Abstract

The utility model provides a welding table. The welding table comprises a handle provided with a heating core, a driving board driving the heating core, a control panel which controls the driving board to keep the temperature of the heating core stable and a transformer. The transformer is an annular transformer. Due to the adoption of the annular transformer with the conversion efficiency reaching up to 95%, the heating productivity of the welding table is smaller in the using process, and the full-load temperature is lower than 40 DEG C; the welding table saves more energy and is longer in service life.

A kind of welding stage

Technical field

The utility model relates to the parking stall measure system, particularly detects sky parking's parking stall measure system of mobile parking space information in sky parking.

Background technology

Welding stage is a kind of hand-operated tools that is usually used in electronic welding technique, by giving scolder (typically referring to the tin silk) heat supply, makes its fusing, thereby two workpiece are welded.Welding stage comprises the handle be comprised of solder horn, heat generating core and insulating materials, for heat generating core provides the drive plate of power supply, the control panel that the temperature of solder horn and heat generating core is controlled.Compare with common electric iron, there are following characteristics:

1, relatively, the efficiency of constant-temperature soldering station is relatively high for efficiency, and the thermal efficiency can reach 80% left and right, and electric iron generally can only have 50%;

2, relatively, the constant-temperature soldering station energy consumption is lower for energy consumption, because to the temperature regulated, is not just heating, and corresponding energy consumption is lower, that is to say, and same welding effect, the welding stage electricity consumption is less;

3, the comparison of rising again, the speed of rising again of welding stage, corresponding workman's operating efficiency is higher;

4, the consumptive material life-span compares, and the temperature of welding stage is controlled, can infinitely not raise, so the life-span of solder horn and the life-span of heat generating core are higher;

5,, the handle voltage of welding stage only has 24 volts of interchange to safety ratio, belongs to safe voltage, generally not there will be the electric shock phenomenon;

6, relatively, welding stage has function of eliminating static to antistatic, but electric iron does not generally have.

But existing welding stage user shape transformer, and the conversion efficiency of square transformer also has the space of lifting.

The utility model content

The purpose of this utility model is for above-mentioned defect, and a kind of welding stage is provided, and this candlestick uses toroidal transformer.

The technical solution of the utility model is: a kind of welding stage, comprise the handle with heat generating core, drive the drive plate of described heat generating core, described drive plate is controlled to the temperature that makes heat generating core and keep stable control panel, transformer, described transformer is toroidal transformer.

Described toroidal transformer converts civil power to two kinds of voltages and is linked into respectively described drive plate and control panel.
