Low voltage compensation capacitor is a kind of commonly used power equipment, which is used to adjust and improve the power factor of power system. Correct selection can ensure the stable operation of the system and the energy saving effect. So, in many low-voltage compensation capacitor models, how to choose?
1. Consider power factor correction capability
The low-voltage compensation capacitor is mainly used to adjust the power factor of the power system. Therefore, when choosing a model, the first thing to consider is the power factor correction capability of the capacitor. Usually, we will pay attention to the rated power factor of the capacitor, that is, the maximum power factor correction capability that the capacitor can achieve. According to your needs, choose a capacitor model that can meet the system requirements.
2. Determine the rated capacity
In addition to the power factor correction capability, the rated capacity of the capacitor needs to be considered. The rated capacity represents the amount of electrical energy that the capacitor can store, usually in kvar. When selecting, the appropriate rated capacity should be determined according to the load situation of the system and the number of equipment that needs power factor correction. Generally speaking, the rated capacity should be slightly larger than the load demand of the system to ensure the normal operation of the capacitor and the stability of the system.
3. Understand the type of capacitor
There are many different types of low-voltage compensation capacitors, including fixed capacitors, variable capacitors, and automatic capacitors. Fixed capacitor is the most common type, the capacity is fixed, power factor correction is generally more stable. The variable capacitor can adjust the capacity in real time according to the load situation of the system to adapt to different working conditions. The automatic capacitor can automatically sense the load change of the system and adjust the capacity in real time, which has a higher degree of intelligence. When selecting the model, the appropriate capacitor type should be selected according to the system requirements and the actual situation.
4. Consider the working environment of the capacitor
During the use of low-voltage compensation capacitors, it is necessary to consider the working environment in which they are located. Some working environments may have high temperature, humidity or corrosive substances, which will affect the performance and life of the capacitor. Therefore, in the selection, should be selected according to the actual environmental conditions with the corresponding material and protection level of the capacitor, to ensure that it can work in a difficult working environment.
5. Refer to relevant standards and specifications
In the selection process, you can refer to the relevant standards and specifications, such as national standards, industry standards or the requirements of power companies. These standards and specifications provide some guidance on the selection and use of capacitors, which can help you better choose the right model.
