Abstract
The utility model discloses a generator neutral point CT support new construction mainly comprises base (1), backing plate (2) and backup pad (3), the one side and base (1) the fixed connection of backing plate (2), another side and backup pad (3) fixed connection, backup pad (3) be equipped with bolt hole (4) to the top edge of backup pad (3) is higher than base (1). The utility model discloses the problem that traditional support caused current transformer to damage can effectively be eliminated in simple structure, easy execution, with low costs, prolongs current transformer's life.
Description
Technical field
The utility model relates to a kind of CT bearing, has been specifically related to a kind of generator neutral point CT bearing new construction in electric power system application.
Background technology
In order to protect the safe and stable operation of high-rating generator, needing to configure perfect protection equipment for generator, just at generator neutral point place, current transformer must be installed for this reason.For the sake of security, instrument transformer is generally all rack-mount.Traditional transducer bracket is generally make of pure aluminum plate, aluminium sheet does camber, then with two obliquely the bolt of 45 ° instrument transformer is fixed, bolt bears the weight of certain instrument transformer body, so due to bolt strained unequal factor impact, often occur that instrument transformer occurs crackle at bolt fixed position, cause instrument transformer to damage or shorten the life-span.
For this reason, people take some ways and solve this problem.Carrying bolt is become large by some employings, to reduce unit lifting surface area.But effect is all not obvious, do not deal with problems at all.
Summary of the invention
The purpose of this utility model is for existing equipment Problems existing, provides a kind of structure and simply, easily implements, and effectively can solve the CT bearing new construction that support place of generator neutral point current transformer damages.
To achieve these goals, the utility model have employed following technical scheme:
A kind of generator neutral point CT bearing new construction, is formed primarily of base, backing plate and supporting bracket; The one side of described backing plate is fixedly connected with base, and another side is fixedly connected with supporting bracket; Described supporting bracket is provided with bolt hole, and the top edge of supporting bracket is higher than base.
In the utility model, current transformer is placed on bearing, weight is all born by base, then adopt, in base both sides, supporting bracket is set at CT transversely fixation of C T, change tradition by two modes that 45° angle bolt is fixing obliquely, so both can carry out current transformer good fixing, and also be unlikely to current transformer is damaged because weight is born by base simultaneously.
Further illustrate as of the present utility model, described welding with backing is connected on the side of base, and supporting bracket is welded on backing plate.Welding manner is more simple and reliable.
Further illustrate as of the present utility model, described bolt hole is oval bolt hole, or is circular internal thread hole.Adopt oval bolt hole, be also just applicable to using oval set bolt, can prevent from making set bolt rotate when rocking before and after CT and then occurring the phenomenon that CT laterally loosens.
Further illustrate as of the present utility model, after base places current transformer, the central spot of described bolt hole is on the cross central line of current transformer.CT laterally 180 ° are fixed, and set bolt is simply stressed, and fixed effect is better.
Operation principle of the present utility model:
Under well-known same pressure, the larger pressure of area is less, p=F/S, and namely pressure and lifting surface area are inversely proportional to.In other words, under uniform pressure, area is larger, then pressure is less.We utilize the technological transformation increasing instrument transformer lifting surface area and carry out with this principle reducing pressure, achieve good effect.
Compared with prior art, the beneficial effect that possesses of the utility model:
The utility model structure is simple, easily implement, cheap, adopt at base both sides extension supporting plate, being transversely fixed it at current transformer, effectively can eliminate the problem that traditional bearing causes current transformer to damage, and extends the useful life of current transformer.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is the end view of the utility model one embodiment.
Reference numeral: 1-base, 2-backing plate, 3-supporting bracket, 4-bolt hole.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment 1:
As shown in Figure 1-2, a kind of generator neutral point CT bearing new construction, is formed primarily of base 1, backing plate 2 and supporting bracket 3; The one side of described backing plate 2 is fixedly connected with base 1, and another side is fixedly connected with supporting bracket 3; Described supporting bracket 3 is provided with bolt hole 4, and the top edge of supporting bracket 3 is higher than base 1.Described backing plate 2 is welded on the side of base 1, and supporting bracket 3 is welded on backing plate 2.Described bolt hole 4 is oval bolt hole.After base 1 places current transformer, the central spot of described bolt hole 4 is on the cross central line of current transformer.
Embodiment 2:
A kind of generator neutral point CT bearing new construction, is formed primarily of base 1, backing plate 2 and supporting bracket 3; The one side of described backing plate 2 is fixedly connected with base 1, and another side is fixedly connected with supporting bracket 3; Described supporting bracket 3 is provided with bolt hole 4, and the top edge of supporting bracket 3 is higher than base 1.Described bolt hole 4 is circular internal thread hole.After base 1 places current transformer, the central spot of described bolt hole 4 is on the cross central line of current transformer.
Described base 1, connected mode between backing plate 2 and supporting bracket 3 adopt riveted joint.
