Abstract
The utility model discloses a capacitor explosion-proof box for a rectifying device, which comprises a box body. The capacitor explosion-proof box is characterized in that a capacitor mounting hole and a long heat-dissipating hole are arranged on the inner side of the bottom surface of the body of the capacitor explosion-proof box; and a long heat-dissipating hole is arranged on the top surface of the box body. When a capacitor in a filter circuit explodes, the capacitor explosion-proof box can be used for limiting the explosion in the limited space, preventing the splashed electrolyte from damaging other components or injuring other operators and reducing the hazard to be minimized.
Description
Technical field
The utility model relates to a kind of electric capacity explosion-proof tank, specifically is meant a kind of electric capacity explosion-proof tank that is used for rectifying device.
Background technology
In rectifying device, electrochemical capacitor is widely used as filter.The capacitor group of rectifying device is because the operating time is long, and live load is big, happens occasionally so capacitor expands the situation of explosion, blast.When capacitor blast or explosion, electrolyte inside is splashed or is overflowed, if be splashed on the critical component in the circuit, cause short circuit, gently then damage controller switching equipment, heavy then initiation fire is if having the staff nearby when blasting, also might cause personal injury, safety in production is caused very big harm.So for rectifying device, the explosion-proof design of filtering capacitor is most important.
Existing rectifying device filter capacitor is exposed usually to be installed, or only simple and other critical components isolation by baffle plate, not enough to the potential safety hazard protection that electric capacity is blasted.
The utility model content
The purpose of this utility model is to provide a kind of electric capacity explosion-proof tank that is used for rectifying device, when this electric capacity explosion-proof tank can the capacitor in filter circuit be blasted, blast is limited in the confined space, the electrolyte of avoiding splashing injures other parts or operating personnel, makes harm drop to minimum.
The utility model is realized by the following technical solutions: a kind of rectifying device electric capacity explosion-proof tank, comprise casing, it is characterized by: the tank floor inboard of described electric capacity explosion-proof tank has electric capacity installing hole and heat radiation slotted hole, also has the heat radiation slotted hole on the end face of described casing.
For the ease of installing and assembling, the utility model can be done following improvement: described explosion-proof tank is interconnected and is formed by installation base plate, shell, cover plate.
For the ease of installing and assembling and increase insulativity, the utility model can also be done further improvement: the casing of described explosion-proof tank is a rectangle, and described shell is that metal is made, and described installation base plate and cover plate are that insulating material is made.
For the heat that capacitor is produced can in time distribute, avoid temperature rise too high, the utility model can also be done following improvement: described explosion-proof tank metal shell has a plurality of louvres on four sides, and described installation base plate and cover plate have the heat radiation slotted hole that is parallel to each other.
Be connected with external circuit for the ease of the capacitor group, the utility model can also be done following improvement: described electric capacity explosion-proof tank also comprises conductive bus bar and the busbar support bar that is parallel to described heat radiation slotted hole installation, described conductive bus bar is erected at described cover plate top by the busbar support bar, and described busbar support bar is fixed on the shell of described casing.
The utility model can also be done further improvement: described electric capacity explosion-proof tank also comprises buckle, and described buckle has orthogonal two sides, respectively with described shell and cover plate snapping, thereby with the seam fastening of shell and cover plate.
During use, a plurality of electric capacity are fixed on by described electric capacity installing hole forms the capacitor group on the installation base plate of described electric capacity explosion-proof tank, and described capacitor group is carried out circuit by described conductive bus bar and external circuit and is connected.
Advantage of the present utility model is: designed the casing of metal shell for the exposed originally capacitor group of installing or using baffle plate simply to isolate, blast or during explosion when capacitor like this, the scope that electrolyte can be overflowed or splash is confined to box house, avoid causing large-scale circuit to damage or personal injury, reduced potential safety hazard.
In addition, the installation base plate of the electric capacity explosion-proof tank of the utility model design and cover plate all adopt insulating material to make, and have improved the insulation property of explosion-proof tank, effectively prevent the generation of the bad or short circuit that blast causes of lead wire technology.
At last, have a plurality of louvres around the shell of described electric capacity explosion-proof tank, described installation base plate and cover plate also have the heat radiation slotted hole, and the heat of the electric capacity generation when work that is installed in the casing is in time distributed, and temperature rise is too high breaks down because of working effectively to avoid electric capacity.
