Abstract
The utility model discloses an anti-explosion and pressure release structure of a wiring device for a motor and electrical equipment, which comprises a base plate of the wiring device, wherein air release holes are formed on the base plate; a cover lid (the two opposite sides of the cover lid being welded on the base plate) is arranged on the air release hole on the outer side surface of the base plate; a copper plate, which is less than or equal to 0.5mm in thickness, covers the air release hole on the inner side surface of the base plate; and a pressing plate, which is connected with the base plate, is arranged on the copper plate. During the operation progress of the motor, once the wiring device is subjected to arc discharge phenomenon, high-temperature and high-pressure air can move the copper plate of 0.5mm through jacking, so that air in the wiring device is released; in addition, the cover lid, which is arranged on the outer side surface of the base plate of the wiring device, plays a very good role in baffling, in this way, the operation reliability of the motor and the electrical equipment is greatly improved.
Description
Technical field
The utility model relates to the electrical equipment and electrical technical field, is specifically related to high, normal, basic voltage Electric Machines and Electric Apparatus equipment explosion-proof relief structure.
Background technology
At present, the termination of high, normal, basic voltage Electric Machines and Electric Apparatus all is enclosed structural design; Do not have pressure relief channels, this structural design exists following defective: under the situation that suspended particulate substance increases in, the air big in voltage fluctuation, air humidity, termination inside very easily produces the arcing phenomenon; In case electric arc occurs; In the termination that seals, can produce high temperature and high pressure gas rapidly, when pressure acquires a certain degree, can blow termination, to people's life security generation threat.
Summary of the invention
The purpose of the utility model is to provide a kind of termination explosion-proof relief structure of Electric Machines and Electric Apparatus, in case this structure can effectively solve termination generation arcing phenomenon, pressure relief just can discharge high temperature and high pressure gas, overcomes the defective of prior art.
For achieving the above object, the technical scheme of the utility model is:
High, normal, basic voltage Electric Machines and Electric Apparatus equipment explosion-proof relief device; The base plate that comprises termination; Said base plate is provided with the gas release hole; The gas release hole of plate outer side face is provided with cover cap (two relative edges of cover cap are welded in base plate), is stamped smaller or equal to 0.5mm thick metallic plate on the gas release hole of base plate medial surface, and said metallic plate is provided with the pressing plate that is connected with base plate.
The further improvement project of the utility model is; Said pressing plate is provided with the release aperture consistent with base plate, and pressing plate lower surface release aperture periphery is provided with L shaped breach, and the metallic plate periphery stretches in the L shaped breach; Pressing plate is pushed down the metallic plate periphery, through connector pressing plate is connected in base plate.
The utility model further improvement project is between the joint face of pressing plate and metallic plate and base plate, to be provided with seal washer.Said metallic plate is copper coin or aluminium sheet.
The beneficial effect of the utility model:
In motor operation course, in case termination generation arcing phenomenon, high temperature and high pressure gas just can back down the copper coin of 0.5mm (its periphery is pulled out) in L shaped breach, the gas release in the termination is fallen.Because the lateral surface at the termination base plate is provided with cover cap, this cover cap has played extraordinary barrier effect, has ensured safety in production, has increased the Electric Machines and Electric Apparatus reliability of operation greatly.
Description of drawings

Fig. 2 is connected in the pressing plate sketch map of base plate for Figure 1A direction.
Embodiment
As shown in Figure 1, the utility model comprises the base plate 1 of termination, and said base plate 1 is provided with gas release hole 7, and the gas release hole 7 of base plate 1 lateral surface is provided with cover cap 6, and two relative edges of said cover cap 6 are welded in base plate 1.Like Fig. 1, shown in 2, be stamped the thick copper coin of 0.5mm 4 on the gas release hole 7 of base plate 1 medial surface, said copper coin 4 is provided with the pressing plate 5 that is connected with base plate 1.
As shown in Figure 2; Pressing plate 5 is provided with the gas release hole 8 consistent with base plate 1, and said release aperture 8 peripheries of pressing plate 5 lower surfaces are provided with L shaped breach, and copper coin 4 peripheries stretch in the L shaped breach; Pressing plate 5 is pushed down copper coin 4 peripheries, through connector 3 pressing plate 5 is connected in base plate 1.
Still as shown in Figure 2, between the joint face of pressing plate 5 and copper coin 4 and base plate 1, be provided with seal washer 2.
Though the utility model is described with reference to the above embodiments; But those of ordinary skill in the art; Will be appreciated that above instance only is to be used for explaining the utility model; Should understand and wherein can make variations and modifications and do not break away from the utility model in a broad sense; So be not as qualification, as long as in the connotation scope of the utility model, to the variation of above-described embodiment, the protection range that distortion all will fall into the utility model claim to the utility model.
