Description

A phase-shifting transformer connection box

Field

The invention relates to the technical field of transformers, in particular to a transformer connection box.

Background technique

By adjusting the phase difference between input and output voltages, phase-shifting transformers can realize the adjustment of power flow distribution between parallel transmission lines and large independent power grids, and improve the operation stability and efficiency of power systems. Usually, a phase-shifting transformer consists of two independent bodies, which are respectively placed in different oil tanks. The two bodies are connected to each other across the oil tanks. The connection structure is complicated and the installation is difficult.

Contents of the invention

In view of the above problems, the present invention provides a phase-shifting transformer connection box.

In order to solve the above problems, the technical solution adopted by the present invention is: a phase-shifting transformer communication box, including a box body for connecting the oil tanks on both sides, the lower side wall of the box body is provided with a lower opening, and the upper side wall is provided with a There is an upper opening, and the inner side wall of the box body is welded with an internal bracket; the two ends of the box body are connected to the fuel tanks on both sides through flanges; the outer side wall of the box body is provided with reinforcing iron and the lower side wall of the box body is provided with The support bases connected to the fuel tanks on both sides are connected with a screw rod that can move the box body up and down between the support bases and the box body.

The lower opening on the lower side wall of the box body can be used by the staff to pass through. After the Unicom box is installed, the staff can enter the interior of the Unicom box through the lower opening and place the internal leads on the internal bracket; the upper opening is used for installation. Lifting seat, after installing the China Unicom box, you can place a rising seat at the upper opening; the outer wall of the box body is provided with reinforced iron and the inner wall of the box body is welded with an internal bracket. The reinforced iron makes the box body stronger, and the internal bracket It is used to support the internal lead wires, reducing potential safety hazards; a screw rod is connected between the support seat and the box body to move the box body up and down, and the Unicom box can be adjusted to a suitable position through the screw rod.

Preferably, the box body is a rectangular parallelepiped, and each of the eight corners of the box body has a lifting hole on the outer side, so that the communication box can be lifted more conveniently.

Preferably, the internal brackets are uniformly welded on the front side wall and the rear side wall of the box body, and there are 6 on the front side wall and the rear side wall respectively.

Preferably, the reinforcing irons are arranged horizontally and vertically, and the horizontal and vertical arrangement makes the fixing more firm.

Preferably, the support base is connected to the oil tank through studs.

The invention has simple structure and low price, not only makes the installation process convenient and easy to operate, reduces the probability of accidents, ensures the safety of workers, but also is easy to carry and transport, greatly increasing work efficiency.
