Abstract
The utility model discloses a cabinet type power filter comprising three air-core reactors (1) and three capacitors (2). Each air-core reactor (1) is connected with each capacitor (2) through a bus (3). The power filter also comprises three metal cabinet frames (4). Each air-core reactor (1) is respectively arranged on the upper part of each metal cabinet frame (4) correspondingly, and each capacitor (2) is respectively arranged on the lower part of each metal cabinet frame (4) correspondingly, thus forming three phases of the filter. An insulating apparatus (6) is arranged on components (5) that constitute the metal cabinet frame (4), thus causing one end of each component (5) to be insulated from an adjacent component and the other end of each component (5) to be grounded. The power filter is small in occupied area, convenient for installation and good in use effect, and can effectively avoid a circulating-current phenomenon.
Description
Technical field
The utility model relates to a kind of power filter device, relates in particular to a kind of energy compensation network reactive power, improves the cabinet type power filter device of power factor and elimination mains by harmonics.
Background technology
Nonlinear-load in the industrial electrical network, for example: adopt the mill load of DC Transmission, electric furnace steel making load etc. can produce a large amount of harmonic waves in process of production, and the harmonic pollution electrical network forms the harmonic wave public hazards.Simultaneously, the reactive power that nonlinear-load consumption is a large amount of need compensate reactive power, improve power factor, in order to overcome the above problems, the solution that adopts is that the passive electric filtering device is installed usually, and this has obtained using widely in actual engineering.But there is following shortcoming in the passive electric filtering device: because the air core reactor volume that adopts is big, therefore stray field is big especially, the strong magnetic field of reactor can produce circulation in the hardware of the closure around it, circulation produces supplementary load loss and heating, and inductance value is changed, and then make the resonance point of filter depart from, influence power filter device filter effect and quality factor, even certain subharmonic current is amplified, jeopardize the device security of power filter device, in order to address this problem, the existing power filter normally adopts open type to arrange when mounting arrangements, with reference to Fig. 1, but the shortcoming of this electric-power filter is: 1, open type power filter device floor space is big, in practical engineering application, need to set up a bigger space and place the open type power filter device, so construction investment obviously increases.2, owing to reactor in the open type power filter device is very near apart from ground, if closed reinforcing bar loop is arranged in the concrete under the ground of reactor, then reactor is logical power on after, reinforcing bar can generate heat, the quality factor of reactor can be influential, therefore, reinforcing bar will be avoided closed metallic(return) circuit occurring in the ground base concrete of reactor bottom, so bring a lot of inconvenience to design and construction.
The utility model content
The technical problems to be solved in the utility model provides the cabinet type power filter device that a kind of floor space is little, easy for installation and can effectively avoid the circulation phenomenon to produce.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of cabinet type power filter device, comprise three air core reactors and three capacitors, connect by bus between each air core reactor and the capacitor, this cabinet type power filter device also comprises three metal tank brackets, the corresponding respectively top that is located at each metal tank bracket of above-mentioned each air core reactor, the corresponding respectively bottom that is located at each metal tank bracket of each capacitor, form the three-phase of filter, and on the member of forming the metal tank bracket, be provided with seal, make and insulate between end of each member and the adjacent member, and the other end ground connection of member.
The material of described seal is epoxy resin board or bakelite plate.
Compared with prior art, the utility model technology has the following advantages:
1, the utility model floor space is little, and is easy for installation.Compare with existing open type power filter device, the utility model is arranged on air core reactor on the top of metal tank bracket, capacitor is located at the bottom of metal tank bracket, so just make whole filter compact conformation, saved floor space, simultaneously because air core reactor is arranged on the top of metal tank bracket, reactor is distant apart from ground like this, so when mounted concrete foundation is not just needed additional specific (special) requirements, do not avoid in the ground closed metal reinforcing bar loop etc. occurring such as requiring, greatly facilitate installation of the present utility model.
2, the utility model can effectively be avoided the generation of circulation.In the utility model, because an end of all members of the cabinet type power filter device of composition and adjacent member one end insulation disconnection, make and to constitute closed loop between the member, therefore, under the strong stray field effect of reactor, thereby the heating that circulation has been avoided reactor be can not produce, the inductance value of reactor and the quality factor and the filter effect of filter also can not be influenced, owing to the other end ground connection of member, then member can not produce suspension voltage in magnetic field simultaneously.
