Description

A Practical Electric Outdoor Convenience Inspection JP cabinet

technical field

The utility model relates to the field of electric power, in particular to a practical electric power outdoor convenience inspection type JP cabinet.

Background technique

Distribution transformer integrated power distribution cabinet is referred to as JP cabinet for short. With the continuous deepening of rural power grid transformation, a large number of JP cabinets are used in rural power lines and distribution stations. JP cabinet is designed to meet the standardization, miniaturization and outdoor requirements of rural low-voltage power distribution equipment. It integrates power distribution, measurement, protection (overload, short circuit, leakage, snow protection), and capacitor reactive power compensation. In addition, a large number of electrical components are integrated inside the JP cabinet, which is very important for the waterproof of the JP cabinet; for the JP cabinet installed outdoors, because it needs to experience rainy weather for many years, its waterproof requirements are much higher than that of the indoor JP cabinet.

At present, although the outdoor JP cabinet needs to be considered waterproof, it still needs to dissipate heat. Therefore, there are cooling vents on the side wall of the cabinet. Generally, for waterproofing, the cooling vents are made into strip-shaped shutters, and each strip dissipates heat. There is a rain cover above the mouth. Due to the blocking of the rain cover, it is difficult for the rainwater blowing horizontally with the wind to enter the cabinet; however, it is also difficult for the airflow blowing horizontally to enter the cabinet, which limits the heat dissipation performance of the JP cabinet to a large extent.

Contents of the invention

The purpose of this utility model is to provide a practical electric power outdoor inspection type JP cabinet, which can not only effectively waterproof and allow the airflow to enter the cabinet reliably, but also ensure the good heat dissipation performance of the power cabinet. Through the design of this scheme, it is very convenient for people to check the metering electricity display number of the JP cabinet.

The utility model is realized in this way, a practical electric power outdoor inspection type JP cabinet, including the metal shell of the JP cabinet, heat dissipation windows, drainage windows, sliding windows, and rainproof covers; it is characterized in that: the top of the JP cabinet metal shell is set There is a rain cover, and there are sliding windows on the front of the metal shell of the JP cabinet, drainage windows are respectively set on the two sides and the back of the metal shell of the JP cabinet, and heat dissipation windows are set on the lower end of the metal shell of the JP cabinet; the shape of the rain cover is It is in the shape of eaves, and the rain cover is composed of two roof panels, a support frame and four rainproof films; the support frame is a frame structure, and the four supports on the support frame are set on the four edges of the metal shell of the JP cabinet , or welded, or connected by bolts, the upper end of the support frame is provided with two roof panels, and is connected by a rainproof film between every two supports, and the rainproof cover covers the upper part of the metal shell of the JP cabinet to prevent The rainwater enters the outdoor toilet inspection type JP cabinet and causes electric leakage.

The sliding window described in the utility model is composed of push-pull plexiglass and a push-pull handle; the upper end of the metal shell of the JP cabinet is provided with push-pull plexiglass, and a push-pull handle is arranged on the push-pull plexiglass; people can push and pull the window through the push-pull handle. The plexiglass is opened, which is convenient to check the metering number in the cabinet, and will not cause small animals to enter the cabinet.

The heat radiation window described in the utility model is arranged at the lower end of the metal shell of the JP cabinet, and is in a louver structure. The strip heat radiation window includes a rain cover for covering the rain, which is not only rainproof, but also prevents mice from entering.

The drainage window of the utility model is surrounded by three sides, a top surface and a bottom surface; the bottom surface is provided with a bottom surface through hole connecting the interior of the drainage window and the outside world; The wall hole inside the drainage window.

The position height of the drainage window and the sliding window described in the utility model are the same, and the positions of the four windows are respectively arranged around the JP cabinet.

The lower end of the metal shell of the JP cabinet described in the utility model may be provided with four rollers, which are respectively arranged at the bottom of the metal shell of the JP cabinet, and a support bar is arranged next to the rollers. It is designed with rollers, which greatly facilitates the use of the staff. When the JP cabinet does not need to be moved, it is fixed by the support rod; the length of the support rod is slightly higher than the diameter of the roller.

The utility model has the advantages of simple structure and convenient use, and the push-pull plexiglass window can more clearly check the electricity indication of the metering meter in the JP cabinet, which relieves people from using the JP cabinet for a long time. The troubles that cannot be seen clearly, and will not cause small animals to enter the cabinet; the JP cabinet is set with the drainage window. When the air flow blows the power cabinet horizontally, the paths of the air flow through the top surface and the bottom surface of the drainage window are different, resulting in drainage. If the air velocity on the top side of the window is greater than that on the bottom side of the drainage window, according to the principle of fluid mechanics, the pressure on the bottom side of the drainage window will be greater than the pressure on the top side, thus causing the air under the drainage window to press upwards and enter the drainage The inside of the window, and enter the JP cabinet through the wall hole on the JP cabinet wall, and form air convection inside the power cabinet through the strip-shaped heat dissipation window under the cabinet wall; the top of the JP cabinet is designed with a rain cover to prevent rainwater from entering the outdoor toilet In the inspection type JP cabinet, and cause leakage phenomenon, etc.
