The utility model discloses simple structure, low in manufacturing cost can hinder the high pressure of production by safety -release cubical switchboard cable chamber for some reason, guarantees to release the safety of pressure, can effectively solve the pressure release problem of the built on stilts business turn over tape generating line bridge scheme in cable chamber top simultaneously.
Description
Technical field
The utility model relates to power transmission and distribution field, particularly relates to a kind of switch cubicle cable vault pressure relief device.
Background technology
Middle pressure switchgear assembly is a kind of product applied in electric power system widely, and it assume responsibility for the important function of controlling electric energy, dispensing.Particularly 3.6 ~ 40.5kV armored AC metal closed formula switchgear is that current transformer station and terminal use select maximum a kind of products, and its reliability service is directly connected to the personal safety of operation maintenance personnel and the continuity of power supply.Because the switchgear of main flow is in reduced volume at present, while improving protection against electric shock degree of protection, also exist another kind of dangerous, namely when inside switch cabinet occur because of product insulation level decline, foreign matter such as to enter at the many reasons, when inside switch cabinet forms phase fault, the heat energy that arc light produces can make compartment interior gas sharply swollen bulging become blast and damage equipment, even threaten the personal safety of operator on duty.So according to national standard and State Grid Corporation of China regulation, a room of switchgear must be provided with interior unit cell model pressure relief channels, when there being above-mentioned situation to occur, can from one comparatively weakness place the place of compartment interior pressure to safety is discharged.
Concerning under regular situation, this is an easy to reach technical requirement, general switchgear assembly producer by arranging an openable metal cover board on switch cabinet top, when occur arc fault time, this block metal cover board can be opened by inner gases at high pressure, relieving pressure.But when running into top, cable vault and making somebody a mere figurehead the scheme of line band bus bridge, adpting flange due to bus bridge chair can take the space at switch cubicle top, and the high temperature in switch cubicle, gases at high pressure more can not discharge in bus bridge, so this kind of scheme is just existed to the not meeting property of product, and there is potential safety hazard.
Utility model content
The utility model aims to provide a kind of switch cubicle cable vault pressure relief device, solves top, cable vault when making somebody a mere figurehead line band bus bridge scheme, when there is arc fault, and can the pressure of safe release cable vault.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The utility model is disclosed a kind of, comprise cable vault, pressure release passage and release of pressure cover plate, visit and rear Xiamen after comprising after described cable vault, visit after described and be arranged on the upside of rear Xiamen, after visit and be provided with ventilation hole, described pressure release passage is arranged on disposed at air vent, the upper end of pressure release passage with after upper end of visiting flush, pressure release passage end face is provided with relief hole, the upper end cover in relief hole of visiting after described release of pressure cover plate is arranged on.
Further, described release of pressure cover plate with after to visit upper end thereof.
Further, described pressure release passage comprises side shield, backboard, overhead gage and lower baffle plate, described side shield has two pieces, be arranged on two vertical edges of backboard, described overhead gage is arranged on the upper end of backboard and is connected with the upper end of two pieces of side shields, described lower baffle plate is arranged on the lower end of backboard obliquely and is connected with the lower end of two pieces of side shields, the open-front of described pressure release passage, the open end of described pressure release passage with after visit and be connected.
Further, described side shield and lower baffle plate with after visit and be connected one end and be provided with outside bending edges, described bending edges is provided with installing hole.
Further, upper ventilation hole surrounding of visiting after described is provided with screwed hole.
Further, described ventilation hole is rectangular opening.
Further, described relief hole is rectangular opening.
The utility model has following beneficial effect: structure is simple, low cost of manufacture, the gases at high pressure that energy safe release switch cubicle cable vault produces because of fault, ensure the safety of release of pressure, effectively can solve the pressure release problem that line band bus bridge scheme is maked somebody a mere figurehead at top, cable vault simultaneously.
