Embodiment
Below in conjunction with description of drawings the present invention is specifically described:
As shown in Figure 1: the present invention includes the A of control room that is arranged in the cabinet 1, handcart chamber, upper strata B, the handcart chamber C of lower floor, the D of cable vault, main bus bar chamber E, the handcart chamber pressure release channel F of lower floor, the cabinet front and back end is provided with cabinet door 2, the preceding upper end of cabinet 1 is provided with the A of control room, the front middle part of cabinet is the relevant position that handcart chamber, B(upper strata, handcart chamber, upper strata is positioned at existing middle switchgear handcart chamber), be provided with the pressure relief channels 3 of handcart chamber, upper strata at the rear, control room, the rear of handcart chamber, upper strata is provided with main bus bar chamber E and the D of cable vault, the handcart chamber comprises handcart chamber, upper strata and lower floor handcart chamber, the handcart chamber C of lower floor is positioned at the below of handcart chamber, upper strata, the hypomere part at rear, handcart chamber, upper strata and the epimere at rear, lower floor handcart chamber partly are provided with main bus bar chamber E, above the main bus bar chamber and the epimere at rear be the D1 of cable vault, upper strata, below the main bus bar chamber and the hypomere at rear be the D2 of cable vault of lower floor, below lower floor handcart chamber and lower floor cable vault, be provided with the handcart chamber pressure release channel F of lower floor, above the cable vault, upper strata, be provided with pressure relief opening 4, lower floor's handcart chamber pressure release channel pass the lower floor cable vault through check valve sheet and cable vault, upper strata to pressure relief opening.Pressure relief opening can make the present invention when producing fault, in time the cabinet gas inside is discharged into the external world.
Isolate by dividing plate 5-1 between lower floor handcart chamber and lower floor cable vault and the lower floor's handcart chamber pressure release channel, dividing plate between lower floor's handcart chamber pressure release channel and the lower floor handcart chamber is provided with through hole 6-1, and through hole is positioned on the position of close lower floor handcart chamber rear wall; Dividing plate between lower floor's handcart chamber pressure release channel and the lower floor cable vault is provided with through hole 6-2, and through hole is positioned near on the position of cabinet rear wall.By through hole is set, gases at high pressure via through holes, lower floor's handcart chamber pressure release channel that lower floor handcart chamber is produced when producing fault are dredged to the external world.
Isolate by dividing plate 5-2 between cable vault, upper strata and lower floor cable vault, dividing plate is provided with air vent hole 7, and air vent hole is provided with check valve sheet 8.Air vent hole is in order to dredge gas, and check valve sheet is set on air vent hole, and is separate when having guaranteed normally to move in upper and lower layer cable vault, do not disturb mutually.When break down in the lower floor loop, the air-flow that is produced backs down unidirectional dividing plate, makes the gas abrupt release.
The rear wall of main bus bar chamber is provided with the reticulated cell 9 that is used for release pressure, is used to discharge the indoor gas of main bus bar.
Pressure relief opening is provided with pressure releasing activity plate 4-1, and pressure releasing activity plate fixes on the cabinet top by hinges fixing and covers on pressure relief opening 4.
As shown in Figure 2: a side of check valve sheet is provided with row aperture 8-1 easy to break, and a side that has aperture easy to break is fixed on the dividing plate, and opposite side is locked on the dividing plate slightly by screw, and wherein screw is slight check valve sheet is fixed on the dividing plate.When producing high voltage fault gas, air-flow is with check valve sheet top upwards, and a side that makes check valve sheet have screw is backed down screw, and a side that has aperture easy to break is by bending, thereby gas is discharged smoothly.
Below operation principle of the present invention is described:
When the present invention was in normal operating conditions, handcart moved to the service position, and this moment, the place ahead and the rear of handcart isolated.Sealing effectiveness meets IP2X sealing grade.During handcart generation arc fault, the gases at high pressure that produced can be not directly discharge from the direction of cabinet door, but discharge by pressure relief opening.
When the indoor generation arc fault of upper strata handcart, the gases at high pressure that the produced top of the passage by the rear, control room, passage successively are provided with pressure relief opening and discharge.
When the indoor generation arc fault of lower floor's handcart, the gases at high pressure that produced discharge by lower floor's handcart chamber pressure release channel, lower floor cable vault, check valve sheet, cable vault, upper strata, the pressure relief opening that is provided with by the cabinet top at last successively.
When arc fault took place in the lower floor cable vault, the gases at high pressure that produced discharged by check valve sheet, cable vault, upper strata, the pressure relief opening that is provided with by the cabinet top at last.
When in the cable vault, upper strata arc fault taking place, the gases at high pressure that produced directly discharge by the pressure relief opening that the cabinet top is provided with.
When the indoor generation arc fault of main bus bar, the gases at high pressure that produced are by the cable vault, upper strata, and the pressure relief opening that is provided with by the cabinet top discharges afterwards.
The present invention makes full use of the switchgear useful space, issuable inner arcing fault stream pressure was discharged outside the cabinet by rational pressure relief channels when switchgear was moved, prevent that fault from spreading mutually, reach adjacent switch device security reliability service, guarantee the purpose of maintenance operation personal security.By a shared main bus bar chamber, two loops and control room up and down are set, can save the space like this and reduce occupation area of equipment.This equipment is two independently loop power supplies simultaneously, double-deck handcart cell structure, each handcart chamber all is a pressure relief channels independently, in case break down in a loop, the fault air-flow of its generation can be discharged outside the cabinet rapidly along respective channel, do not influence main bus bar chamber and neighbouring device, the security reliability height.
