Abstract
The utility model aims at providing an electric reactor used for a frequency converter, which endures low temperature, resists shock, has high intensity and leads good insulating property. The aim is realized in such a manner that the electric reactor is composed of a base assembly, a winding and an installation assembly. The installation assembly is connected with the base assembly, and the base assembly is connected with the winding. The electric reactor used for an air-conditioning inverter has the characteristics that: the thermal expansion coefficient of a winding copper wire of the electric reactor is basically in accordance with that of insulating material of a shell, so as to ensure the adaptability of the electric reactor against high and low temperature. With the characteristics of good insulating property, high intensity, low-temperature endurance and shock resistance, the electric reactor is an ideal constituent component of the air-conditioning inverter.
Description
(1) technical field
The utility model relates to the electrotechnics power technology, is exactly a kind of reactor that is used for the air-conditioning inverter specifically.
(2) background technology
Along with the develop rapidly of power electronic technology, microelectric technique, new product, new technology emerge in an endless stream.Wherein represent the frequency converter of modern electronic technology development level, be widely used in electric drive and the automation equipment, they have excellent control characteristic and strong robustness, defencive function and electricity-saving function.The reactor that is used for railway motor train unit frequency converter is from external import, and reactor design environment temperature is+60 ℃--and 10 ℃.China is with a vast territory, and the four corners of the world temperature difference is big, and the northern lowest temperature in winter reaches-40 ℃.In such low temperature environment, the insulation that is installed in the frequency converter reactor of bottom, compartment is damaged easily, causes the frequency converter cisco unity malfunction, influences the operation of train air-conditioning system.
(3) summary of the invention
The purpose of this utility model is to provide the reactor that is used for frequency converter of a kind of low temperature resistant, antidetonation, intensity height, good insulation preformance.
The purpose of this utility model is achieved in that it is made up of base assembly 11, winding 2 and installation component 12.Installation component 12 connects base assembly 11, and base assembly 11 connects winding 2.
The utility model also has following technical characterictic:
(1) described base assembly 11 comprises base 1, lead terminal 3 and outlet terminal 4.Base 1 connects lead terminal 3, and lead terminal 3 connects outlet terminal 4.
(2) described winding 2 comprises that first winding 5 and second winding, 6, the first windings 5 connect second winding 6.
(3) described installation component 12 is made up of feet 7, mounting panel 8, insulating case 9 and construction bolt 10, and feet 7 connects insulating case 9, insulating case 9 connection plates 8,
Mounting panel 8 connection bolts 10.
A kind of reactor that is used for the air-conditioning inverter of the utility model, the thermal coefficient of expansion of its reactor winding copper cash and casing insulation material coefficient of thermal expansion coefficient basically identical have guaranteed the conformability of reactor to high low temperature.Reactor good insulation preformance, intensity height, low temperature resistant, shock resistance.It is the desirable building block of air-conditioning inverter.
(4) description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model.
(5) embodiment
The utility model is described in further detail for example below in conjunction with accompanying drawing.
The utlity model has that thermal coefficient of expansion is little, the cracking that prevents to insulate, can be in adverse circumstances the characteristics of reliably working, be a kind of template air core reactor, can be used for the inverter of bottom, railway motor train unit compartment aircondition.The utility model also has following technical characterictic:
(1) the insulation flange of four jiaos of described housings can make two fastening backs form ventilating air passages in the middle of two.
(2) fastening bolt can replace installing foundation bolt.
(3) described housing is by mould compression moulding.
(4) described winding is the disc coil that insulation multiply copper cash relies on line mould coiled.
(5) described binding post is that coil is started to cold pressing with Wiring nose with intact head and is formed by connecting, and outlet terminal is with two groups of coils from parallel connection of coils.
(6) reactor housing described in the utility model is that resin adds glass fibre, adds flexibilizer in resin, adjusts the fragility of solidfied material, improves the anti-cracking performance of insulation, impact strength, thermal shock resistance properties.Insert the viscosity that an amount of diluent can reduce resin significantly, be convenient to processing and forming.Curing agent adopts methylhexahydrophthalic anhydride, and the solidfied material that generates with this cured resin not only has good electrical insulation properties, and has good weatherability.This is typical outdoor resin formula (ambient temperature-35 ℃～+ 60 ℃).
(7) in resin, insert the coefficient of expansion, cure shrinkage, the curing reaction caloric value that a certain amount of filler can reduce resin, improve thermal conductivity, thermal endurance, hardness and the dimensional stability of material.Fiberfill can significantly improve mechanical strength.
