Abstract
The utility model relates to a tensioning screw rod assembly structure for an iron core reactor. The tensioning screw rod assembly structure comprises a tensioning screw rod, an upper metal clamp element, a lower metal clamp element, a screw nut and an insulation T-shaped pad, wherein the two ends of the tensioning screw rod are respectively connected with an upper metal clamp element and the lower metal clamping element, the upper end of the upper metal clamp element and the lower end of the lower metal clamp element are respectively provided with screw nuts, the insulation T-shaped pad is arranged between the lower metal clamp element and the tensioning screw rod, the top of the insulation T-shaped pad is positioned at the upper end of the lower metal clamp element, an insulation flat pad is arranged between the screw nut and the lower metal clamp element, an elastic pad is also arranged between the screw nut and the upper metal clamp element, and flat pads are arranged between the elastic pad and the upper metal clamp element as well as between the screw nut and the insulation flat pad. The tensioning screw rod assembly structure for the iron core reactor has the advantages that the structure position of the insulation T-shaped pad on the tensioning screw rod is changed, so the insulation T-shaped pad cannot bear the screwing tension, the crack phenomenon of the insulation T-shaped pad is avoided, and the reliability of products is ensured.
Description
Technical field
The utility model relates to a kind of stretching screw assembly structure, relates in particular to a kind of stretching screw assembly structure for iron-core reactor.
Background technology
Reactor also is inductor, will produce magnetic field in its occupied certain space scope during a conductor energising, so the electric conductor of all energy current-carrying has perception in general sense, yet the inductance of the long straight conductor of energising is less, the magnetic field that produces is not strong, therefore actual reactor is lead coiled solenoid form, claims air core reactor; Sometimes in order to allow this solenoid have bigger inductance, just insert iron core in solenoid, be called core type reactor, air core reactor generally is used for small-capacity product, and high-capacity reactor generally is iron-core reactor.
All design in the present core type reactor stretching screw is arranged, its effect on the one hand is to go up air gap and fitted position stable between lower yoke and stem when guaranteeing the reactor operation, is that the connecting assembly as whole reactor plays load-bearing and assembles fastening on the other hand; In use in order to reduce the stray loss of reactor as far as possible, should avoid allowing the metal folder of lower yoke form electromagnetism conducting loop with drawing screw rod, therefore, on the structural design of iron-core reactor, stretching screw and insulation cushion must be arranged between arbitrary metal folder up and down and the insulation of insulation T type pad separates (its structure as shown in Figure 1), but in use find, when stretching screw tightens to certain moment of torsion, and when not reaching the setting of moment of torsion as yet, cracked phenomenon can appear because pressure-bearing is excessive in insulation T type pad, make the stray loss of iron-core reactor increase, influenced the stability of iron-core reactor operation.
The utility model content
The utility model purpose is to provide a kind of T type pad of avoiding insulating cracked in order to overcome the deficiencies in the prior art, guarantee iron-core reactor stable iron-core reactor stretching screw assembly structure.
For achieving the above object, the technical solution adopted in the utility model is: a kind of iron-core reactor stretching screw assembly structure, comprise stretching screw, last metal folder, following metal folder, nut and insulation T type pad, described stretching screw two ends are connected with metal folder and following metal folder respectively, and the upper end of described upward metal folder and the lower end of following metal folder are respectively equipped with nut; Be provided with insulation T type pad between described metal folder down and the stretching screw; The top of described insulation T type pad is positioned at the upper end of metal folder down.
Preferably, be provided with the insulation plain cushion between described nut and the following metal folder.
Preferably, also be provided with the bullet pad between described nut and the last metal folder.
Preferably, between described bullet pad and the last metal folder, and be equipped with plain cushion between nut and the insulation plain cushion.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
A kind of iron-core reactor stretching screw assembly structure of the utility model scheme, insulation T type pad is between stretching screw and following metal folder, and the top of insulation T type pad is in the upper end of following metal folder, make insulation T type pad when stretching screw is stressed, can not bear like this and tighten pulling force, avoided insulation T type to get now cracked phenomenon discard, reduce the stray loss of iron-core reactor, guaranteed the stability of iron-core reactor operation.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation that the iron-core reactor of prior art is used the stretching screw assembly structure;
Accompanying drawing 2 is the structural representation that iron-core reactor of the present utility model is used the stretching screw assembly structure;
Wherein: 1, stretching screw; 2, nut; 3, go up the metal folder; 4, following metal folder; 5, insulation plain cushion; 6, insulation T type pad; 7, bullet pad; 8, plain cushion.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of iron-core reactor stretching screw assembly structure as shown in Figure 2, comprise stretching screw 1, last metal folder 3, following metal folder 4, nut 2 and insulation T type pad 6, described stretching screw 1 two ends are connected with metal folder 3 and following metal folder 4 respectively, and the upper end of described upward metal folder 3 and the lower end of following metal folder 4 are respectively equipped with nut 2; Be provided with insulation T type pad 6 between described metal folder 4 down and the stretching screw 1; The top of described insulation T type pad 6 is positioned at the upper end of metal folder 4 down; Be provided with insulation plain cushion 5 between described nut 2 and the following metal folder 4; Also be provided with bullet pad 7 between described nut 2 and the last metal folder 3; Between described bullet pad 7 and the last metal folder 3, and be equipped with plain cushion 8 between nut 2 and the insulation plain cushion 5.
A kind of iron-core reactor stretching screw assembly structure of the utility model scheme, insulation T type pad 6 is down between metal folder 4 and the stretching screw 1, and the top of insulation T type pad 6 is positioned at the upper end of metal folder 4 down, insulation T type pad 6 can not bear when stretching screw 2 is stressed and tighten pulling force like this, avoided insulation T type pad 6 cracked phenomenon to occur, reduce the stray loss of iron-core reactor, guaranteed the stability of iron-core reactor operation.
Below only be concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
