technical field

The utility model relates to the field of power distribution systems, in particular to an intelligent reactive power compensation distribution box.

Background technique

Reactive power compensation refers to a measure taken in the power system to improve the reactive power balance of the network. The reactive power compensation distribution cabinet can be realized by connecting reactive power capacitors, inductors and other equipment in series or in parallel in the circuit. While ensuring voltage stability, it can reduce transmission loss, improve power quality and effectively utilize grid capacity.

It is a common design that capacitors are installed on the front and rear sides of the reactive power compensation distribution cabinet, but other electronic components on one of the surfaces are therefore located in a deeper position in the cabinet. At the same time, the power distribution cabinet can work normally without maintenance When in use, these electronic components can better prevent them from being damaged by impact in a deeper position, but there are indeed difficulties in operation and maintenance. For example, insufficient operating space requires deeper access to the interior of the power distribution cabinet for maintenance or operation, Obstructed line of sight makes it difficult for the operator to clearly see the components that need to be operated, thereby increasing the risk of misidentification and misoperation, causing inconvenience to use, and requiring the operator to extend the body or arm into a deep position for operation, It not only causes inconvenience to use, but also has potential safety hazards.

Compared with the prior art, the utility model has the following beneficial effects:

The utility model installs an adjustment assembly that can slide forward and backward in the cabinet, and installs the power-feeding element on the adjustment assembly. During maintenance, the sliding seat slides on the slide rail to drive the power-feeding element to move outward to the required position. Then the position of the sliding seat is fixed by the rotation of the fixed rod to drive the elastic plug to clamp the pulley. At this time, the maintenance personnel can directly inspect the power-feeding components on the buckle rail without putting the body and arms deeply into the distribution box. Inside the electric cabinet, at the same time, the line of sight will not be misunderstood because it is too deep. After the inspection is completed, push the sliding seat back to its original position and then lock the screw to fix it, which is convenient for use.

Detailed ways

The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

Embodiment: As shown in Figure 1-Figure 4, the utility model provides an intelligent reactive power compensation distribution box, its structure includes a cabinet body 1 with a cabinet door 2, and the front and rear sides of the cabinet body 1 are equipped with The cabinet door 2 and the cabinet body 1 are equipped with reactive capacitors 5 and are located on the front and rear sides of the cabinet body 1. The front and rear cabinet doors 2 provide openings for the reactive capacitors 5 on the front and rear sides of the cabinet body 1 respectively. An adjustment component 6 is provided in the upper-end incoming line area, and the power supply element 4 is installed on the adjustment component 6, and the incoming wire is connected to the line terminal of the power supply component 4.
