Description

An easy-to-connect box

technical field

The utility model relates to the field of box-type transformer substations, in particular to an easy-connection box transformer.

Background technique

The bottom of the existing box-type substation (referred to as the box-type substation) is provided with inlet and outlet holes, and the inlet and outlet cables must be inserted or pulled out of the inlet and outlet holes longitudinally from the bottom of the box-type substation. In order to facilitate the operation of construction personnel and to circle the end cable to be installed into the box-type transformer, the depth of the cable well is about 2 meters, and the area is close to the box-type transformer. The existing box substation foundation needs to be excavated and the concrete foundation is poured on site, which is easily affected by the on-site environment and weather, and easily has a great impact on the on-site environment and traffic. The construction period is as long as 20 days, and the cable well is prone to accumulation of water and moisture. From the box-transformer cable well into the box-transformer, condensation and frost will occur inside the box-transformer, reducing the electrical performance of the box-transformer.

Utility model content

Aiming at the deficiencies of the prior art, the utility model provides an easy-connection box transformer to solve the above-mentioned technical problems.

The technical scheme of the utility model provides an easy-to-connect box transformer, the base of the box transformer is provided with a C-shaped inlet and outlet hole, the upper part of the C-shaped inlet and outlet is provided with an inlet and outlet box door, and the inlet and outlet cables pass through the C-shaped inlet and outlet wires. The opening of the hole and the opened door of the incoming and outgoing line box are laterally moved into or out of the box.

As a preference of the present invention, the opening is provided with a sealing member, and the sealing member is fastened inside the box.

The utility model has the following beneficial effects: 1. The difficulty of cable entry construction is greatly reduced; 2. The cable well in the box-transformation foundation can be eliminated, the construction period can be shortened, the impact on the environment and the cost; 3. Water accumulation in the cable well can be avoided Causes the box to become damp, reducing the risk of electrical performance degradation.

Fig. 1 is the installation schematic diagram of a kind of easy-to-connect box transformer inlet line of the present invention;

Fig. 2 is a schematic diagram of the operation state of an easy-connect box transformer of the present invention.

Detailed ways

The present utility model will be further described in detail below in conjunction with the accompanying drawings.

As shown in FIG. 1, as an embodiment of the solution of the present utility model, an easy-to-connect box transformer, the base 8 of the box transformer 1 is installed on the base 2, and the base 8 is provided with a C-shaped inlet and outlet hole 3 by the frame, and the C-shaped inlet and outlet Above the wire hole 3 is set an incoming and outgoing wire box door 4, and the incoming and outgoing wire cable 6 is moved laterally into or out of the incoming and outgoing wire cabinet 5 of the box transformer 1 through the opening of the C-shaped incoming and outgoing wire hole 3 and the opened incoming and outgoing wire box door 4. During the construction process, the operation difficulty of the workers moving the cable in and out of the cable laterally by swinging on the ground is greatly reduced compared with the traditional operation difficulty of pushing and pulling the cable under the cable well. The cable well in foundation 2 can be eliminated, which is beneficial to the use of prefabricated foundations, shortening the construction period from about 20 days to 1 day, reducing the impact on the environment and reducing costs.

As shown in FIG. 2 , a sealing member 7 is provided at the opening, and the sealing member 7 is fastened with bolts inside the box changer 1 . The incoming and outgoing cables 6 can be laid through the cable trench or directly buried to the edge of the box transformer, which is more flexible and convenient. In the running state of the box-type transformer, avoid water accumulation in the cable well causing the box-type transformer to become damp, and reduce the risk of electrical performance degradation.

The above-mentioned embodiments merely describe the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Under the premise of not departing from the design concept of the present invention, various modifications and improvements made by ordinary persons in the art to the technical solutions of the present invention shall fall within the protection scope of the present invention. The content has been fully described in the claims.

Claims (2)
