Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The utility model provides a nuclear power station middling pressure transfer box that can normally use after having good anti-seismic performance and tsunami accident operating mode water logging, its characteristics lie in that the structure is succinct, and equipment is opened, is closed in a flexible way, and equipment is whole to have high protection, high anti-seismic performance. The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Fig. 1-5 show a medium voltage transfer box provided by the present invention.

As shown in fig. 1, the junction box is composed of the components listed in fig. 1, and is composed of a box frame 101, an inner door 102, and an outer door 103. The box frame is connected with the outer door support in a welded mode, the inner door is installed on the inner side of the outer door support, the inner high-voltage electricity is effectively isolated to the outside, the side edge of the outer door is connected with the box frame through a hinge, and then the outer door support is installed on the outer door support through fastening screws. The outer door is supported as a rectangular frame.

As shown in fig. 2, the box frame has a simple structure, and the high anti-seismic performance of the box is realized by 4 reinforcing brackets arranged inside the box frame, and the reinforcing brackets are symmetrically distributed at the upper, lower, left and right positions of the box frame; the mounting rectangular pipes are also located at the four bottom corners of the box frame in this manner. In the embodiment, the preferable reinforcing support is of a Z-shaped structure, so that the rigidity of the box body can be effectively enhanced, and the installation and arrangement of the devices in the equipment at any depth and height can be realized by the designed equidistant holes.
