Abstract
The utility model relates to an electrical connection mode in a capacitor and an explosive-proof device of an explosive-proof capacitor. The utility model solves the problem that the utility model provides a safety environmental-protective explosive-proof capacitor which has the advantages of environmental protection, high operational reliability and relatively lower cost. The utility model is characterized in that the electrical connection among the components in the capacitor can be realized in a mode of spot welding, the pollution caused by welding of lead tin materials can be avoided and the cost is reduced. On the other hand, a notch which is added on an explosive-proof piece raises the explosive-proof sensitivity and the explosion protection reliability of the device.
Description
Technical field
The utility model relates to noinductive capacitor.
Background technology
Present widely used noinductive capacitor has two kinds, structure one: its burst disk and copper core and the slicker solder material by the soft fine weldering of flatiron of being electrically connected all that covers outward between the conductive pole weld and realize.Along with the raising of people's sense of self-protection, require to use environment-friendly materials, and contain a large amount of heavy metals such as lead inevitably, serious harm people's health in the plumber's solder of the soft fine weldering of flatiron.On the other hand, the cost of this explosion-protection equipment is higher.
Structure two: its explosion-protection equipment uses soft copper sheet directly to be connected between the gilding layer of conductive pole and capacitor element on the shell, though this soft copper sheet can be connected with the spot welding mode with conductive pole, but the contact area when being connected with the gilding layer of capacitor element owing to this soft copper sheet is big, the conductive resistance that adds copper is low, can't realize being electrically connected by spot welding, still need use plumber's solder, increase cost.In addition; owing to do not have breach on the burst disk of this structure; when explosion-protection equipment moves; bonding pad on the burst disk does not have directivity with the disengaging that covers tie point outward; break down to cut off the electricity supply the time at capacitor, cause incomplete disengaging easily, even still keep being electrically connected; do not reach desirable safeguard protection performance, and cost is higher.
Summary of the invention
The purpose of this utility model is: a kind of environment-friendly type, functional reliability height, the relatively low environment-friendly type safety noinductive capacitor of cost are provided.
The technical solution that realizes the foregoing invention purpose is such:
The environment-friendly type safety noinductive capacitor, comprise element group and explosion-proof mechanism, described element group comprises plastics positioning sleeve 1, capacitor element 2, copper core 3, gilding layer 4, shell 14 and mandrel 15, and described explosion-proof mechanism comprises bursting diaphragm 5, insulating board 6, sealing ring 7, enclosing cover 8, insulator 9, quick connection terminal 10, conductive pole 11, burst disk 12 and location bearer bar 13; It is characterized in that: fixedly connected for spot welding between described burst disk 12 and the copper core 3; Fixedly connected for spot welding between copper core 3 and the gilding layer 4; Fixedly connected for spot welding between burst disk 12 and the conductive pole 11; Fixedly connected for spot welding between conductive pole 11 and the quick connection terminal;
Described burst disk 12 is copper sheet or iron plate, and burst disk 12 is provided with a fracture port with conductive pole 11 junctions.
Fracture port is an arc on the described burst disk 12.
The useful technique effect of the utility model is: owing to adopt dc spot welding to replace the slicker solder material welding of the soft fine weldering of flatiron, make and the complete compliance with environmental protection requirements of the product and the course of processing reduced cost again; On the other hand, the breach that burst disk and conductive pole junction increase, when capacitor broke down inefficacy, conductive pole is outwards outstanding to break away from fully with burst disk, has improved the explosion-proof sensitivity and the reliability of device.
Description of drawings
Accompanying drawing 1 is an internal structure schematic diagram of the present utility model.
Accompanying drawing 2 is the structural representation after the explosion-protection equipment action.
Accompanying drawing 3 is the burst disk structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to accompanying drawing 1; the environment-friendly type safety noinductive capacitor comprises plastics positioning sleeve 1, capacitor element 2, copper core 3, gilding layer 4, bursting diaphragm 5, insulating board 6, sealing ring 7, enclosing cover 8, insulator 9, quick connection terminal 10, conductive pole 11, burst disk 12, location bearer bar 13, shell 14 and mandrel 15.
Fixedly connected for spot welding between burst disk 12 and the copper core 3; Fixedly connected for spot welding between copper core 3 and the gilding layer 4; Fixedly connected for spot welding between burst disk 12 and the conductive pole 11; Fixedly connected for spot welding between conductive pole 11 and the quick connection terminal.
Burst disk 12 is copper sheet or iron plate, comprise spot welding bonding pad that is connected to conductive pole 11 and the Welding Area that is connected to copper core 3, see Fig. 3, its shape, position and direction can be carried out suitable adjustment by technological requirement, burst disk 12 has a fracture port 16 with conductive pole 11 spot welding junctions, and fracture port 16 is a semicircular arc.
Capacitor element 2 is wound on the capacitor mandrel 15 for metallized film, and the gilding layer at two ends is the extraction pole of capacitor.Described gilding layer 4 is connected on the conductive pole 11 by copper core 3 and burst disk 12 respectively.Pack into after capacitor element 2 usefulness plastics positioning sleeves 1 are sealed in the shell 14, this shell 14 forms the container that seals with enclosing cover 8.When the pressure in this airtight container raise rapidly, enclosing cover 8 distortion backs were outwards outstanding, and the conductive pole 11 on the enclosing cover 8 is moved up, and see shown in the accompanying drawing 2.
Its operation principle is:
When capacitor breaks down inefficacy, the dielectric of capacitor element 2 decomposes, and produces a large amount of gas rapidly, and the pressure in the airtight container that enclosing cover 8 and shell 14 form raises rapidly, make enclosing cover 8 distortion backs outwards outstanding, the conductive pole 11 on the enclosing cover 8 also outwards moves.Because bursting diaphragm 5 adopts resistant to elevated temperatures rigid plastics to make, do not produce distortion under pressure, move when having stoped burst disk 12 and conductive pole 11, the pulling force of formation finally disconnects this spot welding and connects, thereby the dump of fault capacitor is reached explosion-proof purpose.Because the breach on the burst disk 12, be under pressure pulling conductive pole 11 when outwards outstanding at enclosing cover 8, be easier on the burst disk 12 the semicircular arc fracture port 16 of spot welding bonding pad and tear, conductive pole 11 and burst disk 12 are broken away from fully.
