Description

Low voltage reactive power compensation cabinet

(1) Technical field: The utility model relates to outdoor power supply systems of electric power enterprises, especially low-voltage reactive power compensation cabinets.

(2) Background technology: The outdoor low-voltage reactive power compensation cabinet is installed in the low-voltage distribution network, and adopts automatic switching parallel capacitor banks in order to improve the power factor and achieve reactive power balance on the spot. It has achieved obvious technical and economic benefits in terms of compensating reactive power required by the power grid, reducing losses and saving energy, improving voltage quality, increasing power grid transmission capacity and utilization of electrical equipment. The low-voltage reactive power compensation cabinet is a cabinet used to integrate various low-voltage reactive power compensation devices into one cabinet. Since the low-voltage reactive power compensation device involves many electrical components and is usually installed outdoors, each manufacturer will produce low-voltage reactive power components with different shapes and sizes according to the external dimensions and design requirements of the selected electrical components. Power compensation cabinet. At the same time, because there are many electrical components in the low-voltage reactive power compensation cabinet, and the cabinet body should not be too large, the layout of the electrical components in the cabinet is often messy. This not only affects the normal operation of the low-voltage reactive power compensation device, but also brings inconvenience to the maintenance and overhaul work of the power department, and even creates potential safety hazards.

(3) Summary of the invention: the purpose of this utility model is to improve the above shortcomings. A low-voltage reactive power compensation cabinet with simple structure, scientific design, clear functional division and convenient installation, operation and maintenance is proposed.

The low-voltage reactive power compensation cabinet of the utility model has a compensation cabinet body, cabinet doors are installed on the front and back sides of the compensation cabinet body, and inlet and outlet holes are opened at the bottom of the left and right sides of the cabinet body, and it is characterized in that: A vertical partition is arranged longitudinally in the middle, which divides the cabinet body into left and right chambers. A vertical beam is arranged in the middle of the two side walls of the left and right chambers, and a vertical small chamber is arranged horizontally between the two vertical beams in each chamber. Partition divides each chamber into two small chambers.

The low-voltage reactive power compensation cabinet is characterized in that ventilation windows are opened on both side walls of the cabinet body.

The low-voltage reactive power compensation cabinet is characterized in that an observation window is opened on the front door of the cabinet body.

The low-voltage reactive power compensation cabinet is characterized in that: the inlet and outlet holes are connected with waterproof elbows with downward outlets.

The low-voltage reactive power compensation cabinet is characterized in that: the bottom of the small chamber on the right side of the cabinet is equipped with a capacitor fixing seat.

The low-voltage reactive power compensation cabinet is characterized in that: at least one connection hole is opened on both sides of the partition of each small chamber.

The low-voltage reactive power compensation cabinet is characterized in that each of the vertical beams is provided with several adjustment holes.

The cabinet body of the utility model has clear functional divisions, modular design, simple structure and convenient installation of electrical components.
