Abstract
The invention discloses a laminated riveting block-shaped current transformer. The current transformer comprises a block-shaped alloy body, the block-shaped alloy body is mounted in a frame, and an air gap is reserved between the block-shaped alloy body and the frame. The current transformer further comprises pins used as the tail ends of the current transformer and wire ends used as the primary input ends of the current transformer, the pins are connected to the block-shaped alloy body and stretch out of the frame, and the wire ends are wound on the block-shaped alloy body. The block-shaped alloy body is made of permalloy and is machined in a laminated riveting mode. The current transformer is simple in design, small in size, high in environmental suitability, reliable in safety performance, and suitable for various using occasions.
Description
Technical field
The present invention relates to current transformer, be specifically related to the block type current transformer of a kind of folded riveting.
Background technology
Current transformer principle is according to electromagnetic induction principle.Current transformer is made up of the iron core closed and winding.Its first side winding number of turn is little; go here and there in the circuit needing the electric current measured; therefore it often has whole electric currents of circuit to flow through; secondary side winding turn ratio is more; be serially connected in measuring instrument and protective loop, operationally, its secondary side circuit is closed to current transformer all the time; therefore the impedance of measuring instrument and protective loop series coil is very little, and the operating state of current transformer is close to short circuit.Current transformer is that primary side big current is converted to secondary side small area analysis to use, and secondary side can not be opened a way.Inconvenience installed by current transformer of the prior art, and environmental suitability is poor, and stability is not high.
Summary of the invention
In order to solve problems of the prior art, the invention discloses the block current transformer of a kind of folded riveting.
Technical scheme of the present invention is as follows:
The block type current transformer of a kind of folded riveting, comprises bulk alloy, described bulk alloy is arranged within framework, leave air gap within described bulk alloy and described framework; Also comprise as the pin of current transformer tail end and the conductor wire end as current transformer primary input terminal; Described pin to be connected on described bulk alloy and to stretch out outside framework; Described conductor wire end is wrapped on described bulk alloy; The material of described bulk alloy is permalloy, is processed by the form of folded riveting.
Advantageous Effects of the present invention is:
The design of this current transformer is succinct, volume is little, environmental suitability is strong, and security performance is reliable, can meet various use occasion, mainly be applicable to the measurement of electrical network, controls.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Fig. 1 is schematic diagram of the present invention.The present invention includes and comprise bulk alloy 1, bulk alloy 1 is arranged within framework 2, leaves air gap 3 between bulk alloy 1 and framework 2; Also comprise the pin 4 as current transformer tail end and the conductor wire end 5 as current transformer primary input terminal; Pin 4 to be connected on bulk alloy 1 and to stretch out outside framework 2; Conductor wire end 5 is wrapped on bulk alloy 1; The material of bulk alloy 1 is permalloy, is processed by the form of folded riveting.
Current transformer of the present invention adopts the permalloy of nickel content 78-80%, and permalloy is in fact iron nickel (FeNi) alloy, and its coercive force is very low, and saturation magnetic induction Bs, magnetic permeability and Curie temperature are all very high, close to pure iron.Polynary permalloy, initial relative permeability can reach 30000 ~ 80000, but resistivity is low, can be used on the operating frequency up to (20 ~ 30) kHz, permalloy loss ratio is lower, and particularly environmental suitability is relatively good, stable performance, although price, be still used in the stricter power supply of condition.
Bulk alloy 1 of the present invention is after processing, carries out the processing of folded riveting formula, as required nickel steel piece is processed into different bulks, the position of air gap 3 and air gap 3, all can regulate, easy for installation, peripheral fixing with framework.
Above-described is only the preferred embodiment of the present invention, the invention is not restricted to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive without departing from the spirit and concept in the present invention or associate, all should think and be included within protection scope of the present invention.
