technical field

The utility model relates to electrical equipment, in particular to a wind power substation.

Background technique

Substation, a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation.

In the prior art, a Chinese patent discloses a box-type substation with the publication number CN101640386A. The device includes a high-voltage chamber, a voltage-transforming chamber and a low-voltage chamber. In the type substation, the high-voltage room and the low-voltage room are closed structures, and the transformer room is a semi-closed corridor structure. Although the device realizes the separation of the transformer chamber from the low-voltage chamber and the high-voltage chamber, avoids the pollution in the transformer oil tank, and is beneficial to the heat dissipation of the transformer. However, the device still has the following problems: 1) Since the transformer in the transformer chamber must be connected to the circuit breaker in the low-voltage chamber, and the low-voltage chamber of the device is a closed structure, and the transformer chamber is a semi-closed gallery structure, it cannot The connection between the transformer and the circuit breaker is realized when the above conditions are met; 2) When the transformer needs to be repaired, etc., it is inconvenient to disassemble between the transformer chamber and the high-voltage chamber and low-voltage chamber.

The pressing block of the first spring, the pressing block is used to connect the second joint piece when the terminal is inserted into the socket. When the terminal is inserted into the jack, the terminal is pressed against the pressing block, the first spring is compressed, and under the restoring force of the first spring, the pressing block presses the second joint, thereby preventing the terminal from contacting the second joint. Poor contact between sheets.

In order to prevent the binding posts from slipping out of the socket of the terminal block arbitrarily, and to realize the detachment of the clamping posts from the terminal posts when the binding posts are pulled out, preferably, a clamping post is provided in the socket of the terminal block, The clamping column is located on the side of the copper sheet facing away from the first spring. A telescopic hole for the clamping column to expand and contract is opened in the terminal block. A second spring is connected between the clamping column and the bottom surface of the telescopic hole. The clamping column is used to insert The terminal in the jack is stuck; the clamping post is a cylindrical structure, and the end of the clamping post that is clamped with the terminal is a hemispherical structure, so that the terminal can be connected with the clamping post when the transformer chamber is pulled away from the low-voltage chamber. Column detached.

Compared with the prior art, the utility model has the following beneficial effects:

1) The connection between the transformer and the circuit breaker is realized under the condition that the high-voltage room, the transformer room and the low-voltage room are arranged in the shape of "pin" in the box-type substation;

2) While realizing the connection between the transformer and the circuit breaker, the structure is simple and easy to use.
