Three-phase imbalance compensation cabinet type active filter

Abstract

The invention relates to a three-phase imbalance compensation cabinet type active filter. A door plate assembly comprises a door plate, a sealing ring and two fixing strips arranged in parallel. A double-layer framework set is fixed between the two fixing strips, the sealing ring surrounds a door plate inner plate, the fixing strips, the double-layer framework set fixed between the fixing strips and a door plate middle plate to form a door plate sealing part. A door plate assembly is rotatably fixed to the opening face of the single-face-open box body in an openable and closable mode, and whenthe door plate assembly is closed, the door plate outer plate covers a sealing frame, and the door plate sealing part enters the single-face-open box body. According to the three-phase imbalance compensation cabinet type active filter of the invention, the box structure of the active filter is integrally detachable, and a three-layer plate structure based on the double-layer framework can realizeefficient sound insulation on the premise of ensuring light weight; due to the arrangement of the door plate assembly, the cabinet type box body is convenient to open, the sound insulation and shockabsorption effects are achieved, the position of the support is adjustable, more possibilities are provided for the erecting position of an electronic system, and the possibility of modularly increasing assemblies is also provided.

Description

technical field [0001] The invention belongs to the field of active filter structures, and in particular relates to a three-phase unbalance compensation cabinet-type active filter. Background technique [0002] The use of electronic equipment often has heat and heat dissipation problems. If there is no effective treatment, the efficiency of electronic equipment will be reduced or damaged. As a harmonic control device, the active filter generates more heat, which leads to a larger number of internal fans. Some active filters are equipped with multiple cooling methods to work together to achieve effective cooling. It can be seen that the heat generation of active filters is very serious. For non-research institutions, there is generally no air conditioning in the computer room, and the high temperature inside the computer room hinders the cooling efficiency of the active filter. [0003] Active filters operate with cooling fan noise and component current noise common to elec...

Problems solved by technology

However, it is difficult to achieve a good shock absorption and sound insulation effect in a small size with a cabinet door active filter

For the adjustment of the position of the components in the active filter, it is very difficult to make it simple without affecting the effect of sound insulation and vibration isolation.
