Detailed Description
It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.
The following detailed description of the embodiments of the invention is provided.
A general explosion-proof capacitor holder is shown in figures 1 to 6 and comprises a holder body 1 and a protective cover 2 at one open end of the holder body; the frame body comprises a bottom hoop 3, a top hoop 4 and a plurality of explosion-proof plates 5 arranged between the bottom hoop and the top hoop; the explosion-proof plate 5 is of a telescopic structure and comprises a base part 6 fixedly connected with a bottom hoop and an expansion part 7 fixedly connected with a top hoop; the protective cover is of a two-piece structure which is buckled with each other and comprises a left cover body 8 and a right cover body 9; the left cover body and the right cover body are fixed on the top hoop through a plurality of connecting pieces 10, and each connecting piece is perpendicular to the plane where a seam 11 of the left cover body and the right cover body is located. The explosion-proof plates are uniformly distributed along the circumferential direction of the top hoop/the bottom hoop, the structural stability is good, and the fixed capacitor is stable and reliable. The explosion-proof plate can effectively reduce the damage caused by the side explosion of the capacitor.
The bottom hoop comprises a plurality of sections of first attaching and fixing parts 12, and a first fold buffer adjusting part 13 is arranged between every two first attaching and fixing parts. In general, the first wrinkle buffer adjustment portion has a flexible corrugated plate structure.
The top hoop comprises a plurality of sections of second attaching and fixing parts 14, and a second fold buffer adjusting part 15 is arranged between every two second attaching and fixing parts. In general, the second wrinkle buffer adjustment portion has a flexible corrugated plate structure.
When utilizing this holder centre gripping fixed capacitance, embolia electric capacity from bottom hoop one end earlier, when the electric capacity external diameter is great, the fold buffer adjustment portion can expand to electric capacity, and stable clamping force of electric capacity can be given to bottom hoop and top hoop, guarantees the stability of electric capacity, in addition, can adjust the explosion-proof board according to the height of electric capacity, so, this holder can adapt to the electric capacity of multiple specification, and the commonality is good.
The connecting piece adopts a full-thread bolt, so that the left cover body and the right cover body can be conveniently fixed. Because each connecting piece all is perpendicular to the plane at left cover body and right cover body seam place, reliably forms fixed action to left and right cover body, runs through the connecting piece and fixes the protection casing behind the top hoop, and left and right protection casing is to the degree of freedom of opening the direction limited, even its inside receives the impact of electric capacity grout explosion, also can not open. The through-arranged connecting piece also plays a role in blocking the impact when the capacitor bursts.
The inner wall of the left cover body is provided with a left protective tooth 16 extending to the inner side of the right cover body, the inner wall of the right cover body is provided with a right protective tooth 17 extending to the inner side of the left cover body, and the left protective tooth and the right protective tooth are staggered.
The top hoop and the bottom hoop are both made of nylon materials, and have the advantages of high strength, aging resistance and the like. In addition, the first attaching fixing parts and the first wrinkle buffer adjusting parts of the bottom hoop and the second attaching fixing parts and the second wrinkle buffer adjusting parts of the top hoop can be made into an integrated structure, so that the structural strength is effectively guaranteed, the reliability is high when the structure is impacted, and the stability is good.
In an alternative embodiment, the inner wall of the base is provided with a plurality of spurs 19, the spurs may be of a cone-shaped structure as a whole, but the tips of the spurs do not need to be of a sharp and sharp needle-point-shaped structure, but may be of a spherical structure (a ball-head-shaped structure), and in a normal state, the capacitor is firmly fixed, and at the same time, the capacitor cannot be damaged by the outer shell of the capacitor and cannot be penetrated into the shell. The end of the stabs with a spherical structure is used for avoiding the deformation of pits and the like on the surface of the capacitor shell under normal conditions.
Therefore, the stabs which cannot puncture the capacitor shell in a normal state are arranged, and the stabs are only arranged on the inner wall of the base part and not on the inner wall of the expansion part in order to ensure the stability of clamping the capacitor. The method is used for ensuring that once the capacitor is suddenly high in temperature and bursts, the damage caused by the capacitor bursting is minimized. Each spur clung to the capacitor shell in a normal state can be clung to the capacitor shell, when the capacitor is about to burst at an abnormal high temperature, the capacitor shell can be thermally expanded to a certain degree, at the moment, the plurality of spurs can simultaneously puncture the capacitor shell, the pressure of the capacitor is relieved to the maximum extent, the impact force generated by the content pressure of the capacitor is reduced, the passive defense against the capacitor burst is formed, and the safety is improved.
It should be noted that, what degree the capacitor case expands (there is a certain evaluation standard through the perimeter or diameter of the case) has a possibility of bursting, which can be obtained by a person skilled in the art through experiments or experience values in advance, and what degree the set stabs the capacitor when the capacitor expands can be controlled through the length of the stabs (here, "control" actually means that the longer the length of the stabs in a normal state, the closer the stabs are to the capacitor case, the easier the stabs the capacitor case, or conversely, a certain amount of expansion of the capacitor case is allowed under the condition that a certain gap exists between the stabs and the capacitor case), and the capacitor case is pierced by a plurality of stabs at the same time, so as to avoid the damage caused by liquid splashing inside the capacitor due to too high single-split pressure, so as to maximally perform passive defense against the capacitor bursting, and greatly reduce the loss.
Because the capacitor is cracked from the top of the capacitor mostly during slurry explosion, in an optional embodiment, an inner buffer plate 18 is arranged on the expansion part of the explosion-proof plate, generally, the inner buffer plate is in an inverted U-shaped structure, and another protective measure is formed by the inner buffer plate to reduce damage caused by slurry explosion. And the two ends of the inner buffer plate are correspondingly arranged on the inner buffer plates of the explosion-proof plates at the two sides respectively.
The combination of active protection and passive defense is realized by the aid of the inner buffer plate, the protective cover and the spurs on the inner wall of the base, and once slurry explosion occurs, the capacitor shell can be punctured by the spurs to realize pressure relief and reduce impact when the top of the capacitor bursts. Of course, the capacitor shell is also allowed to be pierced by the spurs and the top of the capacitor is burst simultaneously, the arranged inner buffer plate forms a first protective barrier, actually, a connecting piece penetrating through the protective cover in a whole body plays a second protective barrier, and the left and right protective teeth which are mutually staggered and disassembled form a third protective barrier. The protective cover is used as the last fourth protective barrier, and due to the blocking of the first three protective barriers, the protective cover cannot be impacted greatly, the slurry splashing effect is mainly prevented, the damage caused by capacitor slurry explosion is effectively avoided, the personal safety is not injured, and the risk and the damage degree are reduced to the minimum.
