Description

A kind of current transformer measures frock
Technical field
This utility model is related to a kind of measurement servicing unit, and in particular to a kind of current transformer measures frock.
Background technology
As power system develops to high-voltage large current direction, New Generation of Intelligent transformer station further promotes and builds If optical fiber current mutual inductor technology is developing progressively ripe.At present at home, the producer for having had part has passed through national optical fiber electricity The technical appraisement of current transformer, and it is provided with certain mass production capabilities.But optical fiber current mutual inductor is surveyed in larger current There is in terms of amount certain inconvenience.Because all-fiber current transformator measurement range is wide, it is measurement transformer in the case of high current Accuracy, it is often necessary to high current, such as 800A, 1200A etc..The problems such as by current feedback circuit, conductor impedance, is affected, greatly Current feedback circuit often can not provide the high current of such intensity for a long time, thus in actual application, it is commonly used logical The wire of too little current comes and goes winding to form high current.In different tests, the wire of winding passes through transformer center every time The position (i.e. concentricity) in hole and the sense of current all can be different, and this will in the calibration and measurement of optical fiber current mutual inductor Certain deviation can be produced.
Utility model content
For the problems referred to above, this utility model provides one kind guarantees that during different tests wire passes through transformer position Repeatability, guarantee that wire concentricity and the conforming current transformer of the sense of current measure frock.
To solve the above problems, the technical scheme that this utility model is taken is:A kind of current transformer measures frock, including Base and connected support, the support are in tabular, and carriage center opens up some wire fixing holes, in support side Face, some sensing ring fixing slots are offered around wire fixing hole.
Heart position opens up wire fixing hole in the bracket, and the wire fixing hole size is matched with wire thickness, to ensure Wire is passed through in the center of sensing head, it is ensured that wire concentricity.In experiment, each hole can be numbered, be remembered if necessary Numbering of the lower wire through hole, it is ensured that carry out the repeatability of different tests every time.Sensing ring is opened up around wire fixing hole Fixing slot, sensing ring fixing slot are corresponding with sensing ring fixed hole position, to fixed sensing head, the sensing ring fixing slot It is suitable for different inner diameters, the sensing head of different fixed hole positions.
Preferably, the support is installed on base by fixed mount.The fixed mount adopts aluminum alloy materials, and structure is tight Gu, and lighter weight, it is ensured that base and support be completely embedded, solid and reliable.
Preferably, the fixed mount is the L-shaped connecting plate being made up of horizontal plate and vertical plate, the vertical plate and horizontal plate First through hole is offered, the second through hole coordinated with first through hole on the support and base, is equipped with.Can be in first through hole Be fixedly connected with hex(agonal)screw being penetrated in the second through hole, ease of assembly, disassemble and transport.
Preferably, the side face uniformly offer four sensing ring fixing slots, neighboring sensor ring fixing slot it Between be in 90 degree of angles.Using long bolt through sensing ring fixing hole and aforementioned four sensing ring fixing slot, it can be ensured that structure is solid It is fixed firm.If disposable need the more multiple sensing heads of fixation, two groups of frocks are may be selected, sensing head are clipped in the middle of two pieces of supports, To keep screw rod uniform force, transducing head structure is firm.
Preferably, the support and base are made using expoxy glass plank.Expoxy glass board surface is smooth not to have hair Thorn, surrounding corner angle carry out rounding operation, it is to avoid the damage in test, transportation to optical fiber, transformer and personnel;Simultaneously Expoxy glass plank insulant preferably, it is to avoid produce with conductive contact in process of the test dangerous.
This utility model is not limited to all-fiber current transformator, can be applicable to the current transformer of various other forms, Include but are not limited to:The current transformers such as Luo-coil, flexibility.
This utility model simple structure, easy to process, lightweight, low cost, it is convenient to produce manufacture in enormous quantities.For optical fiber electricity The test of current transformer, calibration, measurement provide reliable solution, solve wire with different angles, diverse location Through the measured deviation problem that (concentricity) during optical fiber current mutual inductor causes, it is ensured that accuracy of measurement.

Specific embodiment
It is understandable to enable above-mentioned purpose of the present utility model, feature and advantage to become apparent from, with reference to being embodied as Scheme is further described to this utility model:
A kind of current transformer measures frock, as shown in Figures 1 to 4, including what is be made using expoxy glass plank Base 1, support 2 and fixed mount 3 between the two is connected to, the support 1 is in tabular, carriage center opens up some wires Fixing hole 4, in support one side, uniformly offers four sensing ring fixing slots 5, neighboring sensor ring around wire fixing hole It is in 90 degree of angles between fixing slot 5.The fixed mount 3 is the L-shaped connecting plate being made up of horizontal plate and vertical plate, described vertical Plate and horizontal plate offer first through hole 6, and the second through hole coordinated with first through hole 6 is equipped with the support 2 and base 1 7。
Which uses process as follows:
Step one:Structure used by processing the frock first, is to ensure its structural strength and insulating properties, using expoxy glass Plank makes support 2 and base 1, and through hole and hole slot are processed on tram;The positions such as the corner angle and through hole (groove) to structure Carry out chamfering or polishing, it is desirable to which Glabrous are pierced.
Step 2:Will be first through hole in structure 6, the second through hole 7 fixed using soket head cap screw, it is assembled into and is available for examination The frock form tested.
Step 3:Head fixed hole position will be passed to match with support sensing ring fixing slot 5, passed through with stay bolt and fixed, really Wire fixing hole 4 is protected in the center of sensing head, and sensing head is fixed.
Step 4:Wire is penetrated in wire fixing hole 4, is the measurement high current in the case of small current can only be provided Accuracy, same wire is often repeatedly passed through sensing head, winds a few to obtain high current, therefore to ensure experiment Wire guide can be numbered by repeatability, record the numbering that the wire through wire fixes 4, to guarantee in process of the test The environment concordance that next time, test was tested with this.
Step 5:In wire, in addition certain electric current, carries out sensing head precision, accuracy measurement.
Finally it should be noted that:Above example is only to illustrate the technical solution of the utility model rather than which is limited System, although being described in detail to this utility model with reference to above-described embodiment, those of ordinary skill in the art should Understand:Still specific embodiment of the present utility model can be modified or equivalent, and it is new without departing from this practicality Any modification of type spirit and scope or equivalent, which all should be covered in the middle of right of the present utility model.
