Abstract
The utility model discloses a shock-resistant dry-type transformer which comprises a transformer body. The transformer body comprises an upper clamping component and a base seat, wherein a transformer base is arranged on the base seat. Upper top beams are respectively arranged at two ends of the upper clamping component. The middle parts of the top beams are fixedly connected with the upper clamping component. A straining beam is arranged between the transformer base and each upper top beam. According to the scheme, a tightening fixed structure is added on the transformer body, supporting intensity of the transformer body is increased, and shock-resistant capacity of a transformer is improved, so that the shock-resistant requirements of nuclear power occasions to dry-type transformers are met.
Description
Technical field
The utility model belongs to transformer manufacture technology, especially relates to a kind of antidetonation formula dry-type transformer.
Background technology
Along with the development of society, human utilization to the energy has turned to development utilization to nuclear energy, wind energy, solar energy and biological energy source equal energy source gradually by traditional coal resources.Nuclear energy has obtained development fast with plurality of advantages such as safe, clean environment firendly and economy height.From the situation of China's development nuclear power, national investment strengthens gradually, in the developed area, and the first-selected nuclear power station of power plant construction.In the construction of nuclear power station, the nuclear power generating equipment production domesticization has obtained bigger progress.Nuclear power station 1E level dry-type transformer is power supply unit important in the nuclear power, and the anti-seismic performance to transformer in nuclear power station has proposed higher requirement, and transformer traditionally can not satisfy the requirement of the antidetonation of nuclear power station.
Summary of the invention
The purpose of this utility model is to provide a kind of antidetonation formula dry-type transformer, can solve nuclear power station use in to the problem of shock resistance specific (special) requirements.
For achieving the above object, the technical solution adopted in the utility model is: a kind of antidetonation formula dry-type transformer, comprise transformer body, this transformer body comprises upper clamping piece and base, it is characterized in that described base is provided with transformer base, described upper clamping piece two ends are respectively equipped with back timber, should go up back timber and fixedly connected with described upper clamping piece at the middle part, described transformer base and describedly be equipped with straining beam between the back timber on each.
Further, described pedestal is rectangular frame structure, and the length of described last back timber is less than the length on limit parallel with being somebody's turn to do last back timber length direction on the described rectangular frame structure; Described straining beam is 4, and the top of each straining beam is separately fixed at the both sides of back timber, fixedlys connected respectively with two limits in addition of described rectangular frame structure respectively in the bottom.
Further, described rectangular frame structure, straining beam and last back timber are the channel-section steel structure, and described straining beam is fixedlyed connected with rectangular frame structure by the reinforcement channel-section steel that is arranged on the rectangular frame structure.
Further, be fixedly connected by welding between described rectangular configuration and the straining beam and between straining beam and the last back timber.
The utility model is by the rectangular frame structure channel-section steel around increasing on one's body at transformer, the straining beam channel-section steel, and last back timber channel-section steel, make transformer when running into earthquake loading, vibration force has only a very little part to pass on one's body the device of dry-type transformer, and all the other all reach the last back timber channel-section steel of transformer and the folder at two ends, are discharged to the earth by straining beam channel-section steel and rectangular frame structure channel-section steel, this kind structure can reduce the amplitude of fluctuation of transformer in vibration processes, improves the shock resistance of transformer.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
As shown in Figure 1, a kind of antidetonation formula dry-type transformer of the present utility model, comprise transformer body 1, this transformer body 1 comprises upper clamping piece and base, base is provided with transformer base 2, the upper clamping piece two ends are respectively equipped with back timber 5, and back timber 5 is fixedlyed connected with described upper clamping piece at the middle part on this, described transformer base 2 and describedly be equipped with straining beam 4 between the back timber 5 on each.
As preferred version of the present utility model, described transformer base 2 is rectangular frame structure, the length of described last back timber 5 is less than the length on limit parallel with being somebody's turn to do last back timber 5 length directions on the described rectangular frame structure, described straining beam 4 is four, and its top is separately fixed at the both sides of back timber 5; Fixedly connected with two limits in addition of described rectangular frame structure respectively in the bottom.Rectangular frame structure, straining beam 4 and last back timber 5 are the square groove steel construction, and straining beam 4 is fixedlyed connected with rectangular frame structure by the reinforcement channel-section steel 3 that is arranged on the rectangular frame structure.In use, in order to improve anti seismic efficiency, fix by welding between described frame structure and the straining beam 4 and between straining beam 4 and the last back timber 5.
The utility model is by welding together the base of transformer body and the transformer base of rectangular frame structure, and two ends all are connected with straining beam by strengthening channel-section steel.One end of last back timber is connected with transformer, the side of the upper clamping piece of the other end and transformer body welds together, this design can not only play under earthquake loading, guarantees rigidity and the intensity of 1E level dry-type transformer, and the width of cloth that can bear transformer body is to power.Thereby increased the shock resistance of 1E level dry-type transformer.
