Abstract
The utility model relates to the field of current transformers, in particular to a backbone type current transformer with a sensor. The backbone type current transformer is in an integrated structure formed by an iron core, a primary winding, a secondary winding, a primary terminal and a second terminal table in a vacuum cast manner through epoxy resin. The integrated structure is integrally mounted on a panel base with a mounting hole. An electric sensor capacitance voltage dividing device in U-shaped structure is arranged in the integrated structure and uniformly distributed outside the primary winding at an equal interval. A signal terminal of the electric sensor capacitance voltage dividing device and a secondary terminal are jointly led out to be cast on the second terminal table. The backbone type current transformer with the sensor has the advantages of an electrifying displaying function, signal sensitiveness and stability, compact structure, convenience to mount-, safety, reliability and insulation stability.
Description
Technical field
The utility model relates to the current transformer field, a kind of specifically belt sensor support type current transformer.
Background technology
10KV-35KV is metal enclosed/the metal armouring switch cubicle in, support type current transformer is to use as current measurement, electric energy metrical or relaying protection, simultaneously the also function of double as busbar pillar; Electrified sensor matches with electrification display whether the equipment of working voltage is arranged as the monitoring equipment device, and being both also is the insulation column effect as switch cubicle mesohigh busbar; These two kinds of critical pieces are two kinds of different stand-alone product versions in the existing switch cubicle, are distributed in different positions respectively according to the switch cubicle designing requirement; And along with the continuous release and the specification requirement of novel switched cabinet; The special miniaturization of pursuing switch cubicle, modularization, functionalization, high-protection level, performance such as easy for installation; The switch cubicle industry need a kind ofly collect support type current transformer especially, the electrification in high voltage transducer is the product of one, promotes the technical equipment of switch cubicle on the whole.
The utility model content
In order to satisfy novel metal sealing/metal armouring switch cubicle needs; Realize the miniaturization, modularization, functionalization, high-protection level of switch cubicle, characteristics such as easy for installation, the utility model provides a kind of be sensitive stable, the compact conformation of the charged display function, the signal that adopt the epoxide resin vacuum cast to form, easy for installation, safe and reliable, belt sensor support type current transformer that insulation is stable.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: a kind of belt sensor support type current transformer; By iron core, winding, secondary winding, primary connection terminal, secondary connection platform through the epoxide resin vacuum formula structure that pours into an integrated entity; This integral structure integral installation is on the flat base that has installing hole; Said integral structure inside is provided with electrified sensor capacitance partial pressure device; The electrified sensor device is the U-shaped structure, evenly equidistantly distributes in the outside of a winding, and the signal terminal of electrified sensor device and secondary connection terminal are drawn jointly and be cast on the secondary connection platform.
The cross-sectional width of said electrified sensor device is greater than the thick section of a winding.
Said primary connection terminal is for embedding the flat terminal block with threaded hole that pour mass and part expose.
Said integral structure bottom is provided with recessed square full skirt near base position.
The utlity model has following advantage:
1, charged display function, signal sensitivity are stablized: be provided with electrified sensor capacitance partial pressure device near the inner winding of integral structure; The structural design of optimizing; Assurance has enough design capacitance and induced voltage signal; Combine to make product to have charged display function with electrification display, accurately sensitivity display device on high-tension side electriferous state of when operation stably.
2, compact conformation, easy for installation: product reasonably is made of one the formula structure with electrified sensor and column support type instrument transformer; The inner space of the column support type instrument transformer that effectively utilizes; Product structure is compact more, and it is simultaneously easier for installation quick that the intensification design guarantees to have multinomial function.
3, safe and reliable, insulation is stablized: electrified sensor capacitance partial pressure device adopts epoxy resin to be enclosed in admittedly with a winding, the secondary winding of current transformer jointly; Assurance has electric insulation intensity preferably; Simplified split type in the past a plurality of element mounting means, move more safe and reliable, the recessed square full skirt of integral structure bottom design; Further strengthen outside high voltage electric field creepage distance over the ground, increased the insulation level of product.
