Property determines.When capacitor under alternating voltage in use, often indicate the capacity of capacitor with its reactive power, unit be it is weary or
Kilovar.Currently, due to height above sea level, air pressure is low, conventional capacitive when capacitor is in place operation of the height above sea level beyond 2000 meters
Device internal pressure greatly with the problem of it is easy to appear casing deformations when external pressure.This problem does not only result in the insulation of capacitor
Performance decline, also causes security risk to the operation to capacitor.
Utility model content
The purpose of this utility model, which is that, overcomes existing technical problem, provides a kind of plateau type high voltage three phase parallel
Capacitor case.
In order to achieve the above objectives, the utility model is implemented according to following technical scheme：
A kind of plateau type high voltage three phase parallel capacitor shell, the capacitor case top are fixedly connected with lead-out wire porcelain
Set；The capacitor case includes inner housing, outer housing, several reinforcing ribs, reinforcing sleeve；
The reinforcing rib is rectangular box-like；The equidistant lock ring vertical from top to bottom of the reinforcing rib is outside inner housing；It is described
Reinforcing sleeve is an integral structure, including upper plate, lower plate, foreboard, back plate；The foreboard vertical direction has several through slots；On described
Plate has strut, supporting plate；There is through-hole on the supporting plate, is located at upper plate center；The supporting plate connects the side of upper plate by strut
Edge；The lead to the hole site of the supporting plate is consistent with the number of positions of lead-out wire insulator with quantity；The back plate is identical as front board structure；
The lower plate is identical as upper plate structure；The reinforcing sleeve is mounted on outside reinforcing rib；
The outer housing is located at outside reinforcing sleeve；The outer housing forms for plate welding；The front and back of the outer housing is left
The right side is that monolith flat plate buckling forms；The monolith plate is welded to connect integral before outer housing；It is described in outer housing
Structure bends inwards for left side plate and is overlapped in weld right end plate at the welded connecting of front；
The outer housing, inner housing upper surface have through-hole；The lead to the hole site and quantity of the outer housing and inner housing
It is consistent with the number of positions of lead-out wire insulator.
Preferably, the foreboard of the reinforcing sleeve mutually correlates with before outer housing.
Preferably, the reinforcing rib is high-intensitive material；The reinforcing sleeve is polytetrafluoroethylene material.
The action principle of the utility model：
The utility model includes inner housing, outer housing, several reinforcing ribs, reinforcing sleeve.Inner housing is common capacitor
Shell, outside increases reinforcing rib, reinforcing sleeve and outer housing.
Reinforcing rib lock ring increases the intensity in inner housing peripheral direction in the surrounding of inner housing to a certain extent；Add
It covers on the outside of reinforcing rib by force, strengthens the intensity of upper and lower front-back.
For the structure of reinforcing sleeve, upper plate selection supporting plate, the strut of reinforcing sleeve are constituted, on the one hand the structure section of this hollow out
Material saving facilitates heat dissipation, on the other hand facilitates the installation of lead-out wire insulator, but also increases the intensity of top and bottom again simultaneously.Similarly,
The front-back of reinforcing sleeve is provided with through slot also for the problem of saving material and heat dissipation.
Outer housing then works it out different processing in welding, takes using using plate with two plates after the multi-faceted bending of plate
It connects.Same plane is still held after capacitor case inner wall overlap joint, does not influence capacitor cover plate, bottom plate not only in conjunction with capacitor tank wall
Sealing performance guarantee its aesthetic appearance again；It is mentioned by changing shell binding site and mode, anti-negative pressure ability than original structure
It is 1.7 times high.
The utility model has reached following beneficial effect：
The utility model structure is simple, easy for installation；The reinforcing rib, reinforcing sleeve of the utility model increase outside inner housing
Intensity, prevent inner housing internal pressure high, deformed caused by altitude environment air pressure is low；Outer housing is the outermost protective shell of capacitor
Body, by changing shell binding site and mode, anti-negative pressure ability improves 1.7 times than original structure.
