Abstract
The utility model discloses a transformer foundation fixation structure which comprises a foundation pre-embedded steel plate and a foundation welding steel plate connected with thereof; the foundation welding steel plate is connected with threaded structural components; and a transformer base is coupled and fixed with a concrete foundation through the threaded structural components. The transformer foundation fixation structure is characterized in that the threaded structural components comprise a screw rod and a screw nut; and one end of the screw rod and the foundation welding steel plate are connected into a rigid integral body. The utility model can ensure that the transformer can withstand external force and vibration trial in the operation, and also has the advantages of simple manufacture, convenient use and low cost at the same time.
Description
Technical field
The utility model relates to a kind of transformer foundation fixed structure.
Background technology
Along with the enhancing of human environmental consciousness, the technical advance of transformer not only is embodied on its basic parameter index, and its noise, vibration performance also are important indicators.And in decision transformer noise, vibration performance all multifactor, the transformer bottom is very important with the basic fixed mode.Transformer in service the effect of earthquake, wind surface active force, the vibration force of product itself that may be subjected to etc.Fixed structure will guarantee that the transformer body does not produce displacement with respect to the basis under the effect of above-mentioned various power, guarantees the reliability of products energy.
The transformer body location structure that present each transformer manufactory at home generally adopts is generally transformer integral body and directly drops on the basic plane through bottom bracket, uses bolt between bottom and the basis.As shown in Figure 1.Displacement that vibration produces when this structure can be avoided owing to the transformer operation, but through practice, this fixed form is after transformer is transported to the user installation scene, when the transformer base is connected with bolt with the basis, fixing screw thread is screwed into the degree of depth and is difficult to put in place fully, and stressing conditions is bad, bad mechanical strength, and transformer when operation bolt and soleplate junction screw thread easy-to-rust, fragile influence the overall performance of power transformer product.Transformer is constituted a threat to, cause transformer to owe firm in when operation and basic fixed.
Summary of the invention
The purpose of this utility model provides and a kind ofly can guarantee that screw thread is screwed into the degree of depth, stressing conditions is good, the transformer foundation safety fixed structure that mechanical strength is high.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of transformer foundation fixed structure, comprise basic pre-embedded steel slab and connected basic welding steel, this basis welding steel is connected with helicitic texture spare, transformer base and concrete foundation connect fixing by described helicitic texture spare, it is characterized in that, described helicitic texture spare comprises screw rod and the nut that is connected with the one end, and the screw rod other end and basic welding steel are linked as rigid unitary.
In the such scheme, it is to be screwed into earlier in the screwed hole of basic welding steel by screw rod that the described screw rod other end and basic welding steel are linked as rigid unitary, and dead in the weldering of the basic welding steel back side, again with basic welding steel and the welding of basic pre-embedded steel slab.Described nut comprises a thin nut and a high nut.
The utility model can guarantee that transformer is able to take external force and operating vibration test, and it is simple that the utility model also has manufacturing simultaneously, advantage easy to use and with low cost.
Description of drawings
Fig. 1 is existing transformer foundation fixed structure.Among Fig. 1: 1, bolt; 2, butterfly spring; 3, packing ring; 4, basic welding steel; 5, transformer base plane; 6, concrete foundation face; 7, basic pre-embedded steel slab.
Fig. 2 is the utility model transformer foundation fixed structure.Among Fig. 2: 8, thin nut; 9, high nut; 10, screw rod.
Fig. 3 is screw rod and the basic welding steel connection diagram among Fig. 2.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As Fig. 2, shown in Figure 3, the utility model changes the bolt 1 of Fig. 1 into screw rod 10, earlier the one end is screwed in the tapped through hole of basic welding steel 4, and in basic welding steel 4 back sides welding fixed (Fig. 3), making it becomes a rigid unitary with basic welding steel 4, to weld the basic welding steel 4 and basic pre-embedded steel slab 7 welding of screw rod 10 again, last transformer base is connected and fixed by screw rod 10 and double nut (high nut 9, thin nut 8) with the basis.
The utility model is screwed into screw rod 10 earlier in the screwed hole of basic welding steel 4, and the back side is welded into a rigid unitary, acts on the stress of weld seam and bolt by accounting, guarantees to have bigger design safety nargin.With double nut that transformer base and basis is effectively fixing again, reduce vibration and noise.Shock resistance is improved, simply firm, be easy to install.Bolt and threaded engagement controllable size during installation, quality easily guarantees.Can effectively reduce the vibration and the noise of transformer by these measures, guarantee the safe and reliable operation of product.
Claims (3)
