Description

A box type substation box body

technical field

The utility model belongs to the field of electric equipment, in particular to a box-type substation box body.

Background technique

Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme. It replaces the original civil power distribution room. The distribution station has become a new type of complete power transformation and distribution device. Shutters and wire inlet and outlet holes are installed on the traditional substation box to meet the needs of heat dissipation, ventilation, and wire inlet and outlet. However, after encountering rainy weather, rainwater is easy to seep into the substation box from the shutters and the inlet and outlet holes, which will affect the power distribution equipment in the box and easily cause high-risk failures. Moreover, the louvers and wire inlet and outlet holes are used for natural heat dissipation, and the heat dissipation effect is not good. Because the box-type substation is mostly installed outdoors, the conditions are harsh, especially in some heavily polluted areas, where the rainwater is acidic, and the box body will be exposed to rain for a long time, which will accelerate aging.

Utility model content

In order to solve the problems of the above technologies, the utility model provides a box-type substation box, which can effectively improve the heat dissipation effect and avoid rainwater infiltration in the rainy season.

Its technical solution is:

A box-type substation box body, comprising a box cover, a box bottom, a box door, and wire inlet and outlet holes, the wire inlet and outlet holes are arranged on the side of the box cover, and also includes a box bottom interlayer, a ventilation fan and a chassis, the box bottom is provided with a box bottom interlayer, and the box bottom More than one ventilating fan is arranged in the interlayer, the box bottom above and below the ventilating fan is set as a steel mesh, and a chassis is fixedly arranged below the box bottom.

The utility model needs to be installed in a place with high terrain to avoid water accumulation, and the installation foundation should be firm and flat. The base frame is fixedly installed on the foundation, holds up the cabinet, and keeps a distance from the foundation. The ventilation fan at the bottom of the box exchanges the internal and external air through the steel mesh to achieve a good heat dissipation effect and avoid the problem of rainwater penetration in the rainy season.

Furthermore, the bottom frame is an I-shaped bracket composed of channel steel, which has high strength and is easy to install.

Further, the top cover of the box cover is coated with an anti-corrosion coating, a water storage tank is arranged around the top cover of the box cover, and a drainage pipe is connected to the bottom of the water storage tank. The rainwater falls on the top cover of the box cover and gathers in the water tank, and then is discharged by the drain pipe, which prevents the rainwater falling on the top cover of the box cover from sliding down the side of the box cover, and reduces the aging effect of acid rainwater on the side of the box cover. The anti-corrosion coating can improve the corrosion resistance of the top cover of the box cover.

Further, the lower end of the side of the box cover is obliquely provided with a circle of baffles, and the baffles can divert unblocked rainwater to the surroundings of the box to avoid flowing into the bottom of the box.

Further, the inner wall of the inlet and outlet holes is provided with a rubber layer, and an arc-shaped baffle is fixed above the inlet and outlet holes at the outer end of the box cover, and the inlet and outlet holes at the inner side of the box cover are connected to the hole cover through a torsion spring. In a natural state, The hole cover seals the inlet and outlet holes.

When it is necessary to enter or exit the wire, open the hole cover on the inside of the box cover for wiring. If the wire is coming in, you only need to insert the thread end into the hole for the hole to open the hole cover. The rubber layer inside the hole can be better adhered to It fits lines or cables, reduces friction, and also prevents rainwater from penetrating. The idle inlet and outlet holes are sealed by hole covers to prevent rainwater from seeping in. The curved baffle on the outside of the box cover can block rain and sun, and prevent the exposed rubber layer from being exposed to the sun and aging.

The beneficial effects of the utility model:

The utility model replaces the natural heat dissipation of the louvers by using the ventilation method of the box body, improves the heat dissipation effect, avoids the infiltration of rainwater from the louvers, and achieves the moisture-proof effect; the hole cover is set on the inlet and outlet holes to avoid the infiltration of rainwater, and better Fits wires or cables for practicality.
