Description

A JP cabinet for heat dissipation

technical field

The utility model relates to the technical field of electric equipment, in particular to a JP cabinet which is convenient for heat dissipation.

Background technique

JP cabinet refers to the compensation distribution cabinet used for low-voltage power distribution system, which is generally installed under the transformer. At present, 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 prevention), and capacitor reactive power compensation.

In the current JP cabinet, there are a large number of electrical components built in the cabinet cavity, which will generate working heat; at the same time, JP cabinets usually use metal cabinets. promote. In order to facilitate heat dissipation, the traditional method is to directly set up heat dissipation windows on the side of the cabinet cavity, hoping to solve the heat dissipation problem through air convection, but the effect is often unsatisfactory in actual operation. The ideal state is that the wind will enter through one side of the heat dissipation window and fill the cabinet cavity, and will be taken out by the other side of the heat dissipation window with the airflow; however, due to the electrical connection problems of the electrical components in the cabinet cavity, it is often necessary to arrange an additional whole block The shielding partition, that is, the isolation steel plate, is used to achieve the electrical isolation effect of the two sets of electrical components; the existence of the entire isolation steel plate will reduce the airflow velocity in the cabinet cavity, or even directly cut off the flow path of the airflow, which is obviously not conducive to the air flow. The formation of the convective flow field greatly affects the actual cooling effect. On the other hand, in a windless environment, there is no external wind to affect the airflow in the cabinet cavity, and the hot air in the cabinet cavity will naturally rise and converge to the top of the cabinet cavity, and cannot be directly discharged quickly through the heat dissipation window on one side, resulting in The phenomenon of heat accumulation at the top of the cavity is also not conducive to actual heat dissipation. Therefore, urgently need to solve.

The ventilation holes on the perforated partition 15 and the heat dissipation window 11 form an airflow circuit, thereby forming a heat dissipation channel. When the two sides of the JP cabinet are affected by the wind, the wind drives the airflow to enter along the heat dissipation window 11 on the side of the JP cabinet, and takes away the heat inside the cabinet along the heat dissipation channel, so that the heat in the JP cabinet can be quickly dissipated. Disperse. This not only improves the heat dissipation effect of the JP cabinet, but also prevents the electrical components in the JP cabinet from malfunctioning due to poor heat dissipation, and strengthens the stability of the JP cabinet.
