Abstract
The utility model relates to a lead bracket and a flexible wire structure of a current mutual inductor which solves the defect that solid insulator of the existing dry type current mutual inductor is partially discharged and has the advantages of simple structure, convenient use as well as being capable of effectively solving the problem of partial discharging. The utility model is structured by being provided with at least one lead bracket matched with the shape of the current mutual inductor; at least one circle of flexible lead is arranged in the lead bracket; the lead bracket is matched with a secondary loop as well as a secondary lead bracket arranged outside the secondary lead and matched with the shape of the secondary loop in a perforating way.
Description
Technical field
The utility model relates to a kind of current transformer wire support and flexible cord structure of novel dry-type current transformer, especially solid insulation.
Background technology
That dry-type current transformer has is non-maintaining, do not have the no gas of oil, environment-protecting clean, in light weight, many advantages such as installation and transportation make things convenient for, it is that oil-immersed current transformer and gas insulated high voltage current transformer are unrivaled, meeting power department does not have the development trend of oiling, environmental protection, accepted by users in recent years, and spread all over whole electrical network rapidly.
At present, a lead of dry-type current transformer adopts copper strips or copper rod as carrying object more, and its outside insulating tape or semi-conductive tape of adopting is wrapped up, and makes it to become the resilient coating and the screen of carrying object.In fact, the microbubble of insulating material inside, micro-crack especially and the interfacial stress between unlike material, all may cause partial discharge quantity excessive.And the mode of wrapping itself just has irregular and inhomogeneities, and it can not shield the various defectives from material internal well, makes that solving the dry-type current transformer partial discharge quantity becomes a bottleneck.Office's problem of putting of present domestic dry-type current transformer product is not all solved well, operating current transformer, the inner this long-term partial discharge cumulative effect of its insulator, can cause insulating material aging rapidly, to such an extent as to reach puncture voltage, damage equipment also causes serious accident.
Summary of the invention
The purpose of this utility model is exactly in order to solve the defective that there is discharge dry-type current transformer solid insulator part, provide a kind of have simple in structure, easy to use, electric field is evenly distributed and realize buffering between the interface effectively, thereby reach current transformer wire support and the flexible cord structure that solves advantages such as partial discharge problem.
For achieving the above object, the utility model adopts following technical scheme:
A kind of current transformer wire support and flexible cord structure, it has at least one wire support that matches with the current transformer shape, is provided with at least one circle flexible conductor in wire support; Wire support cooperates with secondary coil and the outer secondary wire support punching that matches with the secondary coil shape of secondary coil.
Described flexible conductor and secondary coil are contained within respectively in wire support and the secondary wire support fully.
The method that the utility model has adopted wire support to combine with flexible conductor, and make secondary coil also be in the secondary wire support; Structurally, two wire supports have been used the notion of pictograph design, make stress distribution even, and shield effectiveness is remarkable.
The utility model changes traditional hard conductor (being copper strips or copper rod) into wire support and combines with flexible conductor, be in the wire support with seasonal secondary coil, and with wire support as screen, adopt the pictograph design, evenly stress distribution, shielded internal flaw effectively.
The beneficial effects of the utility model are: can solve the problem that there is discharge the inner part of solid insulating material up hill and dale, avoid the big serious consequence that may cause of dry-type current transformer partial discharge quantity of traditional structure, improved the reliability that dry-type current transformer uses.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Wherein, 1. wire support, 2. flexible conductor, 3. secondary coil, 4. secondary wire support.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Among Fig. 1, its wire support 1 of having at least one to match with the current transformer shape of novel dry-type current transformer carrying object is provided with at least one circle flexible conductor 2 in wire support 1; Wire support 1 cooperates with secondary coil 3 and secondary coil 3 outer secondary wire support 4 punchings that match with secondary coil 3 shapes.Described flexible conductor 2 and secondary coil 3 are contained within respectively in wire support 1 and the secondary wire support 4 fully.
Claims (2)
1, a kind of current transformer wire support and flexible cord structure is characterized in that: it has at least one wire support (1) that matches with the current transformer shape, is provided with at least one circle flexible conductor (2) in wire support (1); Wire support (1) cooperates with secondary coil (3) and outer secondary wire support (4) punching that matches with secondary coil (3) shape of secondary coil (3).
