Description

Power metering and load control integrated cabinet with high heat dissipation

technical field

The utility model belongs to the field of electric equipment, in particular to an electric energy metering and load control integrated cabinet with high heat dissipation.

Background technique

At present, domestic user substations basically adopt the method of installing an electric energy metering cabinet and adding an electric load control cabinet (1+1). One metering cabinet (2200x600x600mm) only installs one electric energy meter, and the power load control cabinet and the meter also need to be connected by cables. There are dozens of items of various data displayed on the electric energy meter and electric load control terminal in the application, which need to be turned over many times to view, and it is difficult for non-professionals or people without a certain technical foundation to understand. For example: to check the electricity consumption and electricity bill, the conversion ratio and unit price are required, which is not intuitive. In addition, many parameters do not need to be known by the user. Electric energy meters and load control terminals are equipment for the majority of electric power users, so a device that enables ordinary users to understand their own electricity consumption, electricity charges, indicators and other practical data at a glance is needed. Its disadvantages include: 1. Waste materials, such as cabinets and cables; 2. Occupy space resources, and the metering room needs to install at least two cabinets. 3. The safety performance is reduced and the anti-interference ability is weakened. 4. Increase construction cost and consume manpower and material resources.

In order to solve the above technical problems, people integrate the two boxes together according to the characteristics of the electrical connection between the two. Although the integrated electric energy metering and load control integrated cabinet effectively solves the traditional technical problems, However, due to the combination of various electrical components, the heat generated during their work is also greatly increased. Simply relying on traditional cooling holes cannot effectively reduce the temperature in the cabinet, thereby greatly reducing its service life.

detailed description

In order to understand more clearly the above purpose, features and advantages of the utility model, the utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

In the following description, a lot of specific details have been set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways that are different from those described here. Therefore, the utility model is not limited to the specific details of the following disclosure EXAMPLE LIMITATIONS.

Embodiment 1, as shown in Fig. 1, Fig. 2 and Fig. 3, the utility model provides an electric energy metering and load control integrated cabinet with high heat dissipation, including a cabinet body 1 and arranged in the cabinet body sequentially from top to bottom The four cavities 2 on 1 are equipped with electronic components for electric energy metering and load control. The above structures are all existing common integrated cabinet structures, so in this embodiment, no details description, in this embodiment, the key point of improvement is that heat dissipation holes 3 are provided on the side wall of the cabinet body 1, specifically, the heat dissipation holes 3 are uniformly arranged on the side wall of the cavity 2, in order to increase Heat dissipation effect, a heat dissipation fan is arranged on the back of the cabinet body 1, and the heat dissipation fan is also arranged on the back of the cavity 2. In the present embodiment, the heat dissipation fan includes a blower 4 and an exhaust fan 5. As the name suggests, the main function of the blower 4 is to Air is blown into the cabinet to generate flowing wind, and the effect of exhaust fan 5 is to extract the air in the cabinet, and the purpose is to generate flowing wind in the cabinet 1 equally. A greater effect can be produced in the cabinet. In this embodiment, the blower 4 and the exhaust fan 5 are symmetrically arranged on the back of the cabinet 1.
