Background technique

With the acceleration of urban and rural modernization, urban construction has entered the stage of urban beauty aimed at improving streetscapes and city appearances. Traditional box-type substations occupy a large area, especially in residential areas where power distribution rooms need to be installed, which not only affects the overall beauty of the area and roads, but also emits transformer noise that seriously affects the health and life of residents.

A box-type substation usually includes a transformer and a power distribution unit such as a high-voltage cabinet and a low-voltage cabinet connected to the transformer. The existing solution to the above problems is usually to bury the whole or part of the box-type substation underground. Although it can solve the problems of unsightly appearance and noise, it is expensive and inconvenient to repair and maintain.

Utility model content

Aiming at the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a split-type underground box-type substation capable of eliminating noise and convenient for maintenance.

According to the technical solution provided by the utility model, a split-type underground box-type substation includes a box body, a transformer arranged in the box body, a high-voltage cabinet and a low-voltage cabinet, the box body is all buried under the ground, and the high-voltage cabinet The cabinet and the low-voltage cabinet are arranged on the ground, and a well-sealed cable inlet and outlet hole is arranged on the box body, and the transformer is connected to the high-voltage cabinet and the low-voltage cabinet through the cables arranged in the cable inlet and outlet holes.

Preferably, the box body is made of non-metallic insulating material.

Preferably, the box is provided with an air inlet, an air outlet, and a water outlet, and the box is provided with a submersible pump for automatic drainage and a fan for ventilation and heat dissipation.

Preferably, the box is provided with a transformer protection net, which divides the box into a personnel activity area and a transformer placement area, and a personnel entrance and exit is provided on the box above the personnel activity area, and the personnel entrance and exit Provide well-sealed manhole covers.

Preferably, a distribution box is arranged on the ground above the box, and the high-voltage cabinet and the low-voltage cabinet are arranged in the distribution box.

Compared with the prior art, the utility model has the advantages that: since the utility model divides the box-type substation into two parts, the transformer that generates the noise source is buried under the ground, and the high-voltage cabinet and low-voltage cabinet that need to be repaired and maintained are distributed. The electrical equipment is placed on the ground, which not only eliminates noise but also facilitates the maintenance of the staff, and the small footprint does not affect the surrounding environment.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

As shown in Figures 1 and 2, a split-type buried box-type substation includes a box body 1, a transformer 2 arranged in the box body 1, a high-voltage cabinet 3 and a low-voltage cabinet 4, and the box body 1 is all Buried under the ground, the high-voltage cabinet 3 and the low-voltage cabinet 4 are arranged on the ground. A well-sealed cable inlet and outlet hole 5 is arranged on the box body 1, and the transformer 2 is connected with the high voltage cabinet 3 and the low voltage cabinet 4 through the cables arranged in the cable inlet and outlet holes 5.

The high and low voltage cable inlet and outlet holes 5 of the box-type substation adopt imported submarine cable sealing technology. Sealing systems with multi-path technology can seal cables or pipes of different diameters. The cable entry and exit hole seal is detachable and reusable to ensure the waterproof performance of the entry and exit cables.

The box body 1 in this embodiment is made of non-metallic insulating material, has good mechanical strength, can resist pressure, impact and aging, is anti-corrosion and waterproof, has stable cold and hot performance, small temperature difference change, and long service life: up to 50 more than a year.

The whole box body 1 is fully enclosed, and is buried in a pre-dug transformer pit. The box body is provided with an air inlet 6, an air outlet 7, and a water outlet (not shown in the figure), and the box body 1 is provided with a submersible pump 9 for automatic drainage and a fan 10 for ventilation and heat dissipation, forming a good wind circulation System and drainage system, so that the transformer 2 buried under the ground can work normally in the box body 1, prolong its service life, and improve the reliability of the power supply system.

A transformer protection net 11 is arranged inside the box body 1 , which divides the box body 1 into a personnel activity area 12 and a transformer placement area 13 . The casing 1 above the personnel activity area 12 is provided with a personnel entrance and exit 14, and a well-sealed manhole cover 15 is provided on the personnel entrance and exit 14, and the casing 1 is sealed to protect equipment such as transformers 2 in the casing 1.

A distribution box 16 is arranged on the ground above the box body 1, and the high-voltage cabinet 3 and the low-voltage cabinet 4 are arranged in the distribution box 16, which is convenient for staff to overhaul and maintain. In other embodiments, the distribution box 16 can be made into an outdoor advertising light box or matched with the greening of the community to beautify the environment of the community or the street.

Because the utility model divides the box-type substation into two, the transformer that generates the noise source is buried under the ground, and the high-voltage cabinet, low-voltage cabinet and other power distribution equipment that need to be repaired and maintained are placed on the ground, which not only eliminates noise but also facilitates work. Personnel inspection and maintenance, and the small footprint does not affect the surrounding environment.

The utility model also can have other various embodiments, without departing from the spirit and essence of the utility model, those skilled in the art can make various corresponding changes and deformations according to the utility model, but these corresponding changes and All deformations should belong to the protection scope of the claims of the present utility model.
