Abstract
The integral structure of welding power supply includes three layers, including upper layer with electric parts including control transformer and power device driving board, middle layer with cooling fan and radiator, lower layer with main transformer and reactor, and front control panel in the front of the welding power supply. The whole structure of the welding power supply can effectively prevent dust from influencing electrical components such as a main control P plate, a driving P plate of a power device, a display plate and the like in severe environment.
Description
Technical field
The utility model relates to a kind of overall structure of the source of welding current.
Background technology
The source of welding current in the past as shown in Figure 1, master control P plate is horizontally placed in the cavity of packing less upper strata, and the dust of power supply outside and metallic dust will be easy to produce on control P plate to be piled up, and causes short circuit between the pin such as IC, causes fault.
The utility model content
The purpose of this utility model solves the above problems exactly.
According to the utility model, the overall structure of the source of welding current is divided upper, middle and lower-ranking, wherein is adjacent to be provided with an independent annular seal space with preceding control panel in the middle level, vertically places master control P plate in it, in order to prevent entering of metallic dust, isolated the influence of pyrotoxin simultaneously.
Preferably, source of welding current upper strata is a sealed type, and the electrical part product such as driving P plate that can avoid being arranged in power device wherein like this are subjected to the invasion and attack of dust, thereby have improved reliability.
Description of drawings
Below in conjunction with drawings and Examples the utility model is elaborated, wherein:
Fig. 1 is traditional source of welding current structure, and wherein partial cover plate is removed;
Fig. 2 is that wherein partial cover plate is removed according to source of welding current structure of the present utility model.
Embodiment
Referring to Fig. 2, show according to source of welding current structure of the present utility model.This power supply architecture divides three layers, and it is preferably sealed type at the middle and upper levels, and middle level and lower floor are open, and the side plate of middle level and lower floor and base plate can have shutter.In the upper strata, the driving P plate of power device, control transformer etc. are set on the dividing plate between upper strata and the middle level.Because the upper strata is a sealed type, therefore the above-mentioned electrical part product that can avoid being arranged in wherein are subjected to the invasion and attack of dust, thereby have improved reliability.Middle layer cloth is equipped with cooling fan and radiator, and lower floor is furnished with main transformer and reactor.
According to the utility model, in the middle level, be adjacent to be provided with an independent annular seal space with preceding control panel, master control P plate is vertically placed in it.Like this, the sealing chamber can prevent entering of dust, has isolated the influence of pyrotoxin simultaneously, and the vertical placement of master control P plate has effectively been avoided piling up because of the dust that long-term use easily causes.The top of preceding control panel is furnished with display panel, switch, potentiometer, protective tube etc., and can be provided with an openable cover plate in the preceding control panel position corresponding with the middle level annular seal space, this cover closure described annular seal space, can pick and place master control P plate after opening.
Claims (3)
1. the overall structure of a source of welding current, it is divided into upper, middle and lower-ranking, the upper strata is provided with the electrical part product of the driving P plate that comprises control transformer and power device, the middle level is provided with cooling fan and radiator, lower floor is provided with main transformer and reactor, and source of welding current front portion is preceding control panel, it is characterized in that, be adjacent to be provided with an annular seal space with preceding control panel in the middle level, master control P plate is arranged in the sealing chamber vertically.
2. the overall structure of the source of welding current according to claim 1 is characterized in that, is provided with an openable cover plate with the corresponding position of described annular seal space on preceding control panel.
3. the overall structure of the source of welding current according to claim 1 and 2 is characterized in that, described upper strata is a sealed type, and described middle level and lower floor be open.
