Abstract
The utility model relates to a special explosion-proof sheath for rectifying elements. At present, no explosion-proof sheath is arranged on a rectifying element when the rectifying element is press-installed, and the rectifying element cannot be fixed and is easy to fall off and damage when being press-installed and replaced. The special explosion-proof sheath for rectifying elements comprises a rectifying element sheath and a bus fixing plate, wherein the rectifying element sheath is circular, is arranged in the center of the bus fixing plate and is of an integrated structure. With the special explosion-proof sheath adopted, a rectifying element can be conveniently installed and replaced and can be prevented from spraying electric arcs outward, and an anode and a cathode of a single rectifying element as well as shells of adjacent rectifying elements can be separated.
Description
Technical field
The utility model relates to a kind of explosive-proof jacket of rectifier cell special use.
Background technology
In heavy-duty rectifier, every rectifier cabinet has tens of, even nearly hundred rectifier cells, the press-fiting and protect the safe operation that directly affects rectifier of rectifier cell.
Rectifier is in running, and the voltage at rectifier cell two ends is up to thousands of volts.If rectifier cell breaks down, outer casing rupture will spray electric arc outward, if electric arc is sprayed onto on all the other elements, will cause the system failure outward; Even rectifier cell is working properly, because the distance between the rectifier cell anode and cathode is very little, when the equipment long-time running, the rectifier cell shell is easily long-pending dust or other impurity, make produce between the rectifier cell anode and cathode creepage, even short circuit.
Do not install explosive-proof jacket when at present, rectifier cell press-fits additional.Press-fiting and changing in the process of rectifier cell, rectifier cell can't be fixed, and easily drops, and damages.
The utility model content
Problem to be solved in the utility model provides a kind ofly can install rectifier cell, negative and positive the two poles of the earth of single rectifier cell, adjacent rectifier cell shell can also be separated the explosive-proof jacket of rectifier cell special use.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
A kind of explosive-proof jacket of rectifier cell special use, its special character is: comprise rectifier cell sheath, bus fixed head, the rectifier cell sheath is circular, the rectifier cell sheath is arranged on the center of bus fixed head and is the integral type structure.
The both sides of above-mentioned bus fixed head are provided with screw, and the bus fixed head is fixed by screw, bolt and bus.
Above-mentioned rectifier cell sheath and the size of rectifier cell coupling, rectifier cell is arranged in the rectifier cell sheath.
Compared with prior art, the utility model not only is convenient to the rectifier cell installation, changes, and can also prevent the outside spray arc of rectifier cell, and negative and positive the two poles of the earth of single rectifier cell, adjacent rectifier cell shell are separated.
Description of drawings
Fig. 1 is structure chart of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, the utility model comprises rectifier cell sheath 1, bus fixed head 2, and rectifier cell sheath 1 is circular, and rectifier cell sheath 1 is arranged on the center of bus fixed head 2 and is the integral type structure.
The both sides of above-mentioned bus fixed head 2 are provided with screw, and bus fixed head 2 is fixed by screw, bolt and bus.
Above-mentioned rectifier cell sheath 1 mates with the size of rectifier cell, and rectifier cell is arranged in the rectifier cell sheath 1.
The utility model not only can be installed rectifier cell, negative and positive the two poles of the earth of single rectifier cell, adjacent rectifier cell shell can also be separated.
