Abstract
The utility model relates to a high efficiency filter, including the filter body, the upper end of the filter body is the toper oil inlet, the filter is internal to be provided with three filter screen, is filter screen I, filter screen II and filter screen III respectively, the cross -section of filter screen I is " U " type, the cross -section of filter screen II is " V " type, the cross -section of filter screen III is taperedly, and filter screen I, filter screen II, III from the top down of filter screen set gradually on the inner wall of the filter body, form between the adjacent filter screen and filter the passageway. The utility model has the advantages of simple structure and reasonable design, small quality is light, cheap, convenient to use, can carry out the oil strain operation effectively, is convenient for use when the transformer maintains.
Description
Technical field
The utility model relates to filter plant technical field, particularly relates to a kind of high efficiency particulate air filter.
Background technology
Transformer utilizes the principle of electromagnetic induction to change the device of alternating voltage, and main member is primary coil, secondary coil and iron core (magnetic core).Major function has: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilizing (magnetic saturation transformer) etc.Can be divided into by purposes: power transformer and special transformer (electric furnace change, rectification change, power frequency testing transformer, voltage regulator, mining change, audio frequency transformer, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, instrument transformer etc.).Transformer is equipment conventional in a kind of transmission line system, and its Main Function is the conversion for carrying out circuit voltage.Due to the operating voltage of its superelevation, transformer just must be made to have cocksure insulation property, and there is fabulous heat dispersion, we just will add a kind of transformer oil for improving insulating properties and thermal diffusivity in transformer, due to the reason of transformer oil, when transformer break down need overhaul time, the inconvenience of maintenance will be there will be, for this reason, for convenience of maintenance, will first clean for the transformer oil filter in transformer, existing filtering oil for transformer device fabrication is complicated, and cost is higher.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of high efficiency particulate air filter, oil strain is effective, and makes simple, with low cost, is convenient to promote the use of.
The utility model is achieved through the following technical solutions:
A kind of high efficiency particulate air filter, comprise filter body, the upper end of described filter body is taper oil-in, three screen packs are provided with in described filter body, be respectively screen pack I, screen pack II and screen pack III, the cross section of described screen pack I is " U " type, the cross section of described screen pack II is in " V " type, the cross section of described screen pack III is tapered, and screen pack I, screen pack II, screen pack III are successively set on the inwall of filter body from top to bottom, between described adjacent screen pack, form filtration channel.
As optimal technical scheme of the present utility model, the sidewall bottom of described filter body is provided with flowline, and described flowline is provided with manual modulation valve.
As optimal technical scheme of the present utility model, the upper end of described filter body is movably hinged with cover plate by bearing pin, and the upper end of described cover plate and taper oil-in is suitable.
As optimal technical scheme of the present utility model, the upper end length of described taper oil-in is greater than lower end length.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the little quality of volume is light, cheap, easy to use, filter efficiency is high, effectively can carry out oil strain operation, be convenient to use when transformer maintenance.
