Abstract

The utility model relates to a rod-shaped direct-current reactor iron core. According to the technical scheme provided by the utility model, the rod-shaped direct-current reactor iron core is characterized in that the reactor iron core is in a rod-shaped structure and is made of an electrical pure iron material. Since the reactor iron core provided by the utility model is made of the electric pure iron material, the production cost of the reactor can be greatly reduced and the market competitiveness of enterprises is improved.

Description

Bar-shaped direct current reactor iron core

Technical field

The utility model relates to the appurtenances of welding machine, specifically is a kind of bar-shaped direct current reactor iron core.

Background technology

Reactor can improve the dynamic characteristic of DC power supply, the rate of climb of limiting short-circuit current and the peak value of short circuit current, and striking performance and the minimizing of regulating welding machine are splashed.The iron core of existing transformer, reactor and generator mainly is to adopt silicon steel sheet to form; Because the price comparison of silicon steel sheet is expensive; Cause the cost of core of reactor high, the production cost that reduces reactor is most important for the market competitiveness that strengthens enterprise.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of bar-shaped direct current reactor iron core is provided, and it adopts the electrical pure iron material, can reduce the production cost of reactor greatly, improves the market competitiveness of enterprise.

The technical scheme that provides according to the utility model: bar-shaped direct current reactor iron core is characterized in that: this core of reactor is a club shaped structure, adopts the electrical pure iron material to process.

For the out put reactor of welding machine the inside, having much all is to adopt bar-shaped mechanism, and this iron core does not have closed magnetic circuit; Can be unsaturated yet; Logical is again direct current, so eddy current neither be very big, complete available electrical pure iron replaces silicon steel sheet; Through actual use for many years, its main welding performance can compare favourably with the traditional silicon steel sheet iron core fully.

As the further improvement of the utility model, said core of reactor is welded by the stack of multilayer electrical pure iron sheet or directly is made into integration by the electrical pure iron material.

As the further improvement of the utility model, the cross sectional shape of said core of reactor is rectangle or circle.

The cross section by the purpose of electrical pure iron direct current reactor iron core invention be: reduce cost, enhance one's market competitiveness.

The utility model compared with prior art, advantage is: the core of reactor of the utility model adopts the electrical pure iron material to process, and can reduce the production cost of reactor greatly, improves the market competitiveness of enterprise.

Embodiment

Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.

Embodiment 1

As shown in Figure 1, the bar-shaped direct current reactor iron core among the embodiment 1 is welded by 1 stack of multilayer electrical pure iron sheet, and its cross sectional shape is a rectangle.

Embodiment 2

Like Fig. 2, shown in Figure 3, the bar-shaped direct current reactor iron core among the embodiment 2 is welded by 1 stack of multilayer electrical pure iron sheet, and its cross sectional shape is circular.

Embodiment 3

As shown in Figure 3, the bar-shaped direct current reactor iron core among the embodiment 3 directly is made into integration by the electrical pure iron material, and its cross sectional shape is circular; All the other embodiment 2 compare; Guaranteeing that under the identical situation of sectional area, the coiling radius can be littler, can economize copper (aluminium) line of coil.
