Description
Technical field
The utility model relates to filter, particularly a kind of modular filtering compensation device.
Background technology
In service at present equipment, because the use of a large amount of power electronics kind equipments, so inevitably can produce the problem that harmonic pollution etc. affects the quality of power supply.Because low-pressure reactive compensation is compensated for as the master with pure capacitance, and the characteristic of electric capacity itself is capacitive, along with the raising of harmonic frequency, the capacitive reactance meeting of electric capacity is along with frequency reduces, the current effective value that flows through capacitor is increased, accelerate capacitor insulation aging, even the situation such as capacitor blast occurs.Usually, traditional low-voltage compensation apparatus is disperseed to be installed in the low voltage complete set by control switch (or fuse), switching device, power capacitor, line between them is connected when capacitor panel is assembled by complete set of equipments producer, complex structure, install inconvenient, also can disturb other power consumption equipment, therefore, the improvement of compensation arrangement is the problem of needing at present solution badly.
Summary of the invention
For above-mentioned situation, for solving the defective of prior art, the purpose of the utility model just provides a kind of modular filtering compensation device, can effectively solve the prior art complex structure, and inconvenient problem is installed.
The technical scheme that the utility model solves is, comprise modulus framework, switch with knifeshaped fuse, thyristor throw-cut device and filter reactor, filter reactor and filtering capacitor are housed in the modulus framework, switch with knifeshaped fuse and thyristor throw-cut device are equipped with in modulus framework front, switch with knifeshaped fuse links to each other with the thyristor throw-cut device, the thyristor throw-cut device links to each other with filter reactor, and filter reactor links to each other with filtering capacitor.
The utility model operating passing zero, fast response time, full cast structure, sturdy and durable, built-in cooling fan; automatically the start and stop of control fan are built-in with the overheat protector function, and integrated, volume is little; easy for installation, the safe interconnection technique of very touch-type, long service life is the innovation on the compensation arrangement.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Provided by Fig. 1-4, the utility model comprises modulus framework 3, switch with knifeshaped fuse 1, thyristor throw-cut device 2 and filter reactor 4, filter reactor 4 and filtering capacitor 5 are housed in the modulus framework 3, switch with knifeshaped fuse 1 and thyristor throw-cut device 2 are equipped with in modulus framework 3 fronts, switch with knifeshaped fuse 1 links to each other with thyristor throw-cut device 2, thyristor throw-cut device 2 links to each other with filter reactor 4, and filter reactor 4 links to each other with filtering capacitor 5.
In order to guarantee result of use, described filtering capacitor 5 is cylindrical.
Described modulus framework 3 is be made of metal square.
The utlity model has following advantage:
1) the capacity assembling has nothing to do with the cabinet type flexibly.Adopt standardized module, freedom is the assembly unit capacity as required, can be fit to the cabinet of multiple pattern.
2) wiring and composite assembly are convenient.Use module as playing with building blocks, can be combined into as required the progression of various capacity.
3) interface is simple, is convenient to automation.A module has relatively independent system of one's own, and electrical network interface and control interface externally are provided.The ripe design of inside modules is also assembled complete being up to the standards.Reactive power compensator with the off resonance reactance complicated calculating and design have been save especially.
4) compact conformation, the assembling capacity is large.The more traditional fixed installation of single cabinet capacity increases at least one times.
5) the place capacity expansion freely.Along with the development that enterprise produces, reactive compensation capacity can increase at any time module when not enough and carry out dilatation.
6) maintenance is convenient.Maintenance, upgrading Portable safety.
The utility model operating passing zero, fast response time, full cast structure; sturdy and durable, built-in cooling fan is controlled the fan start and stop automatically; be built-in with the overheat protector function; integrated, volume is little, and is easy for installation; the safe interconnection technique of very touch-type; long service life is the innovation on the compensation arrangement, has good economic and social benefit.
