Since the two E-shaped magnetic cores are aligned to each other, the central posts of the two E-shaped magnetic cores are flattened, and when the converter inductor is in the working condition, the problems of large heat generation, difficult emission and easy burning of the converter inductor are solved.
Description
Technical field
The utility model relates to change of current inductance, mainly is meant in the inverter type welder soft switch device, is connected in parallel on the main transformer change of current inductance at utmost point two ends just.
Background technology
Actual demand directly promotes the continuous development and progress of power technology, for energy-conservation, stable, working life, the green energy resourceization that improves inverter, using novel topological circuit is no-voltage, zero current turning-on and off state to realize that power switch component turns on and off, reducing the switch stress of power electronic element, is the main direction of present power supply research.(detect automatically and show electric current; and when taking place, harm situations such as overcurrent, overvoltage have automatic protection functions and a more senior Based Intelligent Control; power technology with sensing detection, sense samples, sensing protection gradually becomes trend, and the transducer that detects curtage just arises at the historic moment and begins to be subjected to vast power supply designer's favor in China.) change of current inductance is used for finite both inverter bridge circuit, the output that mainly acts on inverter type welder is controlled by PWM, when switch turn-offs, because change of current inductance constitutes resonant tank with the blocking capacitor device, for electronic switch is created the condition that no-voltage is opened; When leading arm switch was opened, it is in parallel that inductance and transformer are once surveyed, and obtains energy and realize energy storage.Because the operating frequency height of this inductance, magnetic flux change is big, again owing to cost and bulk factor, requires to adopt the magnetic core of opening air gap.
Known technology is that the center pillar (between a magnetic core) of the change of current inductance made of " E " type magnetic core has air gap, and both sides magnetic core air gap is located with aluminium flake, and its shortcoming is: when welding machine move, because the existence of air gap and aluminium flake, heating and was difficult for distributing greatly.
The utility model content
Technical problem to be solved in the utility model provides a kind of change of current inductance, solves the heating of change of current inductance greatly, is difficult for distributing the problem of change of current inductance easy burn-out.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of change of current inductance, comprise two E type magnetic cores, the glue core of hollow, lead-in wire, induction coil, described induction coil is enclosed within on the glue core, described two E type magnetic cores are relative is located at the glue in-core, described lead-in wire is fixed on the glue core, and described induction coil is provided with two-layer insulating tape outward; Described E type magnetic core is a ferrite, comprises the side column and the middle newel at two ends, and described side column is shorter in length than newel, and the newel of the E type magnetic core that glue in-core two is placed relatively develops mutually, is provided with the gap between the side column.Because two E type magnetic cores align, and the newel of two E type magnetic cores is developed, during change of current inductance operating state, solve the heating of change of current inductance greatly, be difficult for distributing the problem of easy burn-out.
As improvement, be provided with epoxy resin between the side column of the E type magnetic core that described glue in-core two is placed relatively.
As improvement, described induction coil is entwined by silk-covered wire.
As improvement, described lead-in wire is located in the fiber sleeve, and described sleeve pipe two ends are provided with the pipe box head, and the lead-in wire two ends are provided with the line ear, outside described line ear protruded tube is pullover.
The beneficial effect that the utility model is compared with prior art brought is:
Manufacturing process is simple, easy for installation, parameter consistency is good; Because two E type magnetic cores align, and the newel of two E type magnetic cores is developed, during change of current inductance operating state, solve the heating of change of current inductance greatly, be difficult for distributing the problem of easy burn-out.
