the bottom of the bottom shell and the left and right sides of the top of the top shell.

The support is distributed on the left and right sides of the bottom of the bottom shell 501. The bottom ends of the two supports are respectively fixedly connected to the outer wall of the distribution room 1 and the outer wall of the distribution room 2. The bottom shell 501 is fixed to the outer wall of the distribution room 1 and the outer wall of the distribution room 2 by the support. The top shell 502 is installed on the back of the distribution room 1. The top of the bottom shell 501 is connected to the top shell 5 02, the bottom shell 501 can limit the top shell 502, the groove 503 is opened at the inner top of the bottom shell 501, the clamping plate 504 is fixedly connected to the bottom of the top shell 502, the clamping plate 504 is clamped with the groove 503, and the top shell 502 can be moved so that the clamping plate 504 is clamped into the inside of the groove 503, thereby completing the limit of the top shell 502, the limiting ring 505 is fixedly connected to the bottom of the bottom shell 501, and the limiting ring 505 is distributed on the left and right sides of the bottom of the bottom shell 501 and the left and right sides of the top of the top shell 502, and the annular buckle 506 is installed The outer wall of the annular buckle 506 is slidably connected to the inner wall of the limiting ring 505 on the outer wall of the bottom shell 501.
