The utility model discloses owing to increased the rubber shock absorber pad between transformer core and mounting bracket and base for whole equipment has possessed good shock attenuation effect, has improved the security performance when transporting and assembling, has protected transformer core not receive the damage effectively, owing to fasten with the rivet, improved machining efficiency, riveting back firm in connection, the steady quality is favorable to the efficiency of stabilizing transformer, the use of insulating cover makes the security performance of transformer further improve.
Description
(1) technical field
This utility model relates to electric power facility field, particularly to a kind of transformer core group.
(2) background technology
Power transformer is a kind of static electrical equipment, is used to become the alternating voltage (electric current) of a certain numerical value the equipment of the different voltage (electric current) of the identical another kind of or several numerical value of frequency.When a winding passes to alternating current, just producing the magnetic flux of alternation, the magnetic flux of alternation passes through iron core magnetic conduction effect, just induces AC electromotive force in Secondary Winding.The height of secondary induction electromotive force and the number of a Secondary Winding number of turn are relevant, i.e. voltage swing is directly proportional to the number of turn.Main Function is transmission electric energy, and therefore, rated capacity is its major parameter.Rated capacity is the usual value of a performance power, and it is the size characterizing transmission electric energy, represents with KVA or MVA, when transformator is applied rated voltage, determines under prescribed conditions less than the rated current of temperature limit according to it.The iron core apparatus of power transformer, in an iron core cylinder, is provided with insulating barrier between iron core and iron core barrel, it is the most convenient that traditional transformator is installed in use, and damping effect is poor.Generally being fastened together by four screw rods after transformer core overlapping, bolt and nut is fastened by craft screwdriver, and efficiency of assembling is difficult to improve；During using besides, bolt and nut can loosen so that transformer core can not paste jail, reduces the efficiency of transformator.
(3) summary of the invention
This utility model is in order to make up the defect of prior art, it is provided that the transformer core group of a kind of easy to clean dust.
This utility model is achieved by the following technical solution:
A kind of transformer core group, including the transformer core being fixed overlapping by securing member, it is characterized in that, described transformer core has three groups, described three groups of transformer cores are arranged on pedestal, described three groups of transformer core upper ends are commonly connected on installing rack, on described installing rack, shackle plate is installed, through hole is had on described shackle plate, binding post is connected on described installing rack, described binding post is connected with transformer core by conductive pole, lower Rubber shock-absorbing pad it is provided with between described pedestal and transformer core, it is provided with Rubber shock-absorbing pad between described transformer core and installing rack；Described securing member is rivet, and described rivet is wrapped with insulation sleeve, and described rivet includes rivet rod and punched openings, and the length of described rivet rod, equal to the width of transformer core, is cased with electro-insulating rubber pad at described punched openings.
The length in the bar portion of described insulation sleeve is equal to the width of transformer core.
The beneficial effects of the utility model are:
This utility model is owing to adding Rubber shock-absorbing pad between transformer core and installing rack; lower Rubber shock-absorbing pad is added between pedestal and transformer core; whole equipment is made to have possessed good damping effect; security performance when improve transport and assemble, is effectively protected transformer core without damage；Owing to being fastened with rivet, the course of processing uses the disposable stamping riveting of punching press frock, improves working (machining) efficiency, be connected firmly after riveting, the efficiency of steady quality, beneficially stabilizing transformer；The use of insulation sleeve makes the security performance of transformator improve further.
(4) accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is further described:
Fig. 1 is main TV structure schematic diagram of the present utility model；
Fig. 2 is the sectional structure schematic diagram of rivet.
In figure, 1 transformer core, 2 pedestals, 3 times Rubber shock-absorbing pads, 4 installing racks, Rubber shock-absorbing pad on 5,6 shackle plates, 7 through holes, 8 conductive poles, 9 binding posts, 10 rivets, 11 head ends, 12 rivet rods, 13 punched openings, 14 insulation sleeves, 15 electro-insulating rubber pads.
(5) detailed description of the invention
Accompanying drawing is specific embodiment of the utility model.Such as Fig. 1, shown in Fig. 2, this kind of transformer core group, including the transformer core 1 being fixed overlapping by securing member, transformer core 1 has three groups, three groups of transformer cores 1 are installed on the base 2, between transformer core 1 and pedestal 2, upper and lower Rubber shock-absorbing pad 3 is padded during installation, these three groups of transformer core 1 upper ends are jointly on installing rack 4, Rubber shock-absorbing pad 5 on padding between transformer core 1 and installing rack 4 during installation, installing rack 4 is provided with shackle plate 6, through hole 7 is had on shackle plate 6, binding post 9 is connected on installing rack 4, binding post 9 is connected with transformer core 1 by conductive pole 8；Securing member uses rivet 10, rivet 10 includes head end 11, rivet rod 12 and punched openings 13, head end 11 and punched openings 13 lay respectively at the two ends of rivet rod 12, the insulation sleeve 14 being made into integration it is wrapped with at head end 11 and rivet rod 12, the length of rivet rod 12, equal to the width of transformer core 1, is cased with electro-insulating rubber pad 15 at punched openings 13.
In addition to technical characteristic described in description, remaining technical characteristic is all known to a person skilled in the art technology.
