Abstract
The utility model relates to a current mutual inductor which comprises a mutual inductor main body composed of an induction iron core, a coil and a frame. At least two rows of binding posts and nameplate installation grooves are arranged on the mutual inductor main body. Nameplates are installed in the nameplate installation grooves which are installed between two adjacent binding posts. The current mutual inductor is simple in structure, convenient to install, firm in nameplate installation, pleasant and elegant in appearance of a product, stable in performance, good in economic and social benefits and high in practicality and can effectively reduce maintaining cost, reduce labor intensity of workers and comply with environment-protection standards.
Description
Technical field
The utility model relates to a kind of current transformer.
Background technology
Current transformer is the big electric current of the main circuit crossed according to flow measurement; induce the little electric current of certain ratio at secondary side; realize the electric device of measurement and relaying protection for instrument; at current transformer indication plate is set; the important technological parameters such as electric current no-load voltage ratio that show this device are for correctly installing and using.This series products adopts viscose glue bonding mostly, and this connected mode is unreliable, peels off easily.Therefore, be necessary existing connected mode is optimized.
Summary of the invention
The utility model easily peels off at indication plate in the prior art, and making the shortcoming that replacement cost is higher provides a kind of simple in structure, easy for installation, and the current transformer of firm and reliable connection is installed.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Current transformer, comprise the current transformer body of being formed by inductive iron core, coil and framework, current transformer body is provided with at least two row's binding post and indication plate mounting grooves, in the indication plate mounting groove indication plate is set, and described indication plate mounting groove is installed between adjacent two binding posts.Can carry out wiring according to indication plate during installation, guarantee that the wiring of instrument transformer accurately reaches output accurately, effectively avoid wiring error or unclear trouble and the loss that brings.
As preferably, the outward flange of described indication plate is provided with the fixed installation sheet, and described indication plate is fixed in the indication plate mounting groove by screw.
As preferably, the outward flange of described indication plate is provided with to the mounting bar of back bending, and described mounting bar is plugged in the indication plate mounting groove, and indication plate mounting groove groove bottom is close at the indication plate back, and mounting bar and indication plate mounting groove are connected as a single entity.
As preferably, the cell body shape of described indication plate mounting groove and the shape of indication plate are complementary, and the degree of depth of described indication plate mounting groove is 1-5mm.
The utility model has significant technique effect owing to adopted above technical scheme:
The utility model is simple in structure, and is easy for installation, and indication plate is installed firmly, effectively reduces maintenance cost, reduced working strength of workers, and product design is elegant in appearance, and stable performance and compliance with environmental protection requirements have very high economic and social benefits, the practicality height.
No matter the utility model product still can both satisfy client's demand from the installation aspect from the quality aspect, all bring very large convenience to the client from economy and time aspect simultaneously, avoid the client to the replacing of power equipment, guarantee is provided for the fail safe of power equipment.
